Microchip Technology AC164355

Overview

AC164355 from Microchip Technology is a production-grade socket module designed for programming 36-lead TLA (5×5 mm) microcontrollers using the MPLAB PM3 programmer (DV007004). It supports PIC® MCUs in thin leaded package code TLA, enables high-reliability contact during automated programming cycles, and is rated for ≥50,000 mating cycles. It is used in volume manufacturing of embedded control modules requiring repeatable device programming.

For engineers reviewing the AC164355 datasheet, AC164355 pinout, AC164355 application, or AC164355 equivalent, key selection criteria include TLA package compatibility, mechanical alignment tolerance (±0.05 mm), contact resistance (<20 mΩ), thermal stability up to 85°C, and integration with DV007004's ZIF actuation mechanism.

Technical Context

The AC164355 implements a zero-insertion-force (ZIF) socket interface with spring-loaded pogo pins arranged to match the 36-lead TLA footprint (0.5 mm pitch, 5×5 mm body). Its housing uses glass-filled LCP for dimensional stability under thermal cycling between 25°C and 85°C.

It interfaces exclusively with the MPLAB PM3 production programmer (DV007004) via a standardized 36-pin ribbon cable connection and requires no firmware or configuration-mechanical actuation alone establishes full electrical contact across all leads.

FAQ

What is the primary function of the AC164355 socket module?

The AC164355 socket module provides a zero-insertion-force (ZIF) interface for programming 36-lead TLA-packaged Microchip PIC® microcontrollers using the MPLAB PM3 programmer (DV007004). It ensures precise mechanical alignment and low-resistance electrical contact across all 36 leads during automated production programming cycles. The AC164355 is not a standalone programmer but a dedicated hardware interface module essential for repeatable, high-yield device programming in manufacturing.

Which microcontroller packages are compatible with AC164355?

The AC164355 supports only the 36-lead TLA (Thin Leadframe Array) package with 5×5 mm body size and 0.5 mm lead pitch. It is not compatible with QFN, TQFP, SOIC, or other TLA variants such as 44L or 28L. Compatibility is strictly limited to Microchip microcontrollers listed in the DTS Device Tool Selector (www.microchip.com/dtsapp) as supported by the AC164355 and DV007004 combination.

Can AC164355 be used with programmers other than MPLAB PM3 (DV007004)?

No. The AC164355 is mechanically and electrically designed exclusively for use with the MPLAB PM3 production programmer (DV007004). Its ZIF actuation mechanism, pin layout, and ribbon cable interface are proprietary to that system. Using AC164355 with any other programmer-including MPLAB ICD or PICkit-will result in misalignment, incomplete contact, or physical damage.

What is the expected lifetime of AC164355 under normal production use?

The AC164355 is rated for ≥50,000 mating cycles while maintaining contact resistance below 20 mΩ and positional accuracy within ±0.05 mm. This lifetime assumes operation within −40°C to +85°C ambient temperature and proper actuation force per DV007004 specifications. Degradation beyond this limit manifests as intermittent programming failures or increased VPP/VDD voltage drop during programming.

Does AC164355 require calibration or firmware updates?

No. The AC164355 is a passive mechanical-electrical interface module with no active components, firmware, or calibration requirements. It functions solely through precision-machined housing geometry and spring-loaded pogo pins. All timing, voltage regulation, and protocol handling are performed by the MPLAB PM3 (DV007004); the AC164355 contributes no signal conditioning or logic functionality.
