Microchip Technology AC164306

Overview

AC164306 from Microchip Technology is a 20-lead Thin Shrink Small Outline Package (TSSOP) socket module designed for use with the MPLAB PM3 Universal Device Programmer. It provides mechanical and electrical interface compatibility for programming 20-pin TSSOP-packaged PICmicro® and dsPIC30F microcontrollers, supports ICSP™ connectivity, and enables rapid device programming in PC Host, Standalone, or Safe mode.

For engineers reviewing the AC164306 datasheet, AC164306 pinout, AC164306 application, or AC164306 equivalent, this socket module is essential for reliable, high-fidelity programming of 20L TSSOP Microchip MCUs in production, lab, and development environments where package-specific contact integrity and repeatable ZIF engagement are critical.

Technical Context

The AC164306 socket module interfaces directly with the MPLAB PM3's 40-pin programmable socket interface via a multi-pin connector, enabling configuration-specific signal routing to match 20L TSSOP device pinouts. It supports In-Circuit Serial Programming (ICSP™) signals including PGD, PGC, VDD, VSS, and MCLR, and maintains full compatibility with SQTP™ serialization when used in PC Host mode.

This module operates exclusively as a passive mechanical/electrical adapter-no firmware, logic, or active circuitry-and relies on the host MPLAB PM3 unit for voltage regulation, timing control, and protocol execution. It is field-replaceable, hot-swappable, and validated for >100,000 insertion cycles per specification.

FAQ

What is the AC164306 used for?

The AC164306 is a dedicated 20-lead TSSOP socket module for the MPLAB PM3 programmer. It enables physical and electrical interfacing between the MPLAB PM3 unit and Microchip PICmicro® or dsPIC30F microcontrollers housed in 20L TSSOP packages. The AC164306 ensures precise pin alignment, low-contact-resistance signal paths, and repeatable ZIF actuation-critical for reliable high-volume programming and engineering validation of these devices.

Does the AC164306 require separate power or firmware?

No, the AC164306 is a passive mechanical socket module with no internal circuitry, power input, or firmware. It draws all necessary programming voltages, timing signals, and protocol logic from the host MPLAB PM3 unit (DV007004) via its 40-pin multi-pin interface. The AC164306 functions solely as a precision-machined, high-cycle-count adapter-no configuration, update, or external power is needed.

Is the AC164306 compatible with PROMATE II socket modules?

No, the AC164306 is not a PROMATE II socket module and does not plug directly into PROMATE II programmers. However, Microchip offers the AC164350 adapter to allow legacy PROMATE II socket modules-including those for TSSOP packages-to be used on the MPLAB PM3. The AC164306 itself is native to the MPLAB PM3 platform and requires no adapter.

Which Microchip devices are supported by the AC164306?

The AC164306 supports only Microchip PICmicro® and dsPIC30F microcontrollers packaged in 20-lead TSSOP (Thin Shrink Small Outline Package) format. Specific supported part numbers include-but are not limited to-PIC16F684, PIC16F688, PIC16F785, dsPIC30F2010, and dsPIC30F2011. Full compatibility is confirmed in the MPLAB PM3 Device Support List (DS51444A).

Can the AC164306 be used with other programmers besides the MPLAB PM3?

No, the AC164306 is mechanically and electrically designed exclusively for the MPLAB PM3 Universal Device Programmer (DV007004). Its multi-pin connector, pin mapping, and ZIF actuation mechanism are not compatible with PICSTART® Plus, MPLAB ICD 2, PICkit™, or any third-party programmer. Using the AC164306 outside the MPLAB PM3 system will not establish functional programming connectivity.
