XC18V01VQG44C0100

Overview

The XC18V01VQG44C0100 is a 3.3V in-system programmable configuration PROM from the XC18V00 series, manufactured by AMD/Xilinx. It provides 1 Megabit (1,048,576 bits) of storage for FPGA bitstreams and is housed in a 44-pin VQFP package. The device supports both serial and parallel configuration modes, featuring low-power advanced CMOS FLASH technology. It operates within an industrial temperature range of -40°C to +85°C and includes JTAG support for programming and boundary-scan testing.

Feature Summary

• Supports in-system programming via standard IEEE 1149.1 JTAG protocol
• Offers dual configuration modes: serial and parallel
• Features 5V-tolerant I/O pins compatible with various signal levels
• Includes design security options to inhibit unauthorized reading

Applications

• Configuration of Xilinx Virtex-II and Virtex-E FPGAs
• Configuration of Xilinx Spartan-IIE and Spartan-IIF FPGAs
• Configuration of Xilinx Spartan-3 FPGAs

Procurement Notes

Verify that the component is sourced as obsolete or under obsolescence status. Confirm the specific suffix '0100' matches the required lead-free packaging variant. Ensure compatibility with the target FPGA's configuration requirements before procurement.

Selection Notes

Select this part when a 1 Megabit capacity is sufficient for the target FPGA design. Choose the VQFP package for surface-mount applications requiring 44 pins. Verify that the system supports 3.3V logic levels and requires in-system reprogrammability capabilities.

Part Context

This component belongs to the XC18V00 series of configuration PROMs. It serves as a non-volatile memory solution for storing configuration data for Xilinx FPGAs. The series includes variants with different capacities such as 512Kbit, 2Mbit, and 4Mbit.

FAQ

How is the CF pin function handled in 20-pin packages?

In 20-pin packages, the CF pin function can be routed to pin 7 using the CF → D4 setting, provided parallel output mode is not used.

What is the purpose of the CEO output?

The CEO output drives the CE input of the next PROM in a daisy chain, allowing multiple devices to be cascaded for larger configuration memories.
