ST7277

Description

TheST7277i s a HCMOS microcontroller unit (MCU) from the ST7 family with dedicated peripherals for Monitor applications. It is based around an industry standard 8-bit core and offers an enhanced instruction set.The processor runs with an extern alclock at 24MHz with a 5V supply. Due to the fully static design o fthis device, operation down to DC is possible.Under
 software control the ST7277 can be placed in WAIT or HALT modet hus reducing power consumption. The enhanced instruction set and addressing modes afford real programming potential.

Inaddition to standard 8-bit data management the ST7277 features true bit manipulation, 8x8 unsigned multiplicationa nd indirect addressing modes.

The ST7277 includes anon-chiposcillator,CPU,Sync Processor for video timing & Vfback analysis, up to 60K ROM,up to 2K RAM, USB/DMA, I/O, a timer with 2 inputcaptures and 2 output com-
pares, an 8-channel Analog to Digital Converter,DDC/DMA,I²C multi Master, SCIS erial Communi cations Interface,Watch dogReset,an Infra Red Control preprocessor,and one1 2-bit and eight 10-bit PWM/BRM outputs for analog DC control ofexternal functions.
