## **3.4 Clocks**
## **3.4.1 HFXO - 32MHz crystal oscillator and nRF54L15/nRF54L10 internal load capacitor mandatory setting**
The BL54L15/BL54L10 module contains the 32 MHz crystal, but the load capacitors to create 32MHz crystal oscillator circuit are inside the nRF54L15/nRF54L10 chipset. Customer can set the internal nRF54L15/nRF54L10 capacitors from 4 pF to 17 pF in 0.25pF if needed or use default value without changing.
The 32 MHz crystal inside the BL54L15/BL54L10 module is a high accuracy crystal (±15 ppm at room temperature) that helps with radio operation and reducing power consumption in the active modes.
## **3.4.2 LFCLK – Low Frequency clock source**
There are four possibilities (see figure 3) for the low frequency clock (LFCLK) and options are:
**LFRC (32.768kHz RC oscillator):** The Internal 32.768 kHz RC oscillator (LFRC) is fully embedded in nRF54L15/nRF54L10 (and does not require additional external components) with an accuracy ±250 ppm (after calibration of LFRC at least every eight seconds using the HFXO as a reference oscillator).
**LFXO (32.768kHz crystal oscillator):** For higher LFCLK accuracy (greater than ±250ppm accuracy is required), the low frequency crystal oscillator (LFXO) must be used. To use LFXO, a 32.768kHz crystal must be connected between the XL1 and XL2 pins and the load capacitance between each crustal terminal and ground. Optionally internal (to nRF54L15/nRF54L10) capacitor of maximum 18 pF in 0.5 pF steps are provided on pins XL1 and XL2.
**Low frequency (32.768 kHz) external source** : The 32.768 kHz oscillator (LFXO) is designed to work with external sources
**LFSYNTH (32.768kHz Synthesised clock) from HFCLK (LFSYNTH):** The LFCLK can be synthesised from the HFCLK source. LFSYNTH depends on the HFCLK to run. The accuracy of the LFCLK clock with LFSYNTH as a source assumes the accuracy of the HFCLK. If high accuracy is required, the HFCLK must generated from the HFXO. Using the LFSYNT clock removes the requirement for an external 32.768kHz crystal but the increases the average power consumption as the HFCLK will turned on in the system.

## 6 SW requirements related to hardware
## **6.1 32MHz crystal internal load capacitor setting**
BL54L15/ BL54L10 module contains the 32 MHz crystal but the load capacitors to create 32 MHz crystal oscillator circuit are inside the nRF54L15/ nRF54L10 chipset. Customer can set the internal nRF54L15/nRF54L10 capacitors from 4 pF to 17 pF in 0.25pF if needed, or use default value without changing.
## 7 Hardware Integration Suggestions
## **7.1 Circuit**
The BL54L15/ BL54L10 is easy to integrate, requiring one mandatory external 10uF capacitor on customers board and apart from that those components which customer require for development and in your end application.
The following are suggestions for your design for the best performance and functionality.
## **Checklist (for Schematic):**
- **BL54L15/ BL54L10 power supply:**
Normal voltage mode power supply mode is entered when the external supply voltage (1.7V-3.5V) is connected to both VDD_nRF pin (pin26).
External power source should be within the operating range, rise time and noise/ripple specification of the BL54L15/ BL54L10. Add decoupling capacitors for filtering the external source. Power-on reset circuitry within BL54L15/ BL54L10 series module incorporates brown-out detector, thus simplifying your power supply design. Upon application of power, the internal power-on reset ensures that the module starts correctly.
- **AIN (ADC) and GPIO pin IO voltage levels**
BL54L15/BL54L10 GPIO voltage levels are at VDD_nRF. Ensure input voltage levels into GPIO pins are at VDD_nRF also. Ensure ADC pin maximum input voltage for damage is not violated.
- **AIN (ADC) impedance and external voltage divider setup**
If you need to measure with ADC a voltage higher than 3.5V, you can connect a high impedance voltage divider to lower the voltage to the ADC input pin.
- **SWD**
This is REQUIRED for loading firmware. MUST wire out the SWD two wire interface on host design. Five lines should be wired out, namely SWDIO, SWDCLK, nRESET, GND and VDD.
- **UART and flow control (CTS, RTS)**
Required if customer requires UART.
- **TWI (I2C)**
It is essential to remember that pull-up resistors on both SCL and SDA lines are required, the value as per I2C standard. nRF54L15/ nRF54L10 can provide 13K Ohms typical pull up values internally. For other values, fit external pull-up resistor on both SCL and SDA as per I2C specification to set speed. The I2C specification allows a line capacitance of 400pF.
- **QSPI, High Speed SPI, High speed TWI (I2C, 1Mbps) and Trace**
- High-Speed SPI, TWI and Trace come on dedicated GPIO pins only. Other lower speed SPI and TWI can come out on any GPIO pins. For all high-speed signal, the printed circuit board (PCB) layout must ensure that connections are made using short PCB traces.
- **GPIO pins**
If GPIO is selected as an input, ensure the input is not floating (which can cause current consumption to drive with time in low power modes (such as System ON Idle), by selecting the internal pull up or pull down.
-
-
## **NFC antenna connector**
- To make use of the Ezurio flexi-PCB NFC antenna (part # 0600-00061), fit connector:
- Description – FFC/FPC Connector, Right Angle, SMD/90d, Dual Contact,1.2 mm Mated Height
- Manufacturer – Molex
- Manufacturers Part number – 512810594
Add tuning capacitors of 300 pF on NFC1 pin to GND and 300 pF on NFC2 pins to GND if the PCB track length is similar as development board.
-
## **nRESET pin (active low)**
Hardware reset. Wire out to push button or drive by host.
20
© Copyright 2025 Ezurio All Rights Reserved
https://www.ezurio.com/
**BL54L15 / BL54L10 Series** Datasheet
By default module is out of reset when power applied to VDD_nRF pins (13K pull-up inside BL54L15/ BL54L10 (nRF54L15-QFAA/nRF54L10QFAA)).
- **Optional External 32.768kHz crystal**
If the optional external 32.768kHz crystal is needed, then use a crystal that meets specification and add load capacitors (either inside nRF54L15-QFAA/nRF54L10-QFAA or discrete capacitors outside BL54L15/BL54L10 (nRF54L15-QFAA/nRF54L10-QFAA) whose values should be tuned to meet all specification for frequency and oscillation margin.
## **7.2 PCB Layout on Host PCB - General**
## **Checklist (for PCB):**
- MUST locate BL54L15/ BL54L10 module close to the edge of PCB (mandatory for the 453-00001/453-00225 for on-board PCB trace antenna to radiate properly).
- Use solid GND plane on inner layer (for best EMC and RF performance).
- All module GND pins MUST be connected to host PCB GND.
- Place GND vias close to module GND pads as possible.
- Unused PCB area on surface layer can flooded with copper but place GND vias regularly to connect the copper flood to the inner GND plane. If GND flood copper is on the bottom of the module, then connect it with GND vias to the inner GND plane.
- Route traces to avoid noise being picked up on VDD_nRF supply and AIN (analogue), GPIO (digital) traces and high-speed traces.
- Ensure no exposed copper is on the underside of the module (refer to land pattern of BL54L15/BL54L10 development board).
## **7.3 PCB Layout on Host PCB for the 453-00001 and 453-00225**
## **7.3.1 Antenna Keep-out on Host PCB**
The 453-00001/453-00225 has an integrated PCB trace antenna and its performance is sensitive to host PCB. It is critical to locate the 45300001/453-00225 on the edge of the host PCB (or corner) to allow the antenna to radiate properly. Refer to guidelines in section **PCB land pattern and antenna keep-out area for the 453-00001/453-00225** . Some of those guidelines repeated below.
- Ensure there is no copper in the antenna keep-out area on any layers of the host PCB. Keep all mounting hardware and metal clear of the area to allow proper antenna radiation.
- For best antenna performance, place the 453-00001/453-00225 module on the edge of the host PCB, preferably in the edge center.
- The BL54L15 development board (453-00001-K1) has the 453-00001 module on the edge of the board (not in the corner). The antenna keepout area is defined by the BL54L15 development board which was used for module development and antenna performance evaluation is shown in Figure 6, where the antenna keep-out area is ~5mm wide, ~28.6mm long; with PCB dielectric (no copper) height ~1.57mm sitting under the 453-00001 PCB trace antenna module. Bl54L10 module (453-00225) please follow the same design of BL54L15.
- The 453-00001 PCB trace antenna is tuned when the 453-00001 is sitting on development board (host PCB) with size of 113 mm x 63.5 mm x 1.6mm.
- A different host PCB thickness dielectric will have small effect on antenna.
- The antenna-keep-out defined in the 8.2 Host PCB Land Pattern and Antenna Keep-out for the 453-00001 and 453-00225 section.
- Host PCB land pattern and antenna keep-out for the BL54L15/BL54L10 applies when the 453-00001/453-00225 is placed in the edge of the host PCB preferably in the edge center. **Error! Reference source not found.** shows an example.

## **Antenna Keep-out Notes:**
**Note 1** The BL54L15/BL54L10 module is placed on the edge, preferably edge centre of the host PCB.
**Note 2** Copper cut-away on all layers in the Antenna Keep-out area under the 453-00001/453-00225 on host PCB.

## **7.3.2 Antenna Keep-out and Proximity to Metal or Plastic**
## **Checklist (for metal /plastic enclosure):**
- Minimum safe distance for metals without seriously compromising the antenna (tuning) is 40 mm top/bottom and 30 mm left or right.
- Metal close to the 453-00001/453-00225 PCB trace monopole antenna (bottom, top, left, right, any direction) will have degradation on the antenna performance. The amount of that degradation is entirely system dependent, meaning you will need to perform some testing with your host application.
- Any metal closer than 20 mm will begin to significantly degrade performance (S11, gain, radiation efficiency).
- It is best that you test the range with a mock-up (or actual prototype) of the product to assess effects of enclosure height (and materials, whether metal or plastic) and host PCB ground (GND plane size).
## **7.4 External Antenna Integration with BL54L15/BL54L10 MHF4 variant (453-00044/453-**
## **00226)**
Please refer to the regulatory sections for FCC, ISED, CE, MIC, UKCA and RCM details of use of BL54L15 with external antennas in each regulatory region.
The BL54L15/BL54L10 family has been designed to operate with the below external antennas (with a maximum gain of 2.32 dBi). The required antenna impedance is 50 ohms. See Table 4. External antennas improve radiation efficiency.

## 13 Bluetooth Qualification Process
## **13.1 Overview**
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
## **13.2 Scope**
This guide is intended to provide guidance on the Bluetooth Qualification Process for End Products that reference a single existing design, that has not been modified, (refer to Section 3.2.1 of the Qualification Program Reference Document v3).
This option applies to a Member qualifying a Product that includes an existing Design that has a DN, QDID, or DID and that Design has not been modified (e.g., rebranding a Qualified Product from another Member). The Design identified by the DN, QDID, or DID may only implement Bluetooth Specifications that are active or deprecated at the time of Submission. No modifications may be made to the Design, including changes to the ICS Form.
Changes to the Product outside the Design are allowed, including:
- Enabling technologies
- Changes to the industrial design
- Changes to the communication technology other than Bluetooth
- Changes to the features that are unrelated to Bluetooth, branding, packaging, colour, shape, Product name, or Model number
Members are responsible for assessing that modifications to the Product outside of the Design do not affect compliance with Bluetooth Specifications or result in a change to the ICS Form.
For the purposes of this document, it is assumed that the member is combining a single unmodified Core-Complete Configuration.
## **13.3 Qualification Steps When Referencing a single existing design, (unmodified) – Option 1**

- 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.
4. Specify the Design:
- Do you include any existing Design(s) in your Product? Answer Yes, I do.
- Enter the single DN or QDID used in your, (for Option 1 only one DN or QDID can be referenced)
- Once the DN or QDID is selected it will appear on the left-hand side, indicating the layers covered by the design.
- Select ‘I’m finished entering DN’s
- What do you want to do next? Answer, ‘Use this Design without Modification’
- Save and go to Product Qualification Fee
5. 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’
6. 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).
7. Download Product and Design Details:
- a. You can now download a copy of the confirmed listing from the design listing page and save a copy in your Compliance Folder
