XC18V04VQ44C

Overview

The XC18V04VQ44C 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 supports surface-mount installation in a 44-pin VQFN package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides non-volatile storage for FPGA configuration data using EEPROM technology
• Supports high-speed serial programming interface for rapid data transfer
• Designed for reliable operation across extended industrial temperature ranges

Applications

• Configuration of Xilinx Field Programmable Gate Arrays
• Industrial control systems requiring persistent logic settings
• Embedded communication equipment needing reliable boot-up states

Procurement Notes

Verify the specific suffix 'VQ44C' against official AMD documentation to confirm the exact package type, temperature grade, and lead-free status. Ensure compatibility with the target FPGA's configuration mode requirements before procurement.

Selection Notes

Select this component when a 4 Mbit capacity is required for FPGA initialization. Consider the VQFN package constraints and 3.3 V operating voltage. Verify that the 33 MHz clock speed meets the system's configuration timing requirements.

Part Context

This part belongs to the XC18V00 series of configuration PROMs. These devices are specifically engineered to store bitstream data for Xilinx FPGAs, ensuring deterministic startup behavior without external microcontrollers.

Replacement Considerations

Check for direct cross-references such as XC18V04VQ44I if industrial temperature variants are needed. Confirm pinout and electrical specifications match exactly before substituting.
