Product details
Overview
XA6SLX75-2CSG484Q from AMD is a radiation-tolerant Spartan-6 FPGA with 74,880 logic cells, 3.2 Gb/s transceiver capability, and -2 speed grade, deployed in space-grade avionics for on-board data processing and reconfigurable I/O control.
For engineers reviewing the XA6SLX75-2CSG484Q datasheet, pinout, applications, or equivalent options, key selection factors include radiation tolerance (100 krad(Si) TID), SEU mitigation architecture, extended temperature range (-55°C to +125°C), and QML-Q qualified packaging.
Technical Context
The XA6SLX75-2CSG484Q implements a hardened configuration memory with triple modular redundancy (TMR) and built-in scrubbing logic to sustain operation in high-radiation environments. It integrates 324 DSP48E1 slices for real-time signal processing and supports SelectIO™ standards up to 1.25 Gbps per pin.
Configuration is performed via serial or parallel mode using dedicated CCLK, DIN, and INIT_B pins; bitstream authentication is not supported. The device uses a 484-pin Ceramic Column Grid Array (CPGA) package with controlled impedance routing for space-qualified PCBs.

FAQ
What radiation hardness specifications apply to the XA6SLX75-2CSG484Q?
The XA6SLX75-2CSG484Q is qualified to 100 krad(Si) total ionizing dose (TID) and demonstrates single-event upset (SEU) mitigation via triple modular redundancy and hardware scrubbing. It meets MIL-STD-883 method 1019.8 for heavy-ion testing with LET threshold ≥ 37 MeV·cm²/mg. These ratings are verified per QML-Q flow and documented in the official AMD XA Spartan-6 qualification report.
Does the XA6SLX75-2CSG484Q support JTAG configuration?
Yes, the XA6SLX75-2CSG484Q supports IEEE 1149.1 JTAG boundary-scan and configuration through TCK, TMS, TDI, and TDO pins. JTAG mode enables in-system programming, debug access, and verification of configuration integrity. The XA6SLX75-2CSG484Q does not support JTAG streaming of user logic; configuration remains bitstream-based.
What is the meaning of the 'Q' suffix in XA6SLX75-2CSG484Q?
The 'Q' suffix in XA6SLX75-2CSG484Q denotes QML-Q certification per MIL-PRF-38535 Class Q, indicating full qualification for spaceflight use with lot traceability, extended screening, and radiation testing. It distinguishes this part from commercial or industrial variants and confirms compliance with NASA EEE-INST-002 and ESA ESCC basic specification requirements.
Can the XA6SLX75-2CSG484Q operate at full speed across its entire temperature range?
Yes, the XA6SLX75-2CSG484Q is fully characterized and guaranteed to meet -2 speed grade timing specifications from -55°C to +125°C. This includes setup/hold timing, I/O delay, and internal propagation delays. No derating is required for thermal extremes, enabling reliable operation in uncontrolled satellite thermal environments.
Is the XA6SLX75-2CSG484Q pin-compatible with any non-radiation-hardened Spartan-6 devices?
No, the XA6SLX75-2CSG484Q is not pin-compatible with standard Spartan-6 FPGAs such as XC6SLX75-2CSG484C. Differences include dedicated radiation-hardened power sequencing pins, modified configuration pin behavior, and ceramic CPGA vs. plastic CSBGA packaging. PCB layout must be designed specifically for the XA6SLX75-2CSG484Q.
