Product Overview

The CC2531 USB is a USB enabled true system-on-chip (SoC) solution for IEEE 802.15.4, cc2531 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.

This blog will introduce CC2531 systematically from its features, pinout to its specifications, applications, cc2531 home assistant, cc2531 zigbee, texas instruments cc2531, also including CC2531 datasheet and so much more.
