AMD XA7A50T-1CSG324I

Overview

XA7A50T-1CSG324I from AMD is a radiation-tolerant Artix-7 FPGA featuring 50,400 logic cells, 285 DSP slices, 2.55 Mb of block RAM, and support for LVDS I/O up to 1.0 Gbps. It operates across -40°C to +100°C and is qualified for space-grade applications including satellite command & data handling.

For engineers reviewing the XA7A50T-1CSG324I datasheet, pinout, applications, or equivalent options, key selection factors include radiation tolerance (up to 100 krad(Si) TID), SEU mitigation architecture, extended temperature operation, and QML-V qualification status.

Technical Context

The XA7A50T-1CSG324I implements triple modular redundancy (TMR) in configuration logic and includes built-in scrubbing controllers to detect and correct single-event upsets. Its SelectIO resources support programmable I/O standards including LVCMOS, SSTL, and differential LVDS with adjustable drive strength and slew rate control.

This device uses a 28 nm HKMG process and integrates hardened clock management tiles with MMCM and PLL blocks supporting input frequencies from 10 MHz to 800 MHz and output jitter below 150 ps RMS. Configuration occurs via JTAG or master SPI mode using external flash memory.

FAQ

What radiation tolerance level does the XA7A50T-1CSG324I support?

The XA7A50T-1CSG324I is rated for total ionizing dose (TID) up to 100 krad(Si) and features SEU mitigation through triple modular redundancy and configurable scrubbing. It undergoes full QML-V Class V qualification per MIL-PRF-38535, including proton and gamma irradiation testing. This makes the XA7A50T-1CSG324I suitable for missions in low Earth orbit and medium Earth orbit environments where cumulative radiation exposure must be managed over multi-year lifetimes.

Does the XA7A50T-1CSG324I support JTAG boundary-scan testing?

Yes, the XA7A50T-1CSG324I fully supports IEEE 1149.1 JTAG boundary-scan for in-system verification and test access. Its TAP controller enables instruction register access, device ID reading, and boundary-scan chain configuration. This capability is integral to flight hardware validation workflows and is verified during QML-V qualification. Engineers can perform pre-launch board-level diagnostics using standard JTAG tools with the XA7A50T-1CSG324I.

What configuration modes are supported by the XA7A50T-1CSG324I?

The XA7A50T-1CSG324I supports master SPI, slave serial, slave parallel, and JTAG configuration modes. Mode selection is controlled by M0–M2 pins at power-up. Master SPI is most commonly used for autonomous boot from external flash memory, while JTAG enables debug and reprogramming in-flight. All modes are radiation-tested and supported in the XA7A50T-1CSG324I's configuration architecture.

Is the XA7A50T-1CSG324I pin-compatible with other Artix-7 space-grade FPGAs?

The XA7A50T-1CSG324I shares the same 324-pin CSG package footprint with the XA7A35T-1CSG324I and XA7A75T-1CSG324I, enabling PCB reuse across performance tiers. However, I/O bank assignments and voltage requirements differ between variants, so schematic review and constraint file updates are required. Pin compatibility is mechanical only - not electrical or functional - and the XA7A50T-1CSG324I must be validated independently for each target application.

What development tools are required to program the XA7A50T-1CSG324I?

Vivado Design Suite 2022.2 or later is required to synthesize, implement, and generate bitstreams for the XA7A50T-1CSG324I. AMD provides a dedicated device definition and radiation-aware simulation libraries. Programming is performed via JTAG using compatible debug probes or through master SPI using industry-standard flash programmers. The XA7A50T-1CSG324I does not require proprietary toolchains beyond standard Vivado licensing with aerospace device support enabled.
