Microchip Technology AC164418

Overview

AC164418 from Microchip Technology is a dedicated socket module for programming PIC32MX470F512L microcontrollers in 124-pin VTLA (Very Thin Leadless Array) packages with 9×9 mm footprint and -TL package code. It interfaces exclusively with the MPLAB PM3 Programmer (DV007004) and enables in-system programming of flash memory, configuration bits, and user ID locations.

For engineers reviewing the AC164418 datasheet, AC164418 pinout, AC164418 application, or AC164418 equivalent, this module is selected specifically for reliable, low-insertion-force programming of PIC32MX470F512L devices in production and development environments where VTLA package handling and signal integrity during programming are critical.

Technical Context

The AC164418 implements a passive, zero-insertion-force (ZIF-free) socket interface with spring-loaded pogo pins aligned to the 124-terminal VTLA land pattern. It supports full-voltage ISP (In-System Programming) at 3.3 V and includes ESD protection on all signal paths per IEC 61000-4-2 Level 4.

Designed for use only with the MPLAB PM3 Programmer, the AC164418 routes VDD, VSS, PGD, PGC, MCLR, and auxiliary control signals without level shifting or buffering - preserving timing compliance for PIC32MX device programming protocols including LVP and HVP modes.

FAQ

What devices does the AC164418 support?

The AC164418 supports only the PIC32MX470F512L microcontroller in the 124-pin VTLA package with -TL package code. It is not compatible with other PIC32MX variants, PIC32MZ, or non-Microchip devices. Confirmation must be made using Microchip's Device Tool Selector at microchip.com/dtsapp before deployment.

Is AC164418 compatible with the MPLAB ICD 4 or PICkit 4?

No, AC164418 is designed exclusively for use with the MPLAB PM3 Programmer (DV007004). It lacks the electrical interface and mechanical alignment features required for ICD 4 or PICkit 4 programmers. Attempting integration may result in unreliable programming or physical damage to the socket or target device.

Does AC164418 require firmware or driver installation?

No, AC164418 is a passive hardware interface with no onboard logic or firmware. It requires only the MPLAB X IDE v5.45+ and MPLAB PM3 firmware v3.40+ installed on the host PC. The AC164418 itself functions as a mechanical and electrical bridge - no drivers or configuration files are associated with the AC164418.

Can AC164418 be used for debugging or only programming?

The AC164418 supports only programming operations - flash memory write, configuration bit set, and user ID programming - for the PIC32MX470F512L. It does not enable real-time debugging, breakpoints, or variable inspection. Debugging requires a separate debug probe such as the MPLAB ICD 4 or REAL ICE connected directly to the target board.

What is the recommended insertion force and alignment method for AC164418?

AC164418 uses precision-machined alignment posts and chamfered VTLA cavity edges to guide the PIC32MX470F512L into position. Insertion requires ≤15 N axial force applied evenly across the top surface; excessive lateral force or misalignment may deform pogo pins. Microchip recommends using the AC164418 mounting bracket (sold separately) for repeatable placement.
