Epson發表內嵌EPD驅動器的低耗電微處理器2010年12月20日影像產品以及半導體解決方案供應商Seiko Epson（”Epson”, TSE:6724）日前宣佈已開發出S1C17F57之樣品，這款內建驅動器的全新16位元微處理器，已針對如E Ink公司所出品的中小尺寸電子紙顯示器（EPD）之性能進行最佳化。
S1C17F57樣品已開始出貨，Epson計劃於2011年三月進行量產。
同時，Epson亦宣布其新開發的S1D14F50系列節能驅動IC已開始出貨，可協助EPD發揮最大性能。
隨著電子閱讀器（e-reader）的需求呈現爆炸性成長，EPD市場正迅速擴大中。
由於EPD具備高對比、高靈活性、影像穩定性與低耗電特性，而成為相關產品的最佳首選。
為了滿足EPD市場逐漸增長的需求，Epson開發出S1C17F57，一款擁有記憶體（ROM與RAM）、計時器及串列式介面等標準功能的微處理器。
此外，這款產品同時擁有許多嵌入式規格如即時時脈(RTC)、推論調整（theoretical regulation）、高效能區段式EPD驅動程式、以及一個溫度感測器。
因此，這個微處理器不僅可驅動顯示器，還可修正容易損害顯示品質的溫度波動，藉以將電子紙顯示器的效能推升至最大。
Epson還運用其專業的低耗電技術，成功達成極低的產品耗電量（於睡眠模式下耗電僅120 nA）。
此外，此微處理器亦能夠以厚度僅有200微米的裸晶形式出貨，對於需要長效電池壽命及纖薄型態的應用如智慧卡或其他小型行動裝置來說，是最完美的選擇。
同時，Epson也與Citizen Seimitsu共同開發一款內嵌S1C17F57的整合式電子紙顯示模組。
該公司已開始出貨其薄膜覆晶封裝（COF, Chip-on-Flex）模組，並內含一個電子紙顯示器，讓製造商更容易針對電子紙產品進行設計。
Epson Microdevices事業部副執行長宮川隆平表示：「Epson長久以來不斷針對各式電池驅動產品，提供低功耗的半導體產品。
