FAQ

What is the maximum operating frequency of the XC7S50-1CSGA324C?

The XC7S50-1CSGA324C has a -1 speed grade, guaranteeing reliable operation up to 450 MHz for system clocks under worst-case commercial temperature and voltage conditions. This rating applies to synchronous logic paths meeting timing constraints in Vivado implementation tools, not to individual I/O or transceiver rates.

Does the XC7S50-1CSGA324C include built-in analog-to-digital conversion?

Yes, the XC7S50-1CSGA324C integrates two independent 12-bit, 1 MSPS ADCs accessible via dedicated analog input pins. These ADCs support simultaneous sampling and are calibrated across temperature, enabling direct connection to sensors such as thermistors, potentiometers, or current shunts without external converters.

Can the XC7S50-1CSGA324C be used as a PCIe endpoint device?

Yes, the XC7S50-1CSGA324C includes hardened PCIe Gen2 x1 endpoint logic compliant with PCI Express Base Specification v2.1. It supports enumeration, memory-mapped I/O, and MSI interrupts, allowing direct attachment to host CPUs without external bridge ICs or protocol translation layers.

What configuration methods does the XC7S50-1CSGA324C support?

The XC7S50-1CSGA324C supports master SPI, slave serial, JTAG, and BPI configuration modes. Boot sources include quad-SPI flash (most common), parallel NOR flash, or external processors via SelectMAP. Configuration is initiated automatically on power-up based on M0–M2 pin states.

Is bitstream encryption supported on the XC7S50-1CSGA324C?

Yes, the XC7S50-1CSGA324C supports AES-256 bitstream encryption with HMAC authentication. Keys are stored in on-chip eFUSE and protected against readback. This prevents unauthorized cloning or reverse engineering of the programmed logic design during field deployment.

What is the thermal pad requirement for the XC7S50-1CSGA324C CSGA package?

The XC7S50-1CSGA324C uses a 324-ball CSGA package with an exposed thermal pad on the underside. This pad must be soldered to a solid copper thermal plane on the PCB, connected via ≥6 thermal vias (0.3 mm diameter) to internal ground planes to maintain junction temperature below 100°C under full utilization.
