Atmel Offers Seamless 802.15.4/ZigBee Migration for AVR-based Embedded Sensor and Control Applications

    San Jose, California (ots/PRNewswire) -

    - 103 dB link budget cuts system cost by up to 2/3, low power offers 5+  year battery life. Fully compliant 802.15.4 MAC and daughter board for STK500  included in user kits.

    Atmel(R) Corporation (Nasdaq: ATML) announced today an 802.15.4/ZigBee(TM) solution that offers seamless migration to wireless  networking for the more than 30,000 AVR(R)-based designs in automotive,  industrial, and building control applications. The AVR Z-Link(TM) solution  includes Atmel's ultra low power, high sensitivity 2.4 GHz AT86RF230  802.15.4 radio, an ultra low power ATmega1281 or ATmega 2561 AVR  microcontroller, and a small footprint, fully compliant media access control  (MAC) software optimized for the AVR architecture. This chip combination  consumes less power, has a higher link budget, and a wider operating range than any 802.15.4 solution on the market today under comparable operating  conditions.

    Network and application layer software are provided by the Atmel's network of expert third-party vendors who offer optimized solutions in the IEEE(R) 802.15.4 standard and the ZigBee(TM) protocols.

    103 dB Link Budget Cuts System Costs -- The -100 dB receive sensitivity and 3 dB transmit power of Atmel's Z-Link radio give it the highest link budget of any 802.15.4 radio on the market today. The AT86RF230 has line-of-sight range up to 2.8 times that of competing radios, reducing the total number of nodes required in the network and cutting 802.15.4 system cost by as much as 60%. The 103 dB link budget of the radio is achieved without external power amplifiers, resulting in a low bill of materials (BOM) cost. Only six external components are required for the radio function, the industry's lowest component count.

    Lowest Power Radio/Controller Combo Extends End-node Battery Life -- 802.15.4/ZigBee end nodes are usually battery-powered, mandating multi-year battery life. With radio power consumption of 17 mA during transmission, 15 mA during receive mode, and 0.7 uA in sleep mode Atmel's Z-Link radio, with true 1.8V operation consumes the least power of any 802.15.4 radio on the market.

    In a real-life application with one transmission per minute, the Atmel chip set consumes significantly less than 0.01 mA hours on average, resulting in a battery life of greater than 5 years using two AA 2700 mA hours batteries. The battery life of an Atmel end-node is predicted to be limited by the other non-radio/MCU system components, such as sensors or actuators, or by the shelf life of the battery.

    AVR Microcontroller Offers Flexibility -- This solution is supported by Atmel's AVR family of 8-bit RISC microcontrollers with flash memory densities ranging from 32 KB to 256 KB. Existing AVR applications can be converted to 802.15.4 functionality by porting the legacy code to an AVR with a larger flash memory to accommodate the MAC and security layers.

    RZ502 Accessory Kit -- Atmel's Z-Link radio is available as an add-on to STK(R)500/501 AVR starter kits. This RZ502 accessory kit allows existing STK500 users to easily upgrade to a wireless connection option.

    RZ200 Demonstration Kit -- The demonstration kit contains five radio controller boards with Atmel's Z-Link 2.4 GHz 802.15.4 radio and ATmega1281 microcontroller, plus AVR ISP programming dongle, all the necessary cables, batteries, and antennas to allow users to create a simple five-node network for application evaluation.
