DescriptionThe ST72101, ST72213 and ST72212 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. They normally operate at a 16MHz oscillator frequency. Under software control, the ST72101, ST72213 and ST72212 may be placed in either 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 ST72101, ST72213 and ST72212 feature true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes on the whole memory. The devices include an on-chip oscillator, CPU, program memory (ROM/OTP/EPROM versions), RAM, 22 I/O lines and the following on-chip peripherals: Analog-to- Digital Converter (ADC) with 6 multiplexed analog inputs (ST72212 and ST72213 only), industry standard synchronous SPI serial interface, digital Watchdog, one or two independent 16-bit Timers, one featuring an External Clock Input, and both featuring Pulse Generator capabilities, 2 Input Captures and 2 Output Compares.
