一.产品概述2EQ嘉泰姆

The CX8PE55 CX8PXE57 series is a family of low-cost, high speed, high noise immunity, EPROM/ROM-based 8-bit2EQ嘉泰姆

CMOS microcontrollers. It employs a RISC architecture with only 47 instructions. All instructions are single cycle2EQ嘉泰姆

except for program branches which take two cycles. The easy to use and easy to remember instruction set reduces2EQ嘉泰姆

development time significantly.2EQ嘉泰姆

The CX8PE55 CX8PXE57 series consists of Power-on Reset (POR), Brown-out Reset (BOR), Power-up Reset Timer2EQ嘉泰姆

(PWRT), Oscillator Start-up Timer(OST), Watchdog Timer, EPROM/ROM, SRAM, tri-state I/O port, I/O2EQ嘉泰姆

pull-high/open-drain/pull-down control, Power saving SLEEP mode, real time programmable clock/counter,2EQ嘉泰姆

Interrupt, Wake-up from SLEEP mode, and Code Protection for EPROM products. There are four oscillator2EQ嘉泰姆

configurations to choose from, including the power-saving LP (Low Power) oscillator and cost saving RC oscillator.2EQ嘉泰姆

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

The CX8PE55 CX8PXE57 can directly or indirectly address its register files and data memory. All special function registers2EQ嘉泰姆

including the program counter are mapped in the data memory.  2EQ嘉泰姆
