XC95108-20TQG100C

Complex Programmable Logic Devices Overview

The XC95108-20TQG100C is a Complex Programmable Logic Device (CPLD) belonging to the AMD XC9500 family. It integrates 108 macrocells and supports up to 64 user I/O pins within a 100-pin TQFP package. The device features In-System Programmability (ISP) via JTAG, allowing for non-volatile configuration with over 10,000 erase/write cycles. Electrical specifications include a maximum propagation delay of 20 ns and an operating voltage range of 4.75V to 5.25V. The component is designed for surface-mount applications and operates within a commercial temperature range of 0°C to 70°C.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'TQG100C' against official AMD documentation to confirm the package type and temperature grade. Confirm RoHS compliance status as older XC9500 variants may not meet current environmental standards. Check for obsolescence notices or last-time buy notifications from authorized distributors before procurement planning.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require moderate logic density (approx. 10k equivalent gates) with guaranteed non-volatility. Ensure the system voltage aligns with the 5V requirement, as the XC9500 family does not support lower voltage levels natively. Verify that the TQFP100 footprint matches the PCB layout constraints and that JTAG programming infrastructure is available for field updates.

Complex Programmable Logic Devices Part Context

The XC9500 series represents AMD's (formerly Xilinx) high-performance Flash CPLDs, bridging the gap between complex FPGAs and simple PLDs. Unlike SRAM-based FPGAs, these devices provide immediate power-up functionality without external configuration memory. The XC95108 variant offers a balance of pin count and logic resources suitable for mid-complexity digital logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to the proprietary architecture. Consider Lattice Semiconductor's ispMACH 4000ZE or MachEX families for similar logic density and ISP capabilities. Verify electrical compatibility, particularly regarding VCC requirements and I/O drive strengths, when evaluating alternative vendors.
