XC9536XL-10VQ44I

Complex Programmable Logic Devices Overview

The XC9536XL-10VQ44I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, housed in a 44-pin VQFP surface-mount package. It features 36 macrocells and supports up to 34 I/O pins within a design utilizing 800 system gates organized into two Logic Array Blocks (LABs). The device operates on a single 3.3V supply voltage with a maximum operating frequency of 178 MHz. Key electrical specifications include a maximum propagation delay of 10 ns and a typical operating current of 10 mA. It utilizes non-volatile Flash memory for configuration retention.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash memory architecture eliminates the need for external configuration PROMs.
• High-speed performance with a maximum propagation delay of 10 ns and operating frequency up to 178 MHz.
• In-system programmability allows for field updates without removing the component from the circuit board.
• Supports 3.3V operation with high noise immunity and compatibility with standard logic families.

Complex Programmable Logic Devices Applications

• Address decoding and chip select generation in embedded systems.
• Translation between different voltage domains or logic standards.
• State machine implementation for industrial control sequences.
• Bus buffering and protocol conversion in communication interfaces.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature range (typically -40°C to +85°C) compared to the commercial 'C' variant. Confirm the '10' speed grade matches the required timing constraints for the target application. Ensure the VQFP-44 package footprint aligns with the PCB layout, as pin counts differ from other packages in the XC9500XL series.

Complex Programmable Logic Devices Selection Notes

Select this model when non-volatile storage is required to retain the design after power loss, avoiding the cost and board space of external configuration devices. The 36-macrocell capacity is suitable for moderate complexity logic functions. Verify that the 10 ns delay meets the system clock requirements; faster variants like the '-5' are available if tighter timing margins are necessary.

Complex Programmable Logic Devices Part Context

This component belongs to the XC9500XL series, an evolution of the original XC9500 line featuring lower power consumption and higher density. It serves as a drop-in replacement for legacy CPLDs in designs requiring reliable, reprogrammable logic. The part integrates directly with AMD/Xilinx development tools such as Vivado or older ISE platforms for design entry and programming.

Complex Programmable Logic Devices Replacement Considerations

Direct functional equivalents within the same package and logic density include the XC9536XL-5VQ44I for faster switching speeds or XC9536XL-10VQ44C for commercial temperature ranges. Cross-series upgrades may require schematic modifications due to differences in I/O drive strength or pinout configurations.
