STMicroelectronics has been responding to the automotive challenge for many years. Today, our solutions are not onlycost-effective but they offer real innovation, covering every application found in modern cars. The ST72561 is a family ofcar networking devices addressing CAN- and LIN-bus applications. All devices in this family are based on a commonindustry-standard 8-bit core, featuring an enhanced instruction set and are available with FLASH or ROM programmemory. This family of products is targeting car body electronics, as well as power train, with a focus on low powerconsumption and a wide range of packages. Due to its comprehensive features and competitive price, the device is alsosuited to industrial and consumer applications requiring CAN or UART communication. It is the smallest availablemicrocontroller with 2 UART and 1 CAN-bus interface.
n LINSCI™ macrocell – specially enhanced to support the LIN protocol and featuring:
• Automatic LIN Header handling and filtering of irrelevant LIN frames, saving up to 90% of CPU load dedicated to the LIN communication
• Extended error detection and signaling, making error handling easy for the application, in particular time-out detection
n BeCAN cell – a very powerful CAN cell on the Bosch CAN core. ST has added a processor interface with two transmit mailboxes, a three message deep RX-FIFO and six filter banks (each two x 32-bit), which allow extremely efficient message filtering by ID-groups or even single IDs
