Microchip Technology AC164311

Overview

AC164311 from Microchip Technology is a 44-lead MQFP/SOIC socket module designed for use with the MPLAB PM3 Universal Device Programmer. It provides mechanical and electrical interface compatibility for 44-pin MQFP and SOIC-packaged Microchip PICmicro® and dsPIC30F devices, supports ICSP™ programming, and enables field-reconfigurable device programming without requiring PCB-level changes.

For engineers reviewing the AC164311 datasheet, AC164311 pinout, AC164311 application, or AC164311 equivalent, this socket module serves as a critical hardware interface component in production programming, firmware validation, and development lab workflows where rapid device changeover and secure serial number programming (SQTP™) are required.

Technical Context

The AC164311 socket module interfaces directly with the MPLAB PM3's 40-pin programmable socket interface via a multi-pin connector, translating the programmer's universal pin mapping to the specific 44-pin MQFP/SOIC footprint. It supports In-Circuit Serial Programming (ICSP™) signals including PGD, PGC, VPP, VDD, and VSS, and maintains signal integrity for high-speed programming of flash-based MCUs.

This module operates exclusively in conjunction with the MPLAB PM3 unit (DV007004) and requires no standalone power or configuration. Its design enables plug-and-play compatibility with the PM3's firmware-controlled socket selection logic and integrates with SQTP™ serialization during PC-host mode programming sessions.

FAQ

What is the primary function of the AC164311 socket module?

The AC164311 socket module provides mechanical and electrical interface adaptation between the MPLAB PM3 Universal Device Programmer and 44-pin MQFP or SOIC-packaged Microchip PICmicro® and dsPIC30F devices. It enables reliable, repeatable programming without soldering or custom fixtures, and is essential for production programming and firmware validation workflows using the AC164311.

Does AC164311 require separate power or configuration software?

No, the AC164311 is a passive socket module that draws all necessary power and control signals from the MPLAB PM3 unit (DV007004). It requires no external power supply, drivers, or configuration utilities - operation is fully managed by the PM3's firmware and MPLAB IDE when used in PC-host mode. The AC164311 functions only as an interface adapter within the PM3 ecosystem.

Can AC164311 be used with older Microchip programmers like PICSTART® Plus or PROMATE® II?

No, the AC164311 is mechanically and electrically designed exclusively for the MPLAB PM3 Universal Device Programmer. It is not compatible with PICSTART® Plus or PROMATE® II units. However, an adapter (AC164350) allows legacy PROMATE® II socket modules to be used on the MPLAB PM3 - the AC164311 itself does not provide backward compatibility.

Is AC164311 compatible with both MQFP and SOIC packages having 44 leads?

Yes, the AC164311 socket module is explicitly designed to accommodate both 44-lead MQFP and 44-lead SOIC packages, as confirmed in Microchip's ordering information and DS51444A documentation. Its dual-footprint support eliminates the need for separate modules and reduces inventory complexity for labs supporting multiple Microchip MCU variants using the AC164311.

Does AC164311 support Serialized Quick Turn Programming (SQTP™)?

Yes, the AC164311 fully supports SQTP™ functionality when used with the MPLAB PM3 in PC-host mode and MPLAB IDE. It routes all required programming and serialization signals (including VPP, PGD, PGC, and VDD) without modification, enabling unique serial number injection into device memory during automated programming sequences - a core capability enabled by the AC164311.
