AMD XC6SLX100T-N3CSG484C

Overview

XC6SLX100T-N3CSG484C from AMD (formerly Xilinx) is a Spartan-6 FPGA featuring 101,280 logic cells, 484-pin CSBGA package, -3 speed grade, and industrial temperature range (–40°C to +100°C). It integrates 18 Kb block RAM, 24 DSP48A1 slices, and supports LVDS, SSTL, HSTL I/O standards for high-speed interface design in embedded vision systems.

For engineers reviewing the XC6SLX100T-N3CSG484C datasheet, pinout, applications, or equivalent options, key selection criteria include logic capacity, I/O voltage flexibility, embedded memory depth, DSP resource count, and industrial-grade thermal reliability.

Technical Context

The XC6SLX100T-N3CSG484C implements a configurable logic fabric based on 6-input LUTs and flip-flops, with dedicated carry logic for arithmetic. It includes dual-port 18 Kb block RAM with byte-write enable and parity support, and 24 hard-wired DSP48A1 slices capable of 18×25 signed multiplication with 48-bit accumulator output.

I/O banks are organized into eight groups supporting independent VCCO voltages (1.2 V to 3.3 V), with programmable slew rate, drive strength, and on-die termination. Configuration occurs via Master SPI or JTAG, with bitstream encryption supported through AES-128.

Key Specifications

Pinout & Package

FAQ

What is the maximum supported I/O standard voltage for XC6SLX100T-N3CSG484C?

XC6SLX100T-N3CSG484C supports I/O standards from 1.2 V to 3.3 V across its eight independently powered I/O banks. Each bank's VCCO can be set to any value in that range, enabling mixed-voltage interfaces such as 3.3 V sensors and 1.8 V processors on the same device. The VCCAUX supply must be maintained at 2.5 V ±5% for proper configuration and clock circuit operation.

Does XC6SLX100T-N3CSG484C include built-in configuration memory?

No, XC6SLX100T-N3CSG484C does not include on-chip nonvolatile configuration memory. It requires external serial flash (e.g., SPI NOR) for master SPI configuration or JTAG for programming and debugging. Bitstream loading occurs at power-up via dedicated configuration pins (M0, M1, M2), and AES-128 decryption is applied during read-from-flash load if enabled.

Can XC6SLX100T-N3CSG484C operate in extended temperature environments beyond industrial grade?

No, XC6SLX100T-N3CSG484C is qualified only for the industrial temperature range of –40°C to +100°C. It is not rated for automotive (–40°C to +125°C) or military-grade extremes. Operation outside this range may result in timing violations, configuration loss, or permanent damage. Derating is not supported per Xilinx DS162 specification.

How many clock management tiles does XC6SLX100T-N3CSG484C contain?

XC6SLX100T-N3CSG484C contains two Digital Clock Managers (DCMs), each providing frequency synthesis, phase shifting, duty cycle correction, and jitter reduction. These DCMs accept single-ended or differential inputs and support up to 32 distinct output frequencies per tile. No PLLs are present - clocking relies exclusively on DCM architecture in the Spartan-6 family.

Is XC6SLX100T-N3CSG484C compatible with Xilinx ISE Design Suite?

Yes, XC6SLX100T-N3CSG484C is fully supported by Xilinx ISE Design Suite 14.7, the final and only official toolchain for Spartan-6 devices. Vivado does not support Spartan-6 FPGAs. ISE provides synthesis, implementation, simulation, and bitstream generation specifically validated for XC6SLX100T-N3CSG484C timing models and package constraints.
