RF Transceiver ICS Procurement Notes

This component is officially classified as obsolete by Infineon Technologies and is no longer manufactured. Availability is restricted to remaining stock from previous production runs or third-party distributors. Verification of part authenticity and condition is critical due to the end-of-life status. Designers should confirm compatibility with existing supply chains and consider long-term sustainability risks associated with discontinued components before finalizing procurement plans.

RF Transceiver ICS Selection Notes

Engineers evaluating this part must account for its obsolete status when planning new designs. The integration of BLE 4.2 functionality and specific memory sizes suits applications requiring moderate processing power with wireless capabilities. Compatibility checks for the 76-pin FBGA package and operating voltage ranges are essential. Alternative solutions should be identified to ensure supply chain stability for future production phases.

RF Transceiver ICS Part Context

The CYBL11573 series belongs to Infineon's PRoC (Programmable System-on-Chip) family, designed to simplify Bluetooth development. This specific model combines the radio front-end with a microcontroller unit, reducing board space and component count. It targets applications needing integrated wireless control without external protocol controllers.

RF Transceiver ICS Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult official replacement guides or contact manufacturer support for validated alternatives.
