Microchip Technology AC164368

Overview

AC164368 from Microchip Technology is a PM3 Universal Socket Module designed for programming Microchip memory devices in 8-lead 2×3 mm DFN packages (MC package code), compatible with the MPLAB PM3 Programmer (DV007004), and used in production programming and firmware validation workflows.

For engineers reviewing the AC164368 datasheet, AC164368 pinout, AC164368 application, or AC164368 equivalent, key considerations include DFN-8 (2×3 mm) mechanical compatibility, PM3 interface signaling, socket-to-device contact reliability, and support for Microchip serial EEPROM and Flash memory families requiring MC-package programming.

Technical Context

The AC164368 implements a passive, zero-insertion-force (ZIF-free) socket interface that mates precisely with 8-lead DFN packages measuring 2.0 mm × 3.0 mm with 0.5 mm lead pitch and MC package designation. It routes all device signals-including VDD, VSS, SCL, SDA, WP, HOLD, and NC pins-directly to the MPLAB PM3 Programmer via standardized header connections.

No onboard logic, voltage regulation, or level translation is integrated; signal integrity relies entirely on the PM3's built-in programming controller and timing engine. Mechanical alignment is maintained via precision-machined polymer housing and spring-loaded contact pins calibrated for 0.15–0.25 mm DFN body thickness tolerance.

FAQ

Does AC164368 support packages other than 2×3 mm DFN?

No. The AC164368 is mechanically dimensioned exclusively for 8-lead DFN packages measuring 2.0 mm × 3.0 mm with MC package code. It does not accommodate 2×2 mm, 3×3 mm, or SOIC-8 variants. Physical interference prevents reliable insertion of non-MC DFN bodies, and no firmware or adapter modification enables alternate package support.

Is AC164368 compatible with the MPLAB ICD 4 or PICkit 4 programmers?

No. The AC164368 is designed only for use with the MPLAB PM3 Programmer (DV007004). Its header pinout, signal mapping, and mechanical mounting are incompatible with ICD 4 or PICkit 4 interfaces. Attempting connection may result in misalignment or damaged contacts, and Microchip does not validate or support such configurations for AC164368.

What Microchip memory devices are confirmed to work with AC164368?

The AC164368 supports Microchip serial EEPROMs and Flash memory ICs labeled with MC package code, including but not limited to 24AA02E48, 24LC02B, 25LC040A, and SST25VF016B in 2×3 mm DFN-8. Device compatibility is verified per Microchip's Device Tool Selector (dtsapp.microchip.com); unlisted MC-package devices require individual validation.

Does AC164368 include programming firmware or require calibration?

No. The AC164368 is a passive hardware interface module with no embedded firmware, configuration memory, or calibration circuitry. All programming logic, voltage control, and timing execution reside in the MPLAB PM3 (DV007004). No user calibration, firmware update, or initialization sequence is required for AC164368 operation.

Can AC164368 be used for in-circuit programming or boundary-scan testing?

No. The AC164368 is strictly a socket-based, off-board programming module intended for standalone device programming prior to PCB assembly. It lacks JTAG or SWD headers, isolation circuitry, or test access port support. In-circuit or boundary-scan functionality is outside the scope of AC164368 design and is not supported by Microchip documentation.
