UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IJ28-F' against official MaxLinear documentation to confirm the exact temperature grade and packaging variant. Ensure compatibility with the target system's voltage levels and bus timing requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with moderate FIFO depth is required for Intel-bus compatible systems. Consider the -40°C to +85°C industrial temperature rating for harsh environments. Evaluate the 1.5 Mbit/s maximum data rate against application bandwidth needs. Compare pinout compatibility if replacing legacy Exar or similar UART devices in existing designs.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C155x family of UART controllers, which are widely used in embedded applications. The series is known for its compatibility with Intel 8250/16450/16550 standards while offering enhanced FIFO capabilities. MaxLinear acquired the Exar UART product line, continuing support for these established interface solutions.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct replacements may include the ST16C1550CJ28 or ST16C1550IQ48 depending on package constraints. Verify electrical specifications and pin assignments carefully when substituting across different package types such as PLCC versus TQFP.
