汽车级 ST72314N2 8位MCU单电压Flash/ ROM,ADC,16位定时器及SPI接口TQFP-64封装

The ST72334J/N-Auto, ST72314J/N-Auto and ST72124J-Auto devices are members of the ST7 microcontroller family. They can be grouped as follows:

• ST72334J/N-Auto devices are designed for midrange applications with Data EEPROM, ADC,SPI and SCI interface capabilities.
• ST72314J/N-Auto devices target the same range of applications but without Data EEPROM.
• ST72124J-Auto devices are for applications that do not need Data EEPROM and the ADC peripheral.

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

The ST72C334J/N-Auto, ST72C314J/N-Auto and ST72C124J-Auto versions feature single-voltage Flash memory with byte-by-byte In-Situ Programming (ISP) capability.

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 standby 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.
