Product Summary
The ATA5773 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 x 5 mm package. The ATA5773 has 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 (RKE), Passive Entry Go (PEG), and Remote Start. The ATA5773 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.
