1.3 MPLAB ICD 4 IN-CIRCUIT DEBUGGER ADVANTAGES
The MPLAB ICD 4 In-Circuit Debugger system provides the following advantages:
Features/Capabilities:
• Connects to computer via high-speed USB 2.0 (480 Mbits/s) cable
• Comes with a standard Microchip debugging connector (RJ-11) and has the
option to use JTAG
• Programs devices using MPLAB X IDE or MPLAB IPE
• Supports multiple breakpoints, stopwatch, and source code file debugging
• Debugs your application on your own hardware in real time
• Sets breakpoints based on internal events
• Monitors internal file registers
• Debugs at full speed
• Configures pin drivers
• Field-upgradeable through an MPLAB X IDE firmware download
• Adds new device support and features by installing the latest version of MPLAB X
IDE (available as a free download at www.microchip.com/mplabx)
• Controls brightness of LEDs
• Includes a test module that can test all communications
Performance/Speed:
• More and faster memory
• A Real-Time Operating System (RTOS)
• No firmware download delays incurred when switching devices
• A 32-bit MCU running at 300 MHz
• A buffer memory of 2 MB
Safety:
• Receive feedback from debugger when external power supply is needed for target
• Supports target supply voltages from 1.2V to 5.5V
• Safely power up to 1A with an optional power supply
• Protection circuitries are added to the probe drivers to guard from power surges
from the target
•V
DD and VPP voltage monitors protect against overvoltage conditions/all lines
have over-current protection
• Programming/debugging pins are physically isolated via relays until voltage is
determined to be safe for connection, programmable resistor value, and direction
(pull-up, pull-down, or nonexistent).
• Controlled programming speed provides flexibility to overcome target board
design issues
• CE and RoHS compliant – conforms to industry standards
