80C32/80C52
CMOS 0 to 44 MHz Single Chip 8–bit Microntroller
Description
TEMIC’s 80C52 and 80C32 are high performance CMOS
versions of the 8052/8032 NMOS single chip 8 bit
µC.
The fully static design of the TEMIC 80C52/80C32
allows to reduce system power consumption by bringing
the clock frequency down to any value, even DC, without
loss of data.
The 80C52 retains all the features of the 8052 : 8 K bytes
of ROM ; 256 bytes of RAM ; 32 I/O lines ; three 16 bit
timers ; a 6-source, 2-level interrupt structure ; a full
duplex serial port ; and on-chip oscillator and clock
circuits. In addition, the 80C52 has 2 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 80C32 is identical to the 80C52 except that it has no
on-chip ROM. TEMIC’s 80C52/80C32 are manufactured
using SCMOS process which allows them to run from 0
up to 44 MHz with Vcc = 5 V.
TEMIC’s 80C52 and 80C32 are also available at 16 MHz
with 2.7 V < V
CC
< 5.5 V.
