Functional Descriptions
Programming & Firmware
The BL54L15/BL54L10 module is shipped from Ezurio manufacturing facilities with no firmware programmed.
BL54L15 BL54L10 Firmware Options
Firmware for use with the BL54L15/BL54L10 can be divided into the following types.
- Bootloader – This is the application that resides on the Application Core used to perform firmware updates of the Application and FLPR cores.
The MCU Boot or Trusted Firmware M Bootloaders are recommended to be used as the basis for the BL54L15 Bootloader functionality.
- Application – This is the main application running on the Application core. In interfaces with the integrated radio stack(s) and provides supplementary functionality in addition to the time critical activities performed for radio activity.
- Software Defined Peripheral – This is the application running on the RISC-V FLPR core.

Clocks
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.
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.

Notes:
Note 1 (GPIO):
- GPIO = General Input or Output (GPIO level voltage tracks VDD pin). AIN =Analog input.
- 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.
- Must connect all GND pads to host board PCB GND plane.
Note2 (Clock for serial interfaces or trace):
- Some peripherals (SPI, TWI, PDM, I2S, TRACE, GRTC) have clock signals. Dedicated clock pins have been optimized to ensure correct timing relationship between clock and data signal for these peripherals. Pins that can be used as clock signals are shown with pin name in red colour.
- The peripheral data signal must be configured to use pins close to the clock pin. This ensures that the
- internal paths from the peripheral to the pin have the same delay, so that the data and clock signals reach
- the pins at the same time.
- For high-speed signals, the printed circuit board (PCB) layout must use short PCB traces of identical length. This makes sure any delays are kept to a minimum and it assures close to identical delay and clock path.
Note 3 (Dedicated pins):
- UARTE20/21: Can use any pin son GPIO port P1. Can be connected across power domains to dedicated pin on P2.
- SPIM00: Has dedicated pins on GPIO port P2. For 32MHz operation, the pins must be configured using extra high drive E0/E1 configuration.
- SPIM20/21: Can use any pin son GPIO port P1. Can be connected across power domains to dedicated pin on P2.
- SPIS20/21: Can use any pin son GPIO port P1. Can be connected across power domains to dedicated pin on P2.
- TRACE: Has dedicated pins on GPIO port P2. For 32MHz operation, the pins must be configured using extra high drive E0/E1 configuration.
- GRTC: Has dedicated pins for clock and PWM output.
- TAMPC: Has dedicated pins for active shield inputs and outputs.
- FLPR: Uses dedicated pins on GPIO port P2 for emulated peripherals such as QSPI.
- RADIO: Uses dedicated pins on GPIO port P1 for antenna switch control (DFEGPIO for direction finding).
- NFC: Uses dedicated pins listed in pin definitions table.
Note 4 (SWDIO / SWCLK / nRESET / VDD / GND):
- Customer MUST bring out SWDIO, SWCLK, nRESET, VDD, GND for programming purposes.

Integration Guidelines
Host PCB Land Pattern and Antenna Keep-Out
PCB footprint - BL54L15 (DXF and Altium format) and SCH Symbol - BL54L15 (Altium format) can be found on the BL54L15 product page – https://www.ezurio.com/product/bl54l15-series-bluetooth-le-80215-4-nfc
BL54L10 use the same footprint of BL54L15.

All dimensions are in mm.
Notes:
- Ensure there is no copper in the antenna ‘keep out area’ on any layers of the host PCB. Also keep all mounting hardware or any metal clear of the area (Refer to 7.3.2) to reduce effects of proximity detuning the antenna and to help antenna radiate properly.
- For the best on-board antenna performance, the module 453-00001/453-00225 MUST be placed on the edge of the host PCB and preferably in the edge center and host PCB, the antenna “Keep Out Area” is extended (see Note 4).
- BL54L15 development board has the 453-00001 placed on the edge of the PCB board (and not in corner) for that the Antenna keep out area is extended down to the corner of the development board, see section 8.2 Host PCB Land Pattern and Antenna Keep-out for the 453-00001 and 453-00225.
- Ensure that there is no exposed copper under the module on the host PCB.
- You may modify the PCB land pattern dimensions based on their experience and/or process capability.

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.
Circuit (Overview and Checklist)
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-3.6V) 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 3.6V, 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.
By default module is out of reset when power applied to VDD_nRF pins (13K pull-up inside BL54L15/ BL54L10 (nRF54L15-QFAA/nRF54L10-QFAA)).
- 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.
PCB Layout
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).
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 453-00001/453-00225 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 keep-out 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. Below shows an example.

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.
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).
