XC95108-15PQ100I

XC95108-15PQ100I Description

The XC95108-15PQ100I is a Complex Programmable Logic Device (CPLD) from AMD's XC9500 series, designed for high-performance digital logic applications. This 100-pin QFP (Quad Flat Package) device integrates 108 macrocells and 6 logic blocks, delivering 2,400 equivalent gates with a maximum propagation delay (tpd) of 15 ns. Operating within a 4.5V to 5.5V supply range, it supports In-System Programmability (ISP) with a minimum endurance of 10,000 program/erase cycles, making it ideal for field-upgradable designs.

XC95108-15PQ100I Features

• High Logic Density: 108 macrocells and 6 logic blocks provide flexible implementation of complex logic functions.
• Fast Performance: 15 ns maximum delay ensures rapid signal processing for time-critical applications.
• In-System Programmability (ISP): Allows reconfiguration without removing the device from the circuit, reducing downtime.
• 81 I/O Pins: Offers extensive interfacing capabilities for peripheral integration.
• 5V Operation: Compatible with legacy TTL systems, simplifying migration from older designs.
• Surface-Mount Package: 100-QFP form factor optimizes board space in compact designs.
• Obsolete Status: While no longer in production, it remains a reliable choice for legacy system maintenance.

XC95108-15PQ100I Applications

This CPLD excels in applications requiring glue logic consolidation, state machine control, and bus interfacing, such as:

• Industrial Control Systems: Real-time logic for automation and process control.
• Telecommunications: Protocol bridging and signal routing in legacy equipment.
• Embedded Systems: Customizable I/O expansion and timing management.
• Automotive Electronics: Interface logic for diagnostics and sensor networks.
• Legacy Upgrades: Cost-effective replacement for obsolete PALs/PLDs in existing hardware.

Conclusion of XC95108-15PQ100I

The XC95108-15PQ100I balances logic density, speed, and reconfigurability, making it a versatile solution for 5V-based digital systems. Its ISP capability and high I/O count distinguish it from simpler PLDs, while its 15 ns performance ensures responsiveness in timing-sensitive designs. Though marked as obsolete, it remains a pragmatic choice for sustaining legacy infrastructure or prototyping before transitioning to modern alternatives.
