The Technobox 7757 is an advanced FPGA-based module for configurable digital I/O that offers in the XMC form factor many of the features and functions of the long-running Technboox P/Ns 2674 and 4289. The standard assembly is built around an Altera Cyclone FPGA (5CGXFC4C6F27I7N) and features a total of 32 general-purpose RS422/RS485 driven digital I/Os wired to both the front panel and rear PN4 connector. Bi-directionality is controlled by an output from the FPGA. The 32-bit data bus is shared between the ALTERA and the PCI interface devices. SRAM (256K x 32b) is accessible from the Altera part as well as the PCIE interface.The SRAM address is driven by ALTERA outputs, permitting a variety of SRAM architectures.
