VDD 3.3 V supply voltage connection. i40e has an internal decoupling capacitor and LC filter to block high frequency disturbances. Thus external filtering is usually not needed. It is however recommended to leave an option for an external high Q 10pF decoupling capacitor in case EMC problems arise. RESETB The RESET pin is an active high reset and is internally filtered using the internal low frequency clock oscillator. A reset will be performed between 1.5 and 4.0ms following RESET being active. It is recommended that RESET be applied for a period greater than 5ms. BlueSoleil i40e has an internal reset circuitry, which keeps reset pin active until supply voltage has reached stability in the start up. See Figure 4below. This ensures that supply for the flash memory inside the i40e will reach stability before BC4 chip fetches instructions from it. Schematic of the reset circuitry is shown in figure 4. Rising supply voltage charges the capacitor, which will activate the reset of i40e. The capacitor discharges through 220k resistor, which eventually deactivates the reset. Time constant of the RC circuitry is set such that the supply voltage is safely stabilized before reset deactivates. Pull-up or pull-down resistor should not be connected to the reset pin to ensure proper star up of i40e. Figure 4 i40e Internal Reset Circuitry PIO0 PIO5, PIO9 PIO11 Programmable digital I/O lines.

Figure 5 i40e UART Interface Four signals are used to implement the UART function, as shown in Figure 5 above. When i40e is connected to another digital device, UART_RX and UART_TX transfer data between the two devices. The remaining two signals, UART_CTS and UART_RTS, can be used to implement RS232 hardware flow control where both are active low indicators. All UART connections are implemented using CMOS technology and have signaling levels of 0V and VDD. 15 / 37 BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet In order to communicate with the UART at its maximum data rate using a standard PC, an accelerated serial port adapter card is required for the PC. The possible UART settings are summarized in Table 8 below. Table 8 Possible UART Settings UART Parameters Possible Values Baud rate Minimum Maximum Flow control Parity Number of stop bits Bits per channel 1200 baud (2%Error) 9600 baud (1%Error) 3.0Mbaud (1%Error) RTS/CTS, none None, Odd, Even 1 or 2 8 The UART interface is capable of resetting i40e upon reception of a break signal. A Break is identified by a continuous logic low (0V) on the UART_RX terminal, as shown in Figure 5. If tBRK is longer than the value, defined by the PS Key PSKEY_HOST_IO_UART_RESET_TIMEOUT(0x1a4), a reset will occur. This feature allows a host to initialize the system to a known state. Also, i40e can emit a Break character that may be used to wake the Host. See Figure 6 below. Figure 6 Break Signal Since UART_RX terminal includes weak internal pull-down, it cant be left open unless disabling UART interface using PS_KEY settings. If UART is not disabled, a pull-up resistor has to be connected to UART_RX. UART interface requires external RS232 transceiver, which usually includes the required pull-up. 4.1.1 UART Configuration While RESET is Active The UART interface for i40e while the chip is being held in reset is tri-state. This will allow the user to daisy chain devices onto the physical UART bus. The constraint on this method is that any devices connected to this bus must tri-state when i40e reset is de-asserted and the firmware begins to run. 4.2 SPI Interface The synchronous serial port interface (SPI) is for interfacing with other digital devices. The SPI port can be used for system debugging. It can also be used for programming the Flash memory. SPI 16 / 37 BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet interface is connected using the MOSI, MISO, CSB and CLK pins. The module operates as a slave and thus MISO is an output of the module. MISO is not in high impedance state when CSB is pulled high. Instead, the module outputs 0 if the processor is running and 1 if it is stopped. 4.3 PCM Interface PCM is a standard method used to digitize audio (particularly voice) for transmission over digital communication channels. Through its PCM interface, i40e has hardware support for continual transmission and reception of PCM data, thus reducing processor overhead for wireless headset applications. i40e offers a bidirectional digital audio interface that routes directly into the baseband layer of the on-chip firmware. It does not pass through the HCI protocol layer. Hardware on i40e allows the data to be sent to and received from a SCO connection. Up to three SCO connections can be supported by the PCM interface at any one time. i40e can operate as the PCM interface master generating an output clock of 128, 256 or 512kHz.When configured as PCM interface slave, it can operate with an input clock up to 2048KHz. i40e is compatible with a variety of clock formats, including Long Frame Sync, Short Frame Sync and GCI timing environments. It supports 13-bit or 16-bit linear, 8-bit -law or A-law companded sample formats at 8ksamples/s and can receive and transmit on any selection of three of the first four slots following PCM_SYNC. The PCM configuration options are enabled by setting PSKEY_PCM_CONFIG32(0x1b3). 4.3.1 PCM Interface Master/Slave When configured as the Master of the PCM interface, i40e generates PCM_CLK and PCM_SYNC. See Figure 7 below. 17 / 37 BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet Figure 7 i40e as PCM Master When configured as the Slave of the PCM interface, i40e accepts PCM_CLK and PCM_SYNC. PCM_CLK rates up to 2048kHz are accepted. See Figure 8 below. Figure 8 i40e as PCM 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 i40e is configured as PCM Master, generating PCM_SYNC and PCM_CLK, then PCM_SYNC is 8-bits long. When BlueCore4-External is configured as PCM Slave, PCM_SYNC may be from two consecutive falling edges of PCM_CLK to half the PCM_SYNC rate, i.e. 62.5s long. See Figure 9 below. 18 / 37 BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet i40e samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising edge. PCM_OUT may be configured to be high impedance on the falling edge of PCM_CLK in the LSB position or on the rising edge. Figure 9 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. See Figure 10 below. Figure 10 Short Frame Sync (shown with 16-bit companded sample) As with Long Frame Sync, I40e samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising edge. PCM_OUT may be configured to be high impedance on the falling edge of PCM_CLK in the LSB position or on the rising edge. 4.3.4 Multi Slot Operation More than one SCO connection over the PCM interface is supported using multiple slots. Up to three SCO connections can be carried over any of the first four slots. See Figure 11 below. 19 / 37 BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet Figure 11 Multi Slot Operation (shown with two slots and 8-bit companded samples) 4.3.5 GCI Interface i40e is compatible with the General Circuit Interface, a standard synchronous 2B+D ISDN timing interface. The two 64Kbps B channels can be accessed when this mode is configured. See Figure 12 below. Figure 12 GCI Interface The start of frame is indicated by the rising edge of PCM_SYNC and runs at 8K Hz. With i40e in Slave mode, the frequency of PCM_CLK can be up to 4.096MHz. 4.3.6 Slots and Sample Formats i40e can receive and transmit on any selection of the first four slots following each sync pulse. Slot durations can be either 8 or 16 clock cycles. Durations of 8 clock cycles may only be used with 8-bit sample formats. Durations of 16 clocks may be used with 8, 13 or 16-bit sample formats. i40e supports 13-bit linear, 16-bit linear and 8-bit -law or A-law sample formats. The sample rate is 8ksamples/s. The bit order may be little or big endian. When 16-bit slots are used, the 3 or 8 unused bits in each slot may be filled with sign extension, padded with zeros or a programmable 3-bit audio attenuation compatible with some Motorola CODECs. See Figure 13 20 / 37 BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet below. Figure 13 16-bit Slot with 13-bit Linear Sample and Audio Gain Selected 4.3.7 Additional Features i40e 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 Configuration The PCM configuration is set using two PS Keys, PSKEY_PCM_CONFIG32 and PSKEY_PCM_LOW_JITTER_CONFIG. They are summarized in Table 9 and Table 10below. The default for PSKEY_PCM_CONFIG32 key is 0x00800000 i.e. first slot following sync is active, 13-bit linear voice format, long frame sync and interface master generating 256kHz PCM_CLK from 4MHz internal clock with no tri-stating of PCM_OUT. Table 9 PSKEY_PCM_CONFIG32 Description Name Bit position Description

0 Set to 0 SLAVE MODE EN 1 0 selects Master mode with internal generation of PCM_CLK and PCM_SYNC. 1 selects Slave mode requiring externally generated PCM_CLK and PCM_SYNC. This should be set to 1 if 48M_PCM_CLK_GEN_EN (bit 11) is set. 0 selects long frame sync (rising edge indicates start of SHORT SYNC EN 2 frame), 1 selects short frame sync (falling edge indicates start of frame). 21 / 37 BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet

Some GCI MODE EN MUTE EN 48M PCM CLK GEN EN 9 10 11 CODECS utilize this to enter a low power state. 1 enables GCI mode. 1 forces PCM_OUT to 0. 0 sets PCM_CLK and PCM_SYNC generation via DDS from internal 4 MHz clock, as for BlueCore4-External. 1 sets PCM_CLK and PCM_SYNC generation via DDS from internal 48 MHz clock. LONG LENGTH SYNC EN

Figure 14 BlueSoleil Stack In this version of the stack firmware shown no host processor is required to run the Bluetooth protocol stack. All BlueSoleil stack layers, including application software, run on the internal RISC processor. The host processor interfaces to BlueSoleil stack via one or more of the physical interfaces. The most common interfacing is done via UART interface using the ASCII commands supported by the BlueSoleil stack. With these ASCII commands the user can access Bluetooth functionality without paying any attention to the complexity, which lies in the Bluetooth protocol stack. The user may write applications code to run on the host processor to control BlueSoleil stack 23 / 37 RadioRAMI/OHost ARM/MCU/Any CPUUART/USBBlueSoleilFirmwareHardwareL2CAP/eL2CAPSDPRFCOMMOBEX/FTP/OPPHFP/HSPPBAP/MAPA2DP/AVRCPMCUBaseband DSPLink ManagerHost Controller InterfaceGPIOPCM/I2SAnalogueAT CMDApplicationSPPi40e Solution BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet with ASCII commands and to develop Bluetooth applications. Please refer to BlueSoleil i40es programming manuals: BlueSoleil_i40e_SPP_programming_manual.pdf or BlueSoleil_i40e_Multi_programming_manual.pdf. 6 Enhanced Data Rate EDR has been introduced to provide 2x and optionally 3x data rates with minimal disruption to higher layers of the Bluetooth stack. CSR supports both of the new data rates, with i40e. i40e is compliant with revision v2.0.E.2 of the specification. 6.1 Enhanced Data Rate Baseband At the baseband level EDR uses the same 1.6kHz slot rate as basic data rate and therefore the packets can be 1, 3, or 5 slots long as per the basic data rate. Where EDR differs from the basic data rate is that in the same 1MHz symbol rate 2 or 3bits are used per symbol, compared to 1bit per symbol used by the basic data rate. To achieve the increase in number of bits symbol, two new modulation schemes have been introduced as summarized in Table 11 below, and the modulation schemes are explained in the further sections. Table 11 Data Rate Schemes Although the EDR uses new packets Link establishment and management are unchanged and still use Basic Rate packets. 6.2 Enhanced Data Rate _/4 DQPSK 4 DQPSK includes the following features:

4-state Differential Phase Shift Keying. 4-state Differential Phase Shift Keying. 2 bits determine phase shift between consecutive symbols. Refer to Table 12 below. S/4 rotation avoids phase shift of S, which would cause large amplitude variation. Raised Cosine pulse shaping filter to further reduce side band emissions.

The data here is given only for guidance on solder re-flow. i40e will withstand up to two re-flows to a maximum temperature of 245C. 8 Reliability and Environmental Specification 8.1 Temperature test Put the module in demo board which uses exit power supply, power on the module and connect to mobile. Then put the demo in the 40 space for 1 hour and then move to +85 space within 1minute, after 1 hour move back to 40 space within1 minute. This is 1 cycle. The cycles are 32 times and the units have to pass the testing. 8.2 Vibration Test The module is being tested without package. The displacement requests 1.5mm and sample is vibrated in three directions(X,Y,Z).Vibration frequency set as 0.5G , a sweep rate of 0.1 octave/min from 5Hz to 100Hz last for 90 minutes each direction. Vibration frequency set as 1.5G, a sweep rate of 0.25 octave/min from 100Hz to 500Hz last for 20 minutes each direction. 8.3 Desquamation test Use clamp to fix the module, measure the pull of the component in the module, make sure the module`s soldering is good. 8.4 Drop test Free fall the module (condition built in a wrapper which can defend ESD) from 150cm height to cement ground, each side twice, total twelve times.The appearance will not be damaged and all functions OK. 27 / 37 BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet 8.5 Packaging information After unpacking, the module should be stored in environment as follows:

Temperature: 25 2 Humidity: <60%

No acidity, sulfur or chlorine environment The module must be used in four days after unpacking. 9 Layout and Soldering Considerations 9.1 Soldering Recommendations BlueSoleil i40e is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile used is dependent on the thermal mass of the entire populated PCB, heat transfer efficiency of the oven and particular type of solder paste used. Consult the datasheet of particular solder paste for profile configurations. IVT Corporation will give following recommendations for soldering the module to ensure reliable solder joint and operation of the module after soldering. Since the profile used is process and layout dependent, the optimum profile should be studied case by case. Thus following recommendation should be taken as a starting point guide. 9.2 Layout Guidelines It is strongly recommended to use good layout practices to ensure proper operation of the module. Placing copper or any metal near antenna deteriorates its operation by having effect on the matching properties. Metal shield around the antenna will prevent the radiation and thus metal case should not be used with the module. Use grounding vias separated max 3 mm apart at the edge of grounding areas to prevent RF penetrating inside the PCB and causing an unintentional resonator. Use GND vias all around the PCB edges. The mother board should have no bare conductors or vias in this restricted area, because it is not covered by stop mask print. Also no copper (planes, traces or vias) are allowed in this area, because of mismatching the on-board antenna. 28 / 37 BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet Figure 18 i40e Restricted Area Following recommendations helps to avoid EMC problems arising in the design. Note that each design is unique and the following list do not consider all basic design rules such as avoiding capacitive coupling between signal lines. Following list is aimed to avoid EMC problems caused by RF part of the module. Use good consideration to avoid problems arising from digital signals in the design. Ensure that signal lines have return paths as short as possible. For example if a signal goes to an inner layer through a via, always use ground vias around it. Locate them tightly and symmetrically around the signal vias. Routing of any sensitive signals should be done in the inner layers of the PCB. Sensitive traces should have a ground area above and under the line. If this is not possible, make sure that the return path is short by other means (for example using a ground line next to the signal line). 10 Physical Dimensions BlueSoleil i40es dimension is 27mm(L)x13mm(W)x2.2mm(H). 29 / 37 BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet Figure 19 i40e Footprint 11 Package BlueSoleil i40e package information is summarized in Figure 20 and Figure 21 below. 30 / 37 BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet Figure 20 Reel Information 31 / 37 BlueSoleil EcoSystem BlueSoleil EcoSystem BlueSoleil EcoSystemBlueSoleil EcoSystem i40e Datasheet Figure 21 Tape Information 12 Certification 12.1 Bluetooth BlueSoleil i40e is qualified as a Bluetooth controller subsystem and it fulfills all the mandatory requirements of Bluetooth 2.1 + EDR core specification.
