TL16C554IFNR

异步通信部件 ASYNCHRONOUS COMMUNICATIONS ELEMENT

description

The TL16C554 and the TL16C554I are enhanced quadruple versions of the TL16C550B asynchronous communications element ACE. Each channel performs serial-to-parallel conversion on data characters received from peripheral devices or modems and parallel-to-serial conversion on data characters transmitted by the CPU. The complete status of each channel of the quadruple ACE can be read at any time during functional operation by the CPU. The information obtained includes the type and condition of the operation performed and any error conditions encountered.
