PIC32MX330F064LT-V/PF Overview
What is a PIC32MX3xx microcontroller? The PIC32MX3/4 family from Microchip combines a 32-bit MIPS M4K core with integrated peripherals such as USB-OTG, CAN, CTMU, and up to two I2S/SPI interfaces at low cost. It belongs to the hierarchy microcontroller -> embedded MCU -> RISC processor -> semiconductor IC, making it suitable for connected and real-time embedded designs that outgrow 8-bit or 16-bit parts.
Key features of the PIC32MX330F064LT-V/PF include 80MHz / 100MHz (PF speed grade) operation, 64KB Flash program memory, 16KB SRAM, 5 channels of 10-bit ADC, two I2C, two SPI/I2S, USB-OTG, CAN, CTMU, RTCC, PMP, and four 16-bit timers. The 100-pin TQFP package exposes up to 85 I/O pins.
Architecturally, the device uses a single-cycle hardware multiply and divide unit, 5-stage pipeline, and MIPS32 release-2 instruction set. The 64KB Flash is split into boot + general Flash regions and supports run-time self-programming under firmware control.
Typical applications include automotive body and HVAC modules, industrial HMI and motor control front-ends, USB peripherals, CAN node endpoints, low-cost graphics, and audio bridges using the on-chip I2S ports.
Design consideration: AEC-Q100 Grade 2 compliance and the wider -40C to +105C operating range make this part well suited to automotive clusters and under-hood peripherals that would otherwise need industrial-only MCUs.

Typical Applications
PIC32MX330F064LT-V/PF is suitable for 6 applications: Automotive Body Control Module, Industrial HMI / Touch Panel, USB Peripheral / Data Logger, Audio Bridge with I2S, CAN Node Endpoint, Motor Control Front-End.
Automotive Body Control Module
PIC32MX330F064LT-V/PF fits automotive body controllers thanks to AEC-Q100 Grade 2 qualification and the -40C to +105C operating range. The 80MHz MIPS32 M4K core delivers 100 MIPS, enough to drive CAN/LIN body networks and PWM-driven loads. With two SPI/I2S ports, USB-OTG, and CAN, it integrates gateway functions that previously needed external bridges. The 64KB Flash comfortably fits OSEK/ AUTOSAR-light firmware plus bootloader, while 16KB RAM supports a small RTOS and CAN message buffers. Drop-in upgrade path to PIC32MX330F064H exists if more code space is needed without PCB changes.
Recommended
Industrial HMI / Touch Panel
PIC32MX330F064LT-V/PF suits industrial HMI panels where cost-sensitive 32-bit performance plus a graphics-friendly peripheral set are required. The CTMU and 10-bit ADC enable capacitive touch sensing for buttons or sliders, while the PMP peripheral drives external LCD controllers. Two I2S ports allow audio feedback for alarms or voice prompts. Industrial -40C to +105C operation tolerates cabinet environments. 64KB Flash holds graphics tables and UI firmware; for richer UIs, migrate to PIC32MX270F512L-V/PF with 512KB Flash on the same footprint without PCB rework.
Recommended
USB Peripheral / Data Logger
PIC32MX330F064LT-V/PF integrates USB-OTG on-chip, eliminating external PHY cost for USB peripherals and data loggers. The 80MHz core, 64KB Flash, and 16KB SRAM are sufficient to implement CDC, HID, or vendor-class USB stacks plus local buffering. Two I2C and two SPI ports connect to external sensors, flash, or RTCs. The 100-pin TQFP exposes enough I/O for status LEDs, buttons, and SD-card interfaces. AEC-Q100 qualification also supports automotive-grade data acquisition such as OBD-II loggers and fleet telematics units.
Recommended
Audio Bridge with I2S
PIC32MX330F064LT-V/PF integrates two I2S ports, making it well suited for audio bridges between digital microphones, codecs, and DSPs. The 100-pin TQFP package exposes enough I/O to drive status indicators and user controls alongside the audio path. 64KB Flash fits small audio processing firmware or a bridge-only design, while 16KB RAM supports short audio buffers. For more processing, the PIC32MX250F256L-V/PF provides 256KB Flash on the same footprint, allowing additional codec support and protocol stacks without PCB changes.
Recommended
CAN Node Endpoint
PIC32MX330F064LT-V/PF serves as a CAN node endpoint with on-chip CAN, two SPI/I2S, and five 16-bit timers for PWM-actuated loads. The 80MHz core and 64KB Flash support CANopen or J1939 stacks in compact industrial vehicles, while 16KB RAM handles message queues. AEC-Q100 Grade 2 qualification allows under-hood or chassis-mounted nodes. Drop-in upgrade to PIC32MX330F064H is available if your CANopen implementation needs additional object dictionary space. Pair with external CAN transceivers such as MCP2551 for robust bus isolation.
Recommended
Motor Control Front-End
PIC32MX330F064LT-V/PF works as a motor control front-end where the 5 x 16-bit timers, PWM channels, and QEI interfaces simplify closed-loop control. The 80MHz MIPS32 M4K core executes field-oriented control loops with deterministic timing, while 64KB Flash holds the motor-control library and application code. AEC-Q100 Grade 2 qualification makes it suitable for automotive auxiliaries such as fans and pumps. For higher-power or multi-axis motors, migrate to PIC32MK or dsPIC33 families; this part remains an excellent low-cost single-axis driver.

Key Differentiators
- Automotive AEC-Q100 Grade 2 qualified at 100-pin TQFP footprint (vs PIC32MX330F064LT-I/PF)
- On-chip USB-OTG and CAN in same 100-TQFP device (vs PIC32MX270F512L-V/PF)
- 5 x 16-bit timers plus QEI support for motor control (vs PIC32MX230F128L-V/PF)
Design Notes
PIC32MX330F064LT-V/PF requires a single 2.3V to 3.6V rail with multiple VDD/VSS pin pairs that must all be connected to maintain power integrity. Decoupling must include a 10uF bulk cap near the regulator plus 0.1uF ceramic caps on each VDD pin pair. For automotive applications, place a reverse-polarity and load-dump protection FET ahead of the LDO supplying the MCU.
The 100-TQFP (14x14 mm) at 0.5mm pitch requires 4-layer PCB with 0.2mm via-in-pad or tented vias under the exposed pad row. Maintain at least 0.2mm clearance between traces and 0.4mm width, plus matched 50-ohm impedance on USB D+/D- pair. Place the 8MHz primary crystal within 10mm of OSC1/OSC2 with a guarded ground ring to reduce EMI susceptibility.
Do not exceed 3.6V on any digital I/O or analog pin - the absolute maximum Vih is 3.6V even though the ADC reference may be 3.3V. Never drive MCLR low during normal operation; use the internal voltage regulator disabled (SODIS) bit only when an external 1.8V regulator is provided. Ensure unused pins are configured as outputs low or inputs with pull-ups to avoid shoot-through during sleep modes.
USB D+/D- traces must be 90-ohm differential, matched within 0.5mm, and routed over a continuous ground plane. Avoid stubs and keep total length under 50mm for Full-Speed. CAN bus traces require 120-ohm characteristic impedance and a single termination at each bus end; keep CAN away from switching power traces and cross them at 90 degrees only.
