XC18V512PCG20C

Overview

The XC18V512PCG20C is a 512K-bit (64K x 8) In-System Programmable PROM device manufactured by AMD. It utilizes a 20-pin PLCC package and operates at a supply voltage of 3.0V to 3.6V. The component supports serial programming via the JTAG interface, allowing for configuration updates without removal from the circuit board. It features high-speed access times and is designed for use in digital logic applications requiring non-volatile storage.

Feature Summary

• Supports In-System Programming for flexible configuration updates
• Utilizes JTAG interface for secure serial data loading
• Provides non-volatile memory retention without power

Applications

• Configuration storage for FPGA devices
• Digital logic implementation in embedded systems
• Boot code storage for microcontroller systems

Procurement Notes

Verify the specific suffix 'CG' indicates commercial temperature range and lead-free packaging compliance. Confirm the '20C' denotes the 20-pin PLCC package variant. Ensure compatibility with existing JTAG programming infrastructure before procurement. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a 64K x 8 bit capacity is required for non-volatile configuration. Consider the 20-pin PLCC package constraints for PCB layout. Evaluate the need for In-System Programmability versus one-time programmable alternatives based on update frequency requirements.

Part Context

This part belongs to the Xilinx CoolRunner-II or similar CPLD/FPGA configuration PROM family. It serves as a dedicated memory solution for storing configuration bitstreams. The device is engineered to interface directly with compatible programmable logic devices, providing reliable boot-up sequences.

Replacement Considerations

XC18V02PC44C offers higher density but different pinout. Verify electrical compatibility and physical footprint differences before substitution. Cross-reference datasheets for timing parameter alignment.
