Acromag, Inc. Cyclone II FPGA with Digital I/O (JTAG-configured), IP-EP200 Series IP-EP204

Up to 48 TTL or 24 differential RS485 Altera Cyclone II EP2C20 FPGA programmable via JTAG port or via the IP bus directly This series of plug-in mezzanine modules provides a user-customizable Altera® Cyclone II FPGA on an Industry Pack (IP) module. The module allows users to develop and store their own instruction set in the FPGA for adaptive computing applications. Typical uses include specialized communication systems over RS422/485 networks, test fixture simulation of signals over TTL-switched lines, and analysis of acquired data using specialized mathematical formulas such as those developed with MathWorks’s MatLab® software. The FPGA on Acromag’s IP-EP200 modules can control up to 48 TTL or 24 RS485 I/O signals or a mix of both types. Another model interfaces 24 LVDS I/O channels. User application programs are downloaded through the JTAG port or via the IP bus directly into the FPGA. A pre-programmed internal CPLD facilitates initialization by acting as the bus controller during power-up and while the program is downloading. This bus controller is limited to functions necessary for power-up and downloading. After the program downloads, the FPGA takes control of the IP bus and the CPLD disables.
