FM8P51 - EPROM/ROM-Based 8-Bit Microcontroller

The FM8P51 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 47 instructions.

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