FIFOs Memory Procurement Notes

Verify the specific suffix 'JR' against the manufacturer's official datasheet to confirm package type and temperature rating. Ensure the source document explicitly identifies Quality Semiconductor as the original manufacturer or authorized licensee. Cross-reference the part number with current Microchip documentation if applicable, as Quality Semiconductor assets may have been acquired. Confirm availability through authorized distributors only.

FIFOs Memory Selection Notes

Select this component when a 1K x 9 asynchronous FIFO is required with an 80 ns access speed. It is suitable for applications needing parallel data buffering with 3-state output capability. Consider the PQCC32 package constraints for PCB layout. Verify that the 4.5 V to 5.5 V operating voltage range matches the system power supply specifications before implementation.

FIFOs Memory Part Context

The QS7202 series comprises asynchronous FIFO memories designed for high-performance data handling. This specific model offers 1K words of 9-bit width. The series is known for CMOS construction and standard logic interfaces. It serves as a reliable solution for temporary data storage in complex digital systems requiring precise timing control.

FIFOs Memory Replacement Considerations

Check for direct substitutes such as QS7202-12JR or QS7202-15JR if slower speeds are acceptable. Verify pinout compatibility with alternative manufacturers like IDT or Cypress before substitution.
