UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C554DCQ64TR-F is a quad Universal Asynchronous Receiver and Transmitter (UART) featuring 16-byte transmit and receive FIFOs. It supports data rates up to 1.5 Mbps at 5V and 500 Kbps at 3.3V, operating within a supply voltage range of 2.97V to 5.5V. The device integrates four independent UART channels with selectable Intel or Motorola bus interfaces via the 16/68# pin. It includes programmable baud rate generators, internal loopback for diagnostics, and continuous interrupt output capability.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm the manufacturer designation as MaxLinear, Inc., noting that Exar Corporation was the original developer. Ensure the component matches the 64-lead LQFP package specifications and operates within the specified temperature range.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this variant over the ST16C554CQ64 if continuous interrupt output is required without software configuration. Verify compatibility with the host processor's bus interface mode, as the 64-pin package restricts operation to Intel mode only. Ensure the system clock frequency supports the desired baud rate generation requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the ST16C554D series, which combines features of the 16C554 and 68C554 on a single chip. It is pin-to-pin compatible with industry standards like the TL16C554A and SC16C554B. The DC suffix specifically denotes the 64-lead LQFP package with continuous interrupt functionality.
