XC9572-15TQG100I

Complex Programmable Logic Devices Overview

The XC9572-15TQG100I is a Complex Programmable Logic Device (CPLD) belonging to the Xilinx XC9500XL family. It features 7,680 system gates and supports up to 84 user I/O pins within a 100-pin TQFP package. The device utilizes non-volatile Flash memory technology for configuration retention without external battery support. Key electrical specifications include a maximum propagation delay of 15 ns and operation across a supply voltage range of 2.7V to 3.6V. It supports in-system programming via JTAG interface.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash memory architecture eliminates the need for external configuration memories or batteries.
• Supports high-density logic implementation with 7,680 usable system gates.
• Capable of operating at clock frequencies up to 66 MHz under optimal conditions.
• Includes comprehensive JTAG boundary scan and in-system programming capabilities.

Complex Programmable Logic Devices Applications

• Logic level translation between different voltage domains.
• Address decoding and chip select generation in embedded systems.
• State machine implementation for industrial control applications.
• Replacement for legacy GALs and PALs in existing designs.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range compliance (-40°C to +85°C). Confirm package integrity for the 100-pin Thin Quad Flat Package (TQFP). Ensure sourcing channels provide genuine Xilinx components to avoid counterfeit risks associated with older CPLD families. Check for RoHS compliance status if required by current manufacturing standards.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile configuration is required without external PROMs. Compare gate density against XC9536XL or XC95144XL variants based on pin count and logic requirements. Consider the 15ns speed grade for timing-critical paths. Evaluate power consumption differences between 5V and 3.3V versions if system voltage constraints exist.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500XL series, an evolution of the original XC9500 family featuring Flash memory instead of EEPROM. It serves as a drop-in replacement for many standard logic functions previously handled by discrete gates or complex PLDs. The TQFP100 package offers a balance of pin count and board space efficiency for medium-complexity designs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements may include other XC9500XL variants with higher gate counts such as XC95144 or XC95288, provided pin assignments are remapped. Legacy XC9500 devices require external configuration memory and are not direct substitutes. Verify that alternative packages maintain the same thermal and mechanical specifications.
