H16550S: Synchronous 16550 UART with FIFO Core
Block Diagram

Overview
The H16550S is a standard UART providing 100% software compatibility with the popular Texas Instruments 16550 device. It performs serial-to-parallel conversion on data originating from modems or other serial devices, and performs parallel-to-serial conversion on data from a CPU to these devices. The H16550S can be run in either 16450- compatible character mode or in 16550- compatible FIFO mode, where an internal FIFO relieves the CPU of excessive software overhead. The H16550S core can be utilized for many communication applications including: Serial or modem computer interface, or serial interface within modems and other devices
Features
- Independently controlled transmit, receive, line status and data set interrupts
- In FIFO mode, the transmitter and receiver are each buffered with 16 byte FIFOs to reduce the number of interrupts presented to the CPU
- Adds or deletes standard asynchronous communication bits (start, stop and parity) to or from the serial data
- Capable of running all existing 16450 and 16550a software
- Programmable baud generator
