80C32-12D

Manufacturer Part Number
80C32-12D
Description
CMOS 0 to 44 MHz Single-chip 8 Bit Microcontroller
Manufacturer
TEMIC [TEMIC Semiconductors]
Datasheet
MATRA MHS
CMOS 0 to 44 MHz Single-chip 8 Bit Microcontroller
Description
MHS’s 80C52 and 80C32 are high performance CMOS
versions of the 8052/8032 NMOS single chip 8 bit C.
The fully static design of the MHS 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. MHS’s 80C52/80C32 are manufactured
using SCMOS process which allows them to run from 0
up to 44 MHz with Vcc = 5 V.
MHS’s 80C52 and 80C32 are also available at 16 MHz
with 2.7 V < V
* 0 to 70 C temperature range.
For other speed and temperature range availability please consult your
sales office.
