nRF52820 系統單晶片(SoC)

內建USB的藍牙5.2 SoC，支援低功耗藍牙、藍牙Mesh網狀網路、Thread和Zigbee

nRF52820是一款系統單晶片(SoC)，小小封裝提供USB和高階無線連接功能，可用於人機介面裝置、智慧家居、商業和工業應用。

nRF52820採用Arm Cortex-M4處理器，主頻為64 MHz。它有256 KB 快閃記憶體和32 KB RAM，以及一系列類比/數位介面，如類比比較器、UART、SPI、TWI、QDEC，最後還有重要的USB介面。

nRF52820可接受1.7-5.5 V的電源，比如可充電電池或者USB供電。2.4 GHz多協定無線通訊功能齊備，最多可提供8 dBm輸出功率。

nRF52820支援所有低功耗藍牙的功能，包括測向、2 Mbps高傳輸量、長距離和所有藍牙5.2功能。它還支援藍牙Mesh網狀網路、Thread和Zigbee Mesh網狀網路協定。

nRF52820的USB週邊設備實現全速USB 2.0，可提供廣泛使用的介面，與PC、平板電腦、智慧手機和閘道器等一系列主機進行低延遲、高頻寬通訊。nRF52820還增加了透過USB進行裝置韌體更新(DFU)的選項。當連接到USB主機時，nRF52820可以採用始終存在的5 V VBUS訊號直接供電，Downloads(下載)為該設定提供了參考布板。

nRF52833 DK是推薦的開發套件，它可以進行nRF52820元件模擬，並且可以作為轉移至客製電路板進行開發之前的上手工具。

nPM1300 PMIC

Power Management IC (PMIC) with unique system management features

The nPM1300 is designed to provide highly efficient power regulation for Nordic’s nRF52 and nRF53 Series, as well as the nRF54L and nRF54H Series wireless multiprotocol Systems-on-Chip (SoC). The PMIC is also suitable for battery charging for applications based on the nRF91 Series systems-in-package (SiPs) for cellular IoT, by using the PMIC’s unregulated output to power the SiP's internal buck regulators.

Devices using the nPM1300 and a compatible SoC or SiP also get access to the Nordic Fuel Gauge, a highly accurate, ultra-low-power way of estimating state-of-charge of rechargeable batteries.

nPM1100 PMIC

Ultra-small form-factor Power Management IC (PMIC) for charging batteries and power delivery

The nPM1100 is a dedicated power management IC (PMIC) with dual-mode configurable buck regulator and integrated battery charger. It is designed as a complementary component to Nordic’s nRF52® Series and nRF53® Series System-on-Chips (SoCs) to ensure reliable power delivery and stable operation, whilst maximizing battery life through high efficiency and low quiescent currents. It can also be used as a generic PMIC device for any other suitable application. Its extremely compact form factor makes it ideal for advanced wearables, connected medical devices, and other size constrained applications. PCB area usage can be as low as 23 mm2.
