AMD XC6SLX45-2FGG484C

Overview

XC6SLX45-2FGG484C from AMD (formerly Xilinx) is a Spartan-6 FPGA featuring 43,661 logic cells, 2,183 Kbits of block RAM, 180 DSP48A1 slices, and operates at -2 speed grade with 1.2 V core voltage. It is packaged in a 484-pin Fine-Pitch Ball Grid Array (FBGA) and used in industrial control, video processing, and embedded vision systems.

For engineers reviewing the XC6SLX45-2FGG484C datasheet, pinout, applications, or equivalent options, key selection considerations include I/O count (348 user I/Os), LVDS support, integrated clock management (DCM and PLL), and compatibility with Spartan-6 design tools and IP cores.

Technical Context

The XC6SLX45-2FGG484C implements a configurable logic fabric based on 6-input LUTs and flip-flops, with dedicated carry logic for arithmetic. It integrates dual-clock managers (DCMs) and phase-locked loops (PLLs) for clock synthesis, multiplication, division, and phase shifting across up to 16 output clocks.

It supports SelectIO standards including LVCMOS, LVTTL, HSTL, SSTL, and differential interfaces such as LVDS, Mini-LVDS, RSDS, and BLVDS. Configuration is performed via Master SPI, Slave Serial, or JTAG, with bitstream encryption available using AES-256.

FAQ

What is the maximum operating frequency of the XC6SLX45-2FGG484C?

The XC6SLX45-2FGG484C has a -2 speed grade, meaning its maximum guaranteed clock frequency for internal logic is 512 MHz for register-to-register paths and 375 MHz for block RAM read operations. Actual achievable frequency depends on design placement, routing, and resource utilization. The device's DCM and PLL support output frequencies up to 550 MHz under specific conditions.

Does the XC6SLX45-2FGG484C support JTAG configuration?

Yes, the XC6SLX45-2FGG484C supports JTAG boundary-scan configuration and debugging via the TCK, TMS, TDI, and TDO pins. This mode allows programming, verification, and in-circuit testing without requiring external configuration memory. JTAG is fully compliant with IEEE 1149.1 and supports daisy-chained devices.

What I/O standards are supported by the XC6SLX45-2FGG484C?

The XC6SLX45-2FGG484C supports 18 SelectIO standards including LVCMOS (1.2 V to 3.3 V), LVTTL, HSTL Class I/II, SSTL2 Class I/II, and differential standards such as LVDS, Mini-LVDS, RSDS, and BLVDS. Each I/O bank is independently configurable for voltage and standard, enabling mixed-voltage system interfacing.

Is the XC6SLX45-2FGG484C pin-compatible with other Spartan-6 devices in the FGG484 package?

XC6SLX45-2FGG484C shares the same 484-ball FGG484 package footprint and pinout with other Spartan-6 LX devices in that package, including XC6SLX25-2FGG484C and XC6SLX75-2FGG484C. However, I/O bank assignments and voltage requirements differ between densities, so schematic and PCB design must verify bank-specific constraints before substitution.

Can the XC6SLX45-2FGG484C perform partial reconfiguration?

Yes, the XC6SLX45-2FGG484C supports partial reconfiguration through its ICAP (Internal Configuration Access Port) interface. This allows dynamic loading of new configuration bitstreams into designated logic regions while the rest of the design remains operational-enabling runtime adaptation in communication protocols, filter coefficients, or control algorithms without system reset.
