CC2571RHAR

RF Transceiver ICS Overview

The CC2571RHAR is an 8-channel ANT™ RF network processor manufactured by Texas Instruments. It integrates a high-performance 8051 microcontroller with a 2.4 GHz radio transceiver in a VQFN-40 package. The device supports multiple data rates including 1 Mbps and 500 kbps for ANT protocol communication. Operating voltage ranges from 2 V to 3.6 V, with current consumption of approximately 23.7 mA during reception and 25.9 mA to 34.3 mA during transmission. It functions within a temperature range of -40°C to +85°C.

RF Transceiver ICS Feature Summary

• Integrates an 8051 microcontroller core with a 2.4 GHz radio transceiver for combined processing and wireless connectivity
• Supports up to eight simultaneous ANT channels for multi-device sensor networking
• Includes hardware acceleration for the ANT protocol stack to reduce host CPU load

RF Transceiver ICS Applications

• Wireless sensor networks using ANT protocol
• Health and fitness tracking devices
• Sports and outdoor activity monitoring equipment

RF Transceiver ICS Procurement Notes

Verify that the specific suffix RHAR corresponds to the VQFN-40 surface-mount package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure handling procedures account for moisture sensitivity classification as indicated in the datasheet. Cross-reference the part number against the latest Texas Instruments product change notices to ensure component equivalence.

RF Transceiver ICS Selection Notes

Select this component when an application requires dedicated ANT protocol handling with integrated radio capabilities. The built-in 8051 core allows for standalone operation without a separate main controller. Consider the power consumption profiles during active transmission and reception phases relative to battery life requirements. Evaluate the thermal performance within the specified operating temperature range for the target enclosure design.

RF Transceiver ICS Part Context

This part belongs to the CC2571 series of RF network processors designed specifically for ANT technology applications. It serves as a bridge between host systems and peripheral sensors. The RHAR designation indicates the specific tape-and-reel packaging configuration suitable for automated surface-mount assembly processes.

RF Transceiver ICS Replacement Considerations

The CC2571RHAT is a pin-compatible alternative within the same series offering identical functionality in a different packaging format.
