Introduction
The Atmel® ATA8210/15 is a highly integrated, low-power UHF ASK/FSK RF receiver with an integrated AVR®
microcontroller.
The Atmel ATA8210/15 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, 418MHz to
477MHz and 836MHz to 956MHz. The external part count is kept to a minimum due to the very high level of integration in
this device. By combining outstanding RF performance with highly sophisticated baseband signal processing, robust
wireless communication can be easily achieved. The receive path uses a low-IF architecture with an integrated double
quadrature receiver and digitized IF processing. This results in high image rejection and excellent blocking performance. In
addition, highly flexible and configurable baseband signal processing allows the receiver to operate in several scanning,
wake-up and automatic self-polling scenarios. For example, during polling the IC can scan for specific message content
(IDs) and save valid telegram data in the FIFO buffer for later retrieval. The device integrates two receive paths that enable
a parallel search for two telegrams with different modulations, data rates, wake-up conditions, etc.
The Atmel ATA8210/15 implements a flexible service configuration concept and supports up to 15 channels. The channels
are grouped into five service configurations with three channels each. Three service configurations are located in the
EEPROM. Two service configurations are located in the SRAM to allow on-the-fly modifications during IDLEMode via SPI
commands or application software. The application software is located in the Flash for Atmel ATA8210. Highly configurable
and autonomous scanning capability enables flexible polling scenarios with up to 15 channels. The configuration of the
receiver is stored in a 1024byte EEPROM. The SPI interface enables external control and device reconfiguration.

In the Atmel ATA8210 the internal microcontroller with 20Kbyte user Flash can be used to add custom extensions to the
Atmel firmware. The Atmel ATA8215 embeds only the firmware ROM without user memory.
The debugWIRE and ISP interface are available for programming purposes.
Compatibility to the Atmel ATA8510/15
The Atmel ATA8210/15 is pin-to-pin compatible with the Atmel ATA8510/15 transceivers. The Rx performance of the
receivers matches that of the transceivers.
