汽车级 ST7L19 8位MCU用于汽车的单电压闪存/ROM内存,数据EEPROM,ADC,5定时器的SPI SO20封装
The ST7L1x is a member of the ST7 microcontroller family suitable for automotive applications. All ST7 devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set.
The ST7L1 features Flash memory with byte-by-byte in-circuit programming (ICP) and inapplication programming (IAP) capability.
Under software control, the ST7L1 device 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.
