PC16550DV

Overview

The PC16550DV is a single-channel Universal Asynchronous Receiver/Transmitter (UART) manufactured by Texas Instruments. It integrates 16-byte transmit and receive FIFOs to enhance data throughput and reduce CPU intervention during serial communication tasks. The device supports baud rates up to 1.5 Mbps and operates on a single 5V supply voltage. It is housed in a 40-pin Multi-Dual In-Line Package (MDIP) designed for through-hole mounting, making it suitable for legacy system integration and industrial applications requiring robust serial connectivity.

Feature Summary

Integrated 16-byte transmit and receive FIFOs minimize processor overhead
Supports standard asynchronous serial protocols with high-speed data transfer capabilities
Includes modem control signals and break generation features for comprehensive communication control

Applications

Industrial automation systems requiring reliable serial data exchange
Legacy computer interface boards and retro-computing hardware restoration
Embedded control systems utilizing through-hole PCB layouts

Procurement Notes

Verify component authenticity due to potential availability of refurbished or obsolete stock. Confirm package integrity and pin alignment before soldering. Check for RoHS compliance status as original manufacturing specifications may predate current environmental regulations. Ensure compatibility with existing 5V logic levels in the target circuit design.

Selection Notes

Select this component when a single UART channel with FIFO buffering is required for through-hole assembly. Compare against the dual-channel PC16552 variant if two independent serial ports are needed. Verify that the 40-pin MDIP footprint matches the printed circuit board layout constraints and that the 5V operating voltage aligns with the system power domain.

Part Context

This part belongs to the PC1655x family of UART controllers, which are compatible with the industry-standard 16550 architecture but include enhanced FIFO buffers. The series provides a scalable solution for serial communication needs, ranging from basic single-channel devices to complex multi-port controllers with parallel interfaces.
