Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based industrial control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XQ7K325T-2RF676M | Higher logic density (325K cells), larger 676-pin RF package, military temp range (-55°C to +125°C) | Targeted at radar processing and high-channel-count test equipment where scalability exceeds XA7A35T-2CSG324I capacity | Choose when >100k logic cells or extreme temperature margin is required; not drop-in compatible due to package and pinout differences |
| XA7Z020-2CLG400I | ARM Cortex-A9 dual-core + programmable logic, 28 nm SoC, 20K logic cells, 400-pin CLG package | Optimized for Linux-capable embedded vision systems needing OS-level software stack alongside hardware acceleration | Prefer when application requires embedded processor + FPGA integration; different architecture limits direct replacement |
Compared with XA7A35T-2CSG324I, the XQ7K325T offers higher density but requires PCB redesign, while the XA7Z020 provides heterogeneous compute but trades logic capacity for CPU integration-neither is pin-compatible, and selection depends on whether scalability or embedded processing is the primary system requirement.
