ST16C654DCQ64TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C654DCQ64TR-F is a quad Universal Asynchronous Receiver and Transmitter (UART) manufactured by MaxLinear. It integrates 64 bytes of transmit and receive FIFOs for each channel, supporting data rates up to 1.5 Mbps. The device operates within a supply voltage range of 2.97 V to 5.5 V and is housed in a 64-LQFP surface-mount package with dimensions of 10x10 mm. It supports Intel and Motorola bus interfaces and includes automatic flow control capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad UART architecture with dedicated 64-byte transmit and receive FIFOs per channel
• Supports high-speed asynchronous serial communication at data rates up to 1.5 Mbps
• Compatible with both Intel and Motorola bus interface protocols

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multiple serial ports
• Telecommunications equipment utilizing RS-232 or similar protocols
• Embedded controllers needing expanded asynchronous I/O capabilities

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix TR-F indicates tape-and-reel packaging when sourcing components. Confirm that the DC variant corresponds to the commercial temperature range of 0°C to +70°C as documented in official specifications. Ensure compatibility with existing board layouts for the 64-LQFP footprint before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART channels are required with deep buffering to handle burst data traffic. The 64-byte FIFO depth reduces CPU intervention compared to standard 16-byte implementations. Verify that the operating environment remains within the commercial temperature limits and that the 2.97V to 5.5V supply range matches the system power design.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C654 series of quad UARTs from MaxLinear. It shares functional similarities with the ST16C554 but offers increased FIFO capacity. The DCQ64 designation specifies the commercial temperature grade and LQFP-64 package type, distinguishing it from industrial variants or different package options like PLCC.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The ST16C654DCQ64-F is a pin-compatible alternative differing primarily in bulk packaging rather than electrical function. Other members of the ST16C654 family may serve as substitutes if temperature ranges or package styles align with the application requirements.
