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.

The TS80C51U2 has 2 software-selectable modes of

reduced activity for further reduction in power

consumption. In the idle mode the CPU is frozen while

the timers, the serial port and the interrupt system are still

operating. In the power-down mode the RAM is saved

and all other functions are inoperative.

(window), CDIL40 (window)

3. The second UART

In this document, UART_0 will make reference to the

first UART (present in all Atmel Wireless &

Microcontrollers C51 derivatives) and UART_1 will

make reference to the second UART, only present in

the TS80C51U2 part.

The second UART (UART_1) can be seen as an alternate

function of Port 1 (P1.2 or P1.6 for RXD1 and P1.3 or

P1.7 for TXD1) or can be connected to (pin6 or pin12)

and (pin28 or pin34) of 44-pin package (see Pin
