Product details
Overview
XA6SLX45T-3FGG484Q from AMD is a radiation-tolerant Spartan-6 FPGA with 43,661 logic cells, 2.1 Mb of block RAM, and support for LVDS I/O up to 1.0 Gbps. It operates across -40°C to +105°C and is qualified for space-grade applications including satellite command & data handling and onboard processing.
For engineers reviewing the XA6SLX45T-3FGG484Q datasheet, pinout, applications, or equivalent options, key selection criteria include single-event latchup (SEL) immunity, total ionizing dose (TID) rating, configuration memory scrubbing capability, and QML-Q/V qualification status.
Technical Context
The XA6SLX45T-3FGG484Q implements a reconfigurable logic fabric based on 6-input LUTs and distributed RAM, with dedicated DSP48A1 slices supporting 18×18-bit multiply-accumulate operations. It integrates dual 10-bit ADCs and supports SelectIO standards including LVCMOS, SSTL, HSTL, and differential LVDS.
Configuration is performed via Master Serial or Slave SelectMAP modes using external PROM or processor-controlled interface. Built-in SEU mitigation includes CRC-based configuration frame checking and periodic readback with bitstream correction logic.

FAQ
What is the radiation qualification level of XA6SLX45T-3FGG484Q?
The XA6SLX45T-3FGG484Q is qualified to QML-Q per MIL-PRF-38535, with total ionizing dose (TID) tolerance of 100 krad(Si) and single-event latchup (SEL) immunity ≥ 80 MeV·cm²/mg. These ratings are verified through lot-specific testing and documented in the official AMD QML-Q certificate for this part number.
Does XA6SLX45T-3FGG484Q support configuration scrubbing?
Yes, the XA6SLX45T-3FGG484Q includes hardware-assisted configuration scrubbing with CRC frame checking and automatic bitstream correction. This feature continuously monitors and repairs configuration memory against single-event upsets, maintaining functional integrity in high-radiation orbits.
What I/O standards are supported by XA6SLX45T-3FGG484Q?
The XA6SLX45T-3FGG484Q supports LVCMOS, SSTL, HSTL, and differential LVDS I/O standards. Its LVDS interfaces operate up to 1.0 Gbps and are compliant with SpaceWire physical layer timing requirements for spacecraft data networks.
Is XA6SLX45T-3FGG484Q pin-compatible with commercial Spartan-6 devices?
No, the XA6SLX45T-3FGG484Q uses a radiation-hardened process and QML-Q screening that result in different electrical characteristics and thermal behavior. While the pinout matches the commercial FG484 package footprint, voltage tolerances, drive strength, and timing margins are not interchangeable without redesign validation.
What configuration modes does XA6SLX45T-3FGG484Q support?
The XA6SLX45T-3FGG484Q supports Master Serial, Slave SelectMAP, and JTAG configuration modes. Master Serial is commonly used with external PROM, while Slave SelectMAP allows processor-controlled partial reconfiguration for adaptive mission tasks.
