ST16C650ACQ48-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C650ACQ48-F is a single Universal Asynchronous Receiver/Transmitter (UART) integrated circuit manufactured by MaxLinear, Inc. It features a 16-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU overhead. The device operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 3 Mbps. It is housed in a 48-lead Thin Quad Flatpack (TQFP) package with dimensions of 7 mm x 7 mm. The component complies with the RS-232 standard and includes full modem control signals.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrated 16-byte FIFO buffers for both transmission and reception to minimize processor intervention.
• Supports high-speed asynchronous serial communication with baud rates reaching 3 Mbps.
• Includes complete hardware flow control and modem status signal management.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring reliable serial communication links.
• Embedded control units in mobile machinery and hydraulic equipment.
• General-purpose UART interfaces in compact electronic devices.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer designation as MaxLinear, Inc., noting the corporate transition from Silicon Labs. Confirm the specific suffix 'F' indicates the lead-free RoHS-compliant variant. Ensure the package type matches the 48-TQFP specification with a 7x7 mm footprint. Cross-reference the datasheet revision to confirm compatibility with required operating temperatures and voltage levels before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single-channel UART with moderate FIFO depth is required for 3.3 V or 5 V logic systems. It serves as a direct replacement for legacy ST16C650 designs. Consider the TQFP48 package constraints for PCB layout. Verify that the 3 Mbps maximum baud rate meets the application's timing requirements compared to higher-speed alternatives.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C650 family of single UART controllers. It shares functional similarities with the ST16C1551 but differs in FIFO capacity and pin configuration. The ST16C650ACQ48-F is specifically designed for applications needing robust RS-232 connectivity without the complexity of multi-channel controllers. It is widely used in industrial and commercial embedded systems.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should verify pin-to-pin compatibility with other ST16C650 variants or equivalent single-channel UARTs from different manufacturers based on electrical specifications.
