XC18V512VQ44C

XC18V512VQ44C Description

The XC18V512VQ44C is a 512kb Serial Configuration PROM manufactured by AMD (formerly Xilinx), designed for storing configuration data for FPGAs. Housed in a 44-pin VQFP package, it operates within a 3V to 3.6V supply range and supports in-system programmability (ISP), enabling flexible field updates. This device is surface-mountable and features a 0°C to 70°C operating temperature range, making it suitable for industrial and commercial applications. Although marked as obsolete, it remains relevant in legacy systems requiring reliable, non-volatile configuration storage.

XC18V512VQ44C Features

• Memory Capacity: 512kb storage for FPGA bitstreams.
• In-System Programmable (ISP): Allows reprogramming without removal from the circuit.
• Wide Voltage Range: 3V–3.6V operation ensures compatibility with low-power systems.
• Surface-Mount Design: 44-VQFP package optimizes board space.
• Extended Temperature Support: 0°C to 70°C range for stable performance in varied environments.
• Moisture Sensitivity Level (MSL) 3: Requires baking if exposed beyond 168 hours before reflow.
• REACH Unaffected: Compliant with environmental regulations.

XC18V512VQ44C Applications

• FPGA Configuration: Primary use for Xilinx FPGAs, ensuring reliable boot-up configuration.
• Industrial Control Systems: Suitable for automation equipment requiring robust, reprogrammable memory.
• Legacy Electronics Maintenance: Ideal for servicing older systems where newer alternatives are incompatible.
• Embedded Systems: Used in designs needing compact, non-volatile storage for firmware or settings.

Conclusion of XC18V512VQ44C

The XC18V512VQ44C offers a balance of reliability, reprogrammability, and legacy compatibility, making it a pragmatic choice for FPGA-based systems despite its obsolete status. Its ISP capability and industrial-grade specs ensure longevity in applications where newer alternatives may not integrate seamlessly.
