一.产品概述aDo嘉泰姆

The CX8PE55 CX8PXE57 series is a family of low-cost, high speed, high noise immunity, EPROM/ROM-based 8-bitaDo嘉泰姆

CMOS microcontrollers. It employs a RISC architecture with only 47 instructions. All instructions are single cycleaDo嘉泰姆

except for program branches which take two cycles. The easy to use and easy to remember instruction set reducesaDo嘉泰姆

development time significantly.aDo嘉泰姆

The CX8PE55 CX8PXE57 series consists of Power-on Reset (POR), Brown-out Reset (BOR), Power-up Reset TimeraDo嘉泰姆

(PWRT), Oscillator Start-up Timer(OST), Watchdog Timer, EPROM/ROM, SRAM, tri-state I/O port, I/OaDo嘉泰姆

pull-high/open-drain/pull-down control, Power saving SLEEP mode, real time programmable clock/counter,aDo嘉泰姆

Interrupt, Wake-up from SLEEP mode, and Code Protection for EPROM products. There are four oscillatoraDo嘉泰姆

configurations to choose from, including the power-saving LP (Low Power) oscillator and cost saving RC oscillator.aDo嘉泰姆

The CX8PE55 CX8PXE57 address 512×13 of program memory, and the CX8PE57/E57E address 2K×13 of program memory.aDo嘉泰姆

The CX8PE55 CX8PXE57 can directly or indirectly address its register files and data memory. All special function registersaDo嘉泰姆

including the program counter are mapped in the data memory.  aDo嘉泰姆
