P87C58X2BBD集成電路（IC）的微控制器規(guī)格書(shū)PDF中文資料

DESCRIPTION

The Philips microcontrollers described in this data sheet are high-performance static 80C51 designs incorporating Philips’ high-density CMOS technology with operation from 2.7 V to 5.5 V.

They support both 6-clock and 12-clock operation. The 8xC31X2/51X2 and 8xC32X2/52X2/54X2/58X2 contain 128 byte RAM and 256 byte RAM respectively, 32 I/O lines, three 16-bit counter/timers, a six-source, four-priority level nested interrup structure, a serial I/O port for either multi-processor communications, I/O expansion or full duplex UART, and on-chip

oscillator and clock circuits.
