• Fast FLASH non-volatile memory for instant-on operation
• 44-pin VQFP package with 34 user I/O pins
• 3.3V supply voltage with 5V tolerant inputs

Complex Programmable Logic Devices Applications

• Logic replacement for legacy TTL/CMOS circuits
• Address decoding and bus interfacing
• Simple state machine implementation
• Level shifting between different voltage domains

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' against the manufacturer's official datasheet to confirm lead-free compliance and RoHS status. Ensure the -7 speed grade matches the timing requirements of the target design. Confirm package integrity as the VQFP form factor requires appropriate soldering profiles during assembly.

Complex Programmable Logic Devices Selection Notes

Select this component when a small number of macrocells are sufficient for glue logic applications. The XC9536XL provides a cost-effective solution compared to larger CPLDs or FPGAs. Consider the 3.3V operating voltage and ensure compatibility with the system's I/O standards. The non-volatile nature eliminates the need for external configuration PROMs.

Complex Programmable Logic Devices Part Context

This part is part of the XC9500XL series, an evolution of the original XC9500 family. It retains pin-to-pin compatibility with many XC9500 devices but offers improved performance and lower power consumption due to advanced CMOS technology. The series is widely used in industrial and consumer electronics for simple programmable logic tasks.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other variants within the XC9500XL family, such as the XC9536-7VQG44C, provided speed grades are compatible. Cross-family migration to XC9572XL may require schematic changes due to increased I/O count.
