FAQ

What is the operating temperature range for XA7A100T-2FGG484I?

The XA7A100T-2FGG484I is rated for industrial temperature operation from –40°C to +100°C. This range is validated per AEC-Q100 Grade 2 qualification and supports deployment in engine control units, radar modules, and other automotive-adjacent systems where ambient thermal stress exceeds commercial-grade limits. The XA7A100T-2FGG484I maintains full functionality and timing closure across this range without derating.

Does XA7A100T-2FGG484I support encrypted configuration?

Yes, XA7A100T-2FGG484I supports AES-256 bitstream encryption and SHA-256 HMAC authentication for secure configuration. These features are implemented in hardware and require no external security ICs. The XA7A100T-2FGG484I enforces authenticated boot before releasing DONE, preventing unauthorized or tampered bitstreams from executing in safety-critical applications.

How many transceivers does XA7A100T-2FGG484I include?

The XA7A100T-2FGG484I integrates 16 GTP transceivers, each capable of line rates up to 12.5 Gbps. These transceivers support protocols including PCIe Gen3, SATA, and CPRI. Each transceiver pair shares a common reference clock and can be independently configured for different standards, enabling flexible high-speed serial interface consolidation within a single XA7A100T-2FGG484I device.

What configuration modes are supported by XA7A100T-2FGG484I?

XA7A100T-2FGG484I supports Master SPI, Slave Serial, JTAG, and BPI configuration modes. Mode selection is controlled by M0–M2 pins at power-up. The XA7A100T-2FGG484I also supports fallback configuration and multi-boot using external flash memory, allowing field-upgradable bitstreams without hardware modification.

Is there on-chip analog-to-digital conversion capability in XA7A100T-2FGG484I?

Yes, XA7A100T-2FGG484I includes two integrated 12-bit, 1 MSPS analog-to-digital converters. These ADCs are accessible via dedicated analog input pins and support internal reference voltage or external reference selection. They are intended for system monitoring tasks such as power rail voltage tracking or temperature sensing, reducing reliance on external supervisory ICs in the XA7A100T-2FGG484I-based design.
