Single-Chip Wireless MCUs Address IEEE 802.15.4

Thu, 12/10/2009 - 2:32pm

wireless microcontrollers single chipAtmel announced a family of AVR wireless microcontroller (MCU) devices targeting wireless applications such as ZigBee and IPv6/6LoWPAN. The ATmega128RFA1 is IEEE 802.15.4 compliant and combines Atmel’s picoPower AVR MCU and a 2.4 GHz RF transceiver. The company’s picoPower technology offers ultra-low power consumption to ultimately enable longer battery life for wireless ZigBee applications, including smart energy, building automation, telecom and health care. ATmega128RFA1 is supported by Atmel’s QTouch Library, making it easy to combine capacitive touch functionality with RF in a single chip. The ATmega128RFA1 combines Atmel’s IEEE802.15.4 2.4 GHz transceiver with an AVR MCU on a single chip. These devices include a low-power, high performance AVR MCU with embedded flash memory. Other features include a long-range, high performance RF transceiver to ensure a reliable wireless link and a low current consumption for extended battery life. The MCUs in these devices run at a very low voltage operation without compromising performance. The wake-on-radio feature enables autonomous RF transmission and reception, further reducing power consumption keeping TRX RF active while the MCU is still in sleep mode.
