1 GENERAL DESCRIPTION

1.1 INTRODUCTION

The ST72753 is a HCMOS microcontroller unit

(MCU) from the ST7 family with dedicated periph-

erals for Monitor applications.

In addition to standard 8-bit data management the

ST7 features true bit manipulation, 8x8 unsigned

multiplication and indirect addressing modes.

It is based around an industry standard 8-bit core

and offers an enhanced instruction set. The proc-

essor runs with an external clock at 24 MHz with

a 5V supply. Due to the fully static design of this

device, operation down to DC is possible. Under

software control the ST72753 can be placed in

WAIT or HALT mode thus reducing power con-

sumption. The enhanced instruction set and ad-

dressing modes afford real programming potential.

The device includes an on-chip oscillator, CPU,

Sync Processor for video timing & Vfback analy-

sis, up to 32K ROM, up to 1K RAM, I/O, a timer

with 2 input captures and 2 output compares, a 4-

channel Analog to Digital Converter, DDC/DMA,

I C multi Master, Watchdog Reset, and six 10-bit

PWM/BRM outputs for analog DC control of exter-

nal functions.
