PIC32MX330F064H-V/PT Overview
A 32-bit microcontroller (MCU) is an integrated processor that combines a CPU core, program memory, data memory, and a programmable peripheral set on a single die. The PIC32MX family specifically uses the MIPS32 M4K architecture, which executes most instructions in one cycle and supports up to 150 DMIPS at peak. Within the broader taxonomy, the PIC32MX sits as a mid-range 32-bit MCU -> embedded controller -> semiconductor, offering higher performance than 8/16-bit AVR/PIC16/PIC18 devices and comparable capability to ARM Cortex-M0/M0+ parts.
Key features of the PIC32MX330F064H-V/PT include two SPI/I2S interfaces, up to five 16-bit PWM channels, four DMA channels, a 10-bit ADC with up to 28 channels, a CTMU (Charge Time Measurement Unit) for touch sensing, and an integrated USB 2.0 full-speed device/host/OTG controller. The device operates from 2.5V to 3.6V with 5V-tolerant I/O on selected pins. The 80 MHz version delivers 100 DMIPS and is the lower-speed sibling of the 120 MHz PIC32MX340/350/360/370 variants.
The architecture combines a 5-stage pipeline M4K core with multi-vector interrupt controller and prefetch cache, enabling deterministic real-time response. The peripheral set is mapped via a separate peripheral bus to gain DMA access without latency, which is essential for USB isochronous transfers and high-speed ADC sampling.
Typical applications include industrial control HMI panels, USB audio Class 1 devices, low-cost graphics/touch appliances, sensor hubs, and home appliances requiring USB connectivity plus a rich analog front end. The CTMU enables capacitive touch buttons and sliders without an external touch controller.
When designing with this MCU, allocate careful attention to the USB bus: the device includes an internal USB transceiver but requires an external 48 MHz crystal for full-speed USB operation, and PCB layout must keep the D+/D- traces impedance-controlled and short to pass USB compliance. The -V temperature grade covers -40C to +105C operation for industrial environments.

- CTMU capacitive touch engine on-chip (vs PIC32MX230F128H (no CTMU))
- AEC-Q100 automotive qualification (vs PIC32MX330F064H-I/PT (industrial only))

Design Notes
The PIC32MX330F064H-V/PT operates from a single 2.5V-3.6V supply with peak active current around 70 mA at 80 MHz with USB active. Decouple each VDD/VSS pair with a 100 nF ceramic plus 4.7 uF bulk per the Microchip datasheet DS61143 power-supply section. For USB bus-powered designs, add a 10 uF bulk capacitor on VBUS to handle inrush when the device is first connected. The on-board 1.8V core LDO requires no external inductor.
For USB Full-Speed operation, route the D+ and D- traces as a 90-ohm differential pair with length matching within 150 mil per the USB 2.0 specification. Keep the 48 MHz USB reference crystal within 200 mil of the SOSC0/SOSC1 pins with a grounded copper guard ring. Place the USB connector shield to the chassis ground, not the digital ground, and use an EMI suppression ferrite bead on VBUS to suppress conducted emissions per FCC Part 15 Class B.
Estimated config only - configure the config bits (FPLLIDIV, FPLLMUL, FPLLODIV, FSOSCEN) in code to lock the 80 MHz system clock from the 8 MHz primary oscillator + PLL. Failure to configure PLLFSOSC correctly results in USB enumeration failure (USB requires a 48 MHz clock with 0.25% accuracy). Per Microchip errata, use the latest XC32 compiler v3.00+ to avoid USB stack initialization bugs in earlier versions. Do not enable JTAG pins on RG15/RG14/RG13/RG12 unless JTAG debugging is required - they override GPIO functionality.
Estimated: at full peripheral load (USB + SPI + ADC + PWM simultaneously), the PIC32MX330F064H-V/PT dissipates approximately 250 mW. With TQFP-64 theta_JA around 50 C/W (4-layer PCB with 1 oz copper), junction temperature rises 12C above ambient. The -V/-40C to +105C industrial grade provides adequate margin for fanless enclosures up to 90C ambient. For continuous USB streaming at high ambient, consider a 2 oz copper inner layer to drop theta_JA below 40 C/W.
