Chapter 1. M5407C3Board 1-1
Chapter 1
M5407C3 Board
The M5407C3 is a versatile single board computer based on MCF5407 ColdFire®
Processor. It may be used as a powerful microprocessor based controller in a variety of
applications. With the addition of a terminal, it serves as a complete microcomputer for
reference, development/evaluation, training and educational use. The user need only
connect an RS-232 compatible terminal (or a personal computer with terminal emulation
software) and power supply to have a fully functional system.
Provisions have been made to connect this board to additional user supplied peripherals, via
the Microprocessor Expansion Bus connectors, to expand memory and I/O capabilities.
Additional peripherals may require bus buffers to minimize additional bus loading.
Furthermore, provisions have been made in the PC-board to permit configuration of the
board in a way, which best suits, an application. Options available are: upgrade to
512MBytes SDRAM, 512K SRAM, and commercially available slave PCI devices.
1.1 General Hardware Description
The M5407C3 board provides the RAM, Flash ROM, on board NE2000 compatible
Ethernet interface (10M bit/sec), RS232, and all the built-in I/O functions of the MCF5407
for learning and evaluating the attributes of the microprocessor. The MCF5407 is a member
of the ColdFire® family of processors. It is a 32-bit processor with 32-bit of address bus
and 32 lines of data. The processor has eight 32-bit data registers, eight 32-bit address
registers, a 32-bit program counter, and a 16-bit status register.
The MCF5407 has a System Integration Module referred to as the SIM. The module
incorporates many of the functions needed for system design. These include programmable
chip-select logic, System Protection logic, General purpose I/O, and Interrupt controller
logic. The chip-select logic can select up to eight memory banks and peripherals in addition
to two banks of DRAM’s. The chip-select logic also allows programmable number of
wait-states to allow the use of slower memory (refer to
MCF5407 User's Manual by
Freescale for detailed information about the SIM.). The M5407C3 uses four (CS[3:0]) of
the eight chip selects to access the Flash ROM’s (CS0), PCI bridge chip (CS1), SRAM

General Hardware Description
to the user.
The M5407C3 will work with most PC100 SDRAM DIMMs with a few exceptions. The
MCF5407 supports up to two banks of SDRAM, but double-sided DIMMs require 4 bank
selects to access all of the chips. Therefore when using double-sided DIMMs only half of
the available memory will be accessible. Since DIMMs are manufactured primarily for use
in PCs the DQM signals on some DIMMS are routed so that the SDRAM can only be
accessed correctly as a 64-bit port so the M5407C3 will not be able to access the SDRAM
correctly.

System Memory
1.2 System Memory
One on board Flash ROM (U12) is used to store the M5407C3 dBUG debugger/monitor
firmware in the lower 128 KBytes. The AM29PL160C-XX device is 16Mbits (16 bit by 1
MByte) giving a total of 2MBytes of Flash memory.
The PCI bridge chip provides the interface to the Universal 32-bit PCI on board connector
allowing the user to experiment and develop new applications to commercially available
slave PCI based peripherals products.
The MCF5407 has 4KBytes of internal SRAM organized as two independently
configurable 2 Kbyte blocks. each block can be configured for either data or instruction
space.
There is one 168-pin DIMM socket for SDRAM. System ships with 1M x 8 Bank x 16-Bits
SDRAM totaling 16M of volatile memory. Various SDRAM configurations are supported.
The internal caches of the MCF5407 are non-blocking. The data cache is 8 KByte, 4-way
set-associative with a 16-byte line size. The instruction cache is 16 KBytes, 4-way
set-associative with a 16-byte line size. The ROM Monitor currently does not utilize the
caches, but programs downloaded with the ROM Monitor can use the cache.
The M5407C3 evaluation board has a foot print for 512 KByte SRAM but is unpopulated.
1.3 Serial Communication Channels
The MCF5407 has 2 built-in UART’s (UART0 and UART1) with independent baud rate
generators. The signals of both channels are passed through external Driver/Receivers to
make the channel compatible with RS-232.An RS232 serial cable with DB9 connectors is
included. UART0 (P4) is used by the debugger for the user to access with a terminal. In
addition, the signals of both channels are available on the 120 pin expansion connector J2.
UART0 channel is the “TERMINAL” channel used by the debugger for communication
with external terminal/PC. The “TERMINAL’baud rate defaults to 19200.
1.4 Parallel I/O Ports
MCF5407 offers one 16-bit general-purpose parallel I/O port. Each pin can be individually
programmed as input or output. The parallel port bits PP[7:0] are multiplexed with
TT[1:0], TM[2:0], DREQ[1:0], and XTIP. The second set of parallel port bits PP[15:8] is
multiplexed with address bus bits A[31:24]. Both bytes of the parallel port are controlled
by the Pin Assignment Register (PAR). The pins are programmable on a pin by pin basis.
The setting of the multiplexed pins is determined by the configuration byte during reset.
After reset, PP[7:0] are configured as parallel port output pins and the PP[15:8] are
configured as A[31:24]. PP[7:4] are general purpose outputs and PP[3:0] are used by the
ROM Monitor to automatically configure the SDRAM address lines via the U27 mux.

ProgrammableTimer/Counter
1.5 ProgrammableTimer/Counter
The MCF5407 has two built in general purpose timer/counters. These timers are available
to the user. The signals for each timer are available on the 120 pin expansion connector J2.
1.6 PCI Controller
The MCF5407 connects to the PCI controller (U17) via the PCI host interface. The PCI
controller is configured for master mode. U18 contains the arbitration logic for the PCI bus.
This logic is such that the PCI controller (U17) defaults to allowing the 5407 bus
mastership. A PCI card wishing to arbitrate the bus away from the controller must use
signal REQ# to request the bus. U18 will then arbitrate the bus away from U17 and assert
GNT# to the PCI card to show that the card has been granted the bus. Similarly the
controller can arbitrate the bus back using signals /REQ and /GNT. By default the controller
currently has priority over the card in the equations in U18, if the user wanted to alter this
priority they could do so by editing file "ISA5407.abl" available on the ColdFire website
(www.mot.com/coldfire).
1.7 On Board Ethernet
The M5407C3 has an on board Ethernet (NE2000 compatible controller) operating at 10M
bits/sec. The on board dBUG ROM monitor is programmed to allow a user to download
files from a network to memory in different formats. The current compiler formats
supported are S-Record, COFF, ELF, or Image. Refer to Appenix A for details on how to
configure.
1.8 System Configuration
The M5407C3 board requires only the following items for minimum system configuration:

Installation And Setup
1.9.3 Providing Power to the Board
The board accepts two means of power supply connections. Connector P6 is a 2.1mm
power jack and P3 lever actuated connector. The board accepts 7V to 14V DC at 1.5 Amp
via either one of the connectors.
1.9.4 SelectingTerminal Baud Rate
The serial channel of MCF5407 which is used for serial communication has a built in timer
used by the dBUG ROM monitor to generate the baud rate used to communicate with a
terminal.. It can be programmed to a number of baud rates. After the power-up or a manual
RESET, the dBUG ROM monitor firmware configures the channel for 19200 baud. After
the dBUG ROM monitor is running, you may issue the SET command to choose any baud
rate supported by the dBUG ROM monitor. Refer to Chapter 2 for the discussion of this
command.
1.9.5 The Terminal Character Format
The character format of the communication channel is fixed at the power-up or RESET.
The character format is 8 bits per character, no parity, and one stop bit. You need to insure
that your terminal or PC is set to this format.
1.9.6 Connecting theTerminal
The board is now ready to be connected to a terminal. Use the RS-232 male/female DB-9
serial cable to connect the PC to the M5407C3. The cable has a 9-pin female D-sub
terminal connector at one end and a 9-pin male D-sub connector at the other end. Connect
the 9-pin male connector to P4 connector on M5407C3. Connect the 9-pin female
connector to one of the available serial communication channels normally referred to as
COM1 (COM2, etc.) on the IBM PC’s or compatible. Depending on the kind of serial
connector on the back of your PC, the connector on your PC may be a male 25-pin or 9-pin.
You may need to obtain a 9-pin-to-25-pin adapter to make the connection. If you need to
build an adapter, refer to Figure 2 which shows the pin assignment for the 9-pin connector
on the board.
1.9.7 Using a Personal Computer as aTerminal
You may use your personal computer as a terminal provided you also have a terminal
emulation software such as PROCOMM, KERMIT, QMODEM, Windows 95/98/2000
