PAN1781 Module with nRF52820 SoC to Support Bluetooth Direction Finding and Long Range for Battery-Powered Devices

Nordic Semiconductor has announced that Panasonic has selected its nRF52820 Bluetooth 5.2/ LE multiprotocol SoC to power its ‘PAN1781’ module. This SoC features 64MHz, 32-bit Arm Cortex M4 processor and 256kB Flash and 32kB RAM memory allocation which ensures that the module can support a wide variety of Industrial Internet of Things (IIoT) applications. The nRF52820 SoC enables the PAN1781 module to take advantage of Bluetooth 5’s high throughput (2Mbps) and Long Range, and Bluetooth 5.1’s Direction Finding and Angle-of-Departure technology across IoT applications including smart cities, smart buildings, smart lighting, and healthcare.

The PAN1781 Module is qualified over the full industrial –40º to 85º C operating temperature range and is certified for CE RED, FCC, and ISED. It supports Bluetooth mesh, Thread, and Zigbee protocols, and has a low idle sleep current of 1.5µA. The module also integrates an external 32kHz crystal oscillator to achieve temperature stability over time as well as the higher precision required for optimizing power consumption.  

Moreover, the SoC’s Arm Cortex M4 processor and, Flash and RAM memory allocation make the PAN1781 module a single-chip option, eliminating the need for an external processor, saving complexity, space, and cost for developers.
