AMD XA7A25T-1CSG325Q

Overview

XA7A25T-1CSG325Q from AMD is a radiation-tolerant Artix-7 FPGA featuring 25K logic cells, 1.2 Gbps transceivers, and operation up to 100°C junction temperature. It integrates dual 12-bit 1 MSPS ADCs and supports JESD204B interface for high-speed data acquisition in space-grade signal processing systems.

For engineers reviewing the XA7A25T-1CSG325Q datasheet, pinout, applications, or equivalent options, key selection criteria include radiation tolerance (up to 100 krad(Si)), SEU mitigation architecture, transceiver compliance with JESD204B subclass 1, and qualification per QML-Q/V standards.

Technical Context

The XA7A25T-1CSG325Q implements triple modular redundancy (TMR) in CLBs and configuration memory scrubbing to meet single-event upset (SEU) requirements for LEO/MEO missions. Its transceivers support programmable equalization and adaptive clock data recovery for deterministic latency links.

Configurable I/O banks operate from 1.2 V to 3.3 V with SSTL, LVCMOS, and HSTL standards. The integrated ADCs provide simultaneous sampling across two channels with ±1 LSB INL and 69.5 dB SNR at 1 MSPS.

FAQ

What radiation hardness level does the XA7A25T-1CSG325Q support?

The XA7A25T-1CSG325Q is qualified to 100 krad(Si) total ionizing dose (TID) and features SEU mitigation via triple modular redundancy and configuration scrubbing. It meets QML-Q/V requirements per MIL-PRF-38535, making it suitable for low-earth orbit missions where cumulative radiation exposure must remain within strict limits. This radiation tolerance is verified through accelerated testing across full temperature and voltage ranges.

Does the XA7A25T-1CSG325Q include built-in analog-to-digital converters?

Yes, the XA7A25T-1CSG325Q integrates two independent 12-bit, 1 MSPS ADCs with simultaneous sampling capability. These ADCs support direct connection to analog sensors such as thermistors, current shunts, and voltage monitors without external components. Each channel achieves ±1 LSB INL and 69.5 dB SNR, enabling high-fidelity telemetry acquisition in radiation environments where external ADCs may degrade.

What JESD204B capabilities does the XA7A25T-1CSG325Q provide?

The XA7A25T-1CSG325Q supports JESD204B subclass 1 with deterministic latency and multi-device synchronization. Its transceivers operate up to 1.2 Gbps and include adaptive clock data recovery and programmable equalization. This allows seamless interface with radiation-tolerant ADCs like the AD9643-EP, ensuring phase-aligned sampling across radar or comm payload channels without external timing compensation circuitry.

Is the XA7A25T-1CSG325Q pin-compatible with other Artix-7 radiation-tolerant FPGAs?

The XA7A25T-1CSG325Q uses a 325-pin CSG package with defined ball map per AMD documentation. It shares the same footprint and thermal pad layout with XA7A35T-1CSG325Q, enabling mechanical compatibility. However, I/O bank assignments and transceiver placement differ between densities, so PCB redesign is required for logic migration - it is not a drop-in replacement despite identical package code.

What qualification standard applies to the XA7A25T-1CSG325Q?

The XA7A25T-1CSG325Q is qualified per QML-Q and QML-V per MIL-PRF-38535, including lot acceptance testing, burn-in, and radiation characterization. This certification covers manufacturing traceability, reliability stress testing, and failure analysis protocols required for DoD and NASA flight programs. Full qualification reports are available under NDA through AMD's Aerospace & Defense support channel.
