PAN1740A Series

Bluetooth® 5 Low Energy RF Module

The PAN1740A Series RF Module is Panasonic’s next-generation, optimized version of the existing PAN1740 Series Module, offering a reduced boot time and supporting up to eight (8) connections to allow greater flexibility to create more advanced applications.


The PAN1740A Series has a fully integrated radio transceiver and baseband processor for Bluetooth® 5.0 Low Energy. It can be used as a standalone application processor or as a data pump in hosted systems. The PAN1740A 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/I2S and a Sample Rate Converter unit.


The Bluetooth Low Energy 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 5.0 Standard.  

The PAN1740A Series has dedicated hardware for the Link Layer implementation of Bluetooth Low Energy and interface controllers for enhanced connectivity capabilities.


The predecessor PAN1740 Series shares the same small form factor footprint and is compatible in the SDK.

FCC, IC and CE approval are under preparation.
