TS83C51U2 - (TS80C51U2 - TS87C51U2) Double UART 8-bit CMOS Microcontroller

Download the TS83C51U2 datasheet PDF. This datasheet also covers the TS80C51U2 variant, as both devices belong to the same (ts80c51u2 - ts87c51u2) double uart 8-bit cmos microcontroller family and are provided as variant models within a single manufacturer datasheet.

General Description

TS80C51U2 is high performance CMOS ROM, OTP and EPROM versions of the 80C51 CMOS single chip 8-bit microcontroller.

Key Features

  • of the 80C51 with extended ROM/EPROM capacity (16 Kbytes), 256 bytes of internal RAM, a 7-source , 4-level interrupt system, an on-chip oscilator and three timer/counters. In addition, the TS80C51U2 has a second UART, enhanced functions on both UART, enhanced timer 2, a hardware watchdog timer, a dual data pointer, a baud rate generator and a X2 speed improvement mechanism. The fully static design of the TS80C51U2 allows to reduce system power consumption by bringing the clock frequency down to.

TS80C51U2 TS83C51U2 TS87C51U2 Double UART 8-bit CMOS Microcontroller 1. Description TS80C51U2 is high performance CMOS ROM, OTP and EPROM versions of the 80C51 CMOS single chip 8-bit microcontroller. The TS80C51U2 retains all features of the 80C51 with extended ROM/EPROM capacity (16 Kbytes), 256 bytes of internal RAM, a 7-source , 4-level interrupt system, an on-chip oscilator and three timer/counters. In addition, the TS80C51U2 has a second UART, enhanced functions on both UART, enhanced timer 2, a hardware watchdog timer, a dual data pointer, a baud rate generator and a X2 speed improvement mechanism. The fully static design of the TS80C51U2 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data.
