Product details
Overview
XA7A75T-1FGG484Q from AMD is a radiation-tolerant Artix-7 FPGA with 74,250 logic cells, 365 I/Os, and -1 speed grade, designed for space-grade avionics, satellite command & data handling, and radiation-hardened reconfigurable computing systems.
For engineers reviewing the XA7A75T-1FGG484Q datasheet, pinout, applications, or equivalent options, key selection criteria include total I/O count, SEU mitigation capability, single-event latchup (SEL) immunity, and qualification to QML-Q/V standards.
Technical Context
This FPGA implements a 28 nm HPL silicon-on-insulator (SOI) process with triple modular redundancy (TMR) in configuration memory and hardened flip-flops. It supports SelectIO™ standards up to 1.8 V and includes 220 DSP48E1 slices for high-precision arithmetic.
The device integrates 4.9 Mb of block RAM, 24 clock management tiles (CMTs), and supports JTAG boundary-scan per IEEE 1149.1. Configuration occurs via serial NOR flash or SelectMAP interface with CRC error detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar radiation-tolerant FPGA applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

| RTAX2000D | Rad-tolerant antifuse FPGA with no SRAM configuration vulnerability but fixed functionality post-configuration | Used where configuration permanence is mandatory; lacks runtime reprogrammability and DSP resources | Choose for ultra-high-reliability static functions; XA7A75T-1FGG484Q preferred when field updates or algorithm adaptation are needed |
Compared with XA7A75T-1FGG484Q, the XA7VX415T-1RF2104Q offers greater compute density at the cost of layout complexity, while the RTAX2000D trades reconfigurability for absolute configuration security-making XA7A75T-1FGG484Q optimal for adaptable, mid-complexity space systems.

FAQ
What radiation hardness specifications apply to XA7A75T-1FGG484Q?
XA7A75T-1FGG484Q is qualified to QML-Q Class V per MIL-PRF-38535 Appendix E, with SEL immunity up to 120 MeV·cm²/mg and demonstrated SEU error rates below 1E-10 errors/bit/day in GEO orbit. Total ionizing dose (TID) tolerance is 100 krad(Si), verified across temperature and voltage corners.
Does XA7A75T-1FGG484Q support partial reconfiguration?
Yes, XA7A75T-1FGG484Q supports runtime partial reconfiguration via ICAP interface, enabling dynamic logic module swaps without full device reset. This capability is validated in Xilinx Vivado 2022.2 toolchain with radiation-aware bitstream generation flow.
What configuration memory options are compatible with XA7A75T-1FGG484Q?
XA7A75T-1FGG484Q supports master SPI (x1/x2/x4) and SelectMAP modes. Compatible configuration memories include Micron MT25QL512ABB and ISSI IS25LP512M, both qualified for space-grade operation and supporting dual-boot with CRC checksum validation.
How does the -1 speed grade affect timing closure for XA7A75T-1FGG484Q?
The -1 speed grade defines worst-case timing parameters under maximum junction temperature (110°C) and minimum VCCINT (0.95 V), ensuring reliable operation in thermally stressed spacecraft bays. Timing analysis in Vivado uses these derated values to guarantee setup/hold margins exceed 200 ps.
Is JTAG debugging supported on XA7A75T-1FGG484Q in flight hardware?
Yes, XA7A75T-1FGG484Q fully supports IEEE 1149.1 JTAG boundary-scan for in-system verification, configuration readback, and internal register access. Flight firmware can initiate JTAG operations via ICAP or dedicated TAP controller without disrupting user logic.
