Panasonic has introduced a long-range Bluetooth 5.0 module for industrial IoT and smart home applications. The Japanese company’s Pan 1780 Bluetooth LE module is based on the Nordic nRF52840 SoC single-chip controller.
 
An output power of up to +8dBm and the sensitivity of the nRF52840 in combination with the LE coded phy make the module attractive for applications that require a long range. The Bluetooth 5.0 features enable a higher symbol rate of 2Mbit/s using the high-speed LE 2M phy.
 
Furthermore, the LE advertising extensions allow for much larger amounts of data to be broadcasted in connectionless scenarios.
 
Besides BLE5.0 with the qualified Bluetooth mesh profile stack, it supports 802.15.4 and NFC-A. With its Arm Cortex M4F processor, 256kbyte RAM and the built-in 1Mbyte flash memory, it can be used in standalone mode, thereby eliminating the need for an external processor, saving complexity, space and cost. Also available is the Pan 1780AT, a variant with additional AT command set.
 
Measuring 15.6 by 8.7 by 2.0mm, the module uses an Arm TrustZone Cryptocell 310 security core that supports a secure boot process. Also, a temperature sensor was integrated in the module. The operating temperature range is -40 to +85˚C and the supply voltage ranges from 1.7 to 5.5V.
 
Target applications include industrial IoT, devices for smart city infrastructure, industrial mesh networks or robotics within Industry 4.0 environments. Also, smart health and secure medical peripherals or building automation applications such as smart locks or intelligent lighting are suitable areas of use.
 
Thanks to the performance and the built-in Cryptocell, it is also suitable for edge computing.
 
Panasonic develops diverse electronics technologies for the consumer electronics, housing, automotive and B2B businesses. The company, which celebrated its 100th anniversary in 2018, has expanded globally and now operates 582 subsidiaries and 87 associated companies worldwide, recording consolidated net sales of US$72.10bn for the year ended March 2019.
