XC95108-7TQ100C

Complex Programmable Logic Devices Overview

The XC95108-7TQ100C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, housed in a TQFP-100 surface-mount package. It features 108 macrocells and 2400 usable gates organized into six logic array blocks (LABs). The device operates at a maximum frequency of 125 MHz with a typical propagation delay of 7.5 ns. It utilizes non-volatile Flash memory for configuration, allowing for in-system programmability without external support components. Operating voltage ranges from 4.5 V to 5.5 V, with an operating temperature range of 0°C to 70°C.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash technology enables instant-on operation and supports multiple in-system programming modes.
• High-density architecture provides 108 macrocells and 6 LABs within a compact TQFP-100 package.
• Fast switching speed with a maximum frequency of 125 MHz and 7.5 ns propagation delay.
• Supports standard JTAG boundary scan testing for design verification.

Complex Programmable Logic Devices Applications

• Address decoding and bus bridging in embedded systems.
• Translation between different voltage domains or logic families.
• State machine implementation for control logic.
• Replacement of legacy GALs or PALs in existing designs.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature grade (0°C to 70°C) versus industrial variants. Confirm package integrity for TQFP-100 pins. Check current availability status as older CPLD series may have limited stock or end-of-life implications. Ensure ESD handling protocols are followed during procurement and storage.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile configuration is required to eliminate external EEPROMs. Compare gate count against XC9536 or XC9572 if more logic resources are needed. Verify that the 5V supply rail matches the system requirements, as lower voltage variants exist. Consider the TQFP-100 footprint constraints against PQFP or PLCC packages for PCB layout compatibility.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500XL series, an enhanced version of the original XC9500 line offering higher density and improved performance. It serves as a drop-in replacement for many complex PALs and GALs. The XC9500XL family bridges the gap between simple discrete logic and larger FPGAs, providing cost-effective solutions for moderate complexity logic functions.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other XC9500XL variants such as XC95108-7TQ100I for industrial temperature ranges. Cross-reference with Xilinx documentation for equivalent functionality in newer families like XC9500XV, noting potential differences in I/O standards and power consumption.
