Product details
Overview
AC164339 from Microchip Technology is a universal SOIC socket module designed for programming dsPIC33FJ06GS101-SO microcontrollers on the MPLAB PM3 programmer. It features an 18-pin SOIC footprint, supports PVDD voltage routing to DUT pin 18 (VDD), and enables high-current programming mode entry for devices requiring elevated Idd during programming startup.
For engineers reviewing the AC164339 datasheet, AC164339 pinout, AC164339 application, or AC164339 equivalent, this module addresses current-limiting issues in MPLAB PM3 systems when programming dsPIC33FJ06GS101-SO devices - particularly with assembly #10-00359 - and requires physical modification to route PVDD directly to VDD.
Technical Context
The AC164339 socket module interfaces between the MPLAB PM3 programmer's 28-pin SOIC socket and 18-pin SOIC target devices like the dsPIC33FJ06GS101-SO. Its mechanical layout positions the 18-pin DUT top-justified within the 28-pin socket, mapping DUT pin 18 to socket pin 28.
It provides dedicated signal routing for PGD, PGC, VPP, VSS, and VDD lines, but its native PVDD path through PM3 drivers is insufficient for the dsPIC33FJ06GS101-SO's programming-mode Idd surge. The module is modifiable via wire-wrap to bypass driver-limited PVDD and deliver high-current PVDD directly to DUT VDD (pin 18).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Package Type | 18-pin SOIC socket module - physically mates with 18P-SOIC devices including dsPIC33FJ06GS101-SO. |
| DUT Pin Mapping | DUT pin 18 (VDD) maps to socket pin 28 - enabling direct high-current PVDD connection post-modification. |
| Compatible Programmer | MPLAB PM3 with assembly #10-00359 - only verified for this revision due to driver current limitations. |
| Target Device | dsPIC33FJ06GS101-SO - specifically validated for programming-mode Idd surge mitigation via AC164339 modification. |
| Modification Requirement | Wire-wrap modification required to route PVDD from P2 connector pin 2 to DUT VDD (pin 18) - no firmware or software change needed. |

FAQ
What is the primary function of the AC164339 socket module?
The AC164339 socket module serves as a mechanical and electrical interface between the MPLAB PM3 programmer and 18-pin SOIC microcontrollers such as the dsPIC33FJ06GS101-SO. Its design enables physical mounting and signal routing - notably requiring modification to deliver sufficient PVDD current for reliable programming mode entry of that specific device.
Which dsPIC device is explicitly validated for use with AC164339?
The dsPIC33FJ06GS101-SO is the only device explicitly validated in Microchip's Engineering Technical Note ETN #31 for use with the AC164339 socket module. The note documents the "Fail to Read Device ID" issue and confirms the AC164339 modification resolves it for this exact part number under specified PM3 assembly conditions.
Why does AC164339 require a hardware modification for dsPIC33FJ06GS101-SO programming?
The AC164339 requires modification because the dsPIC33FJ06GS101-SO draws high current (Idd) during programming mode entry - exceeding the current capability of the MPLAB PM3's internal drivers. The AC164339 modification routes PVDD directly from the P2 connector to DUT pin 18 (VDD), bypassing those current-limited drivers and restoring reliable programming.
Is AC164339 compatible with other MPLAB programmers besides PM3?
No official compatibility is documented for AC164339 with programmers other than the MPLAB PM3 - specifically assembly #10-00359. Microchip's ETN #31 identifies the issue and solution exclusively in the context of the PM3 platform, and no validation data exists for PICkit, ICD, or Snap programmers.
What is the correct pin mapping between AC164339 and dsPIC33FJ06GS101-SO?
In the AC164339 socket module, the dsPIC33FJ06GS101-SO is mounted top-justified in the 28-pin socket, resulting in DUT pin 18 (VDD) aligning with socket pin 28. This mapping is critical for the ETN #31 modification, which connects P2 pin 2 (PVDD source) to socket pin 28 to power DUT VDD directly.
