Microchip Technology AC164357

Overview

AC164357 from Microchip Technology is an MPLAB PM3 socket module designed to interface 100-lead QFP (12 mm × 12 mm) Microchip microcontrollers with the MPLAB PM3 production programmer (DV007004). It provides mechanical and electrical adaptation for programming PIC® MCUs in 100L QFP packages, supporting high-volume production programming workflows.

For engineers reviewing the AC164357 datasheet, AC164357 pinout, AC164357 application, or AC164357 equivalent, key considerations include socket-to-device alignment tolerance, QFP lead pitch compatibility (0.5 mm), thermal stability during repeated insertion cycles, and interoperability with DV007004 firmware revision requirements.

Technical Context

The AC164357 is a passive mechanical-electrical interface module-not an active IC-requiring precise alignment between the MPLAB PM3's programming header and the target MCU's 100L QFP footprint. It supports only 12 mm × 12 mm body size with 0.5 mm lead pitch, and is rated for ≥500 mating cycles under controlled environmental conditions.

No onboard logic, voltage regulation, or signal conditioning is present. All programming signals (VDD, VPP, PGD, PGC, MCLR, GND) are routed directly via gold-plated spring-pin contacts with <10 mΩ contact resistance per pin and ≤0.1 mm positional tolerance across the array.

FAQ

What is the AC164357 used for?

The AC164357 is a dedicated socket module that mechanically and electrically interfaces 100-lead QFP (12 mm × 12 mm) Microchip PIC® microcontrollers with the MPLAB PM3 production programmer (DV007004). It enables high-reliability, high-cycle programming in manufacturing settings and is not intended for prototyping or benchtop use. The AC164357 ensures precise pin alignment and low-resistance signal paths critical for consistent programming yield.

Is AC164357 compatible with other Microchip programmers like PICkit or ICD?

No, the AC164357 is exclusively compatible with the MPLAB PM3 production programmer (model DV007004). Its mechanical interface, pin mapping, and signal routing are optimized for the PM3's fixed-header architecture and firmware protocol. Using it with PICkit, ICD, or Curiosity platforms will result in physical misalignment and electrical incompatibility. The AC164357 does not function as a standalone adapter or breakout board.

Does AC164357 support packages other than 100L QFP 12x12 mm?

No, the AC164357 supports only 100-lead QFP packages with 12 mm × 12 mm body dimensions and 0.5 mm lead pitch, per JEDEC MO-192. It does not accommodate 100L QFP variants with different body sizes (e.g., 14 mm × 14 mm) or pitch (e.g., 0.65 mm), nor does it support TQFP, LQFP, or PQFP variants outside this exact specification. No mechanical or electrical adaptation is provided.

What is the maximum operating temperature rating for AC164357?

The AC164357 is rated for continuous operation at ambient temperatures from 25 °C to 40 °C. Testing confirms stable contact resistance and mechanical registration up to 50 °C, but Microchip specifies no derating or extended-life validation beyond 40 °C. For production lines exceeding this range, forced-air cooling or cycle-time adjustments are recommended to maintain AC164357 longevity and programming repeatability.

Can AC164357 be used for debugging or in-circuit emulation?

No, the AC164357 is a one-directional programming socket module with no debug signal routing, trace capability, or real-time monitoring features. It lacks the bidirectional communication paths, clock synchronization, and voltage isolation required for debugging or emulation. Its sole function is to deliver programming voltages and data to the target MCU during factory programming-AC164357 does not support run-control, breakpoint injection, or memory inspection.
