Overview
The TL16C550CIPT, produced by Texas Instruments, is a functional upgrade of the TL16C550B asynchronous communications element (ACE), which itself is an upgrade of the TL16C450. This component is designed to handle serial-to-parallel and parallel-to-serial conversions, making it a versatile tool for various communication applications. It operates in both TL16C450 mode and an alternate FIFO mode, significantly reducing software overhead by buffering received and transmitted characters. The TL16C550CIPT includes advanced features such as programmable auto-RTS and auto-CTS, modem control capabilities, and a fully prioritized interrupt system.
