XQ1701LSO20M FPGAs Overview

The QPro series XQ1701LSO20M are Xilinx 3.3V high-density configuration PROMs. The XQR1701L are radiation hardened. These devices are manufactured on Xilinx QML certified manufacturing lines utilizing epitaxial substrates and TID lot qualification (per method 1019). When the FPGA is in Master Serial mode, it generates a configuration clock that drives the PROM. A short access time after the rising clock edge, data appears on the PROM DATA output pin that is connected to the FPGA DIN pin. The FPGA generates the appropriate number of clock pulses to complete the configuration. Once configured, it disables the PROM. When the FPGA is in Slave Serial mode, the PROM and the FPGA must both be clocked by an incoming signal.

Multiple devices can be concatenated by using the CEO output to drive the CE input of the following device. The clock inputs and the DATA outputs of all PROMs in this chain are interconnected. All devices are compatible and can be cascaded with other members of the family. For device programming, either the Xilinx Alliance or Foundation series development system compiles the FPGA design file into a standard Hex format, which is then transferred to most commercial PROM programmers.

  • Q: Does the price of XQ1701LSO20M devices fluctuate frequently?
  • The FPGAkey search engine monitors the XQ1701LSO20M inventory quantity and price of global electronic component suppliers in real time, and regularly records historical price data. You can view the historical price trends of electronic components to provide a basis for your purchasing decisions.
  • Q: Do I have to sign up on the website to make an inquiry for XQ1701LSO20M?
  • No, only submit the quantity, email address and other contact information required for the inquiry of XQ1701LSO20M, but you need to sign up for the post comments and resource downloads.
  • Q: How can I obtain software development tools related to the Xilinx FPGA platform?
  • In FPGA/CPLD design tools, Xilinx's Vivado Design Suite is easy to use, it is very user-friendly in synthesis and implementation, and it is easier to use than ISE design tools; The specific choice depends on personal habits and functional requirements to specifically select a more suitable match. You can search and download through the FPGA resource channel.
  • Q: Where can I purchase Xilinx XQ1701L Development Boards, Evaluation Boards, or QPro Series Configuration PROMs Starter Kit? also provide technical information?
  • FPGAkey does not provide development board purchase services for the time being, but customers often consult about ZedBoard, Basys 3 board, TinyFPGA BX, Nexys4-DDR, Terasic DE10-Nano, Digilent Arty S7, etc. If you need relevant technical information, you can submit feedback information, our technicians will contact you soon.
  • Q: How to obtain XQ1701LSO20M technical support documents?
  • Enter the "XQ1701LSO20M" keyword in the search box of the website, or find these through the Download Channel or FPGA Forum .
  • Q: What should I do if I did not receive the technical support for XQ1701LSO20M in time?
  • Depending on the time difference between your location and our location, it may take several hours for us to reply, please be patient, our FPGA technical engineer will help you with the XQ1701LSO20M pinout information, replacement, datasheet in pdf, programming tools, starter kit, etc.
