一.产品概述
The CX8PE55 CX8PXE57 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.

configurations to choose from, including the power-saving LP (Low Power) oscillator and cost saving RC oscillator.The CX8PE55 CX8PXE57 address 512×13 of program memory, and the CX8PE57/E57E address 2K×13 of program memory.The CX8PE55 CX8PXE57 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.
