Microchip Technology AC164416

Overview

AC164416 from Microchip Technology is a universal socket module designed for programming 80-lead TQFP (-PT package code) microcontrollers using the MPLAB PM3 Programmer (DV007004). It supports devices in the 33EP/CH family, features a 12×12 mm footprint, and enables reliable ZIF-based device insertion and electrical contact for production and development programming.

For engineers reviewing the AC164416 datasheet, AC164416 pinout, AC164416 application, or AC164416 equivalent, key considerations include TQFP-80 (-PT) mechanical compatibility, PM3 programmer interface requirements, ZIF socket actuation force, thermal tolerance during repeated programming cycles, and alignment accuracy for fine-pitch lead placement.

Technical Context

The AC164416 is a passive hardware interface module-not an IC or active component-and provides mechanical and electrical bridging between the MPLAB PM3 Programmer and target 80L TQFP devices. It implements zero-insertion-force (ZIF) actuation with spring-loaded contacts rated for ≥50,000 mating cycles and maintains coplanarity within ±0.05 mm across all 80 terminals.

It is mechanically dimensioned to match the 12×12 mm body size of TQFP-80 packages with -PT suffix, and its socket cavity depth, lead pitch accommodation (0.5 mm), and corner keying align precisely with JEDEC MO-220DA standards for TQFP-80.

FAQ

What is the AC164416 used for?

The AC164416 is a universal ZIF socket module that enables programming of Microchip 33EP/CH-series microcontrollers in 80-lead TQFP (-PT) packages using the MPLAB PM3 Programmer (DV007004). It is not a standalone electronic component but a mechanical-electrical interface tool used in firmware loading, device testing, and production programming workflows where repeatable, low-damage device insertion is required. The AC164416 does not perform logic, signal conditioning, or power regulation.

Which Microchip devices are compatible with the AC164416?

The AC164416 supports only Microchip microcontrollers packaged in 80-lead TQFP with the -PT suffix, including specific members of the dsPIC33EP and PIC24CH families. Compatibility must be verified via Microchip's Device Tool Selector (dtsapp.microchip.com); it does not support QFN, SOIC, SSOP, or non–TQFP-80 variants-even if pin-count matches-due to mechanical and contact layout differences inherent to the AC164416 socket cavity design.

Can the AC164416 be used with programmers other than the MPLAB PM3?

No, the AC164416 is mechanically and electrically designed exclusively for use with the MPLAB PM3 Programmer (model DV007004). Its pin mapping, signal routing, and physical mounting interface are incompatible with PICkit 4, MPLAB ICD 4, MPLAB Snap, or third-party programmers. Attempting integration with non-PM3 systems may result in misalignment, contact failure, or damage to the socket or target device.

What is the maximum operating temperature rating for the AC164416 during programming cycles?

The AC164416 is rated for continuous operation at ambient temperatures from 0°C to 50°C. Its ZIF contacts and housing materials maintain dimensional stability and contact resistance integrity within this range during repeated programming sessions. It is not rated for reflow, soldering, or exposure above 60°C, as thermal stress beyond specification may degrade contact spring fatigue life or socket alignment accuracy over time.

Does the AC164416 require calibration or firmware updates?

No, the AC164416 is a passive hardware module with no embedded firmware, sensors, or programmable elements. It requires no calibration, driver installation, or firmware updates. Its functionality depends solely on mechanical precision and electrical continuity between the PM3 programmer header and the target TQFP device. Users should inspect contacts visually and verify continuity periodically-but no software or configuration intervention is associated with the AC164416 itself.
