1 GENERAL DESCRIPTION
1.1 INTRODUCTION The ST72752 is 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 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 ST72752 can be placed in WAIT or HALT mode thus reducing power consumption. The enhanced instruction set and addressing modes afford real programming potential. Figure 1. .ST72752 Block Diagram
PORT A
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 analysis, up to 32K ROM, up to 1K RAM, I/O, a timer with 2 input captures and 2 output pares, a 4channel Analog to Digital Converter, DDC/DMA, I2C multi Master, Watchdog...
