Microcontrollers feature several power-saving modes

19 September 2007 DSP, Micros & Memory

Atmel recently released a new family of 32-pin picoPower AVR microcontrollers. The ATmega48P/88P/168P/328P devices have 4, 8, 16 and 32 KB of Flash memory, respectively. These devices consume as little as 340 μA in active mode at 1,8 V running from the internal RC oscillator at 1 MHz, 650 nA in power-save mode with realtime counter running, and 100 nA in power-down mode. picoPower AVRs are pin-, performance- and code-compatible with existing AVR microcontrollers.

Atmel's picoPower technology is aimed at eliminating unnecessary power consumption in sleep modes. These include an ultra-low-power 32 kHz crystal oscillator, automatic disabling and re-enabling of brown-out detection, sleeping BOD circuitry during sleep modes, a power reduction register that completely powers down individual peripherals and digital input disable registers that remove leakage on ADC input pins.

These microcontrollers operate from 1,8 to 5,5 V and feature a 10-bit ADC, USART, SPI, 2-wire interface, internal temperature sensor, and have up to 20 MIPS throughput at 20 MHz. Similar to other AVR microcontrollers, these devices feature an on-chip debug system for easy, fast, and robust development.
