Description
1.1 Introduction
The Atmel® ATA5781/2/3 is a highly integrated, low-power UHF ASK/FSK RF receiver with an integrated AVR® microcontroller.It is package and pin-to-pin compatible with the previous generation of RF devices (Atmel ATA5830N, ATA5831/2/3 and Atmel ATA5780N).The Atmel ATA5781/2/3 is partitioned into three sections; an RF front end, a digital baseband and the low-power 8-bit AVR microcontroller.The product is designed for the ISM frequency bands in the ranges of 310MHz to 318MHz, 4
