nRF52805 系統單晶片

專為小型雙面PCB板設計最佳化的WLCSP封裝藍牙5.2 SoC

nRF52805系統單晶片(SoC)是業界領先的nRF52系列中的一員。它是一款採用WLCSP封裝的系統單晶片，專為小型雙面PCB板設計最佳化，非常適於成本受限的應用。它是信標、拋棄式醫療裝置、感測器、觸控吗筆和簡報器等應用的完美選擇。

nRF52805採用時脈頻率為64 MHz的Arm® Cortex®-M4處理器。內建192 KB Flash和24 KB RAM，並整合一系列類比/數位介面，如2通道12位ADC、SPI、UART、TWI和QDEC。

nRF52805是一款藍牙5.2 SoC，支援低功耗藍牙和2.4 GHz專有協定。2 Mbps高傳輸量，傳送資料更快、更高效；藍牙通道選擇演算法#2 (CSA #2)，改善共存，減少干擾。它還支援2.4 GHz專有協定。無線訊號具有高達4 dBm 的發射功率和-97 dBm靈敏度(1 Mbps低功耗藍牙)。

nRF52805可選擇我們最小的2.48x2.46 mm WLCSP封裝，專為雙層PCB板設計最佳化。這使得設計更精巧、成本更低。通常設計方面需要權衡，因為精巧型設計通常需要四層PCB，而這又帶來明顯更高的成本。我們提供9.5x8.8 mm的參考版圖設計，所有10個GPIO均可使用，只需要10個外部無源元件(包括兩個晶體負載電容)。

nRF52 DK是推薦的開發板，它可以進行nRF52805元件模擬，並且可以作為轉移至定製電路板進行開發之前的練手工具。

nPM1300 PMIC

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 nRF54H20 advanced 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.
