BM70/71 2.0 APPLICATION INFORMATION 2.1 Reference Schematics Figure 2-1 through Figure 2-8 illustrate the BM70/71 module reference schematics for the various Stock Keeping Units (SKUs). 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). FIGURE 2-1: 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.

However, the average current consumption is only around 230 A 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 A, while not actively transmitting the FIGURE 5-1: DS60001372J-Page 40 advertisings packets, refer to the "BM70/71 Bluetooth(R) 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. TX/RX PEAK CURRENT CONSUMPTION OF AN ADVERTISING EVENT 2015-2019 Microchip Technology Inc.
