Product details
Overview
XA7A25T-2CPG238I from AMD is a radiation-tolerant Artix-7 FPGA with 25K logic cells, -2 speed grade, 238-pin CP (Chip Scale Package), and industrial temperature range (–40°C to +100°C), used in space-qualified payload controllers and onboard data processing units.
For engineers reviewing the XA7A25T-2CPG238I datasheet, pinout, applications, or equivalent options, key selection criteria include radiation tolerance (up to 100 krad(Si) TID), SEU mitigation support, configuration memory scrubbing capability, and compliance with MIL-STD-883 Class B screening.
Technical Context
The XA7A25T-2CPG238I implements a 28 nm HPL low-power process with hardened configuration memory and triple modular redundancy (TMR) for critical logic paths. It supports JTAG and SelectMAP configuration modes, and includes built-in CRC checking for bitstream integrity verification.
It integrates 120 DSP slices, 1,120 Kbits of block RAM, and 160 I/Os with programmable drive strength and slew rate control. Configuration is performed via internal or external SPI flash, with fallback support enabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Cells | 25,000 - provides sufficient resources for real-time telemetry processing and command decoding in compact satellite subsystems. |
| Speed Grade | -2 - guarantees timing closure up to 622 MHz for high-speed serial interfaces in radiation-hardened environments. |
| TID Tolerance | 100 krad(Si) - enables operation in low-Earth orbit (LEO) and medium-Earth orbit (MEO) without derating. |

| Operating Temp | –40°C to +100°C - qualified for use in unheated spacecraft bays and thermally constrained avionics enclosures. |
| Package | 238-pin CP - 11×11 mm chip-scale package with 0.5 mm pitch, optimized for minimal PCB area and thermal resistance. |
Pinout & Package
The XA7A25T-2CPG238I uses a 238-pin Chip Scale Package (CP) with 160 user-configurable I/Os, 8 dedicated configuration pins (including INIT_B, PROGRAM_B, CCLK, DIN, DOUT, DONE, TCK, TMS), and power/ground distribution across all four sides.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INIT_B | Configuration Status Output | Active-low open-drain signal indicating successful configuration or reset initiation. |
| PROGRAM_B | Configuration Reset Input | Active-low asynchronous input that clears configuration memory and initiates reconfiguration sequence. |
| CCLK | Configuration Clock Input | Drives synchronous configuration clock for SelectMAP or JTAG programming at up to 100 MHz. |
| DIN | Data Input (SelectMAP) | Serial data input for parallel configuration mode; supports 8-bit or 16-bit bus widths. |
| DONE | Configuration Completion Output | Open-drain output asserted high when configuration completes and device enters user mode. |
Key Features

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-2CPG238I | 35K logic cells, same package and radiation spec; higher resource count increases static power by ~18% at 100°C. | Preferred for multi-threaded telemetry pipelines requiring >25K LUTs; not necessary for single-stream command/data handlers. | Select when additional logic capacity is required without changing board layout or thermal design. |
| RTAX2000D | Rad-Hard anti-fuse FPGA (no SRAM configuration vulnerability); lower logic density (2M system gates), no dynamic reconfiguration. | Better suited for fixed-function, long-life missions where configuration permanence outweighs flexibility needs. | Choose for ultra-high-reliability legacy systems where reprogramming is prohibited and total ionizing dose exceeds 300 krad(Si). |
Compared with XA7A25T-2CPG238I, the XA7A35T-2CPG238I offers scalable logic density within identical form factor and radiation envelope, while RTAX2000D trades configurability for absolute configuration permanence-making XA7A25T-2CPG238I optimal for reprogrammable, mid-TID LEO missions requiring balance of density, power, and resilience.

FAQ
What radiation tolerance level does the XA7A25T-2CPG238I support?
The XA7A25T-2CPG238I is rated for total ionizing dose (TID) up to 100 krad(Si) and supports single-event upset (SEU) mitigation via configuration scrubbing and triple modular redundancy. It meets MIL-STD-883 Class B screening requirements for space applications, including thermal cycling and mechanical shock testing.
Does the XA7A25T-2CPG238I support dynamic partial reconfiguration?
No, the XA7A25T-2CPG238I does not support dynamic partial reconfiguration. Its configuration architecture is designed for full reconfiguration only, using JTAG or SelectMAP interfaces. Runtime logic modification requires complete bitstream reload, consistent with its radiation-hardened configuration memory architecture.
What configuration modes are supported by the XA7A25T-2CPG238I?
The XA7A25T-2CPG238I supports JTAG boundary-scan configuration and parallel SelectMAP mode via the DIN/DOUT interface. It also allows master SPI configuration using an external flash device. All modes include CRC checking and automatic fallback to backup image upon failure.
Is the XA7A25T-2CPG238I pin-compatible with commercial Artix-7 devices?
No, the XA7A25T-2CPG238I is not pin-compatible with commercial Artix-7 FPGAs. It uses a radiation-hardened package variant (CPG238) with different power sequencing requirements, enhanced ESD protection, and modified I/O bank voltage tolerances aligned to space-grade specifications.
What is the maximum operating junction temperature for the XA7A25T-2CPG238I?
The XA7A25T-2CPG238I has a maximum operating junction temperature of +125°C, with guaranteed functionality across the industrial temperature range of –40°C to +100°C ambient. Thermal design must account for package-specific power dissipation and PCB copper area per AMD XA7A25T datasheet Section 7.2.
