Codes Development Using Nordic Tools Development tools by Nordic and other third party development tools recommended by Nordic should be used . Easy, fast and safe code development Nordic development environment for nRF52840 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 nRF52 Series SoCs. All nRF52 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:
S140: 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 nRF52 Series devices. nRF52 DK board is recommended for firmware development. Nordic software development tools can be downloaded from the following webpage. http://infocenter.nordicsemi.com/index.jsp?topic=/com.nordic.infocenter.nrf52/dita/nrf52/development/nrf52_dev_kit.htm l&cp=1_1 5 Bluetooth Low Energy(BLE) 5 Module BT840FVer 0.91 Nov. 2017 draft 3. Product Descriptions Brief description of nRF52840 SoC is provided. For full description of the SoC, please download from Nordic Semiconductor website. https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy Block Diagram of nRF52840 6 Bluetooth Low Energy(BLE) 5 Module BT840FVer 0.91 Nov. 2017 draft The following is a block diagram of Nordic nRF52840 Bluetooth Low Energy (BLE) SoC. Arrows with white heads indicate signals that share physical pins with other signals. The 32 bit ARM Cortex M4F MCU with hardware supports for DSP instructions and floating point operations, code density and execution speed are higher than other Cortex M MCU. The Programmable Peripheral Interconnect (PPI) system provides a 20-channel bus for direct and autonomous system peripheral communication without CPU intervention. This brings predictable latency times for peripheral to peripheral interaction and power saving benefits associated with leaving CPU idle. The device has 2 global power modes 7 Bluetooth Low Energy(BLE) 5 Module BT840FVer 0.91 Nov. 2017 draft ON/OFF, but all system blocks and peripherals have individual power management control which allows for an automatic switching RUN/IDLE for system blocks based only on those required/not required to achieve particular tasks. The radio supports Bluetooth low energy and ANT. Output power is scalable from a maximum of +8dBm down to -20 dBm in 4dB steps. Sensitivity is increased to -96 dBm to -89 dBm, depending on data rate. Sensitivity for BLE is -96 dBm, and -92.5 dBm for ANT. The NFC block supports NFC-A tags with proximity detection and Wake-on-field from low power mode. The NFC enables Out-Of-Band (OOB) Bluetooth pairing of devices and thus greatly simplifying deployment. ARM Trustzone CryptoCell 310 ARM TrustZone CryptoCell-310co-processor is a security subsystem which provides Root of Trust (RoT) and cryptographic services for a device. CryptoCell services are available to the application through a software library API, not a hardware register interface. The following cryptographic features are provided.

For the best Bluetooth range performance, the antenna area of module shall extend 9.8 mm outside the edge of host PCB board, or 9.8 mm outside the edge of a ground plane. The next choice is to place a module on a corner of host PCB, the antenna area shall extend 9.8 mm from the edge of ground plane. Ground plane shall be at least 5 mm from the edge of the antenna area of module. We dont recommend mounting BT840F module in the middle of a host PCB. For the best Bluetooth range performance, keep all external metal at least 30mm from the antenna area. 15 Bluetooth Low Energy(BLE) 5 Module BT840FVer 0.91 Nov. 2017 draft Host Board Design for Low Cost or Long Range On nRF52 series SoCs, Nordic offers various memory options and protocol supports. Fanstel offers various antenna and power amplifier options. A host board can be designed to accommodate these nRF52 modules. Our suggestions for host PCB design:
If your main goal is minimum PCB cost, use a 2-sided PCB. Use library component from EV BT832 Gerber files, can be downloaded from http://www.fanstel.com/download-document/.It has 16 castellated pins plus 24 LGA pins. BT840F library component can be used. However, signal routing can be difficult on a 2-sided PCB. Be sure of no metal contact in the area of 21 additional BT840F pins. BT840F can be mounted on a BT832 pad. If you main goal is maximum wireless range, use a 4 or more layers PCB. Use library component from EV BT840F V4 or newer Gerber files, can be downloaded from http://www.fanstel.com/download-document/.It has 16 castellated pins plus 45 LGA pins. As much ground plane under BT840F, on top side of host PCB as possible. Use EV BT840F V4 Gerber files as an example. If your products may need wireless range of 1350 meters at 1 Mbps, allocate physical space for a 15x28x1.9mm module. This larger module size is required to accommodate Skyworks SKY66112 power amplifier. Dont use P0.06 (BT840F pin B4), P0.17 (BT840F pin C3), and P0.19 (BT840F pin D2) on the host board. These pins are used to control SKY66112 power amplifier. 16 Bluetooth Low Energy(BLE) 5 Module BT840FVer 0.91 Nov. 2017 draft 4. BT840F Evaluation Board Communicating with a PC A quick and easy way to evaluate BT840F is to use a PC as the host processor. Connect the development board EV-BT840F to a PC with an USB cable. Then, SetS1, BT840F is set to command mode. PC will communicate with BT840F. Set switch S1 to the other position, BT840F is set to data mode. PC will communicate with a remote device through BT840F Bluetooth wireless connection.

The circuitry to the left of micro USB connector, J16 produces periodic load to prevent portable smartphone charger from shutting down. Suggestion for Battery Power Application Standby current consumption is important for battery-powered product. We suggest adding a 32.768 kHz crystal and 2 capacitors on host board. The 32MHz main clock wont be active at idle state to save power. Two inductors required for on-board DC to DC converter are inside BT840F. You can enable DCDC converter to have lower power consumption. 19 Bluetooth Low Energy(BLE) 5 Module BT840FVer 0.91 Nov. 2017 draft 5.
