ZTEX USB-FPGA Module 2.13

Description

USB-FPGA Module 2.13 is an Artix 7 FPGA Board with USB 2.0 controller, 256 MB DDR3 SDRAM, Flash, many GPIO's and on-board voltage regulators. It's available in 4 variants with different FPGA types: XC7A35T, XC7A50T, XC7A75T and XC7A100T

Features

• Four Xilinx Artix 7 FPGA variants: XC7A35T, XC7A50T, XC7A75T and XC7A100T
• USB 2.0 interface using Cypress CY7C68013A EZ-USB FX2 Microcontroller (100 pin version)
• Four Xilinx Artix 7 FPGA variants: XC7A35T, XC7A50T, XC7A75T and XC7A100T
• External I/O connector (consisting in two female 2x32 pin headers with 2.54mm grid) provides:
  • 100 General Purpose I/O's (GPIO) connected to FPGA
  • JTAG signals
  • Reset signal
  • External power (4.5 V .. 16 V) input
  • 3.3V output
  • I/O voltage output or input
• 256 MByte DDR3 SDRAM:
  • Up to 400 MHz clock frequency
