   产品概述 返回TOPtfe嘉泰姆

The CX8PE59 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. The CX8PE59 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, 2 real time programmable clock/counter, Interrupt, IROUT, SPI, Wake-up from SLEEP mode, and Code Protection for EPROM products. There are four oscillator configurations to choose from, including the power-saving LP (Low Power) oscillator and cost saving RC oscillator. The CX8PE59 series address 4K×13 of program memory. The CX8PE59 series 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.
