SAB82525H屬于集成電路（IC）的專用。由英飛凌科技股份公司制造生產(chǎn)的SAB82525H專用該系列產(chǎn)品可提供所需的功能，用以將信息源/信宿連到各種復(fù)雜或范圍狹窄應(yīng)用中的傳感器、變送器、致動(dòng)器、傳輸介質(zhì)或其他此類端點(diǎn)。例如，汽車安全氣囊驅(qū)動(dòng)器、車身控制和信息娛樂總線、自適應(yīng)電纜均衡器、智能卡等等。

General Information

The SAB 82525 is a High-Level Serial Communication Controller compatible to the SAB 82520

HSCC with extended features and functionality (HSCX). The SAB 82526 is pin and software compatible to the SAB 82525, realizing one HDLC channel (channel B). The HSCX has been designed to implement high-speed communication links using HDLC protocols and to reduce the hardware and software overhead needed for serial synchronous communications.
