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.
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.
In addition to standard 8-bit data management the
ST7 features true bit manipulation, 8x8 unsigned
multiplication and indirect addressing modes.
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.
