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 CSR 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 CSR 8510 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.
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 BT8000 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.

4 BLOCK DIAGRAM AND DESCRIPTIONS
Figure 1: BT800 module block diagram
Main Chip: CSR8510A10 4.1
BT800 is based on CSR8510A10 dual mode chip. The chip is a single-chip radio with on chip 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 4 general purpose I/Os are available for general usage, such as Wi-Fi coexistence or
general indicators.
Antenna 4.2
Antenna is a ceramic monopole chip antenna.
Band Pass Filter 4.3
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 4.4
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.
Crystal 4.5
The embedded 26 MHz crystal is used for generating the clock for the entire module.
