AMD XC3S5000-5FG676C

Overview

XC3S5000-5FG676C from AMD (formerly Xilinx) is a Spartan-3 FPGA with 5,093,760 system gates, 11,648 logic cells, and 3,584 Kbits of block RAM. It features 480 user I/Os, operates at -5 speed grade (equivalent to 333 MHz system clock), and uses a 676-pin Fine-Pitch Ball Grid Array (FBGA) package. It is deployed in industrial control systems requiring high-density programmable logic with deterministic timing.

For engineers reviewing the XC3S5000-5FG676C datasheet, pinout, applications, or equivalent options, key selection criteria include logic capacity, I/O count, speed grade, RAM depth, and FBGA676 thermal-mechanical compatibility with existing PCB layouts.

Technical Context

The XC3S5000-5FG676C implements a hierarchical architecture with configurable logic blocks (CLBs), distributed RAM, and dedicated multipliers. It supports SelectIO™ technology for interfacing with LVCMOS, LVTTL, SSTL, and HSTL standards across its 480 user I/Os.

This device integrates global clock networks with eight fully buffered clock lines and supports Digital Clock Managers (DCMs) for phase shifting, duty cycle correction, and frequency synthesis - enabling precise clock domain management in synchronous digital systems.

XC3S5000-5FG676C is available at Aetrix Electronics and suitable for industrial motion control, medical imaging interface, avionics data concentrators, and test & measurement equipment requiring stable component supply and long-term obsolescence planning.

Supply support for XC3S5000-5FG676C 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 acquired Xilinx in 2022 and now develops adaptive computing platforms including FPGAs, adaptive SoCs, and AI engines for heterogeneous compute acceleration.

The Spartan-3 family was originally designed by Xilinx for cost-effective, high-volume applications demanding substantial logic density and I/O flexibility in industrial and communications infrastructure.

FAQ

What is the maximum operating frequency supported by XC3S5000-5FG676C?

The XC3S5000-5FG676C is rated at speed grade -5, guaranteeing timing closure up to 333 MHz for system clock domains under worst-case voltage and temperature conditions. Actual achievable frequency depends on design placement, routing, and resource utilization - verified via Xilinx ISE timing analysis reports for the specific implemented bitstream.

Does XC3S5000-5FG676C support JTAG boundary-scan testing?

Yes, XC3S5000-5FG676C fully complies with IEEE 1149.1 (JTAG) standards. Its TCK, TMS, TDI, and TDO pins enable in-system programming, configuration verification, and board-level interconnect testing - all accessible without requiring external debug probes beyond standard JTAG adapters.

What power supply voltages does XC3S5000-5FG676C require?

XC3S5000-5FG676C requires two primary supplies: 1.2 V ±3% for the core logic (VCCINT) and configurable I/O bank voltages (VCCO) ranging from 1.2 V to 3.3 V per bank. Each VCCO bank must be independently regulated to match the signaling standard of connected peripherals.

Can XC3S5000-5FG676C be reconfigured in-system after power-up?

Yes, XC3S5000-5FG676C supports multiple in-system configuration modes including JTAG, master serial (via PROM), and slave selectMAP. The PROGRAM_B pin allows hardware-triggered reconfiguration without power cycle, enabling field-upgradable logic functionality during system operation.

Is XC3S5000-5FG676C compatible with Xilinx ISE Design Suite?

Yes, XC3S5000-5FG676C is fully supported by Xilinx ISE 14.7 - the final official release for Spartan-3 devices. Synthesis, place-and-route, bitstream generation, and timing analysis for XC3S5000-5FG676C are validated exclusively in this toolchain; newer Vivado software does not support this family.
