BM70/BM71 FIGURE 1-5: BM70 EMBEDDED APPLICATION EXAMPLE – Button Cell Battery 1.8 Mounting Details BM70BLES1FC2 The BM70BLES1FC2 physical dimensions are shown in Figure 1-6, recommended host PCB footprint in Figure 1-7, and mounting suggestion in Figure 1-8. There should not be top copper layer near the test pin area shown in Figure 1-7. When laying out the host PCB, the areas under the antenna should not contain any top, inner layer, or bottom copper as shown in Figure 1-8. A low-impedance ground plane will ensure best radio performance (best range, lowest noise). Figure 1-8 shows a minimum ground plane area to the left and right of the module for best antenna performance. The ground plane can be extended beyond the minimum recommended as need for host PCB EMC noise reduction. For best range performance, keep all external metal away from the ceramic chip antenna at least 30 mm. BM70BLE01FC2 The BM70BLE01FC2 physical dimensions are shown in Figure 1-9, recommended host PCB footprint in Figure 1-10, and mounting suggestion in Figure 1-11. It is highly recommended to layout the host PCB as suggested in Figure 1-11. A low-impedance ground plane will ensure best radio performance (best range, lowest noise). Pin 30 (BT_RF) is a 50 ohm connection to an external antenna connector, PCB trace antenna, or component (ceramic chip) antenna through a host PCB 50 ohm micro-strip trace. This trace can be extended to include passive parts for antenna attenuation padding, impedance matching, or to provide test posts. It is recommended that the micro-strip trace be as short as possible for minimum loss and best impedance matching. If the micro-strip trace is longer, it should be a 50 ohm impedance. Figure 1-11 shows an example connection to U.FL connector. 2015 Microchip Technology Inc. Advance Information Page 11

BM70/BM71 3.3 Europe The BM70BLES1FC2 module is an R&TTE Directive assessed radio module that is CE marked and has been manufactured and tested with the intention of being integrated into a final product. The BM70 module has been tested to R&TTE Directive 1999/5/EC Essential Requirements for Health and Safety (Article (3.1(a)), Electromagnetic Compatibility (EMC) (Article 3.1(b)), and Radio (Article 3.2) and are summarized in Table 3‐1: European Compliance Testing. A Notified Body Opinion has also been issued. All test reports are available on the BM70 product web page at http://www.microchip.com/bm70. The R&TTE Compliance Association provides guidance on modular devices in document Technical Guidance Note 01 available at http://www.rtteca.com/html/download_area.htm. Note: To maintain conformance to the testing listed in Table 3‐1: European Compliance Testing, the module shall be installed in accordance with the installation instructions in this data sheet and shall not be modified. When integrating a radio module into a completed product the integrator becomes the manufacturer of the final product and is therefore responsible for demonstrating compliance of the final product with the essential requirements of the R&TTE Directive. 3.1.3 LABELING AND USER INFORMATION REQUIREMENTS The label on the final product which contains the BM70 module must follow CE marking requirements. The R&TTE Compliance Association Technical Guidance Note 01 provides guidance on final product CE marking. 3.1.4 ANTENNA REQUIREMENTS From R&TTE Compliance Association document Technical Guidance Note 01: Provided the integrator installing an assessed radio module with an integral or specific antenna and installed in conformance with the radio module manufacturer’s installation instructions requires no further evaluation under Article 3.2 of the R&TTE Directive and does not require further involvement of an R&TTE Directive Notified Body for the final product. [Section 2.2.4] The European Compliance Testing listed in Table 3‐1 was performed using the integral ceramic chip antenna.

A document that can be used as a starting point in understanding the use of Short Range Devices (SRD) in Europe is the European Radio Communications Committee (ERC) Recommendation 70‐03 E, which can be downloaded from the European Radio Communications Office (ERO) at: http://www.ero.dk/. Additional helpful web sites are: • Radio and Telecommunications Terminal Equipment (R&TTE): http://ec.europa.eu/enterprise/rtte/index_en.htm • European Conference of Postal and Telecommunications Administrations (CEPT): http://www.cept.org • European Telecommunications Standards Institute (ETSI): http://www.etsi.org • European Radio Communications Office (ERO): http://www.ero.dk • The Radio and Telecommunications Terminal Equipment Compliance Association (R&TTE CA): http://www.rtteca.com/ 3.2 Australia The Australia radio regulations do not provide a modular approval policy similar to the United States (FCC) and Canada (IC). However, BM70 module RF transmitter test reports can be used in part to demonstrate compliance in accordance with ACMA Radio communications “Short Range Devices” Standard 2004 (The Short Range Devices standard calls up the AS/NZS 4268:2008 industry standard). The BM70 module test reports can be used as part of the product certification and compliance folder. For more information on the RF transmitter test reports, contact Microchip Technology Australia sales office. To meet overall Australian final product compliance, the developer must construct a compliance folder containing all relevant compliance test reports e.g. RF, EMC, electrical safety and DoC (Declaration of Conformity) etc. It is the responsibility of the integrator to know what is required in the compliance folder for ACMA compliance. All test reports are available on the BM70 product web page at http://www.microchip.com.
