The XC18V256SC is a Configuration PROM (programmable read-only memory) from Xilinx, designed to store the configuration data for Xilinx Field-Programmable Gate Arrays (FPGAs). This PROM provides a simple and efficient method for loading the FPGA's configuration at startup. It has a memory capacity of 256 Kilobits. The 'SC' likely refers to the package type and temperature range.

Applications

• Configuration storage for Xilinx FPGAs.
• FPGA bootloading in embedded systems.
• Storing configuration bitstreams for programmable logic devices.
• Use in prototyping and low-volume production runs.
• Systems requiring a simple and reliable FPGA configuration solution.

Features

• 256 Kilobit (32K x 8) memory capacity.
• In-System Programmable (ISP) via JTAG.
• Low power consumption.
• Fast configuration time.
• Serial configuration interface.
• Non-volatile storage.

Benefits

• Reliable FPGA initialization: Ensures proper FPGA configuration upon power-up.
• Cost-effective solution: Provides a low-cost method for storing configuration data.
• Simplified programming: In-system programming via JTAG streamlines the development process.
• Compact design: Allows for smaller and more efficient board layouts.
• Non-volatile storage: Retains configuration data even when power is removed.

Additional Details

The XC18V256SC is programmed using the standard JTAG (IEEE 1149.1) interface, which allows for in-system programming. This simplifies the development and debugging process. The device operates at a low voltage, making it suitable for low-power applications. It is a non-volatile memory, which means that the configuration data is retained even when the power is turned off. The data is transferred to the FPGA serially.
