nRF52840 系統單晶片(SoC)

多協定藍牙5.2 SoC,支援低功耗藍牙、藍牙Mesh網狀網路、NFC、Thread和Zigbee

nRF52840 SoC是nRF52系列中最先進的一員。它可以滿足需要協定並行效能、豐富外圍裝置和複雜應用所面臨的挑戰。它為快閃記憶體和RAM提供了充足的記憶體,而這些正是高要求應用的必備條件。

nRF52840是具有完全協定並行效能的多協定SoC。它支援低功耗藍牙、藍牙Mesh網狀網路、Thread、Zigbee、802.15.4、ANT和2.4 GHz專有協定疊構。

nRF52840基於帶有浮點單元的32位ARM® Cortex™-M4 CPU,主頻為64 MHz。內建NFC-A標籤用於簡化的配對和支付解決方案。本晶片內建ARM TrustZone® CryptoCell密碼演算法單元,可獨立於CPU高效執行密碼演算法任務。它有許多數位週邊設備和介面,如高速SPI和QSPI介面,用於連接到外部快閃記憶體和顯示器,PDM和I2S連接數位麥克風和音訊;還有一個全速USB裝置,用於資料傳送和作為電源為電池充電。

透過精密的片上自適應電源管理系統,實現了極低的功耗。
