8-bit Microcontrollers for Automotive

STMicroelectronics offers a complete family of automotive microcontrollers based on a common industry-standard 8-bit core, including ST7 and ST9 microcontrollers' families.

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 the ST7 devices feature an enhanced instruction set and are available with FLASH or ROM program memory.

The ST9 microcontroller series is a high-performance MCU family which offers fast program execution, efficient use of memory, fast data handling and context switching, input/output flexibility, with easy system expansion.

Related Information

LIN (Local Interconnect Network) is an automotive sub-bus system based on a serial communications protocol. ST's Automotive microcontrollers support the LIN protocol. Automotive Microcontrollers 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 1Mbps 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.
