XC18V04PC44C

Overview

The XC18V04PC44C is a 4 Mbit EEPROM-based FPGA configuration memory device manufactured by AMD. It operates at a maximum frequency of 33 MHz with a supply voltage range of 3.0 V to 3.6 V. The component is designed for surface mount installation in a PLCC-44 package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Non-volatile storage architecture utilizing EEPROM technology for persistent data retention
• Integrated serial interface supporting high-speed programming cycles up to 33 MHz
• Industrial-grade thermal stability ensuring reliable operation across wide temperature extremes

Applications

• Configuration storage for Xilinx Field Programmable Gate Arrays
• Embedded system boot code persistence
• Industrial control hardware initialization memory

Procurement Notes

Verify the specific suffix 'C' against official AMD documentation to confirm commercial grade temperature ratings versus industrial variants. Ensure compatibility with the target FPGA's configuration mode requirements before procurement. Cross-reference the PLCC-44 footprint with PCB design constraints to guarantee physical fitment.

Selection Notes

Select this component when non-volatile configuration storage is required for Xilinx devices. The 4 Mbit capacity suits medium-complexity designs. Verify that the 3.3 V operating voltage aligns with the system power rails. Confirm the PLCC-44 package availability matches assembly capabilities.

Part Context

This part belongs to the XC18V00 series of configuration PROMs. These devices are specifically engineered to store bitstream data for Xilinx FPGAs. They provide a cost-effective solution for single-chip configuration without requiring external volatile memory controllers.

Replacement Considerations

Consult AMD datasheets for direct pin-compatible substitutes within the XC18V series. Verify electrical specifications match exactly. Generic EEPROMs are not suitable due to specific protocol requirements.
