FAQ

What is the maximum operating junction temperature for XC6SLX75-L1CSG484C?

The XC6SLX75-L1CSG484C is rated for a maximum junction temperature of 100°C under continuous operation. This rating applies when operated at the -1 speed grade with 1.2 V core supply and ambient conditions up to 75°C. Thermal design must ensure adequate PCB copper area and airflow to maintain junction temperature below this limit during worst-case logic utilization.

Does XC6SLX75-L1CSG484C support JTAG boundary-scan testing?

Yes, XC6SLX75-L1CSG484C fully supports IEEE 1149.1 JTAG boundary-scan testing through dedicated TCK, TMS, TDI, and TDO pins. The device implements a 4-bit instruction register and supports SAMPLE/PRELOAD, EXTEST, and BYPASS instructions. JTAG is used for both configuration and post-configuration verification of I/O pin states.

Can XC6SLX75-L1CSG484C interface directly with DDR3 SDRAM?

Yes, XC6SLX75-L1CSG484C supports DDR3 SDRAM interfaces up to 800 Mbps using its embedded memory controller hard IP. It requires proper layout of DQ/DQS groups, on-die termination configuration, and precise timing constraints. The controller handles read/write leveling, ZQ calibration, and refresh command generation without external logic.

Is XC6SLX75-L1CSG484C RoHS compliant and lead-free?

Yes, XC6SLX75-L1CSG484C is RoHS compliant and manufactured with lead-free (Pb-free) packaging. The CSG484 package uses matte tin finish on all solder balls and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements. Full compliance documentation is available in AMD's official product change notices.

What configuration modes does XC6SLX75-L1CSG484C support?

XC6SLX75-L1CSG484C supports three primary configuration modes: Master SPI (internal oscillator drives serial flash), Slave Serial (external controller clocks data in), and JTAG (boundary-scan or programming via USB cable). Mode selection is controlled by mode pins M[2:0] at power-up, and all modes support fallback and multi-bitstream selection via boot address pins.
