Atmel Corp. debuts the AT86RF233, an RF transceiver that boasts 60 per cent lower power consumption than its closest competitors for battery-operated wireless applications.

The Atmel AT86RF233 transceiver is optimised for industrial and consumer products that comply with ZigBee/IEEE 802.15.4, IPv6 over low-power wireless personal area networks (6LoWPAN) and high data rate 2.4GHz industrial, scientific and medical (ISM) band applications.

The transceiver also improves the RF performance making it an ideal solution for products such as gas and water meters, monitoring and control systems, and energy-harvesting equipment, that call for years of battery life without maintenance, said Atmel.

The AT86RF233 provides transceiver current consumption of 14mA, receiver current consumption of 6mA and sleep current consumption of 0.02µA. For a complete solution, design engineers can use a low-power, high-performance Atmel AVR or an Atmel ARM processor-based microcontroller as a companion chip. Together, the AT86RF233 transceiver and an AVR XMEGA MCU can deliver a low-power, cost-optimised solution to meet the operational requirements of applications that spend most of their time in low-power sleep mode and need fast wake-up times and short, active cycles, noted Atmel.

As a highly integrated solution, the AT86RF233 requires minimal external components. Design engineers can, therefore, lower their bill of material (BOM) costs and also reduce system board space, said Atmel. With support for antenna diversity, the AT86RF233 enhances RF performance and link reliability. On-board Advanced Encryption Standard (AES) ensures secure wireless end-to-end communication.

Supported by kits, tools and communication stacks, the AT86RF233 transceiver can be integrated into any design with efficiency, stated Atmel. Designers who pair the transceiver with an AVR XMEGA MCU can further optimise their design environment with Atmel Studio 6, the newest integrated development environment. Supporting both AVR MCUs as well as Atmel ARM Cortex-M processor-based devices, Atmel Studio 6 comes with 1,000 project examples with source code that eliminate most of the low-level coding in a design.

The AT86RF233 transceiver is available with the REB233SMAD-EK evaluation kit, which includes two AT86RF233 radio evaluation boards paired with the AVR XMEGA ATxmega256A3 MCU. Atmel also provides, free of charge, a variety of network software and programming examples, including the BitCloud ZigBee PRO and the BitCloud Public Profile Suite.
