Product details
Overview
XC6SLX45-3FG484C from AMD (formerly Xilinx) is a Spartan-6 FPGA with 43,661 logic cells, 2,183 Kbits of block RAM, and 186 user I/Os in a 484-pin Fine-Pitch Ball Grid Array (FBGA) package. It operates at -3 speed grade (fastest in Spartan-6 family) and supports 1.2 V core voltage for low-power embedded control and industrial interface applications.
For engineers reviewing the XC6SLX45-3FG484C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count, speed grade timing closure, block RAM depth for buffering, and compatibility with Spartan-6 design tools and configuration interfaces.
Technical Context
The XC6SLX45-3FG484C implements a fully programmable logic fabric based on 6-input LUTs and distributed RAM, with integrated DSP48A1 slices supporting 18×18-bit multiply-accumulate operations. It includes dedicated clock management tiles with DCMs (Digital Clock Managers) for frequency synthesis and phase alignment.
Configuration is performed via Master SPI or JTAG, with support for fallback dual-image bitstreams. The device integrates SelectIO™ technology enabling LVCMOS, LVDS, and SSTL I/O standards across its 186 user pins, with programmable drive strength and slew rate control per bank.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Cells | 43,661 - determines maximum combinational/sequential logic capacity for custom digital functions |
| Block RAM | 2,183 Kbits - provides on-chip memory for FIFOs, buffers, or small lookup tables without external memory |
| User I/Os | 186 - supports high-density peripheral interfacing with bank-wise voltage and standard flexibility |
| Speed Grade | -3 - guarantees worst-case timing performance at highest operating frequency in Spartan-6 family |
| Core Voltage | 1.2 V ±3% - defines power delivery requirements and impacts dynamic/static power consumption |
| Package | 484-pin FBGA (F/G suffix) - 23×23 mm body, 1.0 mm ball pitch, RoHS-compliant, requires reflow assembly |
Pinout & Package
XC6SLX45-3FG484C uses a 484-ball fine-pitch BGA (package code FG484) with 186 user-configurable I/Os distributed across 10 I/O banks. Power and ground balls are allocated per bank to minimize noise coupling; configuration pins (e.g., INIT_B, PROGRAM_B, DONE) and dedicated clock inputs (e.g., CLKIN_0, CLKIN_1) are fixed-function and non-reconfigurable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PROGRAM_B | Active-Low Configuration Initiate | Asserting low triggers full reconfiguration from external SPI flash or host processor |
| INIT_B | Open-Drain Status Output | Indicates configuration memory clearing status; pulled high during normal operation |
| DONE | Open-Drain Configuration Completion | Drives high when bitstream loading and startup sequence complete successfully |
| CLKIN_0 / CLKIN_1 | Dedicated Single-Ended Clock Inputs | Feed DCMs for internal clock generation; require 0–350 MHz input range and proper termination |
| VCCO_0–VCCO_9 | I/O Bank Supply Voltages | Set output voltage level and compatible I/O standards per bank (e.g., 3.3 V, 2.5 V, 1.8 V) |
Key Features
| Feature | Design Value |
|---|---|
| DCM-based clock management | Enables precise clock multiplication, division, phase shifting, and jitter reduction without external PLL ICs |
| SelectIO™ technology | Allows mixed-voltage I/O operation across banks, supporting legacy and modern interface standards simultaneously |
| DSP48A1 slices | Delivers deterministic 18×18-bit signed multiplication with 48-bit accumulator for real-time filtering or motor control |
| Embedded Block RAM | Provides true dual-port RAM with independent read/write clocks per block, usable as FIFO or buffer memory |
| MultiBoot configuration | Supports up to two independent bitstreams stored in SPI flash, enabling field-upgradable firmware with fallback safety |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic implementation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC6SLX45-2FG484C | Slower -2 speed grade; ~15% lower max clock frequency in timing-critical paths | Suitable for cost-sensitive designs where full -3 timing margin is not required | Select when system-level timing slack allows relaxed setup/hold margins and lower power consumption is prioritized |
| XC6SLX75-3FG484C | Higher logic density (74,637 LUTs), +30% block RAM, same package footprint and pinout | Used when additional logic resources or larger on-chip memory buffers are needed for expanded functionality | Choose for scalable designs requiring headroom for future feature upgrades without PCB revision |
Compared with XC6SLX45-3FG484C, the -2 variant trades speed for lower static power and cost, while the XC6SLX75-3FG484C offers pin-compatible scalability-both retain identical I/O banking structure and configuration interface, enabling reuse of board layout and firmware infrastructure.

FAQ
What is the maximum operating frequency supported by XC6SLX45-3FG484C?
The XC6SLX45-3FG484C supports a maximum system clock frequency of 750 MHz for internal logic paths under worst-case conditions, as guaranteed by its -3 speed grade. This applies to critical timing paths routed through LUTs and registers; actual achievable frequency depends on design complexity, placement, and routing. The DCMs support input frequencies up to 350 MHz and can generate higher-frequency clocks internally.
Does XC6SLX45-3FG484C support JTAG boundary-scan testing?
Yes, XC6SLX45-3FG484C includes IEEE 1149.1-compliant JTAG TAP controller for boundary-scan testing, programming, and debug access. All 186 user I/Os support INTEST and EXTEST instructions, and the TDO pin is dedicated for scan-out. JTAG is active during and after configuration, enabling in-system verification without halting operation.
Can XC6SLX45-3FG484C be configured using a microcontroller?
Yes, XC6SLX45-3FG484C supports master serial (SPI) configuration mode, allowing an external microcontroller to load the bitstream from attached flash memory. The microcontroller controls PROGRAM_B and monitors INIT_B/DONE to manage configuration sequencing. No additional level-shifting is required if both devices share compatible I/O voltages.
What I/O standards are supported by XC6SLX45-3FG484C?
XC6SLX45-3FG484C supports LVCMOS (1.2 V to 3.3 V), LVDS, Mini-LVDS, RSDS, BLVDS, and SSTL (I and II) standards across its 10 I/O banks. Each bank is independently configurable for voltage and standard, but all pins in a bank must use the same VCCO. Differential standards require adjacent pin pairing and proper termination.
Is XC6SLX45-3FG484C qualified for automotive applications?
No, XC6SLX45-3FG484C is not AEC-Q100 qualified and is not recommended for automotive safety-critical systems. It is rated for commercial (0°C to +85°C) and industrial (-40°C to +100°C) temperature ranges. For automotive use, AMD offers the Spartan-6Q family with extended temperature and qualification support-XC6SLX45-3FG484C does not meet those requirements.
