RF Transceiver ICS Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life (EOL) notices, as this part may have specific lifecycle constraints. Ensure packaging specifications match design requirements, noting the Tape & Reel format. Validate that the 56-VFQFN footprint aligns with PCB layout guidelines before finalizing procurement orders.

RF Transceiver ICS Selection Notes

Select this component for designs requiring integrated Bluetooth v3.0 connectivity with moderate data throughput needs. Consider the 56-pin QFN package size for space-constrained layouts. Evaluate power budgets against the specified 63mA transmit current. Ensure the host system supports the required 3V logic levels and available serial interfaces for proper communication protocol implementation.

RF Transceiver ICS Part Context

This part belongs to the Infineon CYW20733 series, which combines RF and MCU functionalities. It serves as a solution for compact wireless applications.
