PIC32MX150F128D-50I/ML - 50MHz 32-bit MCU 128KB Flash | Microchip
MPN: PIC32MX150F128D-50I/ML ✓ Hoạt độngPIC32MX150F128D-50I/ML Tóm tắt
A 32-bit microcontroller (MCU) is a programmable processor that integrates a CPU core, memory, and peripherals on a single silicon die; PIC32MX1XX/2XX devices use the MIPS32 M4K core, placing them in the broader taxonomy of 32-bit microcontrollers -> microcontrollers -> embedded processors -> semiconductors. PIC32MX parts are widely adopted for cost-sensitive 32-bit designs where ARM Cortex-M parts are over-specified.
Key features include two I2S/SPI modules for codec and serial audio, Peripheral Pin Select (PPS) for flexible signal routing, a Parallel Master Port (PMP) for graphics and external memory interfaces, a Charge Time Measurement Unit (CTMU) supporting mTouch capacitive touch sensing with 1 ns resolution, on-chip temperature measurement, and USB 2.0 full-speed device/host/OTG. The part operates from 2.5 V or 3.3 V with less than 0.5 mA/MHz active current consumption, suiting portable and USB-powered designs.
Architecturally, the M4K core offers single-cycle hardware multiply/divide and a 5-stage pipeline, providing deterministic interrupt latency. The 128 KB Flash and 32 KB SRAM are accessible through the unified 32-bit bus, while the PMP module can address up to 16 MB of external memory in master mode - useful for graphics and audio buffer extensions.
Typical applications include USB audio devices (headsets, dongles, MIDI controllers), capacitive touch user interfaces (mTouch sliders and buttons), low-cost graphics HMI with PMP-connected TFT panels, industrial control front-ends with USB connectivity, and portable consumer electronics requiring 32-bit math without ARM licensing overhead.
When designing with this device, plan I/O carefully: PPS lets remap most digital peripherals to alternate pins, but analog and oscillator pins are fixed. Use the exposed pad (EP) of the QFN-44 package as the primary thermal and ground return path - it must be soldered to a continuous copper pour for rated performance.

Ứng dụng tiêu biểu
PIC32MX150F128D-50I/ML phù hợp cho 7 Áp dụngs: USB Audio Headsets and Dongles, Capacitive Touch User Interfaces (mTouch), Low-Cost Graphics HMI with TFT Panels, USB Industrial Control Front-Ends, MIDI Controllers and USB-MIDI Devices, Portable Consumer Electronics with USB Charging, USB HID Peripherals (Keyboards, Mice, Custom Input Devices).
USB Audio Headsets and Dongles
The PIC32MX150F128D-50I/ML is well-suited to USB audio peripherals thanks to its on-chip USB 2.0 Full-Speed Device/Host/OTG controller with integrated transceiver and 3.3 V regulator. The two I2S/SPI modules connect directly to external audio codecs such as the Microchip LAN/WLAN audio bridge ICs or third-party codecs like the SGTL5000, while the 50 MHz MIPS M4K core handles USB isochronous transfers and audio buffering without overrun. The 32 KB SRAM is sufficient for typical 16-bit/48 kHz stereo streams with headroom for mixing. Total BOM stays low because no external USB PHY is required.

Capacitive Touch User Interfaces (mTouch)
The on-chip CTMU provides 1 ns time measurement resolution, allowing the PIC32MX150F128D-50I/ML to implement Microchip's mTouch capacitive touch library for buttons, sliders, and proximity sensors without external touch ICs. Peripheral Pin Select (PPS) lets the designer remap touch channels to virtually any GPIO, simplifying PCB layout for irregular panel shapes. The 50 MHz core runs the touch scan loop and on-chip temperature compensation in real time, suiting appliance front panels, industrial HMIs, and consumer electronics. PPS also lets the same firmware support multiple board revisions without code changes.

Low-Cost Graphics HMI with TFT Panels
The PIC32MX150F128D-50I/ML includes a Parallel Master Port (PMP) that interfaces directly to 8/16-bit TFT LCD panels and external memory, enabling cost-effective graphical HMIs without an external graphics controller. The 50 MHz core drives QVGA (320x240) panels at 30+ FPS using Microchip's MLA graphics library, while 32 KB SRAM holds the active framebuffer for small panels. Combined with mTouch and USB, the same chip powers appliance, instrument, and industrial-control front panels. Lower BOM cost versus ARM Cortex-M parts with equivalent peripherals is the key advantage.

Ghi chú thiết kế
The 44-pin QFN package with exposed pad dissipates primarily through its underside thermal pad. Solder the EP to a continuous copper pour (minimum 1 square inch on the top layer with thermal vias to inner ground planes) to keep junction temperature within the -40C to +85C industrial range. Estimated: at 50 MHz full CPU load with peripherals active, typical core current is 25 mA at 3.3 V (0.083 W) - well within the package's thermal envelope - but adding USB and CTMU scan loops can push total consumption higher.
Decouple VDD with a 100 nF ceramic capacitor placed within 3 mm of each VDD pin and a bulk 10 uF tantalum or ceramic close to the highest-current VDD pin. Place the USB D+/D- traces as a 90-ohm differential pair (per USB 2.0 spec) with length matching within 2 mm. Keep the 12 MHz crystal traces short and symmetric, and provide a guard ring around the crystal traces tied to ground to reduce EMI.
PPS reassigns most digital peripherals to alternate pins but does NOT work on analog, oscillator, or fixed-function pins (e.g., VBUS, D+, D-, OSC1, OSC2). Always consult the PIC32MX1XX/2XX family pinout table before PCB layout. JTAG pins are multiplexed with GPIO and are disabled by default - if JTAG is not used, configure the pins as GPIO with appropriate pull-downs to avoid floating inputs.
Route the Parallel Master Port (PMP) data and address traces with controlled impedance (50 ohm single-ended) and length-match within 5 mm for reliable operation at full PMP bus speeds. Keep analog input traces (AN0-AN9) short and away from switching signals. Use a separate analog ground island for ADC reference and analog supply pins, stitched to the main ground at a single point near the QFN exposed pad.
USB 2.0 Full-Speed signal integrity requires 90-ohm differential impedance on D+/D-, with a common-mode choke or ferrite bead recommended near the USB connector for EMI. Match trace lengths to within 150 mil (about 4 mm) per the USB 2.0 specification. The internal USB transceiver pulls D+/D- to 3.3 V through internal resistors - external 15 kohm pull-downs on D+ and D- are NOT required for bus-powered devices, per the Microchip datasheet.
