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.
