Product details
Overview
XA7A15T-1CSG325Q from AMD is a radiation-tolerant Artix-7 FPGA with 14,892 logic cells, 6.6 Mb of total on-chip 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 applications including satellite command & data handling and payload interface control.
For engineers reviewing the XA7A15T-1CSG325Q datasheet, pinout, applications, or equivalent options, key selection criteria include single-event latch-up (SEL) immunity, TID tolerance up to 100 krad(Si), and QML-Q qualification per MIL-PRF-38535 Class V.
Technical Context
The XA7A15T-1CSG325Q implements a 28 nm bulk CMOS process with hardened configuration memory and triple-modular redundancy (TMR) in CLBs and routing. It includes 120 DSP48E1 slices for arithmetic-intensive signal processing and supports SelectIO standards including LVCMOS, SSTL, and HSTL.
Configuration is performed via JTAG or master SPI mode using external PROM; bitstream encryption and HMAC authentication are supported. The device integrates two 12-bit, 1 MSPS ADCs for system monitoring and supports partial reconfiguration for in-orbit updates.

FAQ
What radiation hardness specifications apply to the XA7A15T-1CSG325Q?
The XA7A15T-1CSG325Q is qualified to 100 krad(Si) total ionizing dose (TID) and exhibits single-event latch-up (SEL) immunity ≥43 MeV·cm²/mg. It also meets single-event upset (SEU) mitigation requirements through hardened configuration memory and supports EDAC for block RAM. These ratings are verified per MIL-STD-883 TM1019 and TM1020 test methods.
Does the XA7A15T-1CSG325Q support partial reconfiguration?
Yes, the XA7A15T-1CSG325Q supports partial reconfiguration via ICAP (Internal Configuration Access Port), enabling dynamic module swapping without resetting the entire device. This capability is used in orbit for updating communication protocols or payload processing algorithms while maintaining housekeeping functions. Configuration security features remain active during partial reconfig cycles.
What is the role of the dual integrated ADCs in the XA7A15T-1CSG325Q?
The XA7A15T-1CSG325Q includes two independent 12-bit, 1 MSPS analog-to-digital converters used for monitoring internal supply voltages (VCCINT, VCCAUX) and die temperature. They eliminate the need for external monitoring ICs in space-qualified power management circuits and provide calibrated data accessible via AXI interface for health telemetry generation.
Is the XA7A15T-1CSG325Q pin-compatible with commercial Artix-7 devices?
No, the XA7A15T-1CSG325Q uses a QML-Q qualified package with different thermal and mechanical specifications than commercial Artix-7 parts. While logic resources and I/O standards align functionally, the CSG325 package has unique solder mask, plating, and screening requirements. Board-level compatibility requires verification against the official XA7A15T-1CSG325Q mechanical drawing and qualification report.
What configuration modes does the XA7A15T-1CSG325Q support?
The XA7A15T-1CSG325Q supports JTAG, master SPI, and slave serial configuration modes. Mode selection is controlled by M0–M2 pins at power-up. Bitstream encryption and HMAC authentication are enforced in all modes, and configuration fallback is supported via dual-BITSTREAM mode with CRC checking on both images.
