However, it is good design practice to add additional bulk capacitance as required for your application, i.e. those with heavy GPIO usage and/or current draw. Note 2: These pins are in close proximity to the nRF52 radio power supply and antenna pins. Radio performance parameters, such as sensitivity, may be affected by high frequency digital I/O with large sink/source current on these pins. Nordic recommends using only low frequency, low-drive functions when possible. Note 3: In HV mode, VCC acts as a regulated supply that can power other external devices. The voltage output of VCC can be configured in software but is limited to no more than VCCH-0.3V. In System Off mode VCC can supply no more than 1mA. Table 2 – BMD-345 Pin Descriptions
BMD-345 V1.0 CONFIDENTIAL Page 8 of 20 4.2 Peripheral Pins The BMD-345 features a pin muxing system that allows most internal peripherals, such as UART and SPI, to be used on any GPIO pin. This freedom in pin choice enables better optimization of designs and PCB layout. Note that only one peripheral signal can be muxed to a GPIO pin at a time. Some functions are restricted to certain pins due to additional internal circuitry required by the interface. These include: Trace signals, analog inputs, XTAL signals, USB signals, SWD interface, and reset. See Table 3 below for details: Peripheral Signal Pin Options UART0, UART1 All P0.00-P0.31, P1.00-P1.15 I2C0, I2C1 SPI0, SPI1, SPI2, SPI3 I2S0 QSPI0 PWM0, PWM1, PWM2, PWM3 PDN0 ADC, COMP, LPCOMP All P0.02-P0.05, P0.28-P0.31 (AIN0-AIN7) NFC NFC1 P0.09 NFC2 P0.10 Reset RESET̅̅̅̅̅̅̅̅ P0.18 Trace TRACECLK P0.07 SWO/TRACEDATA[0] P1.00 TRACEDATA[1] P0.12 TRACEDATA[2] P0.11 TRACEDATA[3] P1.09 SWD SWD Clock SWCLK SWD IO SWDIO 32.768kHz Crystal XTAL1 P0.00 XTAL2 P0.01 USB USB Data + USB-D+ USB Data - USB-D- Table 3 – Peripheral Pin Options Note: Some peripherals on the BMD-345 share the same memory location for their registers. This means that only one of these peripherals can be used at a time. It is possible to switch between peripherals that share the same register location by clearing and reinitializing the associated configuration registers. See the Nordic Semiconductor nRF52840 Product Specification for details.

BMD-345 V1.0 CONFIDENTIAL Page 10 of 20 5.3 Power Configuration 5.3.1 USB Power The BMD-345 USB PHY is powered by a dedicated, internal LDO regulator that is fed by the VBUS pin (66). This means that applying power to only the VBUS pin will not power the rest of the module. In order for the USB PHY to operate, VBUS must be externally powered. 5.4 General Purpose I/O The general purpose I/O is organized as two ports enabling access and control of the 48 available GPIO pins. The first port allows access of P0.00 to P0.31, similar to the one port available on the BMD-301. The second port, new to the BMD-345, allows access to P1.00 to P1.15. Each GPIO can be accessed individually with the following user configurable features: • Input/output direction • Output drive strength • Internal pull-up and pull-down resistors • Wake-up from high or low level triggers on all pins • Trigger interrupt on all pins • All pins can be used by the PPI task/event system; the maximum number of pins that can be interfaced through the PPI at the same time is limited by the number of GPIOTE channels • All pins can be individually configured to carry serial interface or quadrature demodulator signals Symbol Parameter Min.

In order to utilize P0.18 as a hardware reset, the UICR registers PSELRESET[0] and PSELRESET[1] must be set alike, to the value of 0x7FFFFFD2. When P0.18 is programmed as RESET̅̅̅̅̅̅̅̅, the internal pull-up is automatically enabled. Rigado and Nordic example applications and development kits program P0.18 as RESET̅̅̅̅̅̅̅̅. 5.6 Debug & Programming The BMD-345 supports the two pin Serial Wire Debug (SWD) interface and offers flexible and powerful mechanisms for non-intrusive debugging of program code. Breakpoints, single stepping, and instruction trace capture of code execution flow are part of this support. The BMD-345 also supports ETM and ITM trace. Trace data from the ETM and the ITM is sent to an external debugger via a 4-bit wide parallel trace port. In addition to parallel trace, the TPIU supports serial trace via the Serial Wire Output (SWO) trace protocol.
BMD-345 V1.0 CONFIDENTIAL Page 11 of 20 5.7 Clocks The BMD-345 requires two clocks, a high frequency clock and a low frequency clock. The high frequency clock is provided on-module by a high-accuracy 32-MHz crystal as required by the nRF52840 for radio operation. The low frequency clock can be provided internally by an RC oscillator or synthesized from the fast clock; or externally by a 32.768 kHz crystal. An external crystal provides the lowest power consumption and greatest accuracy. Using the internal RC oscillator with calibration provides acceptable performance for BLE applications at a reduced cost and slight increase in power consumption. Note: the ANT protocol requires the use of an external crystal. 32.768 kHz Crystal (LFXO) Symbol Parameter Typ. Max.

Actual tolerance depends on the crystal used. Table 10 – 32.768 kHz Oscillator
BMD-345 V1.0 CONFIDENTIAL Page 12 of 20 5.8 MAC Address Info The BMD-345 modules comes preprogrammed with a unique MAC address from the factory. The MAC address is also printed on a 2D barcode on the top of the module. Figure 3 – BMD-345 MAC Address on Label The 6-byte BLE Radio MAC address is stored in the nRF52840 UICR at NRF_UICR_BASE+0x80 LSB first. Please read the MAC Address Provisioning application note if you are not using the built in bootloader to avoid erasing/overwriting the MAC address during programming. Important: If full memory protection is enabled, the UICR cannot be read via the SWD interface. If performing a full-erase, the MAC can then only be recovered from the 2D barcode and human-readable text. UICR Register: NRF_UICR + 0x80 (0x10001080): MAC_Addr [0] (0xZZ) NRF_UICR + 0x81 (0x10001081): MAC_Addr [1] (0xYY) NRF_UICR + 0x82 (0x10001082): MAC_Addr [2] (0xXX) NRF_UICR + 0x83 (0x10001083): MAC_Addr [3] (0x93) NRF_UICR + 0x84 (0x10001084): MAC_Addr [4] (0x54) NRF_UICR + 0x85 (0x10001085): MAC_Addr [5] (0x94)
