The XEM7010 is a compact, mezzanine-style FPGA integration module featuring the Xilinx Artix-7 FPGA and High Speed USB 2.0 connectivity via a USB 2.0 Type B connector.
Designed as a full-featured integration system, the XEM7010 provides access to over 120 I/O pins on its 484-pin Artix-7 device and has 512-MiByte DDR3 SDRAM available to the FPGA. Two SPI Flash devices provide a total of 32 MiB of non-volatile memory, one attached to the USB microcontroller and one attached to the FPGA.
Available with A50T and A200T FPGA densities, the XEM7010 is designed for high-performance system integrations.

High Speed USB 2.0 Interface
The XEM7010 uses a Cypress FX2 USB microcontroller to make the XEM a USB 2.0 peripheral. As a USB peripheral, the XEM is instantly recognized as a plug and play peripheral on millions of PCs. More importantly, FPGA downloads to the XEM happen quickly, virtual instruments under FrontPanel update quickly, and data transfers are blazingly fast.
The XEM7010 is designed to compactly support a large number of applications with a small number of on-board peripherals. These peripherals are listed below.
Low-Jitter Crystal Oscillator
A fixed-frequency, 200 MHz, low-jitter oscillator is included on-board and outputs LVDS to the FPGA. The Artix-7 FPGA can produce a wide range of clock frequencies using the on-chip DCM and PLL capabilities.
512-MiByte DDR3 Synchronous DRAM
The module also includes 512-MiByte DDR3 SDRAM with a 16-bit wide interface to the FPGA. This SDRAM is attached exclusively to the FPGA and does not share any pins with the expansion connector. The maximum clock rate of the SDRAM is 400 MHz. With the -1 speed grade of the Artix-7, the maximum clock rate is 400 MHz for a supported peak memory bandwidth of 12.8 Gib/s.
The DDR3 SDRAM is a Micron MT41K256M16TW (or compatible).
FPGA Flash – 4 MiB Serial Flash Memory
A 32 Mib serial flash device (Numonyx M25P32-VME6G or equivalent) provides on-board non-volatile storage for the FPGA. This device is attached directly to the FPGA for use in your design.
Eight LEDs are available for general use as indicators.
The XEM7010 is fully supported by Opal Kelly’s FrontPanel Application. FrontPanel augments the limited peripheral support with a host of PC-based virtual instruments such as LEDs, hex displays, pushbuttons, toggle buttons, and so on. Essentially, this makes your PC a reconfigurable I/O board and adds tremendous value to the XEM7010 as an experimentation or prototyping system.
In addition to complete support within FrontPanel, the XEM7010 is also fully supported by the FrontPanel SDK, a powerful C++ class library available to Windows, Mac OS X, and Linux programmers allowing you to easily interface your own software to the XEM.
In addition to the C++ library, wrappers have been written for C#, Java, and Python making the API available under those languages as well. Sample wrappers (unsupported) are also provided for Matlab and LabVIEW.
Complete documentation and several sample programs are installed with FrontPanel.
