Wearables
Wearables encompass a broad variety of products that inhabit our person gathering data and feeding data back to us for all sorts of different purposes.
“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 LE 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 nRF52810 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. Application development is supported by the S132 SoftDevice, supporting up to 20 concurrent links in any combination of roles, and the nRF5 SDK.
The nRF52810 SoC is sampling now to selected customers. The SoC comes in either a 6x6mm 48-pin QFN package with 32 GPIOs, or a 5x5mm 32-pin QFN with 16 GPIOs. Key features include: 64MHz, 32-bit ARM Cortex M4 MCU, 2.4GHz multiprotocol radio with 96dBm sensitivity (at 1Mbps), 196kB Flash / 24kB RAM, ADC and analog comparator; 1 x PDM digital mic input; 1 x 4-channel PWM; 1x SPI, 1 x I2C, 1 X UART; 1 x QDEC; +4 dBm (max) output power, 4.6mA peak TX at 0dBm, 4.6mA peak RX.
