TECHNOLOGY
FM8PA76
GENERAL DESCRIPTION
The FM8PA76 is a family of low-cost, high speed, high noise immunity, EPROM-based 8-bit CMOS microcontrollers.
It employs a RISC architecture with 54 instructions. All instructions are single cycle except for program branches
which take two cycles. The easy to use and easy to remember instruction set reduces development time
significantly.
The FM8PA76 consists of Power-on Reset (POR), Brown-out Reset (BOR), Power-up Reset Timer (PWRT),
Watchdog Timer, EPROM, SRAM, tri-state I/O port, I/O pull-high control, Power saving SLEEP mode, 5 real time
programmable clock/counter, Interrupt, Wake-up from SLEEP mode, and Code Protection for EPROM products.
There are eight oscillator configurations to be chosen from, including the power-saving LP (Low Power) oscillator
and cost saving internal RC oscillator.
The FM8PA76 address 2K×16 of program memory.
The FM8PA76 can directly or indirectly address its register files and data memory. All special function registers
including the program counter are mapped in the data memory.
The FM8PA76 provides total 9 channel 12bit AD converter with ±2LSB resolution.
