AMD XC6SLX45-2FG676I

Overview

XC6SLX45-2FG676I from AMD (formerly Xilinx) is a Spartan-6 FPGA featuring 43,661 logic cells, 2,183 Kbits of block RAM, and 216 DSP48A1 slices, operating at -2 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 XC6SLX45-2FG676I datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (480 user I/Os), LVDS-compatible banks, single-ended signaling support, and configuration via SPI/BPI/JTAG interfaces.

Technical Context

The XC6SLX45-2FG676I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and dedicated carry logic. It supports multi-voltage I/O banks (1.2V/1.8V/2.5V/3.3V) and includes integrated clock management with DCMs for frequency synthesis and phase alignment.

Configuration is performed via Master Serial (SPI), Slave Serial, or Boundary Scan (JTAG) modes. The device supports bitstream encryption using AES-256 and configuration fallback for robust field updates.

Key Specifications

Pinout & Package

Supply support for XC6SLX45-2FG676I includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

AMD acquired Xilinx in 2022 and continues development and support of the Spartan-6 FPGA family. Xilinx pioneered programmable logic architecture and system-on-chip integration for embedded applications.

The Spartan-6 family was designed for cost-sensitive, high-volume applications requiring balanced logic density, I/O flexibility, and low-power operation-including industrial automation, video processing, and communications infrastructure.

FAQ

What is the maximum supported I/O standard for XC6SLX45-2FG676I?

The XC6SLX45-2FG676I supports LVDS, RSDS, BLVDS, SSTL, HSTL, and single-ended standards including LVTTL and LVCMOS across its 12 I/O banks. Each bank operates independently at 1.2V, 1.8V, 2.5V, or 3.3V, enabling mixed-voltage interface design without level shifters. This capability is documented in Xilinx UG381 v1.11.

Does XC6SLX45-2FG676I support partial reconfiguration?

Yes, XC6SLX45-2FG676I supports partial reconfiguration through the Xilinx ISE 14.7 toolflow using modular design methodology. This allows dynamic replacement of functional modules during operation-critical for adaptive systems like software-defined radios or reconfigurable test instruments-without resetting the entire device.

What configuration modes are available for XC6SLX45-2FG676I?

XC6SLX45-2FG676I supports Master Serial (SPI flash), Slave Serial, Slave SelectMAP, and JTAG configuration modes. Master Serial is most common for production systems due to its simplicity and integration with standard SPI NOR flash devices. JTAG is used for debugging and initial programming.

Is XC6SLX45-2FG676I RoHS compliant and lead-free?

Yes, XC6SLX45-2FG676I is RoHS compliant and features a lead-free, halogen-free FBGA package per Xilinx specification DS162 v3.2. The "I" suffix denotes Industrial temperature grade and also confirms compliance with JEDEC J-STD-020 moisture sensitivity level 3 (MSL3).

What clock management resources does XC6SLX45-2FG676I include?

XC6SLX45-2FG676I integrates two Digital Clock Managers (DCMs) per device. Each DCM provides frequency synthesis, phase shifting, duty cycle correction, and clock doubling/multiplication. These resources eliminate the need for external clock ICs in many timing-critical applications such as video pixel clock generation or ADC sampling synchronization.
