AMD XC6SLX100T-N3FG676C

Overview

XC6SLX100T-N3FG676C from AMD (formerly Xilinx) is a Spartan-6 FPGA featuring 101,280 logic cells, 4,729 Kbits of block RAM, 220 DSP48A1 slices, and operates at -3 speed grade with commercial temperature range (0°C to 85°C). It is used in industrial control systems requiring deterministic I/O timing and partial reconfiguration support.

For engineers reviewing the XC6SLX100T-N3FG676C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O bank voltage flexibility (1.2V/1.8V/2.5V/3.3V), LVDS/BLVDS differential signaling capability, and integrated clock management with six DCMs and one PLL.

Technical Context

The XC6SLX100T-N3FG676C implements a configurable logic fabric based on 6-input LUTs and flip-flops, with dedicated carry logic for arithmetic functions. It supports SelectIO™ technology enabling single-ended and differential standards including SSTL, HSTL, LVCMOS, and LVDS across 12 I/O banks.

Its clocking architecture includes six Digital Clock Managers (DCMs) supporting phase shifting, frequency synthesis, and duty cycle correction, plus one PLL for higher-frequency multiplication and jitter reduction. Configuration is performed via Master Serial, Slave Serial, or JTAG modes using external SPI flash or processor-controlled interfaces.

FAQ

What is the maximum operating frequency of the XC6SLX100T-N3FG676C?

The XC6SLX100T-N3FG676C is rated at speed grade -3, guaranteeing timing closure up to 500 MHz for internal logic paths under worst-case commercial conditions (0°C to 85°C, VCCINT = 1.2 V ±3%). Actual achievable frequency depends on design complexity, routing, and I/O standard selection.

Does the XC6SLX100T-N3FG676C support partial reconfiguration?

Yes, the XC6SLX100T-N3FG676C supports partial reconfiguration through its ICAP interface and hierarchical design flow in ISE Design Suite. This allows dynamic replacement of logic modules without resetting the entire device, enabling runtime protocol adaptation in communication gateways and test instrumentation.

What configuration modes does the XC6SLX100T-N3FG676C support?

The XC6SLX100T-N3FG676C supports Master Serial (SPI flash), Slave Serial (host processor-driven), and JTAG configuration modes. Each mode uses distinct pin assignments and initialization sequences, with M0–M2 pins selecting the active mode during power-up.

Can the XC6SLX100T-N3FG676C interface directly with DDR2 memory?

Yes, the XC6SLX100T-N3FG676C supports DDR2 SDRAM interfaces via its SelectIO™ banks configured for SSTL-18 I/O standard. It includes dedicated DQS capture circuitry and phase-aligned clocking through DCM outputs to meet DDR2 timing requirements up to 400 Mbps data rate.

Is the XC6SLX100T-N3FG676C RoHS compliant?

Yes, the XC6SLX100T-N3FG676C is RoHS compliant and manufactured with lead-free packaging. The FG676 package uses matte tin finish on solder balls and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements.
