TSC80C31/80C51

CMOS 0 to 44 MHz Single-Chip 8 Bit Microcontroller

Description

The TSC80C31/80C51 is high performance SCMOS

versions of the 8051 NMOS single chip 8 bit µC.

The fully static design of the TSC80C31/80C51 allows to

reduce system power consumption by bringing the clock

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

data.

The TSC80C31/80C51 retains all the features of the 8051

: 4 K bytes of ROM ; 128 bytes of RAM ; 32 I/O lines ;

two 16 bit timers ; a 5-source, 2-level interrupt structure

; a full duplex serial port ; and on-chip oscillator and clock

circuits.

In addition, the TSC80C31/80C51 has two

software-selectable modes of reduced activity for further

reduction in power consumption. In the Idle Mode the

CPU is frozen while the RAM, the timers, the serial port,

and the interrupt system continue to function. In the

Power Down Mode the RAM is saved and all other

functions are inoperative.

The TSC80C31/80C51 is manufactured using SCMOS

process which allows them to run from 0 up to 44 MHz

with VCC = 5 V. The TSC80C31/80C51 is also available

at 20 MHz with 2.7 V < Vcc < 5.5 V.
