RF transceiver offers 60% lower power consumption than nearest competitor
Atmel's low power AT86RF233 rf transceiver is targeted at battery operated wireless applications such as utility meters, industrial monitoring and control systems and energy harvesting equipment.
Said to offer 60% lower power consumption than its nearest competitor, the device 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 band applications. It is designed to provide transceiver current consumption of 14mA, receiver current consumption of 6mA and sleep current consumption of 0.02uA.
"With the 802.15.4 compliant market growing quickly towards half a billion units, we're pleased to deliver an rf transceiver that meets a variety of industry standards while addressing our customers' requirements for increasingly lower power consumption," said Atmel's Magnus Pedersen. "The AT86RF233 transceiver will enable our customers to create feature rich wireless products that provide the long battery life that their customers demand."
For a complete solution, Atmel recommends designers use a low power Atmel AVR or an Atmel ARM processor based microcontroller in combination with the transceiver. This is said to deliver a low power, cost optimised solution that meets 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.
The AT86RF233 features Onboard Advanced Encryption Standard and requires minimal external components, resulting in reduced bom costs. With support for antenna diversity, it is optimised to enhance rf performance and link reliability.
