Microchip Technology AC164402

Overview

AC164402 from Microchip Technology is a dedicated socket module for programming 28-lead UQFN (6×6 mm) microcontrollers using the MPLAB PM3 Programmer (DV007004); it supports devices with -2N package code, features zero-insertion-force (ZIF) contact design, and is mechanically optimized for precise alignment of fine-pitch UQFN leads in production programming environments.

For engineers reviewing the AC164402 datasheet, AC164402 pinout, AC164402 application, or AC164402 equivalent, this module is selected specifically for high-reliability in-circuit programming of 28L UQFN-packaged PIC and dsPIC microcontrollers during development, qualification, and low-volume manufacturing stages.

Technical Context

The AC164402 interfaces exclusively with the MPLAB PM3 Programmer via standard IDC-26 ribbon cable and 26-pin header; it provides direct signal routing for VDD, VSS, PGD, PGC, MCLR, and VPP without level shifting or buffering. Its mechanical interface conforms to JEDEC MO-220 UQFN footprint specifications for 28-lead, 0.4 mm pitch, 6×6 mm body size packages.

No onboard logic, voltage regulation, or protocol translation is implemented - the AC164402 functions purely as a passive, precision-machined mechanical and electrical bridge between the PM3's programming signals and the target UQFN device's bond pads.

Manufacturer

Microchip Technology is a U.S.-based semiconductor company specializing in microcontrollers, analog devices, and development tools for embedded control applications.

The AC164402 belongs to Microchip's MPLAB PM3 Socket Module family, designed to extend the programming capability of the DV007004 programmer to specific surface-mount IC packages without requiring custom fixtures or adapters.

FAQ

What devices are supported by the AC164402 socket module?

The AC164402 socket module supports Microchip PIC and dsPIC microcontrollers in 28-lead UQFN packages with 6×6 mm body size and -2N package code, including devices such as PIC32MX1xx/2xx series and select dsPIC33EP variants confirmed in the Device Tool Selector (dtsapp.microchip.com).

Is the AC164402 compatible with programmers other than the MPLAB PM3?

No - the AC164402 is engineered exclusively for use with the MPLAB PM3 Programmer (DV007004) and relies on its specific pinout, signal timing, and voltage levels; it is not electrically or mechanically compatible with MPLAB ICD, PICkit, or third-party programmers.

Does the AC164402 require firmware or driver installation?

No - the AC164402 is a passive hardware adapter with no embedded firmware, microcontroller, or software component; it requires only the MPLAB X IDE and MPLAB PM3 driver stack already bundled with the DV007004 programmer.

Can the AC164402 be used for debugging or only programming?

The AC164402 supports only in-circuit serial programming (ICSP) - it does not enable real-time debugging, breakpoints, or variable inspection; debugging functionality requires an active debugger (e.g., ICD4 or REAL ICE) and compatible debug header, not supported by the AC164402.

What is the recommended insertion force and lifetime rating for the AC164402 ZIF mechanism?

The AC164402 ZIF lever is rated for ≥5,000 mating cycles under proper handling; insertion force is minimized by precision-machined guide rails and spring-contact alignment - users must fully close the lever until audible click to ensure reliable contact before initiating programming.
