document number: 002-15053 rev. *d page 10 of 155 advance cyw4356 2. power supplies and power management 2.1 power supply topology one buck regulator, multiple ldo regulators, and a power management unit (pmu) are integrated into the cyw4356. all regulators are programmable via the pmu. these blocks simplify power supply design for bluetooth, wlan, and fm functions in embedded designs. a single vbat (3.0v to 5.25v dc max.) and vio supply (1.8v to 3.3v ) can be used, with all additional voltages being provided by the regulators in the cyw4356. two control signals, bt_reg_on and wl_reg _on, are used to power-up the regulators an d take the respective section out of reset. the cbuck cldo and lnldo power up when any of the rese t signals are deasserted. all regulators are powered down only when both bt_reg_on and wl_reg_on are deasserted. the cldo and lnldo may be turned off/on based on the dynamic demands of the digital baseband. the cyw4356 allows for an extremely low power-consumption mode by completely shutting down the cbuck, cldo, and lnldo regulators. when in this state, lpldo1 (which is a low-power linear regulator supplied by the sy stem vio supply) provides the cyw4356 with all the voltages it requ ires, further reducing leakage currents. 2.2 cyw4356 pmu features vbat to 1.35vout (600 ma maximum) core-buck (cbuck) switching regulator vbat to 3.3vout (600 ma maximum) ldo3p3 vbat to 3.3vout (150 ma maximum) ldo3p3_b vbat to 2.5v out (70 ma maximum) btldo2p5 1.35v to 1.2vout (150 ma maximum) lnldo 1.35v to 1.2vout (300 ma maximum) cldo with bypass mode for deep-sleep additional internal ldos (not externally accessible) figure 3 illustrates the typical power topology for the cyw 4356. the shaded areas are internal to the cyw4356.

document number: 002-15053 rev. *d page 25 of 155 advance cyw4356 5.5.3 bbc power management the following are low-power operations for the bbc: physical layer packet-handling turns the rf on and off dynamically within transmit/receive packets. bluetooth-specified low-power connection mode s: sniff, hold, and park. while in these modes, the cyw4356 runs on the low-power oscillator and wakes up after a predefined time period. a low-power shutdown feature allows the device to be turned off while the host and any other devices in the system remain operational. when the cyw4356 is not needed in the system, the rf and core supplie s are shut down while the i/o remains powered. this allows the cyw4356 to effectively be off while keepi ng the i/o pins powered so they do not draw extra current fro m any other devices connected to the i/o. during the low-power shut-down st ate, provided vddio remains applied to the cy w4356, all outputs are tristated, and most input signals are disabled. input voltages must remain within the lim its defined for normal operation. this is done to prevent curren t paths or create loading on any digital signals in the system and enables the cyw4356 to be fully integrated in an embedded device to take full advantage of the lowest power-saving modes. two cyw4356 input signals are designed to be high-impedance inputs that do not load the driving signal even if the chip does not have vddio power supplied to it: the frequency reference i nput (wrf_tcxo_in) and the 32.768 khz input (lpo). when the cyw4356 is powered on from this state, it is the same as a normal power-up, and the device does not contain any information about its state from the time before it was powered down. 5.5.4 fm power management the cyw4356 fm subsystem can operate independently of, or in tandem with, the bluetooth rf and bbc subsystems. the fm subsystem power management scheme operates in conjunction with the bluetooth rf and bbc subsystems. the fm block does not have a low power state, it is either on or off. 5.5.5 wideband speech the cyw4356 provides support for wideband speech (wbs) usin g on-chip smartaudio technology. the cyw4356 can perform subband-codec (sbc), as well as msbc, en coding and decoding of linear 16 bits at 16 khz (256 kbps rate) transferred over the pcm bus. 5.5.6 packet loss concealment packet loss concealment (plc) improves apparent audio quality fo r systems with marginal link performance. bluetooth messages are sent in packets. when a packet is lost, it creates a gap in the received audio bit-stream. packet loss can be mitigated in several ways: fill in zeros. ramp down the output audio signal toward zero (this is the method used in current bluetooth headsets). repeat the last frame (or packet) of the received bi t-stream and decode it as usual (frame repeat). these techniques cause distortion and popping in the audio stream . the cyw4356 uses a proprietar y waveform extension algorithm to provide dramatic improv ement in the audio quality. figure 10 and figure 11 show audio waveforms with and without packet loss concealment. cypress plc/bec algori thms also support wideband speech. figure 10. cvsd decoder output waveform without plc packet loss causes ramp-down
document number: 002-15053 rev. *d page 26 of 155 advance cyw4356 figure 11. cvsd decoder output waveform after applying plc 5.5.7 audio rate-matching algorithms the cyw4356 has an enhanced rate-matching algorithm that uses in terpolation algorithms to reduce audio stream jitter that may b e present when the rate of audio data coming from the host is not the same as the bluetooth or fm audio data rates. 5.5.8 codec encoding the cyw4356 can support sbc and msbc encoding and decoding for wideband speech. 5.5.9 multiple simult aneous a2dp audio stream the cyw4356 has the ability to take a single audio stream and ou tput it to multiple bluetooth devices simultaneously. this allo ws a user to share his or her music (or any audio stream) with a friend. 5.5.10 fm over bluetooth fm over bluetooth enables the cyw4356 to st ream data from fm over bluetooth without requiring the host to be awake. this can significantly extend battery life for us age cases where someone is listening to fm radio on a bluetooth headset. 5.5.11 burst buffer operation the cyw4356 has a data buffer that can buffer data being sent over the hci and audio transports, then send the data at an incre ased rate. this mode of operat ion allows the host to sleep for the maximum amo unt of time, dramatically reducing system current consumption. 5.6 adaptive frequency hopping the cyw4356 gathers link quality statistics on a channel by channel basis to faci litate channel assessment and channel map selection. the link quality is determined using both rf and base band signal processing to provide a more accurate frequency-hop map. 5.7 advanced bluetooth/wlan coexistence the cyw4356 includes advanced coexistence technologies that are only possible with a bluetooth/wlan integrated die solution. these coexistence technol ogies are targeted at small form-factor platforms, such as cell pho nes and media play ers, including ap pli- cations such as vowlan + sco and video-over-wlan + high fidelity bt stereo. support is provided for platforms that share a single antenna between bluetooth and wlan. dual-antenna applications are also supported. the cyw4356 radio architecture allows for lossless simultaneous bluetoot h and wlan reception for shared antenna applications. this is possible only via an integrated solution (shared lna and joint agc algorithm). it has superior performanc e versus implementations that need to arbitrate between bluetooth and wlan reception. the cyw4356 integrated solution enables mac-layer signaling (fi rmware) and a greater degree of sharing via an enhanced coexis- tence interface. information is exchanged between the blue tooth and wlan cores without host processor involvement. the cyw4356 also supports transmit power control on the sta toge ther with standard bluetooth tpc to limit mutual interference and receiver desensitization. pr eemption mechanisms are utilized to prevent ap transmissions from colliding with bluetooth fram es. improved channel classification techniques have been implemented in bluetooth for faster and more accurate detection and elimi- nation of interferers (including non-wlan 2.4 ghz interference). the bluetooth afh classification is also enhanced by the wlan core?s channel information. 5.8 fast connection (interlaced page and inquiry scans) the cyw4356 supports page scan and inquiry scan modes that si gnificantly reduce the average inquiry response and connection times. these scanning modes are compatible with the bluetooth version 2.1 page and inquiry procedures.

document number: 002-15053 rev. *d page 28 of 155 advance cyw4356 7. bluetooth periph eral transport unit 7.1 spi interface the cyw4356 supports a slave spi hci transport with an input cl ock range of up to 16 mhz. higher clock rates can be possible. t he physical interface between the spi master and the cyw4356 consists of the four spi signals (spi_csb, spi_clk, spi_si, and spi_so) and one interrupt signal (spi_int). the spi signals are muxed onto the uart signals, see table 7 . the cyw4356 can be configured to accept active-low or active-high polarity on t he spi_csb chip select signal. it can also be configured to drive a n active- low or active-high spi_int interrupt signal. bit ordering on th e spi_si and spi_so data lines can be configured as either littl e-endian or big-endian. additionally, proprietary sleep mode and half-dupl ex handshaking is implemented between the spi master and the cyw4356. the spi_int is required to negotiate the start of a transaction. the spi interface does not require flow control in th e middle of a payload. the fifo is large enough to ha ndle the largest packet size. only the spi master can stop the flow of bytes on the data lines, since it controls spi_csb and spi_clk. flow cont rol should be implemented in the higher layer protocols. 7.2 spi/uart transport detection the bt_host_wake (bt_gpio1) pin is also used for bt transpor t detection. the transport dete ction occurs during the power-up sequence. it selects either uart or spi tr ansport operation based on the following pin state: if the bt_host_wake (bt_gpio1) pin is pulle d low by an external pull-dow n during power-up, it select s the spi transport interfa ce. if the bt_host_wake (bt_gpio1) pin is not pu lled low externally during power -up, then the default inte rnal pull-up is detected as a high and it selects t he uart transport interface. when the a4wp feature is not used and usb is selected as the bluetooth interface to the host, an external pull-up (outside the chip) 10 k ? resistor to bt_vddio is required. the pull-up is not necessary but is recommended when the bluetooth/host interface is uart instead of usb. 7.3 pcm interface the cyw4356 supports two independent pcm in terfaces that share the pins with the i 2 s interfaces. the pcm interface on the cyw4356 can connect to linear pcm codec devices in master or slave mode. in master mode, the cyw4356 generates the pcm_clk and pcm_sync signals, and in slave mode, these signals are provi ded by another master on the pcm interface and are inputs to the cyw4356. the configuration of the pcm interface may be adjusted by the host through the use of vendor-specific hci commands. 7.3.1 slot mapping the cyw4356 supports up to three simultaneous full-duplex sc o or esco channels through the pcm interface. these three channels are time-multiplexed onto the single pcm interface by us ing a time-slotting scheme where the 8 khz or 16 khz audio sam ple interval is divided into as many as 16 slots. the number of slots is dependent on the selected in terface rate of 128 khz, 512 k hz, or 1024 khz. the corresponding number of slots for these interface rate is 1, 2, 4, 8, and 16, respectively. transmit and receive pcm data from an sco channel is always mapped to the same slot. t he pcm data output driver tristate s its output on unused slots to allow other devices to share the same pcm interface signals. the data output driver tristates its ou tput after the falling edge of th e pcm clock during the last bit of the slot. 7.3.2 frame synchronization the cyw4356 supports both short- and long-frame synchronization in both master and slave modes. in short-frame synchronization mode, the frame synchronization signal is an active-high pulse at the audio frame rate that is a single-bit period in width and is synchronized to the rising edge of the bit clock. the pcm slave looks for a high on the falling edge of the bit clock and expec ts the first bit of the first slot to start at th e next rising edge of the cl ock. in long-frame synchroni zation mode, the frame synchr onization signal is again an active-high pulse at the audio frame rate; however, the duration is three bit periods and the pulse starts c oincident with the first bit of the first slot. table 7. spi to uart signal mapping spi signals uart signals spi_clk uart_cts_n spi_csb uart_rts_n spi_miso uart_txd spi_mosi uart_rxd spi_int bt_dev_wake
document number: 002-15053 rev. *d page 29 of 155 advance cyw4356 7.3.3 data formatting the cyw4356 may be configured to generate and accept several di fferent data formats. for conventional narrowband speech mode, the cyw4356 uses 13 of the 16 bits in each pcm frame. the lo cation and order of these 13 bits can be configured to support vari ous data formats on the pcm interface. the remaining three bits are ignored on the input and may be filled with 0s, 1s, a sign bit, or a programmed value on the output. the default format is 13-bit 2? s complement data, left justified, and clocked msb first. 7.3.4 wideband speech support when the host encodes wideband speech (wbs) packets in transpa rent mode, the encoded packets are transferred over the pcm bus for an esco voice connection. in this mode, the pcm bus is ty pically configured in master m ode for a 4 khz sync rate with 1 6- bit samples, resulting in a 64 kbps bit rate. the cyw4356 also supports slave transparent mode using a proprietary rate-matchin g scheme. in sbc-code mode, linear 16-bit data at 16 kh z (256 kbps rate) is transferred over the pcm bus. 7.3.5 multiplexed bluetooth and fm over pcm in this mode of operation, the cyw4356 multiplexes both fm a nd bluetooth audio pcm channels over the same interface, reducing the number of required i/os. this mode of operation is initiate d through an hci command from the host. the format of the data s tream consists of three channels: a bluetooth channel followed by two fm channels (audio left and right). in this mode of operation, the bus data rate only supports 48 khz operation per channel with 16 bits sent for each channel. this is done to allow the low data rat e bluetooth data to coexist in the sa me interface as the higher speed i 2 s data. to accomplish this, the bluetooth data is repeated six times for 8 khz data and three times for 16 khz data. an initial sync pulse on the pcm_sync line is used to indicate the beginn ing of the frame. to support multiple bluetooth audio stream s within the bluetooth channel, both 16 khz and 8 khz streams can be multiplexed. thi s mode of operation is only supported when the bluetooth host is the master. figure 12 shows the operation of th e multiplexed transport with three simultaneous sco connections. to accommodate additi onal sco channels, the transport clock speed is increased. to change between modes of operation, the transport must be halted and restarted in the new configuration. figure 12. functional multiplex data diagram 7.3.6 burst pcm mode in this mode of operation, the pcm bus runs at a significantly higher rate of operati on to allow the host to duty cycle its ope ration and save current. in this mode of operation, the pcm bus can operate at a rate of up to 24 mhz. this mode of operation is initiated with an hci command from the host. pcm_sync pcm_in pcm_out fm ? right fm ? left fm ? right fm ? left bt ? sco ? 1 ? tx bt ? sco ? 2 ? tx bt ? sco ? 3 ? tx bt ? sco ? 1 ? rx bt ? sco ? 2 ? rx bt ? sco ? 3 ? rx 1 ? frame pcm_clk 16 ? bits ? per ? sco ? frame ? clk 16 ? bits ? per ? frame ? 16 ? bits ? per ? frame ? each ? sco ? channel ? duplicates ? the ? data ? 6 ? times. ?? each ? wbs ? frame ? duplicates ? the ? data ? three ? times ? per ? frame
