MPLAB ® ICD 3 In-Circuit Debugger User’s Guide10.4 USB PORT/POWERThe MPLAB ICD 3 in-circuit debugger is connected to the host PC via a UniversalSerial Bus (USB) port, version 2.0 compliant. The USB connector is located on the sideof the pod.The system is capable of reloading the firmware via the USB interface.System power is derived from the USB interface. The debugger is classified as a highpower system per the USB specification, and requires 300 mA of power from the USBto function in all operational modes (debugger/programmer).Note:The MPLAB ICD 3 in-circuit debugger is powered through its USB connection.The target board is powered from its own supply. Alternatively, theMPLAB ICD 3 can power it only if the target consumes less than 100 mA.Cable Length – The PC-to-debugger cable length for proper operation is shipped inthe debugger kit.Powered Hubs – If you are going to use a USB hub, make sure it is self-powered. Also,USB ports on PC keyboards do not have enough power for the debugger to operate.PC Hibernate/Power-Down Modes – Disable the hibernate or other power savermodes on your PC to ensure proper USB communications with the debugger.10.5 MPLAB ICD 3 DEBUGGERThe debugger consists of a main board enclosed in the casing with a USB connectorand an RJ-11 connector. On the debugger enclosure are indicator lights (LEDs).10.5.1 Main BoardThis component has the interface processor (dsPIC DSC), the USB 2.0 interfacecapable of USB speeds of 480 Mb/sec, a Field Programmable Gate Array (FPGA) forgeneral system control and increased communication throughput, an SRAM for holdingthe program code image for programming into the emulation device on-board Flashand LED indicators.10.5.2 Indicator Lights (LEDs)The indicator lights have the following significance.LED Color DescriptionActive Blue Lit when power is first applied or when target is connected.Status Green Lit when the debugger is operating normally – standby.Red Lit when an operation has failed.Orange Lit when the debugger is busy.DS51766A-page 80© 2008 Microchip Technology Inc.
Hardware Specification10.6 STANDARD COMMUNICATION HARDWAREFor standard debugger communication with a target (Section 2.4 “Debugger ToTarget Communication”, “Standard ICSP Device Communication“), use the RJ-11connector.To use this type of communication with a header board, you may need a device-specificProcessor Pak, which includes an 8-pin connector header board containing the desiredICE/ICD device and a standard adapter board.Note:Older header boards used a 6-pin (RJ-11) connector instead of an 8-pinconnector, so these headers may be connected directly to the debugger.For more on available header boards, see the “Header Board Specification”(DS51292).10.6.1 Standard CommunicationThe standard communication is the main interface to the target processor. It containsthe connections to the high voltage (VPP), VDD sense lines, and clock and dataconnections required for programming and connecting with the target devices.The VPP high-voltage lines can produce a variable voltage that can swing from 0 to 14volts to satisfy the voltage requirements for the specific emulation processor.The VDD sense connection draws very little current from the target processor. Theactual power comes from the MPLAB ICD 3 in-circuit debugger system as the VDDsense line is used as a reference only to track the target voltage. The VDD connectionis 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 isapplied to the MPLAB ICD 3 in-circuit debugger system)• Clock and data signals are protected from high voltages caused by faulty targetssystems, or improper connections• Clock and data signals are protected from high current caused from electricalshorts in faulty target systemsFIGURE 10-1:6-PIN STANDARD PINOUTStandard Socket123456Bottom ofTarget BoardPin Name Function1 VPP Power2 VDD_TGT Power on target3 GND Ground4 PGD (ICSPDAT) Standard Com Data5 PGC (ICSPCLK) Standard Com Clock6 LVP Low Voltage Programming© 2008 Microchip Technology Inc.
