TSC80C31/80C51
CMOS 0 to 44 MHz Single-Chip 8 Bit Microcontroller
Description
The TSC80C31/80C51 is high performance SCMOS In addition, the TSC80C31/80C51 has two
versions of the 8051 NMOS single chip 8 bit µC.
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 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.
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.
