TI TL16C2550IPFBR

内部振荡器2，DUART1.5Mbps

Overview

The TL16C2550IPFBR 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 has a TXRDY and RXRDY output that can be used to interface to a DMA controller.
