Double UART 8-bit CMOS Microcontroller, 0-60 MHz

1. Description

TEMIC TS80C51U2 is high performance CMOS ROM, The fully static design of the TS80C51U2 allows to

OTP and EPROM versions of the 80C51 CMOS single reduce system power consumption by bringing the clock

chip 8-bit microcontroller.

frequency down to any value, even DC, without loss of

data.

The TS80C51U2 retains all features of the TEMIC

80C51 with extended ROM/EPROM capacity (16 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.

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.
