PIC32MX150F128D-V/PT Overview
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O onto one silicon die. The PIC32MX1xx family specifically targets cost-sensitive embedded designs that require USB connectivity, audio/graphics interfaces, and a richer analog feature set than 8-bit or 16-bit MCUs can offer, sitting between PIC24/dsPIC33 and the higher-end PIC32MX3xx/4xx families in the Microchip portfolio.
Key features include 128 KB (131 KB per MicrochipUSA) of Flash with self-programmable flash, 32 KB of SRAM with cache, 21 general-purpose I/O pins with Peripheral Pin Select (PPS) remapping, and an on-chip 1 Msps 10-channel 10-bit ADC. It also embeds five 16-bit general-purpose timers, a Charge Time Measurement Unit (CTMU) for mTouch capacitive touch sensing, an analog comparator, and an on-chip temperature sensor for board-level monitoring.
Architecturally, the M4K core executes most instructions in a single cycle with a 5-stage pipeline, supports hardware multiply/divide, and provides separate Flash and SRAM buses so the CPU can fetch instructions while DMA moves peripheral data. The USB OTG controller, integrated voltage regulator, and wide peripheral mix reduce external component count, while PPS allows pin-function remapping to simplify PCB routing in densely populated designs.
Typical applications include USB audio interfaces and MIDI peripherals, low-cost HMI panels with the PMP driving LCDs, capacitive-touch user interfaces using CTMU, industrial control nodes requiring USB-CDC bridges, and low-power sensor hubs where the <0.5 mA/MHz figure enables battery-friendly duty-cycled designs.
When designing with this MCU, leave room in the Flash budget for the USB stack and any bootloader. Place the 2.5 V USB transceiver bypass capacitors per datasheet recommendations, and use the PPS feature to route I²S, UART, or timer channels to convenient pins without re-spinning the schematic.

Typical Applications
PIC32MX150F128D-V/PT is suitable for 6 applications: USB Audio Device, Capacitive Touch HMI, Graphics / PMP-Controlled LCD Panel, USB-to-UART / CDC Bridge, Industrial Sensor Node, MIDI / USB-MIDI Controller.
USB Audio Device
The PIC32MX150F128D-V/PT fits USB audio class peripherals because it integrates a USB 2.0 Full-Speed OTG controller with internal PHY, two I²S/SPI modules for stereo audio data to an external codec, and 32 KB of SRAM to buffer USB isochronous packets. Its <0.5 mA/MHz active current lets bus-powered designs stay under USB suspend current. The 128 KB Flash holds a USB audio class driver plus a small DSP pass-through. Compared to adding an external USB bridge IC, this single-chip solution reduces BOM cost by $0.80-$1.50 and saves 30-50 mm² of PCB area in compact audio dongles.
Recommended
Capacitive Touch HMI
The PIC32MX150F128D-V/PT is well-suited to capacitive touch user interfaces because it integrates the Charge Time Measurement Unit (CTMU), which provides hardware-timed capacitance measurement with sub-percent accuracy and 1 ns resolution. Microchip's mTouch libraries run on this core and support touch buttons, sliders, and proximity sensors with minimal CPU overhead, freeing the MIPS M4K to handle LED feedback, beepers, or UART commands. The 21 I/O pins via PPS allow flexible routing of the touch channels to PCB ergonomic locations. End products include white-goods panels, smart switches, and appliance user interfaces where BOM cost is critical.
Recommended
Graphics / PMP-Controlled LCD Panel
The PIC32MX150F128D-V/PT fits cost-driven graphics applications because it integrates a Parallel Master Port (PMP) that drives small color TFTs and character/graphical LCDs at up to 16-bit parallel bus width without an external LCD controller. The 32 KB SRAM supports framebuffer-less text rendering plus a small icon cache, while USB OTG enables host-side firmware updates from a USB stick. The 40 MHz MIPS M4K delivers ~1.5 DMIPS/MHz, sufficient for menu navigation, simple gauges, and animated icons. This combination targets low-end HMI panels and appliance control boards where a $5-$10 BOM savings vs higher-tier PIC32MX5xx/6xx parts is significant.
Recommended
USB-to-UART / CDC Bridge
The PIC32MX150F128D-V/PT is a strong fit for USB CDC virtual COM port bridges because the integrated USB OTG controller plus UART peripherals allow a single chip to replace FTDI-style bridges at $0.50-$1.00 BOM savings. The 128 KB Flash is more than sufficient for the USB CDC stack and any command-line parsing, and the 32 KB SRAM handles USB packet buffering plus UART FIFOs. PPS remaps serial pins to ease PCB routing when a USB-C connector and a DB-9 are placed at opposite ends of the board. Industrial modules, debug boards, and legacy RS-232 retrofits benefit from this integration.
Recommended
Industrial Sensor Node
The PIC32MX150F128D-V/PT suits battery-friendly industrial sensor nodes because its <0.5 mA/MHz active current plus low-power sleep modes enable multi-year battery life when duty-cycled. The 10-bit 1 Msps ADC reads analog sensors directly, the on-chip temperature sensor simplifies cold-junction compensation or board-level monitoring, and CTMU supports touch/proximity wake. USB OTG provides a charging and data-port interface for field-deployed sensors that occasionally connect to a host. The -40C to +105C temperature range supports outdoor enclosures, smart-meter peripherals, and HVAC sensor clusters.
Recommended
MIDI / USB-MIDI Controller
The PIC32MX150F128D-V/PT is a good fit for USB-MIDI controllers because the integrated USB OTG controller with full-speed USB handles the MIDI class driver natively, and the two I²S/SPI modules plus 5 general-purpose 16-bit timers drive buttons, encoders, and LED feedback with low jitter. The 21 I/O pins via PPS support up to 16 multiplexed MIDI buttons, 4 rotary encoders, and an LED matrix. At 40 MHz MIPS M4K, latency from button press to USB-MIDI message is well under 1 ms, well below the perceptible musical-instrument threshold. End products include compact MIDI foot controllers, pad controllers, and DJ controllers.

Key Differentiators
- Integrated USB 2.0 Full-Speed OTG with internal PHY (vs PIC32MX150F128B-I/SP)
- Parallel Master Port for graphics LCDs (vs PIC24HJ64GP504-I/PT (16-bit DSC))
- Higher temperature range (-40C to +105C) vs industrial-only siblings (vs PIC32MX150F128D-I/PT (industrial -40C to +85C))
Design Notes
The PIC32MX150F128D-V/PT integrates a 2.5 V core LDO that derives from the 2.3-3.6 V VDD rail. Place a 10 uF bulk capacitor plus a 0.1 uF decoupling cap within 5 mm of every VDD pin, and a 10 uF + 0.1 uF pair on AVDD. For USB VBUS sensing, route VBUS through a 10 kOhm resistor divider if your system is bus-powered, and add a 4.7 uF bulk capacitor on VBUS. Estimated: total bulk cap budget for stable USB operation is approximately 30-40 uF.
Route the USB D+ and D- lines as a 90 ohm differential pair with length matching to within 2 mm. Place the ESD protection array within 3 mm of the USB connector and keep the trace stub to the PIC32MX150F128D-V/PT pins under 5 mm. Keep the 24 MHz primary oscillator traces short and symmetric, with a ground guard ring. Avoid routing PWM or PMP signals across the USB differential pair to prevent EMI coupling that can degrade USB eye-diagram compliance.
Do not exceed 3.6 V on any I/O pin even briefly; the silicon is not 5 V tolerant. When using Peripheral Pin Select (PPS), ensure the input pin you select actually has the peripheral mapping you want - some pins cannot be mapped to certain functions. For CTMU-based touch sensing, calibrate at production temperature to avoid drift; the datasheet recommends a 2-point calibration at 25C and 50C. Estimated: CTMU raw count varies by ~0.1% per degree C without calibration.
At 40 MHz with all peripherals active, the PIC32MX150F128D-V/PT consumes under 25 mA from VDD, dissipating approximately 80 mW in a 3.3 V system. The 44-pin TQFP package has theta_JA around 50 C/W (per Microchip package thermal data), so the junction rises by ~4C above ambient - no heatsink needed. Estimated: at the upper -40C to +105C operating limit, ensure ambient stays below 100C to leave thermal margin.
Compliance Information
RoHS compliant per Microchip product page. AEC-Q100 qualification status not explicitly confirmed in the verified web data - manufacturer site notes the part meets AEC-Q100 standards per MicrochipUSA listing, but Microchip's official parametric search should be consulted for the exact grade.
