XC9572-15PC44I

XC9572-15PC44I Description

The XC9572-15PC44I is a 72-macrocell CPLD (Complex Programmable Logic Device) from AMD's XC9500 series, designed for high-performance digital logic applications. Operating with an internal supply voltage of 4.5V to 5.5V, it features 34 I/O pins and delivers a maximum propagation delay (tpd) of 15 ns, making it suitable for timing-critical designs. Housed in a 44-pin PLCC (Plastic Leaded Chip Carrier) package, this device is surface-mountable and supports in-system programmability (ISP) with a minimum endurance of 10,000 program/erase cycles. Though marked as obsolete, it remains relevant for legacy systems requiring reliable, low-power reconfigurable logic.

XC9572-15PC44I Features

• High-Density Logic: Integrates 72 macrocells and 4 logic blocks, equivalent to 1,600 gates, enabling complex logic implementations.
• Fast Performance: 15 ns max delay ensures rapid signal processing for real-time applications.
• Flexible I/O: 34 I/O pins provide ample connectivity for interfacing with peripherals.
• In-System Programmability (ISP): Allows field updates without physical removal, reducing downtime.
• Robust Endurance: 10K program/erase cycles guarantee long-term reliability.
• Legacy Compatibility: Ideal for maintaining or upgrading older systems due to its 5V operation and PLCC packaging.

XC9572-15PC44I Applications

• Industrial Control Systems: Used for glue logic, state machines, and I/O expansion in automation equipment.
• Telecommunications: Interfaces and protocol bridging in legacy telecom hardware.
• Embedded Systems: Custom logic for microcontroller peripherals or bus arbitration.
• Automotive Electronics: Timing-critical functions in older vehicle control modules.
• Test & Measurement: Reconfigurable logic for instrumentation and data acquisition systems.

Conclusion of XC9572-15PC44I

The XC9572-15PC44I offers a balanced mix of speed, density, and reconfigurability, making it a pragmatic choice for legacy 5V designs. Its ISP capability and high macrocell count distinguish it from simpler PLDs, while the 15 ns performance ensures responsiveness in time-sensitive applications. Though obsolete, its REACH compliance and industrial-grade reliability sustain its utility in maintenance-focused sectors. Engineers seeking a proven, reprogrammable logic solution for 5V systems will find this CPLD a dependable option.
