Texas Instruments has played a critical role in the development of the ZigBee RF4CE standard and TI’s portfolio of low-power RF hardware and software will drive even stronger penetration of RF4CE in next-generation consumer electronics,” said Bas Driesen, chairman of the RF4CE Steering Committee. “As consumers continue to demand new capabilities and innovation, ZigBee RF4CE delivers the enabling technology to give users a unique and improved living room experience.”
ZigBee RF4CE, first announced in March 2009, is a standardized specification for radio-frequency communications that enables faster, more reliable and greater flexibility for devices to operate from larger distances. It removes the line-of-sight and field-of-vision barriers in today’s IR (infrared) remotes. With its two-way communication, ZigBee RF4CE opens the door to a whole new set of capabilities and consumer experiences.
CC2533: Key features and benefits
· On-chip memory: Offers options of 64-KB and 96-KB in-system programmable Flash optimized for ZigBee RF4CE applications; provides pin-compatible upgrade path to CC2531 with 256 KB of Flash and USB interface.
· Low power: Four flexible power modes offer lowest current consumption, including a 1-uA sleep mode, allowing up to 10 times longer battery life compared to IR-based remote controls.
· Best performance: Device integrates a best-in-class transceiver with a typical receiver sensitivity of
-97 dBm and output power of 7 dBm.
· Rich peripheral set: 5-channel DMA, 23 GPIOs, 2 USARTs, SPI, I2C and 4 timers allows for additional system integration with user interface, reducing overall system BOM.
· Free stack: TI offers a free, downloadable software stack, RemoTI network protocol, reference designs and tools to ensure customers have everything needed for system development.
