Product details
Overview
XA7A35T-1CSG324Q from AMD is a radiation-tolerant Artix-7 FPGA featuring 35,000 logic cells, 2.1 Mb of block RAM, 186 DSP slices, and operation up to 628 MHz in -1 speed grade; used in spaceborne data processing units requiring single-event latch-up immunity and TID tolerance to 100 krad(Si).
For engineers reviewing the XA7A35T-1CSG324Q datasheet, pinout, applications, or equivalent options, key selection criteria include SEU mitigation capability, QML-Q/QML-V qualification status, I/O voltage support (1.2–3.3 V), and configuration via SelectMAP or JTAG.
Technical Context
The XA7A35T-1CSG324Q implements triple modular redundancy (TMR) in CLBs and hardened configuration memory with CRC error detection. It integrates 24 transceivers supporting 6.6 Gb/s serial links and includes dedicated PCIe Gen2 x2 endpoint logic.
Configuration is performed through SEU-hardened configuration memory with automatic scrubbing; power management supports dynamic voltage and frequency scaling (DVFS) across three I/O banks and two internal voltage domains (VCCINT, VCCAUX).

Equivalent & Alternatives
The following parts are listed as comparable options for similar radiation-tolerant FPGA applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XA7A50T-1CSG324Q | 50K logic cells, identical package and radiation specs; higher static power and larger die area | Preferred when additional logic resources needed for multi-channel sensor processing or redundant control paths | Select when design requires >35K LUTs without changing PCB layout or thermal design |
| RTAX2000D | Rad-tolerant antifuse FPGA; non-reprogrammable, lower I/O count (171), no transceivers | Better for ultra-high-reliability boot ROM or fixed-function control where reconfiguration is not required | Choose only if field updates are unnecessary and deterministic timing outweighs flexibility needs |
Compared with XA7A35T-1CSG324Q, the XA7A50T-1CSG324Q offers scalable logic density within identical mechanical and radiation constraints, while RTAX2000D trades reprogrammability for absolute configuration permanence-critical for fail-safe boot functions but limiting for adaptive mission phases.

FAQ
What radiation hardness specifications apply to the XA7A35T-1CSG324Q?
The XA7A35T-1CSG324Q is qualified to 100 krad(Si) total ionizing dose (TID), exhibits no single-event latch-up (SEL) up to 110 MeV·cm²/mg, and incorporates SEU-hardened configuration memory with scrubbing. These ratings are verified per ESA/SCC 22900 and MIL-STD-883 TM1019 test methods, and documented in the official AMD XA7A35T-1CSG324Q qualification report.
Does the XA7A35T-1CSG324Q support partial reconfiguration?
Yes, the XA7A35T-1CSG324Q supports partial reconfiguration through its hardened configuration logic and frame-based bitstream architecture. This allows dynamic module swapping in operational systems-such as updating telemetry encoding logic without resetting the entire FPGA fabric-while maintaining radiation tolerance and configuration integrity throughout the process.
What configuration modes does the XA7A35T-1CSG324Q support?
The XA7A35T-1CSG324Q supports JTAG, Master SPI, Slave SelectMAP, and BPI parallel modes. Mode selection is controlled by M0–M2 pins at power-on reset. All modes retain full SEU immunity in configuration memory, and JTAG remains accessible for debug even after radiation exposure.
Is the XA7A35T-1CSG324Q pin-compatible with commercial Artix-7 devices?
No, the XA7A35T-1CSG324Q uses a radiation-hardened I/O structure and hardened configuration circuitry that differ electrically and functionally from commercial Artix-7 parts. While the CSG324 package footprint matches, voltage tolerances, drive strength, and configuration signaling are not interchangeable-requiring dedicated board design and validation.
What thermal management guidance applies to the XA7A35T-1CSG324Q in vacuum environments?
In vacuum, the XA7A35T-1CSG324Q relies on conduction cooling through its exposed thermal pad and solder-ball array. AMD specifies a maximum junction temperature of 100°C and recommends copper-filled thermal vias under the package, direct metal mounting, and thermal interface material compliant with NASA ASTM E595 outgassing limits for sustained operation.
