PIC32MX150F128DT-50I/ML Обзор
A microcontroller (MCU) is a single-chip computer containing a processor core, program and data memory, and programmable peripherals. The PIC32MX family sits in the hierarchy: 32-bit MCU -> MIPS32 M4K CPU -> PIC32MX sub-family -> Microchip 32-bit microcontroller portfolio. Within Microchip's catalog, this part is positioned in the PIC32MX1XX/2XX 28/36/44-pin general-purpose sub-family optimized for audio, graphics, USB, and analog-intensive applications.
Key features include two I2S/SPI modules for audio codec interfaces, Peripheral Pin Select (PPS) for flexible pin-function routing, a Parallel Master Port (PMP) for graphics and external memory, mTouch capacitive-touch hardware support, a 1 ns resolution time-measurement capture input, an on-chip temperature sensor, and sub-0.5 mA/MHz active current consumption for low-power designs. The 44-QFN-EP package with exposed pad provides excellent thermal dissipation for the 50 MHz performance.
The PIC32MX150F128DT-50I/ML uses a 5-stage pipeline Harvard architecture with a hardware Multiply/Divide unit, supporting the MIPS32 instruction set. With a 2.3 V to 3.6 V supply, 50 MHz operation delivers up to 50 MIPS throughput. The 44-pin variant exposes up to 35 GPIOs via PPS, two I2C, two SPI, two UART, an ADC module with up to 28 channels, and a 16-bit Parallel Master Port.
Typical applications include USB audio interfaces, color graphics HMI with PMP-connected LCD, capacitive touch control panels, low-power industrial sensing nodes, and consumer audio peripherals such as Bluetooth speakers and digital headsets. The mTouch and I2S modules directly serve audio and human-input use cases.
When designing with this part, ensure the exposed pad is soldered to a continuous ground copper pour for proper thermal dissipation. Decouple VDD with 0.1 µF + 1 µF ceramic capacitors placed within 5 mm of each supply pin, and route the 50 MHz crystal traces short and symmetrically.

Типичное применение
PIC32MX150F128DT-50I/ML подходит для 6 применениеs: USB Audio Headset Interface, Color Graphics HMI with PMP-LCD, Capacitive Touch Control Panel, Industrial Sensor Hub Node, Bluetooth Audio Dongle Host MCU, Consumer Coffee Machine / White-Goods Controller.
USB Audio Headset Interface
The PIC32MX150F128DT-50I/ML fits USB audio-headset applications because its two I2S/SPI modules directly interface with audio codecs (e.g. PCM5101A, SGTL5000) while the 50 MHz MIPS32 M4K core delivers enough throughput to run a USB Audio Class 1.0 stack plus DSP volume/effects processing. With 128 KB Flash and 32 KB RAM, it can host a small RTOS, USB descriptors, and audio buffering without external memory. The exposed pad on the 44-QFN-EP package keeps junction temperature within spec while continuously streaming 48 kHz/16-bit stereo audio. Compared to a 8-bit MCU, the PIC32MX150 adds headroom for future Bluetooth or ANC feature upgrades.

Color Graphics HMI with PMP-LCD
The PIC32MX150F128DT-50I/ML drives small color TFT HMI displays using the on-chip Parallel Master Port (PMP), which can directly connect to 8/16-bit 8080 or 6800 interface LCDs. At 50 MHz the core can refresh a QVGA panel at 30+ FPS while still servicing touch input via mTouch and a serial command set. The 128 KB Flash accommodates Microchip's MPLAB Harmony graphics library, custom fonts, and bitmaps. The 44-QFN-EP (8x8 mm) footprint is ideal for compact appliance or industrial front-panel PCBs. Compared to using a higher-end MCU, the PIC32MX150 trims BOM cost while still delivering smooth graphics on small displays.
Рекомендуется
Capacitive Touch Control Panel
The PIC32MX150F128DT-50I/ML is well suited for mTouch capacitive touch button/slider panels because its on-chip mTouch hardware support, combined with Peripheral Pin Select (PPS), lets the designer route scan channels to any GPIO without external muxes. The <0.5 mA/MHz active current keeps idle-mode power low for battery-powered remotes and white-goods interfaces. The 44-QFN-EP (8x8 mm) package supports dense sensor routing on multi-layer PCBs. The 1 ns resolution time-measurement capture input ensures robust proximity and water-tolerance tuning. Compared to a discrete touch IC plus host MCU, the integrated solution reduces BOM and simplifies firmware maintenance.
Рекомендуется
Industrial Sensor Hub Node
The PIC32MX150F128DT-50I/ML fits low-power industrial sensor-hub nodes where it can aggregate data from UART, SPI, and I2C sensors, perform local filtering or thresholding, and forward events upstream. The 50 MHz MIPS32 M4K core provides headroom for lightweight DSP such as moving averages and RMS calculations, while 32 KB SRAM is sufficient for sensor FIFOs. The 2.3-3.6 V supply lets the node run from a 3.3 V LDO directly fed by a 24 V industrial bus. The exposed thermal pad on the 44-QFN-EP package maintains reliability in enclosed industrial cabinets up to +85 °C. Compared to a Cortex-M0+ part at the same MHz, the PIC32MX150 offers a wider MIPS throughput margin for protocol stacks.
Рекомендуется
Bluetooth Audio Dongle Host MCU
The PIC32MX150F128DT-50I/ML serves as the host MCU in a Bluetooth audio dongle, where it bridges an external BT module's UART or I2S interface to a local DAC/headphone amplifier. The two I2S/SPI modules support simultaneous upstream and downstream audio paths, while the 50 MHz core handles SBC or AAC decoding at low bit rates. The 128 KB Flash accommodates codec libraries and BT stack wrappers. The 44-QFN-EP package keeps the dongle footprint minimal for USB-stick form factors. Compared to a fixed-function BT audio SoC, the PIC32MX150 offers upgradeable firmware and a flexible peripheral set.
Рекомендуется
Consumer Coffee Machine / White-Goods Controller
The PIC32MX150F128DT-50I/ML is a strong fit for consumer white-goods controllers (coffee machines, microwave ovens, induction cooktops) where a single MCU must run a UI on a small graphic LCD, scan capacitive touch keys, drive a triac/PWM via timer, and read sensors over UART/SPI. The PMP drives the LCD directly, the mTouch engine scans buttons without an external IC, and the 50 MHz MIPS32 core runs the UI loop within milliseconds. The 44-QFN-EP (8x8 mm) package provides good thermal performance in enclosed appliance housings up to +85 °C. Compared to an 8-bit PIC16 + dedicated touch IC, the PIC32MX150 simplifies the BOM and reduces firmware complexity.

Заметки по проектированию
The 44-QFN-EP package dissipates heat primarily through the exposed thermal pad. Per Microchip's package drawing, the EP must be soldered to a continuous ground copper pour on the top layer with at least 8 thermal vias to an internal ground plane. Without proper EP soldering, junction temperature can rise 15-25 °C above ambient at 50 MHz with all peripherals active, risking thermal shutdown in enclosed housings.
Decouple each VDD/VSS pair with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, plus a bulk 1 µF X7R capacitor on each rail. Route the 50 MHz primary crystal traces (OSC1/OSC2) symmetrically with the crystal within 0.5 inch of the MCU and guard them with a ground keep-out. Keep high-speed digital traces (PMP, SPI) away from the ADC analog inputs (AN0-AN15) to minimize coupling noise.
The PIC32MX150F128DT-50I/ML draws <0.5 mA/MHz when active. Estimated: at 50 MHz full peripherals, total active current is ~25 mA + peripheral contribution. Use a low-dropout regulator such as MCP1825 with 3.3 V output and 300 mA rating for headroom. Add a ferrite bead + 10 µF bulk cap on the 3.3 V rail feeding the MCU to suppress noise from digital I/O switching back into the ADC reference.
Do not exceed 3.6 V on any VDD pin - the part is not 5 V tolerant on I/O. When programming via ICSP, ensure PGED1/PGEC1 lines have proper pull-ups as specified in the datasheet, or use the MPLAB ICD 4 / PICkit 4 in-circuit debugger. Peripheral Pin Select (PPS) mappings must be configured in firmware before using remappable functions; remapping to an unmapped input is a common source of 'dead' peripherals at first bring-up.
