XC18V02PC44I

Overview

The XC18V02PC44I is a 2-megabit in-system programmable configuration PROM designed for Xilinx FPGAs. It operates on a 3.3V supply with a voltage range of 3.0V to 3.6V and supports industrial temperatures from -40°C to +85°C. The device utilizes a PLCC-44 package and features low-power CMOS FLASH technology. It supports serial configuration clocks up to 33 MHz and parallel data rates up to 264 Mb/s at the same frequency. The component offers 20,000 program/erase cycles and includes JTAG boundary-scan support.

Feature Summary

• In-system programmable via standard 4-pin JTAG protocol
• Supports Master Serial, Slave Serial, and Parallel configuration modes
• Cascadable architecture using CEO output for expanded memory
• 5V tolerant I/O pins accepting 5V, 3.3V, and 2.5V signals

Applications

• Configuration of Virtex-II FPGA devices
• Configuration of Spartan-II and Spartan-IIE FPGA devices
• Configuration of Virtex-E and Virtex FPGA devices

Procurement Notes

Verify the specific suffix 'PC44' confirms the 44-pin PLCC package and 'I' indicates the industrial temperature grade. Confirm the manufacturer source as AMD/Xilinx or authorized distributors. Ensure the datasheet version matches the required specifications for your design implementation.

Selection Notes

Select this component when a 2-megabit capacity is required for FPGA configuration. Choose the PC44 package if surface-mount PLCC form factor is preferred over VQFP. Ensure the system supports 3.3V logic levels and requires in-system reprogrammability for design iterations.

Part Context

This part belongs to the XC18V00 series of in-system programmable configuration PROMs. The series includes variants with 512-kilobit, 1-megabit, and 4-megabit capacities. These devices provide a cost-effective method for storing and reprogramming FPGA bitstreams with high endurance and security features.

Replacement Considerations

Direct substitutes include other members of the XC18V00 series such as XC18V04PC44I for higher capacity or XC18V01PC44I for lower capacity, provided pin compatibility and memory size requirements are met.
