ATA5773C - UHF ASK/FSK Transmitter

Download the ATA5773C datasheet PDF. This datasheet also covers the ATA5771C variant, as both devices belong to the same uhf ask/fsk transmitter family and are provided as variant models within a single manufacturer datasheet.

General Description

The Atmel® ATA5771C/73C/74C is a highly flexible programmable transmitter containing the Atmel AVR® microcontroller Atmel ATtiny44V and the UHF PLL transmitters in a small QFN24 5mm × 5mm package.

Key Features

  • Atmel® AVR® microcontroller and RF transmitter PLL in a single QFN24 5mm × 5mm package (pitch 0.65mm).
  • Operating frequency ranges 310MHz to 350MHz, 429MHz to 439MHz and 868MHz to 928MHz.
  • Temperature range.
  • 40°C to +85°C.
  • Supply voltage 2.0V to 3.6V allowing usage of single Li-cell power supply.
  • Low power consumption.
  • Active mode: typical 9.8mA at 3.0V and 4MHz microcontroller-clock.
  • Power-down mode: Typical 200nA at 3.0V.
  • Modulation scheme ASK/FSK.
