TI Introduces 2.4 GHz Rf Transceiver For Zigbee®/IEEE 802.15.4 And Proprietary Low-Power Wireless Applications


DALLAS - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the company’s second-generation ZigBee®/IEEE 802.15.4 radio-frequency (RF) transceiver designed for the 2.4 GHz unlicensed ISM (industrial, scientific, medical) frequency band. Featuring state-of-the-art selectivity/co-existence and excellent link budget, the CC2520 targets a wide variety of ZigBee/IEEE 802.15.4 and proprietary wireless systems used in industrial monitoring and control, home and building automation, set-top boxes, remote controls and wireless sensor networks.

CC2520 – 2.4 GHz RF Transceiver

In a typical system, the CC2520 will be used together with a microcontroller, such as TI’s MSP430 ultra-low power MCUs, and a few additional passive components. The CC2520 reduces the load on the host controller by providing extensive hardware support for packet handling, data buffering, burst transmissions, data encryption, data authentication, clear channel assessment, link quality indication and packet timing information. The MSP430 MCU series is an excellent option for ZigBee-based applications due to its highly integrated peripherals like dynamic memory access (DMA) and digital-to-analog (DAC) and analog-to-digital converters (ADC) that provide high performance yet consume very little power.

Key CC2520 specifications include 1.8 V to 3.8 V supply range, -40C to +125C temperature range, 103 dB link budget (400 m line-of-sight range with the development kit), 50 dB adjacent channel rejection. The CC2520 provides an easy upgrade path for the CC2420 RF transceiver.

Availability and Packaging

The CC2520 is available now from TI and its authorized distributors in 5 mm x 5 mm QFN-28 package. Suggested resale pricing for the CC2520 starts at $3.10 each in 100-unit quantities. Start your development today with a comprehensive development kit (CC2520DK) that includes both hardware and software for advanced prototyping.

ZigBee-2007: ZigBee and ZigBee PRO

With the latest announcement by the ZigBee Alliance, ZigBee-2007 is now official with both its ZigBee and ZigBee PRO stack profiles fully ratified and tested. TI achieved Golden Unit status with continued enhancements to its ZigBee solution and will have availability of ZigBee PRO in 2Q 2008. TI’s Z-Stack 2.0.0 release (supporting both stack profiles of ZigBee-2007) will also be available in 2Q 2008.
