Microchip Technology AC164304

Overview

AC164304 from Microchip Technology is an 80-lead TQFP socket module designed for use with the MPLAB PM3 Universal Device Programmer to interface with 80-pin TQFP-packaged PICmicro® and dsPIC30F microcontrollers during programming and verification. It provides mechanical alignment, reliable electrical contact, and hot-swap compatibility with the PM3's 40-pin programmable socket interface via multi-pin connector.

For engineers reviewing the AC164304 datasheet, AC164304 pinout, AC164304 application, or AC164304 equivalent, this socket module enables rapid device programming in PC Host, Standalone, and Safe modes-supporting high-throughput production, SQTP™ serialization, and field-upgradable firmware on the MPLAB PM3 platform.

Technical Context

The AC164304 socket module is a passive hardware interface that maps all 80 pins of a TQFP package to the MPLAB PM3's configurable 40-pin socket interface using internal signal routing and pin multiplexing logic. It supports ICSP™ (In-Circuit Serial Programming) signals including PGD, PGC, VPP, VDD, and VSS across dedicated contact paths.

Designed for mechanical durability and repeatable insertion cycles, the AC164304 uses gold-plated contacts and precision-machined cavity alignment to maintain signal integrity during programming of devices up to 512 KB Flash memory. It requires no external power or configuration and operates transparently within the MPLAB IDE environment.

FAQ

What is the AC164304 used for?

The AC164304 is an 80-lead TQFP socket module for the MPLAB PM3 programmer. It enables physical and electrical interfacing between the PM3 base unit and 80-pin TQFP-packaged PICmicro® and dsPIC30F microcontrollers during programming, verification, and SQTP™ serialization. The AC164304 does not contain active circuitry-it functions solely as a precision mechanical and contact interface.

Does the AC164304 require drivers or firmware installation?

No, the AC164304 is a passive socket module with no embedded electronics, firmware, or communication interface. It requires no drivers, configuration files, or software setup. Once installed on the MPLAB PM3 base unit, it is automatically recognized and used by the MPLAB IDE and PM3 firmware during device programming sessions involving 80-pin TQFP parts.

Which Microchip devices are supported by the AC164304?

The AC164304 supports all Microchip PICmicro® and dsPIC30F microcontrollers housed in 80-lead TQFP packages, including but not limited to PIC18F8722, PIC18F87K22, dsPIC30F6014A, and dsPIC30F6015. Full compatibility is confirmed in Microchip document DS51444A and the MPLAB PM3 device support list.

Can the AC164304 be used with older PROMATE® II programmers?

No-the AC164304 is designed exclusively for the MPLAB PM3 platform. To use PROMATE® II socket modules with the PM3, Microchip provides the AC164350 adapter. The AC164304 itself is not mechanically or electrically compatible with PROMATE® II base units due to differing connector types, pin assignments, and signal routing architecture.

Is the AC164304 RoHS compliant?

Yes, the AC164304 complies with RoHS Directive 2011/65/EU. Microchip confirms RoHS compliance for all MPLAB PM3 socket modules shipped after Q1 2004, including AC164304, as documented in Microchip's Material Declaration and Environmental Compliance Statements referenced in DS51444A.
