The XC18V512SI is a Configuration PROM from Xilinx, used to store the configuration data for Xilinx Field-Programmable Gate Arrays (FPGAs). It provides a non-volatile memory solution to load the FPGA's configuration upon power-up. The XC18V512 has a memory capacity of 512 Kilobits. The 'SI' likely specifies the package type and temperature range.

Applications

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

Features

• 512 Kilobit (64K x 8) memory capacity.
• In-System Programmable (ISP) via JTAG.
• Low power consumption.
• Fast configuration download.
• Serial configuration interface.
• Non-volatile storage.

Benefits

• Reliable FPGA initialization: Ensures correct FPGA configuration at power-up.
• Cost-effective solution: Provides a low-cost way to store FPGA configuration data.
• Simplified programming: In-system programming simplifies the development process.
• Non-volatile storage: Retains configuration data without power.

Additional Details

The XC18V512SI is programmed through the industry-standard JTAG (IEEE 1149.1) interface, enabling in-system programming without removing the device. This simplifies design and debugging. The device is designed for low power operation and provides non-volatile storage, retaining configuration data even when power is off. Data is transferred serially during configuration. The 'SI' package and temperature details require referencing the Xilinx datasheet.
