ST7293
1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST7293 is a HCMOS microcontroller unit
(MCU) from the ST7 family. It is based around an
industry standard 8 bit core and offers an en-
hanced instruction set. The processor runs with an
external clock at 8MHz with a 5V supply and
4MHz with a 3.0V supply. Due to the fully static
design of this device, operation down to DC is
possible. Under software control the ST7293 can
be placed in WAIT or HALT mode thus reducing
power consumption. The enhanced instruction set
and addressing modes afford real programming
potential. In addition to standard 8 bit data man-
agement the ST7293 features true bit manipula-
tion, 8x8 unsigned multiplication and indirect ad-
dressing modes. The device includes an on-chip
oscillator, CPU, ROM, RAM, EEPROM, I/O and
one timer with one input capture and two output
compare systems.
