16C550 - TL16C550

Datasheet Summary

Description

The TL16C550A is a functional upgrade of the TL16C450 asynchronous communications element (ACE).

Functionally identical to the TL16C450 on power up (character mode†), the TL16C550A can be placed in an alternate mode (FIFO) to relieve the CPU of excessive software overhead.

Features

  • tive (high or low respectively) while the ACE is selected, the CPU is allowed to read status information or data fro.
