EPROM/ROM-Based 8-Bit Microcontroller Series CX8PE54 CX8PE56family of low-cost, high speed, high noise immunity, EPROM/ROM-based 8-bit CMOS microcontrollers

   产品概述 返回TOPfoV嘉泰姆

The CX8PE54/CX8PE56 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 42 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 develoCXent time significantly. The FM8PE54/E56 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/pull-down control, Power saving SLEEP mode, real time programmable clock/counter, Interrupt, Wake-up from SLEEP mode, and Code Protection for EPROM products. There are three oscillator configurations to choose from, including the power-saving LP (Low Power) oscillator and cost saving RC oscillator. The FM8PE54/E54E address 512×13 of program memory, and the FM8PE56/E56E address 1K×13 of program memory. The FM8PE54/E56 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.
