XR16V698IQ100TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V698IQ100TR-F is a quad universal asynchronous receiver/transmitter (UART) interface integrated circuit manufactured by MaxLinear. It provides four independent UART channels within a single package, supporting data rates up to 3 Mbps. The device operates on a single 3.3 V power supply and features a 16-byte FIFO buffer for each channel to enhance throughput efficiency. It supports standard RS-232 signaling levels and includes hardware flow control signals such as RTS, CTS, DSR, and DCD. The component is housed in a 48-pin LQFP package and is rated for industrial temperature ranges from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix IQ100TR-F against the official MaxLinear datasheet to confirm pinout compatibility and thermal specifications. Ensure that the 3.3 V operating voltage aligns with the target system's power rails. Check for any recent product change notifications or end-of-life notices directly from the manufacturer before finalizing procurement plans.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires four distinct UART interfaces without consuming excessive board space. Compare the 16-byte FIFO depth against application latency requirements. Confirm that the 48-pin LQFP package fits the available footprint constraints. Evaluate if the fixed 3.3 V operation meets the system's voltage regulation capabilities compared to wider voltage range alternatives.
