ATA5773 - Microcontroller

Download the ATA5773 datasheet PDF. This datasheet also covers the ATA5771 variant, as both devices belong to the same microcontroller family and are provided as variant models within a single manufacturer datasheet.

General Description

The ATA5771/ATA5773/ATA5774 is a single key fob IC containing the AVR microcontroller ATtiny44V and the UHF PLL transmitters T5750/53/54 build-up using a stacked die technique supplied in a QFN24 5 mm × 5 mm package.

Key Features

  • Complete Key Fob IC Consisting of an AVR® Microcontroller and RF Transmitter PLL in a Single QFN24 5 mm × 5 mm Package (Pitch 0.65 mm).
  • f0 = 310 MHz to 350 MHz (ATA5773).
  • f0 = 429 MHz to 439 MHz (ATA5774).
  • f0 = 868 MHz to 928 MHz (ATA5771) Automotive Qualified Temperature Range.
