ST72321AR6   8-BIT MCU WITH NESTED INTERRUPTS, FLASH,10-BIT ADC, FIVE TIMERS, SPI, SCI, I2C INTERFACE

Description

The ST72F321 and ST72321 devices are members of the ST7 microcontroller family designed for mid-range applications.

All devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set and are available with FLASH or ROM

program memory.

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
