The power-management module is optimized for drawing extremely low currents. 5.7.1.1 Power Sources The CC256x device requires two power sources: • VDD_IN: main power supply for the device • VDD_IO: power source for the 1.8-V I/O ring The HCI module includes several on-chip voltage regulators for increased noise immunity and can be connected directly to the battery. 5.7.1.2 Device Power-Up and Power-Down Sequencing The device includes the following power-up requirements (see Figure 5-1): • nSHUTD must be low. VDD_IN and VDD_IO are don't-care when nSHUTD is low. However, signals are not allowed on the I/O pins if I/O power is not supplied, because the I/Os are not fail-safe. Exceptions are SLOW_CLK_IN and AUD_xxx, which are fail-safe and can tolerate external voltages with no VDD_IO and VDD_IN. • VDD_IO and VDD_IN must be stable before releasing nSHUTD. • The fast clock must be stable within 20 ms of nSHUTD going high. • The slow clock must be stable within 2 ms of nSHUTD going high. The device indicates that the power-up sequence is complete by asserting RTS low, which occurs up to 100 ms after nSHUTD goes high. If RTS does not go low, the device is not powered up. In this case, ensure that the sequence and requirements are met.

The rise time for nSHUTD must not exceed 20 μs; nSHUTD must be low for a minimum of 5 ms. To prevent conflicts with external signals, all I/O pins are set to the high-impedance (Hi-Z) state during shutdown and power up of the device.

One and only one technology or assisted mode can be used at a time. Figure 6-1. CC256x Functional Block Diagram 6.3 Clock Inputs This section describes the available clock inputs. For specifications, see Section 5.7.2, Clock Specifications. 6.3.1 Slow Clock An external source must supply the slow clock and connect to the SLOW_CLK_IN pin (for example, the host or external crystal oscillator). The source must be a digital signal in the range of 0 to 1.8 V. The accuracy of the slow clock frequency must be 32.768 kHz ±250 ppm for Bluetooth use (as specified in the Bluetooth specification). The external slow clock must be stable within 64 slow-clock cycles (2 ms) following the release of nSHUTD. 6.3.2 Fast Clock Using External Clock Source An external clock source is fed to an internal pulse-shaping cell to provide the fast-clock signal for the device. The device incorporates an internal, automatic clock-scheme detection mechanism that automatically detects the fast-clock scheme used and configures the FREF cell accordingly. This mechanism ensures that the electrical characteristics (loading) of the fast-clock input remain static regardless of the scheme used and eliminates any power-consumption penalty-versus-scheme used. The frequency variation of the fast-clock source must not exceed ±20 ppm (as defined by the Bluetooth specification). The external clock can be AC- or DC-coupled, sine or square wave.

The signal received from the external antenna is input to a single-ended low-noise amplifier (LNA) and passed to a mixer that downconverts the signal to IF, followed by a filter and amplifier. The signal is then quantized by a sigma-delta analog-to-digital converter (ADC) and further processed to reduce the interference level. The demodulator digitally downconverts the signal to zero-IF and recovers the data stream using an adaptive-decision mechanism. The demodulator includes EDR processing with: • State-of-the-art performance • A maximum-likelihood sequence estimator (MLSE) to improve the performance of basic-rate GFSK sensitivity • Adaptive equalization to enhance EDR modulation New features include: • LNA input range narrowed to increase blocking performance • Active spur cancellation to increase robustness to spurs 6.4.1.2 Transmitter The transmitter is an all-digital, sigma-delta phase-locked loop (ADPLL) based with a digitally controlled oscillator (DCO) at 2.4 GHz as the RF frequency clock. The transmitter directly modulates the digital PLL. The power amplifier is also digitally controlled. The transmitter uses the polar-modulation technique. While the phase-modulated control word is fed to the ADPLL, the amplitude-modulated controlled word is fed to the class-E amplifier to generate a Bluetooth standard-compliant RF signal. New features include: • Improved TX output power • LMS algorithm to improve the differential error vector magnitude (DEVM) 6.4.2 Host Controller Interface The CC256x device incorporates one UART module dedicated to the HCI transport layer. The HCI interface transports commands, events, and ACL between the device and the host using HCI data packets. All members of the CC256x family supand port the H4 protocol (4-wire UART) with hardware flow control. The CC2560B and CC2564B devices also support the H5 protocol (3-wire UART) with software flow control. The CC256x device automatically detects the protocol when it receives the first command. The maximum baud rate of the UART module is 4 Mbps; however, the default baud rate after power up is set to 115.2 kbps. The baud rate can thereafter be changed with a VS command. The device responds with a command complete event (still at 115.2 kbps), after which the baud rate change occurs.

Figure 6-10 shows the H4 UART interface. Host_RX HCI_RX Host_TX HCI_TX Host_CTS HCI_CTS Host_RTS HCI_RTS Host CC256x SWRS121-003 Figure 6-10. H4 UART Interface When the UART RX buffer of the device passes the flow control threshold, it sets the HCI_RTS signal high to stop transmission from the host. When the HCI_CTS signal is set high, the device stops transmission on the interface. If HCI_CTS is set high while transmitting a byte, the device finishes transmitting the byte and stops the transmission. The H4 protocol device includes a mechanism that handles the transition between active mode and sleep mode. The protocol occurs through the CTS and RTS UART lines and is known as the enhanced HCI low level (eHCILL) power-management protocol.

The interface includes the following features: • Two voice channels • Master and slave modes • All voice coding schemes defined by the Bluetooth specification: linear, A-Law, and μ-Law • Long and short frames • Different data sizes, order, and positions • High flexibility to support a variety of codecs • Bus sharing: Data_Out is in Hi-Z state when the interface is not transmitting voice data. 6.4.3.1 Hardware Interface The interface includes four signals: • Clock: configurable direction (input or output) • Frame_Sync and Word_Sync: configurable direction (input or output) • Data_In: input • Data_Out: output or 3-state The CC256x device can be the master of the interface when generating the Clock and Frame_Sync signals or the slave when receiving these two signals. For slave mode, clock input frequencies of up to 15 MHz are supported. At clock rates above 12 MHz, the maximum data burst size is 32 bits. For master mode, the device can generate any clock frequency between 64 kHz and 4.096 MHz. 6.4.3.2 I2S When the codec interface is configured to support the I2S protocol, these settings are recommended: • Bidirectional, full-duplex interface • Two time slots per frame: time slot-0 for the left channel audio data; and time slot-1 for the right channel audio data • Each time slot is configurable up to 40 serial clock cycles long, and the frame is configurable up to 80 serial clock cycles long. 6.4.3.3 Data Format The data format is fully configurable: • The data length can be from 8 to 320 bits in 1-bit increments when working with 2 channels, or up to 640 bits when working with 1 channel. The data length can be set independently for each channel. • The data position within a frame is also configurable within 1 clock (bit) resolution and can be set independently (relative to the edge of the Frame_Sync signal) for each channel.

For example; Data_In can start with the most significant bit (MSB); Data_Out can start with the least significant bit (LSB). Each channel is separately configurable. The inverse bit order (that is, LSB first) is supported only for sample sizes up to 24 bits. Data_In and Data_Out are not required to be the same length. The Data_Out line is configured to Hi-Z output between data words. Data_Out can also be set for permanent Hi-Z, regardless of the data output. This configuration allows the device to be a bus slave in a multislave PCM environment. At power up, Data_Out is configured as Hi-Z. Frame Idle Period The codec interface handles frame idle periods, in which the clock pauses and becomes 0 at the end of the frame, after all data are transferred. The device supports frame idle periods both as master and slave of the codec bus. When the device is the master of the interface, the frame idle period is configurable. There are two configurable parameters: • Clk_Idle_Start: indicates the number of clock cycles from the beginning of the frame to the beginning of the idle period. After Clk_Idle_Start clock cycles, the clock becomes 0. • Clk_Idle_End: indicates the time from the beginning of the frame to the end of the idle period. The time is given in multiples of clock periods. The delta between Clk_Idle_Start and Clk_Idle_End is the clock idle period. For example, for clock rate = 1 MHz, frame sync period = 10 kHz, Clk_Idle_Start = 60, Clk_Idle_End = 90. Between both Frame_Sync signals there are 70 clock cycles (instead of 100). The clock idle period starts 60 clock cycles after the beginning of the frame and lasts 90 – 60 = 30 clock cycles. Thus, the idle period ends 100 – 90 = 10 clock cycles before the end of the frame. The data transmission must end before the beginning of the idle period. Figure 6-12 shows the frame idle timing.

Frame Idle Period 6.4.3.5 Clock-Edge Operation The codec interface of the device can work on the rising or the falling edge of the clock and can sample the Frame_Sync signal and the data at inversed polarity. 28 Detailed Description Copyright © 2012–2016, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: CC2560A CC2560B CC2564 CC2564B CC2560A NRND; CC2564 NRND CC2560A, CC2560B, CC2564, CC2564B www.ti.com SWRS121E – JULY 2012 – REVISED JANUARY 2016 Figure 6-13 shows the operation of a falling-edge-clock type of codec. The codec is the master of the bus. The Frame_Sync signal is updated (by the codec) on the falling edge of the clock and is therefore sampled (by the device) on the next rising clock.

There are two options: • Repeat the last sample: possible only for sample sizes up to 24 bits. For sample sizes larger than 24 bits, the last byte is repeated. • Repeat a configurable sample of 8 to 24 bits (depending on the real sample size) to simulate silence (or anything else) in the bus. The configured sample is written in a specific register for each channel. The choice between those two options is configurable separately for each channel. 6.4.3.8 Bluetooth and Codec Clock Mismatch Handling In Bluetooth RX, the device receives RF voice packets and writes them to the codec interface. If the device receives data faster than the codec interface output allows, an overflow occurs. In this case, the Bluetooth RX has two possible modes of behavior: Copyright © 2012–2016, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: CC2560A CC2560B CC2564 CC2564B Detailed Description 29 CC2560A NRND; CC2564 NRND CC2560A, CC2560B, CC2564, CC2564B SWRS121E – JULY 2012 – REVISED JANUARY 2016 • Allow overflow: if overflow is allowed, the Bluetooth RX continues receiving data and overwrites any data not yet sent to the codec. Do not allow overflow: if overflow is not allowed, RF voice packets received when the buffer is full are discarded. • 6.4.4 www.ti.com Assisted Modes (CC2560B and CC2564B Devices) The CC256x device contains an embedded coprocessor that can be used for multiple purposes (see Figure 1-1). The CC2564 and CC2564B devices use the coprocessor to perform the LE or ANT functionality. The CC256x device uses the coprocessor to execute the assisted HFP 1.6 (WBS) or assisted A2DP functions. Only one of these functions can be executed at a time because they all use the same resources (that is, the coprocessor; see Table 3-1 for the modes of operation supported by each device). This section describes the assisted HFP 1.6 (WBS) and assisted A2DP modes of operation in the CC256x device. These modes of operation minimize host processing and power by taking advantage of the device coprocessor to perform the voice and audio SBC processing required in HFP 1.6 (WBS) and A2DP profiles. This section also compares the architecture of the assisted modes with the common implementation of the HFP 1.6 and A2DP profiles. The assisted HFP 1.6 (WBS) and assisted A2DP modes of operation comply fully with the HFP 1.6 and A2DP Bluetooth specifications. For more information on these profiles, see the corresponding Bluetooth Profile Specification (www.bluetooth.org/en-us/specification/adopted-specifications). 6.4.4.1 Assisted HFP 1.6 (WBS) The HFP 1.6 Profile Specification adds the requirement for WBS support. The WBS feature allows twice the voice quality versus legacy voice coding schemes at the same air bandwidth (64 kbps). This feature is achieved using a voice sampling rate of 16 kHz, a modified subband coding (mSBC) scheme, and a packet loss concealment (PLC) algorithm. The mSBC scheme is a modified version of the mandatory audio coding scheme used in the A2DP profile with the parameters listed in Table 6-3. Table 6-3. mSBC Parameters PARAMETER VALUE Channel mode Mono Sampling rate 16 kHz Allocation method Loudness Subbands 8 Block length 15 Bitpool 26 The assisted HFP 1.6 mode of operation implements this WBS feature on the embedded CC256x coprocessor. That is, the mSBC voice coding scheme and the PLC algorithm are executed in the CC256x coprocessor rather than in the host, thus minimizing host processing and power. One WBS connection at a time is supported and WBS and NBS connections cannot be used simultaneously in this mode of operation. Figure 6-15 shows the architecture comparison between the common implementation of the HFP 1.6 profile and the assisted HFP 1.6 solution. 30 Detailed Description Copyright © 2012–2016, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: CC2560A CC2560B CC2564 CC2564B CC2560A NRND; CC2564 NRND CC2560A, CC2560B, CC2564, CC2564B www.ti.com SWRS121E – JULY 2012 – REVISED JANUARY 2016 Figure 6-15. HFP 1.6 Architecture Versus Assisted HFP 1.6 Architecture For detailed information on the HFP 1.6 profile, see the Hands-Free Profile 1.6 Specification (www.bluetooth.org/en-us/specification/adopted-specifications). 6.4.4.2 Assisted A2DP The advanced audio distribution profile (A2DP) enables wireless transmission of high-quality mono or stereo audio between two devices. A2DP defines two roles: • A2DP source is the transmitter of the audio stream. • A2DP sink is the receiver of the audio stream. A typical use case streams music from a tablet, phone, or PC (the A2DP source) to headphones or speakers (the A2DP sink). This section describes the architecture of these roles and compares them with the corresponding assisted-A2DP architecture. To use the air bandwidth efficiently, the audio data must be compressed in a proper format. The A2DP mandates support of the SBC scheme. Other audio coding algorithms can be used; however, both Bluetooth devices must support the same coding scheme. SBC is the only coding scheme spread out in all A2DP Bluetooth devices, and thus the only coding scheme supported in the assisted A2DP modes. Table 6-4 lists the recommended parameters for the SBC scheme in the assisted A2DP modes. Table 6-4.

In this role, the A2DP layer and its underlying layers are responsible for link management and data decoding. To handle these tasks, two logic transports are defined: • Control and signaling logic transport • Data packet logic transport The assisted A2DP takes advantage of this modularity to handle the data packet logic transport in the CC256x device by implementing a light L2CAP layer (L-L2CAP) and light AVDTP layer (L-AVDTP) to defragment the packets. Then the assisted A2DP performs the SBC decoding on-chip to deliver raw audio data through the CC256x PCM–I2S interface. Figure 6-16 shows the comparison between a common A2DP sink architecture and the assisted A2DP sink architecture.

Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949 and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements. Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S. TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product). Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory requirements in connection with such selection.
