Description

The ST7275-1 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 ST7275 can be placed in WAIT or HALT mode thus reducing power consumption. The enhanced instruction of the ST7275-1 set and addressing modes afford real programming potential.

In addition to standard 8-bit data management the ST7 features true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes.

The ST7275-1 includes an on-chip oscillator, CPU, Sync Processor for video timing & Vfback analysis, up to 60K ROM, up to 2K RAM, I/O, a timer with 2 input captures and 2 output compares, an 8-channel Analog to Digital Converter, DDC/DMA, I2C multi Master, SCI Serial Communications Interface, Watchdog Reset, an Infra Red Control preprocessor, and one 12-bit and eight 10-bit PWM/BRM outputs for analog DC control of external functions.
