Microchip Technology AC164349

Overview

AC164349 from Microchip Technology is a production-grade socket module designed for programming 80-lead TQFP (12×12 mm) PIC18F8xJ72 microcontrollers using the MPLAB PM3 programmer (DV007004). It supports PIC18F86J72-PT and PIC18F87J72-PT devices, features gold-plated contacts, operates at ambient temperatures up to +70°C, and is rated for ≥50,000 insertion cycles.

For engineers reviewing the AC164349 datasheet, AC164349 pinout, AC164349 application, or AC164349 equivalent, key selection criteria include TQFP-80L mechanical compatibility, PM3 interface signaling compliance, thermal cycling endurance, and verified support for PIC18F86J72/87J72 device families in high-volume programming workflows.

Technical Context

The AC164349 implements a passive, zero-insertion-force (ZIF) socket interface between the MPLAB PM3 programmer and target PIC18F8xJ72 microcontrollers in 80L TQFP packages. It routes all VPP, VDD, VSS, PGD, PGC, and MCLR signals with impedance-controlled paths meeting Microchip's PM3 timing specifications for high-yield production programming.

No onboard logic or voltage translation is present - signal integrity relies on precise PCB layout matching the PM3's output drive strength and timing margins. Mechanical alignment is secured via four corner mounting holes compatible with standard PM3 adapter plates.

FAQ

What is the primary function of the AC164349 socket module?

The AC164349 socket module provides a mechanically and electrically optimized interface between the MPLAB PM3 programmer and PIC18F86J72-PT or PIC18F87J72-PT microcontrollers in 80L TQFP packages. It enables high-reliability, high-cycle-count programming in production settings without soldering or custom fixtures. The AC164349 does not contain active circuitry - its design focuses exclusively on signal fidelity and mechanical durability during repeated device insertion.

Which PIC microcontroller variants are explicitly supported by the AC164349?

The AC164349 is explicitly validated for PIC18F86J72-PT and PIC18F87J72-PT devices in 80-lead TQFP (12×12 mm) packages. Microchip's Device Tool Selector (DTS) confirms this support; no other PIC18F8xJ72 variants or package types (e.g., QFN or LQFP-64) are listed as compatible with the AC164349. Always verify current DTS entries before deployment.

Can the AC164349 be used with programmers other than the MPLAB PM3?

No - the AC164349 is mechanically and electrically designed solely for use with the MPLAB PM3 (DV007004). Its pinout, signal routing, and mounting interface are incompatible with MPLAB ICD 3, PICkit 4, or third-party programmers. Attempting integration with non-PM3 systems risks signal misalignment, timing violations, or physical damage to the socket or target device.

What is the maximum operating temperature rating for the AC164349?

The AC164349 is rated for continuous operation from 0°C to +70°C ambient temperature, consistent with industrial production floor conditions. This rating reflects thermal validation during repeated insertion cycles and sustained VPP/VDD stress testing. Operation outside this range may degrade contact resistance or cause plastic housing deformation, compromising programming yield.

Does the AC164349 require firmware or driver updates to function?

No - the AC164349 is a passive hardware interface with no embedded firmware, memory, or programmable logic. It functions immediately when mounted on a compatible MPLAB PM3 system running firmware v3.20 or later. Configuration is handled entirely by the PM3 host software and DTS-selected device profile; no user-side updates or calibration of the AC164349 itself are required.
