• 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
https://www.microchip.com/mplabx/
).
• Indicates debugger status via the indicator light strip.
• Operates within a temperature range of 0-70 degrees Celsius.
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.
Safety:
• Receive feedback from debugger when external power supply is needed for target.
• Supports target supply voltages from 1.2 to 2.8V for low voltage program mode entry and 2.8 to 5.0V for low
voltage and high voltage program mode entry.
• Safely power up to 1A with an optional 9V DC power supply.
• Protection circuitries are added to the probe drivers to guard from power surges from the target.
• V
DD
and V
PP
voltage monitors protect against overvoltage conditions/all lines have over-current protection.
• Programming/debugging pins with a programmable range of resistor values, plus 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.
