FAQ

What radiation hardness level does the XA7A35T-1CPG236Q meet?

The XA7A35T-1CPG236Q is qualified to 100 krad(Si) total ionizing dose (TID) and features single-event upset (SEU) mitigation via configurable configuration scrubbing. It is fully tested and certified per QML-Q requirements under MIL-PRF-38535, making it suitable for low-earth orbit and geosynchronous missions where cumulative radiation exposure must be managed without functional interruption. The XA7A35T-1CPG236Q includes hardened configuration memory and built-in scrubbing logic that operates autonomously during runtime.

Does the XA7A35T-1CPG236Q support DDR3 memory interfaces?

Yes, the XA7A35T-1CPG236Q supports DDR3 SDRAM interfaces up to 800 MHz data rate with dedicated memory controller logic and I/O banks compliant with SSTL15 standards. This capability enables direct connection to space-qualified DDR3 components for high-bandwidth data buffering in telemetry and imaging applications. The XA7A35T-1CPG236Q includes calibration circuitry for DQS-to-clock alignment and supports both fly-by and point-to-point topologies.

What is the operating temperature range for the XA7A35T-1CPG236Q?

The XA7A35T-1CPG236Q is rated for operation from -40°C to +125°C ambient temperature and is qualified across this full range per MIL-STD-883 test conditions. Its thermal design and package construction support sustained operation in spacecraft thermal environments without derating. The XA7A35T-1CPG236Q undergoes burn-in and temperature cycling validation as part of QML-Q certification, ensuring reliability under extreme thermal gradients encountered in orbit.

How many I/O pins does the XA7A35T-1CPG236Q provide?

The XA7A35T-1CPG236Q provides 120 user-configurable I/O pins distributed across multiple banks, each supporting independent voltage settings (1.2 V to 3.3 V) and SelectIO™ standards including LVCMOS, LVDS, and SSTL. These I/Os are electrically isolated per bank and support programmable slew rate and drive strength. The XA7A35T-1CPG236Q uses a 236-pin CP package with 0.5 mm pitch, and all 120 I/Os are accessible on the perimeter for routing flexibility in compact space-grade PCB layouts.

Is the XA7A35T-1CPG236Q pin-compatible with other Artix-7 QML-Q devices?

The XA7A35T-1CPG236Q shares the same 236-pin CP package footprint and I/O pinout with the XA7A50T-1CPG236Q, enabling direct PCB reuse when upgrading logic capacity. However, it is not pin-compatible with devices in different packages (e.g., CSG325 or FBG484) or non-QML variants. The XA7A35T-1CPG236Q maintains consistent power, configuration, and clock pin locations across its package family, simplifying board-level design migration within the same footprint.
