Product details
Overview
AC164321 from Microchip Technology is a dsPIC30F-series 16-bit digital signal controller featuring 30 MIPS performance, 2.5–5.5V operation, self-write Flash memory, and integrated motor control PWM peripherals. It includes up to 16-channel 10-bit A/D conversion at 1000 ksps, dual UARTs, two SPI™ interfaces, and CAN 2.0B support - deployed in brushless DC motor drives and power factor correction circuits.
For engineers reviewing the AC164321 datasheet, AC164321 pinout, AC164321 application, or AC164321 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use scenarios, and two confirmed alternative DSCs for migration or second-sourcing decisions.
Technical Context
The AC164321 implements a modified Harvard architecture with separate program and data buses, enabling single-cycle instruction execution at 30 MIPS. Its core integrates a 17×17 hardware multiplier and barrel shifter for efficient DSP math, supporting both C-optimized and assembly-level motor control algorithms.
It features dual 16-bit motor control PWM modules with dead-time insertion, quadrature encoder interface, and high-resolution capture/compare units - all synchronized to a shared timebase for precise phase-aligned switching in three-phase inverters.

FAQ
What is the maximum operating frequency of the AC164321?
The AC164321 operates at a maximum instruction rate of 30 MIPS, achieved with an internal PLL that multiplies the input oscillator frequency. Its core runs at 60 MHz internal clock (Fcy = 30 MHz), supporting deterministic interrupt latency down to 6 instruction cycles - critical for sub-microsecond PWM update timing in AC164321-based motor control systems.
Does AC164321 support CAN communication?
Yes, AC164321 integrates a full CAN 2.0B controller with transmit/receive buffers, message filtering, and automatic retransmission. It supports bit rates up to 1 Mbps and is used in automotive body control modules and industrial automation networks where AC164321 serves as a node controller interfacing with CAN bus sensors and actuators.
What development tools are compatible with AC164321?
AC164321 is fully supported by Microchip's MPLAB® X IDE, MPLAB C30 compiler, and MPLAB ICD 3 debugger. Hardware tools include the dsPICDEM™ MCHV-2 development board and the Explorer 16 platform - all validated for AC164321 firmware bring-up, real-time debugging, and motor control algorithm tuning.
Is AC164321 pin-compatible with other dsPIC30F devices?
No, AC164321 uses an 80-pin TQFP package (80PT) unique to the dsPIC30F60xx series. While it shares peripheral register mapping and instruction set compatibility with dsPIC30F6010/6010A/6012/6012A, physical pinout differs from 64-pin or 44-pin variants - requiring dedicated PCB layout for AC164321.
What is the Flash endurance specification for AC164321?
AC164321 specifies 10,000 erase/write cycles for its self-write Flash memory, with data retention guaranteed for 20 years at +85°C. This enables reliable field firmware updates and parameter storage in AC164321-based industrial controllers where configuration persistence and over-the-air upgrades are required.
