AMD XC3S1000-5FGG320C

Overview

XC3S1000-5FGG320C from AMD (formerly Xilinx) is a Spartan-3 FPGA with 1,000,000 system gates, 17,280 logic cells, and 432 I/O pins in a 320-pin Fine-Pitch Ball Grid Array (FBGA) package. It operates at -5 speed grade (100 MHz system clock), supports SelectIO™ standards including LVCMOS, LVTTL, and SSTL, and targets high-volume embedded control and digital signal processing applications.

For engineers reviewing the XC3S1000-5FGG320C datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, I/O count, speed grade, package thermal profile, and compatibility with Xilinx ISE design tools and Spartan-3 configuration interfaces.

Technical Context

The XC3S1000-5FGG320C implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, block RAM (48 × 18 Kbit), and dedicated multipliers (18 × 18). It uses SRAM-based configuration with external PROM or processor-controlled loading via JTAG or master serial mode.

It supports differential signaling (LVDS, RSDS) on selected I/O banks, includes Digital Clock Managers (DCMs) for clock synthesis and phase alignment, and features internal global clock networks with low skew for synchronous timing closure up to 100 MHz.

FAQ

What is the maximum operating frequency supported by XC3S1000-5FGG320C?

The XC3S1000-5FGG320C is rated for a -5 speed grade, guaranteeing timing closure at 100 MHz system clock frequency under worst-case industrial temperature and voltage conditions. Actual achievable frequency depends on design topology, routing, and resource usage - verified through Xilinx ISE static timing analysis.

Does XC3S1000-5FGG320C support JTAG programming?

Yes, XC3S1000-5FGG320C supports IEEE 1149.1 JTAG boundary-scan programming and debugging via dedicated TCK, TMS, TDI, and TDO pins. Configuration can be performed in-circuit using Xilinx iMPACT or compatible tools without requiring external PROM.

What power supplies are required for XC3S1000-5FGG320C operation?

XC3S1000-5FGG320C requires three independent supplies: 1.2 V for core logic (VCCINT), 2.5 V for auxiliary circuits and DCMs (VCCAUX), and bank-specific 1.8–3.3 V for I/O (VCCO). Each supply must meet ripple, sequencing, and decoupling requirements specified in DS099.

How many Digital Clock Managers (DCMs) does XC3S1000-5FGG320C include?

XC3S1000-5FGG320C integrates four fully functional Digital Clock Managers (DCMs). Each DCM provides clock multiplication, division, phase shifting, and duty cycle correction - enabling precise clock domain management without external PLL ICs.

Is XC3S1000-5FGG320C compatible with Xilinx ISE Design Suite?

Yes, XC3S1000-5FGG320C is fully supported by Xilinx ISE 14.7 and earlier versions. Synthesis, place-and-route, bitstream generation, and timing analysis workflows are validated for this device in the ISE toolchain.
