TC35668IXBG
SINGLE CHIP CONTROLLER WITH DSP
FOR BLUETOOTH V4.0 HANDSFREE SYSTEMS
The TC35668IXBG is a highly integrated RFCMOS
Bluetooth device which supports Bluetooth Classic
(3.0+EDR) and Bluetooth Low Energy (LE) 4.0
standard. The device also contains an application
MCU core, plus a built-in high performance DSP
(Digital
Signal
Processor)
for
acoustic
improvements of a hands-free system, including
background noise reduction and echo cancellation.
The TC35668IXBG contains numerous built-in
profiles that enable the device to access a mobile
handset, allowing functions such as SIM/phone
book access, audio streaming and hands-free
speech.
Toshiba has tested the Bluetooth
interoperability extensively. All Toshiba Bluetooth
devices and software are Bluetooth Qualification
Body (BQB) qualified.
