1. General Description
The ATA5771/ATA5773/ATA5774 is a single key fob IC containing the AVR microcon-
troller 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 Key-
less-Entry (RKE), Passive Entry Go (PEG), and Remote Start. It can be used in the
frequency range of f0 = 310 MHz to 350 MHz, f0 = 429 MHz to 439 MHz or
f0 = 868 MHz to 928 MHz for ASK or FSK data transmission.
