US-based Atmel released a new AVR 8-bit microcontroller aiming automotive LIN networking application.
The automotive body electronic subsystems are connected via LIN networks. They require tiny LIN controllers with analog/digital converters for sensor signal formatting and a versatile 16-bit timer. The ATtiny87 is the second device of a LIN which is optimised for LIN slave applications.
The ATtiny87 includes hardware LIN UART with automatic baud-rate synchronisation in slave mode. The frame processing requests only 2 interrupts; one for LIN identifier and one for transmit or receive completed. Vector developed the LIN driver for the Atmel ATtiny87 and ATtiny167 microcontroller family.
The ATtiny87 (8K Flash) is compatible with the ATtiny167 (16KB Flash) and is available in the same set of packages: QFN32, SO20 and TSSOP20. The ATtiny87 supports AECQ-100 grade0 and can sustain in temperature up to 150 degree Celsius. This new LIN driver supports communication packages which can be used by all Automotive OEMs. The LIN communication package supports all protocol versions in master or slave configurations including transport andor diagnostics layers.
