MPN: PIC32MX150F128DT-V/ML ✓ فعالPIC32MX150F128DT-V/ML نمای کلی
A PIC32MX-class MCU is a 32-bit microcontroller from Microchip's PIC32 family that combines the MIPS32 M4K core with PIC peripheral ease-of-use, targeting embedded applications that need more compute than 8/16-bit PIC MCUs but want the familiar PIC ecosystem (MPLAB X, Harmony, XC32 toolchain). It belongs to the broader category of 32-bit microcontrollers -> RISC MCU -> embedded processor -> semiconductor.
Key features include MIPS32 M4K 32-bit core at 40 MHz, 128 KB Flash with 32 KB SRAM, 4-channel hardware DMA with automatic data-size detection, Peripheral Pin Select (PPS) for flexible pin mapping, two UART, two I2C, two I2S/SPI modules, a Parallel Master Port (PMP) for graphics, a 1 ns resolution hardware timer for time measurement, and on-chip temperature measurement. The AEC-Q100 grade and -40C to +105C range suit automotive and industrial environments.
Architecturally the device uses a 5-stage pipeline M4K core with separate instruction and data Flash buses, achieving 1.56 DMIPS/MHz. The Dual-bank Flash supports live update via the panel A/B partitioning scheme, and PPS remaps most digital peripherals to any I/O pin, simplifying PCB routing in space-constrained designs.
Typical applications include automotive HMI and body controllers, industrial control panels with graphical displays, USB-to-UART bridges, low-cost audio processing, capacitive touch (mTouch) interfaces, and sensor hubs. The combination of 128 KB Flash and 32 KB RAM is enough for mid-size state-machine firmware, USB stacks, and small RTOS kernels (FreeRTOS port available).
When designing with this device, remember that 'V' in the suffix indicates the -40C to +105C (V-temp) grade, 'DT' indicates tape and reel with 128 KB Flash, and 'ML' indicates the 44-pin QFN package. A 4-layer PCB with a continuous ground pour under the exposed pad is essential for thermal dissipation.

کاربردهای معمول
PIC32MX150F128DT-V/ML مناسب است برای 6 کاربردs: Automotive HMI and Body Controllers, Industrial Control Panels with Graphic LCD, USB-to-UART and USB Device Bridges, Capacitive Touch Control (mTouch), Low-Cost Audio Processing, Sensor Hub and Data Acquisition.
Automotive HMI and Body Controllers
The PIC32MX150F128DT-V/ML fits automotive HMI and body controllers because its AEC-Q100 V-temp grade (-40C to +105C) and 128 KB Flash support rigorous in-cabin environments. The 40 MHz MIPS32 M4K core at 1.56 DMIPS/MHz runs body-control state machines plus LIN/CAN stacks, while PPS lets engineers remap UART, I2C, and PWM signals to any GPIO to ease PCB routing in cramped dashboards. The 4-channel DMA offloads repetitive peripheral transfers, leaving the CPU free for HMI logic. The 32 KB SRAM accommodates a small RTOS kernel (FreeRTOS PIC32 port) plus graphical buffers, and the 44-pin QFN exposed pad gives solid thermal dissipation behind the instrument cluster.

Industrial Control Panels with Graphic LCD
The PIC32MX150F128DT-V/ML is well suited for industrial control panels with graphic LCDs because the on-chip Parallel Master Port (PMP) drives TFT or monochrome displays directly, eliminating external display controllers. The 128 KB Flash stores graphical assets, fonts, and the control firmware, while the 32 KB SRAM holds double-buffered frame regions. PPS allows the PMP data lines to be assigned to any GPIO, simplifying PCB layout when the LCD connector is fixed. The 40 MHz core refreshes 320x240 QVGA panels at 30+ fps in a typical LVGL-style lightweight GUI, and the V-temp grade ensures operation inside sealed industrial enclosures reaching 80-90C.
پیشنهادی
USB-to-UART and USB Device Bridges
The PIC32MX150F128DT-V/ML serves as a USB-to-UART bridge because the PIC32MX150 family integrates a USB 2.0 Full-Speed device controller (when stepping up to PIC32MX2XX) or pairs with the FTDI-style bit-banged software stack on this F128D variant at 40 MHz. Two UART modules connect to legacy RS-232/RS-485 peripherals, and PPS routes the USB D+/D- pins to convenient package locations. The 128 KB Flash holds USB CDC class drivers and composite-device stacks, while the 32 KB SRAM buffers bulk transfers up to 64-byte EP0 plus 2x 64-byte EP1/EP2 endpoints. The V-temp grade ensures the bridge operates reliably in industrial cabinets without cooling.
پیشنهادی
Capacitive Touch Control (mTouch)
The PIC32MX150F128DT-V/ML supports mTouch capacitive touch buttons and sliders because the on-chip hardware timer with 1 ns resolution measures charge-transfer timing on multiple electrodes without an external touch controller. The 128 KB Flash stores the touch-decision firmware plus general application logic, while the 32 KB SRAM holds per-channel baseline and delta buffers. PPS reassigns the CVD (charge-via-discharge) timing pins to any GPIO, allowing sensors to be placed for ergonomic panel layouts. The 40 MHz MIPS32 M4K core runs 10-20 touch channels at 100 Hz refresh with low CPU overhead, and the V-temp grade supports sealed front panels with internal heating up to +105C.
پیشنهادی
Low-Cost Audio Processing
The PIC32MX150F128DT-V/ML handles low-cost audio processing because the two I2S/SPI modules connect directly to audio DACs (e.g. PCM5101A) and ADCs, while the 128 KB Flash holds audio effects algorithms and small sample buffers. The DMA controller streams audio samples without CPU intervention, freeing MIPS for processing. With 32 KB SRAM the device implements short audio delay lines (ping-pong buffers) plus a small FFT for tone detection. The 40 MHz MIPS32 M4K core runs ~52 MIPS, enough for 16-bit 48 kHz stereo with simple effects. PPS allows the I2S bit-clock and word-select lines to be assigned to any GPIO, easing PCB routing for the audio jack.
پیشنهادی
Sensor Hub and Data Acquisition
The PIC32MX150F128DT-V/ML works as a sensor hub and data acquisition front-end because the two I2C buses connect to multiple digital sensors (temperature, pressure, IMU), while the two UART modules attach GPS or radio modems. The 4-channel hardware DMA streams sensor reads at high rates without CPU load. The on-chip temperature sensor provides local reference data, and the 1 ns hardware timer synchronizes time-stamped samples to within 1 part per million. The 128 KB Flash stores data logging firmware plus sensor calibration tables, while the 32 KB SRAM buffers frames before forwarding them to a host via UART/USB. The V-temp grade supports deployment in automotive sensor clusters and outdoor industrial nodes.

یادداشت‌های طراحی
The PIC32MX150F128DT-V/ML has separate AVDD/AVSS and VDD/VSS pin pairs. Decouple each VDD pin with a 100 nF ceramic capacitor placed within 3 mm of the pin, and add a 4.7 uF bulk capacitor near the package. For ADC accuracy, place a ferrite bead between VDD and AVDD, with a separate 100 nF + 10 uF on AVDD. The 2.3V minimum is for the internal LDO only; below 2.5V the ADC performance degrades by 1-2 LSB.
The 44-pin QFN package has an exposed thermal pad that MUST be soldered to a 4-layer PCB ground pour of at least 25 mm x 25 mm to achieve the rated theta_JA of approximately 28 C/W. Without this pad the junction-to-ambient thermal resistance rises above 60 C/W and the device may thermally throttle at full 40 MHz CPU load. Stencil apertures should be a 4x4 array of 0.4 mm circles on a 1.0 mm pitch to ensure proper solder voiding under 25%.
Route the 40 MHz crystal traces (OSC1/OSC2) as short as possible, keep them over a continuous ground plane, and guard-band them from switching signals with 0.2 mm spacing. The ICSP pins (PGEC1/PGED1 on RB6/RB7) must be accessible in production for in-circuit programming; add a 2x5 1.27 mm header footprint or test pads. PPS reassigns most peripherals, so place the UART, I2C, and SPI connectors based on PCB mechanical constraints and use PPS mappings in firmware to match.
Do not confuse the 'DT' suffix (tape-and-reel, 128 KB Flash) with the 'D' suffix (tray packaging) - both have 128 KB Flash but differ in shipping format. The 'V' suffix is mandatory for AEC-Q100 V-temp automotive (-40C to +105C); 'I' suffix is industrial only (-40C to +85C). PPS mappings are not retained across deep sleep; reconfigure after wake-up. Configuration words (DEVCFG0/1/2/3) MUST be set before code execution - leaving them as default may lock the JTAG or disable the PLL.
Place the external 8 MHz primary crystal within 5 mm of OSC1/OSC2 and route symmetrical trace lengths to maintain duty cycle. If using the internal 8 MHz RC oscillator instead, leave OSC1/OSC2 floating but place a guard ground ring around the pins to reduce noise injection. The VBUS pin (if used) requires a 1 uF capacitor and divider for 5V VBUS sensing on a 3.3V GPIO. Route USB D+/D- as a 90-ohm differential pair with no splits or test points in the middle 80% of the trace length.
