ST72774/ST727754/ST72734
1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST72774, ST72754 and ST72734 are
HCMOS microcontroller units (MCU) from the
ST727x4 family with dedicated peripherals for
Monitor applications.
They are based around an industry standard 8-bit
core and offer an enhanced instruction set. The
processor runs with an external clock at 12 or 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 ST727x4 can be placed
in WAIT mode thus reducing power consumption.
The HALT mode is no longer available.
The enhanced instruction set and addressing
modes afford real programming potential. Illegal
opcodes are patched and lead to a reset.

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,
System protection against illegal address jumps,
Sync Processor for video timing & Vfback analysis,
up to 60K Program Memory, up to 1K RAM, USB/
DMA, a Timing Measurement Unit, I/O, a timer with
2 input captures and 2 output compares, a 4-
channel Analog to Digital Converter, DDC, I
Single Master, Watchdog Reset, and eight 10-bit
PWM/BRM outputs for analog DC control of
external functions.
