The new programmer is low-cost and builds on features of PICkit 3 to offer a five times increase in programming speed, more functionality, a wider target-device voltage range and more debugging interface options.
Targetting 8-, 16- or 32-bit devices, the faster programming time offered by PICkit 4 will most benefit developers using 32-bit MCUs with larger memories. The tool will also support Microchip’s PIC MCUs and DSCs and programming and debugging of the cryptography-enabled CEC1702 family.
The wider voltage range supports voltages from 5.5V down to 1.20V. The tool connects to the chip through an eight-pin single in-line header using two device I/O pins and the reset line to implement in-circuit debugging and In-Circuit Serial Programming. The PICkit 4 also supports advanced interfaces such as four-wire JTAG and serial wire debug with streaming data gateway; and is also backward compatible for demo boards, headers and target systems using two-wire JTAG and ICSP compatibility.
The PICkit 4 has a ‘programmer-to-go’ function with the addition of a micro-SD card slot to hold project code and the ability to be powered by the target board enabling in-the-field programming. Other features include: automatic programming, as fast as allowed by the device; supply of up to 50mA of power to the target; and minimal current consumption at less than 100µA.
