Product details
Overview
XC6SLX45-L1CSG484I 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 CSGA package with -1 speed grade and industrial temperature range (-40°C to +100°C). It serves as a reconfigurable logic fabric for embedded control, video processing, and communication interface bridging in space-constrained industrial systems.
For engineers reviewing the XC6SLX45-L1CSG484I datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (348 user I/Os), LVDS support, SelectIO™ voltage compatibility (1.2 V to 3.3 V), and integrated clock management via DCMs.
Technical Context
The XC6SLX45-L1CSG484I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and dedicated carry logic. It integrates six Digital Clock Managers (DCMs) supporting phase shifting, frequency synthesis, and duty cycle correction across multiple clock domains.
It supports source-synchronous interfaces including DDR2 SDRAM (up to 800 Mbps), PCI Express® Gen1 (x1 lane), and Gigabit transceivers are absent - this device belongs to the LX non-transceiver family. Configuration occurs via Master SPI, Slave Parallel, or JTAG modes using external PROM or processor-controlled loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Cells | 43,661 - determines maximum combinational/sequential logic capacity for custom state machines or protocol engines |
| Block RAM | 2,125 kbits - enables on-chip buffering for video frame stores, FIFOs, or lookup tables without external memory |
| DSP Slices | 216 × DSP48A1 - supports fixed-point multiply-accumulate operations at up to 250 MHz for filtering or motor control |
| User I/O Pins | 348 - provides high-density parallel interface capability for sensors, displays, or FMC mezzanine connectivity |
| DCMs | 6 × Digital Clock Manager - delivers jitter-tolerant clock synthesis and phase alignment for multi-clock domain designs |
| Speed Grade | -1 - guarantees timing closure up to 667 Mbps I/O toggle rate and 500 MHz internal logic performance |
| Temp Range | -40°C to +100°C - qualified for extended-temperature industrial and transportation equipment deployment |
Pinout & Package
XC6SLX45-L1CSG484I is housed in a 484-ball fine-pitch CSP (Chip Scale Grid Array) package, designated CSG484, with 0.8 mm ball pitch and Pb-free RoHS-compliant finish. The package supports thermal dissipation up to 3.5 W under typical industrial operating conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCO_0 | I/O bank power supply | Configures voltage level (1.2–3.3 V) for Bank 0 I/Os; must match connected peripheral interface standard |
| CLKIN | Primary clock input | Accepts single-ended or differential clocks up to 320 MHz; feeds DCM for internal clock generation |
| PROG_B | Configuration reset | Active-low signal that clears configuration memory and initiates reconfiguration sequence |
| INIT_B | Configuration status | Open-drain output indicating configuration completion or error during bitstream loading |
| TCK/TMS/TDI/TDO | JTAG boundary-scan interface | Enables IEEE 1149.1-compliant programming, debugging, and interconnect testing |
Key Features
| Feature | Design Value |
|---|---|
| SelectIO™ Technology | Supports 18 I/O standards including LVCMOS, LVTTL, SSTL, HSTL, and differential signaling (LVDS, RSDS) - enables direct interfacing with diverse memory and peripheral ICs |
| Dedicated Memory Controller | Hardened logic for DDR2 SDRAM interfaces up to 400 MHz data rate - reduces RTL design effort and timing closure risk for memory subsystems |
| Embedded Block RAM | 2.1 Mb distributed across 112 dual-port RAM blocks - allows independent read/write access for pipeline buffering or dual-clock FIFO implementation |
| Multi-Standard Transceivers (absent) | This device has no high-speed serial transceivers - simplifies PCB layout and power delivery versus transceiver-equipped variants like XC6SLX45T |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based logic acceleration applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC6SLX45-2CSG484C | Faster -2 speed grade; commercial temperature range (0°C to +85°C); identical logic resources and I/O count | Suitable for lab-grade or non-extended-temp environments where higher timing margin is required | Select when design requires >667 Mbps I/O toggle rates or operates within commercial ambient conditions |
| XC6SLX25-L1CSG324I | Smaller footprint (324-ball), reduced logic (24,051 cells), lower block RAM (1,824 kbits), same -1 speed grade and industrial temp range | Better fit for cost-sensitive, lower-complexity control applications with fewer I/O requirements | Choose when design fits within 218 user I/Os and does not require >2.1 Mb on-chip memory |
Compared with XC6SLX45-L1CSG484I, the XC6SLX45-2CSG484C offers higher timing margin but lacks industrial temperature qualification, while XC6SLX25-L1CSG324I trades logic density and I/O count for smaller size and lower cost - both require PCB redesign due to different packages and pinouts.

No, XC6SLX45-L1CSG484I does not include high-speed serial transceivers. It belongs to the Spartan-6 LX non-transceiver family. For transceiver functionality, designers must select an XC6SLX45T variant or move to Spartan-6 LXT devices - XC6SLX45-L1CSG484I relies solely on parallel I/O and SelectIO™ for interface connectivity.
What configuration modes are supported by XC6SLX45-L1CSG484I?
XC6SLX45-L1CSG484I supports three primary configuration modes: Master SPI (using on-chip oscillator), Slave Parallel (with external processor control), and JTAG (for programming and debugging). All modes are fully documented in Xilinx UG380 and function identically across all Spartan-6 LX devices including XC6SLX45-L1CSG484I.
Is XC6SLX45-L1CSG484I RoHS compliant and lead-free?
Yes, XC6SLX45-L1CSG484I is RoHS compliant and features a lead-free, halogen-free package with matte tin finish on the CSG484 balls. This compliance is specified in Xilinx PDN-XA-0003 and confirmed for the industrial-grade CSG484 packaging used in XC6SLX45-L1CSG484I.
How many Digital Clock Managers (DCMs) are available in XC6SLX45-L1CSG484I?
XC6SLX45-L1CSG484I contains six Digital Clock Managers (DCMs), each capable of frequency synthesis, phase shifting, and duty cycle correction.
