1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST7294 HCMOS Microcontroller Unit is a
member of the ST7 family of Microcontrollers. The
device is based on an industry-standard 8-bit core
and features an enhanced instruction set. The
CPU may be driven by an external 4MHz clock
when the device is operated with a 5V supply, or
by a 2MHz clock when operated with a 3V supply.
Thanks to the fully static design, operation is possible
down to DC. Under software control, the
ST7294 may be placed in either WAIT or HALT
modes, thus reducing power consumption. The
enhanced instruction set and addressing modes
afford real programming potential. In addition to
standard 8-bit data management, the ST7294 features
true bit manipulation, 8x8 unsigned multiplication
and indirect addressing modes. The device
includes a CPU, ROM, RAM, EEPROM, I/O, an
on-chip oscillator and a timer with input capture
and dual output compare systems.
