XC18V02PCG44C0100

Overview

The XC18V02PCG44C0100 is an obsolete in-system programmable configuration PROM from the AMD/Xilinx XC18V00 series. It provides 2 Megabit storage capacity for Xilinx FPGA bitstreams. The device operates on a 3.3V supply with 5V-tolerant I/O pins. It supports serial and parallel configuration modes, featuring JTAG interface compliance for programming and boundary-scan testing. The component is housed in a 44-pin PLCC package.

Feature Summary

• In-System Programmable (ISP) capability via standard JTAG protocol
• Dual configuration modes supporting Master/Slave Serial and Parallel operations
• 5V-tolerant I/O pins compatible with 5V, 3.3V, and 2.5V signals
• Supports cascading multiple devices for extended memory requirements

Applications

• Configuration of Xilinx Virtex-II and Virtex-II Pro FPGAs
• Configuration of Xilinx Spartan-IIE and Spartan-3 FPGAs
• In-system reprogramming of FPGA design bitstreams
• Storage of configuration data for industrial temperature range applications

Procurement Notes

This part number is officially marked as Obsolete and no longer manufactured by AMD/Xilinx. Verification of availability should be restricted to authorized distributors offering surplus or new old stock inventory. Ensure that any sourced units are verified for authenticity and physical integrity prior to integration into designs.

Selection Notes

Select this component only for legacy systems requiring specific compatibility with older Xilinx FPGA families such as Virtex-II or Spartan-IIE. Consider the obsolescence status when planning long-term production lifecycles. Evaluate alternative modern configuration solutions if redesigning current hardware architectures.

Part Context

The XC18V00 series represents Xilinx's dedicated in-system programmable PROM family designed specifically for storing FPGA configuration data. These devices simplify the configuration process by providing non-volatile storage that can be updated without removing the chip from the board. The series includes various capacities to match different FPGA size requirements.

Replacement Considerations

Direct substitutes include the AT17LV002-10TQI from Microchip Technology. Verify pinout compatibility and voltage levels before substitution. Consult official datasheets for both components to ensure functional equivalence in the target application.
