CC2520RHDT

RF Transceiver ICS Overview

The CC2520RHDT is a second-generation 2.4 GHz IEEE 802.15.4 and ZigBee compliant RF transceiver manufactured by Texas Instruments. It integrates an O-QPSK modulator/demodulator, digital baseband processing, and a high-performance microcontroller unit within a compact 28-pin VQFN package. The device operates on a supply voltage range of 1.8 V to 3.8 V and supports data rates up to 250 kbps. Key electrical specifications include a maximum output power of 5 dBm, a receiver sensitivity of -98 dBm, and a transmission current of 33.6 mA. It features a 4-wire SPI interface, 768 bytes of RAM, and six general-purpose input/output pins.

RF Transceiver ICS Procurement Notes

Verify the specific suffix RHD corresponds to the 28-pin VQFN package variant when sourcing components. Confirm that the operating temperature range meets the requirements of the intended deployment environment, as the device is rated for industrial temperatures from -40°C to +125°C. Ensure that the supply voltage provided to the system remains within the specified 1.8 V to 3.8 V limits to guarantee proper functionality and prevent damage to the integrated circuit.

RF Transceiver ICS Selection Notes

Select this component for designs requiring a dedicated RF transceiver paired with a microcontroller for ZigBee or IEEE 802.15.4 protocols. It is appropriate for applications needing moderate output power and high sensitivity in a small form factor. Consider the integration of the MCU if additional processing resources are required beyond basic packet handling. Evaluate the pin count and package size against the available PCB space constraints before finalizing the design.

RF Transceiver ICS Part Context

This part belongs to the CC2520 family of RF transceivers designed for low-cost, low-power wireless applications. It serves as a companion to the CC2530 and CC2540 series, which combine similar RF capabilities with larger memory spaces. The CC2520 focuses specifically on the physical and MAC layers of the protocol stack, offloading these tasks from the main host processor to improve system efficiency and reduce overall power consumption in complex network topologies.
