RF Transceiver ICS Procurement Notes

Verify the suffix RHAT corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the specific temperature grade and pinout match the target PCB footprint. Ensure compliance with RoHS standards if applicable to the final product regulations. Cross-reference the manufacturer part number against official Texas Instruments documentation to avoid counterfeit components.

RF Transceiver ICS Selection Notes

Select this component when a combined MCU and BLE radio is necessary to reduce bill of materials count. Consider the 256 kB flash capacity for complex protocol stacks or large data buffers. Evaluate the 32 MHz processing speed against real-time execution requirements. Verify that the 2.4 GHz frequency band aligns with regional regulatory constraints and interference environments.

RF Transceiver ICS Part Context

This part belongs to the CC2540 family of Bluetooth Low Energy System-on-Chips from Texas Instruments. It serves as a foundational component for SimpleLink microcontrollers, enabling developers to create energy-efficient wireless solutions. The family supports various memory configurations and package options to suit different design constraints.

RF Transceiver ICS Replacement Considerations

CC2540F256RHAR is a compatible alternative offering identical functional specifications but packaged in cut tape rather than tape and reel. Both parts share the same core architecture and electrical characteristics, allowing for substitution based on manufacturing assembly preferences.
