nRF52 Series and nRF5340 SoC
The nRF52 Series is a family of wireless multiprotocol System-on-Chips (SoCs) offering a broad selection for any product requiring Bluetooth® Low Energy, Bluetooth mesh, Thread or Zigbee
connectivity. All family members are extremely advanced and energy efficient, but have different feature sets and memory configurations.
All the SoCs integrate a powerful yet efficient 64 MHz Arm Cortex-M4 CPU, with a floating-point unit (FPU) and an instruction cache on the higher-end SoCs. Flash memory range from 192 KB to 1024 KB while RAM range from 24 KB to 256 KB.
The nRF52 Series SoCs support an extensive range of wireless protocols, offer excellent RX sensitivity and TX power up to 8 dBm. All SoCs support Bluetooth Low Energy and are capable of high-throughput 2 Mbps in addition to features introduced in Bluetooth 5.2. A selection of the devices also supports Bluetooth features such as Direction Finding and Long Range. Mesh protocols like Bluetooth mesh, Thread and Zigbee are supported, and can on the higher-end devices run concurrently with Bluetooth Low Energy. This enables smartphones to provision, commission, configure and control mesh nodes. NFC is available to wake up the devices from sleep or to securely pair out-of-band (OOB).
The nRF5340 is the world’s first wireless SoC with two Arm® Cortex®-M33 processors. The combination of two flexible processors, the advanced feature set, and an operating temperature up to 105 °C, makes it the ideal choice for LE Audio, professional lighting, advanced wearables, and other complex IoT applications.
The nRF5340 is an all-in-one SoC, including a superset of the most prominent nRF52® Series features. Features like Bluetooth® 5.3, high-speed SPI, QSPI, USB, up to 105 °C operating temperature, and more, are combined with more performance, memory and integration, while minimizing current consumption.
