Overview
The TL16C750IPM, produced by Texas Instruments, is an asynchronous communications element (ACE) that offers significant enhancements over its predecessors, such as the TL16C450 and TL16C550C. This component is designed to manage serial communications efficiently, reducing the software overhead on the CPU. It features 64-byte FIFOs for both the receiver and transmitter, along with autoflow control capabilities to manage serial data flow automatically. The TL16C750IPM is pin-to-pin compatible with the TL16C550B/C, making it a versatile upgrade for existing systems. It includes complete modem control functions and a programmable baud rate generator, supporting up to 1-Mbaud serial rates with a 16-MHz clock input.
