The GPIOs are configurable, and the connection depends on the user’s application circuit. It is recommended to use an external Reset IC in all applications. An example of using this circuit with the MCP111-195 is illustrated in Figure 2-1, Figure 2-3, Figure 2-5, and Figure 2-7. This Reset IC prevents the Flash data corruption, when VBAT drops below 1.9V (this includes brown-out, power-down, and power-up conditions). The RF antenna impedance matching circuit in Figure 2-3 and Figure 2-5 require users to implement by the selected antenna specification. For battery-powered applications, it is recommended to use the following external circuits as illustrated in Figure 2-2, Figure 2-4, Figure 2-6, and Figure 2-8. The first circuit (left side) ensures that the LED indicator is bright enough in applications with VBAT > 3.0V. The second circuit (right side) provides protection from battery voltage reverse connection. If a fixed voltage source is applied to VBAT (e.g. 3.3V), the soft start output is necessary to prevent the inrush voltage over 3.6V to damage the Flash. ## **FIGURE 2-1: BM70BLES1FC2 REFERENCE CIRCUIT** DS60001372J-Page 13  2015-2019 Microchip Technology Inc. **BM70/71** ## **FIGURE 2-2: BM70BLES1FC2 REFERENCE CIRCUIT** ## **FIGURE 2-3: BM70BLE01FC2 REFERENCE CIRCUIT** DS60001372J-Page 14  2015-2019 Microchip Technology Inc. **BM70/71** ## **FIGURE 2-4:** ## **BM70BLE01FC2 REFERENCE CIRCUIT** ## **FIGURE 2-5: BM71BLE01FC2 REFERENCE CIRCUIT** - **Note 1:** Place the capacitor C3 as close as possible to the module.

UART uses Host Control Interface (HCI) to share the communication among the Host MCU and BM70/71 module. The interface also illustrates the power scheme using a 3.3V Low Drop Out (LDO) regulator that supplies 3.3V to the BM70/71 (BAT_IN) and MCU VDD. This power scheme ensures that the BM70/71 module and MCU I/O voltages are compatible. ## **FIGURE 2-10: BM70 MODULE TO MCU INTERFACE** **Note 1:** Ensure that VBAT(=I/O Voltage) and MCU VDD voltages are compatible. - **2:** Control and indication ports are configurable.

It also illustrates an application using a coin cell battery at VBAT input. For the BM71 module, a 10 μF capacitor (X5R/X7R) is applied to the BAT_IN pin. Only on the BM71 module, the BK_IN pin of the module must be connected to the BAT_IN pin. ## **FIGURE 2-14: BM71 MODULE TYPICAL HOSTED CONFIGURATION** **Note 1:** Hardware functions can include ADC and PWM.

However, the average current consumption is only around 230 μA while advertising at an interval of approximately 100 ms, see Figure 5-2. This is due to the “Reduced Current Consumption” Low Power mode being enabled (configuration parameter - UART_RX_IND). Reducing the current draw to approximately 60 μA, while not actively transmitting the advertisings packets, refer to the “ _BM70/71 Bluetooth[®] Low Energy Module User’s Guide”_ (DS50002542) for more details. The overall average current consumption is measured with a 3.3V VBAT input, and is affected by the way the IS1870/71 IC on the BM70/71 module has been configured to operate. A low average current value can be achieved by choosing the minimum settings for the advertising interval and connection interval, which meet the data throughput requirements of the intended application. The lower or less frequent the interval time periods, the lower the overall average current to be drawn. ## **FIGURE 5-1: TX/RX PEAK CURRENT CONSUMPTION OF AN ADVERTISING EVENT** DS60001372J-Page 40  2015-2019 Microchip Technology Inc. **BM70/71** Figure 5-2 illustrates the oscilloscope screen, captured when the auto operation and Low Power mode is active on the BM70/71 module.
