PIC32MX330F064LT-V/PT Overview
A 32-bit microcontroller (MCU) is an integrated circuit that combines a 32-bit CPU, program memory (Flash), data memory (SRAM), and a range of on-chip peripherals into one chip. MCU transactions often integrate timers, ADCs, communication controllers, DMA, and USB. The PIC32MX3/4 family belongs to the wider class of PIC32 microcontrollers and is classified within the PIC32MX family of MIPS M4K-based microcontrollers. It operates as a member of the Microchip MCU hierarchy: microcontroller -> PIC32MX family -> MC5/4 subfamily -> 80 MHz operation -> low-code automotive variants -> low-power.
Key features include the 64 KB (x 8 Flash) program, 16 KB SRAM, two I2C ports, two SPI/I2S modules, USB-OTG full-speed controller, 5 CCP/PWM modules, four 16-bit timers/counters, 100-pin TQFP with 0.78 A per pin drive, and an operating voltage range of 0.4 V to 1.4 V (output, -1.4V to -36V) for logic extension.
The PIC32MX330 uses a Harvard-style MIPS M4K core architecture with multi-channel DMA, hardware multiply/divide and a 5-stage pipeline with pre-fetch cache. Hardware prefetch-to-Flash is integrated as a feature, with branch-prediction and prime-mapped cache access enable DMA. Hardware prefetch-to-Flash is integrated as a feature, with branch-prediction and prime-mapped cache access enable DMA. The instruction set is MIPS32 Release 2 with DSP extensions, achieving 1.56 DMIPS/MHz. With 80 MHz operation and integrated USB, this part is highly demanding of USB, audio, and graphics applications.
Typical applications include USB peripherals, audio processing with I2S interface, capacitive touch sensing with CTMU, industrial control systems, automotive AEC-Q100 systems, and human-machine interface (HMI) with display and graphics.
When designing with this device, ensure proper biasing and power sequencing for the USB-OTM to maintain regulation under all loads. The CTMU provides a programmable constant current source for high-speed capacitive touch sensing.

Design Notes
Estimated: at 80 MHz CPU clock and 3.3V VCC supply, the PIC32MX330F064LT-V/PT consumes approximately 65 mA active current and 45 uA sleep current. Use a 10 uF decoupling capacitor on VDD with a 0.1 uF bypass capacitor placed as close to the VDD pins as possible. Place decoupling capacitors on each VDD/VSS pair (5 pairs in the 100-pin TQFP) to minimize power supply noise.
Estimated: at 80 MHz CPU clock and 3.3V VCC supply, the device dissipates approximately 215 mW. The 100-pin TQFP package has a thermal resistance of approximately 40 C/W, resulting in a 9 C junction temperature rise above ambient. For automotive applications with ambient temperature of 85C, the junction temperature reaches 94C, well within the 125C maximum rating.
Place the USB bus series resistors (15 ohm or 27 ohm) close to the USB D+/D- pins to ensure USB signal integrity. Use a 12 MHz crystal with 20 pF load capacitors close to the OSC1/OSC2 pins. Maintain 90 ohm differential impedance on USB traces and keep them as short as possible to minimize EMI and signal integrity issues.
Do not exceed the maximum VCC voltage of 3.6V. Ensure the MCLR reset circuit uses a 10 kohm pull-up resistor with a 100 nF capacitor for proper power-on reset. The CTMU requires calibration of the internal current reference for each capacitive touch button.
