2.1 Tower system MCU module
The TWR-56F8200 board is an MCU module designed for standalone use (or with a Freescale Tower
system) and complies with the electrical and mechanical specification as described in Freescale Tower
Electromechanical Specification [1]. Connection to the Tower system is through two expansion cardedge 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-56F8200, while the Secondary Elevator connector only makes connections to ground (GND). On
sheet 8 of the TWR-56F8200-SCH (See Appendix B—TWR-56F8200 board schematic), the J500A and
J500B symbols have names assigned to the card edge fingers that correspond with the normal Tower
system pin assignments.
Note: On the top and bottom of one edge of the TWR-56F8200 board, there is a WHITE BELT; the
card-edge connectors next to the WHITE BELT on the TWR-56F8200 board should be connected to the
Primary Elevator board which uses the WHITE PCI connector. The card-edge connectors without the
WHITE BELT on the TWR-56F8200 board should be connected to the secondary Elevator board (or left
unconnected) using the Black PCI connector. This instruction overrides any silkscreen information that
may be present, such as the words “Primary” or “Secondary” on the TWR-56F8200, since early
revisions had this reversed.
2.2 System power
The TWR-56F8200 board has three power rails: P5V_USB, P3_3V, and P3_3V/5V. The sources and
usage of these power rails is described as follows.
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/OSJTAG/Serial Bridge circuit. This consists of the
OSBDM/OSJTAG MCU at U6, several pullup 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 all these circuits are powered down.
2.2.2 P3_3V
The P3_3V power rail is derived from either of the following sources.

the P3_3V_MOTOR power net from the motor control board connector at J501,

the P3_3V_ELEV power net from the Tower connector at J500, or

the onboard 3.3 V regulator at U1
The selection of any of these power sources is made with a shunt from J7-2 (jumper J7 pin 2) to another
pin of J7 or to J6. A shunt from J11-2 (Jumper J11-pin2) to another pin of J11 or to J10, is used to select
power to the regulator from the following sources:
TWR-56F8200 Tower Board, Rev. 1, 10/2013
4
Freescale Semiconductor Inc.

the P5V_TRG_USB power net out of the USB switch at U501,

the P5V_ELEV power net from the elevator connection at J500 pins A1 and B1, or

the PWR_IN power net from the 2mm 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 5-9 V source and needs
to be center-positive.
The P3_3V power rail provides power to the majority of the circuits on the board including the
MC56F82748 (including the analog power pins through L500 and L501), inverters at U500 and U502, a
buffer at U505, the onboard LEDs at D1-D9, the thermistor divider circuits at RT1-RT4, and the pullup
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:

the P5V_ELEV power net from the elevator connection (J500 pins A1 and B1),

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 5 V power nets. When there is no 5 V 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-56F8200 board default power configuration uses the OSBDM/OSJTAG USB port for all
power. As soon as the OSBDM/OSJTAG 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 5 V to
the P3_3V/5 V power rail and to the 3.3 V regulator (U1) through headers J10 and J11. Likewise, the
onboard voltage regulator provides 3.3 V to the P3_3V power rail through headers J6 and J7. The 3.3 V
regulator is able to provide up to 700 mA current, subject to the power dissipation and temperature
limits of the device.
2.3 MC56F82748 DSC
The primary circuits on the board are related to the MC56F82748 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-56F8200 is only available for purchase with the surfacemounted chip.

2.3.1 Clock sources for the MC56F82748 DSC
Three options are available for clocking the MC56F82748 device:



Oscillator internal to the MC56F82748 chip —approximately 8 MHz.
8 MHz crystal
External clock input from Primary Tower Connector or the AUX Connector.
The internal oscillator is used to clock the MC56F82748 MCU immediately following reset. This is the
default operation. In this mode, the 0-ohm resistors at R4 and R10 allow the GPIOC0 and GPIOC1 pins
of the MC56F82748 MCU to be used as inputs or outputs.
To use an external crystal with the MC56F82748, 0-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-56F8200 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 MC56F82748, make sure the 0-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 0-ohm resistors at R10
allows the GPIOC1 pin of the MC56F82748 (pin 10) to be used as an input or output.
2.3.2 Serial I/O source select headers
The TWR-56F8200 board allows the UART functions of the MC56F82748 DSC to be connected to the
serial interface of the Primary Tower Connector J500A or through a USB bridge to the host PC using the
OSBDM/OSJTAG MCU (U6). The selection of the RXD connections is done as shown in Table 1. The
selection of the TXD connections is done as shown in Table 2.

As can be seen in the tables, the 56F82748 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 56F82748 DSC serial pins are not being used for the serial functions, the
shunts should be removed from those pins. For more information on the USB Serial Bridge function, see
USB serial bridge interface.
There are some tower boards available, such as TWR-SER that provide serial ports based on these
elevator connections. These boards can work with the TWR-56F8200, if configured and installed in the
same Tower system.
2.3.3 LEDs controlled by the MC56F82748 DSC
There are nine LEDs with buffers connected to the MC56F82748 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 each LED draws about 5 mA current. This table shows the DSC pin
names associated with each LED.

2.3.4 Motor control connector
The TWR-56F8200 board may be connected to a motor control board APMOTOR56F8000E. The motor
control connector (J501) is at the bottom of the board to provide a convenient connection to the motor
control board.

Freescale Semiconductor Inc.
Some of the MC56F82748 DSC pins are connected to the motor control connector. The pins associated
with analog inputs have 100 Ω resistors in series to provide some ESD protection for the analog inputs
of the DSC. The pins providing analog signals from the motor control board have 2200 pF capacitors
with the 100 Ω resistors to provide a low-pass filter. The connector pinout is shown in Table 4.

2.3.5 Auxiliary connectors
In addition to the motor control connector, the TWR-56F8200 board also provides two auxiliary
connectors J502 at the bottom of the board. These connectors provide access to the MC56F82748 DSC
signals that are not covered by the motor control connector. The pins associated with analog inputs have
100 Ω resistors in series to provide some ESD protection for the analog inputs of the DSC. The
connector pinout is shown in this table.

2.3.6 Tower system elevator connectors
The TWR-56F8200 board features two expansion card-edge connectors that interface to 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-56F8200 board, while the Secondary Elevator
connector only makes connections to ground (GND). Table 7 lists the pin functions for the Primary
Elevator Connector.
2.3.7 Thermistors as analog inputs
The TWR-56F8200 board provides four thermistors (RT1–RT4) near the corners of the board that can
be used as single-ended or differential analog inputs to the MC56F82748 DSC as can be seen on sheet 6
of the schematic (See Appendix B—TWR-56F8200 board schematic). In addition to each thermistor,
there is a resistor between the thermistor and P3_3V and another resistor between the thermistor and
ground. All the thermistors are 10 kΩ parts but the associated divider chain uses different resistors. This
makes the voltage across the thermistor larger or smaller and provides the ability to try the different gain
settings on the analog channels. All the four thermistor circuits are designed to provide useable
differential inputs over the temperature range of 90 °C to –20 °C. RT2 and RT4 both give a differential
voltage of ~1.65 V at 25 °C. RT1 gives a differential voltage of 0.10 V and RT3 gives a differential
voltage of 0.28 V at 25 °C.
In addition to the thermistor voltage divider chain, each thermistor has a 0.1 µF 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 Ω 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.
2.3.8 CAN transceiver
The TWR-56F8200 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/TXD1 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: The GPIOC11/CANTX/SCL1/TXD1 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 3.3 V 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 Ω parallel termination resistor, R560, may be connected between these nets by installing a
shunt on header J15.
2.3.9 IRQ or input push-buttons
The TWR-56F8200 board has two push-buttons (SW1 and SW2) that can be used to provide inputs or
interrupts to the DSC. Each has a 10 kΩ pullup resistor to P3_3V and a 0.1 µF capacitor to ground to
minimize bounce on the output.
The 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 purpose, it is best to
remove the shunt to the DSC so that the 0.1 µF 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/OSJTAG chip. It is
pulled to P3_3V by a 10 kΩ resistor. It may be pulled low by the push-button or by Q1 in response to a
high output from the OSBDM/OSJTAG chip (pin 1) on the TRESET_OUT net. The state of the
GPIOD4/RESET_B signal is provided to the OSBDM/OSJTAG chip through a voltage translator
(U504B). This buffer is powered by the P3_3V/5V power rail so that its input will remain highimpedance when there is no USB cable connected. The buffered RESET signal is provided to pin 33 of
the OSBDM/OSJTAG chip and is used by the OSBDM/OSJTAG program in that chip.

2.3.11
JTAG header and OSBDM/OSJTAG disconnect header
The TWR-56F8200 board includes an OSBDM/OSJTAG circuit as a debug interface to the C56F82748
DSC for normal purposes. If the user desires to use a different debugger connection, header J14 provides
a connection point for an external JTAG hardware 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
SBDM/OSJTAG circuit to the JTAG signals should be removed, allowing the external debugger to
control the JTAG port, rather than the JM60.
The TWR-56F8200 board provides a 2.2 kΩ pullup resistor to 3.3 V on the TMS line. If an external
JTAG hardware debugger also has a pullup on this line, the external debugger may not be able to pull
the TMS line low. If this happens, remove one of the pull up resistors on the TMS line.
2.4 OSBDM/OSJTAG
2.4.1 Debug interface
An onboard MC9S08JM60 based Open Source BDM (OSBDM/OSJTAG) circuit provides a debug
interface to the MC56F82748. A standard USB A male to mini-B male cable (supplied with the tower
card) can be used for debugging via the USB connector, J18.
2.4.2 USB serial bridge interface
The onboard MC9S08JM60 can also be used as a USB-to-serial bridge interface for the UART signals
from the MC56F82748 DSC. This bridge circuit is described in detail in Serial I/O source select headers.
The RXD_SEL signal goes to the MC56F82748 DSC. The USB bridge chip is powered by 5 V; so it has
a 5 V output. The buffer (U505) is able to accept the 5 V signal from the USB bridge chip (T_TXD1)
and converts it to the 3.3 V signal (RXD_SEL) for the DSC. The buffer 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 TWR
board, the RTS signal is not driven and the 3.3 V powered inverter (U502C) input is biased low
disabling the output of the buffer.
In a similar way, TXD_SEL is a 3.3 V signal from the MC56F82748 DSC. The USB bridge chip is
expecting a 5 V input on T_RXD1. The buffer between these two signals (U504C) is powered by
P3_3V/5V. It will accept the 3.3 V input from the DSC and convert it to the 5 V 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
5 V powered buffer is disabled; so nothing is driving the powered down USB bridge chip.
The serial interface signals from the MC56F82748 DSC may be routed to the MC9S08JM60 serial
interface via header and Berg straps. Using the USB serial bridge, the MC9S08JM60 will convert the
serial interface data into USB packets and send them to the host PC where they may be handled by a PC
application normally conversant with a serial port.

2.4.3 Clocking the OSBDM/OSJTAG MCU (MC9S08JM60)
The MC9S08JM60 MCU uses an onboard 4 MHz external crystal circuit (Y2, R16, C7, and C9) for its
clock. There are no user options for clocking the MC9S08JM60 MCU.
2.4.4 Reserved function select header
Header J20 selects whether the onboard MC9S08JM60 MCU operates as an OSBDM/OSJTAG debug
interface or as a USB Serial Bridge interface on older versions of S08 firmware such as may have
existed on prototypes of the TWR56F8200. Leaving the shunt on the header enables the
OSBDM/OSJTAG debug interface. Removing the shunt on header J20 enables the USB Serial Bridge
interface. The header J20 is subsequently reserved for future use.
2.4.5 Bootloader enable
In addition to the OSBDM/OSJTAG Debug interface and the USB Serial Bridge interface, the
MC9S08JM60 device used in the OSBDM/OSJTAG circuit is preprogrammed with a USB boot loader.
The USB boot loader 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/OSJTAG firmware to be upgraded by the user when upgrades become available. In normal
OSBDM/OSJTAG or USB Serial Bridge operation, this shunt must be left open. For details on the USB
boot loader, see USB Bootloader for the MC9S08JM60 (document number AN3561), available on
freescale.com.
The USB boot loader communicates with a GUI application running on a host PC. The GUI application
can be found on freescale.com using the search keyword “JM60 GUI”. See Section 2.5 “PC Driver and
PC GUI Tool,” and Section 3.3 “Running PC GUI Tool,” of USB Bootloader for the MC9S08JM60
(document number AN3561) for details on installing and running the application.
2.4.6 BDM header
The BDM header at J22 is used for initial programming of the MC9S08JM60 MCU or if reprogramming
when the boot loader fails. An external S08 BDM debugger would be connected to J22 and used to
program the MCU. This is not expected to be a normal user interface; however it is useful if the JM60
device is inadvertently reprogrammed with firmware that is not functional.
2.4.7 OSBDM/OSJTAG status LEDs
The MC9S08JM60 OSBDM/OSJTAG MCU controls two status LEDs at D12 and D13. See the
OSBDM/OSJTAG instructions for the meaning of the LEDs.
2.4.8 OSBDM/OSJTAG voltage translation
Since the OSBDM/OSJTAG MCU runs from 5 V and the 56F82748 DSC runs from 3.3 V, there needs
to be voltage translation between the two circuits. This is done through U505, U504A, and U502B.
U505 has 5 V tolerant inputs and provides 3.3 V 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 3.3 V
TDO signal from the DSC to a 5 V signal for the OSBDM/OSJTAG MCU. The outputs of both these
TWR-56F8200 Tower Board, Rev. 1, 10/2013
14
Freescale Semiconductor Inc.
translators are high-impedance if the signal OUT_EN_B goes high. This happens if the
OSBDM/OSJTAG circuit looses power (no power to the USB connector). In that case, the OUT_EN
signal from the OSBDM/OSJTAG MCU (pin 15) is biased low by R12. The inverter at U502B then
drives OUT_EN_B high in response. For additional information, see USB serial bridge interface.

6 Appendix A – Tower system elevator connector pin functions
Table 7 provides the pin out for the Primary Elevator Connector. An “X” in the “Used” column
indicates that there is a connection from the TWR-56F8200 board to that pin on the Elevator connector.
An “X” in the “Jmp” column indicates that a jumper is available that can isolate the onboard circuitry
from the Elevator connector.
The function listed in the “Usage” column is the function(s) that the pin is expected to provide when
used with the Tower system. All of the MC56F82748 pins (except power) have multiple functions. Not
all of the possible functions are shown.
Note that all analog pins (ANAn or ANBn) have a low-pass filter to ground consisting of a 100 ohm
resistor and a 2200 pF capacitor. This is to protect the analog inputs of the DSC from a static discharge
at one of the connectors. See schematic sheets 6 and 7 in Appendix B—TWR-56F8200 board schematic.
