XC9536XL-7VQ64C

Overview

The XC9536XL-7VQ64C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, housed in a 64-pin VQFP package. It features 36 macrocells and supports system frequencies up to 100 MHz with a maximum pin-to-pin delay of 7 ns. The device operates at a supply voltage of 3.3V, providing high performance while maintaining low power consumption characteristics typical of CMOS technology.

Feature Summary

• 36 Macrocells with 800 usable logic gates
• Maximum operating frequency of 100 MHz
• Pin-to-pin propagation delay of 7 ns
• 3.3V single-supply operation

Applications

• General-purpose digital logic implementation
• Address decoding and bus interfacing
• State machine control in embedded systems
• Replacement for legacy TTL/CMOS logic gates

Procurement Notes

Verify the suffix 'VQ64C' confirms the 64-pin Very Thin Quad Flat Package (VQFP) and Commercial temperature range (-40°C to +85°C). Ensure the source document explicitly lists this part number to confirm availability and authenticity, as XC9500XL devices are mature products with potential obsolescence considerations.

Selection Notes

Select this component when 36 macrocells are sufficient for the design logic. Compare against XC9536 variants with different speed grades (e.g., -10) if lower latency is required, or larger devices like XC9572XL if more logic resources are needed. Confirm the VQFP package fits the PCB footprint constraints.

Part Context

This part belongs to the XC9500XL series, an enhanced version of the original XC9500 CPLD family. It offers improved performance and lower power consumption compared to its predecessor while maintaining pin compatibility with many XC9500 devices. The series is known for non-volatile Flash memory configuration.

Replacement Considerations

Direct pin-compatible replacements within the same family include XC9536XL-10VQ64C (slower speed grade) or XC9536-7VQ64C (original generation, verify voltage compatibility). Cross-family replacements require schematic redesign.
