Bluegiga Technologies Oy Page 12 of 52 5 Layout Guide Lines Use good layout practices to avoid excessive noise coupling to supply voltage traces or sensitive analog signal traces. If using overlapping ground planes use stitching vias separated by max 3 mm to avoid emission from the edges of the PCB. Connect all the GND pins directly to a solid GND plane and make sure that there is a low impedance path for the return current following the signal and supply traces all the way from start to the end. A good practice is to dedicate one of the inner layers to a solid GND plane and one of the inner layers to supply voltage planes and traces and route all the signals on top and bottom layers of the PCB. This arrangement will make sure that any return current follows the forward current as close as possible and any loops are minimized. SignalsGNDPowerSignals Figure 5: Typical 4-layer PCB construction Overlapping GND layers without GND stitching viasOverlapping GND layers with GND stitching vias shielding the RF energy Figure 6: Use of stitching vias to avoid emissions from the edges of the PCB 5.1 BT111-A Layout Guide For optimal performance of the antenna place the module at the corner of the PCB of the mother board as shown in the figure 7. Optionally the module can be placed on the long edge of the mother board. In this case the metal clearance area must be extended minimum 10mm from the edge of the module, as shown in figure 7. The layout of the mother board has an impact on the antenna characteristic and radiation pattern, see the antenna characteristics chapter. Do not place any metal (traces, components, battery etc.) within the clearance area of the antenna. Connect all the GND pins directly to a solid GND plane. Place the GND vias as close to the GND pins as possible. Use good layout practices to avoid any excessive noise coupling to signal lines or supply voltage lines. Avoid placing plastic or any other dielectric material closer than 5 mm from the antenna. Any dielectric closer than 5 mm from the antenna will detune the antenna to lower frequencies. The antenna is optimized for mother board thickness of 1.0 mm. If the mother board is thicker than this, the resonant frequency will be tuned downwards. If the mother board thickness is thinner than 1.0 mm, the

Bluegiga Technologies Oy Page 13 of 52 resonant frequency will be tuned upwards. S11 is a measure of how big portion of the transmitted power is reflected back from the antenna. An adequate performance can be expected if S11 is less than – 7 dB. If using PCB thickness more than 1.6 mm, or if there is dielectric material around the antenna which is likely to detune the resonant frequency, the antenna can be tuned in the mother board layout by removing FR4 below the antenna.

The radiation pattern is strongly dependent on the layout of the mother board. Usually the gain is highest to the directions where there is most GND and weakest to the opposite direction. Typically the total radiated efficiency is around 25% - 35%. The maximum gain is 0.5 dBi.

Bluegiga Technologies Oy Page 22 of 52 8 Clock Generation BT111 is using an internal 26 MHz crystal oscillator. All internal digital clocks are generated using a phase locked loop, which is locked to the 26 MHz crystal oscillator. 26 MHz clock is calibrated in production and the calibrated settings are stored to the internal EEPROM of BT111. The 32.768 kHz sleep clock is generated internally to the module. BT111 does not need any external clock sources.

Bluegiga Technologies Oy Page 23 of 52 9 Bluetooth Stack Microcontroller BT111 uses a 16-bit RISC MCU for low power consumption and efficient use of memory.

The internal EEPROM is powered from VDD_PADS. The minimum supply voltage writing the EEPROM is 2.7V and the minimum supply voltage for reading the EEPROM is 1.7V.

Bluegiga Technologies Oy Page 25 of 52 13 Serial Interfaces 13.1 USB Interface BT111 has a full-speed (12Mbps) USB interface for communicating with other compatible digital devices. The USB interface on BT111 acts as a USB peripheral, responding to requests from a master host controller. BT111 supports the Universal Serial Bus Specification, Revision v2.0 (USB v2.0 Specification) and USB Battery Charging Specification, available from http://www.usb.org. For more information on how to integrate the USB interface on BT111 see the WTxx / BTxxx USB Design Guide. As well as describing USB basics and architecture, the application note describes:  Power distribution for high and low bus-powered configurations  Power distribution for self-powered configuration, which includes USB VBUS monitoring  USB enumeration  Electrical design guidelines for the power supply and data lines, as well as PCB tracks and the effects of ferrite beads  USB suspend modes and Bluetooth low-power modes:  Global suspend  Selective suspend, includes remote wake  Wake on Bluetooth, includes permitted devices and set-up prior to selective suspend  Suspend mode current draw  PIO status in suspend mode  Resume, detach and wake PIOs  Battery charging from USB, which describes dead battery provision, charge currents, charging in suspend Modes and USB VBUS voltage consideration  USB termination when interface is not in use  Internal modules, certification and non-specification compliant operation See chapter 17 for the default USB vendor and product ID settings. 13.2 Programming and Debug Interface This SPI programming and debug interface can configure the PS Keys stored in the internal EEPROM and can also debug BT111. Bluegiga provides the development and production tools to communicate over this interface from a PC. BT111 uses a 16-bit data and 16-bit address programming and debug interface. Transactions occur when the internal processor is running or is stopped. Data is written or read one word at a time, or the auto-increment feature is available for the block access. Configuring the parameters of the BT111 and running test scripts is also possible via the USB interface with certain limitations; please see Section 14 for more information.

Bluegiga Technologies Oy Page 26 of 52 14 Audio Interfaces BT111 has digital audio interface that is configurable as either a PCM or I2S port. 14.1 PCM Interface The audio PCM interface on the BT111 supports:  Continuous transmission and reception of PCM encoded audio data over Bluetooth.  Processor overhead reduction through hardware support for continual transmission and reception of PCM data.  A bidirectional digital audio interface that routes directly into the baseband layer of the firmware. It does not pass through the HCI protocol layer.  Hardware on BT111 for sending data to and from a SCO connection.  Up to 3 SCO connections on the PCM interface at any one time.  PCM interface master, generating PCM_SYNC and PCM_CLK.  PCM interface slave, accepting externally generated PCM_SYNC and PCM_CLK.  Various clock formats including: o Long Frame Sync o Short Frame Sync o GCI timing environments  13-bit or 16-bit linear, 8-bit μ-law or A-law companded sample formats.  Receives and transmits on any selection of 3 of the first 4 slots following PCM_SYNC. The PCM configuration options are enabled by setting PSKEY_PCM_CONFIG32. 14.1.1 PCM Interface Master/Slave When configured as the master of the PCM interface, BT111 generates PCM_CLK and PCM_SYNC.

Bluegiga Technologies Oy Page 27 of 52 PCM_OUTPCM_INPCM_CLKPCM_SYNCUp to 2400kHz8/48kHz Figure 16: BT111 as PCM slave 14.1.2 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 BT111 is configured as PCM master, generating PCM_SYNC and PCM_CLK, then PCM_SYNC is 8 bits long. When BT111 is configured as PCM Slave, PCM_SYNC is from 1 cycle PCM_CLK to half the PCM_SYNC rate. Figure 17: Long Frame Sync (Shown with 8-bit Companded Sample) BT111 samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising edge. PCM_OUT is configurable as high impedance on the falling edge of PCM_CLK in the LSB position or on the rising edge. 14.1.3 Short Frame Sync In Short Frame Sync, the falling edge of PCM_SYNC indicates the start of the PCM word. PCM_SYNC is always 1 clock cycle long.

Bluegiga Technologies Oy Page 28 of 52 Figure 18: Short Frame Sync (shown with 16-bit sample) As with Long Frame Sync, BT111 samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising edge. PCM_OUT is configurable as high impedance on the falling edge of PCM_CLK in the LSB position or on the rising edge. 14.2 Multi-slot Operation More than 1 SCO connection over the PCM interface is supported using multiple slots. Up to 3 SCO connections are carried over any of the first 4 slots. Figure 19: Multi-slot Operation with 2 Slots and 8-bit Companded Samples 14.2.1 GCI Interface BT111 is compatible with the GCI, a standard synchronous 2B+D ISDN timing interface. The 2 64kbps B channels are accessed when this mode is configured.

Bluegiga Technologies Oy Page 29 of 52 Figure 20: GCI Interface The start of frame is indicated by the rising edge of PCM_SYNC and runs at 8kHz. 14.2.2 Slots and Sample Formats BT111 receives and transmits on any selection of the first 4 slots following each sync pulse. Slot durations are either 8 or 16 clock cycles:  8 clock cycles for 8-bit sample formats.  16 clock cycles for 8-bit, 13-bit or 16-bit sample formats. BT111 supports:  13-bit linear, 16-bit linear and 8-bit μ-law or A-law sample formats.  A sample rate of 8ksps.  Little or big endian bit order.  For 16-bit slots, the 3 or 8 unused bits in each slot are filled with sign extension, padded with zeros or a programmable 3-bit audio attenuation compatible with some codecs.

Bluegiga Technologies Oy Page 30 of 52 Figure 21: 16-bit Slot Length and Sample Formats 14.2.3 Additional Features BT111 has a mute facility that forces PCM_OUT to be 0. In master mode, BT111is compatible with some codecs which control power down by forcing PCM_SYNC to 0 while keeping PCM_CLK running.

Bluegiga Technologies Oy Page 34 of 52 Figure 25: PCM Slave Timing Short Frame Sync 14.2.5 PCM_CLK and PCM_SYNC Generation BT111 has 2 methods of generating PCM_CLK and PCM_SYNC in master mode:  Generating these signals by DDS from BT111 internal 4MHz clock. Using this mode limits PCM_CLK to 128, 256 or 512kHz and PCM_SYNC to 8kHz.  Generating these signals by DDS from an internal 48MHz clock, enables a greater range of frequencies to be generated with low jitter but consumes more power. To select this second method set bit 48M_PCM_CLK_GEN_EN in PSKEY_PCM_CONFIG32. When in this mode and with long frame sync, the length of PCM_SYNC is either 8 or 16 cycles of PCM_CLK, determined by LONG_LENGTH_SYNC_EN in PSKEY_PCM_CONFIG32. Following equation describes PCM_CLK frequency when generated from the internal 48MHz clock: Equation 1: PCM_CLK Frequency Generated Using the Internal 48MHz Clock Set the frequency of PCM_SYNC relative to PCM_CLK using following equation: Equation 2: PCM_SYNC Frequency Relative to PCM_CLK CNT_RATE, CNT_LIMIT and SYNC_LIMIT are set using PSKEY_PCM_LOW_JITTER_CONFIG. As an example, to generate PCM_CLK at 512kHz with PCM_SYNC at 8kHz, set PSKEY_PCM_LOW_JITTER_CONFIG to 0x08080177.

Bluegiga Technologies Oy Page 35 of 52 14.2.6 PCM Configuration Configure the PCM by using PSKEY_PCM_CONFIG32 and PSKEY_PCM_LOW_JITTER_CONFIG, see your PS Key file. The default for PSKEY_PCM_CONFIG32 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-state of PCM_OUT. 14.3 Digital Audio Interface (I2S) The digital audio interface supports the industry standard formats for I²S, left-justified or right-justified. The interface shares the same pins as the PCM interface, which means each audio bus is mutually exclusive in its usage. Table 17 lists these alternative functions. PCM Interface I2S InterfacePCM_OUT SD_OUTPCM_IN SD_INPCM_SYNC WSPCM_CLK SCK Table 18: Alternative Function of the Digital Audio Bus Interface on the PCM Interface Configure the digital audio interface using PSKEY_DIGITAL_AUDIO_CONFIG. Table 18 describes the values for the PS Key (PSKEY_DIGITAL_AUDIO_CONFIG) that is used to set-up the digital audio interface. For example, to configure an I2S interface with 16-bit SD data set PSKEY_DIGITAL_CONFIG to 0x0406.

Also the BT111 firmware automatically controls the regulators. Important Note: VREG_EN_RST# should not be taken high before the supply on VREG_IN_HV is present. The VREG_EN_RST# pin is connected internally to the reset function and is powered from VDD_PADS, so do not apply voltages above VDD_PADS to the VREG_EN_RST# pin. The VREG_EN_RST# pin is pulled down internally. 15.2 USB Linear Regulator The integrated USB LDO linear regulator is available as a 3.30V supply rail and is intended to supply the USB interface and the high-voltage linear regulator. The input voltage range is between 4.25V and 5.75V. The maximum current from this regulator is 150mA. This regulator is enabled by default. If the USB linear regulator is not required leave its input (VREG_IN_USB) unconnected. 15.3 High Voltage Linear Regulator The integrated high-voltage linear regulator is available to power the main 1.8V supply rail. The input voltage range is between 2.3V and 4.8V. The maximum current from this regulator is 100mA. Take VREG_EN_RST# high to enable this regulator. Important Note: VREG_EN_RST# should not be taken high before the supply on VREG_IN_HV is present. If this regulator is not required then leave VREG_IN_HV unconnected or tied to VREG_OUT_HV.

Bluegiga Technologies Oy Page 41 of 52 15.4 Low Voltage Linear Regulators BT111 has three integrated low voltage linear regulators providing the internal supply voltages for RF and digital circuits of BT111. The input voltage range is between 1.70V and 1.95V. 15.5 Powering Sequence All the power supplies should be powered at the same time. The order of powering the supplies relative to the I/O supply, VDD_PADS to VDD_HOST, is not important. If the I/O supply is powered before VDD_DIG, all digital I/Os are weak pull-downs irrespective of the reset state. 15.6 Reset The reset function is internally tied to the VREG_EN_RST# pin. BT111 is reset from several sources:  VREG_EN_RST# pin  Power-on reset  Via a software-configured watchdog timer The VREG_EN_RST# pin is an active low reset. Assert the reset signal for a period >5ms to ensure a full reset. Important Note: Bluegiga does not recommend assertions of the reset of <5ms on the VREG_EN_RST# pin, as any glitches on this line can affect I/O integrity without triggering a reset. A warm reset function is also available under software control. After a warm reset the RAM data remains available.
