Embedded ultra low power AVR 8-bit micro-controller IC that integrates RF transmission and LF receiving functionality for wake-up purposes in a small QFN32 package.RF transmission is based on Atmel IP for 432-MHz to 448-MHz frequency ranges with a typical output power of up to 6dBm. Transmission is suited for ASK and FSK modulation with up to a 20-kbaud data rate in manchester mode.Its integrated programmable 125-kHz LF-receiver channel has an extremely low current consumption in active listening mode and is especially suited for wake-up purposes.
