XC95108-7PC84C

Complex Programmable Logic Devices Overview

The XC95108-7PC84C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500 family, manufactured by AMD. It features 108 macrocells and 2400 usable gates organized into 6 Logic Array Blocks (LABs). The device utilizes non-volatile Flash memory for configuration storage, allowing for in-system programmability. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a PC-84 package. The component is rated for commercial temperature operation between 0°C and +70°C, with a maximum propagation delay of 7.5 ns and a maximum operating frequency of 125 MHz.

Complex Programmable Logic Devices Feature Summary

• 108 Macrocells and 2400 Gates across 6 LABs
• Non-volatile Flash memory technology for instant-on functionality
• 7.5 ns maximum propagation delay at 125 MHz
• 5 V single-supply operation (4.5 V to 5.5 V)

Complex Programmable Logic Devices Applications

• General-purpose logic replacement
• Address decoding and bus interfacing
• State machine implementation

Complex Programmable Logic Devices Procurement Notes

Verify current availability status as the XC9500 series may have limited production runs or end-of-life implications. Confirm package authenticity and check for moisture sensitivity level (MSL) handling requirements prior to assembly. Ensure compatibility with existing programming tools for Flash-based CPLDs.

Complex Programmable Logic Devices Selection Notes

Select this part when 108 macrocells are sufficient for the design logic. The 7 ns speed grade is suitable for moderate-frequency applications up to 125 MHz. The PC-84 package offers a compact footprint compared to larger PQFP options. Verify that the 5 V I/O levels match the system interface requirements.

Complex Programmable Logic Devices Part Context

This component belongs to the XC9500 high-performance CPLD family, which introduced Flash memory technology to replace earlier EPROM-based devices. The XC95108 variant provides a balance of density and speed, serving as a drop-in replacement for GALs and PALs in legacy designs while offering reprogrammability.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same speed grade include the XC95108-7PC84I (industrial temperature range -40°C to +85°C). Other XC9500 variants like the XC9572 or XC9536 offer lower densities but share the same architecture.
