ATA5835 - Microchip

ATA5835 UHF ASK/FSK Transceiver

ATA5835 UHF ASK/FSK Transceiver Summary Data Sheet Introduction The ATA5835 is an ultra-low power, Ultra High Frequency (UHF) smart transceiver, based on an 8-bit AVR® microcontroller with System on Chip (SoC). It consists of an RF front end, a complex digital baseband, and a low-power 8-bit AVR microcontroller. This leads to a minimal Bill of Material (BOM.
