RF Transceiver ICS Procurement Notes

Verify the specific ordering suffix RHAR corresponds to the VQFN-40 package and reel packaging configuration required for your assembly process. Confirm that the firmware environment aligns with the SimpleLink development tools provided by Texas Instruments. Ensure compliance with RoHS directives as indicated in the official product specifications before finalizing procurement orders.

RF Transceiver ICS Selection Notes

Select this component when a combined MCU and BLE radio with native USB support is required. It is suitable for designs needing moderate program memory capacity and multiple analog inputs. Consider alternative models if higher RF output power or different pin counts are necessary. Evaluate the thermal performance requirements for the VQFN-40 package in dense PCB layouts.

RF Transceiver ICS Part Context

This part belongs to the CC254x family of Bluetooth Low Energy SoCs from Texas Instruments. These devices are designed to simplify the development of wireless IoT solutions by integrating all necessary components onto a single chip. The family offers various memory configurations to suit different application complexity levels while maintaining compatibility with the same software stack.

RF Transceiver ICS Replacement Considerations

CC2541F128RHAR: Offers similar functionality but lacks the integrated USB controller found in the CC2540 series. CC2540F256RHAR: Provides double the flash memory (256 kB) while retaining the same interface and package characteristics. Verify pin-to-pin compatibility and firmware adaptation requirements when substituting these variants.
