Microchip Technology AC164303

Overview

AC164303 from Microchip Technology is a 64-lead TQFP and SOIC socket module designed for use with the MPLAB PM3 Universal Device Programmer. It provides mechanical and electrical interface compatibility for programming 64-pin TQFP-packaged PICmicro® and dsPIC30F microcontrollers, supports ICSP™ connectivity, and enables high-reliability device programming in production or lab environments.

For engineers reviewing the AC164303 datasheet, AC164303 pinout, AC164303 application, or AC164303 equivalent, this socket module serves as a field-configurable, interchangeable hardware interface for programming Microchip 64-lead TQFP and SOIC devices on the MPLAB PM3 platform - critical for firmware validation, production programming, and device bring-up workflows.

Technical Context

The AC164303 socket module interfaces directly with the MPLAB PM3's 40-programmable-pin socket interface via a multi-pin connector, translating PM3's universal pin mapping to the specific 64-pin layout of target TQFP/SOIC devices. It supports In-Circuit Serial Programming (ICSP™) signals including PGD, PGC, VPP, VDD, and VSS across all supported packages.

No onboard logic or firmware resides in AC164303; it functions purely as a passive, precision-machined mechanical and electrical adapter. Compatibility is validated for Microchip's full line of 64-lead TQFP and SOIC-packaged PICmicro® and dsPIC30F devices listed in the MPLAB PM3 device support matrix.

FAQ

What is the AC164303 used for?

The AC164303 is a dedicated socket module that enables the MPLAB PM3 programmer to interface with 64-lead TQFP and SOIC-packaged Microchip PICmicro® and dsPIC30F microcontrollers. It provides precise mechanical alignment and reliable electrical contact during device programming, supporting both lab-based development and high-throughput production workflows using the AC164303 socket module.

Does the AC164303 include firmware or active circuitry?

No, the AC164303 contains no firmware, logic, or active components. It is a passive, precision-machined socket module that mechanically adapts the MPLAB PM3's 40-pin programmable interface to the 64-pin layout of TQFP and SOIC devices. All signal routing and timing control are handled by the MPLAB PM3 base unit, not the AC164303 socket module itself.

Is the AC164303 compatible with PROMATE II socket modules?

The AC164303 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 to be used with the MPLAB PM3 - the AC164303 itself is native to the PM3 platform and requires no adapter for operation.

Which Microchip devices are supported by the AC164303?

The AC164303 supports all Microchip PICmicro® and dsPIC30F microcontrollers housed in 64-lead TQFP or SOIC packages, as confirmed in the official MPLAB PM3 device support documentation. Specific part numbers must match the physical package type and pin count; the AC164303 does not support QFN, VQFN, or other non-TQFP/SOIC variants.

Can the AC164303 be used in standalone mode on the MPLAB PM3?

Yes, the AC164303 operates fully in all three MPLAB PM3 operating modes - PC Host, Standalone, and Safe - without modification or additional configuration. When installed in Standalone mode, the AC164303 socket module enables direct programming of compatible 64-lead TQFP/SOIC devices using the MPLAB PM3's front-panel controls and LCD interface.
