Atmel Corp. has announced two new low power 32-pin tinyAVR MCUs, the ATtiny48 and ATtiny88 devices, which have 4- and 8Kbytes of flash memory, respectively. These AVR MCUs consume less than 240?A at 1.8V and 1MHz, and below 100nA in power-down mode and are suited for portable and power-sensitive systems such as remote control, accessories and small appliances.

The tinyAVR MCUs utilize Atmel's picoPower technology that eliminates unnecessary power consumption. They have a zero power brown-out detection circuitry that can be turned off during sleep modes, a power reduction register that powers down individual peripherals, and digital input disable registers that remove leakage current on ADC input pins.

The ATtiny48/88 operates from 1.8V to 5.5V and features a 10bit ADC, SPI, ?C interface, internal temperature sensor, and have up to 12Mips throughput at 12MHz. Like all the other AVR MCUs, the ATtiny48/88 features an on-chip debug system for easy, fast and robust development.

"Atmel's picoPower megaAVR devices offer the best-in-class power saving features and performance. The ATtiny48/88 is now extending the reach, offering an affordable solution for applications that require very low power consumption and are very cost sensitive. Our customers in the consumer electronics market want to develop products that consume less and less power, and the new ATtiny48/88 are a perfect fit," said Jukka Eskelinen, director of tinyAVR product marketing.

All tinyAVR MCUs use the standard AVR MCU development tools. The AVR Studio AVR IDE is available free of charge on Atmel's Web site.

Samples for the ATtiny48 are available now, the ATtiny88 will be available in Q3 08 in QFN32, QFN28, TQFP32 and PDIP28 packages. Volume prices for 10,000 units are 80 cents for the ATtiny48 and $1.04 for the ATtiny88.
