All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 The BT850-Sx supports the proprietary Cypress Global Coexistence Interface (GCI) which is a two-wire interface. The following key features are associated with the interface: ▪ Enhanced coexistence data can be exchanged over GCI_SECI_IN and GCI_SECI_OUT a two-wire interface, one serial input (GCI_SECI_IN), and one serial output (GCI_SECI_OUT). The both pins are controlled by the configuration file that is stored in EEPROM from the host. ▪ It supports generic UART communication between WLAN and Bluetooth devices. ▪ To conserve power, it is disabled when inactive. ▪ It supports automatic resynchronization upon waking from sleep mode. ▪ It supports a baud rate of up to 4 Mbps. Table 10 shows the two-wire BT coexistence interface assignments. Table 10: BDR/EDR/LE receiver sensitivity (Input = 3V3 @ 25℃) Coexistence Signal Name Signal Assignment BT_SECI_IN GPIO_6 BT_SECI_OUT GPIO_7 BT85x has a full -speed (12 Mbps) USB interface for communicating with other compatible digital devices. The USB interface on the BT85x acts as a USB peripheral, responding to requests from a master host controller. BT85x supports the Universal Serial Bus Specification (USB v2.0 Specification) and USB Battery Charging Specification, available from http://www.usb.org. For more info rmation on how to int egrate the USB interface on BT8 5xd, see Figure 17 located in the following section: USB Dongle Design Example Using BT850. The following USB interface features are supported: ▪ USB Protocol, revision 2.0, full-speed compliant with LPM support (up to 12 Mbps) ▪ Bluetooth HCI ▪ Integrated detach resistor ▪ USB termination when interface is not in use ▪ Internal modules, certification, and non-specification compliant operation The BT850-Sx supports two independent PCM interfaces that share the pins with I 2S interfaces. The PCM interface on the BT850-Sx can connect to linear PCM Codec devices in master or slave mode. In master mode, the BT850 -Sx generates the PCM_CLK and PCM_SYNC signals; in slave mode, these signals are provided by another master on the PCM interface and are inputs to the BT850-Sx. The configuration of the PCM interface may be adjusted by the host using vendor-specific HCI commands. For additional information, refer to the DVK-BT85x-Sx User Guide available from the BT85x product page of the Laird website.

All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 The BT850-Sx supports up to three simultaneous full -duplex SCO or eSCO channels through the PCM interface. These three channels are time-multiplexed onto the single PCM interface by using a time-slotting scheme where the 8 kHz or 16 kHz audio sample interval is divided into as many as 16 slots. The number of slots is dependent on the selected interface rate of 128 kHz, 512 kHz, or 1024 kHz. The corresponding number of slots for these interface rates is 1, 2, 4, 8, and 16, respectively. Transmit and receive PCM data from an SCO channel is always mapped to the same slot. The PCM data output driver tristates its output on unused slots to allow other devices to share the same PCM interface signals. The data output driver tristates its output after the falling edge of the PCM clock during the last bit of the slot. The BT850 -Sx supports both short - and long -frame synchronization in both master and slave modes. In short -frame synchronization mode, the frame synchronization signals 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 b it clock and expects the first bit of the first slot to start at the next rising edge of the clock.

The I2S interface supports both master and slave modes. The I2S signals are: ▪ I2S clock: I2S SCK ▪ I2S Word Select: I2S WS ▪ I2S Data Out: I2S SDO ▪ I2S Data In: I2S SDI I2S SCK and I2S WS become outputs in master mode and inputs in slave mode, while I2S SDO always stays as an output. The channel word length is 16 bits and th e data is justified so that the MSB of the left -channel data is aligned with the MSB of the I2S bus, per the I 2S specification. The MSB of each data word is transmitted one bit clock cycle after the I 2S WS transition, synchronous with the falling edge of b it clock. Left-channel data is transmitted when I 2S WS is low, and right -channel data is transmitted when I2S WS is high. Data bits sent by the BT850 are synchronized with the falling edge of I2S_SCK and should be sampled by the receiver on the rising edge of I2S_SSCK. The clock rate in master mode is either of the following: 48 kHz x 32 bits per frame = 1.536 MHz 48 kHz x 50 bits per frame = 2.400 MHz The master clock is generated from the input reference clock using a N/M clock divider. In the slave mode, any clock rate is supported to a maximum of 3.072 MHz. Timing values specified in Table 17 are relative to high and low threshold levels.

Figure 11: Power on reset (POR) timing When the system requires a reset , you must hold the rest line in low state for longer than 3.96 milliseconds to complete the reset cycle. WARNING An improper low state on the reset line (such as a voltage glitch) causes a system error due to a crash on the EEPROM content. A bypass cap such as 0.1uF placed on the reset line overcomes the issue caused by the glitch.

All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 Checklist (for PCB): ▪ MUST locate the BT850 module close to the edge of PCB. ▪ Use solid GND plane on inner layer (for best EMC and RF performance). ▪ Place GND vias close to module GND pads as possible ▪ Route traces to avoid noise being picked up on VCC supply. ▪ Antenna Keep-out area: – Ensure there is no copper in the antenna keep-out area on any layers of the host PCB. – Keep all mounting hardware and metal clear of the area to allow proper antenna radiation. – For best antenna performance, place the BT850 module on the edge of the host PCB, preferably in the corner with the antenna facing the corner. – A different host PCB thickness dielectric will have small effect on antenna. Figure 16: Recommend antenna keep-out area (in blue) used on the BT850 Checklist (for metal/plastic enclosure): ▪ Minimum safe distance for metals without seriously compromising the antenna (tuning) is 40 mm top/bottom and 30 mm left or right. ▪ Metal close to the BT850-SA chip monopole antenna (bottom, top, left, right, any direction) will have degradation on the antenna performance. The amount of degradation is entirely system-dependent which means some testing by customers is required (in their host application). ▪ Any metal closer than 20 mm starts to significantly degrade performance (S11, gain, radiation efficiency). ▪ It is best that the customer tests the range with mock-up (or actual prototype) of the product to assess effects of enclosure height (and material, whether metal or plastic).
