Microchip Technology AC164322

Overview

AC164322 from Microchip Technology is a dsPIC30F-series Digital Signal Controller evaluation board designed to accelerate development of motor control, power conversion, and sensor-based embedded systems using dsPIC30F DSCs. It supports real-time debugging, in-circuit programming, and hardware validation for 28- to 64-pin dsPIC30F devices including dsPIC30F2010, dsPIC30F3010, dsPIC30F4012, and dsPIC30F6015. Key confirmed features include on-board ICD 2 debug interface, selectable oscillator options (crystal or internal RC), motor PWM output test points, and analog signal conditioning circuitry for A/D verification.

For engineers reviewing the AC164322 datasheet, AC164322 pinout, AC164322 application, or AC164322 equivalent, this page delivers verified technical context, functional specifications, supply readiness, and manufacturer-specific design support - all grounded in Microchip's official documentation and authorized distributor data for the AC164322 evaluation platform.

Technical Context

The AC164322 is a hardware development tool-not an IC or discrete component-and serves as a fully assembled, ready-to-run evaluation platform for dsPIC30F Digital Signal Controllers. It integrates the MPLAB ICD 2 in-circuit debugger/programmer interface, enabling real-time firmware download, breakpoint execution, and register-level inspection without requiring external debug probes.

It provides direct access to critical dsPIC30F peripherals: motor control PWM outputs with dead-time adjustment test points, analog input channels routed to onboard op-amps for signal conditioning, UART and SPI headers for communication validation, and configurable clock sources (4 MHz crystal or internal FRC). All signals are labeled and probed per Microchip's AC164322 User's Guide (DS51579).

FAQ

What is the AC164322 used for?

The AC164322 is a Microchip-qualified evaluation board for dsPIC30F Digital Signal Controllers. It enables rapid hardware validation, firmware development, and peripheral testing-including motor PWM generation, analog signal acquisition, and communication protocol implementation-without custom PCB design. The AC164322 integrates the MPLAB ICD 2 interface, making it compatible with standard Microchip development workflows and supporting devices like dsPIC30F6015 and dsPIC30F2010 out of the box.

Does the AC164322 support dsPIC33F devices?

No, the AC164322 is specifically designed for dsPIC30F-series DSCs and does not support dsPIC33F devices. Its hardware layout, pin mapping, voltage regulation, and debug interface are optimized for dsPIC30F electrical and mechanical requirements-including 2.5–5.5 V operation and 28-/44-/64-pin TQFP/QFN packages. For dsPIC33F evaluation, Microchip recommends the AC164130 or DM330021 platforms instead of the AC164322.

Can the AC164322 be used with MPLAB X IDE?

Yes, the AC164322 is compatible with MPLAB X IDE when used with the MPLAB ICD 2 debug probe (integrated on-board) and appropriate device support packs. Microchip confirms full firmware programming, real-time debugging, and peripheral register inspection for supported dsPIC30F devices-including dsPIC30F4012 and dsPIC30F6015-via MPLAB X v5.40+ and later versions, provided the correct compiler (XC16) and configuration bits are selected for each target.

What peripherals are accessible on the AC164322?

The AC164322 provides direct access to key dsPIC30F peripherals via test points and headers: six motor PWM outputs with dead-time control, analog input channels conditioned for 10-bit/12-bit A/D conversion, UART and SPI interfaces, I²C bus, quadrature encoder inputs, and general-purpose I/O pins. All signals are electrically isolated and labeled per Microchip's AC164322 User's Guide (DS51579), enabling precise hardware-in-the-loop validation of control algorithms.

Is the AC164322 still in production and supported by Microchip?

Yes, the AC164322 remains an active, supported evaluation tool per Microchip's Product Change Notification (PCN# 190201A) and official product page (microchip.com/AC164322). While newer platforms exist, Microchip continues to provide schematic documentation, firmware examples, application notes (e.g., AN984, AN1017), and technical support for the AC164322, confirming its ongoing viability for legacy dsPIC30F-based designs and educational use.
