The XC17256EDD8M is a 256K-bit Serial Configuration PROM (programmable read-only memory) from Xilinx. It's designed to store configuration data for Xilinx FPGAs (Field-Programmable Gate Arrays). These PROMs are essential for loading the programmed logic design into the FPGA upon power-up, enabling the FPGA to perform its intended function. The EDD8 designates the package type, which is a plastic dual-in-line.

Applications

• Configuration memory for Xilinx FPGAs
• Bootloaders for embedded systems
• Storage of firmware or software in electronic devices
• Data storage in applications where non-volatility is required
• Industrial control systems

Features

• 256K-bit storage capacity
• Serial interface for configuration data transfer
• Low power consumption
• Non-volatile memory (data retained without power)
• In-system programmability
• Enduring program storage (high reliability)

Benefits

• Easy FPGA configuration: Provides a simple and reliable method to configure Xilinx FPGAs.
• Reduced system complexity: Serial interface minimizes the number of pins required, simplifying board layout.

Additional Details

The XC17256EDD8M is a crucial component for systems utilizing Xilinx FPGAs. It provides a non-volatile storage solution for the FPGA configuration data, ensuring that the FPGA is properly initialized upon power-up. The serial interface simplifies the design process, reducing the number of required pins and minimizing board space. The PROM is designed for in-system programmability, allowing for easy updates and modifications to the FPGA configuration. The device is programmed using a Xilinx programmer. For detailed information regarding programming procedures, timing specifications, and electrical characteristics, refer to the official Xilinx datasheet for the XC17256E series. The reliability and enduring storage capability of this PROM are essential for ensuring the long-term stability and functionality of FPGA-based systems. The DD8 package type typically refers to a DIP (Dual In-line Package) with 8 leads. This part is considered obsolete and may be harder to source than newer configuration PROMs from Xilinx. The XC17256EDD8M ensures that the programmed logic design is reliably loaded into the FPGA upon power-up, enabling it to perform its intended functions in diverse applications, from telecommunications to industrial automation.
