80C32/80C52
CMOS 0 to 44 MHz Single Chip 8鈥揵it Microcontroller
1. Description
TEMIC鈥檚 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

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鈥檚
80C52/80C32
are
manufactured using SCMOS process which allows them
to run from 0 up to 44 MHz with VCC = 5 V.
TEMIC鈥檚 80C52 and 80C32 are also available at
16 MHz with 2.7 V < VCC < 5.5 V.
