The ST72104G, ST72215G, ST72216G and ST72254G devices are members of the ST7 microcontroller family. They can be grouped as follows:
• ST72254G devices are designed for mid-range applications with ADC and I²C interface capabilities.
• ST72215/6G devices target the same range of applications but without I²C interface.
• ST72104G devices are for applications that do not need ADC and I²C peripherals.
All devices are based on a common industrystandard 8-bit core, featuring an enhanced instruction set.
The ST72C104G, ST72C215G, ST72C216G and ST72C254G versions feature single-voltage FLASH memory with byte-by-byte In-Situ Programming (ISP) capability.
