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 ba.
● AVR® microcontroller core with 1Kbyte SRAM and 24Kbyte RF library in firmware
(ROM)
● Atmel® ATA5782: 20Kbyte of user flash
● Atmel ATA5783: 20Kbyte of user ROM
● Atmel ATA5781: No user memory — RF library in firmware only
● Supported frequency ranges
● Low-band 310MHz to 318MHz, 418MHz to 477MHz
● High-band 836MHz to 956MHz
● 315.00MHz/433.92MHz/868.30MHz and 915.00MHz with one 24.305MHz crystal
● Low current consumption
● 9.8mA for RXMode (low-band), 1.2mA for 21ms cycle three-channel polling
● Typical OFFMode current of 5nA (maximum 600nA at Vs = 3.6V and T = 85°C)
● Supports the.
