DESCRIPTION:
The C3 family are CPU mezzanine daughtercards based on IDT's MIPS
processors. The C3 Card family is designed to replace the CPU and specific
support circuitry around the CPU in a system design. The goal of the C3 is
to provide the system designer a seamless hardware migration path
through IDT's family of 64-bit MIPS processors(R4650, R4700, R64475,
R5000, R64575), and to simplify the overall system implementation require-
ments of those processors.
Each of the above processors has a unique pin configuration/package;
therefore, a system designer would normally be required to implement a
unique board design for each of the processors. The goal of the C3 is to
eliminate the differences between these processors at the system interface
level, and to allow the system designer to implement a single baseboard
design which will support C3 cards featuring the R4650, R4700, R64475,
R5000, R64575 or future processors.
