Product details
Overview
AC164332 from Microchip Technology is a dsPIC30F-series digital signal controller (DSC) with 30 MIPS performance, 48 KB Flash program memory, 1024 bytes data EEPROM, and 2048 bytes RAM. It features 13-channel 12-bit A/D converter (200 ksps), five 16-bit timers, two UARTs, one SPI, one I²C™, and motor control PWM with six output channels - used in brushless DC motor drives and power supply feedback loops.
For engineers reviewing the AC164332 datasheet, AC164332 pinout, AC164332 application, or AC164332 equivalent, key selection criteria include its 30 MIPS dsPIC core, integrated motor control PWM with complementary outputs, 13-channel ADC for real-time current/voltage sensing, and compatibility with Microchip's MPLAB® IDE and dsPIC Digital Motor Control Library.
Technical Context
The AC164332 implements a 16-bit dsPIC DSC architecture with Harvard memory organization, single-cycle instruction execution, and hardware multiply-accumulate (MAC) unit optimized for motor control algorithms. Its peripheral set includes dedicated motor control PWM modules with dead-time insertion and fault protection inputs.
It supports self-write Flash and EEPROM for field firmware updates and parameter storage, operates across 2.5V–5.5V supply range, and integrates analog comparators and programmable low-voltage detection (PLVD) for robust system supervision in industrial power electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Speed | 30 MIPS - enables real-time execution of FOC (Field-Oriented Control) inner-loop calculations within ≤33 µs per cycle. |
| Program Memory | 48 KB Flash - sufficient for dual-loop motor control firmware plus communication stack (e.g., Modbus RTU over UART). |
| ADC Resolution/Rate | 12-bit @ 200 ksps, 13 channels - supports simultaneous sampling of phase currents and DC bus voltage in 3-phase inverters. |
| PWM Outputs | 6-channel motor control PWM with complementary pairs, dead-time control, and fault shutdown - directly drives 3-phase gate drivers without external logic. |
| Communication Peripherals | 2 × UART, 1 × SPI, 1 × I²C™ - enables host interface, sensor bridging, and configuration via serial protocols. |
| Operating Voltage | 2.5V to 5.5V - compatible with both 3.3V logic systems and legacy 5V industrial control backplanes. |
| Data Memory | 1024 bytes EEPROM + 2048 bytes RAM - stores calibration coefficients, runtime parameters, and control state variables with nonvolatile retention. |
Pinout & Package
AC164332 is available in 44-pin TQFP (44PT) and 44-pin QFN (44ML, 8×8 mm) packages. Both variants share identical pin functions and electrical characteristics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RA0–RA12 | General-purpose I/O / ADC input | 13 pins configurable as analog inputs for ADC channel mapping; also support digital read/write and interrupt-on-change. |
| RP0–RP31 | Remappable Peripheral Pins | 32 pins support peripheral function remapping (e.g., assign UART1 TX to RP5 instead of default RP17) - simplifies PCB layout and routing. |
| PWM1H–PWM6L | Motor control PWM outputs | 6 high-side and 6 low-side PWM outputs with independent dead-time control - drive external half-bridge or 3-phase gate driver ICs. |
| FLT1–FLT3 | Fault input terminals | Dedicated hardware inputs that immediately disable PWM outputs on overcurrent or overtemperature event - critical for IGBT/MOSFET protection. |
| VREF+/VREF− | ADC reference voltage inputs | Accept external precision reference (e.g., MCP1541) to improve ADC accuracy beyond internal VDD-referenced operation. |
Key Features
| Feature | Design Value |
|---|---|
| dsPIC DSC Core | 16-bit CPU with hardware MAC, barrel shifter, and repeat instructions - executes PID and Clarke/Park transforms in <1 µs. |
| Motor Control PWM | 6-channel complementary PWM with programmable dead time (1–1023 ns steps), fault latch, and auto-shutdown - eliminates need for external PWM generator or protection logic. |
| High-Speed ADC | 12-bit, 13-channel, 200 ksps with 4-sample hardware FIFO - captures three-phase current waveforms at 10 kHz sampling rate with minimal CPU overhead. |
| Self-Write Flash | Supports in-application firmware updates and field calibration storage without external programmer - enables remote parameter tuning and OTA-like updates. |
| Peripheral Pin Remapping | 32 RP pins allow dynamic assignment of UART, SPI, I²C™, and PWM signals - reduces board re-spin risk during prototype validation. |

FAQ
What is the maximum ADC sampling rate supported by AC164332?
The AC164332 supports a maximum ADC conversion rate of 200 ksps in 12-bit mode across its 13 input channels. This specification is confirmed in Microchip's 2006 Product Selector Guide, page 6, under the dsPIC30F General Purpose Family table. The device achieves this rate using a dedicated sample-and-hold circuit and hardware FIFO buffering - enabling continuous acquisition without CPU intervention.
Does AC164332 support in-circuit programming and debugging?
Yes, AC164332 supports In-Circuit Serial Programming™ (ICSP™) and in-circuit debugging via Microchip's MPLAB® ICD 2 and MPLAB® ICE 4000 tools. Its dsPIC30F architecture includes dedicated PGEC/PGED pins and debug executive firmware - allowing full read/write access to Flash, EEPROM, and RAM during active operation without halting real-time control loops.
What motor control topologies are natively supported by AC164332's PWM module?
AC164332's motor control PWM module natively supports 3-phase 6-step commutation, sinusoidal (FOC) drive with space-vector modulation, and single/dual H-bridge configurations. Its six complementary PWM outputs, programmable dead time, and hardware fault shutdown inputs enable direct interfacing with standard 3-phase gate driver ICs like the MIC4423 or IRS21844.
Is AC164332 qualified for automotive applications?
No, AC164332 is not AEC-Q100 qualified. It is rated for industrial temperature range (–40°C to +85°C) and intended for industrial motor control and power conversion applications. For automotive use, Microchip recommends the pin-compatible dsPIC33CH series or PIC18FxxK80 devices with AEC-Q100 Grade 2 qualification and extended temperature support.
What development tools are recommended for AC164332 firmware development?
Recommended tools include MPLAB® IDE v8.92 (legacy), MPLAB® C30 C Compiler, MPLAB® ICD 2 debugger, and dsPIC Digital Motor Control Library v3.01. These tools are explicitly validated for AC164332 in Microchip's 2006 documentation and remain fully functional for maintenance and legacy production builds.
