The TCM3903 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 BT_RST_N signal, which can be used to externally control the device, forcing it into a power-on reset state. Note:
VBAT and VDDIO should not rise 10%-90% faster than 200 microseconds. VBAT should be up before VDDIO. VDDIO should NOT be present first or be held high before VBAT is high. BT_RST_N signal input is an active-low signal. This signal must be driven high or low (not left floating). The TCM3903 requires an external pull-up or pull-down resistor on the BT_RST_N input.

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. HOST HOST_TX HOST_RX HOST_CTS HOST_RTS TCM3903 UART_RX UART_TX UART_RTS UART_CTS Figure 8.1 UART Interface Connection 8.2 PCM/I2S The TCM3903 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. Codec

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 TCM3903 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.).
