Rev. E – July 03, 2000
CMOS 0 to 25 MHz Programmable 8–bit Microcontroller
Description
TEMIC’s TSC87C52 is high performance CMOS
EPROM version of the 80C52 CMOS single chip 8 bit
microcontroller.
The fully static design of the TSC87C52 allows to
reduce system power consumption by bringing the clock
frequency down to any value, even DC, without loss of
data.
The TSC87C52 retains all the features of the 80C52 with
some enhancement: 8 K bytes of internal code memory
(EPROM); 256 bytes of internal data memory (RAM);
32 I/O lines; three 16 bit timers one with count–down
and clock–out capability; a 6-source, 2-level interrupt
structure; a full duplex serial port with framing error
detection; a power off flag; and an on-chip oscillator.
The TSC87C52 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 TSC87C52 is manufactured using non volatile
SCMOS process which allows it to run up to:
D 25 MHz with VCC = 5 V ± 10%.
