FAQ

What is the maximum supported I/O standard voltage for XC6SLX16-2FTG256C?

The XC6SLX16-2FTG256C supports I/O voltages from 1.2 V to 3.3 V across its 12 configurable I/O banks. Each bank operates independently, allowing mixed-voltage interfaces such as 1.8 V LVDS receivers alongside 3.3 V LVTTL peripherals within a single XC6SLX16-2FTG256C design.

Does XC6SLX16-2FTG256C support JTAG boundary-scan testing?

Yes, XC6SLX16-2FTG256C fully complies with IEEE 1149.1 (JTAG) and supports boundary-scan testing via dedicated TCK, TMS, TDI, and TDO pins. The device also enables INTEST and EXTEST instructions for interconnect verification and internal logic testing during production and field diagnostics.

Can XC6SLX16-2FTG256C be configured using serial NOR flash memory?

Yes, XC6SLX16-2FTG256C supports Master SPI configuration mode, enabling direct boot from standard 4-wire serial NOR flash devices. The DIN pin receives the bitstream, while CCLK is generated internally, eliminating need for external clock sources during configuration.

What clock management resources are integrated into XC6SLX16-2FTG256C?

XC6SLX16-2FTG256C integrates two Digital Clock Managers (DCMs) per device. Each DCM provides frequency synthesis, phase shifting, duty cycle correction, and jitter reduction - supporting up to eight independent clock outputs with programmable divide/multiply ratios and fine-grained phase adjustment.

Is bitstream encryption supported on XC6SLX16-2FTG256C?

Yes, XC6SLX16-2FTG256C supports AES-256 bitstream encryption. Configuration bitstreams can be encrypted using Xilinx iMPACT or Vivado tools, and decrypted on-chip using keys stored in battery-backed RAM, preventing unauthorized readback or cloning of the programmed logic design.
