MPLAB® PICkit™ 4 In-Circuit Debugger/Programmer

Microchip presents the next generation of fast, feature-rich, low-cost debugging and programming

Image of Microchip's MPLAB® PICkit™ 4 Debugger ProgrammerMicrochip's 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 V to 5 V), 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 high-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. The MPLAB PICkit 4 programmer has all the features a design engineer needs for working with PIC, dsPIC, and CEC1702 devices, as well as the capability to support future products for many years to come.
