General Product Description

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.

Atmel ATA8215

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.

Figure 1-1

shows an overview of the main functional blocks of the Atmel

ATA8210/15. External control of the

Atmel ATA8210/15 is performed through the SPI pins SCK, MOSI, MISO, and NSS on port B. The configuration of the

Atmel ATA8210/15 is stored in the EEPROM and a large portion of the functionality is defined by the firmware located in the

ROM and processed by the AVR

. An SPI command can trigger the AVR to configure the hardware according to settings

that are stored in the EEPROM and start up a given system mode (e.g., RXMode, or PollingMode). Internal events such as

“Start of Telegram” or “FIFO empty” are signaled to an external microcontroller on pin 28 (PB6/EVENT).

During the start-up of a service, the relevant part of the EEPROM content is copied to the SRAM. This allows faster access

by the AVR during the subsequent processing steps and eliminates the need to write to the EEPROM during runtime

because parameters can be modified directly in the SRAM. As a consequence the user does not need to observe the

EEPROM read/write cycle limitations.

It is important to note that all PWRON and NPWRON pins (PC1..5, PB4, PB7) are active in OFFMode. This means that even

if the Atmel ATA8210/15 is in OFFMode and the DVCC voltage is switched off, the power management circuitry within the

Atmel ATA8210/15 biases these pins with VS.

AVR ports can be used as button inputs, external LNA supply voltage (RX_ACTIVE), LED drivers, EVENT pin, switching

control for additional SPDT switches, general purpose digital inputs, or wake-up inputs, etc. Some functionality of these ports

is already implemented in the firmware and can be activated by adequate EEPROM configurations. Other functionality is

available only through custom software residing in the 20Kbyte Flash program memory (Atmel ATA8210).
