1 Product overview

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 coexistence is provided through an external interface. Available in both HVQFN68 and WLCSP76 packages with two operating temperature ranges of 0 to 70°C and -40 to 85°C, the IW416 supports a SDIO host interface for the Wi-Fi radio and a UART host interface for Bluetooth radio.
