XC95108-15PC84C

XC95108-15PC84C Description

The XC95108-15PC84C is a Complex Programmable Logic Device (CPLD) from AMD's XC9500 series, offering 108 macrocells and 69 I/O pins in a 84-pin PLCC (Plastic Leaded Chip Carrier) package. Designed for high-performance logic integration, it operates at a 5V internal supply voltage (4.75V–5.25V) with a maximum propagation delay of 15 ns, making it suitable for timing-critical applications. This surface-mount device supports in-system programmability (ISP) with a minimum of 10,000 program/erase cycles, enabling flexible field updates. Although marked as obsolete, it remains relevant for legacy systems due to its robust architecture and 2,400-gate equivalent logic capacity.

XC95108-15PC84C Features

• High-Density Logic: Integrates 6 logic blocks with 108 macrocells for complex designs.
• Fast Performance: 15 ns pin-to-pin delay ensures rapid signal processing.
• In-System Programmability (ISP): Allows reconfiguration without physical removal, reducing downtime.
• Wide Operating Temperature: 0°C to 70°C for industrial and commercial environments.
• 5V Operation: Compatible with legacy TTL/CMOS systems.
• Surface-Mount Packaging: 84-PLCC for compact PCB integration.
• High Reliability: REACH unaffected and MSL 3 (168 hours) moisture sensitivity.

XC95108-15PC84C Applications

• Legacy System Upgrades: Ideal for retrofitting older 5V-based control systems.
• Communication Interfaces: Used in UART, SPI, or I2C protocol bridging.
• Industrial Control: Suitable for PLCs, motor control, and sensor interfacing.
• Embedded Systems: Acts as a glue logic for FPGA or microprocessor peripherals.
• Test Equipment: Provides reconfigurable logic for prototyping and validation.

Conclusion of XC95108-15PC84C

The XC95108-15PC84C is a high-performance CPLD offering a balance of logic density, speed, and reprogrammability, tailored for 5V systems. While obsolete, its ISP capability and 15 ns timing make it a pragmatic choice for legacy upgrades or cost-sensitive designs requiring reliable programmable logic. Engineers valuing backward compatibility and low-risk integration will find this CPLD a practical solution.
