CC8521RHAT

RF Transceiver ICS Overview

The CC8521RHAT is a Texas Instruments PurePath Wireless 2.4 GHz RF System-on-Chip designed for wireless digital audio streaming. It integrates an RF transceiver with a microcontroller unit, supporting up to two channels via USB. The device operates within a frequency range of 2.4 GHz to 2.48 GHz and supports maximum data rates of 5 Mb/s using 2-FSK or 8-FSK modulation formats. It functions on a power supply voltage ranging from 3 V to 3.6 V, delivering an output power of 3.5 dBm. The component is housed in a 40-VQFN package with exposed pad, suitable for surface mount installation across an operating temperature range of -40°C to +85°C.

RF Transceiver ICS Procurement Notes

Verify the specific suffix RHAT against the official Texas Instruments datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the required I2C, I2S, SPI, and USB interfaces for the target application. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to align with assembly processes.

RF Transceiver ICS Selection Notes

Select this component when a combined RF and MCU solution is required for low-power 2.4 GHz audio applications. Consider the 3.5 dBm output power and 5 Mb/s data rate limits against link budget requirements. Evaluate the 40-VQFN footprint constraints and thermal dissipation needs relative to the PCB layout capabilities.

RF Transceiver ICS Part Context

This part belongs to the CC852x series of PurePath Wireless SoCs. It shares architectural similarities with the CC8520 and CC8531 models but differs in specific interface configurations and integrated peripheral counts. The series targets cost-sensitive wireless audio markets requiring simplified development cycles through integrated baseband processing.

RF Transceiver ICS Replacement Considerations

CC8520RHAR is a documented variant within the same family offering similar RF performance with potentially different interface availability.
