CX8PB56B CX8PE54/E56系列是一系列低成本、高速、高抗噪、基于EPROM/ROM的8位CMOS微控制器。它采用了只有42条指令的RISC架构。所有指令都是单周期的，除了需要两个周期的程序分支。易于使用和记忆的指令集大大缩短了开发时间。
CX8PE54/E56系列包括上电复位（POR）、断电复位（BOR）、上电复位定时器（PWRT）、振荡器启动定时器（OST）、看门狗定时器、EPROM/ROM、SRAM、三态I/O端口、I/Opull高/开漏/下拉控制、省电睡眠模式、实时可编程时钟/计数器、中断、从睡眠模式唤醒，以及EPROM产品的代码保护。有三种振荡器配置可供选择，包括省电的LP（低功耗）振荡器和节省成本的RC振荡器。
程序存储器的CX8PE54/E54E地址512×13，程序存储器的CX8PE56/E56E地址1K×13。
CX8PE54/E56可以直接或间接寻址其寄存器文件和数据存储器。包括程序计数器在内的所有特殊功能寄存器都映射到数据存储器中。

产品概述 返回TOP
The CX8PB56B CX8PE54/E56 series is a family of low-cost, high speed, high noise immunity, EPROM/ROM-based 8-bitCMOS 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 development time significantly.
The CX8PB56B CX8PE54/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/Opull-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 CX8PE54/E54E address 512×13 of program memory, and the CX8PE56/E56E address 1K×13 of program memory.
The CX8PE54/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.
