The Atmel SAM4L 32-bit microcontroller family is based on a Cortex-M4 and features ultra-low power consumption and fast wake-up time. They take as little as 90 µA/MHz in active mode and have achieved a 28 CoreMark/mA rating using IAR Embedded Workbench, version 6.40.
The devices take only 1.5 µA in sleep mode, with full RAM retention, and 700 nA in back-up mode. They have wake-up times down to 1.5 µs from even the deepest sleep modes and also feature a peripheral event system that allows peripherals to communicate directly with one another without using the CPU and SleepWalking technology that allows a peripheral to qualify incoming data without the use of the CPU, eliminating unneeded wake-ups. The ICs come in 48-, 64- and 100-pin QFP or QFN packages. ($3.90 to $4.12 ea/1,000 — samples available now, production November.)
