A PIC32MX-class MCU is a high-performance 32-bit microcontroller from Microchip's PIC32 family based on the MIPS32 M4K architecture. PIC32MX parts target cost-sensitive embedded applications that need the throughput of a 32-bit core (up to 83 DMIPS), generous Flash/RAM, and rich connectivity for USB, graphics, audio, and control. Within the taxonomy, PIC32MX150F256H sits under PIC32MX150 -> PIC32MX1xx -> PIC32MX family -> PIC32 -> 32-bit Microcontrollers -> Microcontrollers -> Integrated Circuits.
Key features include 50 MHz/83 DMIPS core performance, 256 KB Flash, 32 KB RAM, full-speed USB 2.0 device, Peripheral Pin Select for flexible pin mapping, PMP with dual buffers for graphics, four-wire SPI/I2S for audio codecs, and an industrial -40C to +85C operating range. The combination of large memory and a broad peripheral set makes this part well suited for USB-connected and graphics-oriented designs.
From a system-design perspective, the PIC32MX150F256H integrates a 5-channel DMA controller, a 16-bit Parallel Master Port with dual buffers for graphics, and PPS that remaps most digital peripherals to almost any I/O pin. This greatly simplifies PCB routing and lets engineers reuse a single PCB layout across multiple PIC32MX150-family derivatives. The 50 MHz/83 DMIPS core delivers deterministic interrupt latency for real-time control loops.
Typical applications include USB audio and HID peripherals, small graphical HMI panels driven by PMP, low-cost barcode scanners, sensor hubs, and connected industrial controllers. The wide operating range (3.0-3.6 V core) and -40C to +85C industrial temperature range suit it for both commercial and industrial environments.
When designing with this part, follow the Microchip PIC32MX1xx/2xx family reference manual for oscillator, USB, and ICSP layout. Decouple VDD/VSS with 100 nF ceramics placed within a few millimetres of each pin pair, and respect the VBUS/VUSB capacitance requirement of 0.47 uF on the USB transceiver pins.

典型應用
PIC32MX150F256HT-50I/PT 適用於 7 應用s: USB Audio Headset / DAC Peripheral, Small Graphics HMI Panel (PMP), Industrial Sensor Hub / USB Bridge, Connected IoT Edge Controller, USB Barcode / Scanner HID, Test & Measurement Front Panel, Automotive Infotainment Sub-System.
USB Audio Headset / DAC Peripheral
The PIC32MX150F256HT-50I/PT is a strong fit for USB audio peripherals such as external USB soundcards and USB headsets. Its integrated USB 2.0 full-speed device controller with isochronous endpoint support and on-chip transceiver eliminates the need for an external PHY, while two I2S interfaces connect directly to common audio codecs (e.g., S/PDIF transmitters, stereo DACs) without extra glue logic. At 50 MHz/83 DMIPS, the core sustains stereo 16-bit/48 kHz audio streams with comfortable headroom for DSP effects, volume control, and LED status feedback. The 32 KB SRAM is sufficient for audio buffering plus USB descriptors and class-state machines. Reference firmware from Microchip Harmony's UCDC/Bundle simplifies USB Audio Class 1.0 enumeration.

Small Graphics HMI Panel (PMP)
The PIC32MX150F256HT-50I/PT drives small graphical HMI panels via the Parallel Master Port (PMP) with dual read/write buffers, making it suitable for low-cost menu UIs and indicator screens. The 50 MHz core delivers fast pixel writes to color QVGA TFTs, while 256 KB Flash accommodates full-frame buffers plus UI firmware. The 10-bit ADC reads touch panels or analog front-ends alongside the display, and PPS lets designers route SPI touch controllers or LED PWM timers without PCB rework. Industrial -40C to +85C temperature range supports factory HMI enclosures.
推薦
Industrial Sensor Hub / USB Bridge
For industrial sensor hubs, the PIC32MX150F256HT-50I/PT aggregates I2C sensors, SPI devices, UART field buses, and analog inputs, then exposes them as a USB HID or CDC composite device to a host PC. Five UARTs handle RS-232/RS-485 via transceivers, four SPI channels address sensor ASICs and flash storage, and the 10-bit ADC up to 1 MSPS samples analog process variables. The -40C to +85C industrial temperature rating and 3.3 V operation suit factory-floor cabinets. PPS lets designers remap peripherals to optimize PCB routing.
推薦
Connected IoT Edge Controller
The PIC32MX150F256HT-50I/PT acts as an IoT edge node with USB to a Wi-Fi or Ethernet bridge, managing sensor acquisition, local pre-processing, and protocol translation. The MIPS32 M4K core executes MQTT-SN or CoAP libraries within 256 KB Flash, while DMA offloads sensor streams to free the CPU for application logic. With five 16-bit/32-bit timers and five UARTs, the MCU handles multiple concurrent sensor buses, and the 3.0-3.6 V VDD range matches battery-backed systems. PPS enables re-mapping digital peripherals to optimize pinout for slim enclosures.
推薦
USB Barcode / Scanner HID
USB barcode scanners and similar USB HID peripherals benefit from the PIC32MX150F256HT-50I/PT's USB 2.0 FS device, four UART channels for imagers, and 32 KB SRAM buffering scan data. The 50 MHz core processes decoded barcode payloads fast enough for high-throughput 1D/2D imagers, and 256 KB Flash holds firmware plus symbology libraries. PMP enables connection to a small preview display, while PPS supports flexible PCB layouts across scanner SKUs.
推薦
Test & Measurement Front Panel
The PIC32MX150F256HT-50I/PT serves as a smart front-panel controller in T&M equipment, providing USB test-and-measurement class (USBTMC) connectivity, rotary encoder inputs, keypads, and segment or character LCD control via PMP. 256 KB Flash holds multiple test scripts and calibration tables, while five UARTs expose serial measurement peripherals. The industrial temperature range suits lab and field deployments, and the 64-pin TQFP footprint simplifies layout across a product family.
推薦
Automotive Infotainment Sub-System
While the PIC32MX150F256HT-50I/PT is not AEC-Q100 qualified, in cabin-infotainment sub-modules and aftermarket accessories its industrial -40C to +85C rating plus USB 2.0 FS device, I2S audio, and PMP graphical capabilities make it a useful controller. The 50 MHz core runs CAN-over-UART bridges, RGB565 status displays, and volume/audio routing with low latency. Combined with the wide VDD range and 32 KB SRAM, it handles typical automotive auxiliary-feature firmware loads with room for diagnostics.

設計說明
The PIC32MX150F256HT-50I/PT operates from 3.0 V to 3.6 V on VDD. Use a 10 uF bulk plus 100 nF ceramic per VDD/VSS pair placed within a few millimetres of each pin, per the PIC32MX1xx/2xx family reference manual. The USB VUSB pin requires a 0.47 uF decoupling capacitor as close as possible to the pin. A power-on-reset brown-out (BOR) is recommended in firmware to ensure deterministic startup from <3.0 V transients.
Place a continuous ground plane beneath the TQFP-64 footprint and route high-speed USB DP/DM traces as a 90 ohm differential pair with matched length and ground stitching vias every few millimetres. Keep the 12 MHz primary oscillator traces short and guard them with a grounded keep-out to minimise EMI. Avoid routing analog ADC traces beneath switching nodes or USB traces.
Do not forget the ICSP programming connector (PGECx/PGEDx) on the final PCB; PIC32 parts require an ICSP interface for in-circuit programming and debugging. When migrating firmware across PIC32MX150F256, PIC32MX130F256, and PIC32MK MCUs, revalidate peripheral mapping because PPS pin selections and I/O count differ. The MPLAB Harmony configurator should be used to regenerate peripheral setup code after migrating core families.
The 50 MHz core clock can emit harmonics up to ~250 MHz; place decoupling capacitors as close to each VDD pin as the PCB allows, and stitch the inner ground plane with frequent vias. For USB DP/DM traces, use the series source termination resistors recommended in the family reference manual to keep the eye diagram compliant. Avoid long parallel runs with switching regulator or PWM signals to keep radiated emissions below EN55022 limits.
