Microchip Technology AC164358

Overview

AC164358 from Microchip Technology is a dedicated socket module for programming 28-lead QFN microcontrollers with 5 mm × 5 mm body and 0.9 mm thickness in MQ package code, designed exclusively for use with the MPLAB PM3 production programmer (DV007004). It enables high-reliability, repeatable device programming in manufacturing environments for PIC® MCUs.

For engineers reviewing the AC164358 datasheet, AC164358 pinout, AC164358 application, or AC164358 equivalent, key selection factors include QFN-28 (5×5 mm, 0.9 mm height) mechanical compatibility, PM3 interface signaling compliance, thermal stability during repeated insertion cycles, and alignment tolerance for automated handling in production programming stations.

Technical Context

The AC164358 implements a precision-machined zero-insertion-force (ZIF) socket interface optimized for 28-lead QFN packages with 0.5 mm pitch and exposed thermal pad. It routes all 28 signal paths-including VDD, VSS, PGD, PGC, MCLR, and VPP-through gold-plated contacts rated for ≥50,000 mating cycles.

Designed as a plug-in module for the MPLAB PM3 platform, AC164358 provides mechanical registration via keyed mounting slots and includes integrated ESD protection on all programming lines to prevent damage during high-volume device handling.

FAQ

What is the AC164358 used for?

The AC164358 is a socket module that physically interfaces 28-lead QFN microcontrollers to the MPLAB PM3 production programmer (DV007004). It enables repeatable, low-damage programming of PIC® MCUs during manufacturing without soldering or manual wiring. The AC164358 ensures precise alignment and consistent electrical contact for high-throughput firmware loading.

Which microcontroller packages does the AC164358 support?

The AC164358 supports only 28-lead QFN packages with 5 mm × 5 mm body size, 0.9 mm thickness, and MQ package code - as defined by Microchip's device packaging standards. It does not support TQFP, SOIC, or other QFN variants such as 32L, 40L, or different dimensions or thicknesses.

Is the AC164358 compatible with programmers other than the MPLAB PM3?

No. The AC164358 is mechanically and electrically designed exclusively for use with the MPLAB PM3 production programmer (DV007004). Its mounting interface, signal routing, and power delivery are not compatible with MPLAB ICD, PICkit, or third-party programmers.

Does the AC164358 require additional cables or adapters?

No. The AC164358 mounts directly into the designated socket bay of the MPLAB PM3 unit and requires no external cables, adapters, or breakout boards. All connections are made internally through the PM3's standardized module interface when the AC164358 is fully seated and locked.

How is the AC164358 mounted and secured in the PM3 programmer?

The AC164358 features keyed mounting slots and a retention latch that aligns with corresponding guides and locking mechanisms inside the MPLAB PM3 chassis. Once inserted, the module is secured by a spring-loaded lever that applies uniform pressure across the QFN package during programming, ensuring stable contact without over-compression.
