Description
Atmel
ATA6285 and Atmel ATA6286 are embedded ultra low power AVR 8 bit micro-
controller ICs with integrated RF transmission and LF receiving functionality for
wake-up purposes in a small QFN32 package.
The RF transmission is based on well-known Atmel IPs for 313MHz to 317MHz (Atmel
ATA5756) and for 432MHz to 448MHz (Atmel ATA5757) frequency ranges with a typ-
ical output power up to 6dBm. They are suited for ASK and FSK modulation with up to
20kBaud data rate in manchester mode.
The integrated programmable 125kHz LF-Receiver channel has an extremely low cur-
rent consumption in active listening mode. Due to that, the LF-Receiver is especially
suited for wake-up purposes.
The programmable AVR 8-bit flash microcontroller include 8kBytes of In-System Self
Programmable Flash memory and 320Bytes EEPROM thus allowing the system inte-
grator to install field programmable firmware to meet system flexible requirements on
different platforms. Atmel ATA6285 and Atmel ATA6286 are configurable to meet
extremely low power requests in sleep mode, measurement mode and transmission
mode.
