Microchip Technology AC164396

Overview

AC164396 from Microchip Technology is a dedicated PM3 socket module designed to interface the MPLAB PM3 Programmer (DV007004) with Microchip PIC32MZ microcontrollers in 176-lead LQFP packages measuring 20 mm × 20 mm and bearing the -2J package code. It enables in-circuit programming and device verification without soldering, supporting production programming and engineering validation workflows.

For engineers reviewing the AC164396 datasheet, AC164396 pinout, AC164396 application, or AC164396 equivalent, this module's mechanical compatibility with PIC32MZ-2J devices, electrical alignment with MPLAB PM3 voltage and timing specifications, and role as a zero-insertion-force (ZIF) programming interface are critical selection criteria.

Technical Context

The AC164396 implements a passive, precision-machined ZIF socket assembly with gold-plated contacts rated for ≥50,000 insertion cycles. It maps all 176 LQFP pins-including VDD, VSS, PGD, PGC, MCLR, and VCAP-to corresponding terminals on the MPLAB PM3's programming header per Microchip's PM3 socket interface specification.

No onboard logic, voltage regulation, or signal conditioning is present; the module functions solely as a mechanical and electrical bridge. Compatibility is strictly limited to PIC32MZ devices in the 176L LQFP (-2J) package variant and requires DV007004 firmware v3.40 or later.

FAQ

What is the AC164396 used for?

The AC164396 is a socket module that enables programming and debugging of PIC32MZ microcontrollers in 176L LQFP (-2J) packages using the MPLAB PM3 Programmer (DV007004). It eliminates the need for soldering during firmware development and production programming, allowing rapid device swapping and verification. The AC164396 ensures precise mechanical alignment and low-resistance contact for reliable programming sessions.

Does the AC164396 support PIC32MZ devices other than -2J package variants?

No. The AC164396 is mechanically dimensioned and pin-aligned exclusively for the 176-lead LQFP package with 20 mm × 20 mm body size and -2J package code. It does not support PIC32MZ devices in QFN, TQFP, or other LQFP variants (e.g., -1J or -3J), even if pin count matches. Always verify compatibility using Microchip's Device Tool Selector before use.

Is the AC164396 compatible with programmers other than the MPLAB PM3 (DV007004)?

No. The AC164396 is designed solely for use with the MPLAB PM3 Programmer (orderable part DV007004). Its physical connector, pin mapping, and signal routing follow Microchip's proprietary PM3 socket interface specification. It is not electrically or mechanically compatible with MPLAB ICD 4, PICkit 4, or third-party programmers.

What is the maximum operating temperature rating for the AC164396?

The AC164396 has no active components and no specified thermal rating beyond its material limits: the housing is rated for continuous operation from –20 °C to +70 °C, consistent with standard FR4-based socket modules used in benchtop programming environments. Thermal derating is not required under normal MPLAB PM3 usage conditions.

Can the AC164396 be used for high-volume automated programming systems?

The AC164396 is intended for manual or semi-automated benchtop programming-not for integration into robotic handlers or inline production programmers. Its ZIF lever mechanism and hand-insertion design lack the repeatability and durability required for fully automated systems. For high-volume applications, Microchip recommends certified third-party gang programmers or custom socket fixtures validated for >100,000 cycles.
