3.3.1 Target Connection Pinout

The programming connector pin functions are different for various devices and interfaces. Refer to the following pinout tables for debug and data stream interfaces.

Note: Refer to the data sheet for the device you are using as well as the application notes for the specific interface for additional information and diagrams.

Table 3-1. Pinouts for Debug Interfaces
MPLAB PICkit 5 Connector		DEBUG INTERFACE									Target⁵ Connector
8-Pin SIL¹		ICSP™ (MCHP)	MIPS EJTAG	Cortex® SWD	AVR® JTAG	AVR dW³	AVR UPDI	AVR PDI	AVR ISP	AVR TPI	8-Pin SIL	6-Pin SIL
Pin #	Pin Name	ICSP™ (MCHP)	MIPS EJTAG	Cortex® SWD	AVR® JTAG	AVR dW³	AVR UPDI	AVR PDI	AVR ISP	AVR TPI	Pin #	Pin #
1	TVPP	MCLR/VPP	MCLR	RESET			RESET⁴				1	1
2	TVDD	VDD	VDD/VDDIO	VDD	VTG	VTG	VTG	VTG	VTG	VTG	2	2
3	GND	GND	GND	GND	GND	GND	GND	GND	GND	GND	3	3
4	PGD	DAT	TDO	SWO²	TDO		DAT⁴	DAT	MISO	DAT	4	4
5	PGC	CLK	TCK	SWCLK	TCK				SCK	CLK	5	5
6	TAUX				RESET	RESET/dW		CLK	RESET	RESET	6	6
7	TTDI		TDI		TDI				MOSI		7
8	TTMS		TMS	SWDIO²	TMS						8
Use of a 6-pin header will result in the loss of functions on Pins 7 and 8 affecting EJTAG, JTAG, SWD and ISP. SWO is used for trace. SWDIO is used for debug. dW = debugWIRE Pin may be used for High-Voltage Pulse reactivation of UPDI function depending on device. See device data sheet for details. These are example target connectors that are assumed similar to the debugger unit (SIL).

Table 3-2. Pinouts for Data Stream Interfaces
MPLAB® PICkit™ 5 Connector	DATA STREAM		Target³ Connector
8-Pin SIL¹	PIC and AVR Devices	SAM Devices²	8-Pin SIL
Pin #	DGI UART / CDC	DGI UART / CDC	Pin #
1			1
2	VTG	VTG	2
3	GND	GND	3
4		TX (target)	4
5			5
6			6
7	TX (target)	RX (target)	7
8	RX (target)		8
Use of an 8-pin connector is required for data streaming. A 6-pin connector will result in the loss of functions on Pins 7 and 8. RX and TX pins need to move to accommodate wiring for other devices. This is an example target connector that is assumed similar to the debugger unit (SIL).
