RF Transceiver Modules And Modems Procurement Notes

This component is designated as End-of-Life (EOL). Manufacturers have issued discontinuation notifications indicating that production will cease. Availability is currently restricted or limited. Engineers must verify current stock levels carefully before finalizing designs. Alternative solutions or replacement parts should be evaluated immediately to ensure supply chain continuity for ongoing projects.

RF Transceiver Modules And Modems Selection Notes

Select this module when a dedicated wireless co-processor is required to manage Wi-Fi and Bluetooth stacks independently of the main application processor. The NCP architecture reduces host CPU load. Ensure the design accommodates external antenna integration since this specific part number lacks an onboard antenna. Verify that the host system supports the necessary serial interfaces for data exchange.

RF Transceiver Modules And Modems Part Context

The SIWN917Y100LGNBA belongs to the SiWx917Y family of wireless modules by Silicon Labs. This series targets energy-sensitive IoT applications by combining ultra-low-power connectivity with significant on-chip memory. The family offers various configurations including SoC and RCP modes, but this specific variant is optimized for network co-processor operation without integrated RF components.

RF Transceiver Modules And Modems Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the EOL status. Designers should consult official Silicon Labs lifecycle notices for recommended alternatives within the SiWx917 series or newer generations.
