Atmel unveils 2.4GHz low-power RF transceiver for industrial applications

The transceiver offers 60 percent lower power consumption than current competitor devices while at the same time improving the RF performance. As a result it is a suitable solution for products such as gas and water meters, monitoring and control systems, and energy-harvesting equipment.

The AT86RF233 provides transceiver current consumption of 14mA, receiver current consumption of 6mA and sleep current consumption of 0.02uA. For a complete solution, design engineers can use a low-power, high-performance Atmel AVR or an Atmel ARM processor-based microcontroller (MCU) as a companion chip. Together, the AT86RF233 transceiver and an AVR XMEGA MCU can deliver a low-power solution that is able 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.

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

“With the 802.15.4-compliant market growing quickly towards half a billion units, we’re pleased to deliver a RF transceiver that meets a variety of industry standards while addressing our customers’ requirements for increasingly lower power consumption,” said Magnus Pedersen, product marketing director for microcontroller wireless solutions at Atmel. “The AT86RF233 transceiver will enable our customers to create feature-rich wireless products that provide the long battery life that their customers demand.”

Supported by kits, tools and communication stacks, the AT86RF233 transceiver can be integrated into any design. 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.
