RF Transceiver ICS datasheet and documents for CC2531F256RHAR

CC2531F256RHAR

RF Transceiver ICS Overview

The CC2531F256RHAR is a System on Chip (SoC) solution for IEEE 802.15.4, ZigBee, and RF4CE applications operating at 2.4 GHz. It integrates an 8051 microcontroller core with 256 kB of programmable flash memory and 8 kB of RAM. The device features a high-performance RF transceiver with -97 dBm sensitivity and +4.5 dBm output power. It supports USB connectivity and operates within a voltage range of 2 V to 3.6 V. The component is housed in a 40-lead VQFN package and functions across temperatures from -40°C to +125°C.

RF Transceiver ICS Feature Summary

Integrates a high-performance 8051 microcontroller with substantial non-volatile memory for complex protocol stacks.
Includes a robust 2.4 GHz radio transceiver optimized for low-power wireless communication standards.
Provides built-in USB interface capabilities for direct host connection without external controllers.

RF Transceiver ICS Applications

ZigBee and ZigBee Pro network nodes
IEEE 802.15.4 compliant wireless devices
Home automation sensor actuators
Industrial control systems requiring 2.4 GHz connectivity

RF Transceiver ICS Procurement Notes

Verify the specific suffix RHAR corresponds to the required tape-and-reel packaging configuration. Confirm that the 256 kB flash variant matches the firmware storage requirements. Ensure the VQFN-40 footprint aligns with the PCB layout specifications. Check moisture sensitivity levels for proper handling during assembly processes.

RF Transceiver ICS Selection Notes

Select this model when both significant program memory and integrated USB functionality are required. Compare against the CC2530 series if USB interfaces are unnecessary to reduce cost. Consider the CC2531F128 variant only if 128 kB of flash memory suffices for the application. Evaluate thermal performance within the specified industrial temperature range.

RF Transceiver ICS Part Context

This component belongs to the Texas Instruments CC2531 family of single-chip solutions. It is designed specifically for low-cost and low-power wireless applications. The part number indicates the specific memory size and package type within the broader product line.
