Introduction
BluNor BT40F Series are powerful, highly flexible, ultra low power wireless modules using Nordic nRF5340
SoCs. With a dual core ARM
Cortex
TM
M33 MCU, embedded 2.4GHz multi-protocol transceiver, and an
integrated antenna, it allows faster time to market with reduced development cost.
BT40F Block Diagram
The following is a block diagram of BT40F. Antenna circuit and main clock are integrated. All 48 GPIOs of
nRF5340 can be accessed from main board. For lower power consumption at idle state, a 32.768 kHz crystal
can be added on the host board. Connection to an external NFC (Near Field Communication) antenna is
provided.
BlurNor BT40F is a sister module of BT840F, an nRF52840 module. The
physical size is the same.
There are 3 modules in the BT40F Series.

2. Codes Development Using Nordic Tools
Development tools by Nordic and other third party development tools recommended by Nordic should be used.
Nordic development environment for nRF5340 offers a clean separation between application code
development and embedded protocol stacks. This means compile, link and run time dependencies with the
embedded stack and associated debugging challenges are removed. The Bluetooth low energy and ANT stack
is a pre-compiled binary, leaving application code to be compiled stand-alone. The embedded stack interface
uses an asynchronous and event driven model removing the need for RTOS frameworks.
Over-The-Air DFU
The nRF52840 is supported by an Over-The-Air Device Firmware Upgrade (OTA DFU) feature. This allows for
in the field updates of application software and SoftDevice.
SoftDevices
The Nordic protocol stacks are known as SoftDevices and complement the nRF53 Series SoCs. All nRF53 Series are
programmable with software stacks from Nordic. This bring maximum flexibility to application development and allows
the latest stack version to be programmed into the SoC.
SoftDevices available from Nordic:
S***: Bluetooth low energy concurrent central/peripheral/observer/broadcaster stack.
Development Tools
Nordic Semiconductor provides a complete range of hardware and software development tools for the nRF53 Series
devices. nRF53 DK board is recommended for firmware development.
Nordic software development tools can be downloaded from the following webpage.

nRF5340 is a wireless ultra-low power multiple core System on Chip (SoC) integrating two fully programmable
Arm Cortex M33 processors, advanced security features, a range of peripherals, and a multiprotocol 2.4 GHz
transceiver. The transceiver supports Bluetooth low energy .
The two Arm Cortex M33 processors share the power, clock, and peripheral architecture with Nordic
Semiconductor nRF51, nRF52, and nRF91 Series of PAN/LAN SoCs, ensuring minimal porting efforts. The
application core is a full-featured Arm Cortex M33 processor including DSP instructions and FPU and running
at up to 128 MHz with 1MB of flash and 512 KB of RAM. The option to run the application processor at 64 MHz
allows th eCPU to increase energy efficiency. The network core is an Arm Cortex M33 processor with a
reduced feature set, designed for ultra-low power operation. It runs at a fixed 64 MHz frequency and contains
256 KB of flash and 64 KB of RAM.
The peripheral set offers a variety of analog and digital functionality enabling single chip implementation of a
wide range of applications. Arm trustZone technology, Arm cryptoCell-312, and supporting blocks for ysytem
protection and key management are embedded for the advanced security needed for IoT applications.

Mechanical Drawings
Mechanical drawings of BT40F, BT40, and BT40E is identical to that of BT840F, BT840, and BT840E,
respectively.
Two types of pins are available to meet different application requirements.
•
16 castellated pins for application needing limited number of IOs. SMT equipment is not required for
soldering castellated pins.
•
45 LGA (Land Grid Array) pins to access all 48 GPIOs of nRF52840 when needed.
