The PSD4XX products also provide a powerful microcontroller interface that eliminates the need for external "glue logic". The no "glue logic" concept provides a user-programmable interface to a variety of 8- and 16-bit (multiplexed or non-multiplexed) microcontrollers that is easy to use. The part's integration, small form factor, low power consumption, and ease of use make it the ideal part for interfacing to virtually any microcontroller. The PSD4XX provides two Zero-power PLDs (ZPLD): a Decode PLD (DPLD) and a General-purpose PLD (GPLD). A configuration bit (Turbo) can be set by the MCU, and will automatically place the ZPLDs into Standby Mode if no inputs are changing. The ZPLDs are designed to consume minimum power using Zero-power CMOS technology that uses only 10 A (typical) standby current. Unused product terms are automatically disabled, also reducing power, regardless of the Turbo bit setting. The main function of the DPLD is to perform address decoding for the internal I/O ports, EPROM, and SRAM. The address decoding can be based on up to 24 bits of address inputs, control signals (RD, WR, PSEN, etc.), and internal page logic. The DPLD supports separate program and data spaces (for 8031 compatible MCUs). The General-purpose PLD (GPLD) can be used to implement various logic functions defined by the user, such as: * State machines * Loadable counters and shift registers * Inter-processor mailbox * External control logic (chip selects, output enables, etc.). The GPLD has access to up to 59 inputs, 118 product terms, 24 macrocells, and 24 I/O pins. 1 PSD4XX Family 1.0 Introduction (cont.) The PSD4XX has 40 I/O pins that are divided among 5 ports. Each I/O pin can be individually configured to provide many functions, including the following: * MCU I/O * GPLD I/O * Latched address output (for MCUs with multiplexed data bus) * Data bus (for MCUs with non-multiplexed data bus). The PSD4XX can easily interface with virtually any 8- or 16-bit microcontroller with a multiplexed or non-multiplexed bus. All of the MCU control signals are connected to the ZPLDs, enabling the user to generate signals for external devices. The PSD4XX provides between 256 Kbits and 1 Mbit of EPROM that is divided in to four equal-sized blocks. Each block can occupy a different address location, allowing for versatile address mapping. The access time of the EPROM includes the address latching and DPLD decoding. The PSD4XX has an optional 16 Kbit SRAM that can be battery-backed by connecting a battery to the Vstby pin. The battery will protect the contents of the SRAM in the event of a power failure. Therefore, you can place data in the SRAM that you want to keep after the power is switched off. Power switchover to the battery automatically occurs when VCC drops below Vstby. A four-bit Page Register enables easy access to the I/O section, EPROM, and SRAM for microcontrollers with limited address space. The Page Register outputs are connected to both ZPLDs and thus can also be used for external paging schemes. The Power Management Unit (PMU) of the PSD4XX enables the user to control the power consumption on selected functional blocks, based on system requirements. For microcontrollers that do not generate a chip select input for the PSD, the Automatic Power-Down (APD) unit of the PMU can be setup to enable the PSD to enter Power Down Mode or Sleep Mode, based on the inactivity of ALE (or AS). Implementing your design has never been easier than with PSDsoft--ST's software development suite. Using PSDsoft, you can do the following: * Configure your PSD4XX to work with virtually any microcontroller * Specify what you want implemented in the programmable logic using a design file * Simulate your design * Download your design to the part using a programmer. 2.0 Key Features Single-chip programmable peripheral for microcontroller-based applications 256K to 1 Mbit of UV EPROM with the following features: * Configurable as 32, 64, or 128 K x 8; or as 16, 32, or 64 K x 16 * Divided into four equally-sized mappable blocks for optimized address mapping * As fast as 70 ns access time, which includes address decoding * Built-in Zero-power technology 16 Kbit SRAM is configurable as 2K x 8 or 1K x 16. The access time can be as quick as 70 ns, including address decoding. The contents of the SRAM can be battery-backed by connecting a battery to the Vstby pin. The SRAM also has built-in Zero-power technology. 40 I/O pins (divided into five 8-bit ports) that can be individually configured for: * Standard MCU I/O * PLD/macrocell I/O * Latched address output * High-order address inputs * Special function I/O * Open-drain output 2 PSD4XX Family 2.0 Key Features Two Zero-power Programmable Logic Devices (ZPLDs): the Decode PLD (DPLD) and the General-purpose PLD (GPLD) can be used for: * Up to 59 Input and 126 output product terms * 24 Macrocells and I/O * Decode up to 16 MB of address * State machines and state logic * Generate external signals (chip selects, bus interface, etc.) Microcontroller logic that eliminates the need for external "glue logic" has the following features: * Ability to interface to multiplexed and non-multiplexed buses * Built-in address latches for multiplexed address/data bus * ALE and Reset polarity are programmable * Multiple configurations are possible for interface to many different microcontrollers Page logic is connected to the ZPLDs and expands the MCU address space to up to 16 times Programmable power management allows: * SRAM, EPROM, and ZPLDs to enter standby mode automatically * Disabling of the clock input to the ZPLDs * ZPLDs to enter a special low power mode (Sleep Mode), based on Turbo bit setting A security bit prevents reading the PSD4XX configuration and the ZPLD contents. Setting this bit will prevent the device from being copied on a device programmer. Built-in security enables the user to block read accesses from a device programmer Package choices include 68-pin PLCC, 68-pin CLDCC, and 80-pin TQFP Programmable polarity Reset output (includes hysteresis), based on Reset input Simple, menu-driven software (PSDsoft) allows configuration and design entry on a PC. 3.0 Notation Throughout this data sheet, references are made to the PSD4XX. In most cases, these references also cover the ZPSD4XX and ZPSD4XXV products. Exceptions will be noted. The main difference between the ZPSD4XX and the PSD4XX is the standby current (Isb). The ZPSD4XX devices have been rated for a lower standby current. Also, there is no low-voltage version of the PSD4XX. There is only the low-voltage version of the ZPSD4XX, which has a V suffix. 4.0 Zero-Power Background Portable and battery powered systems have recently become major embedded control application segments. As a result, the demand for electronic components having extremely low power consumption has increased dramatically. Recognizing this need, ST has developed a new Zero Power technology. PSD4XX products virtually eliminate the DC component of power consumption reducing it to standby levels. Eliminating the DC component is the basis for the words "Zero Power". PSD4XX products also minimize the AC power component when the chip is changing states. The result is a programmable microcontroller peripheral family that replaces discrete circuit functions while drawing minimal current. 3 ZPLD INPUT BUS PAGE REG. CONTROL RD, WR PROG.

PSD4XX Block Diagram 4 ADDRESS/DATA/CONTROL BUS PSD4XX Family 5.0 Integrated Power Management TM Operation Upon each address or logic input change to the ZPSD, the device powers up from low power standby for a short time. Then the ZPSD consumes only the necessary power to deliver new logic or memory data to its outputs as a response to the input change. After the new outputs are stable, the ZPSD latches them and automatically reverts back to standby mode. The ICC current flowing during standby mode and during DC operation is identical and is only a few microamperes. The ZPSD automatically reduces its DC current drain to these low levels and does not require controlling by the CSI (Chip Select Input). Disabling the CSI pin unconditionally forces the ZPSD to standby mode independent of other input transitions. The only significant power consumption in the ZPSD occurs during AC operation. The ZPSD contains the first architecture to apply zero power techniques to memory and logic blocks. Figure 2 compares ZPSD Zero-power operation to the operation of a discrete solution. A standard microcontroller (MCU) bus cycle usually starts with an ALE (or AS) pulse and the generation of an address. The ZPSD detects the address transition and powers up for a short time. The ZPSD then latches the outputs of the PAD, EPROM and SRAM to the new values. After finishing these operations, the ZPSD shuts off its internal power, entering standby mode. The time taken for the entire cycle is less than the ZPSD's "access time." The ZPSD will stay in standby mode if inputs do not change between bus cycles. In an alternate system implementation using discrete EPROM, SRAM, and other discrete components, the system will consume operating power during the entire bus cycle. This is because the chip select inputs on the memory devices are usually active throughout the entire cycle. The AC power consumption of the ZPLD may be calculated using the composite frequency of the MCU address and control signals, as well as any other logic inputs to the ZPLD. NOTE: The ZPSD4XX is rated for lower standby current (ISB) than the PSD4XX. Figure 2.

PSDsoft--ST's software development suite--is used throughout the design phase. You start with a design file that is written in PSDabel--a high-level hardware description language (HDL). Before you compile your design, you must also configure the PSD4XX so it knows what signals to expect from your microprocessor and what pre-runtime options should be set (such as the security bit). Once you have a design file and have configured the device, you are ready to run the Fitter and Address Translator. The Fitter accepts input from PSDabel and PSD Configuration, synthesizes this user logic and configuration, and fits the design to the PSD silicon. The Address Translator process allows the user to map the MCU firmware from a crosscompiler (in Intel HEX or S-Record format) into the NVM memory blocks within the PSD. As a result, the MCU firmware is merged with the logic and configuration definition of the PSD. The output of the Address Translator and the Fitter is the required object file that is used by a programmer to program the PSD device. The object file includes chip configuration, the PLD fusemap, and MCU firmware information. PSDsilosIII is an optional program that provides functional chip-level simulation of the PSD4XX. PSDsoft automatically creates files for input to the simulator. These files convey relevant design information to the simulator. As a result, the user only has to create a stimulus file since all of the signals and node names are taken from the design file. Figure 3.

Many of the blocks perform multiple functions, and are user configurable. The chip configurations are specified by the user in the PSDsoft Development Software. Other configurations are specified by setting up the appropriate bits in the configuration registers during run time. 9.1 The ZPLD Block The PSD4XX series devices provide two ZPLD configurations. The ZPLD in the PSD4XXA1 devices has 8 registered macrocells, 8 combinatorial macrocells, and up to 113 product terms. The PSD4XXA2 has a full function ZPLD with 24 registered macrocells and up to 126 product terms. 9.1.1 The PSD4XXA1 ZPLD Block Key Features 2 Embedded ZPLD devices 8 registered and 8 combinatorial macrocells Combinatorial/registered outputs Maximum 113 product terms Programmable output polarity User configured register clear/preset User configured register clock input 37 Inputs Accessible via 16 I/O pins Power Saving Mode UV-Erasable General Description The ZPLD block has 2 embedded PLD devices: DPLD The Address Decoding PLD, generating select signals to internal I/O or memory blocks. GPLD The General Purpose PLD provides 8 registered and combinatorial programmable macrocells for general or complex logic implementation; dedicated to user application. Figure 4 shows the architecture of the ZPLD. The PLD devices all share the same input bus. The true or complement of the 37 input signals are fed to the programmable AND-ARRAY. Names and sources of the input signals are shown in Table 3. The PB signals, depending on user configuration, can either be macrocell feedbacks or inputs from Port B. 10 CLKIN RESET WR/R_W RD/E/DS PE1 (PSEN/BHE) PE0 (ALE/AS) CSI PMU A8 - A15 ADIO PORT A0, A1 PGR0 - 3 PAGE REG.

As shown in Figure 4, the DPLD consists of a large programmable AND ARRAY. There are a total of 37 inputs and 8 outputs. Each output consists of a single product term. Although the user can generate select signals from any of the inputs, the select signals are typically a function of the address and Page Register inputs. The select signals are defined by the user in the ABEL file (PSDabel). The address line inputs to the DPLD include A0, A1 and A8 - A15. If more address lines are needed, the user can bring in the lines through Port A to the DPLD. 12 PSD4XX Family 9.0 The PSD4XX Architecture (cont.) 9.1.1.2 The GPLD The structure of the General Purpose PLD consists of a programmable AND ARRAY and 2 sets of I/O Macrocells. The ARRAY has 37 input signals, same as the DPLD. From these inputs, "ANDed" functions are generated as product term inputs to the macrocells. The I/O Macrocell sets are named after the I/O Ports they are linked to, e.g., the macrocells connected to Port B are named PB Macrocells. The PB macrocells are registered macrocells with D-type flip-flops, where PA consists of combinatorial macrocells. 9.1.1.3 TPA Macrocell Structure Figure 5 shows the PA Macrocell block, which consists of 8 identical combinatorial macrocells. Each macrocell output can be connected to its own I/O pin on Port A.

Each macrocell output can be connected to its own I/O pin on Port B. The two inputs, CLKIN and MACRO-RST, are used as clock and clear inputs to all the macrocells. The CLKIN comes directly from the CLKIN input pin. The MACRO-RST is the same as the Reset input pin except it is user configurable. The circuit of a PB Macrocell is shown in Figure 8. There are 10 product terms from the GPLDs AND ARRAY as inputs to the macrocell. Users can select the polarity of the output, and configure the macrocell to operate as: Registered Output Select output from D flip flop. Combinatorial Output Select output from OR gate. GPLD Input Use Port B pin as dedicated input. GPLD Output Use Port B pin as dedicated output. GPLD I/O Use Port B pin as bidirectional pin. Macrocell Feedback Register feedback for state machine implementations or expander feedback from the combinatorial output, to possibly expand the number of product terms available to another macrocell. In case of "Buried Feedback", where the output of the macrocell is not connected to a Port B pin, Port B can be configured to perform other user defined I/O functions. Each D flip flop in the macrocells has its own dedicated asynchronous clear, preset and clock input. The signals are defined as follow: PRESET Active only if defined by a product term (PBi.PR) CLEAR Two selectable inputs: Reset input and/or user defined product term (PBi.RE) CLK Two selectable inputs - CLKIN input or user defined product term (PBi.CLK). The macrocell is operated in Synchronous Mode if the clock input is CLKIN, and is in Asynchronous Mode if the clock is a product-term clock defined by the user. Figure 9 shows the input/output path of a PB macrocell to the Port pin with which it is associated. If the Port pin is specified as a PB output pin in the PSDsoft, the MUX in the I/O Port Cell selects the PB Macrocell as an output of the Port pin. The output enable signal to the buffer in the I/O cell can be controlled by a product term from the AND Array. If the Port pin is specified as a ZPLD input pin, the MUX in the PB Macrocell selects the Port input signal to be one of the 61 signals in the ZPLD Input Bus. 17 PSD4XX Family 9.0 The PSD4XX Architecture (cont.) 9.1.1.5 The ZPLD Power Management The ZPLD implements a Zero Power Mode, which provides considerable power savings for low to medium frequency operations. To enable this feature, the ZPLD Turbo bit in the Power Management Mode Register 0 (PMMR0) has to be turned off. If none of the inputs to the ZPLD are switching for a time period of 90ns, the ZPLD puts itself into Zero Power Mode and the current consumption is minimal. The ZPLD will resume normal operation as soon as one or more of the inputs change state. Two other features of the ZPLD provide additional power savings: 1. Clock Disable: Users can disable the clock input to the ZPLD and/or macrocells,thereby reducing AC power consumption. 2. Product Term Disable: Unused product terms in the ZPLD are disabled by the PSDsoft Software automatically for further power savings. The ZPLD power configuration is described in the Power Management Unit section. 18 AND ARRAY MACRO - RST CLKIN PB7 PB7 .PR PB7 .RE PB7 .OE PB7 .CLK PTB7 - [0 . . 5] PB1 PB1 .PR PB1 .RE PB1 .OE PB1 .CLK PTB1 - [0 . . 5] PB0 PB0 .PR PB0 .RE PB0 .OE PB0 .CLK PTB0 - [0 . . 5] MC7 MC1 MC0 PB MACROCELL PB7- INPUT MACRO .OUT PB7 .OE PB1-INPUT MACRO .OUT PB1 .OE PB0 - INPUT MACRO .OUT PB0 .OE PB7 PB1 PB0 PORT B I/O CELLS 9.0 The PSD4XX Architecture ZPLD BUS PSD4XX Family Figure 8.

The PLD devices all share the same input bus. The true or complement of the 59 input signals are fed to the programmable AND-ARRAY. Names and source of the input signals are shown in Table 4.

As shown in Figure 12, the DPLD consists of a large programmable AND ARRAY. There are a total of 59 inputs and 8 outputs. Each output consists of a single product term. Although the user can generate select signals from any of the inputs, the select signals are typically a function of the address and Page Register inputs. The select signals are defined by the user in the ABEL file (PSDabel). The address line inputs to the DPLD include A0, A1 and A8 - A15. If more address lines are needed, the user can bring in the lines through Port A to the DPLD. 24 (1) (1) (3) (10) (4) (8) (8) (8) WR/R_W RD/E/DS RESET DPLD INPUTS : 59 DPLD OUTPUTS : 8 CSI, CLKIN A8 - A15, A0, A1 PGR0 - PGR3 PD0 - PD7 PC0 - PC7 PE0 - PE7 PB0 - PB7 PA0 - PA7 PSEL1 PSEL0 CSIOP RS0 ES3 ES2 ES1 PERIPHERAL I /O SELECTS I /O DECODER SELECT RAM SELECT 4 EPROM BLOCK SELECTS (cont.)

DPLD Logic Array 25 PSD4XX Family The PSD4XX Architecture (cont.) 9.1.2.2 The GPLD The structure of the General Purpose PLD consists of a programmable AND ARRAY and 3 sets of I/O Macrocells. The ARRAY has 59 input signals, same as the DPLD. From these inputs, "ANDed" functions are generated as product term inputs to the macrocells. The I/O Macrocell sets are named after the I/O Ports they are linked to, e.g., the macrocells connected to Port A are named PA Macrocells. The 3 sets of macrocells, PA, PB and PE, are similar in structure and function. Figure 13 shows the output/input path of a GPLD macrocell to the Port pin with which it is associated. If the Port pin is specified as a GPLD output pin in PSDsoft, the MUX in the I/O Port Cell selects the GPLD macrocell as an output of the Port pin. The output enable signal to the buffer in the I/O cell can be controlled by a product term from the AND ARRAY. If the Port pin is specified as a ZPLD input pin, the MUX in the GPLD macrocell selects the Port input signal to be one of the 61 signals in the ZPLD Input Bus. 9.1.2.3 Port A Macrocell Structure Figure 14 shows the PA Macrocell block, which consists of 8 identical macrocells. Each macrocell output can be connected to its own I/O pin on Port A. There are 3 user programmable global product terms output from the GPLD's AND ARRAY which are shared by all the macrocells in Port A: PA.OE Enable or tri-state Port A output pins PA.PR Preset D flip flop in the macrocells PA.RE Reset/Clear D flip flop in the macrocells Two other inputs, CLKIN and MACRO-RST, are used as clock and clear inputs to the D flip flop. The CLKIN comes directly from the CLKIN input pin. The MACRO-RST is the same as the Reset input pin except it is user configurable. The circuit of a PA Macrocell is shown in Figure 15. There are 6 product terms from the GPLD's AND ARRAY as inputs to the macrocell. Users can select the polarity of the output, and configure the macrocell to operate as: Registered Output Select output from D flip flop Combinatorial Output Select output from OR gate GPLD Input Use Port A pin as dedicated input GPLD Output Use Port A pin as dedicated output GPLD I/O Use Port A pin as bidirectional pin Macrocell Feedback Register feedback for state machine implementations or expander feedback from the combinatorial output, to expand the number of product terms available to another macrocell. In case of "Buried Feedback", where the output of the macrocell is not connected to a Port A pin, Port A can be configured to perform other user defined I/O functions. The two global product terms assigned for asynchronous clear (PA.RE) and preset (PA.PR) are mainly for proper PA Macrocell initialization. The macrocell flip-flop can also be cleared during reset by MACRO-RST, if such an option is chosen. The clock source is always the input clock CLKIN. 26 ZPLD INPUT BUS GLOBAL CLOCK MACRO_RST PT CLOCK PT CLEAR PTs PT RESET MUX CLK SELECT POLARITY SELECT PT OUTPUT ENABLE (OE) AND ARRAY PT GPLD MACROCELL D CK CL PR Q PORT INPUT PSD4XX FIG. 18 MUX MUX MACROCELL OUTPUT COMB./REG.

The CLKIN comes directly from the CLKIN input pin. The MACRO-RST is the same as the Reset input pin except it is user configurable. The circuit of a PB Macrocell is shown in Figure 17. There are 10 product terms from the GPLD's AND ARRAY as inputs to the macrocell.

If pins PE0 and PE1 are used as bus control signal inputs (ALE, PSEN/BHE), the corresponding macrocells' feedbacks are disabled. The bus control signals are connected to the ZPLD Input Bus. The two global product terms assigned for asynchronous clear (PE.RE) and preset (PE.PR) are for proper PE Macrocell initialization. The macrocell flip-flop can also be cleared during reset by MACRO-RST as an option.

The type of bus interface is specified by the user in the PSDsoft software (PSD configuration). The bus control input pins have multi-function capabilities. By choosing the right configuration, the PSD4XX is able to interface to most microcontrollers, including the ones listed in Table 5. In Table 6, the names of the bus control input signal pins and their multiple functions are shown. For example, Pin PE0 can be configured by the PSD configuration software to perform any one of the five functions. Examples on the interface between the PSD4XX and some typical microcontrollers are shown in following sections. 37 PSD4XX Family The PSD4XX Architecture (cont.) Table 6.

The ADIO port of the PSD4XX is connected directly to the microcontroller address/data bus (AD0-AD15 for 16 bit bus). The ALE input signal latches the address lines internally. In a read bus cycle, data is driven out through the ADIO Port transceivers after the specified access time. The internal ADIO Port connection for a 16 bit multiplexed bus is shown in Figure 21. The ADIO Port is in tri-state mode if none of the PSD4XX internal devices are selected. 9.2.3 PSD4XX Interface To Non-Multiplexed Bus Figure 22 shows a PSD4XX interfacing to a microcontroller with a non-multiplexed address/data bus. The address bus is connected to the ADIO Port, and the data bus is connected to Port C and/or Port D, depending on the bus width. There is no need for the ADIO Port to latch the address internally, but the user is offered the option to do so in the PSD4XX PSDsoft Software. The data Ports are in tri-state mode when the PSD4XX is not accessed by the microcontroller. 38 MICROCONTROLLER ALE BHE PORT E CSI RST RD WR PORT B PORT A (OPTIONAL) PORT D A - [15 : 8] (OPTIONAL) A - [ 7:0] A - [15 : 8] ADIO PORT PORT C AD - [15 : 8] AD - [7:0] The PSD4XX Architecture PSD4XX PSD4XX Family Figure 20.

Address In Port A can be configured as high order address (A16-A23) inputs to the ZPLD for EPROM or other decoding. Inputs are latched by ALE/AS if Multiplexed Bus is selected. Other Ports can be configured as address input ports for the ZPLD. These inputs should not be used for EPROM decoding and are not latched internally. 2. Address Out For multiplexed bus only. Latched address lines A0-A15 are available on Port A, B, C or D. Details on the optional features are described in the I/O Port section. 9.2.6 Bus Interface Examples The next four figures show the PSD4XX interfacing with some popular microcontrollers. The examples show only the basic bus connections; some of the pin names on the PSD4XX parts change to reflect the actual pin functions. Figure 23 shows the interface to the 80C31. The 80C31 has a 16 bit address bus and an 8-bit data bus. The lower address byte is multiplexed with the data bus. The RD and WR signals are used for accessing the data memory (SRAM) and the PSEN signal is for reading program memory (EPROM). The ALE signal is active high and is used to latch the address internally. Port C provides latched address outputs A[7:0]. Ports A, B, D, and E (PE2-PE7) can be configured to perform other functions. The RSTOUT reset to the 80C31 is generated by the ZPLD from the RESET input. This configuration eliminates any reset race condition between the 80C31 and the PSD4XX. Figure 24 shows the 68HC11 interface, which is similar to the 80C31 except the PSD4XX generates internal RD and WR from the 68HC11's E and R/W signals. In Figure 25, the Intel 80C196 microcontroller is interfaced to the PSD4XX. The 80C196 has a multiplexed 16-bit address and data bus. The BHE signal is used for data byte selection. Ports C and D are used as output ports for latched address A[15:0]. Pins PE6 and PE7 can be programmed as ZPLD outputs to provide the READY and BUSWIDTH control signals to the 80C196.

Interfacing PSD4XX With Motorola 68331 47 PSD4XX Family The PSD4XX Architecture (cont.) 9.3 I/O Ports There are 5 programmable 8-bit I/O ports: Port A, Port B, Port C, Port D and Port E. These ports all have multiple operating modes, depending on the configuration. Some of the basic functions are providing input/output for the ZPLD, or can be used for standard I/O. Each port pin is individually configurable, thus enabling a single 8-bit port to perform multiple functions. The I/O ports occupy 256 bytes of memory space as defined by "CSIOP". Refer to the System Configuration section for I/O register address offset. To set up the port configuration the user is required to: 1. Define I/O Port Chip Select (CSIOP) in the ABEL file. 2. Initialize certain port configuration registers in the user's program and/or 3. Specify the configuration in the PSD4XX PSDsoft Software. 4. Unused input pins should be tied to VCC or GND. The following is a description of the operating modes of the I/O ports. The functions of the port registers are described in later sections. 9.3.1 Standard MCU I/O The Standard MCU I/O Mode provides additional I/O capability to the microcontroller. In this mode, the ports can perform standard I/O functions such as sensing or controlling various external I/O devices. Operation options of this mode are as follows: Configuration 1. Declare pins or signals which are used as I/O in the ABEL file. 2. Set the bit or bits in the Control Register to "1". 3. As Output Port - Write output data to Data Out Register - Set Direction Register to output mode 4. As Input Port - Set Direction Register to input mode - Read input from Data In Register The port remains an output or input port as long as the Direction Register is not changed. 9.3.2 PLD I/O The PLD I/O mode enables the port to be configured as an input to the ZPLD, or as an output from the GPLD macrocell. The output can be tri-stated with a control signal defined by a product term from the ZPLD. This mode is configured by the user in the PSD4XX PSDsoft Software, and is enabled upon power up. For a detailed description, see the section on the ZPLD. Configuration 1. Declare pins or signals in the ABEL file (PSDsoft). 2. Write logic equations in the ABEL file. 3. PSD Compiler maps the PLD functions to the PSD. 48 PSD4XX Family The PSD4XX Architecture (cont.) 9.3.3 Address Out For microcontrollers with a multiplexed address/data bus, the I/O ports in Address-Out mode are able to provide latched address outputs (A0 - A15) to external devices. This mode of operation requires the user to: Configuration 1. Declare the pins used as address line outputs in the ABEL file (PSDsoft). 2. Write "0" to the corresponding bit in the Control Register associated with each I/O port. 3. Set the Direction Register to Output Mode. 9.3.4 Address In There are two Address In modes: 1. For Port A - as other address line (A2-A7 and A16-A23) inputs to the DPLD. Additional address inputs included in the EPROM decoding must come from Port A. The address inputs are latched internally by ALE/AS if Multiplexed Bus is specified in PSDsoft. 2. For Ports C and D - as address inputs to the ZPLD for general decoding, should not be used in EPROM decoding. Configuration 1. Declare pins or signals used as Address In in the ABEL file (PSDsoft). 2. Write latch equations in the .ABL file, e.g., A16.LE = ALE. 3. Include latched address in logic equations. 9.3.5 Data Port In this mode, the port is acting as a data bus port for a microcontroller which has a non-multiplexed address/data bus. The Data Port is connected to the data bus of the microcontroller and the ADIO port is connected to the address bus. Configuration Select the non-multiplexed bus option in PSD configuration (PSDsoft). 9.3.6 Alternate Function In This mode is per-pin configurable and enables the user to define pin PE7 of Port E as Automatic Power Down (APD) CLK input. Configuration 1. Select input functions in PSD configuration. 2. PSD Compiler assigns pins for the selected options. 49 PSD4XX Family The PSD4XX Architecture (cont.) 9.3.7 Peripheral I/O This mode enables the microcontroller to read or write to a peripheral though Port A. When there is no read/write operation, Port A is tri-stated. One of the applications of Peripheral I/O is in a DMA based design. Configuration 1. Declare the pins used as pheripheral I/O in the ABEL file. 2. Write logic equations for PSEL0 and PSEL1. 3. Write a "1" to the PIO bit in the VM Register to activate the Peripheral I/O operation. See the section on Peripheral I/O for a detailed description. 9.3.8 Open Drain Outputs This mode enables the user to configure Ports C and D pins as open drain outputs. CMOS output is the default configuration. Writing "1" to the corresponding bit in the Open Drain Register changes the pin to open drain output. Table 12. Operating Modes of the I/O Ports Table 12 summarizes the operating modes of the I/O ports. Not all the functions are available to every port.

Cannot be latched by ALE 50 Yes Yes PSD4XX Family The PSD4XX Architecture (cont.) 9.3.9 Port Registers There are two sets of registers per I/O port: the Port Configuration Registers (PCR) which consist of four 8-bit registers; and the Port Data Registers (PDR) which include three 8-bit registers. The PCR is used for setting up the port configuration, while the PDR enables the microcontroller to write or read port data or status bits. Tables 13 and 14 show the names and the registers and the ports to which they belong. All the registers in the PCR and PDR are 8-bits wide and each bit is associated with a pin in the I/O port. In Table 15, the LSB of the Data In Register of Port A is connected to pin PA0, and the MSB is connected to PA7. This pin configuration also applies to other registers and ports. For example, in the Direction Register of Port A, writing a hex value of 07 to the register configures pins PA0 - PA2 as output pins, while PA3 - PA7 remain as input pins. Registers can be accessed by the microcontroller during normal read/write bus cycles. The I/O address offset of the registers are listed in the System Configuration section. Table 13.

For setting a Standard MCU I/O Mode, a "1" must be written to the corresponding bit in the register. Writing a "0" to the register is required for the Address Out mode. The register has a default value of "0" after reset. 9.3.9.2 Direction Register This register is used to control the direction of data flow in the I/O Ports. Writing a "1" to the corresponding bit in the register configures the port to be an output port, and a "0" forces the port to be an input port. The I/O configuration of the port pins can be determined by reading the Direction Register. After reset, the pins are in input mode. 9.3.9.3 Open Drain This register determines whether the output pin driver of Ports C or D is a CMOS driver or an Open Drain driver. Writing a "0" to the register selects a CMOS driver, while a "1" selects an Open Drain driver. 9.3.9.4 PLD - I/O Register This is a read only status register. Reading a "1" indicates the corresponding pin is configured as a PLD pin. A "0" indicates the pin is an I/O pin. 9.3.9.5 Data In Register This register is used in the Standard MCU I/O Mode configuration to read the input pins. 9.3.9.6 Data Out Register This register holds the output data in the Standard MCU I/O Mode. The contents of the register can also be read. 9.3.9.7 Macrocell Out Register This register enables the user to read the outputs of the GPLD macrocell (PA, PB, and PE macrocells). 9.3.9.8 I/O Register Address Offset The I/O Register can be accessed by the microcontroller during normal read/write bus cycles. The address of a register is defined as: CSIOP + register address offset The CSIOP is the base address that is defined in the ABEL file and occupies a 256 byte space. The register address offset lies within this 256 byte space. Tables 16 and 16a are the address offset of the registers. 52 PSD4XX Family The PSD4XX Architecture (cont.) Table 16.

It can be configured to perform one or more of the following functions: Standard MCU I/O Mode PLD I/O Address Out - latched address lines A[0-7] are assigned to pins PA[0-7]. Address In - input port for other address lines, inputs can be latched by ALE. Peripheral I/O Figure 27 shows the structure of a Port A pin. If the pin is configured as an output port, the multiplexer selects one of its three inputs as output. If the pin is configured as an input, the input connects to : 1. Data In Register as input in Standard MCU I/O Mode or 2. PA Macrocell as PLD input or 3. PA Macrocell through a latch latched by ALE, as Address In input. 9.3.11 Port B - Functionality and Structure Port B is similar to Port A in structure. It can be configured to perform one or more of the following functions: Standard MCU I/O Mode PLD I/O Address Out - address lines A[0-7] for 8-bit multiplexed bus or address lines A[8-15] for 16-bit multiplexed bus are assigned to pins PB[0-7]. Figure 28 shows the structure of a Port B pin. If the pin is configured as an output port, the multiplexer selects one of its three inputs as output. If the pin is configured as input, the input connects to : Data In Register as input in Standard MCU I/O Mode or PB Macrocell as PLD input 54 INTERNAL ADDRESS / DATA BUS G D WR ALE PA . OE Q Q DIR.

Port E Pin Structure (cont.) PSD4XX Family The PSD4XX Architecture (cont.) 9.4 Memory Block The PSD4XX provides EPROM memory for code storage and SRAM memory for scratch pad usage. Chip selects for the memory blocks come from the DPLD decoding logic and are defined by the user in the PSDsoft Software. Figure 32 shows the organization of the Memory Block. The PSD4XX family uses Zero-power memory techniques that place memory into Standby Mode between MCU accesses. The memory becomes active briefly after an address transition, then delivers new data to the outputs, latches the outputs, and returns to standby. This is done automatically and the designer has to do nothing special to benefit from this feature. Both the EPROM and SRAM have this feature. 9.4.1 EPROM The PSD4XX provides three EPROM densities: 256Kbit, 512Kbit, or 1Mbit. The EPROM is divided into four 8K, 16K or 32K byte blocks. Each block has its own chip select signals (ES0 - ES3). The EPROM can be configured as 32K x 8, 64K x 8 or 128K x 8 for microcontrollers with an 8-bit data bus. For 16-bit data buses, the EPROM is configured as 16K x 16, 32K x 16 or 64K x 16. 9.4.2 SRAM The SRAM has 16Kbits of memory, organized as 2K x 8 or 1K x 16. The SRAM is enabled by chip select signal RS0 from the DPLD. The SRAM has a battery back-up (STBY) mode. This back-up mode is invoked when the VCC voltage drops under the Vstdby voltage by approximately 0.7 V. The Vstdby voltage is connected only to the SRAM and cannot be lower than 2.7 volts. 9.4.3 Memory Select Map The EPROM and SRAM chip select equations are defined in the ABEL file in terms of address and other DPLD inputs. The memory space for the EPROM chip select (ES0 - ES3) should not be larger than the EPROM block (8KB, 16KB, or 32KB) it is selecting. The following rules govern how the internal PSD4XX memory selects/space are defined: The EPROM blocks address space cannot overlap SRAM, internal I/O and Peripheral I/O space cannot overlap SRAM, internal I/O and Peripheral I/O space can overlap EPROM space, with priority given to SRAM or I/O. The portion of EPROM which is overlapped cannot be accessed. The Peripheral I/O space refers to memory space occupied by peripherals when Port A is configured in the Peripheral I/O Mode. 61 PSD4XX Family The PSD4XX Architecture (cont.) 9.4.4 Memory Select Map For 8031 Application The 8031 family of microcontrollers has separate code memory space and data memory space. This feature requires a different Memory Select Map. Two modes of operation are provided for 8031 applications. The selection of the modes is specified in the PSD4XX PSDsoft Software (PSDconfiguration): Separate Space Mode In this mode, the PSEN signal is used to access code from EPROM, and the RD signal is used to access data from SRAM. The code memory space is separated from the data memory space. Combined Space Mode In this mode, the EPROM can be accessed by PSEN or RD. The EPROM is used for code and data storage. The memory block's address space cannot overlap. If data and code memory blocks must overlap each other, the RD signal can be included as an additional address input in generating the EPROM chip select signals (ES0 - ES3). In this case the EPROM access time is from the RD valid to data valid. Figures 32a and 32b show the memory configuration in the two modes. In some applications it is desirable to execute program codes in SRAM. The PSD4XX provides this option by enabling PSEN to access SRAM. To activate this option, the SRCODE bit of the VM Register must be set to "1" (see Table 17). SRAM space can overlap EPROM space and has priority when PSEN is used. Table 17.

In this mode, Port A is connected to the data bus of peripheral devices. Port A is enabled only when the microcontroller is accessing the devices, otherwise the Port is tri-stated. This feature enables the microcontroller to access external devices without requiring buffers and decoders. Figure 34 shows the structure of Port A in the Peripheral I/O Mode. The memory address space occupied by the devices are defined by two signals: PSEL0 and PSEL1. The signals are direct outputs from the Decoding PLD (DPLD). Whenever any of the signals is active, the Port A driver is enabled, and the direction of the data flow is determined by the RD/WR signals. The Peripheral I/O Mode and the peripheral select signals are configured and defined in the PSDsoft Software (see the section on I/O Port for configuration). The PIO bit in the VM Register (see Table 17) also needs to be set to "1" by the user to initialize the Peripheral I/O Mode. The Peripheral I/O mode can be used, for example, in DMA applications where the microcontroller does not support DMA operations, such as tri-stating the address/data bus. Figure 35 shows a block diagram of a microcontroller and PSD4XX based design that makes use of this mode. In this application, the microcontroller has a multiplexed bus which is connected to the ADIO port. The C and D ports connect to the peripheral address bus and are both configured in Address Out Mode. Port A is configured in the Peripheral I/O mode and is connected to the peripheral data bus. Ports B and E are used to generate control signals. During normal activity, the microcontroller has access to any peripheral (memory or I/O device) through the PSD4XX device. When there is a DMA request, the microcontroller tri-states the address bus on Ports C and D by writing a "0" to the port Direction Registers. The DMA controller then takes over the data and address buses after receiving acknowledgement from the microcontroller. Figure 34.

PSD4XX Peripheral I/O Configuration (cont.) PSD4XX Family The PSD4XX Architecture (cont.) 9.5 Power Management Unit The PSD4XX provides many power saving options. By configuring the PMMRs (Power Management Mode Registers), the user can reduce power consumption. Table 18 shows the bit configuration of the PMMR0 and PMMR1. The microcontroller is able to control the power consumption by changing the PMMR bits at run time. 9.5.1 Standby Mode There are two Standby Modes in the PSD4XX: Power Down Mode Sleep Mode 9.5.1.1 Power Down Mode In this mode, the internal devices are shut down except for the I/O ports and the ZPLD. There are three ways the PSD4XX can enter into the Power Down Mode: by controlling the CSI input, by activating the Automatic Power Down (APD) Logic and the ZPLD, or when none of the inputs are changing and the Turbo bit is off. The CSI The CSI input pin is an active low signal. When low, the signal selects and enables the PSD4XX. The PSD4XX enters into Power Down Mode immediately when the signal turns high. This signal can be controlled by the microcontrollers, external logic or it can be grounded. The CSI input turns off the internal bus buffers in Standby Mode. The address and control signals from the microcontroller are blocked from entering the ZPLD as inputs. The APD Logic The APD unit enables the user to enter a power down mode independent of controlling the CSI input. This feature eliminates the need for external logic (decoders and latches) to power down the PSD. The APD unit concept is based on tracking the activity on the ALE pin. If the APD unit is enabled and ALE is not active, the 4-bit APD counter starts counting and will overflow after 15 clocks, generating a PD (Power Down) signal powering down the PSD. If sleep mode is enabled, then PD signal will also activate the sleep mode. Immediately after ALE starts pulsing the PSD will get out of the power down or sleep mode. The operation of APD is controlled by the PMMR (see Figure 36a). PMMR1 bit 0 selects the source of the APD counter clock. After reset the APD counter clock is connected to PE7 (APD CLK) on the PSD. In order to guarantee that the APD will not overflow there should be less than 15 APD clocks between two ALE pulses. If CLKIN frequency is adequate, then it can be connected to the APD and PE7 is used for other functions. The next step is to select the ALE power down polarity. Usually, MCUs entering power down will freeze their ALE at logic high or low. By programming bit 1 of PMMR0 the power down polarity can be defined for the APD. If the APD detects that the ALE is in the power down polarity for 15 APD counter clocks then the PSD will enter a power down mode. To enable the APD operation, bit 2 in the PMMR0 should be set high. 9.5.1.2 Sleep Mode The Sleep Mode is activated if the SLEEP EN bit, the APD EN bit, and the ALE Polarity bit in the PMMR are set, and the APD Counter has overflowed after 15 clocks (see Figure 36). In Sleep Mode the PSD4XX consumes less power than the Power Down Mode. In this mode, the ZPLD still monitors the inputs and responds to them. As soon as the ALE starts pulsing, the PSD4XX exits the Sleep Mode. The PSD access time from Sleep Mode is specified by t LVDV1. The ZPLD response time to an input transition is specified by t LVDV2. 67 PSD4XX Family The PSD4XX Architecture Figure 36. Power Management Unit (cont.)

These options, except the SRAM Standby Mode, can be enabled/disabled by setting up the corresponding bit in the PMMR. EPROM The EPROM power consumption in the PSD is controlled by bit 3 in the PMMR0 - EPROM CMiser. Upon reset the CMiser bit is OFF. This will cause the EPROM to be ON at all times as long as CSI is enabled (low). The reason this mode is provided is to reduce the access time of the EPROM by 10 ns relative to the low power condition when CMiser is ON. If CSI is disabled (high) the EPROM will be deselected and will enter standby mode (OFF) overriding the state of the CMiser. If CMiser is set (ON) then the EPROM will enter the standby mode when not selected. This condition can take place when CSI is high or when CSI is low and the EPROM is not accessed. For example, if the MCU is accessing the SRAM, the EPROM will be deselected and will be in low power mode. An additional advantage of the CMiser is achieved when the PSD is configured in the by 8 mode (8 bit data bus). In this case an additional power savings is achieved in the EPROM (and also in the SRAM) by turning off 1/2 of the array even when the EPROM is accessed (the array is divided internally into odd and even arrays). The power consumption for the different EPROM modes is given in the DC Characteristics table under ICC (DC) EPROM Adder. SRAM Standby Mode The SRAM has a dedicated supply voltage VSTBY that can be used to connect a battery. When VCC becomes lower than VSTBY -0.6 then the PSD will automatically connect the VSTBY as a power source to the SRAM. The SRAM Standby Current (ISTBY) is typically 0.5 A. SRAM data retention voltage VDF is 2 V minimum. Zero Power ZPLD ZPLD power/speed is controlled by the ZPLD_Turbo bit (bit 4) in the PMMR0. After reset the ZPLD is in Turbo mode and runs at full power and speed. By setting the bit to "1", the Turbo mode is disabled and the ZPLD is consuming Zero Power current if the inputs are not switching for an extended time of 70 ns. The propagation delay time will be increased by 10ns after the Turbo bit is set to "1" (turned off) if the inputs change at a frequency of less than 15 MHz. 70 PSD4XX Family The PSD4XX Architecture (cont.) Input Clock The PSD4XX provides the option to turn off the clock inputs to save AC power consumption. The clock input (CLKIN) is used as a source for driving the following modules: ZPLD Array Clock Input ZPLD MacroCell Clock Flip Flop APD Counter Clock During power down or if any of the modules are not being used the clock to these modules should be disabled. To reduce AC power consumption, it is especially important to disable the clock input to the ZPLD array if it is not used as part of a logic equation. The ZPLD Array Clock can be disabled by setting PMMR0 bit 5 (ZPLD ACLK). The ZPLD MacroCell Clock Input can be disabled by setting PMMR0 bit 6 (ZPLD RCLK). The Timer Clock can be disabled by setting PMMR0 bit 7 (TMR CLK). The APD Counter Clock will be disabled automatically if Power Down or Sleep Mode is entered through the APD unit. The input buffer of the CLKIN input will be disabled if bits 5 - 7 PMMR0 are set and the APD has overflowed.

In Sleep Mode any input to the ZPLD will have a propagation delay of t LVDV2. 3. PLD recovery time to normal operation after exiting Sleep Mode. An input to the ZPLD during the transition will have a propagation delay time of t LVDV3. Table 20.

By including the four outputs as inputs to the DPLD, the addressing capability of the microcontroller is increased by a factor of 16. Figure 37 shows the Page Register block diagram. Inputs to the four flip flops are connected to data bus D0-D3. The output of the Register can be read by the microcontroller. The Register can operate as an independent register to the microcontroller if page mode is not implemented. Figure 35.

RS0 PGR0 PGR1 PGR2 GPLD PGR3 ZPLD The PSD4XX has a programmable security bit which offers protection from unauthorized duplication. When the security bit is set, the contents of the EPROM, the PSD4XX non-volatile configuration bits and ZPLD data cannot be read by EPROM programmers. The security bit is set through the PSDsoft Software and is embedded in the compiled output file. The security bit is UV erasable and a secured part can be erased and then re-programmed. 72 PSD4XX Family 12.0 System Configuration The CSIOP signal, which is generated by the DPLD, selects the internal I/O devices or registers. The CSIOP signal takes up 256 bytes of address space and is defined by the user in the PSDSoft Software. The following is an address offset map for the various devices relative to the CSIOP base address. Some Motorola 16-bit microcontrollers have a different data bus/data byte orientation. This requires a different address offset for the internal PSD4XX I/O devices or registers. Tables 21a and 22a in this section are for this group of microcontrollers which include the M68HC16, M68302 and M683XX. Table 21.

The Timing Diagram in the AC/DC characterization section shows the reset signal timing requirement. The active low range has a minimum T1 duration. After the rising edge of RESET, the PSD4XX remains in reset during T2 range. (See Figure 48). The PSD4XX must be reset at power up before it can be used. 12.2 ZPLD and Memory During Reset While the Reset Input is active, the ZPLD generates outputs as defined in the PSDabel equations. The EPROM and SRAM blocks respond to the microcontroller bus cycle during reset, but the data is not guaranteed. 12.3 Register Values During and After Reset Table 24 summarizes the status of the volatile register values during and after reset. The default values of the volatile registers are "0" after reset. 12.4 ZPLD Macrocell Initialization The D flip flops in the macrocells in the GPLD can be cleared by: A product term (.RE) defined by the user in PSDabel, or The MACRO-RST (Reset) input, enabled and defined in PSDabel.

AC Testing Load Circuit 2.01 V 195 DEVICE UNDER TEST 17.0 Erasure and Programming CL = 30 pF (INCLUDING SCOPE AND JIG CAPACITANCE) To clear all locations of their programmed contents, expose the window packaged device to an ultra-violet light source. A dosage of 30 W second/cm 2 is required (40 W second/cm 2 for ZPSD4XXV versions). This dosage can be obtained with exposure to a wavelength of 2537 A and intensity of 12000 W/cm 2 for 40 to 45 minutes (55 to 60 minutes for ZPSD4XXV versions). The device should be about 1 inch from the source, and all filters should be removed from the UV light source prior to erasure. The PSD4XX and similar devices will erase with light sources having wavelengths shorter than 4000 A. Although the erasure times will be much longer than with UV sources at 2537 A, exposure to fluorescent light and sunlight eventually erases the device. For maximum system reliability, these sources should be avoided. If used in such an environment, the package windows should be covered by an opaque substance. Upon delivery from ST, or after each erasure, the PSD4XX device has all bits in the PAD and EPROM in the "1" or high state. The configuration bits are in the "0" or low state. The code, configuration, and PAD MAP data are loaded through the procedure of programming Information for programming the device is available directly from ST.
