1. General Description
The AM8EB051A 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 AM8EB051A provides powerful and easy useful instruction sets that can directly or indirectly address its register files and data memory.
1.1 Features
?? Wide operating voltage range:
- Four oscillator periods: 2.0 ~ 5.5V at 32kHz, 2.2 ~ 5.5V at DC-4MHz, 2.6 ~ 5.5V at DC-20MHz.
- Two oscillator periods: 2.0 ~ 5.5V at 32kHz, 2.2 ~ 5.5V at DC-8MHz, 10MHz-16MHZ, 20MHZ not used.
?? Wide operating frequency range: 32kHz ~ 20MHz.
?? Wide operating temperature range: 0ºC ~ 70ºC.
?? ROM: 1K x 14 bits.
?? RAM: 48 x 8 bits.
