PIC32MX150F128D-I/ML Übersicht
What is a 32-bit MCU? A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripherals such as timers, ADCs, and communication interfaces. The PIC32MX1XX/2XX family uses the MIPS32 M4K core, placing these parts in the microcontroller -> 32-bit MCU -> MIPS-based MCU -> embedded controller taxonomy, and within Microchip's broader portfolio they sit alongside the PIC24 and dsPIC families as general-purpose embedded controllers with DSP-class throughput.
Key features of the PIC32MX150F128D-I/ML include five 16-bit timers/counters, two I2C ports, two UART ports, two SPI/I2S ports, a 10-bit 1 Msps ADC with up to 28 analog inputs, an on-chip temperature sensor, a 5-bit DAC, and 34 digital I/O pins. PPS allows remapping of digital peripheral signals to most I/O pins, simplifying PCB routing in densely packed designs.
Architecturally, the part uses a 5-stage pipeline MIPS32 M4K core with hardware multiply/divide and a Prefetch Cache Module that fetches 16-bit words from Flash and presents 32-bit instructions to the core. The dual-bank Flash with live-update support enables in-field firmware upgrades, and the 32 KB SRAM provides ample headroom for USB stacks, graphics framebuffers, and audio processing buffers.
Typical applications include USB audio devices (USB speakers, headphones, and headsets), low-cost graphics HMI with PMP-driven TFT panels, capacitive touch key/slider front panels using CTMU, industrial control with on-chip 10-bit ADC, and consumer devices requiring USB connectivity. The wide peripheral mix and USB make the part a single-chip solution for many USB+graphics products.
A key design consideration is that the 44-QFN part exposes fewer I/O than the 64-pin variants; designers needing more pins should consider the PIC32MX150F128D-I/PT (44-TQFP, same pinout assignment) or migrate to PIC32MX250/270 64-pin devices for additional peripherals. Ensure VUSB decoupling follows the USB specification and the VBAT/AVDD rails are properly sequenced.

Typische Anwendungen
PIC32MX150F128D-I/ML ist geeignet für 6 Anwendungs: USB Audio Devices, Low-Cost Graphics HMI, Capacitive Touch Key/Slider Panels, Industrial Control Modules, Consumer USB Peripherals, Audio Processing and DSP.
USB Audio Devices
The PIC32MX150F128D-I/ML is a natural fit for USB audio applications: its integrated USB 2.0 Full-Speed device controller with on-chip transceiver eliminates the need for an external PHY, while 32 KB SRAM comfortably buffers USB isochronous audio packets, and two I2S ports drive external DACs/ADCs directly. At 40 MHz MIPS M4K throughput, the MCU handles USB stack overhead plus I2S streaming at 48 kHz/16-bit without CPU saturation. The part is widely used in USB speakers, USB headsets, and USB microphones where a single-chip BOM reduces cost and PCB area.
Empfohlen
Low-Cost Graphics HMI
The PIC32MX150F128D-I/ML drives low-cost TFT LCD panels through its Parallel Master Port (PMP) at up to 40 MHz, supporting 8-bit and 16-bit 8080/6800 interface modes common in small QVGA/WQVGA displays. The 32 KB SRAM is enough for a partial framebuffer at lower color depths, while PPS lets designers route PMP data, control, and address pins to any convenient I/O. At 40 MHz, the MCU refreshes QVGA panels at full frame rate with simple on-screen UI rendering, making the PIC32MX1 a single-chip solution for low-cost HMI in appliances, instruments, and consumer products.
Empfohlen
Capacitive Touch Key/Slider Panels
The PIC32MX150F128D-I/ML integrates Microchip's Charge Time Measurement Unit (CTMU), enabling up to 28 mTouch capacitive touch channels without external touch ICs. The CTMU measures charge/discharge time on sense electrodes with 1 ns resolution, detecting proximity through thin overlays. Combined with PPS flexibility and 32 KB SRAM, designers can implement sliders, wheels, and button matrices in consumer white goods, IoT controls, and appliance front panels. Microchip's mTouch library provides ready-to-use firmware for the PIC32MX1 family, reducing development time significantly.
Empfohlen
Industrial Control Modules
The PIC32MX150F128D-I/ML is suited for industrial control with its 10-bit 1 Msps ADC (up to 28 channels) handling sensor inputs, five 16-bit timers for PWM motor control, and 34 digital I/O for switch and relay interfaces. Industrial -40C to +85C operation suits factory environments, and USB enables configuration/diagnostics links to host PCs. With 128 KB Flash and 32 KB SRAM, the MCU runs control loops, communication stacks, and PID algorithms simultaneously. Common uses include PLC expansion modules, sensor hubs, and motor controllers in industrial automation.
Empfohlen
Consumer USB Peripherals
The PIC32MX150F128D-I/ML excels in USB peripherals such as keyboards, mice, gamepads, and HID-class devices because of its integrated USB 2.0 FS controller and 128 KB Flash for HID report descriptors. The 32 KB SRAM holds USB stack plus application logic, while PPS allows flexible PCB routing of D+/D- and GPIO. At 40 MHz, the MCU handles USB polling and HID input scanning simultaneously. Microchip's free USB stack and HID bootloader shorten development time for consumer USB accessories.
Empfohlen
Audio Processing and DSP
The PIC32MX150F128D-I/ML supports audio processing through its two I2S ports (full-duplex), 10-bit ADC for microphone capture, 5-bit DAC for simple tone output, and DSP-class MIPS throughput at 40 MHz. The MCU implements audio effects, equalizers, codecs, and signal processing on I2S streams, making it suitable for prosumer audio gear. Microchip's DSP library provides FIR, IIR, and FFT primitives targeting the MIPS M4K core. The combination of I2S + USB enables USB audio interfaces and DSP effects in a single chip.

Wichtigste Unterscheidungsmerkmale
- Integrated USB 2.0 Full-Speed with on-chip transceiver (vs. PIC32MX130F064B-I/SS (no USB))
- Automotive-grade variant available in same package (vs. PIC32MX150F128D-V/ML (automotive variant))
- Higher-speed 50 MHz upgrade with same pinout (vs. PIC32MX250F128D-I/ML)
Designhinweise
The PIC32MX150F128D-I/ML operates from 2.3 V to 3.6 V with multiple VDD/VSS pin pairs on the 44-QFN package. Decouple each VDD pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, plus a single 10 uF bulk capacitor near the package. The USB VBU rail needs 0.1 uF + 4.7 uF decoupling. Power sequencing is not required; however, inrush current on cold-plug USB applications should be limited with a soft-start circuit on the upstream 5V regulator.
The 44-QFN (ML) 8x8 mm package has a center thermal pad that must be soldered to a PCB land for mechanical reliability and thermal dissipation. The thermal pad land should be tied to the digital ground plane with multiple thermal vias (0.3 mm drill, 0.6 mm pitch) for heat spreading. Maintain 4 mil trace/space design rules around QFN lands and avoid routing signal traces under the package. Use a 0.5 mm pitch QFN footprint per the Microchip package drawing in the datasheet.
A common pitfall is forgetting to configure Peripheral Pin Select (PPS) registers before using remappable peripherals such as UART, SPI, or PWM outputs. PPS must be unlocked via CFGCON register write sequence before remapping. Another pitfall is using the USB peripheral without enabling the on-chip 96 MHz PLL via OSCCON, leading to USB enumeration failures. Always initialize the PLL to 48 MHz for USB Full-Speed operation before connecting to a host. Designers should also ensure the JTAG/ICSP pins are not accidentally remapped if in-circuit programming is needed for field updates.
Compliance-Informationen
RoHS compliant per Microchip product page. The -V/ML sibling variant is AEC-Q100 qualified for automotive; the -I/ML industrial variant is not.
