TWR-56F8257 Board 2.1 Tower MCU Module The TWR-56F8257 board is an MCU module designed for use with a Freescale Tower System and complies with the electrical and mechanical specification as described in Freescale Tower Electromechanical Specification. Connection to the Tower System is enabled through two expansion card edge connectors that interface to the elevator boards in a Tower System: the primary and secondary elevator connectors. The primary elevator connector, comprised of sides A and B, is utilized by the TWR-56F8257, while the secondary elevator connector only makes connections to ground (GND). On sheet 7 of the schematic, the J500A and J500B symbols have names assigned to the card edge fingers that correspond with the normal Tower pin assignments. The pin out details for the TWR-56F8257 can be found in the TWR-56F8257 Module Pin out document. 2.2 System Power The TWR-56F8257 board contains three power rails: P5V_USB, P3_3V and P3_3V/5V. They are sourced and used as follows: Freescale Semiconductor, Inc. TWR-56F8257 User Manual 5 2.2.1 P5V_USB The P5V_USB power rail is derived from the Mini-B USB connector at J18 and the inductor at L2. It is used to power the on-board OSBDM/ serial bridge circuit. This consists of the OSBDM MCU at U6, several pull-up resistors at R13, R14, R15, R527 and R528, the USB power switch at U501, and the STATUS and TPWR LEDs at D12 and D13. If there is no USB cable connected to J18 there is no power on this rail and these circuits are all powered down. 2.2.2 P3_3V The P3_3V power rail is derived from a) the P3_3V_MOTOR power net from the motor control board connector at J501, b) the P3_3V_ELEV power net from the Tower connector at J500A, or c) the on-board 3.3V regulator at U1. The selection of the source is made with a shunt at J6 and J7. Table 6 shows the operation of the different shunt positions. The selection of power into the regulator is made with a shunt at J10 and J11 which selects from a) the P5V_TRG_USB power net out of the USB switch at U501, b) the P5V_ELEV power net from the elevator connection at J500A pins A1 and B1, or c) the PWR_IN power net from the 2 mm barrel jack at J3 through resettable fuse F1. Table 6 shows the operation of the different shunt positions. The barrel jack input is protected from reverse voltage inputs by diode D11. The input to the barrel jack may be from a 5V to 9V source and must be center positive. The P3_3V power rail provides power to the majority of the circuits on the board including the MC56F8257 (including the analog power pins through L500 and L501), inverters at U500 and U502, a multiplexor at U505, the on-board LEDs at D1-D9, the thermistor divider circuits at RT1-RT4, and the pull-up resistors at R2, R3, R11, R565, R570 and R562. 2.2.3 P3_3V/5V The P3_3V/5V power rail is derived from the diode OR (using D500 and D501) of a) the P5V_ELEV power net from the elevator connection (J500A pins A1 and B1), b) the P5V output of the USB power switch at U501, or c) the P3_3V power rail from J7. When there is a USB cable connected or when the Tower elevator boards are connected this power rail will be a Schottky diode drop (about 0.3V) below the 5V power nets. When there is no 5V source this power rail will be a Schottky diode drop below the P3.3V power rail. This allows the inputs of the ICs powered by this rail to stay in a high impedance state instead of loading down the inputs through the input protection diodes as would happen if there were no power supplied to the buffers. 2.2.4 Default Power Configuration The TWR-56F8257 board default power configuration uses the OSBDM USB port for all power. As soon as the OSBDM firmware has started it negotiates with the host PC USB port for full USB power. Once approved it enables the 5V USB power switch (U501) which provides 5V to the P3_3V/5V power rail and to the 3.3V regulator (U1) through headers J10 and J11. Likewise, the on-board voltage regulator provides 3.3V to the P3_3V power rail through headers J6 and J7. The 3.3V regulator is able to provide up to 700 mA subject to the power dissipation and temperature limits of the device. 2.3 MC56F8257 DSC The primary circuits on the board are related to the MC56F8257 DSC. This part is supplied in a surface-mounted, 64-pin LQFP package at U2. Although the board was laid out to allow a ZIF socket at U3 in parallel to the chip at U2, the TWR-56F8257 is only available with the surface mounted chip. 2.3.1 Clock Sources for the MC56F8257 DSC Three options are provided for clocking the MC56F8257 device: 1. Oscillator internal to the MC56F8257 chip: approximately 8 MHz 2. 8 MHz crystal 3. External clock input from primary Tower connector or the AUX connector The internal oscillator is used to clock the MC56F8257 immediately following reset. This is the default operation. In this mode the zero ohm resistors at R4 and R10 allow the GPIOC0 and GPIOC1 pins of the MC56F8257 (pins 3 and 4) to be used as inputs or outputs. 6 TWR-56F8257 User Manual Freescale Semiconductor, Inc. To use an external crystal with the MC56F8257, zero ohm resistors R4 and R10 must be removed and placed in the R5 and R7 positions. The desired crystal, load capacitors and parallel resistor (if needed) must be soldered to the board at Y1, C5, C6 and R6. (These components are not provided with the TWR-56F8257 kit.) Following reset, reconfigure the GPIOC0 and GPIOC1 pins to the XTAL and EXTAL functions to allow the use of an external crystal. To use an external clock for the MC56F8257, make sure the zero ohm resistors are installed at R4 and R10 and removed from R5 and R7. Provide a clock signal on either the primary Tower connector J500A, pin B24 (the pin designated as CLOCKIN0) or on the AUX connector J502, pin 8. Following reset, configure the GPIOC0 pin to the CLKIN input function. In this mode the zero ohm resistor at R10 allows the GPIOC1 pin of the MC56F8257 (pin 10) to be used as an input or output. 2.3.2 Serial I/O Source Select Headers The TWR-56F8257 board allows the UART functions of the MC56F8257 DSC to be connected to a serial interface at the primary Tower connector J500A or through a USB bridge to the host PC using the OSBDM MCU (U6). The selection of the RXD connections is done with the header at J8 as shown in Table 1. The selection of the TXD connections is done with the header at J9 as shown in Table 2. Table 1.

Shunt pins 3 and 4 together to connect the DSC TXD1 pin to the USB serial bridge function. Shunt pins 4 and 5 together to connect the DSC TXD1 pin to the primary Tower Connector TXD1 pin. (This is a default position.) As noted in Tables 1 and 2, the 56F8257 DSC serial signals may be connected to either the Tower serial signals or to the USB bridge chip however, only one channel may be connected to the USB bridge chip. If the associated 56F8257 DSC serial pins are not being used for the serial functions the shunts should be removed for those pins. For more information on the USB serial bridge function see section 2.4.2 USB serial bridge interface. Freescale Semiconductor, Inc. TWR-56F8257 User Manual 7 2.3.3 LEDs Controlled by the MC56F8257 DSC There are nine LEDs with buffers connected to the MC56F8257 DSC. Inverting buffers (U500A-F and U502D-F) isolate the LEDs from the DSC pins by providing high impedance inputs. The LEDs are powered by the P3_3V rail and draw about 5 mA each. Table 3 shows the DSC pin names associated with each LED. Table 3.

The motor control connector (J501) is on the bottom of the board to provide a convenient connection to the motor control board. For convenience, the pins of the motor control connector may be probed from the top of the board. Many of the MC56F8257 DSC pins are connected to the motor control connector. Those pins associated with analog inputs have 100 ohm resistors in series to provide some ESD protection for the analog inputs of the DSC. Those pins providing analog signals from the motor control board have 2200 pf caps with the resistors to provide a low pass filter. The connector pin out is shown in Table 4. Table 4.

This connector provides access to the MC56F8257 DSC signals that are not covered by the motor control connector. Those pins associated with analog inputs have 100 ohm resistors in series to provide some ESD protection for the analog inputs of the DSC. The connector pin out is shown in Table 5. Table 5.

The primary elevator connector, comprised of sides A and B, is utilized by the TWR-56F8257 board, while the secondary elevator connector only makes connections to ground (GND). Table 7 in Appendix A: Tower Elevator Connector Pin Functions, lists the pin functions for the primary elevator connector. 2.3.7 Thermistors as Analog Inputs The TWR-56F8257 board provides four thermistors (RT1-4) near the corners of the board that can be used as single ended or differential analog inputs to the MC56F8257 DSC as can be seen on sheet 6 of the schematic. In addition to each thermistor there is a resistor between the thermistor and P3_3V and another resistor between the thermistor and ground. The thermistors are all 10K ohm parts but the associated divider chain uses different resistors. This may increase or decrease the voltage across the thermistor and provides the ability to try the different gain settings on the analog channels. All four thermistor circuits are designed to provide useable differential inputs over the temperature range of -20C to +90C. RT2 and RT4 both give a differential voltage of ~1.65V at 25C. RT1 gives a differential voltage of 0.10V and RT3 gives a differential voltage of 0.28V at 25C. In addition to the thermistor voltage divider chain, each thermistor has a 0.1 uF capacitor in parallel. Each thermistor circuit also has a header that allows the thermistor to be disconnected from the analog inputs to the DSC. If a user wishes to apply an external analog value, these headers may be removed and the external analog signal attached to the DSC side of the headers. Finally, each analog input to the DSC has a 100 ohm series resistor and a 2200 pF capacitor as a low pass filter. This helps protect the DSC from electrostatic discharges and lowers the impedance of the analog signal so that it can be sampled with less noise. Freescale Semiconductor, Inc. TWR-56F8257 User Manual 9 2.3.8 CAN Transceiver The TWR-56F8257 board has a CAN transceiver circuit that may be connected to the CAN pins of the DSC. The CAN transceiver (U503) can be connected to the GPIOC11/CANTX/SCL1/TXD and GPIOC12/CANRX/SDA1/RXD1 pins of the DSC through the header at J16. Installing a shunt from pin 1 to pin 2 connects the TXD nets and installing a shunt from pin 3 to pin 4 connects the RXD nets. Note that the GPIOC11/ CANTX/SCL1/TXD and GPIOC12/CANRX/SDA1/RXD1 nets also go to the primary elevator edge connector (J500A) pins B41 and B42 and to the auxiliary connector (J502) pins 15 and 17. When using these nets for CAN communications care must be taken that these nets are not driven from these other connectors. The transceiver is capable of running from 3.3V and is powered by the P3_3V/5V power rail. The transceiver output is connected to header J13 with CANH connected to pin 4 and CANL connected to pin 3. A 120 ohm parallel termination resistor may be connected between these nets by installing a shunt on header J15. 2.3.9 IRQ or Input Pushbuttons The TWR-56F8257 board has two push buttons (SW1 and SW2) that can be used to provide inputs or interrupts to the DSC. Each has a 10K ohm pull up resistor to P3_3V and a 0.1 uF capacitor to ground to minimize bounce on the output. Push button SW1 is connected to header J4 where the switch output can be connected to either DSC pin GPIOC2/TXD0/TB0/XB_IN2/CLKO (default) or GPIOF6/TB2/PWM3X depending on the position of the shunt on the header (pin 1 to pin 2 is the default). Similarly, push button SW2 is connected to header J5 where the switch output can be connected to either DSC pin GPIOF8/RXD0/TB1 (default) or GPIOF7/TB3 depending on the position of the shunt on the header (pin 1 to pin 2 is the default). If the push button switches are not being used as an interrupt or other it is best to remove the shunt to the DSC so that the 0.1 uF capacitor is not loading down the DSC pins. 2.3.10 RESET The GPIOD4/RESET_B pin of the DSC is connected to the motor control connector and the Tower connector but also to a push button (SW3) and through buffers to the OSBDM chip. It is pulled to P3_3V by a 10K ohm resistor. It may be pulled low by the push button or by Q1 in response to a high output from the OSBDM chip (pin 1) on the TRESET_OUT net. The state of the GPIOD4/RESET_B signal is provided to the OSBDM chip through a voltage translator (U504B). This buffer is powered by the P3_3V/5V power rail so that its input will remain high impedance when there is no USB cable connected. The buffered RESET signal is provided to pin 33 of the OSBDM chip and is used by the OSBDM program in that chip. 2.3.11 JTAG Header and OSBDM Disconnect Header The TWR-56F8257 board includes an OSBDM circuit as a debug interface to the MC56F8257 DSC for normal purposes. If the user desires to use a different debugger header J14 provides a connection point for an external JTAG based debugger. If an external debugger is connected to the JTAG header the shunts at J21 (pins 1 to 2, 3 to 4, 5 to 6 and 7 to 8) which connect the OSBDM circuit to the JTAG signals should be removed. The TWR-56F8257 board provides a 2.2K ohm pull up resistor to 3.3V on the TMS line. If an external JTAG debugger also has a pull up on this line the external debugger may not be able to pull the TMS line low. If this occurs, remove one of the pull up resistors on the TMS line. 10 TWR-56F8257 User Manual Freescale Semiconductor, Inc. 2.4 OSBDM 2.4.1 Debug Interface An on-board MC9S08JM60 based OSBDM circuit provides a debug interface to the MC56F8257. A standard USB A male to Mini-B male cable (supplied) can be used for debugging via the USB connector, J18. 2.4.2 USB Serial Bridge Interface The on-board MC9S08JM60 can also be used as a USB to serial bridge interface for the UART signals from the MC56F8257 DSC. This bridge circuit is described in detail in section 2.3.2 Serial I/O Source Select Headers. The RXD_SEL signal goes to the MC56F8257 DSC. The USB bridge chip is powered by 5V so its output is a 5V output. The multiplexor (U505) is able to accept the 5V signal from the USB bridge chip (T_TXD1) and converts it to the 3.3V signal (RXD_SEL) for the DSC. The multiplexor output is enabled by an inverted RTS signal (TXD_RXD_EN_B) from the USB bridge chip. If there is no USB connection to the Tower board the RTS signal is not driven and the 3.3V powered inverter (U502C) input is biased low disabling the output of the multiplexor. Similarly, TXD_SEL is a 3.3V signal from the MC56F8257 DSC. The USB bridge chip is expecting a 5V input on T_RXD1. The buffer between these two signals (U504C) is powered by P3_3V/5V. It will accept the 3.3V input from the DSC and convert it to the 5V signal needed by the USB bridge chip. The buffer output is enabled by the same inverted RTS signal (TXD_RXD_EN_B) discussed above. If there is no USB connection to the TWR board the RTS signal is not driven and the 5V powered buffer disabled so nothing is driving the powered down USB bridge chip. The USB serial bridge interface is enabled by removing the shunt on J20 before applying power to the board. The serial interface signals from the MC56F8257 DSC are routed to the MC9S08JM60 serial interface. In the USB serial bridge mode the MC9S08JM60 will convert the serial interface data into USB packets and send them to the host PC. 2.4.3 Clocking the OSBDM MCU (MC9S08JM60) The MC9S08JM60 MCU uses an on-board 4 MHz external crystal circuit (Y2, R16, C7, and C9) for its clock. There are no user options for clocking the MC9S08JM60. 2.4.4 OSBDM/UART Function Select Header Header J20 selects whether the on-board MC9S08JM60 MCU operates as an OSBDM debug interface or as a USB serial bridge interface. Leaving the shunt on the header enables the OSBDM debug interface. Removing the shunt on header J20 enables the USB serial bridge interface. 2.4.5 Bootloader Enable In addition to the OSBDM debug interface and the USB serial bridge interface the MC9S08JM60 device used in the OSBDM circuit is pre-programmed with a USB bootloader. The USB bootloader will run following a power-on reset if a shunt is installed on header J17. This allows in-circuit reprogramming of the JM60 flash memory via USB. This enables the OSBDM firmware to be upgraded by the user when upgrades become available. In normal OSBDM or USB serial bridge operation this shunt must be left off. For details on the USB bootloader, refer to application note AN3561at freescale.com. The USB bootloader communicates with a GUI application running on a host PC. The GUI application can be found at freescale.com: search keyword "JM60 GUI." Refer to section 2.5 and 3.3 of AN3561 for details on installing and running the application. Note: The JM60 GUI installer should be run before connecting the OSBDM in Bootloader Mode to a host USB port. Otherwise, the JM60 USB device will not be recognized and the proper drivers will not be loaded. Freescale Semiconductor, Inc. TWR-56F8257 User Manual 11 2.4.6 BDM Header The BDM header at J22 is used for initial programming of the MC9S08JM60 MCU or if re-programming with the bootloader fails. An external 9S08 BDM debugger would be connected to J22 and used to program the MCU. This is not expected to be a normal user interface. 2.4.7 OSBDM Status LEDs The MC9S08JM60 OSBDM MCU controls two status LEDs at D12 and D13. Refer to the OSBDM instructions for the meaning of the LEDs. 2.4.8 OSBDM Voltage Translation Since the OSBDM MCU runs from 5V and the 56F8257 DSC runs from 3.3V there must be voltage translation between the two circuits. This is done through U505, U504A and U502B. U505 has 5V tolerant inputs and provides 3.3V signals (TCK, TDI, and TMS) to the DSC's JTAG pins through the shunts on header J21. U504A is powered by the P3_3V/5V rail and translates the 3.3V TDO signal from the DSC to a 5V signal for the OSBDM MCU. The outputs of both of these translators are high impedance if the signal OUT_EN_B goes high. This happens if the OSBDM circuit looses power (no power to the USB connector). In that case, the OUT_EN signal from the OSBDM MCU (pin 15) is biased low by R12. The inverter at U502B then drives OUT_EN_B high in response. Additional information is included in section 2.4.2. 12 TWR-56F8257 User Manual Freescale Semiconductor, Inc.
