ATA5771 Overview
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. These devices have been specially developed for the demands of RF low-cost data transmission systems with data rates of up to 32 kBit/s. Its main applications are in the areas of Remote Keyless-Entry...
