XC17256ELPC20C

XC17256ELPC20C Description

The XC17256ELPC20C is a 256Kb (32K x 8) One-Time Programmable (OTP) configuration memory device from AMD, designed for use with FPGAs and other programmable logic. Housed in a 20-pin PLCC (Plastic Leaded Chip Carrier) surface-mount package, this IC operates within a 3V to 3.6V supply range and is rated for commercial temperature (0°C to 70°C) environments. As an obsolete product, it remains relevant for legacy systems requiring reliable, non-volatile storage for FPGA configuration data. Its OTP architecture ensures data integrity, making it ideal for applications where reprogrammability is unnecessary.

XC17256ELPC20C Features

• Memory Capacity: 256Kb (32K x 8) for efficient storage of FPGA bitstreams.
• OTP (One-Time Programmable): Ensures secure, tamper-proof configuration data storage.
• Wide Voltage Range: Operates at 3V–3.6V, compatible with low-power FPGA systems.
• Surface-Mount PLCC Package: 20-pin design for compact PCB integration.
• Commercial Temperature Range: Suitable for 0°C to 70°C environments.
• Moisture Sensitivity Level (MSL 3): Requires baking if exposed beyond 168 hours.
• REACH & RoHS Compliance: Environmentally friendly with no restricted substances.

XC17256ELPC20C Applications

This device is optimized for FPGA configuration storage, particularly in legacy or industrial systems where reliability is critical. Key applications include:

• Industrial Control Systems: Stores configuration for FPGA-based automation controllers.
• Telecommunications Equipment: Provides boot code for network hardware.
• Medical Devices: Ensures secure, unalterable firmware storage.
• Military/Aerospace (obsolete designs): Used in older systems requiring OTP security.
• Embedded Systems: Ideal for single-use programmable logic setups.

Conclusion of XC17256ELPC20C

The XC17256ELPC20C offers a robust, high-reliability OTP memory solution for FPGA configuration, particularly in legacy designs. Its 3.3V operation, compact PLCC package, and commercial-grade temperature tolerance make it suitable for industrial, telecom, and embedded applications. While marked obsolete, it remains a dependable choice for systems requiring secure, one-time programmable memory without the need for updates. Engineers working with older FPGA platforms will find this device a practical option for stable, long-term configuration storage.
