Reference Circuit This chapter shows a different combination of reference circuits. Before getting started, please read below notes carefully because it is applied to all the reference circuits. 32MHz crystal and RF (VDD) DC/DC inductor (Reg1) are already inside the module. Module is pre-programmed with Raytac testing code. Default is using DC-DC mode and need to add external 32.768khz to work. You can use DC-DC mode without adding external 32.768khz, they are NOT related events. When using internal 32.768khz RC oscillator, please remove X2 / C12 / C13. Recommended L4 spec: 10H, 0603 Chip Inductor, IDC, min = 80mA, 20%. When NOT using NFC, please remove NFC1 / C19 / C21. 36 8.1. Reg0 DC/DC Enabled Recommend using when the highest input voltage is equal or greater than 3.6V. Supply power from VCC2 (VDDH). Please check "Nordic PCN111 Product Change Notification v1.0" for more details about this reference circuit. 37 8.2. Reg0 LDO Mode Recommend using when the highest input voltage is equal or greater than 3.6V. Supply power from VCC2 (VDDH). 38 8.3. Reg0 DC/DC and LDO Mode Disabled Recommend using when the highest input voltage is less than 3.6V. 39 8.4. USB Disabled This circuit only focuses on USB disabled.

Notes and Cautions Module is not designed to last for a lifetime. Like general products, it is expected to be worn out after continuous usage through the years. To assure that product will perform better and last longer, please make sure you: Follow the guidelines of this document while designing circuit/end-product. Any discrepancy of core Bluetooth technology and technical specification of IC should refer to definition of Bluetooth Organization and Nordic Semiconductor as final reference. Do not supply voltage that is not within range of specification. Eliminate static electricity at any cost when working with the module as it may cause damage. It is highly recommended adding anti-ESD components to circuit design to prevent damage from real-life ESD events. Anti-ESD methods can be also applied in mechanical design. Do not expose modules under direct sunlight for long duration. Modules should be kept away from humid and salty air conditions, and any corrosive gasses or substances. Store it within -40 to +125 before and after installation. Avoid any physical shock, intense stress to the module or its surface. Do not wash the module. No-Clean Paste is used in production. Washing it will oxidize the metal shield and have chemistry reaction with No-Clean Paste. Functions of the module are not guaranteed if it has been washed. The module is not suitable for life support device or system and not allowed to be used in destructive device or systems in any direct or indirect ways. The customer agrees to indemnify Raytac for any losses when applying modules in applications such as the ones described above. 55 11.
