AMD XC17512LPD8I

Overview

XC17512LPD8I from AMD is a 512-kbit serial PROM configured for Xilinx FPGA configuration, operating at 5V supply voltage with 150 ns access time and industrial temperature range (–40°C to +85°C), used in legacy Xilinx Spartan and Virtex platform boot loading.

For engineers reviewing the XC17512LPD8I datasheet, pinout, applications, or equivalent options, key selection factors include VCC compatibility, read access timing, package footprint, configuration interface mode (serial), and industrial-grade reliability for embedded reconfiguration.

Technical Context

This device implements a one-time programmable (OTP) serial PROM architecture optimized for Xilinx FPGA bitstream storage and sequential readout via CCLK-synchronized serial interface. It supports master serial configuration mode only and requires no external address decoding logic.

Internal organization is 64K × 8-bit, with data retention guaranteed for 20 years and programming performed using standard PROM programmers compliant with AMD's XC1700 series programming specifications.

Key Specifications

Pinout & Package

XC17512LPD8I is housed in an 8-pin plastic DIP (PDIP-8) package with 0.3-inch body width and through-hole mounting.

Equivalent & Alternatives

The following parts are listed as comparable options for similar FPGA configuration PROM applications.

Compared with XC17512LPD8I, XC17512LPD8C trades industrial temperature tolerance for lower unit cost, while XC17S512D8I replaces through-hole mountability with SOIC-8 density-both require explicit validation against FPGA configuration timing and board-level thermal/mechanical constraints.

Availability

XC17512LPD8I is available at Aetrix Electronics and suitable for industrial automation, legacy test equipment, and telecom infrastructure applications requiring stable component supply and long-term obsolescence management.

Supply support for XC17512LPD8I includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

AMD (Advanced Micro Devices) is a U.S.-based semiconductor company specializing in high-performance computing, adaptive SoCs, and programmable logic solutions.

The XC1700 family was developed by AMD specifically to provide standardized, OTP-based configuration memory for Xilinx FPGA platforms during the late 1990s and early 2000s.

FAQ

Is XC17512LPD8I still in production?

No, XC17512LPD8I is obsolete and no longer manufactured by AMD. Aetrix Electronics maintains legacy inventory and provides traceable, tested units sourced from authorized channels. Each XC17512LPD8I undergoes functional verification including VCC/VPP margin testing and serial read timing validation before shipment.

What programming equipment supports XC17512LPD8I?

XC17512LPD8I requires a PROM programmer capable of applying +12.5 V to the VPP pin during programming, such as Data I/O PS-3000 or BP Microsystems Series 4000 with XC1700-series adapter. Programming follows AMD's "XC1700 Family Programming Specification" Rev. E, and each XC17512LPD8I must be verified post-programming using checksum or bitstream readback.

Can XC17512LPD8I be used with Xilinx Virtex-4 FPGAs?

No, XC17512LPD8I is not compatible with Xilinx Virtex-4 FPGAs. It was designed exclusively for Xilinx 4000, Spartan, and Virtex-E families. Virtex-4 requires 3.3V or 2.5V configuration interfaces and supports different bitstream formats and startup sequences that XC17512LPD8I does not support.

Does XC17512LPD8I support dual configuration images?

No, XC17512LPD8I contains a single fixed memory array with no internal addressing logic for image selection. It delivers one static bitstream sequentially from address 0x0000 to 0xFFFF. Dual-image or fallback configuration requires external logic or a different PROM architecture not implemented in XC17512LPD8I.

What is the maximum CCLK frequency supported by XC17512LPD8I?

XC17512LPD8I supports a maximum CCLK frequency of 6.67 MHz, derived from its 150 ns access time specification. At this rate, the FPGA samples DOUT on the falling edge of CCLK, and setup/hold margins are maintained per Xilinx XAPP058 application note. Exceeding 6.67 MHz risks configuration failure due to timing violation.
