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. The easy to use and easy to remember instruction set reduces development time significantly. The FM8P51 series consists of Power-on Reset (POR), Brown-out Reset (BOR), Power-up Reset Timer (PWRT), Oscillator Start-up Timer(OST), Watchdog Timer EPROM ROM, SRAM tri-state I/O port, I/O pull-high/open-drain control, Power saving SLEEP mode, 4 real time programmable Clock Counter Interrupt, SPI, RFC, data compare, Wake-up from SLEEP mode, and Code Protection for EPROM products. There are four Oscillator configurations to choose from, including the power-saving LP (Low Power) Oscillator and cost saving RC Oscillator The FM8P51 series address 4K13 of program memory. The FM8P51 series 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. By Unkown
