UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the obsolete status and current availability through authorized distributors or surplus suppliers like Rochester Electronics. Confirm RoHS3 compliance and EAR99 classification before procurement. Ensure the 44-PLCC package matches the target PCB footprint. Check for alternative lead finishes if required by specific assembly processes.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a UART with 16-byte FIFO and IrDA support is required in a 44-PLCC package. Compare against SC16C550 variants from NXP for pin compatibility and feature parity. Verify that the 7V supply voltage and 1.5Mbps speed meet system requirements. Consider the obsolete status when planning long-term production cycles.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C550 family of UART ICs. It is functionally similar to the SC16C550 series produced by Philips/NXP. The 'I' suffix typically indicates industrial temperature range, while 'J44' denotes the 44-pin PLCC package. It serves as a legacy solution for serial communication in embedded systems.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C550IA44 from NXP is a documented equivalent offering identical UART functionality with 16-byte FIFO and IrDA support in a 44-PLCC package. Verify pinout compatibility and electrical specifications before substitution.
