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.

The Sona IF573 series device supports IEEE 802.11ax tri-band (2.4/5/6 GHz) 2x2 MIMO with data rates up to MCS11 (287 Mbps PHY data rate for 2.4 GHz band and 1.2 Gbps PHY data rate for 5/6 GHz). The device has a dedicated Bluetooth port for best Wi-Fi + Bluetooth coexistence performance. The device’s low power consumption, radio architecture and power management unit (PMU) proprietary power save technologies allow for extended battery life.

In addition, its tri-band IEEE 802.11ax and Bluetooth radio includes full digital MAC and baseband engines that handle all 802.11 CCK/OFDM/OFDMA® 2.4/5/6 GHz and Bluetooth Core 6.0 (Basic Rate, Enhanced Data Rate, and Bluetooth Low Energy) baseband and protocol processing.

Boot Mode

image-20251230-185926.pngimage-20251230-190014.png

Description of Control Signals

  • WL_REG_ON: Used to power up the WLAN. When this pin is high, the internal regulators are enabled and the WLAN section is out of reset. When this pin is low the WLAN section is in reset.  This signal is connected to the W_DISABLE1# pin on the M.2 interface.
  • BT_REG_ON: Used to power up the Bluetooth section. If both the BT_REG_ON and WL_REG_ON pins are low, the regulators are disabled. When this pin is low and WL_REG_ON is high, the Bluetooth section is in reset.  This signal is connected to the W_DISABLE2# pin on the M.2 interface.
  • M.2 1318 - VBAT and VDDIO should not rise 10% - 90% faster than 40 microseconds.
  • M.2 1318 - VBAT should be up before or at the same time as VDDIO. VDDIO should NOT be present first or be held high before VBAT is high.

PCI Express Specifications

The Sona IF573 series wireless module supports the PCIe interface, which provides high-performance serial I/O interconnects and is also protocol compliant and electrically compatible with the PCI Express Base Specification v3.0 running at Gen2 speeds.

Organization of the PCIe core is in logical layers: Transaction Layer, Data Link Layer, and Physical Layer, as shown in Figure 7. A configuration or link management block is provided for enumerating the PCIe configuration space and supporting generation and reception of System Management Messages by communicating with PCIe layers.

Each layer is partitioned into dedicated transmit and receive units that allow point-to-point communication between the host and Sona IF573 device. The transmit side processes outbound packets whereas the receive side processes inbound packets. Packets are formed and generated in the Transaction and Data Link Layer for transmission onto the high-speed links and onto the receiving device. A header is added at the beginning to indicate the packet type and any other optional fields.

PCM Specifications

PCM Interface

The Sona IF573 series wireless module supports a PCM interface. The PCM interface on the Sona IF573 series wireless module can connect to linear PCM codec devices in Master/Slave mode. In Master mode, the Sona IF573 generates the BT_PCM_CLK and BT_PCM_SYNC signals, and in Slave mode, these signals are provided by another master on the PCM interface and are input to the Sona IF573 module.

The configuration of the PCM interface may be adjusted by the host through the use of vendor-specific HCI commands.

Integration Guidelines

Antenna Characteristics

Circuit (Overview and Checklist)

The following is a list of RF layout design guidelines and recommendation when installing a Ezurio radio into your device.

  • Do not run antenna cables directly above or directly below the radio.
  • Do not place any parts or run any high-speed digital lines below the radio.
  • Ensure that there is the maximum allowable spacing separating the antenna connectors on the Ezurio radio from the antenna. In addition, do not place antennas directly above or directly below the radio.
  • Ezurio recommends the use of a double-shielded cable for the connection between the radio and the antenna elements.
  • Be sure to put a 10uF/16V/0603 capacitor on EACH 3.3V power pin. Place the capacitor as close as possible to the pin to ensure correct PMU operation.
  • Use proper electro-static-discharge (ESD) procedures when installing the Ezurio radio module. To avoid negatively impacting Tx power and receiver sensitivity, do not cover the antennas with metallic objects or components.

Host Platform Implementation Details

M.2 1318 WLAN Interface Selection

The Sona IF573 M.2 1318 module must be configured for either PCIe or SDIO WLAN interface.  Configuration is done with resistor strapping as specified below.

WLAN/Bluetooth InterfaceGPIO_1 (Pin24)LED_1# (Pin 65)
PCIe / UARTHH
SDIO /UARTLH

Note: The M.2 2230 E-Key module strapping is implemented on the M.2 carrier board.

Bluetooth Interface Requirements

The CYW55573 Bluetooth CPU core requires the UART_CTS input to be held low at the point the BT_REG_ON (W_DISABLE2#) signal goes high to enable secure firmware download.  In addition, the HCI interface uses the standard H4 protocol which requires four-wire hardware handshaking. 

This requires that the host implement GPIO control over BT_REG_ON/W_DISABLE2# and implement full RTS/CTS handshaking.

Low Power Clock

The Sona IF573 requires a 32KHz clock on the SUSCLK input.  This clock drives various internal state machines and must be provided by the host even if low power operation is not needed.

WL_DEV_WAKE Mapping

The WL_DEV_WAKE feature is mapped to different pins on the M.2 1318 module depending on the WLAN interface selection. See below for details.

Bluetooth SIG Qualification

The Bluetooth Qualification Process promotes global product interoperability and reinforces the strength of the Bluetooth® brand and ecosystem to the benefit of all Bluetooth SIG members. The Bluetooth Qualification Process helps member companies ensure their products that incorporate Bluetooth technology comply with the Bluetooth Patent & Copyright License Agreement and the Bluetooth Trademark License Agreement (collectively, the Bluetooth License Agreement) and Bluetooth Specifications.

The Bluetooth Qualification Process is defined by the Qualification Program Reference Document (QPRD) v3.

To demonstrate that a product complies with the Bluetooth Specification(s), each member must for each of its products:

  • Identify the product, the design included in the product, the Bluetooth Specifications that the design implements, and the features of each implemented specification
  • Complete the Bluetooth Qualification Process by submitting the required documentation for the product under a user account belonging to your company

The Bluetooth Qualification Process consists of the phases shown below:

image-20250916-191649.png

To complete the Qualification Process the company developing a Bluetooth End Product shall be a member of the Bluetooth SIG.  To start the application please use the following link: Apply for Adopter Membership

Scope

This guide is intended to provide guidance on the Bluetooth Qualification Process for End Products that reference multiple existing designs, that have not been modified, (refer to Section 3.2.2.1 of the Qualification Program Reference Document v3).

For a Product that includes a new Design created by combining two or more unmodified designs that have DNs or QDIDs into one of the permitted combinations in Table 3.1 of the QPRDv3, a Member must also provide the following information:

  • DNs or QDIDs for Designs included in the new Design
  • The desired Core Configuration of the new Design (if applicable, see Table 3.1 below)
  • The active TCRL Package version used for checking the applicable Core Configuration (including transport compatibility) and evaluating test requirements

Any included Design must not implement any Layers using withdrawn specification(s).

When creating a new Design using Option 2a, the Inter-Layer Dependency (ILD) between Layers included in the Design will be checked based on the latest TCRL Package version used among the included Designs.

For the purposes of this document, it is assumed that the member is combining unmodified Core-Controller Configuration and Core-Host Configuration designs, to complete a Core-Complete Configuration.
