汽车级 ST72254G2 8位MCU用于汽车的单电压Flash/ ROM内存,ADC,16位定时器及SPI,I2C总线接口SO28封装
ST72216G-Auto and ST72254G-Auto devices are members of the ST7 microcontroller family. They can be grouped as follows:
– ST72254G-Auto devices are designed for midrange applications with ADC and I2C interface capabilities.
– ST72215/6G-Auto devices target the same range of applications but without I2C interface.
– ST72104G-Auto 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.
Under software control, all devices can be placed in WAIT, SLOW, 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.
For easy reference, all parametric data are located in Section 13 on page 95.
