Microchip Technology AC164308

Overview

AC164308 from Microchip Technology is a 68-lead PLCC socket module designed for use with the MPLAB PM3 Universal Device Programmer to support in-system and socket-based programming of Microchip PICmicro® and dsPIC30F devices in 68-pin PLCC packages. It features multi-pin connector interface, hot-swappable configuration, and mechanical alignment for reliable ZIF contact engagement.

For engineers reviewing the AC164308 datasheet, AC164308 pinout, AC164308 application, or AC164308 equivalent, this socket module enables rapid device programming across production, lab validation, and firmware development workflows where PLCC-packaged microcontrollers require verified physical interface compatibility with the MPLAB PM3 platform.

Technical Context

The AC164308 implements a passive, zero-insertion-force (ZIF) socket interface with 68 gold-plated contacts aligned to JEDEC MO-047B PLCC-68 footprint. It routes all device signals-including VDD, VSS, MCLR, PGD, PGC, and I/O pins-directly to the MPLAB PM3's programmable 40-pin socket interface via a standardized multi-pin ribbon cable assembly.

No onboard logic or active circuitry is present; signal integrity relies on matched trace lengths and impedance-controlled routing within the MPLAB PM3 main unit. Firmware-level device support is handled entirely by the host programmer, not the socket module itself.

FAQ

What is the AC164308 used for?

The AC164308 is a dedicated 68-lead PLCC socket module for the MPLAB PM3 Universal Device Programmer. It enables physical interfacing and programming of Microchip PICmicro® and dsPIC30F devices housed in 68-pin PLCC packages. The AC164308 must be installed on the MPLAB PM3 unit to program compatible devices in socket mode, supporting both engineering validation and production programming workflows.

Does the AC164308 include firmware or require configuration?

No, the AC164308 is a passive hardware interface with no firmware, memory, or configuration logic. It functions solely as a mechanical and electrical bridge between the PLCC device and the MPLAB PM3's programmable socket bus. All programming intelligence resides in the MPLAB PM3 unit and its host software - the AC164308 requires no setup, calibration, or update.

Which Microchip devices are confirmed compatible with the AC164308?

The AC164308 supports all Microchip PLCC-68 packaged devices listed in the MPLAB PM3 device support matrix, including PIC16F877A, PIC18F8720, PIC18F87J11, dsPIC30F6014A, and dsPIC30F6015. Compatibility is verified through Microchip's official device programming specification DS51444A and MPLAB PM3 release notes.

Can the AC164308 be used with older PROMATE II programmers?

No - the AC164308 is mechanically and electrically designed exclusively for the MPLAB PM3 platform. To use legacy PROMATE II socket modules with the MPLAB PM3, Microchip provides the AC164350 adapter; however, the AC164308 itself is not backward-compatible with PROMATE II hardware or its interface architecture.

Is the AC164308 RoHS-compliant and lead-free?

Yes, the AC164308 conforms to Microchip's RoHS-5 compliance standard (lead-free except for exemptions under Annex III of Directive 2011/65/EU). Its housing, contacts, and internal wiring meet halogen-free and lead-free soldering requirements for reflow and hand-soldering processes per J-STD-020 and IPC-J-STD-609.
