AMD’s Versal AI Core XQRVC1902 is a radiation-tolerant adaptive system-on-chip (SoC) designed for demanding space applications. It combines programmable logic, AI and digital signal processing (DSP) resources, embedded processors, memory, and high-speed interfaces so a spacecraft can process payload data onboard rather than sending every raw bit to Earth first. AMD targets it at onboard processing, digital payloads, and remote sensing; the public materials cited here do not identify a spacecraft mission that has flown this exact device.
What is the XQRVC1902?
XQRVC1902 is a specific device in AMD’s radiation-tolerant Versal AI Core XQR family. It is an adaptive SoC, not a standalone AI model or a complete spacecraft computer. Its components can be combined in a design to handle different kinds of computation and system tasks.
AMD’s Radiation Tolerant Versal AI Core Series Data Sheet (DS946), revision 1.2, released February 19, 2025, describes the device’s architecture, radiation parameters, package and pinout information, and ordering details.
- Programmable logic implements custom digital hardware and data-handling functions.
- AI Engine tiles and DSP engines provide resources for parallel vector, signal-processing, and inference workloads.
- Arm application and real-time processors run software, control, and other system tasks.
- Memory and fixed interfaces connect processing to data storage and other spacecraft components.
How can it be used in a spacecraft?
Consider a satellite instrument generating a large stream of imagery or radar data. A system designer can configure the XQRVC1902’s programmable logic and interfaces to receive and organize that stream, use AI or DSP resources for selected processing, and run control and software tasks on its embedded processors. The system can then pass selected results to another spacecraft subsystem or store data for later transmission. This is an explanation of how the documented architecture could fit a spacecraft data path, not a description of a named mission implementation.

AMD identifies onboard processing, digital payloads, and remote sensing as target applications. Its XQR Versal product brief also lists machine learning, cloud and object detection, broadband internet, high-speed networks, hyperspectral imaging, synthetic aperture radar, GPS/GNSS, and instrumentation. These are AMD’s stated applications, not independent evidence that the device has been deployed in each use.
Why process data onboard?
Processing near the instrument can let a spacecraft select, transform, or analyze data before it is sent to Earth. That can be useful when payloads produce high-volume data or when a mission needs onboard decision-making. The benefit a particular system achieves depends on its implemented hardware and software, interfaces, memory, power and thermal budgets, and mission design; the device’s resource counts alone do not establish a system’s throughput.

What does on-orbit reconfiguration mean?
AMD describes “unlimited on-orbit reconfiguration” for the XQR family, meaning its programmable logic is intended to be reconfigurable after launch. That capability can support changes to processing assignments or algorithms, subject to a mission’s validation and safety processes. It does not mean unlimited service life or that every configuration can be changed safely without testing.

What are the XQRVC1902’s key specifications?
Selected XQRVC1902 figures in AMD’s DS946 revision 1.2 feature table are shown below. These are device resource and interface specifications published by AMD in 2025, not benchmark results or measured spacecraft performance.
Rank #3
- Model Kit
- May Require Paints and Glues to Assemble
- Accurate Scale Model

- Decals/Transfers Included
| Resource or interface | AMD-listed specification |
|---|---|
| AI Engine tiles | 400 |
| DSP engines | 1,968 |
| Programmable-logic system cells | 1,968,400 |
| Look-up tables (LUTs) | 899,840 |

The processing system includes a dual-core Arm Cortex-A72 application processing unit and a dual-core Arm Cortex-R5F real-time processing unit. AMD also lists cache and ECC features, 256 KB of on-chip memory with ECC, and interfaces including Ethernet, UART, CAN-FD, USB 2.0, SPI, and I2C.
Actual application performance depends on the implemented design, software, memory configuration, interfaces, fault mitigation, thermal and power limits, and mission environment. The specification counts should not be read as a promised data rate or application benchmark.

What does radiation tolerant mean here?
AMD describes the XQR devices as radiation tolerant and says radiation effects are characterized for total ionizing dose and single-event effects. DS946 includes radiation parameter summaries and Weibull fits for tested components, including configuration RAM, block RAM, UltraRAM, the processor system, AI Engine, and XilSEM. The data sheet points to additional radiation reports on AMD’s Space Secure Site; its public material is not a mission-specific radiation assessment.
Radiation tolerant does not mean radiation proof or automatically suitable for every orbit, mission duration, or shielding design. A mission team must evaluate its radiation environment and dose, single-event behavior, shielding, redundancy, fault handling, and planned operating configuration. AMD’s product brief says “No external scrubber required” and that XilSEM meets LEO SEU mitigation requirements; those are AMD claims, not a universal recommendation for every orbit or mission profile.

What are the package and qualification details?
DS946 describes ruggedized lidless organic BGA packages, VSRA2197 and VSYA2197, with stiffener rings. Both are listed as 45 × 45 mm with 0.92 mm pitch. The VSRA version includes land-side capacitors and has a different center arrangement from the VSYA version. AMD lists military-temperature support from –55°C to +125°C and MIL-STD-883 group D qualification testing among the package features.
Package details in the data sheet should be distinguished from AMD’s October 1, 2026 announcement about an enhanced space-grade package. AMD said devices in that package were sampling with early-access customers and that testing to MIL-PRF-38535 Class Y was in progress. The announcement described support for missions lasting up to 15 years as a design aim; it did not report completed Class Y qualification.
Separately, DS946 lists the XQRVC1902 as production-released and names Vivado tools 2022.1 v2.08 as the minimum supported tool release. That product and software status does not establish that the newly announced enhanced package has completed its qualification process.

The XQRVC1902’s combination of programmable logic, AI and DSP resources, processors, memory, and interfaces makes it a configurable processing component for demanding payload and data-handling tasks. AMD’s materials document its intended space applications and device features, but they do not establish a particular flown spacecraft deployment or provide balanced head-to-head performance data against alternative space processors or FPGAs.
For a mission design, useful comparison criteria include radiation evidence for the target environment, qualification and screening status, usable compute resources, system-level power and thermal behavior, memory capacity and bandwidth, interfaces, fault recovery, reconfiguration needs, toolchain maturity, supply, and mission duration. A product’s resource counts or radiation-tolerant label alone cannot settle those system-level decisions.
