Panasonic Industry PAN1781 Bluetooth Low Energy Module

Space- and cost-saving Bluetooth Low Energy module includes Arm Cortex-M4 MCU

Panasonic Industry has introduced an integrated wireless module which provides Bluetooth® Low Energy connectivity as well as running the host system’s application software.

 

The new PAN1781 is fully compliant with the Bluetooth 5.1 specification. Based on the Nordic Semiconductor nRF52820 single-chip radio controller, the PAN1781 offers a maximum data-transfer rate of 2 Mbits/s using the high-speed LE 2M PHY, or substantially longer range using the LE coded PHY at a data rate of 500 kbits/s or 125 kbits/s.

 

The Bluetooth channel selection algorithm improves performance in environments subject to high interference. The new advertising extensions in the Bluetooth Low Energy specification allow large amounts of data to be broadcast in connectionless scenarios.

 

Featuring a 64 MHz Arm® Cortex®-M4 processor core, the PAN1781 provides 32 kbytes of RAM and 256 kbytes of Flash memory. This means it can be used in stand-alone mode, without an external processor, reducing the complexity of the board design, saving space and minimizing system costs.

 

The PAN1781 supports angle of arrival (AoA) and angle of departure (AoD) direction-finding using Bluetooth connectivity.

 

The PAN1781’s surface-mount package measures 15.6 mm x 8.7 mm x 2.1 mm. Its outline is the same as that of the Panasonic Industry PAN1780 Bluetooth Low Energy module. It is also a drop-in replacement for the PAN1026A and PAN1762 modules.

 

The PAN1781 has the orderable part number ENW89857A1KF.
