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 Low Energy (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.
