Product Summary

The PC16550DV is a Universal Asynchronous Receiver/Transmitter with FIFOs. The PC16550DV can be put into an alternate mode (FIFO mode) to relieve the CPU of excessive software overhead.

Parametrics

PC16550DV absolute maximum ratings: (1)Temperature Under Bias: 0℃ to +70℃; (2)Storage Temperature: -65℃ to +150℃; (3)All Input or Output Voltages with Respect to VSS: -0.5V to +7.0V; (4)Power Dissipation: 1W.

Features

PC16550DV features: (1)Capable of running all existing 16450 software; (2)After reset, all registers are identical to the 16450 register set; (3)Adds or deletes standard asynchronous communication bits (start, stop, and parity) to or from the serial data; (4)Holding and shift registers in the 16450 Mode eliminate the need for precise synchronization between the CPU and serial data; (5)Independently controlled transmit, receive, line status, and data set interrupts.
