SERC816屬于集成電路（IC）的控制器。由意法半導體集團制造生產(chǎn)的SERC816控制器該系列產(chǎn)品主要用于在采用不同通信協(xié)議和/或信令方法的端點之間提供信息連接。示例包括將 I2C 總線連接到 UART，將 USB 連接到 I2C、SPI、以太網(wǎng)或 UART、以太網(wǎng) MAC 和 PHY 等的器件。此外，還包括用于通過為點對點通信設計的接口建立多路連接的器件，例如 USB 集線器控制器。

GENERAL DESCRIPTION

The SERCOS interface controller SERCON816 is an integrated circuit for SERCOS interface communication systems. The SERCOS interface is a digital interface for communication between systems which have to exchange information cyclically at short, fixed intervals (62,5 s to 65 ms). It is appropriate for the synchronous operation of distributed control or test equipment (e.g. connection between drives and numeric control).
