XC95108-10PC84C

XC95108-10PC84C Description

The XC95108-10PC84C 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 a gate count of 2400. Operating within a 5V supply range (4.75V–5.25V), it features a maximum propagation delay of 10 ns, ensuring rapid signal processing. The device supports in-system programmability (ISP) with a minimum endurance of 10,000 program/erase cycles, making it suitable for iterative development and field upgrades. Although classified as obsolete, it remains relevant for legacy systems due to its reliability and performance.

XC95108-10PC84C Features

• High-Density Logic Integration: Combines 108 macrocells and 69 I/O pins in a compact 84-pin package.
• Fast Performance: 10 ns maximum delay enables high-speed logic operations.
• In-System Programmability (ISP): Allows reconfiguration without removing the device from the circuit.
• Wide Operating Temperature: Functions reliably in 0°C to 70°C environments.
• Surface-Mount Design: Facilitates integration into modern PCB assemblies.
• Legacy Compatibility: Ideal for maintaining or upgrading older systems using 5V logic.
