ATMEL’s picoPower technology reduces "power-save" power consumption to as little as 650nA, even with the 32kHz clock running and superior brown-out detection.
The two picoPower devices now available are the ATmega169P with a 4x25 segment LCD controller, and the ATmega165P general purpose microcontroller.
Available from Soanar , both microcontrollers have 16kB of Flash memory, 512 Bytes EEPROM and 1kB SRAM. They feature a 10-bit ADC, USART, SPI, two-wire-interface and operate from 1.8 to 5.5 volt with up to 16 MIPS throughput.
Fourteen additional 8-bit picoPower AVR microcontrollers will be added within the next twelve months. PicoPower microcontrollers consume down to 340uA in active mode, 150uA in idle mode at 1MHz, 650nA in power-save mode and 100nA in power-down mode. They will be pin, performance and code-compatible with existing AVR microcontrollers.
Atmel's picoPower technology utilises a variety of innovative techniques that eliminate unnecessary power consumption in power-down modes. These include an ultra low power 32kHz crystal oscillator, automatic disabling and re-enabling of brown out detection (BOD) circuitry during sleep modes, a power reduction register (PRR) that completely powers down individual peripherals, and digital input disable registers that turn off the digital inputs to specific pins.
The ATmega165P and the ATmega169P are available now in production quantities in 64-pin TQFP and 64-pin QFN packages.
