The ST72T751N9B1 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 coreand offers an enhanced instruction set. The proc-essor runs with an external clock at 24 MHz   witha 5V supply. Due to the fully static design of thisdevice, operation down to DC is possible. Undersoftware control the ST72T751N9B1 can be placed inWAIT 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 theST7 features true bit manipulation, 8x8 unsignedmultiplication and indirect addressing modes.

The ST72T751N9B1 includes an on-chip oscillator, CPU,Sync Processor for video timing & Vfback analy-sis, up to 60K ROM, up to 2K RAM, I/O, a timerwith 2 input captures and 2 output compares, an 8-channel Analog to Digital Converter, DDC/DMA,I²C multi Master, SCI Serial Communications In-terface, Watchdog Reset, an Infra Red Controlpreprocessor, and one 12-bit and eight 10-bitPWM/BRM outputs for analog DC control of exter-nal functions.
