Atmel Corp. has released a new family of 32-pin picoPower AVR MCUs. The ATmega48P, 88P, 168P and 328P devices have 4, 8, 16 and 32Kbytes of flash memory, respectively.

The devices consume only 340?A in active mode at 1.8V running from the internal RC oscillator at 1MHz, 650nA in power-save mode with real time counter running and 100nA in power-down mode. The picoPower AVRs are pin-, performance- and code-compatible with existing AVR MCUs.

Atmel's picoPower technology will assist IC designers by eliminating unnecessary power consumption in sleep modes. These include an ultralow-power 32kHz crystal oscillator, automatic disabling and re-enabling of brown-out detection, (sleeping BOD) circuitry during sleep modes, a power reduction register (PRR) that completely powers down individual peripherals and digital input disable registers that removes leakage on ADC input pins. picoPower AVRs are well suited for low power applications and enables longer battery life for applications mostly in sleep modes.

The ATmega48P, 88P, 168P and 328P MCUs operate from 1.8-5.5V and feature a 10bit ADC, USART, SPI, two-wire interface, internal temperature sensor and have up to 20MIPS throughput at 20MHz. Similar to other AVR MCUs, the ATmega48P, 88P, 168P and 328P features an on-chip debug system for easy, fast and robust development.

The AVR picoPower MCUs use the standard AVR MCU development tools. The AVR Studio IDE is available free of charge on Atmel's Website.

Samples for the ATmega88P and ATmega168P are available now in QFN32 and TQFP32 packages. Samples for the ATmega48P will be available in August and the ATmega328P will be available in Q4, respectively.

Volume prices for 10,000 units are $1.18 for the ATmega48P, $1.65 for the ATmega88P, $2.00 for the ATmega168P and $2.65 for the ATmega328P, respectively.
