XC95108-7PC84C

XC95108-7PC84C Description

The XC95108-7PC84C is a Complex Programmable Logic Device (CPLD) from AMD's XC9500 series, designed for high-performance digital logic applications. This 84-pin PLCC (Plastic Leaded Chip Carrier) device integrates 108 macrocells and 6 logic blocks, delivering 2,400 gate equivalents with a maximum propagation delay of 7.5 ns. Operating within a 5V supply range (4.75V–5.25V) and a temperature range of 0°C to 70°C, it is optimized for real-time control and logic integration in embedded systems.

XC95108-7PC84C Features

• In-System Programmability (ISP): Supports 10,000 program/erase cycles, enabling field upgrades without desoldering.
• High I/O Density: 69 I/O pins provide flexible interfacing for peripheral integration.
• Fast Performance: 7.5 ns propagation delay ensures rapid signal processing for timing-critical applications.
• Surface-Mount Packaging: 84-PLCC form factor suits space-constrained PCB designs.
• Reliable Logic Blocks: 6 logic blocks with 108 macrocells offer scalable logic implementation.
• Obsolete Status: While no longer in production, it remains a robust choice for legacy system maintenance.

XC95108-7PC84C Applications
