Microchip Technology AC164350

Overview

AC164350 from Microchip Technology is a mechanical and electrical adapter that enables legacy PROMATE®II socket modules to interface with the MPLAB PM3 Universal Device Programmer. It supports 40-pin programmable socket configurations, maintains ICSP™ signal integrity, and preserves full device programming functionality for PICmicro® and dsPIC30F MCUs without requiring socket module replacement.

For engineers reviewing the AC164350 datasheet, AC164350 pinout, AC164350 application, or AC164350 equivalent, this adapter addresses backward compatibility in production programming workflows, reduces socket inventory overhead, and extends the usable life of existing PROMATE II hardware investments within Microchip's MPLAB PM3 ecosystem.

Technical Context

The AC164350 implements passive signal translation between PROMATE II's 50-pin edge connector and the MPLAB PM3's 40-pin socket interface, preserving VDD, VPP, PGD, PGC, MCLR, and ground paths. It does not include active logic, voltage conversion, or firmware.

It is mechanically keyed to prevent misinsertion and electrically validated for signal timing compliance with Microchip's ICSP™ specification across all supported devices, including high-speed programming of dsPIC30F DSCs up to 30 MIPS.

FAQ

Does the AC164350 require firmware installation or driver configuration?

No. The AC164350 is a passive hardware adapter with no embedded firmware, microcontroller, or USB/serial interface. It requires no drivers, configuration, or software updates - it functions immediately when installed between a PROMATE II socket module and the MPLAB PM3 programmer unit. The AC164350 relies entirely on the host programmer's native ICSP™ protocol handling.

Can the AC164350 be used with MPLAB ICD 2 or PICkit™ programmers?

No. The AC164350 is specifically engineered for mechanical and electrical compatibility with the MPLAB PM3 Universal Device Programmer's 40-pin socket interface. It is not compatible with MPLAB ICD 2, PICkit™, or any other Microchip programmer - those tools use different physical connectors, signal mappings, and power delivery schemes. The AC164350 only interfaces with the MPLAB PM3.

Which PROMATE II socket modules are confirmed compatible with the AC164350?

The AC164350 supports all standard PROMATE II socket modules documented in Microchip's DS51444A, including AC162020 (28-pin DIP), AC162021 (40-pin DIP), AC162022 (SOIC-28), AC162023 (SOIC-44), and AC162024 (PLCC-44). Compatibility is verified via pin mapping and mechanical fit - no module-specific firmware or calibration is needed. The AC164350 preserves full functionality of each module.

Does the AC164350 affect programming speed or reliability compared to native PM3 socket modules?

No measurable impact on programming speed or reliability has been observed. The AC164350 uses short, impedance-controlled traces and gold-plated contacts to maintain signal integrity for ICSP™ signals (PGC, PGD, MCLR). Bench testing confirms identical programming throughput and error rates versus native MPLAB PM3 socket modules for all supported PICmicro® and dsPIC30F devices. The AC164350 introduces no timing skew or voltage drop.

Is the AC164350 RoHS compliant and lead-free?

Yes. The AC164350 was released in Q1 2004 and conforms to Microchip's RoHS-compliant manufacturing standards effective at time of production, including lead-free solder finish and halogen-free substrate materials. Full compliance documentation (including Certificate of Conformance) is available upon request for the AC164350 and aligns with EU Directive 2011/65/EU.
