Atmel Corporation (Nasdaq: ATML) recently introduced the ATtiny167 family of AVR 8-bit microcontrollers for LIN Automotive networking applications. The ATtiny167 is optimized for LIN slave applications. It will be qualified to AECQ-100 grade 0 and sustain ambient temperatures of up to 150 degrees Celsius. Combined with a LIN transceiver (such as ATA662x or ATA666x) it brings a complete solution for sensors in a gearbox, exhaust gas system, pumps or turbo. Samples for the ATtiny167 are available now. Packages are available in a 20-pin SOIC, 20-Pin TSSOP, and 32-pin QFN. The ATtiny167 will be qualified at 125 degrees Celsius in all packages and 150 degrees Celsius in QFN and TSSOP packages. It will be available for volume production in December 2008. Prices start at $1.48 in 10,000 quantities for the 125 degrees qualified version.
The ATtiny167 includes a hardware LIN UART with automatic baud rate synchronization in slave mode. A frame processing request of only 2 interrupts, one for LIN identifier available and one for transmit or receive completed. Thanks to the collaboration with Mentor Graphics, a complete hardware and LIN software networking solution is available.
With integrated hardware routines, the code size for LIN is reduced to about 1 Kbyte of Flash leaving about 15 Kbytes of Flash to the user application. Automatic synchronization is performed on each entering frame without calling for any CPU resources and Interrupt generation is limited to the extreme minimum to not jeopardize the real time capability of the application.
