前言:
Delfino F2837xD MCU 是 C2000 MCU 創新系列推出的首款產品。該系列中所有 MCU 產品均具備引腳及軟體相容性，可提供不同的效能範圍，充分滿足從工廠自動化伺服驅動器到起重機驅動器產品系列各種不同效能需求。Delfino F2837xD MCU 與未來單核衍生產品將改變產品平台的決策制定方式，讓客戶減少軟硬體開發時間與成本。
-
有了雙 C28x 內核與雙 CLA 提供的 800 MIPS 整合效能，無需使用多個嵌入式處理器。
-
採用兩個即時控制加速器或平行加速器 (CLA) 替代主 CPU (C28x 內核) 執行要求嚴格的控制環路分析，不僅可產生額外的頻寬，還可允許主處理器重點執行系統診斷或應用管理任務。
-
採用 C28x 內核中包含的最新三角函數 (TMU) 加速器，快速執行控制函數中使用的三角函數演算法，例如通常在 FPGA 中完成的轉矩環路演算法。
-
採用 viterbi 複雜單元 (VCU II) 加速器執行振動分析，能預先測知電機故障，增強 C28x 內核的處理功能。
-
使用四個 16 位元 ADC 對多個反饋進行精確控制與監控，可改善太陽能中央反相器和高端工業 UPS 系統等工業應用中的系統精確度；
-
介面與 TI AMC1204 隔離式 sigma delta 調變器無縫連結，可降低 MCU 輸入雜訊並實現隔離式電流分流測量。
-
使用窗型比較器保護功率級免受電流故障的損壞。
-
可在最新 C2000 MCU 系列中打造不同效能等級的產品，加速產品上市時程並降低開發成本，為未來裝置提供引腳對引腳以及軟體相容型架構。
