Overview
The PAN1740A is an optimized version of the PAN1740, offering a reduced boot time and
supporting up to eight connections. It has a fully integrated radio transceiver and baseband
processor for Bluetooth 5 LE. It can be used as a stand-alone application processor or as a data
pump in hosted systems. The device is optimized for remote control units (RCU) requiring
support for voice commands and motion/gesture recognition. Its integrated Audio Unit (AU)
offers easy interface for MEMS microphones over PDM, external codecs over PCM/I
2
S, and a
Sample Rate Converter unit. The Bluetooth LE firmware includes the L2CAP service layer
protocols, Security Manager (SM), Attribute Protocol (ATT), the Generic Attribute
Profile (GATT), and the Generic Access Profile (GAP). All profiles published by the Bluetooth
SIG as well as custom profiles are supported. The transceiver interfaces directly to the antenna
and is fully compliant with the Bluetooth 5 standard. The PAN1740A has dedicated hardware for
the Link Layer implementation of Bluetooth LE and interface controllers for enhanced
connectivity capabilities.
