Up to 32 Site ISP Signal Switching


MPX160A is a signal multiplexer for device in-system programming/testing. It allows the ISP connection coming from the programmer/tester to be switched to one of the available output channels.
In this way, a single programmer/tester can easily handle multiple device programming, whether on a single board or distributed across multiple boards in a panel assembly.


  • Switching of 160 signals;
  • Easy integration with all ATE systems;
  • Multiplexing through FET and Reed relay;
  • Controllable by a host PC or ATE through RS-232 or parallel control lines;
  • Compact size.

Hardware Features

MPX160A features state-of-the-art electronics to provide you with high integration flexibility in a compact footprint—ideal for integration inside a fixture.

  • Single, wide range power supply input;
  • Three working modes (see figures), with up to 32 ISP channels;
  • Depending on the working mode, each of the ISP channel is composed of:
    - Either six or three digital, bidirectional lines;
    - Either two or one analog/digital lines (analog out, digital in/out);
    - Either two or one power lines;
    - One ground line (common for all channels).

Software Features

MPX160A is controlled via either ASCII-based commands (through its RS-232 channel) or via control lines. ASCII commands allow for selecting the output channel or to disconnect all of the output channels.
