TCM3901 TCM3901_SPECIFICATION May 30, 2017 Bluetooth V4.1 Class2 Module STARTUP TIMING 7-10 7 Startup Timing The TCM3901 startup and firmware boot is held off while the RESET pin is asserted. The TCM3901 has an integrated power-on reset circuit which completely resets all circuits to a known power on state. This action can also be driven by RST_N signal, which can be used to externally control the device, forcing it into a power-on reset state. Note:  VBAT should be up before or at the same time as VDDIO, BT_REG_ON.  RST_N signal input is an active-low signal. This signal must be driven high or low (not left floating).  The TCM3901 requires an external pull-up resistor on the RST_N input. Figure 7.1 Startup Timing from RST_N
TCM3901 TCM3901_ SPECIFICATION May 30, 2017 Bluetooth V4.1 Class2 Module INTERFACE DESCRIPTION 8-11 8 Interface Description 8.1 UART The UART physical interface is a standard, 4-wire(RX, TX, RTS, CTS) with adjustable baud rates from 9600 bps to 4.0 Mbps. The interface features an automatic baud rate detection capability that returns a baud rate selection. Alternatively, the baud rate can be selected via a vendor-specific UART HCI commend. The interface supports Bluetooth UART HCI specifications. The default baud rate is 115.2Kbaud. Figure 8.1 UART Interface Connection 8.2 PCM/I2S The TCM3901 PCM interface can connect to linear PCM codec devices in master or slave mode. In master mode, the device generates the PCM_BCLK and PCM_SYNC signals. In slave mode, these signals are provided by another master on the PCM interfaces as inputs to the device. The PCM interface supports the industry standard formats for I2S, left-justified or right-justified. The host can adjust the PCM interface configuration using vendor-specific HCI commands or it can be setup in the configuration file.

TCM3901 TCM3901_SPECIFICATION May 30, 2017 Bluetooth V4.1 Class2 Module INTERFACE DESCRIPTION 8-12 8.3 SECI The TCM3901 provides extensions and collaborative coexistence to the standard Bluetooth AFH for direct communication with WLAN devices. Collaborative coexistence enables WLAN and Bluetooth to operate simultaneously in a single device. The device supports industry-standard coexistence signaling, including 802.15.2, and supports WLAN solutions.  Enhanced coexistence data can be exchanged over SECI_IN and SECI_OUT  It supports generic UART communication between WLAN and Bluetooth devices.  Up to 48-bits of coexistence data can bel exchanged Figure 8.3 SECI Interface Connection TCM3901 SECI_OUT SECI_IN BT_STATUS SECI_IN SECI_OUT BT_STATUS WLAN device

Operation is subject to the following conditions: ( 1 )This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. FCC Caution Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. Important Note OEM Responsibilities to comply with FCC and Industry Canada Regulations The TCM3901 Module has been certified for integration into products only by OEM integrators under the following conditions: 1. The antenna(s) must be installed such that a minimum separation distance of 20cm is maintainedbetween the radiator (antenna) and all persons at all times. 2. The transmitter module must not be co-located or operating in conjunction with any other antenna ortransmitter. As long as the two conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). IMPORTANT NOTE: In the event that these conditions cannot be met (for certain configurations or co-location with another transmitter), then the FCC and Industry Canada authorizations are no longer considered valid and the FCC ID and IC Certification Number cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC and Industry Canada authorization. Label of the end product The final end product must be labeled in a visible area with the following " Contains FCC ID: 2ALS3-3901" and " Contains IC: 22661-3901". If the size of the end product is larger than 8x10cm, then the following FCC part 15.19 statement has to also be available on the label: This device complies with Part 15 of FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference and (2) this device must accept any interference received, including interference that may cause undesired operation. Canada Statement “This device complies with Industry Canada’s license-exempt RSSs. Operation is subject to the following two conditions: (1) This device may not cause interference; and (2) This device must accept any interference, including interference that may cause undesired operation of the device.” « Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. » Exposure to Radio Frequency Energy “To comply with FCC and Industry Canada RF radiation exposure limits for general population, the antenna(s) used for this transmitter must be installed such that a minimum separation distance of 20cm is maintained between the radiator (antenna) and all persons at all times and must not be co-located or operating in conjunction with any other antenna or transmitter.”
