DescriptionThe ST72272 series is a HCMOS microcontroller unit (MCU) from the ST7 family with a dedicated D/A Converter peripherals offering 4 PWM outputs.
It is based around an industry standard 8-bit core and offers an enhanced instruction set. The processor runs with an external clock up to 24 MHz with a 5.5V supply. Due to the fully static design of this device, operation down to DC is possible. Under software control the ST72272 can be placed in WAIT, SLOW or HALT mode thus reducing power consumption. The enhanced instruction 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 on the whole memory.
The ST72272 includes an on-chip oscillator, CPU, 8 to 16 Kbytes ROM/OTP/EPROM, 384 to 512 bytes RAM, 18 I/O lines, a Timer with 2 Input Captures and 2 Output Compares, a 4-channel A/D Converter, an I2C multi Master, a Watchdog Reset and a 4-channel 10-bit D/A Converter with PWM output.
