In-circuit debugger improves interface options for MCU devices

The debugging process remains an important area where many embedded design engineers would like to see improvements. To address these needs and enhance the development experience, Microchip Technology Inc. introduces the MPLAB PICkit 4 In-Circuit Debugger. The low-cost PICkit 4 in-circuit programming and debugging development tool is meant to replace the popular PICkit 3 programmer by offering five times faster programming, a wider voltage range (1.2-5V), improved USB connectivity and more debugging interface options. In addition to supporting Microchip’s PIC^® microcontrollers (MCUs) and dsPIC^® Digital Signal Controllers (DSCs), the tool also supports debugging and programming for the CEC1702 family of hardware cryptography-enabled devices.

This low-cost programming and debugging solution is ideal for those designing in the 8-bit space, but it is also perfectly suited for 16- and 32-bit development due, in part, to its 300 MHz, high-performance ATSAME70Q21B microcontroller on board. The benefits of faster programming time are less waiting and better productivity during development. This is especially important when designing with 32-bit microcontrollers with larger memory capacities.

The PICkit 4 development tool enables debugging and programing using the graphical user interface of MPLAB X Integrated Development Environment (IDE). The tool connects to the design engineer’s computer using a hi-speed USB 2.0 interface and can be connected to the target via an 8-pin single inline header that supports advanced interfaces such as 4-wire JTAG and serial wire debug with streaming data gateway. It is also backward compatible for demo boards, headers and target systems using 2-wire JTAG and In-Circuit Serial Programming™ (ICSP) compatibility.

The new interfaces make this low-cost tool compatible with Microchip’s CEC1702 hardware cryptography-enabled devices. This low-power, but powerful, 32-bit MCU offers easy-to-use encryption, authentication and private and public key capabilities. CEC1702 users can now benefit from using Microchip’s development tools and support rather than being required to invest in third-party tools for programming and debugging.
