MHS’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 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

< 5.5 V.
