PIC32MX330F064LT-I/PT 概要
A microcontroller (MCU) is an integrated circuit that combines a CPU core, non-volatile program memory (typically Flash), working RAM, and a rich set of on-chip peripherals such as timers, communication controllers, and analog blocks. The PIC32MX3/4 family sits in Microchip's PIC32 portfolio as an entry-to-mid-range 32-bit line, bridging the gap between 8-bit PIC16/PIC18 designs and high-performance Cortex-M alternatives. Within this taxonomy, PIC32MX330F064L is a code- and pin-compatible member of the PIC32MX3x0 sub-family, alongside parts like PIC32MX340 and PIC32MX350.
Key features include 64 KB single-cycle Flash with prefetch, 16 KB SRAM, 80 MHz / 1.56 DMIPS per MHz performance, and full-speed USB-OTG with on-chip transceiver. The device supports 2.3V to 3.6V single-supply operation, a 10-bit 1 Msps ADC with up to 28 analog inputs, and Microchip's standard MIPS-based Harmony/MPLAB development ecosystem with FreeRTOS support.
Architecturally, the chip combines a 5-stage MIPS M4K pipeline with dual I/O ports, a DMA controller, and parallel master port (PMP). Compared to PIC32MX1/2 series it adds higher pin count and CTMU, while keeping peripheral compatibility so firmware is portable across the family.
Typical applications include USB peripherals, industrial control panels, consumer audio (USB speakers, headsets), HMI displays, sensor hubs, and motor control front-ends. The combination of USB-OTG, ample analog channels, and 80 MHz headroom suits compact low-power designs.
When designing with this part, route the 12 MHz crystal traces symmetrically with short traces and a ground guard ring; place the VUSB capacitor and ferrite per the USB section of the family reference manual to meet USB-OTG compliance.

主な用途
PIC32MX330F064LT-I/PT の用途: 6 件s: USB-OTG Peripherals (Speakers / HID), Industrial Control Panels and HMI, Consumer Audio Devices (USB Headsets), Sensor Hubs and Data Loggers, Home Automation Gateways, Motor Control Front-Ends (BLDC / Stepper).
USB-OTG Peripherals (Speakers / HID)
The PIC32MX330F064LT-I/PT integrates a full-speed USB-OTG controller with on-chip transceiver and internal pull-up/pull-down resistors, so only an external VUSB capacitor, ferrite, and D+/D- resistors are required to meet USB compliance. At 80 MHz the M4K core handles USB audio class 1.0 streaming at 48 kHz/16-bit with headroom for HID control and DSP. 16 KB of SRAM accommodates double-buffered audio packets plus the Harmony USB stack.
おすすめ
Industrial Control Panels and HMI
The PIC32MX330F064LT-I/PT's combination of 80 MHz core, 10-bit ADC with up to 28 analog channels, five UARTs, and a parallel master port makes it well-suited for industrial HMI front-ends driving character or small TFT displays. The CTMU peripheral simplifies capacitive touch-button scanning, eliminating an external touch controller. The -40 to +85 C industrial temperature grade suits factory-floor enclosures.
おすすめ
Consumer Audio Devices (USB Headsets)
The PIC32MX330F064LT-I/PT supports USB audio class 1.0 at 48 kHz with on-chip 10-bit DAC optional (via PWM mode) and I2S interfaces for external audio codecs. Its DMA controller offloads I2S sample streaming, leaving the MIPS core free for volume / EQ processing. The Harmony audio framework provides ready-made USB speaker and headphone drivers that compile directly against this device.
おすすめ
Sensor Hubs and Data Loggers
With 28 ADC channels, 5 UARTs, 2 I2C, 2 SPI/I2S, and a DMA controller, the PIC32MX330F064LT-I/PT acts as a multi-protocol sensor hub consolidating data from UART GPS, I2C sensors, and SPI IMUs into a single logging pipeline. The 16 KB SRAM is adequate for circular buffers covering several seconds of multi-sensor data, and the 64 KB Flash stores the Microchip Harmony TCP/IP lite stack plus application code.
おすすめ
Home Automation Gateways
The PIC32MX330F064LT-I/PT is well matched to sub-gateway roles in home automation: it bridges UART-based RF modules (Zigbee, LoRa), Wi-Fi modules over UART, and Bluetooth over HCI. USB-OTG enables a fallback for cellular modems or USB dongles. The 80 MHz core and 64 KB Flash run the Harmony TCP/IP lite stack for local web UI, OTA update, and MQTT-bridge functions.
おすすめ
Motor Control Front-Ends (BLDC / Stepper)
The PIC32MX330F064LT-I/PT's 5 PWM outputs, QEI interfaces, and 1 Msps ADC make it a competent front-end for low-power BLDC or stepper drives under 200 W. Microchip's MPLAB Harmony motor-control framework provides FOC, trapezoidal, and sensorless commutation libraries targeting this device. The CTMU can additionally time back-EMF events for sensorless commutation.

設計ノート
Route the 12 MHz primary oscillator traces symmetrically and as short as possible, with a continuous ground guard ring and grounded copper pour on the layers beneath. Keep the crystal within 5 mm of the OSC1/OSC2 pins and avoid routing high-speed signals (USB D+/D-, SPI clocks) within 3 mm of the crystal traces to minimize jitter and stray pickup. Place the two crystal load capacitors as close as possible to the OSC pins and connect the other end directly to the ground guard ring.
Place a 10 uF bulk capacitor and a 0.1 uF decoupling cap adjacent to each VDD/AVDD pair. The USB-OTG VUSB pin requires a 1 uF low-ESR ceramic to the local ground, and a ferrite bead on the VBUS line per the USB section of the PIC32MX3/4 Family Reference Manual. Ensure AVDD tracks VDD within 0.3 V; otherwise ADC accuracy degrades. Estimated: the typical 80 MHz active current is approximately 30 mA from VDD, so a 3.3 V LDO rated at least 100 mA (e.g., MCP1700) provides comfortable margin.
Do not leave the MCLR pin floating - tie it to VDD through a 10 kohm pull-up and a 100 nF capacitor to ground for proper reset. Configure all unused I/O pins as digital outputs driving low to minimize power consumption and reduce noise injection into analog inputs. Verify the device ID using the DEVSN0/DEVCFG0 registers in your bootloader to prevent accidentally programming the wrong PIC32 variant during field upgrades.
For USB-OTG full-speed signaling, route the D+ and D- traces as a 90 ohm differential pair with matched length within 150 mil and no splits. Keep the pair reference over a continuous ground plane and place a common-mode choke near the connector. Test with USB-IF compliance tools; we recommend a USB-IF certified hub as a sanity check before field deployment.
