Atmel Corporation has introduced four AEC Q100-qualified AVR flash microcontrollers for automotive power train, body, chassis, safety and security applications involving sensor and/or actuator control, and CAN and LIN networks.
The ATmega48, ATmega88, ATmega168, and the AT90CAN128 are manufactured according to ISO-TS-16949 and available in three automotive temperature ranges (-40 °C to 85 °C, -40 °C to 105 °C and -40 °C to 125 °C). The ATmega48/88/168 support 4 kB, 8 kB and 16 kB of flash memory respectively. The single-chip AT90CAN128 integrates a V2.0A/V2.0B CAN controller and a 128 kB flash program memory.
By executing instructions in a single clock cycle, the AVR microcontrollers achieve throughput approaching one MIP per MHz, allowing system designers to optimize power consumption vs. processing speed, while meeting EMI requirements. With a 16 MIPS AVR RISC engine and an efficient on-chip hardware multiplier, the AVR devices execute computing tasks that would usually require a more expensive microcontroller, and do so even at low operating voltages (2.7 V to 5.5 V).
“By the end of 2006, the 8-pin ATtiny25/45/85, ranging from 2 kB to 8 kB flash memory and the AT90CAN32/64 (CAN 32 kB/64 kB flash) will be the next products to be fully automotive qualified," said Philippe Malecha, Atmel’s automotive business development director. "The automotive AVR portfolio will expand rapidly, ranging from 2 kB to 128 kB flash program memory, in low- and high-pin count packages.” He said Atmel automotive AVR devices will cover the needs of specific automotive applications such as dcmotor control. The ATmega48/88/168 are available in 32-pin TQFP and QFN packages, while the AT90CAN128 is available in 64-pin TQFP and QFN packages.
