80C32/80C52
CMOS 0 to 44 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

D 80C32/80C52-12: 0 to 12 MHz

D 80C32/80C52-20: 0 to 20 MHz

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 < VCC < 5.5 V.

RD (external Data Memory read strobe)
Port 3 can sink/source three LS TTL inputs. It can drive CMOS inputs without external pullups.
5.7. RST
A high level on this for two machine cycles while the oscillator is running resets the device. An internal pull-down
resistor permits Power-On reset using only a capacitor connected to VCC. As soon as the Reset is applied (Vin), PORT
1, 2 and 3 are tied to one. This operation is achieved asynchronously even if the oscillator does not start-up.
5.8. ALE
Address Latch Enable output for latching the low byte of the address during accesses to external memory. ALE is
activated as though for this purpose at a constant rate of 1/6 the oscillator frequency except during an external data
memory access at which time one ALE pulse is skipped. ALE can sink/source 8 LS TTL inputs. It can drive CMOS
inputs without an external pullup.
5.9. PSEN
Program Store Enable output is the read strobe to external Program Memory. PSEN is activated twice each machine
cycle during fetches from external Program Memory. (However, when executing out of external Program Memory, two
activations of PSEN are skipped during each access to external Data Memory). PSEN is not activated during fetches
from internal Program Memory. PSEN can sink/source 8 LS TTL inputs. It can drive CMOS inputs without an external
pullup.
5.10. EA
When EA is held high, the CPU executes out of internal Program Memory (unless the Program Counter exceeds 1
FFFH). When EA is held low, the CPU executes only out of external Program Memory. EA must not be floated.
5.11. XTAL1
Input to the inverting amplifier that forms the oscillator. Receives the external oscillator signal when an external
oscillator is used.
Output of the inverting amplifier that forms the oscillator. This pin should be floated when an external oscillator is used.
