Product Details

Our much anticipated mini-module range (42x61mm size, stackable) starts with our High-Speed USB 2.0 (480Mb/s) FPGA aes220 a and b modules. Based around the Xilinx Spartan3AN FPGA family and the Cypress CY7C68013A FX2LP micro-controller, they are fully autonomous thanks to their on-board crystal oscillator, 128Mb of 100Mhz SDRAM and power supply. Read more below or in the Data Sheet and User Manual.

Aessent Technology also supply a full range of connectors/headers and cables for use with the modules: visit our cables & connectors section here.

The aes220 modules are part of Aessent Technology mini-modules series. The modules includes their own DC/DC converter and crystal oscillator. All they require is a 5Vdc power supply if disconnected from the USB. Both modules are identical save for the FPGA loaded on the board, the aes220a comes with the Xilinx XC3S200AN while the aes220b is fitted with a Xilinx XC3S400AN.

Their tiny size (42x61mm) allows fitting in tight places and thanks to their stackable interface they can easily be combined with other modules. The mini-modules offer a flexible clock implementation with the micro-controller clock connected to the FPGA and 16 GCLK inputs present on the external connectors allowing for multiple clock inputs (for a 10MHz external reference for example, but also for running buses or serial links requiring an external clock). The FPGA possesses four Digital Frequency Synthesiser (DFS) to multiply any clock provided up to 334MHz.

The modules provide 72 GPIO (General Purpose Inputs Outputs) linked directly to the Xilinx device which can be accessed using the two 48 pin 0.1” pitch through hole connectors on either side of the modules. These comprise a mix of single ended and differential pair tracks as well as the GCLK inputs previously mentioned. The Xilinx Spartan 3AN devices offer integrated flash memory for device configuration with enough space for two different configurations or data storage or a mix of both. In addition the SDRAM device provides 128Mb of RAM memory with fast access time (16bits parallel data bus and 100MHz clock). See Xilinx pages for more documentation on the FPGA itself.

The Cypress FX2LP micro-controller provides the communication between the host computer and the FPGA. The RAM and EEPROM of the micro-controller are fully accessible allowing customisation of the communication link. Numerous examples are provided on how to program and use the micro-controller including most typical usages. Both the micro-controller and the FPGA can be configured using a simple USB cable (or also using a JTAG programmer via standard Xilinx JTAG connector in the case of the FPGA). VHDL or Verilog code synthesising for the FPGA is via Xilinx' free ISE WebPACK or ISE Design Suite, both downloadable from the Xilinx website.

There is no need for learning about USB communication protocols as libraries are provided for dealing with the communication between the host PC, the micro-controller and the FPGA. All programs and libraries are free and Open Source so as not to be tied up with any proprietary tools and permitting customisation to the user's requirements. Examples, tools and libraries are all available on both Windows and Linux platforms.
