1 Overview
TWR-MCF51MM is a low-cost evaluation, demonstration and development board that features a 32-bit MCF51MM256 microcontroller. The TWR-MCF51MM can operate stand-alone or as the main control board in a Tower System with peripheral modules.
The following list summarizes the features of the MCF51MM Tower MCU boards:
Tower compatible processor board Open Source BDM (OSBDM) circuit Analog measurement circuitry 4 LEDs DIP Switches and push buttons for user input Potentiometer MMA7361L three-axis accelerometer RS232 transceiver and 2x5 pin header

3 Hardware Features
This section provides more details about the features and functionality of the TWR-MCF51MM.
3.1 Clocking
Two crystals are provided on the board for clocking the MCF51MM256 device:
1. A 16 MHz crystal connected to XTAL2 and EXTAL2 for system clocking
2. A 32.768kHz crystal connected to XTAL1 and EXTAL1 for TOD usage
3.2 System Power
The TWR-MCF51MM can be powered by the Open Source BDM (OSBDM) circuit via the Mini-B USB connector when stand-alone. When assembled with the Tower System and the TWR-SER is configured to run USB device mode (J16 pin 3 and 4 connected), the Mini-B USB connector is no longer used as a power source and only used for OSBDM debugging purposes. In this case, the power will be supplied from the Mini-B USB from the TWR-SER. Please plug in the Mini-B USB connector from TWE-SER before plugging in the Mini-B USB connector from TWR-MCF51MM.
A standard USB A male to Mini-B male cable (provided) can be used to supply power from a USB host or powered USB hub. Optionally, an AC to DC adapter with a USB A female receptacle (not provided) can be used as the power source.
A jumper, J11, can be used to isolate the 3.3V supply from the microcontroller. This connection can be used to measure the power usage of the MCF51MM256 microcontroller.
3.3 Debug Interface
An on-board, MC9S08JM60 based OSBDM circuit provides a debug interface to the MCF51MM256. A standard USB A male to Mini-B male cable (provided) can be used for debugging via the USB connector, J17. Refer to Section 6 for information on other modes of operation of the OSBDM.

3.4 RS232 Interface
An RS232 transceiver on the TWR-MCF51MM connects to a standard 2x5 pin header (refer to Figure 2). Selection jumpers J15 and J16 allow MCF51MM256 SCI2 signals to be routed to either the RS232 transceiver or the OSBDM circuit. Refer to Figure 5 for more details.
Alternatively, when assembled as a Tower System, the MCF51MM256 SCI1 TX and RX are routed to the SER-TWR. If the SER-TWR jumpers are configured to run in RS-232 mode, the SCI1 TX and the RX signal can be communicated via the RS232 connector from the TWR-SER. Please refer to the TWE-SER user manual (TWRSERUM) from www.freescale.com/tower for more detail.
Figure 2. RS232 2x5 Pin Header Connections
3.5 Infrared Port
The TWR-MCF51MM implements an infrared transmit and receive port. The transmit circuit is implemented with an infrared diode and the user can choose to drive the diode either with IRO or SCI TX. The receiver is implemented by an infrared transistor and the user can choose to input this signal to the SCI RX or the ACMP input. Jumpers J9, J25 and J26 are used for routing the connections, refer to Section 4 to set the jumpers. Please refer to application note AN4116, searchable from www.freescale.com
3.6 Medical Connector
The TWR-MCF51MM features a 2x10 expansion connector J27 (refer to Figure 3) to MED-EKG for routing the medical engine signals to external medical board so it can use the OPAMP, TRIAMP, ADC and DAC on MCF51MM to implement the requirement signal conditioning for medical applications.
When the DSC MC56F8006 from the MED-EKG is enabled, MCF51MM256 can choose to read the conditioned EKG results output from the DSC via I2C transmission (pin 3 and pin 4). To enable I2C communication, you must assemble the MEG-EKG with the Tower System because the TWR-SER has the pulled up resistors circuit required for I2C transmission.
In Figure 3, the bold text highlights the functions that are used to implement the MED-EKG demonstration. For detail about the MED-EKG, please refer to the MED-EKG user manual, MED-EKG lab and schematic included in the TWR-MCF51MM-KIT or TWR-S08MM128-KIT. All these are also available on Freescale.com/tower

3.7 Elevator Connections
The TWR-MCF51MM 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-MCF51MM, while the Secondary Elevator connector only makes connections to ground (GND). Figure 4 provides the pinout for the Primary Elevator connector. An “X” in the “Used” column indicates that there is a connection from the TWR-MCF51MM to that pin on the elevator connector. An “X” in the “Jmp” column indicates that a jumper is available that can configure or isolate the connection from the elevator connector.

5 Input/Output Connectors and Pin Usage Table
The following tables provide details on which MCF51MM256 pins are communicating with the TWR­MCF51MM sensors, LEDs, switches and other I/O interfaces.
Figure 6. I/O Connectors and Pin Usage Table
6 OSBDM
An on-board, MC9S08JM60 based OSBDM circuit provides a debug interface to the MCF51MM256. The MC9S08JM60 is a USB-enabled microcontroller with an 8-bit HC9S08 core. The OSBDM circuit provides a USB-to-debug interface that allows run-control and debugging of the MCF51MM256 target device. The USB drivers required to communicate with the OSBDM are provided in development tools such as Freescale CodeWarrior. When TWR-MCF51MM is used stand-alone, this single USB connection can also be used for power.
6.1 Bootloader Mode For MC9S08JM60
The MC9S08JM60 device used in the OSBDM circuit is preprogrammed with OSBDM debugger firmware and a USB Bootloader. The bootloader mode can be used to update the OSBDM debugger firmware if an update becomes available. Jumper J12 determines which application will run following a power-on reset. If the Bootloader Mode is chosen (jumper shunt on J12), the bootloader will be

executed, allowing in-circuit reprogramming of the JM60 flash memory via USB. Refer to Application
Note AN3561 on the Freescale website (http://www.freescale.com) for details on the USB Bootloader.
The USB Bootloader communicates with a GUI application running on a host PC. The GUI application can be found on the Freescale website; 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.
7 Bootloader Mode For MCF51MM256
Unlike MC9S08JM60, MCF51MM256 has an on-chip ROM based USB bootloader that allows the MCF51MM256 for mass erase and programming via its USB interface. This on-chip bootloader does not consume user flash space. To enable USB bootloader mode for MCF51MM256, on the TWR-MCF51MM module, set SW3 DIP switch 2 and 3 to position 3, as indicated in Figure 7. NOTE: Under normal development you will need to set SW3 DIP switch 2 and 3 to position 2.

8 BDM inteface (Optional)
Both MCF51MM256 and MC9S08JM60 have an on-chip background debug module. The user can choose to bypass the USB OSBDM interface and use the BDM interface for debugging and programming the corresponding chip instead. The BDM interface for MCF51MM256 is at J13 header and MC9S08JM60 is at J14 from the TWR-MCF51MM module. The user needs a P&E USB BDM MULTILINK in order to use this interface. This is a repeat function of the OSBDM and is not required.
