CMB2103 Features
Section 1 Introduction
This user’s manual explains connection, configuration, and operation information for the
MMCCMB2103 Controller and Memory Board (CMB2103), a development tool of Motorola’s
M•CORE™family. The CMB2103 lets you develop code to be embedded in an MMC2103
microcontroller unit.
As a standalone tool, the CMB2103 uses an RS232 connection to your computer. This connection
lets you use Motorola’s M•CORE System Development Software (SysDS) or the GNU
source-level debugger. The SysDS consists of a loader, the Picobug monitor, and a built-in selftest.
The CMB2103 also has a OnCE™ connector, enabling you to use a debugging application that
requires one.
Optionally, you may use the CMB2103 with a different emulator product, such as the Motorola
Embedded Background Debug Interface (EBDI).
Motorola's SysDS loader lets you download your code into the CMB2103's SRAM (for execution)
or FLASH memory (for execution or for storage in non-volatile memory).
The CMB2103 will combine easily with other, optional development boards from Motorola, such
as the MPFB1200 Platform Board. Such an optional board expands CMB2103 capacity, enhances
CMB2103 performance, or adds to CMB2103 features.
1.1 CMB2103 Features
The CMB2103 features:
•MMC2103 resident MCU (a development version, in a 160-pin PQFP package).
•2 megabytes FLASH memory.
•2 megabytes FSRAM (fast static RAM), configurable for 8-, 16-, or 32-bit operations.
•Address decode logic.
•Power supply that converts line power to 12-volt input power.
•Two RS232 serial communication ports.
•An ETAS ETK connector, for use with an ETKP1 probe.
•A CAN communications port.
• A J1850 communications port.
•OnCE connector.
•Four user-accessible LEDs.
•Three DIP switches: two for system configuration, one for firmware selection.

Introduction
•Two user prototyping (breadboard) areas.
•A modular, all-purpose interface (MAPI) 400 connector ring, on the top and bottom of the
CMB2103, for easy connection to other, compatible development boards.
•Three 38-pin Mictor logic analyzer connectors.
•Motorola's System Development Software (SysDS).
•GNU source-level debugger (from the Free Software Foundation).
•Eyelets for connections to MMC2103 peripherals.
•If your CMB2103 is part of an evaluation system (EVS) kit, it comes with a port
replacement unit board (PRUB), which section 5 of this manual explains. The evaluation
system kit also includes an MPFB1200 platform board, which comes with its own user’s
manual.
1.2 System and User Requirements
You need an IBM PC or compatible computer, running the Windows 95 or WindowsNT (version
4.0) operating system. The computer requires a Pentium (or equivalent) microprocessor, 16
megabytes of RAM, 50 megabytes of free hard-disk space, an SVGA color monitor, and an RS232
serial-communications port. To use the Picobug debug monitor, you also need Hyperterminal or a
comparable terminal-emulation program.
To get the most from your CMB2103, you should be an experienced C or M•CORE assembly
programmer.
Your CMB2103 requires 12-volt input power, at 0.5 amperes. The power supply that comes with
your CMB2103 provides this voltage from line power.
1.3 CMB2103 Layout
Figure 1-1 shows the layout of the CMB2103. Jumper header W1 specifies the chip select for
memory-mapped I/O(MMIO) device. Jumper header W2 specifies the FLASH chip select. Jumper
header W3 specifies the FSRAM chip select. Jumper header W4 specifies the ETK chip select.
Jumper header W6 selects either of two automotive-electronic communication protocols: CAN or
J1850. Jumper header W7 activates or deactivates the RS232 communications driver of the
resident MCU.

Introduction
The CMB2103 has twoprototyping areas. The smaller, squarish area is at the left edge of the board.
The 3.3-volt and ground connections are the partial columns of holes on the left and right of this
area. The 5-volt connections are the partial row of holes on the bottom of this area.
The larger, rectangular prototyping area is at the right edge of the CMB2103. The 3.3-volt and
5-volt connections are the top and bottom rows of holes; the ground connections are the partial
column of holes at the right.
Note the two groups of eyelets between each prototyping area and the adjacent MAPI connector.
(In Figure 1-1, a dashed rectangle encloses each eyelet group.) The eyelets are convenient points
for connection to peripheral signals likely to be used in prototyping.
Location F1 is for the CMB2103 fuse.
The resident MCU, at location U8, is an MMC2103 device, in a special, 160-pin PQFP package.
Table 1-1 lists CMB2103 specifications.
NOTE: The factory ships separate rubber feet with your CMB2103. If you will use
the CMB2103 as a standalone board, attach the feet to the underside
corners, for extra stability. If you will attach the CMB2103 to another
development board, leave the feet off the CMB2103.

Configuration
2.1.1 Setting the MMIO Chip Select Header (W1)
Jumper header W1 specifies the chip select for the memory-mapped I/O (MMIO) subsystem. The
diagram below shows thefactory configuration: the jumper betweenW1 pins 5 and6 specifies chip
select 3.
Alternatively, you can select chip select 1, 2, or 4 for MMIO by repositioning the W1 jumper,
respectively, to pins 1 and 2, 3 and 4, or 7 and 8.

Configuring Board Components
2.1.2 Setting the FLASH Chip Select Header (W2)
Jumper header W2 specifies the FLASH chip select. The diagram below shows the factory
configuration: The jumper between W2 pins 1 and 2 specifies chip select 1 for FLASH memory.
Alternatively, you can select chip select 2, 3, or 4 for FLASH memory by repositioning the W2
jumper, respectively, to pins 3 and 4, 5 and 6, or 7 and 8.
NOTE: Each chip-select header, W1 through W4, must specify a different chip
select. Do not install multiple jumpers in any of these headers.
2.1.3 Setting the FSRAM Chip Select Header (W3)
Jumper header W3 specifies the FSRAM chip select. The diagram below shows the factory
configuration: the jumper between W3 pins 3 and 4 specifies chip select 2 for FSRAM.
Alternatively, you can select chip select 1, 3, or 4 for FSRAM by repositioning the W3 jumper,
respectively, to pins 1 and 2, 5 and 6, or 7 and 8.
NOTE: Each chip-select header, W1 through W4, must specify a different chip
select. Do not install multiple jumpers in any of these headers.

2.1.4 Setting the ETK Chip Select Header (W4)
Jumper header W4 specifies the ETK chip select. This chip select is connected to the
general-purpose chip-select pin of the ETK connector. (This is pin 78 of connector J5, the
SGCSM_b pin.) The diagram below shows the factory configuration: the jumper between W4 pins
7 and 8 specifies chip select 4.
Alternatively, you can select chip select 1, 2, or 3 for the ETK connector by repositioning the W4
jumper, respectively, to pins 1 and 2, 3 and 4, or 5 and 6.
NOTES: 1. Each chip-select header, W1 through W4, must specify a different chip
select. Do not install multiple jumpers in any of these headers.
2. Use caution about connecting anything to the ETK connector if you also
connect your CMB2103 to an MPFB1200 platform board. Such a
connection through the ETK interface could interfere with platform-board
operation.

2.1.5 Setting the Automotive Interface Header (W6)
Jumper header W6 specifies either of two automotive-electronics interfaces. The diagram below
shows the factory configuration: the jumpers between pins 1 and 3, and between pins 2 and 4,
specify the J1850 interface, activating J1850 communications connector J52.
Alternatively, you may specify the CAN interface, activating CAN communications connector
J58, by repositioning the W6 jumpers between pins 3 and 5, and between pins 4 and 6.
2.1.6 Setting the RS232 Header (W7)
Jumper header W7 activates or deactivates the RS232 I/O ports (connectors J60 and J61). The
diagram below shows the factory configuration: the four jumpers activate the two ports.
Instead of using connectors J60 and J61, you may want to connect processor serial ports to the
target, via the MAPI connectors. This alternative communication requires you to deactivate the
RS232 I/O ports, by removing all the jumpers from header W7.
