AT80C31X2-3CSUM

MCU 8Bit 80C 8051 CISC ROMLess 3.3V/5V 40Pin PDIP Stick

Description

TS80C31X2 is high performance CMOS and ROMless versions of the 80C51 CMOS single chip 8-bit microcontroller. The TS80C31X2 retains all features of the TSC80C31 with 128 bytes of internal RAM, a 5-source, 4 priority level interrupt system, an o n-chip oscilator and two timer/counters. In addition, the TS80C31X2 has a dual data pointer,a more versatile serial channel

that facilitates multiprocessor communication EUART and a X2 speed improvement mechanism.
