Product Summary
The TL16C552AFN is an enhanced dual-channel asynchronous communications element (ACE). The device serves two serial input/output interfaces simultaneously in microcomputer or microprocessor-based systems. Each channel of the TL16C552AFN 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 TL16C552AFN can be read at any time during functional operation by the CPU. The information obtained includes the type and condition of the transfer operations being performed and the error conditions encountered. In addition to its dual communications interface capabilities, the TL16C552AFN provides the user with a bidirectional parallel data port that fully supports the parallel Centronics-type printer interface.
