Entry-point Bluetooth 5 SoC configured for wearables/peripherals
The nRF52810 SoC is a peripheral and memory-optimized variant that Nordic positions as the most accessible, single-chip Bluetooth 5 solution available. It offers the performance metrics that come with Bluetooth 5, that include: 2x the data bandwidth (2 Mbps) 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.
The nRF52810 SoC is a ‘subset’ device of Nordic Semiconductor’s nRF52 Series (including the nRF52832 SoC with which the nRF52810 is pin-compatible, and the nRF52 Series nRF52840 SoC). The SoC uses the same 100 dBm link budget 2.4 GHz multiprotocol radio as the nRF52832 SoC, and has a 64 MHz, 32-bit ARM Cortex M4 MCU, providing similar RF performance and computational power with reduced radio energy consumption of 4.6 mA respectively for Tx at 0 dBm, and Rx at 1 Mbps. Though nRF52810 is a baseline Bluetooth 5 SoC, it integrates 196 kB Flash and 24 kB RAM (compared with the nRF52832 SoC’s 512 kByte Flash and 64 kB RAM) and is able 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.
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 SoC comes in either a 6 x 6 mm 48-pin QFN package with 32 GPIOs, or a 5 x 5 mm 32-pin QFN with 16 GPIOs. Key features include: 64 MHz, 32-bit ARM Cortex M4 MCU, 2.4 GHz multiprotocol radio with 96 dBm sensitivity (at 1 Mbps), 196 kB Flash / 24 kB RAM, ADC and analogue 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, 4.6 mA peak TX at 0 dBm, 4.6 mA peak RX.
