ATA5831 - UHF ASK/FSK Transceiver

General Description

The Atmel® ATA5831/2/3 is a highly integrated, low-power UHF ASK/FSK RF transceiver with an integrated AVR® microcontroller.

It is package and pin-to-pin compatible with the previous generation of RF devices (Atmel ATA5830N and Atmel ATA5780N).

Key Features

  • AVR® microcontroller core with 1Kbyte SRAM and 24Kbyte RF library in firmware (ROM).
  • Atmel® ATA5831: 20Kbyte of user flash.
  • Atmel ATA5832: 20Kbyte of user ROM.
  • Atmel ATA5833: No user memory.
  • RF library in firmware only.
  • Supported frequency ranges.
  • Low-band 310MHz to 318MHz, 418MHz to 477MHz.
  • High-band 836MHz to 956MHz.
  • 315.00MHz/433.92MHz/868.30MHz and 915.00MHz with one 24.305MHz crystal.
  • Low current consumption.
  • 9.8mA for RXMo.
