Datasheet Details

Part number:

D16550

Manufacturer:

Lattice Semiconductor

File Size:

281.08 KB

Description:

Configurable UART

Features

* Software compatible with 16450 and 16550 UARTs Configuration capability Separate configurable BAUD clock line Two modes of operation: UART mode and FIFO mode Majority Voting Logic In the FIFO mode transmitter and receiver are each buffered with 16 byte FIFO to red

Applications

* with area limitation and where the UART works only in 16450 mode, disabling Modem Control and FIFO's allow to save about 50% of logic resources. The D16550 has universal microcontroller interface, allows correct communication with D16550 no matter how D16550 clock is related to microcontroller clock
