Microchip Technology AC164408

Overview

AC164408 from Microchip Technology is a PM3 socket module designed for programming 8-lead DFN and 20-lead QFN ICs with (4×4) mm body size, supporting -MD and -ML package codes, and compatible exclusively with the MPLAB PM3 Programmer (DV007004) in production and development environments.

For engineers reviewing the AC164408 datasheet, AC164408 pinout, AC164408 application, or AC164408 equivalent, this module enables reliable in-system programming of Microchip PIC and dsPIC microcontrollers in compact DFN/QFN packages-critical for rapid prototyping, firmware validation, and small-batch programming workflows where mechanical alignment, thermal stability, and ZIF contact integrity are essential.

Technical Context

The AC164408 is a passive mechanical interface-not an active electronic component-with no voltage, current, or timing specifications. It provides precision-machined spring-pin contacts aligned to JEDEC-standard 0.5 mm pitch for both 8L DFN (-MD) and 20L QFN (-ML) footprints, enabling shared socket reuse across two distinct package families on the same PM3 base unit.

Its dual-package support eliminates need for separate sockets when programming devices such as PIC16F18326 (8L DFN) and PIC32MX150F128B (20L QFN), reducing tooling cost and floor space while maintaining full compliance with Microchip's Device Tool Selector validation requirements.

FAQ

Does AC164408 support programming of PIC32MZ EC devices?

No. AC164408 supports only 8L DFN (-MD) and 20L QFN (-ML) packages with (4×4) mm body size. PIC32MZ EC devices use larger packages (e.g., 64L TQFP or 121L BGA) not covered by AC164408. Verify compatibility using Microchip's Device Tool Selector before deployment.

Can AC164408 be used with the MPLAB ICD 4 or PICkit 4?

No. AC164408 is mechanically and electrically designed for use exclusively with the MPLAB PM3 Programmer (DV007004). It lacks the interface logic and power delivery architecture required by ICD 4 or PICkit 4, and no adapter or firmware update enables cross-programmer compatibility.

What is the maximum operating temperature rating for AC164408?

AC164408 has no active electronics and therefore no rated operating temperature range. Its polymer housing and beryllium-copper contacts are rated for ambient use between –20°C and +70°C per Microchip's mechanical specification sheet, sufficient for standard lab and production floor conditions.

Is AC164408 RoHS compliant and lead-free?

Yes. AC164408 complies with RoHS Directive 2011/65/EU and uses lead-free solderable finishes on all contact surfaces. Microchip confirms full compliance in its official part documentation and certifies material content via IPC-1752A reporting.

Does AC164408 require calibration or firmware updates?

No. AC164408 is a passive mechanical socket module with no embedded firmware, sensors, or programmable elements. It requires no calibration, driver installation, or firmware updates-only physical cleaning and visual inspection of contact pins prior to each use.
