The nRF5340 from Nordic Semiconductor is a Dual Processor SoC that supports Bluetooth 5.1, Bluetooth mesh, NFC, Thread & Zigbee. It has two Arm Cortex-M33 processors and supports an extensive range of wireless protocols. Arm TrustZone provides trusted execution by implementing a division between secure and non-secure Flash, RAM, peripherals, and GPIOs. The application processor of the SoC is optimized for performance and can be clocked at either 128 or 64 MHz, using voltage-frequency scaling. It has 1 MB Flash, 512 KB RAM, a floating-point unit (FPU), an 8 KB 2-way associative cache and DSP instruction capabilities. The network processor is clocked at 64 MHz and is optimized for low power and efficiency. It has 256 KB Flash and 64 KB RAM.
This all-in-one SoC features Bluetooth 5.1, high-speed SPI, QSPI, USB, up to 105°C operating temperature, and are combined with more performance, memory, and integration, while minimizing current consumption. The 0 dBm TX current of the SoC is 3.2 mA, while the RX current is 2.6 mA with an RX sensitivity of -97.5 dBm. It also supports NFC, ANT, 802.15.4 and 2.4 GHz proprietary protocols. The device is available in a 94-lead QFN package that measures 7 x 7 mm with 48 GPIOs and is ideal for professional lighting, industrial, advanced wearables, medical, smart home, asset tracking, and RTLS application.
