Panasonic Bluetooth LE module targets IoT use
December 4, 2019
Panasonic has introduced a Bluetooth 5.0 Low Energy module with fast boot time for industrial IoT and smart home applications as well as remote controls.
The Japanese company’s Pan 1740A Bluetooth module has a quicker boot time than its Pan 1740 predecessor and supports up to eight connections to increase the flexibility to create more advanced applications.
It can be used as a standalone application processor or as a data pump in hosted systems. The device is optimised for remote control units requiring support for voice commands and motion and gesture recognition.
The Bluetooth Low Energy firmware includes the L2CAP service layer protocols, security manager, attribute protocol, Gatt generic attribute profile and the Gap generic access profile. All profiles published by the Bluetooth Sig as well as custom profiles are supported.
Measuring 9.0 by 9.5 by1.8mm, the footprint is compact and includes a Dialog DA14585 board and an Arm Cortex-M0 microcontroller. Operating temperature is -40 to +85˚C and the supply voltage is 2.2 to 3.3V.
Industrial IoT applications such as connected sensors or HMIs can benefit from the fast boot time. Also, smart home and building automation devices such as lighting systems, metering applications, remote controls, trackers or smart home nodes could profit from the module’s low power consumption.
Receive sensitivity is -93dBm. Current consumption for transmit and receive is up to 4.9mA, falling to less than 1µA in sleep mode. It has 64kbyte one-time programmable memory. Interfaces include GPIO, uart, SPI+, I2C, ADC and three-axis QD.
The module is RoHS and Reach compliant, and is lead (Pb) free. Evaluation kits are available.
Panasonic operates 582 subsidiaries and 87 associated companies worldwide, recording consolidated net sales of US$72.10bn for the year ended March 2019.
