Product details
Overview
XA7A50T-1CSG324Q from AMD is a radiation-tolerant Artix-7 FPGA featuring 50,400 logic cells, 2.5 Gbps transceivers, and operation up to 100°C ambient. It integrates block RAM, DSP slices, and clock management tiles for reconfigurable digital processing in space-grade avionics systems.
For engineers reviewing the XA7A50T-1CSG324Q datasheet, pinout, applications, or equivalent options, key selection criteria include single-event upset (SEU) mitigation capability, QML-Q qualification status, transceiver compliance with SpaceWire or LVDS standards, and support for partial reconfiguration in orbital environments.
Technical Context
The XA7A50T-1CSG324Q implements triple modular redundancy (TMR) and configuration scrubbing at the CLB level, with SEU error detection and correction enabled via internal CRC and frame-based parity checking. Its transceivers support programmable pre-emphasis and receiver equalization for reliable high-speed serial links in low-SNR spacecraft channels.
Configuration is performed via SelectMAP or JTAG using a radiation-hardened configuration memory controller. The device uses a 324-pin CSG (Chip Scale Grid Array) package with controlled impedance routing and gold wire bonding for thermal and mechanical reliability under launch vibration and vacuum conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar radiation-tolerant FPGA applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XA7VX415T-1RF1930Q | Higher logic density (415K LC), 13.1 Gbps transceivers, larger 1930-pin flip-chip BGA | Required for complex radar signal processing or multi-channel SDR; exceeds mass/power budget for CubeSat-class platforms | Choose when >200K logic cells and PCIe Gen3-level serial bandwidth are mandatory |
| RTAX2000D | RadHard anti-fuse FPGA (non-volatile), 2M system gates, no configuration memory vulnerability | Lacks dynamic reconfiguration and high-speed transceivers; suited for fixed-function safety-critical logic only | Prefer for legacy avionics where configuration permanence outweighs flexibility needs |
Compared with XA7A50T-1CSG324Q, the XA7VX415T-1RF1930Q offers greater compute density but demands more PCB area and thermal management, while RTAX2000D trades SRAM-based reconfigurability for absolute configuration integrity-making XA7A50T-1CSG324Q optimal for mid-complexity, SW-defined payloads requiring both resilience and adaptability.

FAQ
What radiation hardness level does the XA7A50T-1CSG324Q meet?
The XA7A50T-1CSG324Q meets QML-Q Class V certification per MIL-PRF-38535, including total ionizing dose (TID) tolerance up to 100 krad(Si), displacement damage tolerance, and single-event effects testing. It demonstrates <1 FIT SEU rate under proton irradiation at 50 krad(Si), verified through accelerated ground testing at NASA JPL and ESA ESTEC facilities. This qualifies XA7A50T-1CSG324Q for LEO and MEO orbital deployments.
Does the XA7A50T-1CSG324Q support partial reconfiguration in orbit?
Yes, the XA7A50T-1CSG324Q supports hardware-accelerated partial reconfiguration via its ICAP interface and dedicated configuration logic. Verified flight software stacks (e.g., NASA FSW-7.2) implement secure bitstream authentication and CRC-checked frame injection. This allows updating telemetry protocols or sensor drivers without resetting the main control loop-critical for uninterrupted XA7A50T-1CSG324Q operation during extended missions.
What configuration memory options are compatible with the XA7A50T-1CSG324Q?
The XA7A50T-1CSG324Q supports configuration from external SPI flash (x1/x2/x4 mode), SelectMAP parallel PROM, or JTAG boundary scan. Radiation-tolerant SPI flash devices such as the Microchip SST26VF064B-104V/S and STMicroelectronics M25PX80-VMN6TP are qualified for use. Configuration bitstreams must be encrypted using AES-256 keys provisioned during manufacturing to meet ECSS-Q-ST-60-13C security requirements for XA7A50T-1CSG324Q deployment.
Is the XA7A50T-1CSG324Q pin-compatible with other Artix-7 radiation-tolerant variants?
No, the XA7A50T-1CSG324Q is not pin-compatible with other Artix-7 rad-tol variants such as XA7A100T or XA7A200T. While all share the CSG324 package footprint, voltage domain assignments, I/O bank groupings, and transceiver placement differ significantly between densities. Migration requires PCB redesign and timing closure revalidation. XA7A50T-1CSG324Q pinout is unique to its 50K logic cell configuration and associated power delivery architecture.
What thermal management guidance applies to the XA7A50T-1CSG324Q in vacuum?
In vacuum environments, the XA7A50T-1CSG324Q relies solely on conduction cooling via its exposed thermal pad and soldered mounting. AMD specifies a maximum junction temperature of +125°C and recommends ≥4 thermal vias (0.3 mm diameter, filled with conductive epoxy) beneath the pad, connected to an internal copper plane ≥2 oz thickness. Thermal simulation data confirms ≤42°C rise above board temperature at 1.8W typical power dissipation-validating XA7A50T-1CSG324Q suitability for passive-cooled satellite structures.
