AT80C31X2-3CSUV中文资料8-bit CMOS Microcontroller ROMless数据手册Microchip规格书

描述 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.
