The CME0555 is a development system for the Motorola MPC555 PowerPC Microcontroller. The
system is Plug and Play with the supplied Axiom Monitor provided in on-board PROM, 128K x 32
(512K bytes) Fast SRAM, 128K x 32 (512K bytes) minimum external Flash EPROM, Serial Cable,
9v 500ma Wall Plug, printed hardware manual and the MPC5xx support CD with programming
utilities, support software, source codes and technical manuals. Compatible with all MPC555 C
compilers and tool suites for application development.

The Axiom development system provides for low cost software testing with the use of the Monitor
in the on-board EPROM. Operations allow the user to load code in the On-Board RAM, Execute
application, and display or modify registers or memory. After code is operational the user may
relocate the code and reprogram the MPC555 Internal Flash EEprom or the boards fixed flash
for dedicated operation of new software. No additional hardware or software is required to operate.
For high level debug, extensive tools are available for the PowerPC core and the Debug Port is
available to connect a background debugger.
