RN4678 2.0 APPLICATION INFORMATION 2.1 Module Configuration the RN4678, the CTS (RN4678 input pin) must be pulled high. The RN4678 pulls the RTS pin (output pin) low to indicate that it can accept data. 2.3 For the I/O pins, P2_0, P2_4 and EAN, place the RN4678 into Operating mode. Each of these pins have internal pull-up and allow configuration settings and firmware to be updated from UART. Table 2-1 provides system configuration details. 2.2 The GPIO pins of the RN4678 module can be configured to different functions using the ASCII command interface. Table 2-2 shows the various pins in the RN4678 module that are available for configuration and their default configuration settings. Table 2-3 provides details on each of the functions available. Flow Control Flow control is enabled by default on the RN4678 module. With the flow control enabled, the RTS and CTS lines need to be connected to the corresponding lines for the module to operate. To pause data flow from TABLE 2-1: Control and Indication I/O Pins SYSTEM CONFIGURATION SETTINGS P2_0 P2_4 EAN Low Low High Write FLASH Low High Low Write EEPROM and Test mode High High Low Normal Operational/Application mode TABLE 2-2: Operational Mode CONTROL AND INDICATION I/O PIN ASSIGNMENTS PIN Symbol Default Configuration P0_0 UART_RTS(1,2) P0_5 N/C P1_7 UART_CTS(1,2) P3_1 INQUIRY CONTROL P3_2 LINK_DROP_CONTROL (DISCONNECT) P3_3 UART_RX_IND P3_4 PAIRING_KEY P3_7 LOW_BATTERY_IND Note 1: The RTS pin can only be assigned to P0_0 and the CTS pin can only be assigned to P1_7. 2: The RTS and CTS pins can be configured as GPIOs if flow control is disabled. TABLE 2-3: CONFIGURABLE FUNCTIONS AND DESCRIPTIONS Function Name Description Low Battery Indication Pin output goes low when the battery level is below a specified level. Default battery low indication voltage level is 3.4V RSSI Indication Use this pin to indicate the quality of the link based on the RSSI level. If the RSSI level is lower than the specified values, then the RSSI indication pin goes low. Link Drop Control Use this pin to force the module to drop the current BLE link with a peer device. Pulling the Link Drop pin low forces to disconnect. The pin must be pulled low for at least 10 ms. 2016-2019 Microchip Technology Inc. DS50002519D-page 7 RN4678 Function Name Description UART RX Indication Use this pin to enable communication with the UART when the module is in Low-Power mode. When not in Low-Power mode, the module runs on a 16 MHz clock. If Low-Power mode is enabled on the module by using command SO,1, the module runs on a 32 kHz clock thus reducing power consumption. However, in Low-Power mode, the host MCU cannot communicate with the module via the UART since the UART is not operational. If the user intends to provide data or commands via UART in the Low-Power mode, then the UART_RX_IND pin must be pulled low and the user needs to wait for at least five milliseconds before sending the data. Pulling the UART_RX_IND pin low allows the module to operate the 16 MHz clock and to enable UART. Pairing Key Use this pin to force the module to enter Standby mode. The pin must be pulled down for at least 160 ms. Inquiry Control This pin forces the module enter Inquiry mode (BT Classic). The pin must be pulled low for at least 240 ms for the device to enter Inquiry mode. Profile_IND This pin is used to indicate whether current connection is in BR/EDR (BT Classic), or in Bluetooth Low Energy (BLE). If the Profile_IND pin is high, then the current connection is BR/EDR connection. If low, then the current connection is a BLE connection. This pin is valid only for Link State. 2.4 Power Tree Figure 2-1 illustrates the power tree diagram of the RN4678.

RN4678 2.5 Software Button (SW_BTN) Figure 2-2 through Figure 2-4 show the timing diagrams for the RN4678 with regard to the SW_BTN and the other relevant pins in different states of the module. The Software Button (SW_BT) pin powers the main sections of the module into operation. If the SW_BTN pin is low, the module is turned OFF. After turning the module ON via the SW_BTN, the host MCU must wait for specific time before sending the first command. The timing diagrams for the SW_BTN, other related pins, and the time delay are required before the host MCU sends the first command. Note: By default, the SW_BTN functionality is disabled and it can be enabled using the Host MCU commands. Refer to the RN4678 Command Reference User Guide (DS50002506) for more details.

RN4678 6.0 REFLOW PROFILE The RN4678 is highly recommended to be assembled using a standard lead-free reflow profile, IPC/JEDEC J-STD-020. The RN4678 can be soldered to the host PCB by using the standard leaded and lead-free solder reflow profile. To avoid damage to the module, follow these recommendations: * Follow solder reflow recommendations provided in Microchip Technology Application Note AN233 Solder Reflow Recommendation (DS00233). * Refer to the solder paste data sheet for specific reflow profile recommendations. * Do not exceed the peak temperature (TP) of 250C. * Use no-clean flux solder paste. * Do not wash as moisture can be trapped under the shield. * Use only one flow. If the PCB requires multiple flows, apply the module on the final flow.

RN4678 7.0 MODULE PLACEMENT For a Bluetooth wireless product, the antenna placement affects the performance of the whole system. The antenna requires free space to radiate the RF signal and it cannot be surrounded by the ground plane. Microchip recommends that the areas underneath the antenna on the host PCB must not contain copper on top, inner or bottom layer. Figure 7-1 illustrates an example of good and poor antenna placement on a host PCB with ground plane. The ground plane can be extended beyond the minimum recommended as required for the main PCB EMC noise reduction. For the best range performance, keep all external metal away from the ceramic chip antenna, that is minimum 15 mm away.

RN4678 9.0 REGULATORY APPROVAL This section outlines the regulatory information for the RN4678 module for the following countries: * * * * * * * United States Canada Europe Japan Korea Taiwan Other Regulatory Jurisdictions 9.1 United States The RN4678 module has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C "Intentional Radiators" singlemodular approval in accordance with Part 15.212 Modular Transmitter approval. Single-modular transmitter approval is defined as a complete RF transmission sub-assembly, designed to be incorporated into another device, that must demonstrate compliance with FCC rules and policies independent of any host. A transmitter with a modular grant can be installed in different end-use products (referred to as a host, host product, or host device) by the grantee or other equipment manufacturer, then the host product may not require additional testing or equipment authorization for the transmitter function provided by that specific module or limited module device. The user must comply with all of the instructions provided by the Grantee, which indicate installation and/or operating conditions necessary for compliance. A host product itself is required to comply with all other applicable FCC equipment authorization regulations, requirements, and equipment functions that are not associated with the transmitter module portion. For example, compliance must be demonstrated: to regulations for other transmitter components within a host product; to requirements for unintentional radiators (Part 15 Subpart B), such as digital devices, computer peripherals, radio receivers, etc.; and to additional authorization requirements for the non-transmitter functions on the transmitter module (i.e., Verification or Declaration of Conformity) as appropriate (e.g., Bluetooth and Wi-Fi transmitter modules may also contain digital logic functions). 9.1.1 LABELING AND USER INFORMATION REQUIREMENTS The RN4678 module has been labeled with its own FCC ID number, and if the FCC ID is not visible when the module is installed inside another device, then the outside of the finished product into which the module is installed must also display a label referring to the enclosed module.
