SECTION 1
Preface
The EVB555 is an MPC555-based evaluation board that can be used for the develop-
ment and test of microcontroller systems. The MPC555 is a member of the Motorola
MPC500 PowerPC™ Risc microcontroller family. Beside its PowerPC core and the
internal memory subsystem it has a number of peripheral components (eg. 2 Analog-
to-Digital converters, 2 CAN controller modules, 2 Time Processor Units) onchip.
The EVB555 can be used to evaluate the capabilities of an MPC555-based microcon-
troller system. All special features of the MPC555 are supported. The evaluation board
is a development and test platform for software and hardware for the MPC555. It can
be used by software and hardware developers to test programs, tools or circuits with-
out having to develop a complete microcontroller system themselves.
The heart of the evaluation board is the MPC555. The processor can be operated in
”single chip mode” as well as using external resources. The EVB555 evaluation board
has 1 Mbyte RAM, 512 Kbyte flash memory, one port replacement unit and numerous
hardware expansion possibilities. To support development and test, the evaluation
board can be connected to logic analyzers, debuggers and emulators produced by dif-
ferent manufacturers.

SECTION 2
Technical Features of the EVB555
The following list summarizes the technical features of the EVB555 evaluation board.
The architecture of the board is displayed in Figure 2-1 on the following page.
• General advantages
— Full function range of the MPC555 can be used
— Microcontroller works with variable clock rate (up to 40 MHz)
• Memory
— Contains 1 Mbyte fast, synchronous SRAM (32-bit wide, burstable)
— 512 Kbyte external flash memory (32-bit wide, burstable)
• Configurability
— Convenient configuration of the PLL of the microcontroller
via a triple DIP switch
— Reset configuration of the MPC555 via a DIP switch (32 bits)
• Extensive analysis and debug support
— Flexible BDM interface (background debug mode) for debugging
— Direct connection to the ETAS emulator test probe ETKP-1
— Excellent analysis possibilities with 268-pin interface for
logic analyzers (6 AMP Mictor and 2 berg type connector)
— Connection of the probe to Lauterbach Trace32
emulation and programming system
• Very good expansion capability
— MAPI-400 interface
Interface as a connection to a customer-specific base-board
(user extension board)
— Customized communication expansion
Customer-specific expansion module, e.g. for CAN,
additional serial interfaces (RS232)
— Host communication expansion
Expansion module for high-speed communication to host system,
e.g. via Ethernet, Firewire
— Port replacement unit (PRU)
In ”external bus mode” 64 general purpose I/O pins are available
that are required by the MPC555 for the bus interface.
