PIC32MX330F064LT-I/TL Übersicht
A 32-bit microcontroller (MCU) is a programmable system-on-chip that integrates a CPU core, volatile memory (SRAM), non-volatile program memory (Flash), and a configurable set of peripherals on a single die. Within the broader taxonomy, the PIC32MX3xx/4xx family sits between 8-bit PIC16/PIC18 parts and the higher-end PIC32MZ parts, offering 32-bit MIPS performance, USB, and DSP-class instructions at a cost closer to mid-range 16-bit MCUs. This positions PIC32MX330F064L as a mainstream workhorse for USB-connected embedded products.
Key features include 64 KB Flash (64K x 8), 16 KB RAM, 10-bit ADC, two I2S/SPI interfaces for audio codecs, Peripheral Pin Select (PPS) for remappable digital functions, a Parallel Master Port (PMP) for graphics or external bus interfaces, and a Charge Time Measurement Unit (CTMU) for capacitive touch and accurate time measurement. The integrated USB 2.0 full-speed OTG controller, DMA, and 5 V-tolerant I/O make the part especially attractive for connected devices that previously required an external PHY.
The PIC32MX330F064L silicon is built on a low-power CMOS process and runs from 2.3 V to 3.6 V. Architectural highlights include a 5-stage MIPS32 M4K pipeline, hardware multiply/divide, single-cycle MAC for DSP code, a deterministic interrupt controller, and Microchip's Harmony/PPS peripheral routing. Compared with 8-bit PIC MCUs at the same MHz, the M4K core provides roughly 6x the per-MHz performance, allowing existing firmware to be ported with significantly faster execution or lower clock rates.
Typical applications include USB HID / CDC peripherals, audio playback and recording via I2S, capacitive touch user interfaces using CTMU, low-cost HMI panels driven through PMP, and industrial sensor hubs that need USB-OTG plus DMA. It is also used in consumer electronics such as USB audio interfaces, e-readers, and small appliances that need a graphical display with a parallel interface.
When designing with this MCU, reserve a 1 uF plus 0.1 uF decoupling pair near each power pin, configure the JTAG/ICSP pins carefully to avoid contention, and use the PPS registers to remap peripherals rather than rewriting the PCB. USB-OTG designs must include the required 48 MHz clock accuracy and the correct bus pull-up topology.
This page synthesizes distributor pricing, drop-in PIC32 alternatives, and CTMU / USB-OTG design notes not found in the manufacturer datasheet alone, giving procurement and firmware engineers an at-a-glance reference for sourcing and second-source decisions.

Typische Anwendungen
PIC32MX330F064LT-I/TL ist geeignet für 6 Anwendungs: USB Audio Interface / USB DAC, Capacitive Touch User Interface, Industrial Sensor Hub with USB-OTG, Low-Cost Graphical HMI with PMP, USB-OTG Device / Gadget, Consumer USB Audio Dongle.
USB Audio Interface / USB DAC
The PIC32MX330F064LT-I/TL's integrated USB 2.0 full-speed OTG controller, dual I2S ports, 80 MHz MIPS32 M4K CPU (131 DMIPS), and DMA channels make it a strong fit for USB audio interfaces and external USB DACs. Up to 80 MHz CPU speed lets the MCU run USB isochronous transfers plus S/PDIF or I2S codec handshakes with low interrupt overhead. Using DMA for I2S sample flow keeps the CPU free for control-plane processing. Two I2S/SPI modules let designers connect both an ADC and DAC path for full-duplex audio.

Capacitive Touch User Interface
The Charge Time Measurement Unit (CTMU) plus 80 MHz MIPS throughput makes the PIC32MX330F064LT-I/TL well suited to drive mTouch capacitive touch panels and sliders. The CTMU allows accurate capacitance measurement without op-amps or external timing circuits, and the 16 KB SRAM holds touch scan buffers and gesture state machines. With Peripheral Pin Select (PPS), any digital I/O can be assigned to scan channels, simplifying PCB routing. Industrial temperature grade suits home appliance and industrial front-panel controls.

Industrial Sensor Hub with USB-OTG
The PIC32MX330F064LT-I/TL integrates 10-bit ADC, UART/USART, I2C, and LINbus plus USB-OTG in one chip, which simplifies industrial sensor hubs that stream data to a host PC or embedded gateway. Its 2.3 V to 3.6 V supply range lets it run from a single 3.3 V rail in factory automation environments. The DMA controller offloads sensor polling while the 80 MHz M4K core runs Modbus, LIN, or proprietary protocols. PPS allows flexible mapping of multiple UARTs and timers to a single PCB layout.
Empfohlen
Low-Cost Graphical HMI with PMP
The Parallel Master Port (PMP) peripheral and 64 KB Flash let the PIC32MX330F064LT-I/TL drive small graphical TFT or OLED displays for HMI panels. The PMP supports 8-bit and 16-bit parallel interfaces, freeing the CPU from bit-banging and allowing higher frame rates at 80 MHz. Combined with CTMU for touch input, the same MCU handles graphics and touch in cost-effective appliances.
Empfohlen
USB-OTG Device / Gadget
The integrated USB-OTG controller in the PIC32MX330F064LT-I/TL implements dual-role device/host operation, supporting CDC, HID, mass storage, and vendor classes. The 80 MHz CPU clock provides enough bandwidth for full-speed (12 Mbps) isochronous transfers without offloading work to an external companion chip. Microchip's MPLAB Harmony USB stack supports CDC, HID, MSD, and audio class drivers out of the box for this family.
Empfohlen
Consumer USB Audio Dongle
The PIC32MX330F064LT-I/TL's combination of USB-OTG, two I2S/SPI interfaces, DMA, and 16 KB SRAM enables small consumer USB audio dongles such as headset converters, or speaker-phone peripherals. Two I2S/SPI ports let the dongle interface with both an external codec for analog I/O and a digital amplifier for output. DMA offloads sample streaming at 48 kHz/16-bit, while the CPU handles HID controls and USB enumeration.

Designhinweise
Place a 1 uF bulk decoupling capacitor plus a 0.1 uF ceramic capacitor as close as possible to every VDDCORE and VDDIO pin pair. The PIC32MX330F064L datasheet specifies a 2.3 V to 3.6 V supply, and the exposed thermal pad must be soldered to a sufficient copper pour to keep junction within the -40 C to +85 C industrial range under sustained USB isochronous load. Estimated: at 80 MHz CPU + USB-OTG full-speed traffic, typical active current is on the order of 30 to 50 mA; design the 3.3 V regulator for at least 100 mA headroom.
Route the 48 MHz USB clock reference and D+/D- traces as a matched-length differential pair with 90 ohm impedance. Keep the USB connector's shield and chassis ground isolated from digital ground except at one bond point, and place the USB pull-up resistor (1.5 kohm to 3.3 V) within 4 mm of the D+ pin. The exposed thermal pad under the VTLA-124 must be soldered to a continuous ground pour with stitched thermal vias for heat dissipation.
Configure JTAG/ICSP pins (PGECx/PGEDx) carefully to avoid contention with peripheral functions in production firmware. Use Peripheral Pin Select (PPS) registers to remap peripherals rather than rewiring the PCB. The CTMU requires firmware calibration per chip and per pin to compensate for parasitic capacitance - do not assume raw CTMU counts are absolute without calibration.
USB-OTG full-speed signaling requires the 48 MHz clock reference to meet +/- 2.5 percent accuracy over temperature; use an external crystal or MEMS oscillator rather than the internal FRC for USB isochronous endpoints. Keep high-speed digital traces away from the analog AVSS/AVDD rails feeding the 10-bit ADC. Decouple AVdd with a 10 uF plus 0.1 uF pair to prevent ADC sample contamination.
Compliance-Informationen
RoHS and REACH compliant per Microchip product page. Industrial -I grade only - not AEC-Q100 qualified; use PIC32MX330F064LT-V/TL for automotive. Halogen-free status not explicitly stated in verified data.
