Introduction

Overview

This document describes key hardware aspects of the Ezurio Sona™ IF573 series wireless modules providing either PCIe v3.0 Gen2 or SDIO 3.0 interface for WLAN connection and high-speed 4-wire UART interface for Bluetooth® connection. This document is intended to assist device manufacturers and related parties with the integration of this radio into their host devices. Data in this document is drawn from several sources and includes information found in the Infineon CYW55573MIWBGT data sheet issued on March 23, 2023, along with other documents provided by Infineon.

General Description

The Sona IF573 series wireless module is an integrated, small form factor Wi-Fi/Bluetooth module that is optimized for low-power mobile devices, featuring:

  • Wi-Fi 6E: Tri-band 2x2 MIMO IEEE 802.11a/b/g/n/ac/ax WLAN
  • Bluetooth® Dual Mode

The integration of all WLAN and Bluetooth functionality in a single package supports low cost and simple implementation along with flexibility for platform-specific customization. It is available in both M.2 2230 E-Key and M.2 1318 solder-down form factor.

This device is pre-calibrated and integrates the complete transmit/receive RF paths including bandpass filter, diplexer, switches, reference crystal oscillator, and power management units (PMU). Both variants support three integrated MHF4 connectors, with two ports for WLAN and one dedicated for Bluetooth. The M.2 1318 solder down module also supports an RF trace pin option for use with external antenna solutions.  For a list of certified antennas see Certified Antennas in the datasheet.
