System-on-Chip Solution for IEEE 802.15.4 and ZigBee Applications - CC2531

CC2531 (ACTIVE)

System-on-Chip Solution for IEEE 802.15.4 and ZigBee Applications

Description

The CC2531 is a USB enabled true system-on-chip (SoC) solution for IEEE 802.15.4, ZigBee and RF4CE applications. It enables USB dongles or USB upgradable network nodes to be built with low total bill-of-material costs. The CC2531 combines the performance of a leading RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable flash memory, 8-KB RAM, and many other powerful features. The CC2531 has various operating modes, making it suited for systems where ultralow power consumption is required. Short transition times between operating modes further ensure low energy consumption. Source code for USB HID and CDC libraries and examples are downloadable from the CC2531 product page on www.ti.com.

Combined with the industry-leading and golden-unit-status ZigBee protocol stack (Z-Stack) from Texas Instruments, the CC2531 provides a robust and complete ZigBee USB dongle or firmware upgradable network node.

Combined with the golden-unit-status RemoTI stack from Texas Instruments, the CC2531 provides a robust ZigBee RF4CE remote-control target for USB dongle or TV/STB implementations.
