PC16552DVX/NOPB

Overview

The PC16552DVX/NOPB is a dual universal asynchronous receiver/transmitter (DUART) fabricated using M2CMOS technology. It features two independent serial channels, each equipped with 16-byte transmitter and receiver FIFOs to reduce CPU overhead. The device supports baud rates up to 1.5 Mbps via programmable baud generators that divide an input clock by divisors from 1 to 65,535. It operates on a single 5V supply within a temperature range of -40°C to +85°C. The component utilizes a 44-pin PLCC package for surface-mount installation.

Feature Summary

Dual independent UART channels with integrated 16-byte FIFOs
Programmable baud rate generation supporting up to 1.5 Mbps
Full modem control capability including CTS, RTS, DSR, DTR, RI, and DCD signals
Compatible with standard 16450 register sets in non-FIFO mode

Applications

Industrial communication systems requiring high-speed serial data transfer
Embedded controllers needing multiple independent serial ports
Modem interface circuits with full hardware flow control

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and environmental compliance. Confirm availability status as this part number may be subject to discontinuation notices. Ensure the procurement channel provides valid traceability for the component lot.

Selection Notes

Select this component when a design requires two fully independent serial interfaces with hardware FIFO buffering. Verify that the system clock frequency allows for accurate baud rate division up to the maximum required speed. Ensure the PCB layout accommodates the 44-PLCC package dimensions and thermal requirements.

Part Context

This component belongs to the PC16552 family of dual UARTs. It serves as a functional successor to earlier single-channel UARTs by providing doubled throughput capabilities within a single integrated circuit. The device maintains backward compatibility with legacy software drivers while offering enhanced performance through onboard buffering.
