High-Speed/LVDS Communication (Performance Pak)

The emulator system can be configured to use the high-speed/Low-Voltage Differential Signaling (LVDS) connection for communicating debug and programming instructions to the target. Compared to standard communication, this form of communication provides the following features.

  • Noise cancellation from the low-voltage differential signal (LVDS) technology, which allows:
    • Communication speeds greater than 15 MIPS for data capture, runtime watches, and native trace
    • Longer distances between the emulator and the target
    • Operation in noisy environments
  • Two additional pins used for Serial Peripheral Interface (SPI) trace

The Performance Pak (AC244002) is necessary for high-speed/LVDS communications. For connection information, see the "Performance Pak for the MPLAB REAL ICE™ In-Circuit Emulator User’s Guide" (DS50002528).
