Frequently Asked Questions
General Questions
Q: What is the difference between Q-grade and I-grade versions? A: Q-grade devices operate from -40°C to +105°C ambient (125°C junction), while I-grade operates from -40°C to +85°C ambient (100°C junction). Q-grade is for extended automotive temperature applications.
Q: Can I use 5V signals directly with this device? A: Yes, all I/O pins are 5V-tolerant on their inputs, allowing direct interfacing with 5V logic without external level shifters.
Q: What programming cable is required? A: Any Xilinx-compatible JTAG programmer works, including Platform Cable USB II or third-party JTAG adapters supporting Xilinx devices.
Q: Is the configuration volatile or non-volatile? A: Non-volatile. The XA9572XL uses Flash technology, so configuration is retained through power cycles without external memory.
Design and Development
Q: Which design software should I use? A: For new designs, ISE Design Suite is recommended. The device is not supported in Vivado, as it’s designed for legacy CPLD families.
Q: How many I/O pins are available? A: The 64-pin package provides up to 57 user I/O pins, depending on your specific configuration and use of special function pins.
Q: Can I perform in-system updates? A: Yes, through the JTAG interface. The device supports in-system programming without requiring removal from the circuit board.
