The XC17512LSC is a 512Kbit In-System Programmable Read-Only Memory (ISP PROM) configuration memory device from Xilinx, primarily used for configuring Xilinx FPGAs (Field-Programmable Gate Arrays). These PROM devices store the configuration bitstream that determines the functionality of the FPGA. The XC17512LSC is designed for applications needing non-volatile storage of FPGA configuration data.

Applications

• Configuration memory for Xilinx FPGAs
• Storage of configuration data in embedded systems
• Boot memory for systems requiring non-volatile data storage
• Industrial control systems
• Telecommunications equipment

Features

• 512 Kbits of storage capacity
• In-System Programmable (ISP) via serial interface
• Low power consumption
• High endurance (number of program/erase cycles)
• Fast access time
• Available in various package options, including SOIC
• Operates from a single 5V supply

Benefits

• Non-volatile storage: Retains configuration data even when power is removed.
• In-System Programmable: Allows for easy updates and reconfiguration of the FPGA without removing the device from the board.
• Low power consumption: Suitable for power-sensitive applications.
• High endurance: Ensures reliable operation over the lifetime of the device.
• Fast access time: Enables quick configuration of the FPGA at startup.
• Flexibility: Programmability offers design flexibility and adaptability.

The XC17512LSC is programmed through a serial interface, typically using a Xilinx programming cable and software. The configuration data is loaded into the PROM and stored in non-volatile memory cells. When the FPGA is powered on, it reads the configuration data from the PROM and configures itself accordingly. The device supports multiple programming and erase cycles, allowing for frequent updates to the FPGA configuration. It is designed to operate reliably over a wide temperature range. Careful consideration of signal integrity and power supply decoupling is recommended for optimal performance.
