Microchip Technology AC164386

Overview

AC164386 from Microchip Technology is a socket module designed for programming PIC18F9xJ94 microcontrollers in 100-lead TQFP (12×12 mm) package using the MPLAB PM3 programmer (DV007004). It supports -PT package variants and enables reliable device programming in production and development environments.

For engineers reviewing the AC164386 datasheet, AC164386 pinout, AC164386 application, or AC164386 equivalent, key considerations include socket compatibility with PIC18F9xJ94, mechanical alignment to 0.5 mm pitch 100L TQFP, support for MPLAB PM3 interface, and verification via Microchip's Device Tool Selector (DTS).

Technical Context

The AC164386 is a passive mechanical and electrical interface adapter - not an active IC - that bridges the MPLAB PM3 programmer to target PIC18F9xJ94 devices in 100L TQFP (-PT) packaging. It provides precise ZIF socket contact alignment and signal routing for VDD, VSS, PGD, PGC, MCLR, and VPP programming lines.

No onboard logic, voltage regulation, or protocol translation is implemented. All timing, voltage levels, and programming sequences are controlled entirely by the host MPLAB PM3 unit and firmware, per Microchip's PIC ICSP™ specification.

Key Specifications

Supply support for AC164386 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

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

The AC164386 belongs to Microchip's MPLAB® programming hardware ecosystem and was engineered specifically to extend PM3 compatibility to high-pin-count PIC18F9xJ94 devices in 100L TQFP packages.

FAQ

Does AC164386 support devices other than PIC18F9xJ94?

No. AC164386 is mechanically and electrically tuned only for PIC18F9xJ94 in 100L TQFP (-PT) packaging. It does not support other families or package variants, even if pin-count or pitch appears similar. Always verify compatibility using Microchip's Device Tool Selector before use.

Is AC164386 compatible with MPLAB ICD or PICkit programmers?

No. AC164386 is designed exclusively for use with the MPLAB PM3 programmer (DV007004). It lacks the signal conditioning, voltage translation, or firmware handshake required for ICD or PICkit platforms. Using it with incompatible programmers may result in communication failure or damage.

What is the maximum operating temperature rating for AC164386?

AC164386 has no active components and no specified thermal rating. Its ZIF socket and PCB substrate are rated for standard lab and production ambient conditions (0–50°C). Continuous exposure above 60°C may degrade socket contact integrity or solder joint reliability over time.

Does AC164386 require firmware updates or driver installation?

No. AC164386 is a passive hardware interface with no embedded firmware or USB/serial interface. It requires no drivers or software updates. Operation depends solely on MPLAB PM3 firmware version 3.40 or later and correct socket selection in MPLAB X IDE.

Can AC164386 be used for in-circuit debugging?

No. AC164386 supports only ICSP™ programming - not real-time debugging. It lacks debug clock (PGC) and data (PGD) signal buffering or level-shifting needed for active debug sessions. For debugging, use an ICD4 or REAL ICE with appropriate debug headers.
