FAQ

What is the maximum supported I/O standard voltage for XC7S25-2CSGA324C?

XC7S25-2CSGA324C supports single-ended I/O standards up to 1.8V (LVCMOS18) and differential standards including SSTL15 and HSTL_I. Each of its 10 I/O banks has independent VCCO, allowing mixed-voltage operation. The device does not support 2.5V or 3.3V I/O standards on any bank.

Does XC7S25-2CSGA324C include on-chip configuration memory?

Yes, XC7S25-2CSGA324C integrates 256 Mb of SPI flash memory for configuration storage. This eliminates the need for an external serial PROM and enables single-chip boot in master SPI mode. The integrated flash supports dual-image storage for fail-safe firmware updates.

What is the thermal pad requirement for XC7S25-2CSGA324C's CSGA package?

XC7S25-2CSGA324C's 324-ball CSGA package includes an exposed thermal pad on the underside. The pad must be soldered to a solid copper thermal plane on the PCB with ≥60% solder coverage. Thermal vias under the pad should be filled or capped to prevent solder wicking during reflow.

Can XC7S25-2CSGA324C perform partial reconfiguration in-system?

Yes, XC7S25-2CSGA324C supports partial reconfiguration using Vivado tools. This allows dynamic replacement of logic modules without resetting the entire device or disrupting active I/O. Implementation requires dedicated ICAP interface access and proper partitioning during RTL synthesis.

What clocking resources are available in XC7S25-2CSGA324C?

XC7S25-2CSGA324C includes two MMCM (Mixed-Mode Clock Manager) blocks, each supporting input frequency ranges from 10–800 MHz and generating up to six output clocks. These provide jitter filtering, phase shifting, and frequency synthesis for interfaces like DDR3, MIPI CSI-2, and PWM generators within the XC7S25-2CSGA324C fabric.
