Power-Up Sequence and Timing
Sona IF573 has two signals that allow the host to control power consumption by enabling or disabling the Bluetooth, WLAN, and internal regulator block.
Boot Mode


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.
External Antenna Integration
RF Antenna Connector Configuration
Antenna connectors for the SMT and M.2 2230 modules are designated as shown below.

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 Interface | GPIO_1 (Pin24) | LED_1# (Pin 65) |
|---|---|---|
| PCIe / UART | H | H |
| SDIO /UART | L | H |
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.
| WLAN Interface | M.2 1318 Pin | Internal GPIO |
|---|---|---|
| PCIe | 22 | GPIO_8 |
| SDIO | 18 | LHL_GPIO1 |
Note: This feature is subject to software support and not currently implemented.
32 KHz Crystal

- The calculated shelf life in a sealed bag is 12 months at <40℃ and <80% relative humidity.
- Once the packaging is opened, the SiP must be mounted (per MSL4/Moisture Sensitivity Level 4) within 72 hours at <30˚C and <60% relative humidity.
If the SiP is not mounted within 72 hours or if, when the dry pack is opened, the humidity indicator card displays >10% humidity, then the product must be baked for 48 hours at 125 ˚C (±5 ˚C).
Cautions when Removing the M.2 1318 from the Platform for RMA
- Bake the platform before removing the M.2 1318 module from the platform.
- Remove the M.2 1318 module by using a hot air gun. This process should be carried out by a skilled technician.
Recommended conditions:
One-side component platform:
- Set the hot plate at 280°C.
- Put the platform on the hot plate for 8~10 seconds.
Remove the device from platform.

Two-side components platform:
- Use two hot air guns.
- On the bottom, use a pre-heated nozzle (temp setting of 200~250°C) at a suitable distance from the platform PCB.
On the top, apply a remove nozzle (temp setting of 330°C). Heat until device can be removed from platform PCB.

- Remove the residue solder under the bottom side of device. (Note: Alternate module pictured as an example)

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:

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.
Qualification Steps When Referencing multiple existing designs, (unmodified) – Option 2a in the QPRDv3
For this qualification option, follow these steps:
- To start a listing, go to: https://qualification.bluetooth.com/
- Select Start the Bluetooth Qualification Process.
Product Details to be entered:
- Project Name (this can be the product name or the Bluetooth Design name).
- Product Description
- Model Number
- Product Publication Date (the product publication date may not be later than 90 days after submission)
- Product Website (optional)
- Internal Visibility (this will define if the product will be visible to other users prior to publication)
- If you have multiple End Products to list then you can select ‘Import Multiple Products’, firstly downloading and completing the template, then by ‘Upload Product List’. This will populate Qualification Workspace with all your products.
Specify the Design:
- Do you include any existing Design(s) in your Product? Answer Yes, I do.
- Enter the multiple DNs or QDIDs used in your, (for Option 2a two or more DNs or QDIDs must be referenced)
- Select ‘I’m finished entering DN’s
- Once the DNs or QDIDs are selected they will appear on the left-hand side, indicating the layers covered by the design (should show Core-Controller and Core Host Layers covered).
- What do you want to do next? Answer, ‘Combine unmodified Designs’.
- The Qualification Workspace Tool will indicate that a new Design will be created and what type of Core-Complete configuration is selected.
- An active TCRL will be selected for the design.
- Perform the Consistency Check, which should result in no inconsistencies
- If there are any inconsistencies these will need to be resolved before proceeding
- Save and go to Test Plan and Documentation
Test Plan and Documentation
- As no modifications have been made to the combined designs the tool should report the following message:
‘No test plan has been generated for your new Design. Test declarations and test reports do not need to be submitted. You can continue to the next step.’ - Save and go to Product Qualification fee
- As no modifications have been made to the combined designs the tool should report the following message:
Product Qualification Fee:
- It’s important to make sure a Prepaid Product Qualification fee is available as it is required at this stage to complete the Qualification Process.
- Prepaid Product Qualification Fee’s will appear in the available list so select one for the listing.
- If one is not available select ‘Pay Product Qualification Fee’, payment can be done immediately via credit card, or you can pay via Invoice. Payment via credit will release the number immediately, if paying via invoice the number will not be released until the invoice is paid.
- Once you have selected the Prepaid Qualification Fee, select ‘Save and go to Submission’
Submission:
- Some automatic checks occur to ensure all submission requirements are complete.
- To complete the listing any errors must be corrected
- Once you have confirmed all design information is correct, tick all of the three check boxes and add your name to the signature page.
- Now select ‘Complete the Submission’.
- You will be asked a final time to confirm you want to proceed with the submission, select ‘Complete the Submission’.
- Qualification Workspace will confirm the submission has been submitted. The Bluetooth SIG will email confirmation once the submission has been accepted, (normally this takes 1 working day).
Download Product and Design Details (SDoC):
- You can now download a copy of the confirmed listing from the design listing page and save a copy in your Compliance Folder
