ST72C215G2B6 [STMicroelectronics]

ST72C215G2B6 Description

The ST72C215G2B6 is an 8-BIT MCU with single voltage flash memory, ADC, 16-bit timers, SPI, I2C interfaces. Family members of the ST7 microcontroller are the ST72104G, ST72215G, ST72216G, and ST72254G devices. These are how they can be categorized:

- ST72254G devices have an I2C and ADC interface, making them suitable for mid-range applications.

- The ST72215/6G devices aim for a similar set of applications but do not have an I2C interface.

- Devices like the ST72104G are used in programs that don't require ADC and I2C peripherals.

A common 8-bit core that is industry standard and with an expanded instruction set serves as the foundation for all devices.

Single-voltage FLASH memory with byte-by-byte In-Situ Programming (ISP) functionality is available in the ST72C104G, ST72C215G, ST72C216G, and ST72C254G variants.

All devices can be put in WAIT, SLOW, or HALT mode under software control to save energy when an application is idle or in standby mode.

Software developers have power and flexibility because of the ST7's increased instruction set and addressing modes, which allow for the creation of incredibly efficient and small application code. All ST7 microcontrollers include actual bit manipulation, 8x8 unsigned multiplication, and indirect addressing modes in addition to ordinary 8-bit data management.
