BMD-340 - Data sheet 1 Functional description The BMD-340 is an advanced, highly flexible, ultra-low power multiprotocol System on Module (SoM) that enables Bluetooth 5 low energy and IEEE 802.15.4 (Thread and Zigbee) connectivity for portable, and extremely low power embedded systems. With an Arm® Cortex®-M4 with FPU processor, integrated 2.4G Hz transceiver, and an integrated antenna, the BMD-340 provides a complete RF solution allowing faster time to market with reduced development costs. Providing full use of the Nordic Semiconductor nRF52840’s capabilities and peripherals, the BMD-340 can power the most demanding applications, all while simplifying designs and reducing BOM costs. The BMD-340 is an ideal solution for designs that require Bluetooth 5 features or 802.15.4 based networking for Thread and Zigbee. Increased integration with built in USB and 5.5 V compatible DC/DC supply reduces design complexity and BOM cost, while expanding possible applications. BMD-340 designs are footprint compatible with the BMD-300/301/330/360, providing low-cost flexibility for tiered product lineups. 1.1 Features • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • Based on the Nordic Semiconductor nRF52840 SoC Bluetooth 5 PHYs: LE 1M, LE 2M, and LE Coded (long range) Bluetooth 5 features: Advertising Extensions, Channel Selection Algorithm #2 Bluetooth mesh IEEE 802.15.4 with Thread and Zigbee support Complete RF solution with an integrated PCB antenna Integrated DC-DC converter No external components required Arm® Cortex®-M4 with FPU 32-bit processor Arm® TrustZone® Cryptocell 310 security True random number generator Serial Wire Debug (SWD) Nordic Semiconductor SoftDevice ready 1 MB embedded flash memory 256 KB RAM 48 General Purpose I/O Pins 12-bit/200 KSPS ADC One Full-Speed USB (12 Mbps) Four SPI Master/Slave (8 Mbps) Quad SPI with Execute in Place (XIP) PWM 4 blocks x 4-channels each General Purpose and Low power comparators Temperature sensor Two 2-wire Master/Slave (I2C compatible) I2S audio interface Two UARTs (w/ CTS/RTS and DMA) 20-channel CPU independent Programmable Peripheral Interconnect (PPI) Quadrature Demodulator (QDEC) 5 x 32 bit timer/counters 3 x 24 bit Real Timer Counters (RTC) NFC-A tag interface for OOB pairing Dimensions: 15.0 x 10.2 x 1.9 mm UBX-19033353 - R10 Functional description Page 5 of 40 BMD-340 - Data sheet 1.2 Applications • • • • • • • • • • • • • • Climate control Lighting products Safety and security Home appliances Access control Internet of Things Home Health Care Advanced Remote Controls Smart Energy Management Low-Power Sensor Networks Interactive Entertainment Devices Environmental Monitoring Hotel Automation Office Automation 1.3 Block diagram Figure 1: Block diagram of BMD-340 UBX-19033353 - R10 Functional description Page 6 of 40 BMD-340 - Data sheet 1.4 Product specifications Detail Description Bluetooth Bluetooth version Bluetooth 5 Low Energy, Concurrent Central & Peripheral (S140), LE Coded PHY (Long Range), LE 2M PHY, LE 1M PHY, Advertising Extensions, CSA #2, Bluetooth mesh Security AES-128, Arm® Cryptocell accelerated LE connections Concurrent central, observer, peripheral, and broadcaster roles with up to twenty concurrent connections along with one Observer and one Broadcaster (S140) IEEE 802.15.4 Thread stack OpenThread, Thread 1.1 Thread security AES-128, Arm® Cryptocell accelerated Zigbee stack Zigbee Compliant Platform Radio Frequency 2.360 GHz to 2.500 GHz Modulations GFSK at 1 Mbps and 2 Mbps, QPSK at 250 Kbps Transmit power +8 dBm maximum Receiver sensitivity -96 dBm (Bluetooth low energy mode) Antenna Integrated PCB (-1dBi max gain) Current consumption TX only @ +8 dBm, 0 dBm @ 3V, DCDC enabled 14.8 mA, 4.8 mA TX only @ +8 dBm, 0 dBm 32.7 mA, 10.6 mA RX only @ 1 Mbps @ 3V, DCDC enabled 4.6 mA RX only @ 1 Mbps 9.9 mA CPU @ 64 MHz from flash, from RAM 6.3 mA, 5.2 mA CPU @ 64 MHz from flash, from RAM @ 3V, DCDC enabled 3.3 mA, 2.8 mA System Off, On (Supply on VCC), no RAM retention 0.4 µA, 0.97 µA System Off, On (Supply on VCC), full 256 KB RAM retention 1.86 µA, 2.35 µA Dimensions BMD-340 Length: 15.0 mm ± 0.3 mm Width: 10.2 mm ± 0.3 mm Height: 1.9 mm ± 0.1 mm Hardware Interfaces SPI Master/Slave x 4 Quad SPI x 1 UART x 2 Two-Wire Master/Slave (I2C) x 2 GPIO x 48 I2S x1 PWM x 16 (4 blocks x 4-channels each) PDM x 1 USB 2.0 x 1 Analog input x 8 Power supply VCC: 1.7 V to 3.6 V, 1.75 V required to start DCDC VCCH: 2.5 V to 5.5 V VBUS: 4.35 V to 5.5 V (For USB operation) Temperature range -40 °C to +85 °C UBX-19033353 - R10 Functional description Page 7 of 40 BMD-340 - Data sheet Detail Description Certifications USA (FCC) FCC part 15.247 modular certification FCC ID: 2AA9B10 Canada (ISED) Innovation, Science and Economic Development Canada RSS247 modular certification IC: 12208A-10 Europe (CE) EN 60950-1: A2:2013 3.1 (a): Health and Safety of the User EN 301 489-1 V2.1.1 & 3.1 (b): Electromagnetic Compatibility EN 301 489-17 V3.1.1 EN 300 328 V2.1.1 3.2: Effective use of spectrum allocated Australia / New Zealand (RCM) AS/NZS 4268:2017, Radio equipment and systems – Short range devices Bluetooth BMD-340 RF-PHY Component (Tested) – DID: D040773; QDID: 95452 Radio chip Nordic semiconductor nRF52840 Additional details: nRF52840 Product Specification Software Development Kit Table 1: Product specifications UBX-19033353 - R10 Functional description Page 8 of 40 BMD-340 - Data sheet 2 Pin definition 2.1 Pin assignment Figure 2: BMD-340 Pin assignment (Top view) No. Name I/O Description nRF52 pin Remarks 1 GND Power Electrical Ground 2 GND Power Electrical Ground 3 GND Power Electrical Ground 4 GND Power Electrical Ground 5 GND Power Electrical Ground 6 P0.25 I/O GPIO P0.25 7 P0.26 I/O GPIO P0.26 8 P0.27 I/O GPIO P0.27 9 P0.28 I/O GPIO/AIN4 P0.28 Standard drive, low frequency I/O only (
