XC9536-6VQ44C

Complex Programmable Logic Devices Overview

The XC9536-6VQ44C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, housed in a 44-pin VQFP package. It features 36 macrocells and 800 usable gates organized into two Logic Array Blocks (LABs). The device supports up to 34 user I/O pins and operates at a maximum frequency of 178 MHz with a typical propagation delay of 6 ns. Designed for surface-mount installation, it functions within a commercial temperature range of 0°C to +70°C and requires a 3.3V supply voltage.

Complex Programmable Logic Devices Feature Summary

• Flash-based non-volatile architecture enabling In-System Programming (ISP) without externalEPROM
• High-speed performance with 6 ns pin-to-pin logic delays and 178 MHz operating frequency
• Flexible 36V18 Function Block providing 90 product terms to drive any or all of 18 macrocells
• Enhanced pin-locking architecture allowing flexible placement of I/O pins on the package

Complex Programmable Logic Devices Applications

• High-density glue logic replacement in digital systems
• Address decoding and bus interfacing for microprocessors
• State machine implementation in industrial control applications
• Level translation between different voltage domains

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '6' indicates the 6 ns speed grade variant within the XC9536XL series. Confirm the manufacturer source, as production rights transitioned from Xilinx to AMD. Ensure the component meets RoHS compliance standards required for modern assembly processes. Check for obsolescence status as older CPLD families may have limited long-term availability.

Complex Programmable Logic Devices Selection Notes

Select this part when a moderate density solution with fast propagation delays is required for 3.3V systems. Compare against the XC9536-7VQ44C if a slower, potentially lower-cost option suffices for the timing constraints. Consider the XC9572XV if higher gate counts are needed, noting the voltage difference between XL and XV series families.

Complex Programmable Logic Devices Part Context

This component belongs to the XC9500XL family, which succeeded the original XC9500 series by offering lower power consumption and improved performance while maintaining compatibility. The XC9536 designation refers to the 36 macrocell capacity, distinguishing it from smaller variants like the XC9514 or larger ones like the XC9572.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements include other XC9536XL variants with compatible packages, such as the XC9536XL-6VQ44C. Cross-family substitution with the XC9536V series is possible but requires verification of voltage level differences (3.3V vs 5V) and timing parameters.
