Atmel(R) Corporation has announced the industries first 8-bit RISC Flash microcontroller to be qualified for operation up to +150 degrees Celsius (AECQ100 Grade 0).
Already available in -40 to +125 degrees Celsius operating temperature range, the ATmega88 AVR(R) microcontroller is now capable of withstanding automotive temperature extremes, thus 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 8-bit ROM competition, Atmel’s robust non- volatile memory technology offers an unmatched capability to designers. The EEPROM is ideal 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, thus significantly reducing complete system chip count. This includes an embedded 8-Kbyte Flash program memory and 512-byte EEPROM, a variable gain amplifier, a 10-bit analog-to-digital converter, a fast analog comparator, and an on-chip calibrated 8 MHz 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 150 degree-compliant samples are available now in 32-pin QFN package. Production will start in 1Q 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 -40 to +150 degrees Celsius temperature range.
