Microchip Technology AC164385

Overview

AC164385 from Microchip Technology is a dedicated socket module for programming PIC32MZ microcontrollers in 144-lead TQFP (16×16 mm, -PH package code) using the MPLAB PM3 Programmer (DV007004). It provides mechanical and electrical interface alignment, supports high-reliability IC insertion/removal, and enables in-system programming verification for embedded firmware development.

For engineers reviewing the AC164385 datasheet, AC164385 pinout, AC164385 application, or AC164385 equivalent, key considerations include socket-to-device footprint compatibility, PM3 programmer interface requirements, TQFP-144 (-PH) mechanical registration, and PIC32MZ family voltage-level support during programming cycles.

Technical Context

The AC164385 is a passive mechanical-electrical interface module-not an active IC-designed exclusively for use with the MPLAB PM3 Programmer (DV007004) to program PIC32MZ devices in 144L TQFP (-PH) packages. It implements zero-insertion-force (ZIF) socket mechanics and maintains signal integrity for VDD, VSS, PGD, PGC, MCLR, and VPP lines per Microchip's PM3 programming specification.

No onboard logic, power regulation, or protocol translation is present. All timing, voltage level shifting, and programming command execution are handled by the host DV007004 unit. The module conforms to Microchip's mechanical alignment standard for 16×16 mm TQFP bodies with 0.5 mm pitch and 144 leads.

FAQ

What is the AC164385 used for?

The AC164385 is a socket module that enables programming of Microchip PIC32MZ microcontrollers in 144-lead TQFP (-PH) packages using the MPLAB PM3 Programmer (DV007004). It is not a standalone programmer but a mechanical and electrical interface accessory. The AC164385 ensures precise alignment, reliable contact, and repeatable programming cycles for PIC32MZ devices during firmware development and small-batch production.

Is the AC164385 compatible with PIC32MX or PIC24 devices?

No. The AC164385 is mechanically and electrically designed only for PIC32MZ devices in the 144L TQFP (-PH) package. It is not validated for PIC32MX, PIC24, dsPIC, or any other Microchip MCU family. Using it with incompatible devices may result in misalignment, poor contact, or programming failure. Always verify compatibility via Microchip's Device Tool Selector before selecting the AC164385.

Does the AC164385 require external power or drivers?

No. The AC164385 is a passive socket module with no active circuitry. It draws no external power and requires no software drivers. Power, clock, and programming signals are supplied entirely by the connected MPLAB PM3 Programmer (DV007004). The AC164385 functions solely as a precision-machined interface between the DV007004 and the target PIC32MZ device.

Can the AC164385 be used with third-party programmers?

No. The AC164385 is designed exclusively for use with the official Microchip MPLAB PM3 Programmer (DV007004). Its 20-pin IDC interface, pinout mapping, and signal routing match only that unit. Third-party or clone programmers lack the required mechanical interface, firmware handshake, and voltage-level compliance needed for safe and reliable operation with the AC164385.

What does "-PH package code" mean for the AC164385?

The "-PH" suffix denotes Microchip's specific package variant for 144-lead TQFP devices with 16×16 mm body size and 0.5 mm lead pitch. The AC164385 socket is dimensionally and pin-registered to this exact variant. Devices marked with other codes (e.g., -P or -PT) may have different thermal pad configurations or lead profiles and are not guaranteed to seat correctly or make full contact in the AC164385 socket.
