Microchip Technology AC164302

Overview

AC164302 from Microchip Technology is a socket module designed for the MPLAB PM3 Universal Device Programmer, enabling programming of 16-lead and 28-lead SOIC-packaged PICmicro® and dsPIC30F devices. It features dual-lead-count compatibility (16L at 0.150″ width and 28L at 0.300″ width), gold-plated contacts for reliable signal integrity, and mechanical alignment with the PM3's 40-pin programmable socket interface.

For engineers reviewing the AC164302 datasheet, AC164302 pinout, AC164302 application, or AC164302 equivalent, this module supports production-grade device programming in PC-host, standalone, and secure SQTP modes - critical for high-volume PIC MCU firmware deployment, engineering validation labs, and automated programming stations requiring socket modularity and legacy PROMATE II interoperability via adapter AC164350.

Technical Context

The AC164302 is a passive mechanical and electrical interface module-not an IC or active component-and functions exclusively as a field-replaceable socket adapter between the MPLAB PM3's universal 40-pin programmable header and target SOIC devices. It provides precise lead pitch matching (1.27 mm for 16L, 1.27 mm for 28L) and conforms to JEDEC MS-012 and MO-153 standards for SOIC packages.

No onboard logic, voltage regulation, or signal conditioning is present. All programming signals (VDD, VPP, PGD, PGC, MCLR, GND) are routed directly from the PM3's socket pins through the module's contact array to the device leads, preserving timing integrity and ICSP™ protocol compliance per Microchip's specification DS51444A.

FAQ

What is the AC164302 used for?

The AC164302 is a socket module for the MPLAB PM3 programmer that enables reliable, repeatable programming of 16-lead and 28-lead SOIC-packaged Microchip PICmicro® and dsPIC30F devices. It mounts directly onto the PM3's 40-pin socket interface and provides mechanical and electrical adaptation - no firmware, drivers, or configuration is required for AC164302 operation.

Does the AC164302 support both 16L and 28L SOIC packages simultaneously?

Yes - the AC164302 is mechanically designed to accept either 16-lead SOIC (0.150″ width) or 28-lead SOIC (0.300″ width) devices using the same module. Its dual-width cavity and adjustable retention mechanism eliminate the need for separate sockets, reducing inventory and setup time when programming mixed SOIC variants with the AC164302.

Is the AC164302 compatible with the MPLAB PM3 only, or does it work with other programmers?

The AC164302 is specifically designed for and mechanically/electrically compatible only with the MPLAB PM3 Universal Device Programmer. It is not intended for use with PICSTART® Plus, MPLAB ICD 2, or third-party programmers. Its 40-pin male header and pinout mapping align exclusively with the PM3's socket architecture and ICSP™ signal routing.

Can the AC164302 be used with PROMATE II socket modules?

No - the AC164302 is a native PM3 socket module. To use existing PROMATE II socket modules with the MPLAB PM3, Microchip provides the AC164350 adapter (sold separately). The AC164302 itself does not interface with or convert PROMATE II modules; it replaces them for SOIC applications within the PM3 ecosystem.

What standards or specifications does the AC164302 comply with?

The AC164302 complies with JEDEC standards MS-012 (16L SOIC) and MO-153 (28L SOIC) for body dimensions and lead form. Its contact layout and signal routing follow Microchip's MPLAB PM3 Hardware Interface Specification (DS51444A), ensuring full compatibility with ICSP™ programming protocols and voltage-level requirements for all supported PICmicro® and dsPIC30F devices.
