ST7汽车级微控制器
ST7 汽车级微控制器产品选型指南
STMicroelectronics offers a complete and well-established family of automotive microcontrollers based on the ST7 core, an industry-standard 8-bit architecture, extended by STMicroelectronics to improve support for high-level language programming and to provide additional interrupt handling features.
The ST7 microcontroller series has been designed for mid-range applications with or without CAN (controller area network) and/or LIN (local interconnect network) interfaces. All ST7 devices feature an enhanced instruction set and are available with Flash or ROM program memory.
The ST7 family includes a range of devices from 8 pins to 80 pins and from 1 Kbyte to 60 Kbytes, to fit your budget and needs

LIN (local interconnect network) is an automotive sub-bus system based on a serial communications protocol. ST's automotive microcontrollers support the LIN protocol.
CAN (controller area network) networks are now found in widely varying types of automotive systems. The standard CAN network is designed for speeds up to 1?Mbit/s in noisy environments. Its robustness is a result of powerful error management, multimaster architecture and the specification of the physical layer. It is now used extensively in European automotive markets, and is currently growing in the US automotive market.
