ST72264G2：8-bit MCU

The ST72260Gx, ST72262Gx and ST72264Gx devices are members of the ST7 microcontroller family. They can be grouped as follows :ST72264Gx devices are designed for mid-range applications with ADC, I²C and SCI interface capabilities.ST72262Gx devices target the same range of applications but without I²C interface or SCI. ST72260Gx devices are for applications that do not need ADC, I²C peripherals or SCI.

All devices are based on a common industrystandard 8-bit core, featuring an enhanced instruction set.

The ST72F260G, ST72F262G, and ST72F264G versions feature single-voltage FLASH memory with byte-by-byte In-Circuit Programming (ICP) capabilities.

Under software control, all devices can be placed in WAIT, SLOW, Active-HALT or HALT mode, reducing power consumption when the application is in idle or stand-by state.

The enhanced instruction set and addressing modes of the ST7 offer both power and flexibility to software developers, enabling the design of highly efficient and compact application code. In addition to standard 8-bit data management, all ST7 microcontrollers feature true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes.

For easy reference, all parametric data is located in Section 13 on page 126.
