AMD XC6SLX100-N3CSG484C

Overview

XC6SLX100-N3CSG484C from AMD (formerly Xilinx) is a Spartan-6 FPGA featuring 101,261 logic cells, 18 Kbits block RAM per block, 180 DSP48A1 slices, and operates at -3 speed grade with commercial temperature range (0°C to 85°C). It is used in industrial vision systems for real-time image preprocessing and interface bridging.

For engineers reviewing the XC6SLX100-N3CSG484C datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (348 user I/Os), LVCMOS/LVTTL/SSTL interface support, embedded clock management (DCM and PLL), and configuration via SPI/BPI/master serial modes.

Technical Context

The XC6SLX100-N3CSG484C implements a configurable logic fabric based on 6-input LUTs and flip-flops, with dedicated carry logic and shift registers. It integrates dual 18×18 multipliers per DSP48A1 slice and supports distributed RAM up to 32 bits deep per LUT.

Configuration is performed through SelectMAP, serial, or JTAG interfaces, with bitstream encryption optional via AES-256. Clock routing includes global, regional, and I/O clocks, managed by two DCMs and one PLL per device.

Key Specifications

Pinout & Package

XC6SLX100-N3CSG484C is housed in a 484-pin CSG (Chip Scale Grid Array) package with 25 mm × 25 mm body size, 0.8 mm pitch, and Pb-free/ROHS-compliant finish.

FAQ

What is the maximum supported I/O standard voltage for XC6SLX100-N3CSG484C?

XC6SLX100-N3CSG484C supports I/O standards up to 3.3 V, including LVCMOS33, LVTTL, and SSTL2. Each of its 12 I/O banks is independently configurable for voltages ranging from 1.2 V to 3.3 V, enabling mixed-voltage system interfacing without level shifters. The VCCO supply for each bank must match the selected IOSTANDARD's voltage requirement, and XC6SLX100-N3CSG484C does not support 5 V-tolerant inputs.

Does XC6SLX100-N3CSG484C include built-in configuration memory?

No, XC6SLX100-N3CSG484C does not include on-chip nonvolatile configuration memory. It requires an external serial PROM (e.g., XCFxx series) or flash memory for master serial configuration. Configuration is loaded on power-up via dedicated CONFIG_IO pins, and XC6SLX100-N3CSG484C supports fallback mechanisms such as dual-image storage and CRC verification to ensure robust boot reliability.

Can XC6SLX100-N3CSG484C operate in industrial temperature ranges beyond 85°C?

XC6SLX100-N3CSG484C is rated for commercial temperature range only (0°C to +85°C). It is not qualified for extended industrial (-40°C to +100°C) or automotive operation. Operating XC6SLX100-N3CSG484C above +85°C may cause timing violations, configuration loss, or permanent damage. For higher ambient environments, thermal derating and forced-air cooling must be validated per Xilinx UG380 guidelines specific to XC6SLX100-N3CSG484C.

How many clock management tiles does XC6SLX100-N3CSG484C contain?

XC6SLX100-N3CSG484C contains two Digital Clock Managers (DCMs) and one Phase-Locked Loop (PLL). These are distributed across the die and support independent clock synthesis, frequency multiplication/division, phase shifting, and duty-cycle correction. All three clock resources are accessible to logic fabric and I/O banks, and XC6SLX100-N3CSG484C allows concurrent use of DCM outputs and PLL outputs for multi-domain clocking schemes.

Is XC6SLX100-N3CSG484C pin-compatible with other Spartan-6 devices in the CSG484 package?

XC6SLX100-N3CSG484C shares the same CSG484 package footprint and pinout with XC6SLX75, XC6SLX150, and XC6SLX150T in the same speed grade and temperature range. However, I/O bank assignments and dedicated function pin mappings (e.g., DCM inputs, configuration pins) differ across densities. Direct replacement without design review is not guaranteed - XC6SLX100-N3CSG484C requires verification of bank-specific VCCO, IOSTANDARD, and pin-function compatibility before substitution.
