XC9572-15TQ100C

XC9572-15TQ100C Description

The XC9572-15TQ100C is a high-performance Complex Programmable Logic Device (CPLD) from AMD's XC9500 series, designed for flexible digital logic implementation. This 72-macrocell device features 4 logic blocks, offering 1,600 gates with a 15 ns maximum propagation delay, making it suitable for medium-speed applications. Operating within a 5V supply range (4.75V–5.25V) and a 0°C to 70°C temperature range, it is ideal for industrial and commercial environments. The 100-pin TQFP package ensures compact surface-mount integration, while its In-System Programmable (ISP) capability allows for 10,000 program/erase cycles, enabling field updates without removal from the circuit.

XC9572-15TQ100C Features

• 72 I/O Pins: High pin count for versatile interfacing.
• In-System Programmability: Supports min 10K cycles for reconfigurable designs.
• 15 ns Propagation Delay: Balanced speed for timing-critical applications.
• 4 Logic Blocks: Efficient resource allocation for complex logic.
• 5V Operation: Compatible with legacy TTL/CMOS systems.
• Surface-Mount TQFP Package: Space-saving 100-pin design.
• Obsolete Status: Still valuable for legacy system maintenance or replacements.

XC9572-15TQ100C Applications

• Industrial Control Systems: Logic glue, state machines, and I/O expansion.
• Telecommunications: Protocol bridging and signal conditioning.
• Legacy Equipment Upgrades: Cost-effective replacement for older PLDs.
• Embedded Systems: Customizable interfacing for microcontrollers.
• Automotive Electronics: Non-critical control logic (within temp limits).

Conclusion of XC9572-15TQ100C

The XC9572-15TQ100C excels in medium-complexity logic designs requiring reprogrammability and 5V compatibility. While obsolete, its high macrocell count, ISP flexibility, and 15 ns performance make it a pragmatic choice for legacy upgrades or systems avoiding migration to newer low-voltage CPLDs. Engineers value its balance of speed, density, and reliability in cost-sensitive or maintenance-focused projects.
