FLC-BTM403 Datasheet 4. Physical Interfaces 4.1 Power Supply The transient response of the regulator is important. If the power rails of the module are supplied from an external voltage source, the transient response of any regulator used should be 20μs or less. It is essential that the power rail recovers quickly. 4.2 Reset The module may be reset from several sources: RESET pin, power-on reset, a UART break character or via a software configured watchdog timer.
FLC-BTM403 Datasheet Note: Pull-up (PU) and pull-down (PD) default to weak values unless specified otherwise. 4.3 Digital Audio Interfaces The module has offered PCM digital audio interface. PCM is a standard method used to digitize audio (particularly voice) for transmission over digital communication channels. Through its PCM interface, the module has hardware support for continual transmission and reception of PCM data, thus reducing processor overhead for applications.
FLC-BTM403 Datasheet Figure 3: Configured PCM as a Master When PCM is configured as the slave, the module accepts PCM_CLK rates up to 2048kHz. Figure 4: Configured PCM as a Slave 4.3.2 Long Frame Sync Long Frame Sync is the name given to a clocking format that controls the transfer of PCM data words or samples. In Long Frame Sync, the rising edge of PCM_SYNC indicates the start of the PCM word. When the module is configured as PCM master, generating PCM_SYNC and PCM_CLK, then PCM_SYNC is 8-bits long.
FLC-BTM403 Datasheet Figure 5: Long Frame Sync (Shown with 8-bit Companded Sample) 4.3.3 Short Frame Sync In Short Frame Sync, the falling edge of PCM_SYNC indicates the start of the PCM word. PCM_SYNC is always one clock cycle long. Figure 6: Short Frame Sync (Shown with 16-bit Sample) As with Long Frame Sync, the module samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising edge.
FLC-BTM403 Datasheet Figure 7: Multi-Slot Operation with Two Slots and 8-bit Companded Samples 4.3.5 GCI Interface The module is compatible with the General Circuit Interface (GCI), a standard synchronous 2B+D ISDN timing interface. The two 64Kbps B channels can be accessed when this mode is configured. Figure 8: GCI Interface The start of a frame is indicated by the rising edge of PCM_SYNC and runs at 8kHz. With the module in slave mode, the frequency of PCM_CLK can be up to 4.096MHz. 4.3.
FLC-BTM403 Datasheet Figure 9: 16-Bit Slot Length and Sample Formats 4.3.7 Additional Features The module has a mute facility that forces PCM_OUT to be 0. In master mode, PCM_SYNC may also be forced to 0 while keeping PCM_CLK running which some CODECS use to control power down. 4.3.8 PCM Timing Information Symbol Parameter Min Typical Max Unit - kHz 128 fmclk PCL_CLK Frequency 4MHz DDS generation.

The interface is formed using software to drive these lines. It is suited only to relatively slow functions such as driving a LCD, Keyboard, scanner or EEPROM. In the case, PIO lines need to be pulled up through 2.2Kohm resistors. VDD Figure 16: Example EEPROM Connection with I2C Interface 4.7.

(2) This device must accept any interference received, including interference that may cause undesired operation. 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
FLC-BTM403 Datasheet The packaging of host system that uses BTM403 should display a label indicating the information as follows: Contains FCC ID: P4IBTM403 Model: FLC-BTM403IQ2A (Series models: FLC-BTM403IQ2B/ FLC-BTM403IQ2C/ FLC-BTM403VQ2A/ FLC-BTM403VQ2B/FLC-BTM403VQ2C) QDID: Any similar wording that expresses the same meaning may also be used. 11.4 FLC-BTM403 Antenna Statement Note: In this section, “A”, “B” and “C” in “BTM403A”, “BTM403B” and “BTM403C” refer to Product Revision.
FLC-BTM403 Datasheet The following figure shows the Radiation Patterns of the antenna in BTM403A and BTM403C.
FLC-BTM403 Datasheet 11.4.2 BTM403B There is no built-in antenna in BTM403B. BTM403B is integrated with a UFL connector to make it simple for designers to add an external antenna into the module. In order to make the product compliant with the FCC standard, the applicable antennas which designers choose should be similar to the antenna in BTM403A and BTM403C in specifications and radiation patterns. And the gain should be less than the peak gain of the antenna in BTM403A and BTM403C.
