XC9536-5VQG44C

Complex Programmable Logic Devices Overview

The XC9536-5VQG44C is a Complex Programmable Logic Device (CPLD) from the Xilinx XC9500XL family, manufactured by AMD. It features 36 macrocells and up to 800 usable gates within a single functional block. The device supports up to 34 user I/O pins and offers pin-to-pin logic delays of 5 ns, enabling clock frequencies up to 100 MHz. It operates on a 5 V supply voltage with in-system programmability (ISP) via JTAG. The component utilizes CMOS technology and is housed in a 44-pin Very Thin Quad Flat Package (VQFP).

Complex Programmable Logic Devices Feature Summary

• 36 Macrocells with 800 usable gates for flexible logic implementation.
• 5 ns maximum pin-to-pin delay supporting operation up to 100 MHz.
• In-System Programmability (ISP) allowing updates without removing the chip.
• 44-pin VQFP package with up to 34 user I/O pins.

Complex Programmable Logic Devices Applications

• General-purpose digital logic replacement.
• Address decoding and bus interfacing.
• State machine implementation in industrial control systems.
• Level shifting between different voltage domains.

Complex Programmable Logic Devices Procurement Notes

Verify the manufacturer origin, as the XC9500 series was originally developed by Xilinx before its acquisition by AMD. Confirm the specific suffix 'C' indicates commercial temperature range and lead-free composition if required by design specifications. Ensure the package type matches the 44-pin VQFP footprint. Check for end-of-life status or obsolescence notices from the manufacturer regarding this specific part number.

Complex Programmable Logic Devices Selection Notes

Select this component when a low gate count CPLD with fast propagation delays is required. The 5 ns speed grade is suitable for moderate-speed synchronous designs. Compare against the XC9536-10 variant if slower speeds are acceptable for lower power consumption. Ensure the design fits within the 36 macrocell limit and that the 34 available I/O pins meet the interface requirements.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500XL family, which succeeded the original XC9500 series. The XL series introduced Flash memory technology, eliminating the need for UV erasure and enabling true In-System Programmability. The XC9536 represents the entry-level density in this family, offering a balance of performance and cost for simple logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other variants in the XC9500XL family such as XC9536-5VQG44I for industrial temperature ranges. Cross-family migration may require redesigning the logic structure due to differences in macrocell architecture between CPLDs and FPGAs.
