ST16C654IQ100-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C654IQ100-F is a quad universal asynchronous receiver-transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features four independent UART channels, each equipped with 16-byte transmit and receive FIFOs to enhance data throughput and reduce CPU overhead. The device supports dual bus compatibility, adhering to both Intel and Motorola bus protocols for flexible system integration. It operates within a supply voltage range of 2.97V to 5.5V and is rated for an industrial temperature range of -40°C to +85°C. The component is housed in a 100-lead LQFP package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad channel architecture with dedicated 16-byte FIFOs per channel
• Dual bus protocol support for Intel and Motorola compatibility
• Wide operating voltage range accommodating 3.3V and 5V systems

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation control systems requiring multiple serial ports

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'F' against official MaxLinear documentation to confirm exact packaging or environmental compliance details. Confirm current availability status as distribution listings may indicate end-of-life or limited stock conditions. Ensure the 100-lead LQFP footprint matches the target PCB design constraints before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires four independent UART interfaces with hardware flow control and FIFO buffering. Compare against single-channel alternatives if pin count allows reduction. Verify that the 100-lead package size fits the mechanical enclosure. Ensure the operating voltage requirements align with the 2.97V to 5.5V specification range.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C654 series of quad UART controllers. It shares functional similarities with other members like the ST16C554DIQ64 but differs in package density and lead count. The series is designed for applications demanding robust serial communication capabilities in compact form factors.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct pin-to-pin replacements within the same MaxLinear family. Evaluate cross-manufacturer equivalents such as the Texas Instruments 16C654 variants, ensuring FIFO depth and bus protocol support match the original design requirements.
