NXP IW416

The IW416 is a highly integrated Wi-Fi 4 and Bluetooth 5.2 System-on-Chip (SoC) enabling a low-cost connectivity solution. Supporting a 1x1 SISO Wi-Fi operation in the 2.4 GHz and the 5 GHz band, the SoC provides a full-feature Wi-Fi subsystem with a peak PHY date rate of 150 Mbit/s. In addition to classic Bluetooth features, the IW416 enables Bluetooth 5.2 capabilities including Low Energy (LE), LE long range, LE 2 Mbps, and Periodic Advertising Sync Transfer (PAST).

With integrated transmit (Tx) PAs, receive (Rx) LNAs and Tx/Rx switches for the Wi-Fi and Bluetooth radios, the IW416 simplifies design allowing quick integration of either dual or single-antenna operation. The dual-antenna configuration enables simultaneous Wi-Fi and Bluetooth operation. With the single-antenna configuration, simultaneous 5 GHz Wi-Fi and Bluetooth is supported. In the 2.4 GHz band, the single-antenna configuration allows arbitrated transmit and receive operation of Wi-Fi and Bluetooth.

Promoting synergistic operation, the IW416 implements advanced Wi-Fi and Bluetooth co-existence hardware in conjunction with algorithms to optimize collaborative performance. In addition, support for external radio co-existence is provided through an external interface.

Available in both HVQFN and WLCSP packages, the IW416 supports an SDIO host interface for the Wi-Fi radio and a UART host interface for Bluetooth.
