Atmel Corp. announced an 8bit RISC Flash microcontroller, said to be the first to be qualified for operation up to 150C (AECQ100 Grade 0).

Already available in -40C to 125C operating temperature range, the ATmega88 AVR microcontroller is now capable of withstanding automotive temperature extremes, allowing designers to distribute intelligence and control functions directly into gearboxes, engine sensors and actuators, transfer cases, turbochargers, and finally simplifying the wiring network.

Compared with the existing 8bit ROM competition, Atmel said its robust non-volatile memory technology offers an unmatched capability to designers. The EEPROM is suitable for storing data, and the self-programmable Flash allows for the code updating within an application even after system deployment. Using Atmel's Flash technology eliminates the expensive and time-consuming steps inherent in mask ROM-based microcontrollers.

The ATmega88 device integrates a high number of features, Atmel said, thus significantly reducing complete system chip count. This includes an embedded 8Kbyte Flash program memory and 512byte EEPROM, a variable gain amplifier, a 10bit ADC, a fast analog comparator, and an on-chip calibrated 8MHz RC oscillator, avoiding the need for an external crystal. Other on-chip features such as a Power-on-Reset, a Brown-out-Detector and a watchdog with dedicated oscillator also contribute to the overall system reliability.

The ATmega88 150C-compliant samples are available now in 32-pin QFN package. Production will start Q1 2007.

The AVR full suite of low-cost development tools supports the automotive AVR microcontrollers for a fast, simple and successful development process.

By the end of 2006, the 8-pin ATtiny45 with 4-Kbyte Flash memory will be sampled in -40C to 150C temperature range.

Atmel will showcase its AVR family of flash-based and ARM-based MCU families at the 6th Annual ESC-Taiwan" target=_blank>Embedded Systems Conference-Taiwan on August 17-18 at the Taipei International Convention Center.
