These devices are designed to replace multiple traditional MCU-based system components with one low cost single-chip programmable component. A PSoC device includes configurable blocks of analog and digital logic, and programmable interconnect. This architecture enables the user to create customized peripheral configurations, to match the requirements of each individual application. Additionally, a fast CPU, Flash program memory, SRAM data memory, and configurable IO are included in a range of convenient pinouts. The PSoC architecture, shown in Figure 1, consists of four main areas: the Core, the System Resources, the Digital System, and the Analog System. Configurable global bus resources allow combining all the device resources into a complete custom system. Each CY8C21x34 PSoC device includes four digital blocks and four analog blocks. Depending on the PSoC package, up to 28 general purpose IO (GPIO) are also included. The GPIO provide access to the global digital and analog interconnects. The PSoC Core The PSoC Core is a powerful engine that supports a rich instruction set. It encompasses SRAM for data storage, an interrupt controller, sleep and watchdog timers, and IMO (internal main oscillator) and ILO (internal low speed oscillator). The CPU core, called the M8C, is a powerful processor with speeds up to 24 MHz. The M8C is a four MIPS 8-bit Harvard architecture microprocessor. The Digital System The Digital System consists of 4 digital PSoC blocks. Each block is an 8-bit resource that is used alone or combined with other blocks to form 8, 16, 24, and 32-bit peripherals, which are called user module references. Digital peripheral configurations include the following. PWMs (8 to 32 bit) PWMs with Dead band (8 to 32 bit) Counters (8 to 32 bit) Timers (8 to 32 bit) UART 8 bit with selectable parity SPI master and slave I2C slave and multi-master Cyclical Redundancy Checker/Generator (8 to 32 bit) IrDA Pseudo Random Sequence Generators (8 to 32 bit) The digital blocks are connected to any GPIO through a series of global buses that can route any signal to any pin. The buses also allow for signal multiplexing and for performing logic operations. This configurability frees your designs from the constraints of a fixed peripheral controller. System Resources provide the following additional capabilities: Digital blocks are provided in rows of four, where the number of blocks varies by PSoC device family. This allows the optimum choice of system resources for your application. Family resources are shown in Table 1 on page 4. Digital clocks to increase the flexibility of the PSoC mixed-signal arrays.

The digital blocks are connected to the GPIO through a series of global buses that can route any signal to any pin, freeing designs from the constraints of a fixed peripheral controller. The Analog System consists of four analog PSoC blocks, supporting comparators and analog-to-digital conversion up to 8 bits in precision.

Analog peripherals are very flexible and may be customized to support specific application requirements. Some of the common PSoC analog functions for this device (most available as user modules) are: The Analog Mux Bus can connect to every GPIO pin. Pins may be connected to the bus individually or in any combination. The bus also connects to the analog system for analysis with comparators and analog-to-digital converters. An additional 8:1 analog input multiplexer provides a second path to bring Port 0 pins to the analog array. Analog-to-digital converters (single or dual, with 8-bit resolution) Pin-to-pin comparator Single-ended comparators (up to 2) with absolute (1.3V) reference or 8-bit DAC reference Track pad, finger sensing. 1.3V reference (as a System Resource) Chip-wide mux that allows analog input from any IO pin. Crosspoint connection between any IO pin combinations. In most PSoC devices, analog blocks are provided in columns of three, which includes one CT (Continuous Time) and two SC (Switched Capacitor) blocks. The CY8C21x34 devices provide limited functionality Type "E" analog blocks. Each column contains one CT Type E block and one SC Type E block. Refer to the PSoC Mixed-Signal Array Technical Reference Manual for detailed information on the CY8C21x34's Type E analog blocks. Figure 2. Analog System Block Diagram Array Input Configuration ACI0[1:0] Switch control logic enables selected pins to precharge continuously under hardware control. This enables capacitive measurement for applications such as touch sensing. Other multiplexer applications include: When designing capacitive sensing applications, refer to the signal-to-noise system level requirement found in Application Note AN2403 on the Cypress web site at http://www.cypress.com. Additional System Resources System Resources, some of which are listed in the previous sections, provide additional capability useful to complete systems. Additional resources include a switch mode pump, low voltage detection, and power on reset. Brief statements describing the merits of each system resource follow. Digital clock dividers provide three customizable clock frequencies for use in applications. The clocks may be routed to both the digital and analog systems. Additional clocks can be generated using digital PSoC blocks as clock dividers. The I2C module provides 100 and 400 kHz communication over two wires. Slave, master, and multi-master modes are all supported. Low Voltage Detection (LVD) interrupts can signal the application of falling voltage levels, while the advanced POR (Power On Reset) circuit eliminates the need for a system supervisor. An internal 1.3 voltage reference provides an absolute reference for the analog system, including ADCs and DACs. An integrated switch mode pump (SMP) generates normal operating voltages from a single 1.2V battery cell, providing a low cost boost converter. Versatile analog multiplexer system.

Getting Started Development Tools The quickest path to understanding the PSoC silicon is by reading this data sheet and using the PSoC Designer Integrated Development Environment (IDE). This data sheet is an overview of the PSoC integrated circuit and presents specific pin, register, and electrical specifications. For in-depth information with detailed programming information, refer the PSoC Mixed-Signal Array Technical Reference Manual available at http://www.cypress.com/psoc. PSoC Designer is a Microsoft(R) Windows-based, integrated development environment for the Programmable System-on-Chip (PSoC) devices. The PSoC Designer IDE and application runs on Windows NT 4.0, Windows 2000, Windows Millennium (Me), or Windows XP. (See Figure 3 on page 5) For up-to-date Ordering, Packaging, and Electrical Specification information, refer the latest PSoC device data sheets at http://www.cypress.com. Development Kits Development Kits are available from the following distributors: Digi-Key, Avnet, Arrow, and Future. The Cypress Online Store Document Number: 38-12025 Rev. *M PSoC Designer helps the customer to select an operating configuration for the PSoC, write application code that uses the PSoC, and debug the application. This system provides design database management by project, an integrated debugger with In-Circuit Emulator, in-system programming support, and the CYASM macro assembler for the CPUs. PSoC Designer also supports a high-level C language compiler developed specifically for the devices in the family.

PSoC Designer Subsystems Design Browser The Design Browser enables users to select and import preconfigured designs into the user's project. Users can easily browse a catalog of preconfigured designs to facilitate time-to-design. Examples provided in the tools include a 300-baud modem, LIN Bus master and slave, fan controller, and magnetic card reader. Application Editor In the Application Editor you can edit your C language and Assembly language source code. You can also assemble, compile, link, and build. Assembler. The macro assembler allows the seamless merging of the assembly code with C code. The link libraries automatically use absolute addressing or are compiled in relative mode, and linked with other software modules to get absolute addressing. C Language Compiler. A C language compiler that supports the PSoC family of devices is available. Even if you have never worked in the C language before, the product quickly helps you create complete C programs for the PSoC family devices. The embedded, optimizing C compiler provides all the features of C tailored to the PSoC architecture. It comes complete with embedded libraries providing port and bus operations, standard keypad and display support, and extended math functionality. Debugger PSoC Designer Software Subsystems The PSoC Designer Debugger subsystem provides hardware in-circuit emulation, allowing the designer to test the program in a physical system while providing an internal view of the PSoC device. Debugger commands allow the designer to read the program and read and write data memory, read and write IO registers, read and write CPU registers, set and clear breakpoints, and provide program run, halt, and step control. The debugger also allows the designer to create a trace buffer of registers and memory locations of interest. Device Editor The device editor subsystem enables the user to select different onboard analog and digital components called user modules using the PSoC blocks. Examples of user modules are ADCs, DACs, Amplifiers, and Filters. The device editor also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic reconfiguration allows changing configurations at run time. PSoC Designer sets up power on initialization tables for selected PSoC block configurations and creates source code for an application framework. The framework contains software to operate the selected components and, if the project uses more than one operating configuration, contains routines to switch between different sets of PSoC block configurations at run time. PSoC Designer can print out a configuration sheet for a given project configuration for use during application programming in conjunction with the Device Data Sheet. After the framework is generated, the user can add application-specific code to flesh out the framework. It is also possible to change the selected components and regenerate the framework. Document Number: 38-12025 Rev. *M Online Help System The online help system displays online, context-sensitive help for the user. Designed for procedural and quick reference, each functional subsystem has its own context-sensitive help. This system also provides tutorials and links to FAQs and an Online Support Forum to aid the designer in getting started. Hardware Tools In-Circuit Emulator A low cost, high functionality ICE (In-Circuit Emulator) is available for development support. This hardware has the capability to program single devices. The emulator consists of a base unit that connects to the PC by way of a USB port. The base unit is universal and operates with all PSoC devices. Emulation pods for each device family are available separately. The emulation pod takes the place of the PSoC device in the target board and performs full speed (24 MHz) operation. Page 5 of 43 [+] Feedback CY8C21634, CY8C21534 CY8C21434, CY8C21334, CY8C21234 Designing with User Modules The development process for the PSoC device differs from that of a traditional fixed function microprocessor. The configurable analog and digital hardware blocks give the PSoC architecture a unique flexibility that pays dividends in managing specification change during development and by lowering inventory costs. These configurable resources, called PSoC Blocks, have the ability to implement a wide variety of user-selectable functions. Each block has several registers that determine its function and connectivity to other blocks, multiplexers, buses and to the IO pins. Iterative development cycles permit you to adapt the hardware and software. This substantially lowers the risk of having to select a different part to meet the final design requirements. To speed the development process, the PSoC Designer Integrated Development Environment (IDE) provides a library of pre-built, pre-tested hardware peripheral functions, called "User Modules." User modules make selecting and implementing peripheral devices simple, and come in analog, digital, and mixed signal varieties. The standard User Module library contains over 50 common peripherals such as ADCs, DACs Timers, Counters, UARTs, and other uncommon peripherals, such as DTMF Generators and Bi-Quad analog filter sections. Each user module establishes the basic register settings that implement the selected function. It also provides parameters that allow you to tailor its precise configuration to your particular application. For example, a Pulse Width Modulator User Module configures one or more digital PSoC blocks, one for each 8 bits of resolution. The user module parameters permit you to establish the pulse width and duty cycle. User modules also provide tested software to cut your development time. The user module application programming interface (API) provides high-level functions to control and respond to hardware events at run time. The API also provides optional interrupt service routines that you can adapt as needed. The API functions are documented in user module data sheets that are viewed directly in the PSoC Designer IDE. These data sheets explain the internal operation of the user module and provide performance specifications. Each data sheet describes the use of each user module parameter and documents the setting of each register controlled by the user module. The development process starts when you open a new project and bring up the Device Editor, a graphical user interface (GUI) for configuring the hardware. You can pick the user modules you need for your project and map them onto the PSoC blocks with point-and-click simplicity. Next, you build signal chains by interconnecting user modules to each other and the IO pins. At this stage, you must also configure the clock source connections and enter parameter values directly or by selecting values from drop-down menus. When you are ready to test the hardware configuration or move on to developing code for the project, perform the "Generate Application" step. This causes PSoC Designer to generate source code that automatically configures the device to your specification and provides the high-level user module API functions.

User Module and Source Code Development Flows Device Editor User Module Selection Placement and Parameter -ization Source Code Generator Generate Application Application Editor Project Manager Source Code Editor Build Manager Build All Debugger Interface to ICE Storage Inspector Event & Breakpoint Manager The next step is to write your main program, and any sub-routines using PSoC Designer's Application Editor subsystem. The Application Editor includes a Project Manager that allows you to open the project source code files (including all generated code files) from a hierarchal view. The source code editor provides syntax coloring and advanced edit features for both C and assembly language. File search capabilities include simple string searches and recursive "grep-style" patterns. A single mouse click invokes the Build Manager. It employs a professional-strength "makefile" system to automatically analyze all file dependencies and run the compiler and assembler as necessary. Project-level options control optimization strategies used by the compiler and linker. Syntax errors are displayed in a console window. Double clicking the error message takes you directly to the offending line of source code. When all is correct, the linker builds a HEX file image suitable for programming. The last step in the development process takes place inside the PSoC Designer's Debugger subsystem. The Debugger downloads the HEX image to the In-Circuit Emulator (ICE) where it runs at full speed. Debugger capabilities rival those of systems costing many times more. In addition to traditional single-step, run-to-breakpoint and watch-variable features, the Debugger provides a large trace buffer and enables you to define complex breakpoint events that include monitoring address and data bus values, memory locations, and external signals.
