XC9536XL-7VQG44I

Overview

The XC9536XL-7VQG44I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family. It features 36 macrocells, 800 usable gates, and 34 I/O pins housed in a 44-pin VQFP package. Operating at 3.3V with a supply range of 3.0V to 3.6V, it delivers a maximum propagation delay of 7ns and a max frequency of 125MHz. The device utilizes non-volatile Flash memory for configuration, supports industrial temperature ranges (-40°C to +85°C), and draws approximately 10mA operating current.

Feature Summary

• Non-volatile Flash technology enables instant-on functionality without external configuration memory.
• High-speed performance with 7ns maximum propagation delay and 125MHz system clock capability.
• Low power consumption with 10mA typical operating current and support for 3.3V logic levels.
• Industrial temperature rating (-40°C to +85°C) ensures reliability in demanding environments.

Applications

• High-density logic replacement in industrial control systems.
• Address decoding and bus bridging in embedded computing architectures.
• State machine implementation for automated test equipment.
• Interface translation between legacy 5V and modern 3.3V digital components.

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the 'VQG44' designation matches the 44-lead Very Thin Quad Flat Package requirements. Ensure design compatibility with 3.3V I/O standards as this device does not support 5V tolerant inputs on all pins without verification. Check current availability status as older CPLD series may have limited production runs.

Selection Notes

Select this model when non-volatile storage is required to eliminate external configuration chips. Compare against the XC9536XL-5 variant if higher speed (5ns delay) is needed but industrial temperature range is not critical. Ensure the 34 I/O count meets interface requirements; otherwise, consider the XC9572XL for increased capacity. Verify voltage level compatibility with connected peripherals, as the device operates strictly at 3.3V.

Part Context

This component belongs to the XC9500XL series, an enhanced version of the original XC9500 line featuring lower power consumption and Flash-based non-volatility. It serves as a drop-in replacement for many EPROM-based CPLDs while reducing system complexity by removing external configuration devices. The series is widely used for general-purpose programmable logic in cost-sensitive applications.

Replacement Considerations

Direct pin-compatible alternatives within the same package include the XC9536XL-5VQG44I (faster speed, commercial temp) or XC9536-7VQG44 (older EPROM-based technology). Cross-family replacements like the XC9572XL offer more macrocells but require schematic review for I/O mapping changes.
