Product Summary

The CC2531F256RHAR is a USB Enabled System-On-Chip Solution. The CC2531F256RHAR 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 CC2531F256RHAR 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 CC2531F256RHAR 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 CC2531F256RHAR product page on www.ti.com.
