1 SCOPE
This document describes key hardware aspects of the Laird BT800 Bluetooth HCI/HID module. This document is
intended to assist device manufacturers and related parties with the integration of this module into their host
devices. Data in this document are drawn from a number of sources including data sheets for the CSR8510.
Because the BT800 is currently in development stage, this document is preliminary and the information in this
document is subject to change. Please contact Laird Technologies or visit the Laird website at
www.Lairdtech.com to obtain the most recent version of this document.
2 OPERATIONAL DESCRIPTION
The BT800 series of USB HCI devices are designed to meet the needs of OEMs adding robust
Bluetooth connectivity and using embedded Bluetooth stacks within these products.
Leveraging the market-leading CSR8510 chipset, the BT800 series provides exceptionally
low power consumption with outstanding range. Supporting the latest Bluetooth v4.0
Specification with EDR (Enhanced Data Rate), the Laird BT800 series enables OEMs to
accelerate their development time for leveraging either Classic Bluetooth or Bluetooth Low
Energy (BLE) into their operating system based devices.
With a tiny footprint as small as 8.5 x 13 mm, yet output power at 8 dBm, these modules
are ideal for applications where designers need high performance in minimal size. For
maximum flexibility in systems integration, the modules are designed to support a full
speed USB interface plus GPIO and additionally I2S and PCM audio interfaces.
BT800 module
BT820 USB dongle
These modules present an HCI interface and have native support for Windows and Linux Bluetooth software
stacks. All BT800 series devices are fully qualified as Bluetooth Controller Subsystem products. This also allows
designers to integrate their existing pre-approved Bluetooth Host and Profile subsystem stacks to gain a
Bluetooth END product approval for their products.
The BT800 series is engineered to provide excellent RF performance with integrated antenna and additional
band pass filters. It further reduces regulatory and testing requirements for OEMs and ensures a hassle free
development cycle. As an additional benefit of the BT800 series, Laird has implemented CSR’s HID (Human
Interface Device) Proxy Mode enabling out of the box HID connectivity for pointing devices and / or keyboard
functionality, requiring zero host device software or configuration.
A fully featured, low-cost developer’s kit is available for prototyping, debug, and integration testing of the BT800
series modules and further reduces risk and time in development cycles.

3 BLOCK DIAGRAM AND DESCRIPTIONS
Figure 1: BT800 module block diagram
CS8510A10
(Main chip)
The BT800 is based on CSR8510A10 dual mode chip. The chip is a single-chip radio with onchip LDO regulators and baseband IC for Bluetooth 2.4 GHz systems including EDR to 3 Mbps.
Dedicated signal and baseband processing is included for full Bluetooth operation. The chip
provides SPI/PCM and USB interfaces. Up to four general purpose I/Os are available for
general use such as Wi-Fi coexistence or general indicators.
Note:
The purpose of the SPI interface is to access the module’s inner settings such as
selecting different WLAN CO-EXIST scheme and enabling HID proxy mode. The SPI
interface can also be used to put the module in RF test mode. You cannot use the
module over the SPI interface for normal operation as the main host interface.
Antenna
Band Pass
Filter
BT800 – The antenna is a ceramic monopole chip antenna.
The band pass filter filters the out-of-band emissions from the transmitter to meet the
specific regulations for type approvals of various countries.
EEPROM
There are 64 k bits EEPROM embedded on the BT800 module which can be used to store
customizable parameters, such as maximum TX power, PCM configuration, USB product ID,
USB vendor ID, and USB product description. With that, the BT800 module can support
HID/HCI Proxy mode.
The embedded 26 MHz crystal is used for generating the clock for the entire module.

8.4.2. Long Frame Sync
Figure 4: Long Frame Sync (shown with 8-bit Companded Sample)
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 the
BT800 is configured as PCM master, generating PCM_SYNC and PCM_CLK, then PCM_SYNC is eight bits long.
When the BT800 is configured as PCM Slave, PCM_SYNC is from one cycle PCM_CLK to half the PCM_SYNC rate.
BT800 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.
8.4.3. 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.
Figure 5: Short Frame Sync (Shown with 16-bit Sample)
As with Long Frame Sync, BT800 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.

8.10. PCM_CLK and PCM_SYNC Generation
BT800 has two methods of generating PCM_CLK and PCM_SYNC in master mode:


Generating these signals by DDS from BT800internal 4MHz clock. Using this mode limits PCM_CLK to 128,
256 or 512 kHz and PCM_SYNC to 8 kHz.
Generating these signals by DDS from an internal 48MHz clock, which 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.

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 SKEY_PCM_LOW_JITTER_CONFIG to 0x08080177.
8.11. PCM Configuration
Configure the PCM by using PSKEY_PCM_CONFIG32 and PSKEY_PCM_LOW_JITTER_CONFIG (See your PSKey
file). The default for PSKEY_PCM_CONFIG32 is 0x00800000 (for example: 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).
8.12. 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 13 lists these alternative functions. Figure 11 shows the timing diagram.

9 POWER CONTROL AND REGULATION
See the Example Application Schematic (Figure 19) for the regulator configuration. BT800 contains three
regulators:


USB linear regulator, to generate the 3.3 V from the USB bus power and the input to the high-voltage linear
regulator.
High-voltage linear regulator, to generate the main 1.8 V from the USB linear regulator or an external 3.3 V.
This regulator then feeds the three low-voltage regulators:
–
–
–
9.1.
Low-voltage VDD_DIG linear regulator, a programmable low-voltage regulator to supply a 0.90 V
to1.25 V digital supply, VDD_DIG.
Low-voltage VDD_ANA linear regulator, to supply the radio supply, VDD_RADIO.
Low-voltage VDD_AUX linear regulator, to supply the auxiliary supply, VDD_AUX.
USB Linear Regulator
The integrated USB LDO linear regulator is available as a 3.3V supply rail (VREG_IN_HV) and is intended to
supply the USB interface and the high-voltage linear regulator. The input voltage range supplied at
VREG_IN_USB is between 4.25V and 5.75V. VREG_IN_HV serves as both the output for the USB linear regulator
and the input to the High-voltage linear regulator. The maximum current from this regulator is 150 mA, of which
50 mA is available for external use (for example, EEPROM/LED). This regulator is internally decoupled and no
external decoupling caps are required on the VREG_IN_HV pin, however in noisy environments, an output
capacitor of 1uF to 4.7uF (+/-20%) is suggested.
This regulator is enabled by default. If the USB linear regulator is not required, leave its input (VREG_IN_USB)
unconnected and connect 3.3V to VREG_IN_HV (if using the High-voltage linear regulator), VDD_HOST,
VDD_EN_RST#, and VDD_PADS (if using 3.3V I/O).
9.2.
High-voltage Linear Regulator
The integrated high-voltage linear regulator is available to power the main 1.8V supply rail including the three
internal low-voltage linear regulators VDD_DIG, VDD_ANA, and VDD_AUX. The input voltage range supplied at
VREG_IN_HV is between 2.3V and 4.8V. VREG_OUT_HV serves as both the output to the high-voltage linear
regulator and the input to the internal low voltage regulators. The maximum current from this regulator is 100

mA; this regulator is not available for external use. This regulator is internally decoupled and no external
decoupling caps are required on the VREG_IN_HV pin, however in noisy environments, an output capacitor of
1uF to 4.7uF (+/-20%) is suggested.
If this regulator is not required, and the USB linear regulator is not used then leave VREG_IN_HV unconnected
and connect 1.8V to VREG_OUT_HV.
9.3.
Voltage Regulator Enable and Reset
A single pin, VREG_EN_RST#, controls both the regulator enables and the digital reset function. All the regulators
are enabled, except the USB linear regulator, by taking the VREG_EN_RST# pin above 1 volt. Software also
controls the regulators. The VREG_EN_RST# pin is connected internally to the reset function and is powered
from VDD_HOST, so do not apply voltages above VDD_HOST to the VREG_EN_RST# pin. The REG_EN_RST# pin is
pulled down internally before the software starts. The VREG_EN_RST# pin is an active low reset. Assert the reset
signal for a period >5 ms to ensure a full reset.
Note:
The regulator enables are released as soon as VREG_EN_RST# is low, so the regulators shut down.
Therefore do not take VREG_EN_RST# low for less than 5 ms, as a full reset is not guaranteed.
Other reset sources are:


Power-on reset
Via a software-configured watchdog timer
A warm reset function is also available under software control. After a warm reset the RAM data
remains available.
9.4.
Power Sequencing
CSR recommends that all power supplies are 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 regardless of the reset state.

12 IMPLEMENTATION NOTE
12.1. PCB Layout on Host PCB
Checklist (for PCB):





MUST locate the BT800 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 BT800 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 18: Recommend Antenna keep-out area (in White) used on the BT800
12.1.1. Antenna Keep-out and Proximity to Metal or Plastic
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 BT800 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).



Using USB bus power (5V±10%)
Apply USB bus power (5V ±10%) directly to the Pin-7 (VREG_IN_USB) and pull-high on Pin-8
(VREG_EN_RST#) to turn on the internal regulator. The BT800 module generates 3.3 V/1.8 V output on Pin9 (VREG_IN_HV)/Pin-10 (VREG_OUT_HV) that can supply to the other DC pin of the board.
Using DC power 3.3 V
Leave the Pin-7 (VREG_IN_USB) no connection, power the on Pin-9 (VREG_IN_HV) with 3.3 V and pull-high
on Pin-8 (VREG_EN_RST#) to turn on the internal regulator. The BT800 module generates 1.8 V output on
Pin-10 (VREG_OUT_HV) which can supply to the other DC pin of the board.

Datasheet
As long as the conditions above are met, further transmitter testing is typically not required. However, the OEM
integrator is still responsible for testing its end-product for any additional compliance requirements required
with this module installed, such as (but not limited to) digital device emissions and PC peripheral requirements.
IMPORTANT:
In the event that the conditions above cannot be met (for example certain device configurations
or co-location with another transmitter), then the FCC authorization is no longer considered valid
and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator
will be responsible for re-evaluating the end product (including the transmitter) and obtaining a
separate FCC authorization.
When using Laird’s FCC grant for the BT800, the integrator must include specific information in
the user’s guide for the device into which the BT800 is integrated. The integrator must not
provide information to the end user regarding how to install or remove this RF module in the
user’s manual of the device into which the BT800 is integrated. The following FCC statements
must be added in their entirety and without modification into a prominent place in the user’s
guide for the device into which the BT800 is integrated:
IMPORTANT NOTE: To comply with FCC requirements, the BT800 must not be co-located or
operating in conjunction with any other antenna or transmitter.

Laird Customer Declaration ID Procedure
This procedure assumes that the member is simply combining two subsystems to create a new design, without
any modification to the existing, qualified subsystems. This is achieved by using the Listing interface on the
Bluetooth SIG website. Figure 26 shows the basic subsystem combination of a controller and host subsystem.
The Controller provides the RF/BB/LM and HCI layers, with the Host providing L2CAP, SDP, GAP, RFCOMM/SPP
and any other specific protocols and profiles existing in the Host subsystem listing. The design may also include a
Profile Subsystem.
