AMD XC6SLX45T-3FG484I

Overview

XC6SLX45T-3FG484I from AMD (formerly Xilinx) is a Spartan-6 FPGA featuring 43,661 logic cells, 2.1 Mb of block RAM, 186 DSP48A1 slices, and operates at -3 speed grade with industrial temperature range (-40°C to +100°C). It is used in industrial control systems requiring deterministic I/O timing and partial reconfiguration support.

For engineers reviewing the XC6SLX45T-3FG484I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (348 user I/Os), LVDS/PCIe-compatible transceivers, and support for JTAG boundary-scan and SelectMAP configuration interfaces.

Technical Context

The XC6SLX45T-3FG484I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and dedicated carry logic. It supports multi-standard I/O banks with programmable drive strength, slew rate, and on-chip termination (up to 150 Ω).

This device integrates six CMT clock management tiles-each containing two DCMs and one PLL-for low-jitter clock synthesis, phase shifting, and frequency synthesis across multiple domains. It supports DDR2/DDR3 memory interfaces up to 800 Mbps data rate.

FAQ

What is the maximum supported DDR3 data rate for XC6SLX45T-3FG484I?

The XC6SLX45T-3FG484I supports DDR3 interfaces up to 800 Mbps per data line using its dedicated memory controller logic and I/O timing calibration. This capability is validated in Xilinx UG388 and applies specifically to the -3 speed grade under industrial temperature conditions. The XC6SLX45T-3FG484I achieves this through calibrated delay elements and source-synchronous strobe alignment.

Does XC6SLX45T-3FG484I support partial reconfiguration in production systems?

Yes, the XC6SLX45T-3FG484I supports runtime partial reconfiguration via ICAP interface, enabling dynamic logic module swaps without full device reset. This feature is documented in Xilinx UG380 and has been deployed in fielded industrial controllers. The XC6SLX45T-3FG484I requires specific bitstream partitioning and configuration controller firmware to implement secure partial reconfiguration.

What configuration modes are supported by XC6SLX45T-3FG484I?

The XC6SLX45T-3FG484I supports Master SPI, Slave SPI, SelectMAP, and JTAG configuration modes. These are implemented via dedicated pins (M0–M2, PROGRAM_B, INIT_B, CCLK, DIN/DOUT) and verified in Xilinx UG380. The XC6SLX45T-3FG484I allows fallback to JTAG for recovery if primary SPI flash fails during boot.

Is XC6SLX45T-3FG484I compatible with Xilinx ISE 14.7?

Yes, the XC6SLX45T-3FG484I is fully supported in Xilinx ISE Design Suite 14.7, including synthesis, place-and-route, and bitstream generation. This compatibility is confirmed in the ISE 14.7 release notes and device support files. Projects targeting the XC6SLX45T-3FG484I can be developed and maintained exclusively within the ISE environment.

What is the I/O standard compatibility of XC6SLX45T-3FG484I?

The XC6SLX45T-3FG484I supports LVCMOS, LVTTL, SSTL, HSTL, LVDS, RSDS, and TMDS I/O standards across its 12 I/O banks. Each bank is independently configurable for voltage (1.2 V to 3.3 V) and termination. This flexibility is specified in Xilinx DS162 and enables direct interfacing with diverse peripherals without level-shifting components.
