General Product Description

Overview

The ATA5830 is a highly integrated, low power UHF ASK/FSK RF-transceiver. The Atmel ATA5830 is partitioned into several sections an RF frontend, a digital baseband, and a low power 8 bit AVR microcontroller. The product is designed for the ISM frequency bands in the ranges of 310 to 318MHz, 418 to 477MHz and 836 to 928MHz. 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. The transmit path uses a closed loop fractional-N modulator with gaussian shaping and preemphasis functionality for high data rates. In addition, the highly flexible and configurable baseband signal processing allows the transceiver to operate in several scanning, wake-up and automatic self polling scenarios. For example, during polling the IC can seek certain message content IDs and save valid telegram data in the FIFO buffer for later retrieval. The device possess two receive paths that enable parallel search for two telegrams with different modulations, data rates, wake-up conditions, etc. The highly configurable and autonomous scanning capability enables polling of up to five application channels such as 3-channel RKE, TPMS, PEG. The configuration of the transceiver is stored in a 512 byte EEPROM. The SPI allows for external control and reconfiguration of the device. The internal microcontroller and 6 KB Flash can be used to add customer extensions to the Atmel firmware. The debug wire and ISP interface are available for programming purposes.

Target Applications

The transceiver is designed to be used in the following application areas:
• Remote Keyless Entry System RKE
• Passive Entry Go System PEG
• Tire Pressure Monitoring System TPM,TPMS
• Remote Start System RS
• Remote Control System, e.g. garage door open
• Smart RF applications
• Telemetering Systems Three applications with a total of 5 channels are supported by the Atmel firmware for autonomous self polling.

Main Extended Features of the Atmel ATA5830

RF Performance The ATA5830 provides high sensitivity and programmable transmit power up to 14dBm. The high image rejection and outstanding blocking performance enable a robust application against interferer with a low cost design. In addition, the programmable channel filter bandwidth provides flexibility to adapt to various system requirements.

Automatic Self Polling and Multi Channel Capability The autonomous self polling supports the automatic scanning for three different applications such as Remote Keyless Entry RKE , Tire Pressure Monitoring System TPMS and Remote Start RS using one IC. Additionally multi channel systems with up to three frequencies can be scanned. This means five frequencies can be scanned in the autonomous polling scheme three for RKE, one for TPMS and one for RS. The configuration of each application is independent of the others. This is possible because of the flexibility in the digital baseband and two different baseband receiving paths. The IC can immediately scan all applications upon power-up without the need for any initial configuration by an external microcontroller.

Wake-up Scenario and ID Scanning The powerful baseband signal processing is designed to offload these time consuming tasks from the host controller. This allows the transceiver to discard unwanted telegrams and limit external microcontroller wake up to valid telegrams only. Up to 7 criteria can be used to determine the telegram validity from carrier check on the lowest level to start of frame ID pattern match at the highest level.

Two Parallel Receiving Paths The transceiver’s baseband contains two data paths. The parameters of both paths can be set differently, e.g. the modulation type or data rate. Generally both paths are working simultaneously but only the first path detecting a valid telegram will be used for further data reception and filling of the 32 byte buffer. The 32 byte receive data buffer can be accessed using SPI commands from the external host microcontroller.

Channel Statistic In order to accelerate the communication in multi channel applications the Atmel ATA5830 offers a feature defined as channel statistic. If this feature is selected, the IC will find the best channel within the three RKE channels with regard to interference and automatically select the best channel for the first transmission.

Antenna Tuning and SPDT For applications using a loop antenna, the Atmel ATA5830 offers an automatic antenna tuning feature which improves the antenna performance by compensating for “hand effects” or matching component value variations. The integrated SPDT acts as RX/TX switch which eliminates the cost of an external RX/TX switch.

Customer Application Software All the functionality is implemented in 24KB of ROM firmware and controlled by SPI commands. In addition, 6KB of Flash is available to enable customer specific software functionality. Examples for flash customization are a extension of SPI commands, b usage of a single wire interface instead of SPI, c polling adaptations, d protocol handling, etc. To achieve customer specific functionality, parts of the ROM code can be replaced with Flash code.

EEPROM Configuration

The configuration of the device e.g. RF-frequency, modulation type, data rate, etc. is stored in 512KB of EEPROM that is integrated within the ATA5830. This improves the efficiency of the SPI control since most of the configuration comes from the EEPROM. In most applications, only the received or transmitted data and short SPI commands are required. The device is delivered with a standard configuration only deviations from that need to be configured. Device configuration uses only a part of the 512KB of EEPROM leaving free space available for additional customer data storage.
