FAQ

What is the maximum supported transceiver line rate for XC7A15T-1FTG256I?

The XC7A15T-1FTG256I supports a maximum transceiver line rate of 12.5 Gbps per GTPE2 lane. This capability enables compliance with DisplayPort 1.2, SATA III, and PCIe Gen2 protocols. The XC7A15T-1FTG256I achieves this rate under standard -1 speed grade conditions at junction temperatures up to 100°C and VCCAUX = 1.8 V.

Does XC7A15T-1FTG256I support bitstream encryption?

Yes, XC7A15T-1FTG256I supports AES-256 bitstream encryption with key storage in one-time-programmable eFUSE and HMAC authentication. This feature prevents unauthorized readback or cloning of configuration data. The XC7A15T-1FTG256I implements hardware-accelerated decryption during configuration, adding no measurable delay to startup time.

How many I/O banks does XC7A15T-1FTG256I have, and what voltage ranges do they support?

XC7A15T-1FTG256I has 14 configurable I/O banks. Each bank supports selectable VCCO voltages from 1.2 V to 3.3 V, enabling mixed-signaling interfaces such as LVDS_25 (2.5 V), SSTL15 (1.5 V), and HSTL_I (1.5 V). The XC7A15T-1FTG256I requires separate VCCAUX (1.8 V) and VCCINT (1.2 V) supplies regardless of I/O bank settings.

What configuration modes are supported by XC7A15T-1FTG256I?

XC7A15T-1FTG256I supports master SPI, slave serial, JTAG, and BPI configuration modes. Mode selection is controlled by the M[2:0] pins at power-up. The XC7A15T-1FTG256I also supports fallback configuration and dual-boot capability when using external flash with multiple bitstreams.

Is XC7A15T-1FTG256I qualified for automotive applications?

No, XC7A15T-1FTG256I is not AEC-Q100 qualified and is rated for industrial temperature range (–40°C to +100°C). It lacks automotive-specific reliability testing, enhanced ESD protection, and extended lifetime qualification. For automotive use, AMD offers the XA7A15T variant with full AEC-Q100 Grade 3 certification and extended temperature support up to +125°C junction.
