- **Serial configuration interface** for Xilinx FPGAs.  
- **Low-power standby mode** for reduced power consumption.  
- **Automated programming** using Xilinx programming tools.  
- **Security bit** to prevent unauthorized readback.  
- **Industrial-standard pinout** for compatibility.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

In-system programmable configuration PROM.

Alternative Part Number

  • AT17LV256-10SU --: 256 Kbit FPGA configuration EEPROM in a 20-pin SOIC package, functionally equivalent to the XC18V256 and widely used as a drop-in configuration memory replacement.
  • EPC2LC20 --: Configuration device for SRAM-based FPGAs in a 20-pin PLCC package, offering comparable density and a similar role in the configuration chain.
  • M25P16-VMN6TP --: 16 Mbit serial configuration flash that can store FPGA bitstreams and serve as an alternative non-volatile configuration memory in many designs.
