SERC816集成电路（IC）的控制器规格书PDF中文资料

SERC816属于集成电路（IC）的控制器。由意法半导体集团制造生产的SERC816控制器该系列产品主要用于在采用不同通信协议和/或信令方法的端点之间提供信息连接。示例包括将 I2C 总线连接到 UART，将 USB 连接到 I2C、SPI、以太网或 UART、以太网 MAC 和 PHY 等的器件。此外，还包括用于通过为点对点通信设计的接口建立多路连接的器件，例如 USB 集线器控制器。

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).

■ Single-chip controller for SERCOS interface

■ Real time communication for industrial control systems

■ 8/16-bit bus interface, Intel and Motorola control signals

■ Dual port RAM with 2048 word *16-bit

■ Data communications via optical fiber rings, RS 485 rings and RS 485 busses

■ Maximum transmission rate of 16 Mbaud with internal clock recovery

■ Internal repeater for ring connections

■ Full duplex operation

■ Modulation of power of optical transmitter diode

■ Automatic transmission of synchronous and data telegrams in the communication cycle

■ Flexible RAM configuration, communication data stored in RAM (single or double buffer) or transfer via DMA

■ Synchronization by external signal

■ Timing control signals

■ Automatic service channel transmission

■ Watchdog to monitor software and external synchronization signals
