Atmel has announced the availability of a 128 KB picoPower megaAVR microcontroller targeting size-constrained, low-power applications.
The small 44-pin package makes the ATmega1284P suitable for applications such as wireless and Ethernet nodes, home automation and other code-intensive battery or signal-line powered products.
The device is pin- and feature-compatible to the ATmega164PA, ATmega324PA, and ATmega644PA. The four devices provide a drop-in migration path from 16 to 128 KB of Flash and 1 to 16 KB of RAM. The ATmega1284P consumes 100 nA in power-down mode, 700 nA in power-save mode and 0,45 mA in active mode at 1,8 V and 1 MHz.
The ATmega1284P is designed for applications that require extremely low power consumption. These applications can range from ZigBee self-powered light switches, to ZigBee Smart Energy-compliant water and gas meters that are being deployed worldwide and demand several years of maintenance-free operation on a single battery.
