PIC32MX330F064L-I/PT 概要
A 32-bit microcontroller (MCU) is a single-chip processor that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals such as timers, communication interfaces, and analog blocks. PIC32MX devices occupy the mid-range of the PIC32 family, sitting between low-cost PIC32MX1/2/3/4/5/6/7 entry-level devices and higher-end PIC32MZ parts. They are widely used as upgrade paths from 16-bit PIC24/dsPIC designs because they share peripheral libraries and pin-compatibility with many 16-bit DIP/PT packages, allowing migration without PCB rework.
Key features of the PIC32MX330F064L include 10-bit ADC with up to 1 Msps conversion rate, multiple UART/SPI/I2C interfaces, and MIPS16e code compression for up to 40% smaller code size. The device operates from 2.3 V to 3.6 V across the industrial -40C to +105C temperature range, supports low-power Idle and Sleep modes, and offers a 5-channel DMA controller for offloading CPU data movement. The 100-TQFP package provides generous I/O count for applications needing parallel buses, multiple serial interfaces, and USB connectivity simultaneously.
Typical applications include industrial control panels, USB audio devices, motor control front-ends, barcode scanners, point-of-sale terminals, and graphical display controllers. The CTMU enables touch sensing and capacitive measurement, while the PMP simplifies interfacing to graphical LCDs and external parallel peripherals such as FIFO memories and ASICs. Engineers migrating from PIC24FJ/PIC24H designs often select this part for its familiar development ecosystem (MPLAB X IDE, XC32 compiler, Harmony framework).
When designing with this part, place decoupling capacitors (100 nF + 10 uF bulk) as close as possible to every VDD/VSS pair, route the 48 MHz crystal traces symmetrically with ground guard rings, and verify USB-OTG board impedance (90 ohm differential) against the USB 2.0 specification. The PPS feature must be configured early in firmware to remap peripheral functions to physical pins, otherwise code will run but peripherals will be inactive.
This page synthesizes distributor pricing, same-brand drop-in alternatives drawn from the PIC32MX3/4/5/6/7 family, and practical design notes not found in the standalone datasheet, helping procurement and firmware engineers evaluate this part efficiently.

主な用途
PIC32MX330F064L-I/PT の用途: 6 件s: USB Audio Class Devices, Industrial HMI Touch Panels, USB Barcode Scanners, Point-of-Sale Terminals, Motor Control Front-Ends, Data Loggers with USB Connectivity.
USB Audio Class Devices
The PIC32MX330F064L-I/PT is well suited for USB audio class 1.0 devices such as USB headphones, USB microphones, and USB DACs. Its 80 MHz MIPS32 M4K core delivers sufficient processing headroom for 24-bit/96 kHz audio streaming at full USB bandwidth, while the integrated USB 2.0 Full-Speed OTG controller and two I2S interfaces allow direct connection to external audio codecs (e.g., Microchip LAN9500A, Cirrus CS43L22) without an external PHY. The 16 KB SRAM holds USB audio descriptors plus 4-5 ms of audio buffering, and the CTMU can be used for touch-button volume controls on the device housing. Engineers should allocate at least 32 KB Flash for the USB stack plus Harmony framework drivers, leaving roughly 30 KB for application logic.
おすすめ
Industrial HMI Touch Panels
The PIC32MX330F064L-I/PT integrates a Charge Time Measurement Unit (CTMU) and Parallel Master Port (PMP), making it ideal for industrial HMI touch panels with capacitive buttons or sliders. The CTMU combined with the 10-bit ADC enables reliable capacitive touch sensing for up to 16 buttons with sub-1 mm positional accuracy, while the PMP directly drives 4.3-inch or 5-inch TFT LCDs at WQVGA (480x272) resolution without an external graphics controller. The 80 MHz core can refresh full-screen graphics at 30+ Hz while simultaneously polling USB host mode for firmware updates. The industrial -40 C to +105 C temperature range allows deployment in factory-floor enclosures without thermal derating.
おすすめ
USB Barcode Scanners
Handheld and fixed-mount USB barcode scanners benefit from the PIC32MX330F064L-I/PT's combination of USB HID device support, fast 80 MHz core, and 64 KB Flash. The integrated USB Full-Speed controller enumerates as an HID Keyboard or HID POS Scanner device without external firmware-side drivers, while the MIPS32 M4K core can decode 1D/2D barcode symbologies (Code128, QR, DataMatrix) from camera sensors over the parallel PMP or SPI interfaces within 50-100 ms per frame. The 16 KB SRAM buffers decoded payloads and image preprocessing intermediate state. Low-power Sleep mode (under 1 mA) extends battery life in portable scanner applications.
おすすめ
Point-of-Sale Terminals
POS terminals rely on the PIC32MX330F064L-I/PT to integrate USB host and device modes simultaneously for connecting to printers, cash drawers, customer displays, and payment PIN pads. The USB-OTG controller supports dual-role operation, allowing the same port to act as a device when connected to a host PC (for configuration) or as a host when driving peripherals. The 5-channel DMA controller offloads data movement between UART (for cash drawer kick-out), SPI (for NFC reader), and I2C (for secure authentication), leaving the CPU free for transaction processing. The industrial temperature range ensures reliable operation in retail environments.
おすすめ
Motor Control Front-Ends
The PIC32MX330F064L-I/PT can serve as a motor-control front-end for small BLDC and stepper motors in appliances and industrial equipment. The Output Compare and PWM modules generate up to six channels of complementary PWM at 80 MHz resolution, suitable for 20 kHz switching frequency motor drive. The 10-bit ADC samples phase currents at 1 Msps for FOC (field-oriented control) with 10 kHz control loop bandwidth, while the CTMU provides BEMF (back-EMF) timing measurements during zero-cross detection. The PMP can drive external gate drivers directly. For more demanding multi-axis motor control, the PIC32MK or dsPIC33 families are recommended.
おすすめ
Data Loggers with USB Connectivity
Portable and industrial data loggers use the PIC32MX330F064L-I/PT to record sensor measurements to external SPI Flash or microSD cards via the PMP, and to offload data via USB MSD class. The 64 KB Flash holds filesystem libraries (FatFs, LittleFS) plus logging firmware, while the 16 KB SRAM buffers sectors during card write operations. The 5-channel DMA streams ADC samples directly to memory without CPU intervention, enabling continuous multi-channel logging at up to 100 kHz aggregate sample rate. The USB-OTG controller enumerates as a Mass Storage Device when connected to a PC, presenting the SD card as a removable drive for easy file retrieval without custom drivers.

設計ノート
The PIC32MX330F064L-I/PT requires decoupling on every VDD/VSS pin pair. Place a 100 nF ceramic (X7R) capacitor within 3 mm of each VDD pin, and add a single 10 uF tantalum or ceramic bulk capacitor near the device. For USB applications, add a 4.7 uF capacitor on the VUSB pin. Avoid routing high-speed digital signals (USB, oscillator) directly over the analog AVSS/AVDD plane if a separate analog supply is used, to prevent digital noise from coupling into ADC readings.
Route the 48 MHz USB clock traces with 90 ohm differential impedance, keeping D+ and D- matched within 1 mm. Place the crystal within 5 mm of the OSC1/OSC2 pins, with a ground guard ring around both traces to prevent noise injection. The ICSP programming pins (PGEC2/PGED2 or PGEC3/PGED3) must be brought out to a header or test pad even if not used in production, for in-field firmware updates. Keep the MCLR pin trace short and add a 10 kohm pull-up to VDD as recommended by the manufacturer datasheet.
A common mistake is forgetting to configure the Peripheral Pin Select (PPS) registers in firmware. On reset, all PPS-mapped peripherals are disconnected from physical pins, so UART/SPI/I2C code will compile and start but produce no signals on the scope. Always call the PPS initialization early in main(). Another pitfall is exceeding 3.6 V on any I/O pin when the device is unpowered, which can cause latch-up via the ESD protection diodes. Ensure no external signals drive the MCU while VDD is below 2.0 V.
コンプライアンス情報
RoHS compliant per Microchip product page. Not AEC-Q100 qualified - the 330 family targets industrial/consumer, not automotive. Use PIC32 variants with -V or -E suffixes for extended temperature ranges if needed.
