FM8PS54 - (FM8PS54 / FM8PS56) EPROM/ROM-Based 8-Bit Microcontroller Series

Description

The FM8PS54/S56 series is a family of low-cost, high speed, high noise immunity, EPROM/ROM-based 8-bit CMOS microcontrollers.

It employs a RISC architecture with only 42 instructions.

All instructions are single cycle except for program branches which take two cycles.

Features
