80C32/80C52/80C32E  
CMOS 0 to 36 MHz Single Chip 8–bit Microcontroller  
1. Description  
TEMIC’s 80C52 and 80C32 are high performance CMOS versions of the 8052/8032 NMOS single chip 8 bit  
Microcontroller.  
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 36 MHz with VCC = 5 V.  
D 80C32: Romless version of the 80C52  
D 80C32/80C52-12: 0 to 12 MHz  
D 80C32/80C52-30: 0 to 30 MHz  
D 80C32/80C52-36: 0 to 36 MHz  
D 80C32E-30: 0 to 30 MHz Radiation Tolerant
