The standard driver board (AC244001), included with the emulator but can be purchased separately, is the main interface to the target processor. It contains the connections to the high voltage (Vpp), Vdd sense lines, and clock and data connections required for programming and connecting with the target devices.
The Vpp high-voltage lines can produce a variable voltage that can swing from 14 to 0 volts to satisfy the voltage requirements for the specific emulation processor.
The Vdd sense connection draws very little current from the target processor. The actual power comes from the MPLAB® REAL ICE™ In-circuit emulation system as the Vdd sense line is used as a reference only to track the target voltage. The Vdd connection is isolated with an optical switch.
The clock and data connections are interfaces with the following characteristics:
- Clock and data signals are in High-Impedance mode (even when no power is applied to the MPLAB REAL ICE In-circuit emulator system)
- Clock and data signals are protected from high voltages caused by faulty targets systems, or improper connections
- Clock and data signals are protected from high current caused from electrical shorts in faulty target systems
Note: When using the standard driver board, the rate for real-time streaming data and tracing is limited to 15 MIPS.
