Texas Instruments Inc. rolls out the CC2533, the successor to the CC2530 SoC released in May 2009, as an optimised IEEE 802.15.4 SoC designed for the ZigBee RF4CE specification for radio-frequency communications.

An "out-of-the-box" solution for home entertainment devices such as TVs, set top boxes, Blu-Ray players, and home theaters, it promises lower power consumption, higher reliability and lower bill-of-materials (BOM) cost than competing devices. The free RemoTI protocol stack with reference designs and sample applications is available to designers to allow them to quickly implement remote controls and target controllers.

The CC2533 is available in 64KB and 96KB in-system programmable flash versions and also provides a pin-compatible upgrade path to CC2531 with 256KB of flash and USB interface.

Other key features are: four power modes, including a 1�A sleep mode, which means 10 times longer battery life compared to IR-based remote controls; a best-in-class transceiver with a typical receiver sensitivity of -97dBm and output power of 7dBm; and 5-channel DMA, 23 GPIOs, two USARTs, SPI, I2C and four timers.

The ZigBee RF4CE specification, announced in March 2009, allows for faster, more reliable and greater flexibility for devices operating across larger distances.

Pricing for the CC2533, which is available in a QFN-40 package, starts at Rs.92.93 ($1.99) per 10,000 units.
