汽车级 ST72141K2 8位微控制器的汽车与电动马达控制,ADC,16位定时器,SPI接口SO34封装
The ST72141K2-Auto devices are members of the ST7 microcontroller family designed specifically for motor control applications and including A/D conversion and SPI interface capabilities. They include an on-chip Motor Controller peripheral for control of electric brushless motors with or without sensors. An example application, for 6-step control of a Permanent Magnet DC motor, is shown in Figure 1.
The ST72141K2-Auto devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set.
Under software control, they 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.
