The AM8EB151A is a family of low-cost, high speed, high noise immunity and EPROM-embedded 8-bit CMOS
micro-controllers. It employs a RISC architecture with only 55 instructions. All instructions are single cycle except
for program branches that take two cycles. The AM8EB151A provides powerful and easy useful instruction sets
that can directly or indirectly address its register files and data memory.
