Bluetooth 5 Chip Geared For Low-cost Wearables & Beacons

Nordic Semiconductor has announced new Bluetooth low energy (BLE) chip which extends the benefits of BLE 5 to simple, cost-constrained applications such as network-connected sensors and beacon building blocks for the IoT, low-cost wearables, low-cost wireless mice and keyboards for computers and tablets, toys, disposable medical monitoring devices, and basic RF remote controls.

The nRF52810 SoC further extends Nordic’s nRF52 Series of Bluetooth low energy SoCs and opens up the end-user benefits of Bluetooth 5 to even the most cost-sensitive, high-volume products and applications.

These benefits include: 2x the data bandwidth (2Mbps) compared with the Bluetooth low energy implementation of Bluetooth 4.2; and 8x the broadcasting ability with advertising extensions that increase the advertising packet payload size to 251 bytes for more efficient data transfer, particularly in beacon applications, according to the firm.

The nRF52810 SoC is a ‘subset’ of the nRF52 Series. It uses the same 100dBm link budget 2.4GHz multiprotocol radio as the nRF52832 SoC.

In addition, it incorporates a 64MHz, 32-bit ARM Cortex M4 MCU, providing similar RF performance and computational power with reduced radio energy consumption of 4.6mA respectively for Tx at 0dBm, and Rx at 1Mbps, claims the firm.

The new chip integrates 196kB Flash and 24kB RAM (compared with the nRF52832 SoC’s 512kByte Flash and 64kB RAM) which is ample to run application code typical of high-volume, low cost applications. Over-the-Air Device Firmware Updates (OTA-DFUs) of target applications is also supported.

“No matter how simple the application, any wirelessly-connected device significantly benefits from the performance benefits that Bluetooth 5 offers,” comments Geir Langeland, Nordic Semiconductor’s Director of Sales Marketing. “However, early Bluetooth 5 SoCs were too expensive to be justified for lower-level applications. Nordic has addressed that challenge with the nRF52810 SoC; this low-cost variant not only rounds out our nRF52 Series offerings but it also opens up a whole new world of possibilities for simple, cost-constrained Bluetooth low energy applications.”

“If the vision of an IoT comprising many billions of interconnected sensors is to be realized,” continues Langeland, “those sensors will not only require decent range, throughput, and security but they will also need to be inexpensive to purchase, install, and maintain. The nRF52810 SoC brings that realization a little closer.”

The SoC is compatible with the nRF52 Development Kit (DK) and application code compiled for the device is portable to all SoCs in the nRF52 Series.

The chip is supported by the S132 SoftDevice, a Bluetooth 5 pre-qualified Bluetooth low energy protocol stack.

The nRF52810 is available in 6x6mm QFN-48 and 5x5mm QFN-32 packages
