FSC‐BT646 Datasheet 4.6 Serial Interfaces 4.6.1 UART FSC‐BT646 provides one channels of Universal Asynchronous Receiver/Transmitters (UART)(Full‐duplex asynchronous communications). The UART Controller performs a serial‐to‐parallel conversion on data received from the peripheral and a parallel‐to‐serial conversion on data transmitted from the CPU. This is a standard UART interface for communicating with other serial devices.

FSC‐BT646 Datasheet 8.2 Host PCB Land Pattern and Antenna Keep‐out for FSC‐BT646 Please check the picture below for Pad Structure and Keep Out Area: Figure 7: Host PCB‐Top View 9. 9.1 HARDWARE INTEGRATION SUGGESTIONS Soldering Recommendations FSC‐BT646 is compatible with industrial standard reflow profile for Pb‐free solders. The reflow profile used is dependent on the thermal mass of the entire populated PCB, heat transfer efficiency of the oven and particular type of solder paste used.
FSC‐BT646 Datasheet 9.2 Layout Guidelines(Internal Antenna) It is strongly recommended to use good layout practices to ensure proper operation of the module. Placing copper or any metal near antenna deteriorates its operation by having effect on the matching properties. Metal shield around the antenna will prevent the radiation and thus metal case should not be used with the module.
FSC‐BT646 Datasheet As indicated in picture below, RF critical circuits of the module should be clearly separated from any digital circuits on the system board. All RF circuits in the module are close to the antenna port. The module, then, should be placed in this way that module digital part towards your digital section of the system PCB. Non enmitting circuits Non enmitting circuits RF_IN Digital Part Digital & Analog Circuits PCB Figure 9: Placement the Module on a System Board 9.3.
FSC‐BT646 Datasheet Figure 11: Recommended Trace Connects Antenna and the Module Routing of the RF‐connection underneath the module should be avoided. The distance of the micro strip line to the ground plane on the bottom side of the receiver is very small and has huge tolerances. Therefore, the impedance of this part of the trace cannot be controlled. Use as many vias as possible to connect the ground planes. 10. 10.

FSC‐BT646 Datasheet 11. Certifications FCC ID: 2AMWOFSC‐BT646 (OEM) Integrator has to assure compliance of the entire end‐product incl. the integrated RF Module. For 15 B (§15.107 and if applicable §15.107) compliance, the host manufacturer is required to show compliance with 15 while the module is installed and operating. Furthermore the module should be transmitting and the evaluation should confirm that the module's intentional emissions (15C) are compliant (fundamental / out‐of‐band).
Module statement The single-modular transmitter is a self-contained, physically delineated, component for which compliance can be demonstrated independent of the host operating conditions, and which complies with all eight requirements of § 15.212(a)(1) as summarized below. 1) The radio elements have the radio frequency circuitry shielded. 2) The module has buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal.
Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 2.2 2.3 2.4 - List of applicable FCC rules FCC Part 15.247 - Summarize the specific operational use conditions This transmitter/module and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter. This information also extends to the host manufacturer’s instruction manual. 2.
2.9 Information on test modes and additional testing requirements Information on test modes: The host manufacturer can use software for access to the test modes. Connected to the device through the serial port of the host product and control the module. If it does not work, then the host product manufacturer should coordinate with the module manufacturer for access to test mode software. The following provides guidance to host product when installing this module on how they may verify the end product: A.
