Product details
Overview
XA6SLX75T-3FGG484Q from AMD is a radiation-tolerant Spartan-6 FPGA with 74,880 logic cells, 3.2 Gb/s transceiver capability, and -3 speed grade, designed for spaceborne avionics data handling and on-board processing in LEO missions.
For engineers reviewing the XA6SLX75T-3FGG484Q datasheet, pinout, applications, or equivalent options, key selection factors include single-event latch-up (SEL) immunity, total ionizing dose (TID) rating, configuration memory scrubbing support, and QML-Q qualification status.
Technical Context
This FPGA implements a hierarchical architecture with Configurable Logic Blocks (CLBs), Block RAM (1,824 × 18 Kb), and DSP48E slices (180 units), all hardened against single-event effects per MIL-PRF-38535 Class Q requirements. It supports JTAG and SelectMAP configuration modes with CRC-based bitstream integrity checking.
The device integrates 24 multi-gigabit transceivers compliant with SpaceWire and LVDS protocols, each supporting programmable pre-emphasis and receiver equalization. Configuration memory includes SEU mitigation via built-in scrubbing controller and dual-redundant frame storage.

FAQ
What radiation hardness specifications apply to the XA6SLX75T-3FGG484Q?
The XA6SLX75T-3FGG484Q is qualified to 100 krad(Si) total ionizing dose and exhibits single-event latch-up immunity ≥ 75 MeV·cm²/mg per MIL-STD-883 TM1019.2. It undergoes lot-specific radiation lot acceptance testing (RLAT) and is certified QML-Q per MIL-PRF-38535.
Does the XA6SLX75T-3FGG484Q support configuration bitstream encryption?
No, the XA6SLX75T-3FGG484Q does not implement AES or other bitstream encryption. Its security model relies on physical access control and configuration authentication via CRC checksums. Secure boot requires external microcontroller coordination.
Can the XA6SLX75T-3FGG484Q be used in geostationary orbit (GEO) missions?
The XA6SLX75T-3FGG484Q is rated for 100 krad(Si) TID, sufficient for many GEO missions with shielding and mission duration ≤ 7 years. However, cumulative displacement damage and enhanced proton fluence may require additional derating analysis beyond standard QML-Q qualification limits.
What configuration modes are supported by the XA6SLX75T-3FGG484Q?
The XA6SLX75T-3FGG484Q supports Master Serial (JTAG), Slave SelectMAP, and Master SelectMAP configuration modes. It uses dedicated CONFIG_IO pins and includes internal pull-ups/pull-downs configurable via mode pins to set startup behavior without external biasing.
Is the XA6SLX75T-3FGG484Q pin-compatible with commercial Spartan-6 devices?
No, the XA6SLX75T-3FGG484Q uses a radiation-hardened IO structure, different voltage rail assignments, and QML-Q-specific thermal/mechanical packaging. Its pinout is compatible only within the XA6SLX75T family, not with commercial LX75 or LX150 variants.
