Microchip Technology AC162069

Overview

AC162069 from Microchip Technology is an interface cable that adapts the MPLAB ICD 2 debugger's RJ-11 output to individual male header pins for direct insertion into standard 0.1-inch pitch solderless breadboards. It supports in-circuit debugging and programming of PIC® and dsPIC® microcontrollers via the ICD 2's ICSP™ interface, with a 6-pin breakout matching the ICD 2 pinout and 6-inch length for benchtop flexibility.

For engineers reviewing the AC162069 datasheet, AC162069 pinout, AC162069 application, or AC162069 equivalent, key considerations include its fixed 6-pin ICSP™ signal mapping, breadboard-compatible 0.1" spacing, compatibility exclusively with MPLAB ICD 2 (not ICD 3 or PICkit™), and mechanical fit for prototyping without soldering or custom adapters.

Technical Context

The AC162069 implements a passive, unidirectional signal routing from the MPLAB ICD 2's 6-position RJ-11 connector to six discrete 0.1"-pitch male pins. It carries VDD, VPP/MCLR, PGD, PGC, VSS, and AUX signals-no level shifting, buffering, or active circuitry is included.

All conductors are individually shielded twisted pairs terminated with molded RJ-11 plug and tinned copper header pins. The cable complies with Microchip's ICSP™ timing and voltage specifications for PIC/dsPIC devices when used with the ICD 2 host unit.

FAQ

What is the AC162069 used for?

The AC162069 is a passive breakout cable that connects the MPLAB ICD 2 debugger to a solderless breadboard using six discrete 0.1"-pitch male pins. It enables direct ICSP™ programming and debugging of PIC® and dsPIC® microcontrollers during early-stage prototyping without soldering or custom PCBs. The AC162069 preserves all original ICD 2 signal integrity and timing compliance.

Is the AC162069 compatible with MPLAB ICD 3 or PICkit™ programmers?

No, the AC162069 is mechanically and electrically designed only for the MPLAB ICD 2's RJ-11 interface. Its pinout, connector keying, and signal assignment match the ICD 2 specification exclusively. Using it with ICD 3 (which uses USB and different pinouts) or PICkit™ (which uses ICSP headers directly) will not function and may risk misconnection. The AC162069 must be used strictly with the MPLAB ICD 2.

Does the AC162069 include level-shifting or signal conditioning?

No, the AC162069 contains no active components, resistors, capacitors, or level-shifting circuitry. It is a direct-wire passive adapter with shielded twisted-pair conductors routed 1:1 from the ICD 2's RJ-11 pins to the corresponding male header pins. Signal levels, timing, and drive strength remain identical to those delivered by the ICD 2 itself. The AC162069 does not modify or condition any ICSP™ signals.

What are the six signals mapped on the AC162069 breakout pins?

The AC162069 maps the standard MPLAB ICD 2 ICSP™ signals: Pin 1 = VDD (target power), Pin 2 = VPP/MCLR (programming voltage/reset), Pin 3 = PGD (data), Pin 4 = PGC (clock), Pin 5 = VSS (ground), and Pin 6 = AUX (unused on most targets). This exact 6-signal mapping matches Microchip's official ICD 2 pinout documentation and ensures correct connection to PIC/dsPIC ICSP™ headers.

Can the AC162069 be used with 3.3 V target microcontrollers?

Yes, but only if the target board provides its own regulated 3.3 V supply and the ICD 2 is configured to use target-supplied VDD (not ICD 2–generated VDD). The AC162069 passes VDD directly from the ICD 2, which defaults to 5 V; applying 5 V to a 3.3 V-only device may damage it. Users must disable ICD 2 VDD output and rely on external 3.3 V power - the AC162069 supports this configuration because it routes all signals passively without modification. Always verify VDD source before connecting the AC162069.
