Note: Stresses above those listed as "absolute maximum ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these conditions is not implied. Exposure to maximum
rating conditions for extended periods may affect device reliability.

The ST72371/ST72372 HCMOS Microcontroller Units are members of the ST7 family. These devices are based on an industry standard 8-bit core and feature an enhanced instruction set. The processor runs with an external clock up to 24 MHz with a 5.5V supply. Under software control the ST72371/ST72372 can be placed in WAIT, SLOW or HALT modes 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 ST72371 include an on-chip oscillator, CPU, 16K bytes program memory, 512 bytes RAM, 23 to 32 I/O lines, a Timer with 2 Input Captures and 2 Output Compares (with 1 output pin), a 4 to 8 channel A/D Converter, an I²C multi Master, an SCI⁽¹⁾ Serial Communications Interface, a Watchdog Reset, four 10-bit and one 12-bit D/A Converter channels with PWM output.
