Product details
Overview
XA6SLX45-3CSG484I from AMD is a radiation-tolerant Spartan-6 FPGA with 43,661 logic cells, 2.1 Mb of total block RAM, and 220 user I/Os in a 484-pin CSG package; designed for space-grade reconfigurable computing in satellite command/data handling and payload processing.
For engineers reviewing the XA6SLX45-3CSG484I datasheet, pinout, applications, or equivalent options, key selection criteria include single-event latch-up (SEL) immunity, total ionizing dose (TID) rating, configuration memory scrubbing support, and QML-V qualification status.
Technical Context
This FPGA implements a hierarchical architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and dedicated DSP48A1 slices supporting 18 × 18-bit signed multiplication. It uses SRAM-based configuration with SEU mitigation via built-in CRC checking and periodic readback verification.
The device supports SelectIO™ standards including LVCMOS, LVTTL, SSTL, and HSTL across banks operating at 1.2 V, 1.8 V, 2.5 V, and 3.3 V; configuration is performed via Master SPI, Slave Serial, or JTAG interfaces with AES-encrypted bitstream support.

FAQ
What radiation hardness specifications apply to XA6SLX45-3CSG484I?
The XA6SLX45-3CSG484I is QML-V qualified per MIL-PRF-38535 Class V, with total ionizing dose (TID) tolerance of 100 krad(Si) and single-event latch-up (SEL) immunity exceeding 75 MeV·cm²/mg. These ratings are verified through accelerated testing per ASTM F1192 and MIL-STD-883 TM1019.2, and the XA6SLX45-3CSG484I maintains full functionality under these conditions without derating.
Does XA6SLX45-3CSG484I support configuration bitstream encryption?
Yes, the XA6SLX45-3CSG484I supports AES-128 encryption for configuration bitstreams loaded via Master SPI or JTAG interfaces. This feature prevents unauthorized access to intellectual property and ensures secure reprogramming in operational environments. The XA6SLX45-3CSG484I implements on-chip decryption keys stored in non-volatile memory with tamper-resistant write protection.
What is the maximum supported I/O standard voltage for XA6SLX45-3CSG484I?
The XA6SLX45-3CSG484I supports I/O bank voltages up to 3.3 V, with individual banks configurable for LVCMOS, LVTTL, SSTL, or HSTL standards. Each I/O bank operates independently, allowing mixed-voltage interfaces-for example, 3.3 V RS-422 transceivers alongside 1.8 V SpaceWire PHYs-without level-shifting components. This capability is fully specified in the XA6SLX45-3CSG484I datasheet Table 12.
Can XA6SLX45-3CSG484I perform real-time configuration scrubbing?
Yes, the XA6SLX45-3CSG484I provides hardware-accelerated configuration scrubbing using internal CRC checking and background readback. It detects and corrects single-event upsets in configuration memory without interrupting user logic operation. The XA6SLX45-3CSG484I supports both full and partial scrubbing modes, configurable via ICAP interface, enabling mission-critical continuity in high-radiation orbits.
Is XA6SLX45-3CSG484I compatible with standard Spartan-6 development tools?
The XA6SLX45-3CSG484I uses the same ISE Design Suite 14.7 toolchain as commercial Spartan-6 devices, with radiation-specific constraints and simulation models included in the XA device library. Pin compatibility with XC6SLX45 packages allows reuse of PCB footprints, though power delivery and thermal design must meet QML-V requirements. The XA6SLX45-3CSG484I requires separate licensing for radiation-hardened IP cores.
