The ST7272 is an HCMOS Microcontroller Unit (MCU) from the ST7 family based on an industry-standard 8-bit core. It operates with a supply voltage range of 4.5V to 5.5V and supports oscillator frequencies up to 8MHz, while also allowing fully static operation down to DC.
The device integrates extensive on-chip peripherals including a digital Watchdog Timer, a 16-bit multipurpose timer with input captures and output compares, an upgraded Sync Processor for video blanking generation, and a DDC interface. It features 27 multifunctional bidirectional I/O lines, some with 12V open-drain drive capability.
