Description

The TL16C2550 is a dual universal asynchronous receiver and transmitter (UART). It incorporates the functionality of two TL16C550D UARTs, each UART having its own register set and FIFOs. The two UARTs share only the data bus interface and clock source, otherwise they operate independently. Another name for the uart function is Asynchronous Communications Element (ACE), and these terms will be used interchangeably. The bulk of this document describes the behavior of each ACE, with the understanding that two such devices are incorporated into the TL16C2550.

Each ACE is a speed and voltage range upgrade of the TL16C550C, which in turn is a functional upgrade of the TL16C450. Functionally equivalent to the TL16C450 on power up or reset (single character or TL16C450 mode), each ACE can be placed in an alternate FIFO mode.
