Description
The National Instruments USB-7845 Multifunction Reconfigurable I/O Device, with part numbers 783200-02 and 783200-01, incorporates SRAM memory for storing configuration bits that define the functionality and interconnections of its logic blocks. Upon power-on, the device’s DIO channels default to an input low state with pull-down resistors, however, users have the option to configure a custom power-on state using a user-configured VI.
This versatile device features a characteristic impedance of 50 Ω on Connector 0, ensuring signal integrity, especially when interfaced with external hardware of similar impedance. It supports various reconfiguration types, including total reconfiguration at power-on, total time reconfiguration, and static reconfiguration. Updates to the FPGA are achieved by loading a completely new configuration, which allows the device to adapt to different applications that benefit from the fusion of hardware and software capabilities.
Furthermore, the NI USB-7845 is designed to accommodate future updates, enabling the functionality to evolve in response to protocol updates or to rectify specific bugs, assuring longevity and adaptability in a wide range of applications.
