AT83C5121 概述

T8xC5121 is a high performance CMOS ROM/CRAM derivative of the 80C51 CMOS
single chip 8-bit microcontrollers.
T8xC5121 retains the features of the Atmel 80C51 with extended ROM capacity (16
Kbytes), 512 bytes of internal RAM, a 4-level interrupt system, two 16-bit timer/counters
(T0/T1), a full duplex enhanced UART (EUART) with baud rate generator (BRG) and an
on-chip oscillator.
In addition, the T8xC5121 have, a Multi protocol Smart Card Interface, a dual data
pointer, 2 programmable LED current sources (2-4-10 mA) and a hardware Watchdog.
T89C5121 Flash RAM version and T85C5121 Code RAM version can be loaded by In-
System Programming (ISP) software residing in the on-chip ROM from a low-cost external
serial EEPROM or from R232 interface.
T8xC5121 have 2 software-selectable modes of reduced activity for further reduction in
power consumption.
