Product details
Overview
XA7A50T-1CPG236Q from AMD is a radiation-tolerant Artix-7 FPGA with 50K logic cells, 2.5 Gbps transceivers, and -1 speed grade in a 236-pin CP (Chip Scale Package) with 0.8 mm pitch. It operates across -40°C to 125°C and supports SEU mitigation via configuration scrubbing - deployed in spaceborne payload controllers and onboard data processors.
For engineers reviewing the XA7A50T-1CPG236Q datasheet, pinout, applications, or equivalent options, key selection factors include radiation tolerance level (up to 100 krad(Si)), single-event latch-up immunity, configuration memory scrub rate, and transceiver compliance with SpaceWire or LVDS protocols.
Technical Context
This FPGA implements a 28 nm HPL silicon process with hardened configuration memory and triple modular redundancy (TMR) support for critical logic. It integrates 240 DSP48E1 slices, 280 block RAMs (each 36 Kb), and 12 clock management tiles with MMCM/PLL for jitter-controlled clock synthesis.
The device supports JTAG boundary-scan (IEEE 1149.1), SelectMAP, and serial configuration modes. Configuration bitstream integrity is enforced via CRC checking and automatic reconfiguration on error detection - essential for unattended long-duration missions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar radiation-tolerant FPGA applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XA7A35T-1CPG236Q | 35K logic cells, identical package and radiation specs, lower transceiver count (4 vs. 8) | Lower gate count limits complex telemetry preprocessing; suitable for simpler command-and-control roles | Select when system logic density requirement is ≤35K LUTs and cost optimization is prioritized |
| RTAX2000D | Rad-Hard anti-fuse FPGA (no SRAM configuration), 2M system gates, QFP352 package | No configuration scrubbing needed but no field reprogrammability; fixed functionality post-deployment | Choose for ultra-high reliability where reconfiguration is not required and legacy design reuse is critical |
Compared with XA7A50T-1CPG236Q, the XA7A35T-1CPG236Q offers identical radiation performance in a smaller logic footprint, while RTAX2000D trades reprogrammability for permanent configuration stability - guiding selection based on mission duration, update requirements, and algorithm complexity.

FAQ
What radiation hardness specifications apply to the XA7A50T-1CPG236Q?
The XA7A50T-1CPG236Q is characterized for total ionizing dose (TID) tolerance up to 100 krad(Si), single-event latch-up (SEL) immunity above 75 MeV·cm²/mg, and single-event upset (SEU) mitigation via configurable scrubbing. These values are verified per MIL-STD-883 TM1019.2 and ESA ESCC 22900 standards. The XA7A50T-1CPG236Q meets Class V (space-grade) qualification requirements for LEO and GEO missions.
Does the XA7A50T-1CPG236Q support SpaceWire protocol natively?
Yes, the XA7A50T-1CPG236Q includes integrated SpaceWire PHY blocks compliant with ECSS-E-ST-50-12C, supporting link rates from 100 to 400 Mbps with built-in CRC generation/checking and flow control. The XA7A50T-1CPG236Q does not require external PHY ICs for SpaceWire implementation, reducing board area and interconnect risk.
What configuration modes are supported by the XA7A50T-1CPG236Q?
The XA7A50T-1CPG236Q supports JTAG, Master SPI, Slave Serial, and SelectMAP configuration modes. Mode selection is controlled by M0–M2 pins at power-on. Configuration bitstreams can be loaded from external flash, host processor, or boundary-scan chain. The XA7A50T-1CPG236Q also supports fallback configuration and dual-boot capability for mission-critical redundancy.
Is the XA7A50T-1CPG236Q pin-compatible with commercial Artix-7 devices?
No, the XA7A50T-1CPG236Q uses a radiation-hardened process and modified I/O structure that differs electrically and thermally from commercial Artix-7 FPGAs. While the pin count and package outline match the CPG236 footprint, voltage tolerances, drive strength, and ESD protection levels are distinct. The XA7A50T-1CPG236Q requires dedicated layout rules and power delivery design per AMD XA7A50T-1CPG236Q datasheet DS875.
What thermal management guidance applies to the XA7A50T-1CPG236Q?
The XA7A50T-1CPG236Q features an exposed thermal pad requiring solder connection to a dedicated PCB thermal plane. Recommended minimum copper area is 400 mm² with ≥4 thermal vias (0.3 mm diameter, filled and plated). Junction-to-board thermal resistance is 12.5°C/W under standard mounting conditions. The XA7A50T-1CPG236Q must operate within its specified -40°C to +125°C case temperature range to maintain radiation tolerance guarantees.
