UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix TR-F indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as MaxLinear or its predecessor Exar, as corporate transitions may affect documentation sources. Ensure the part number matches the exact PLCC-68 form factor required for the target PCB footprint.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent serial channels are necessary within a single integrated circuit. The 64-byte FIFO depth is suitable for applications demanding reduced processor intervention during high-speed data transfers. Verify that the operating temperature range aligns with the system's environmental constraints before integration.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C654 series of low-voltage UARTs. It shares functional similarities with other members like the ST16C654DCQ64-F but differs in package type and manufacturing lot specifications. The series is characterized by CMOS technology and low power consumption relative to older TTL-compatible UARTs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

ST16C654DCQ64-F is a documented alternative offering identical electrical specifications in an LQFP-64 package. Designers must account for pinout differences between PLCC and LQFP footprints when substituting.
