Product details
Overview
XC6SLX45T-4CSG484C from AMD (formerly Xilinx) is a Spartan-6 FPGA featuring 43,661 logic cells, 2.7 Mb of total block RAM, 180 DSP48A1 slices, and operates at -4 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 XC6SLX45T-4CSG484C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (348 user I/Os), LVDS-compatible banks, SelectIO™ voltage support (1.2 V to 3.3 V), and compatibility with Xilinx ISE Design Suite v14.7.
Technical Context
The XC6SLX45T-4CSG484C implements a configurable logic fabric based on 6-input LUTs and flip-flops, with dedicated carry logic for arithmetic. It integrates dual-register 18×18 multipliers in each DSP48A1 slice and supports DDR2/DDR3 memory interfaces up to 800 Mbps.
Configuration is performed via Master Serial SPI or JTAG, with bitstream encryption and fallback support. The device includes integrated clock management using DCMs (Digital Clock Managers) with phase shifting, frequency synthesis, and duty cycle correction across eight independent clock regions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based control and interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC6SLX45-4FGG484C | No transceivers; identical logic resources, same package but FGG = Fine-Pitch BGA (not chip-scale); lacks GTP transceiver support | Suitable for non-serial-interface applications where transceivers are unused; lower cost where CSG thermal performance not required | Select XC6SLX45-4FGG484C only if transceivers are unnecessary and board layout accommodates larger 23×23 mm FGG footprint |
| XC7S50-2CSGA324C | Artix-7 architecture; 52,000 logic cells, 2.5 Mb BRAM, no DCMs (uses MMCMs), -2 speed grade, smaller 324-pin CSGA package | Better DSP density and higher-speed I/O (up to 1.0 Gbps), but requires Vivado toolchain and lacks Spartan-6 ISE compatibility | Choose XC7S50-2CSGA324C for new designs needing higher bandwidth or future-proof tool support; avoid for ISE-maintained legacy systems |
Compared with XC6SLX45-4FGG484C, the XC6SLX45T-4CSG484C offers superior thermal dissipation and transceiver-ready I/O banks; versus XC7S50-2CSGA324C, it retains ISE toolchain compatibility and deterministic DCM-based clocking for legacy industrial firmware.

FAQ
What is the maximum supported memory interface speed for XC6SLX45T-4CSG484C?
The XC6SLX45T-4CSG484C supports DDR2 SDRAM interfaces up to 400 MHz (800 Mbps data rate) and DDR3 interfaces up to 400 MHz (800 Mbps) using dedicated I/O logic and DCM-based clock forwarding. These speeds are validated under industrial temperature conditions with appropriate PCB layout and termination.
Does XC6SLX45T-4CSG484C support partial reconfiguration in production systems?
Yes, XC6SLX45T-4CSG484C supports runtime partial reconfiguration through Xilinx ISE 14.7 with PlanAhead tools. This capability has been deployed in fielded industrial PLCs for updating motion control algorithms without halting machine operation or resetting I/O states.
What configuration modes does XC6SLX45T-4CSG484C support?
XC6SLX45T-4CSG484C supports Master Serial (SPI flash), Slave Serial, JTAG, and Boundary Scan configuration modes. Master Serial is most commonly used for standalone boot; JTAG is preferred for debugging and programming during development and field service.
Is XC6SLX45T-4CSG484C pin-compatible with other Spartan-6 devices in the CSG484 package?
XC6SLX45T-4CSG484C shares the same CSG484 mechanical footprint and I/O bank structure with XC6SLX25T-4CSG484C and XC6SLX75T-4CSG484C, but logic resource allocation and certain dedicated pin functions (e.g., GTP transceiver locations) differ. Full pin compatibility requires verification against UG382 v1.11 for each variant.
What is the core voltage requirement for XC6SLX45T-4CSG484C?
XC6SLX45T-4CSG484C requires a nominal 1.2 V ±3% core supply (VCCINT) delivered to dedicated power pins. This voltage powers the FPGA fabric, CLBs, and interconnect; deviation beyond tolerance risks timing violation or configuration failure, especially at -4 speed grade and industrial temperature extremes.
