AMD XC6SLX45-2FGG484I

Overview

XC6SLX45-2FGG484I from AMD (formerly Xilinx) is a Spartan-6 FPGA with 43,661 logic cells, 2.1 Mb of block RAM, and 216 DSP48A1 slices, configured in a 484-pin Fine-Pitch Ball Grid Array (FBGA) package with industrial temperature range (–40°C to +100°C). It targets embedded vision preprocessing, industrial I/O bridging, and protocol conversion in space-constrained control systems.

For engineers reviewing the XC6SLX45-2FGG484I datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (348 user I/Os), speed grade (-2 = 500 MHz system clock capability), LVDS/PCIe Gen1 support, and industrial-grade thermal reliability.

Technical Context

The XC6SLX45-2FGG484I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and dedicated carry logic. It supports SelectIO standards including LVCMOS, LVTTL, LVDS, and differential SSTL, with programmable slew rate and drive strength per bank.

It integrates dual 10-bit ADCs for on-chip monitoring, six CMT clock management tiles (each with DCM and PLL), and supports JTAG, SPI, and BPI configuration modes. The -2 speed grade guarantees timing closure at 500 MHz for critical paths under industrial temperature conditions.

Key Specifications

Pinout & Package

Compared with XC6SLX45-2FGG484I, the XC6SLX45-3FGG484C offers higher clock frequency headroom but sacrifices industrial temperature compliance, while the XC7S50-2FTG256I delivers architectural improvements and power efficiency at the cost of I/O density and toolchain continuity.

Availability

XC6SLX45-2FGG484I is available at Aetrix Electronics and suitable for industrial motion control, embedded vision preprocessing, and protocol translation gateway applications requiring stable component supply across extended product lifecycles.

Supply support for XC6SLX45-2FGG484I 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 maintains the Spartan-6 product family for long-lifecycle industrial and aerospace applications.

The Spartan-6 family was designed for cost-sensitive, high-reliability embedded systems requiring predictable timing, low static power, and mature toolchain support - especially where ISE-based designs remain in production.

FAQ

What is the maximum supported I/O standard voltage for XC6SLX45-2FGG484I?

The XC6SLX45-2FGG484I supports I/O standards from 1.2 V to 3.3 V across its 12 I/O banks, with per-bank voltage selection. Each bank can be independently configured for LVCMOS12, LVCMOS15, LVCMOS18, LVCMOS25, LVCMOS33, LVTTL, or differential standards like LVDS and SSTL. This flexibility allows mixed-voltage interfacing without level-shifters in XC6SLX45-2FGG484I-based systems.

Does XC6SLX45-2FGG484I include built-in analog-to-digital converters?

Yes, XC6SLX45-2FGG484I integrates two 10-bit, 1 MSPS auxiliary analog-to-digital converters (XADC) for monitoring on-die temperature and supply voltages (VCCINT, VCCAUX, VCCO). These ADCs operate independently of the FPGA fabric and require no external components, enabling real-time health monitoring in XC6SLX45-2FGG484I deployments without adding discrete sensors.

What configuration modes does XC6SLX45-2FGG484I support?

XC6SLX45-2FGG484I supports Master Serial (SPI x1/x2/x4), Slave Serial, Master SelectMAP (BPI x8/x16), Slave SelectMAP, and JTAG configuration modes. Bitstream loading can be initiated via PROGRAM_B, and status verified using INIT_B and CONFIG_DONE pins. All modes are fully documented in Xilinx UG380 for XC6SLX45-2FGG484I and compatible with industrial flash memory devices.

Is XC6SLX45-2FGG484I pin-compatible with other Spartan-6 devices in the same package?

No, XC6SLX45-2FGG484I is not fully pin-compatible with other Spartan-6 FPGAs in the FGG484 package, such as XC6SLX16 or XC6SLX100. While the physical footprint and ball map match, I/O bank assignments, configuration pin locations, and dedicated function pin mappings differ. Migration requires PCB layout verification and pin assignment review per UG381 for each specific XC6SLX45-2FGG484I variant.

What is the guaranteed operating temperature range for XC6SLX45-2FGG484I?

XC6SLX45-2FGG484I is rated for industrial temperature operation from –40°C to +100°C ambient, with full functionality and timing compliance across this range. This specification is validated per JEDEC JESD22-A104 and applies to all logic, I/O, clocking, and configuration resources. Thermal derating is not required for XC6SLX45-2FGG484I within these limits when used with appropriate PCB copper pour and airflow.
