XR16V564DIV-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V564DIV-F is a quad universal asynchronous receiver/transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.25 V to 3.6 V and supports data rates up to 16 Mb/s. The device features 32-byte transmit and receive FIFOs for each channel, enhancing throughput efficiency. It is housed in a 64-lead Low Profile Quad Flat Package (LQFP) with dimensions of 10 mm x 10 mm. The component is rated for an industrial operating temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates four independent UART channels with 32-byte FIFO buffers per channel to minimize CPU intervention.
• Supports high-speed serial communication with maximum data rates reaching 16 Mb/s.
• Compatible with low-voltage power supplies ranging from 2.25 V to 3.6 V.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multiple serial connections
• Embedded control units with limited CPU overhead
• Telecommunications equipment utilizing RS-232 or RS-485 protocols

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'DIV' confirms the LQFP-64 package and industrial temperature grade during sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check for recent product discontinuation notices as some variants in this series have reached end-of-life status. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent serial ports are required within a single IC footprint. Compare against the XR16V554DIV-F if only 16-byte FIFOs are sufficient, or the XR16V654DIV-F if higher voltage tolerance is needed. Verify that the 2.25 V to 3.6 V supply range aligns with the system's power architecture. Consider the 16 Mb/s speed limit for high-bandwidth applications.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16V5xxD family of quad UARTs from MaxLinear. It shares architectural similarities with the XR16V554 and XR16V654 models but distinguishes itself through its specific 32-byte FIFO depth and 16 Mb/s data rate capability. The family is designed for cost-effective multi-port serial expansion in compact electronic designs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16V564DIVTR-F is a tape-and-reel version of the same die and functionality. Direct pin-to-pin replacements may include the XR16V554DIV-F or XR16V654DIV-F, though FIFO sizes and voltage ranges differ. Verify electrical specifications before substitution.
