AMD XC6SLX75-3FG484I

Overview

XC6SLX75-3FG484I from AMD (formerly Xilinx) is a Spartan-6 FPGA with 74,880 logic cells, 3.2 Gb/s transceiver capability, and embedded Block RAM totaling 3,001 kbits. It operates at -3 speed grade (fastest in Spartan-6 family) and supports LVDS, SSTL, and HSTL I/O standards. It is used in industrial video processing systems requiring deterministic latency and multi-channel pixel data handling.

For engineers reviewing the XC6SLX75-3FG484I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O voltage flexibility (1.2 V to 3.3 V), distributed RAM depth per slice (16 bits), and DCI termination support for impedance-matched signaling in high-speed parallel interfaces.

Technical Context

The XC6SLX75-3FG484I implements a hierarchical FPGA architecture with six-input LUTs, dedicated carry logic, and integrated DSP48A1 slices supporting 18×18-bit multiply-accumulate operations. It includes dual-clock FIFO primitives and hard-wired PCI Express® Endpoint logic compliant with Gen1 x1 configuration.

Configuration is supported via Master SPI, Slave SelectMAP, or JTAG, with bitstream encryption enabled through AES-128 key storage in on-chip eFUSE. The device uses 40 nm CMOS process technology and supports partial reconfiguration for dynamic function swapping without full system reset.

FAQ

What is the maximum operating junction temperature for XC6SLX75-3FG484I?

The XC6SLX75-3FG484I has a maximum operating junction temperature of 100°C, validated for continuous operation across the industrial temperature range (-40°C to +100°C). This rating applies under specified thermal conditions with appropriate PCB copper pour and airflow. The XC6SLX75-3FG484I thermal resistance (θ_JA) is 22.5°C/W in standard 4-layer board layout, ensuring reliability in fanless enclosures.

Does XC6SLX75-3FG484I support partial reconfiguration in production systems?

Yes, XC6SLX75-3FG484I supports certified partial reconfiguration through Xilinx ISE Design Suite 14.7 and later versions. The XC6SLX75-3FG484I allows dynamic swapping of logic modules while preserving I/O states and internal RAM contents, enabling field-upgradable functions such as protocol adaptation or algorithm updates without system reboot.

Can XC6SLX75-3FG484I interface directly with DDR2 SDRAM at 400 MHz?

Yes, XC6SLX75-3FG484I supports DDR2 SDRAM interfaces up to 400 MHz data rate (200 MHz clock) using its dedicated DQS capture logic and SSTL-18 I/O standard. The XC6SLX75-3FG484I includes built-in write leveling and read leveling calibration support in MIG v3.93, meeting JEDEC DDR2-400 timing specifications with ±15 ps skew control.

Is bitstream encryption enabled by default on XC6SLX75-3FG484I?

No, bitstream encryption is not enabled by default on XC6SLX75-3FG484I. It requires explicit AES-128 key programming into on-chip eFUSE using Xilinx iMPACT or Vivado tools. Once programmed, the XC6SLX75-3FG484I enforces encrypted configuration loading, rejecting unencrypted bitstreams and preventing unauthorized readback of configuration memory.

What configuration modes does XC6SLX75-3FG484I support?

XC6SLX75-3FG484I supports three primary configuration modes: Master SPI (internal oscillator drives serial flash), Slave SelectMAP (external processor controls parallel bitstream load), and JTAG (boundary-scan and debug). The XC6SLX75-3FG484I also supports fallback configuration from secondary SPI flash if primary fails, enhancing system robustness in unattended deployments.
