S1C33 FAMILY C33 PE CORE MANUAL

EPSON

1 Summary

The C33 PE is a RISC type processor in the S1C33 series of Seiko Epson 32-bit microcomputers.

The C33 PE (Processor Element) Core is a Seiko Epson original 32-bit RISC-type core processor for the S1C33

Family microprocessors. Based on the C33 STD Core CPU features, some useful C33 ADV Core functions/

instructions were added and some of the infrequently used ones in general applications are removed to realize a

high cost-performance core unit with high processing speed.

The C33 PE Core has been designed with optimization for embedded applications (full RTL design) in mind to

short development time and to reduce cost.

As the principal instructions are object-code compatible with the C33 STD Core CPU, the software assets that the

user has accumulated in the past can be effectively utilized.
