In-Circuit Debugger Taunts Speed Limits

Microchip Technology’s MPLAB ICD 4 in-circuit programming and debugging development tool for PIC microcontrollers (MCUs) and dsPIC digital signal controllers (DSCs) includes all the features found in the MPLAB ICD 3 tool while adding increased speed through a faster processor and increased RAM. The speed improvement is accomplished through a 32-bit MCU running at 300 MHz. The faster processing, along with an increased buffer memory of 2 MB, results in twice the speed as its predecessor.


The puck-shaped tool comes in a durable, black case with a brushed aluminum top with an LED light strip to indicate debugging status. The tool features:
