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.

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.

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

Product Marketing Name (PMN): Bluetooth module
FCC Statement
This device complies with Part 15 of the FCC rules. 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 maintained
between 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 or
transmitter.
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.”
