With five times faster programming and a wider 1.2V to 5V range, the Microchip MPLAB® PICkit™ 4 Development Tool supports low-cost development of even more Microchip controllers. PICkit™ 4 also introduces improved USB connectivity with a hi-speed USB 2.0 interface and advanced debugging over 4-wire JTAG and serial wire debug with streaming data gateway in addition to legacy interfaces. The new advanced interfaces support in-circuit programming and debugging of Microchip’s CEC1702 hardware cryptography-enabled MCUs, in addition to dsPIC® Digital Signal Controllers and PIC® microcontrollers from 8- to 32-bit
