前言：

RH850/D1x系列已將儀表控制、圖形顯示及功能安全整合至單晶片上

2015年5月13日--先進半導體解決方案之頂尖供應商瑞薩電子(TSE：6723)宣佈推出RH850/D1x系列儀表總成專用32位元車用微控制器(MCU)，可提供易於存取的資訊以帶來更安全且豐富的駕駛體驗。

連網汽車從汽車網路、攝影機及多媒體系統產生許多資訊。此趨勢帶來強烈的需求，亦即以易懂且易讀的方式，將上述大量資訊傳送給駕駛者。隨著儀表總成開始廣泛使用圖像，彩色液晶螢幕也獲得大量採用以提高顯示能力與可讀性，在適當的時機提供適當的畫面以提升與駕駛者之間的溝通，並在畫面中結合各種儀表、圖像及抬頭顯示器。

瑞薩身為全球儀表總成MCU領導供應商，運用其車用半導體之專業經驗支援整體儀表總成系統，從結合入門至中階車款的儀表控制與液晶顯示幕，到高階豪華車款所需要的全圖形化功能。RH850/D1x系列針對入門與中階汽車系統進行設計，將儀表控制、圖形顯示與功能安全性整合至單晶片上，同時降低系統物料清單(BOM)成本與可擴充的開發產品，並協助以高可靠性的彩色液晶螢幕實現儀表總成系統。

RH850/D1x MCU的主要特色：
(1) 降低系統物料清單成本
RH850/D1x MCU整合大容量RAM (最高3.5MB)以及瑞薩新開發由「Renesas Graphics Library(瑞薩繪圖程式庫)」支援的高功能性繪圖引擎。有助於降低RAM的使用量，且無需外部高速DRAM即可實現高解析度液晶螢幕顯示器。另外，藉由免除上述外部高速DRAM，即可使用低成本的四層印刷電路板來設計系統。

(2) 可擴充的開發產品
透過結合常見的基本功能，包括儀表控制與車內網路功能，瑞薩推出7種群組共計22款產品，可提供多種圖形顯示與成本的選項。如此豐富的產品種類可提供更好的軟體再利用性以及可擴充的解決方案，為儀表總成系統建立通用的平台。上述可擴充的開發產品將縮短軟體開發期間，同時降低開發與維護成本。

(3) 智慧型開發
藉由整合高功能性繪圖引擎，RH850/D1x能夠在大型螢幕上顯示高精度的動畫，以滿足中階車款的需求，同時可實現優異的表現力以及抬頭顯示器的可視性。由於RH850/D1x繪圖引擎支援OpenVG 1.1標準，HMI開發工具支援API標準，因此可更進一步縮短開發期間。

(4) 支援抬頭顯示器
RH850/D1x MCU包含可依據汽車設計(例如擋風玻璃)而自動修正視訊輸出的功能。它可使輸出的視訊資料變形以符合任何形狀，而不會造成訊框延遲。如此即可在儀表總成中加入抬頭顯示器。

(5) 功能安全
為確保儀表總成系統的功能安全，RH850/D1x MCU具備偵測系統故障的功能以及監視功能，可隨時監視並確認重要資訊皆能正確通知，例如警告與檔位等，以確保安全。

供貨時程
RH850/D1x MCU現已開始供應樣品，預定2016年4月開始量產，預估至2018年4月產能可達每月4百萬顆（供貨時程如有變更，將不另行通知。）
