PIC32MX150F128DT-50I/PT Descripción general
An MCU (Microcontroller Unit) is a single-chip computer containing a CPU core, program and data memory, plus integrated peripherals such as ADC, timers, and communication interfaces. The PIC32MX family is part of the broader 32-bit microcontroller category, which itself sits within embedded processing and semiconductor ICs. Microchip's PIC32MX1xx/2xx/3xx/4xx family targets cost-sensitive, low-power embedded applications requiring DSP-like MIPS performance at low active current below 0.5 mA/MHz.
Key features include Peripheral Pin Select (PPS) for flexible I/O mapping, five 16-bit timers, two comparators, two UARTs, and hardware mTouch capacitive touch support. The integrated 1.6 ns resolution timer captures high-speed events. The 50 MHz core delivers 50 MIPS, while the dedicated DMA engine offloads data movement between peripherals and memory, freeing the CPU for application code.
The architecture combines a MIPS32 M4K core with Harvard-style bus topology, on-chip voltage regulation, and JTAG/ICSP debug. USB 2.0 full-speed with on-chip transceiver eliminates external PHY cost for HID, CDC, and basic device-class applications. PMP supports direct LCD/glucose-display parallel interfaces common in medical and industrial HMI designs.
Typical applications include USB peripherals, industrial control panels with PMP-driven LCDs, audio playback using I2S codecs, capacitive touch user interfaces, sensor hubs with DMA-driven ADC acquisition, and low-power consumer devices requiring deterministic real-time response. The compact 10x10 mm TQFP and integrated USB simplify PCB layout and BOM cost.
When designing with this device, ensure VDD decoupling uses 100 nF ceramic capacitors within 5 mm of each VDD/VSS pair, and that the 8 MHz internal oscillator is configured for the active system clock. Leave unused pins configured as outputs low to minimize current draw.

Aplicaciones típicas
PIC32MX150F128DT-50I/PT es adecuado para 6 aplicacións: USB HID Peripheral Device, Industrial PMP-Driven LCD HMI, Audio Playback with I2S Codec, Capacitive Touch User Interface, Sensor Hub with DMA ADC Acquisition, Low-Power Consumer Remote Control.
USB HID Peripheral Device
The PIC32MX150F128DT-50I/PT fits USB HID peripheral designs because its on-chip USB 2.0 Full-Speed transceiver with internal pull-up eliminates the external PHY. The 128 KB Flash accommodates USB stacks plus HID report descriptors, and the 32 KB SRAM buffers HID data plus application variables. At 50 MHz, the MIPS M4K core handles 1 ms USB polling frames with significant headroom for HID report processing, while PPS allows flexible mapping of D+/D- and USB-related interrupts to any GPIO, simplifying PCB routing on compact peripherals.
Recomendado
Industrial PMP-Driven LCD HMI
The PIC32MX150F128DT-50I/PT is well suited for industrial HMI panels that drive small character or graphic LCDs via its Parallel Master Port (PMP). The PMP supports 8-bit data plus dedicated control lines to address common LCD controllers, offloading the CPU from bit-banged timing. The 50 MIPS performance combined with DMA keeps touch-scan and display-refresh cycles deterministic at 60 Hz, while the -40 to +85 C industrial temperature range ensures operation in factory-floor environments. The 34 GPIO count is sufficient for keypad matrix plus display control.
Recomendado
Audio Playback with I2S Codec
The PIC32MX150F128DT-50I/PT supports I2S audio playback via its two I2S/SPI modules, suitable for compressed audio stream decoding into an external DAC. The 128 KB Flash stores audio codec tables plus application code, and the 32 KB SRAM provides a small frame buffer for short clips. DMA-driven I2S transfers eliminate CPU intervention during playback, allowing low-power standby between audio events. The 50 MHz core decodes MP3 or ADPCM at low bitrates in real time without dropping samples.
Recomendado
Capacitive Touch User Interface
The PIC32MX150F128DT-50I/PT integrates mTouch capacitive touch hardware with support for buttons, sliders, and proximity sensors without external components. Its high-resolution 1.6 ns timer captures charge-cycle timing for stable touch measurements in noisy industrial environments. Combined with DMA-driven ADC scanning, the 50 MIPS performance handles 20+ touch channels at 100 Hz refresh, suitable for white goods, lighting controls, and consumer touch panels. PPS allows touch channels to be remapped to any GPIO, simplifying PCB sensor layout.
Recomendado
Sensor Hub with DMA ADC Acquisition
The PIC32MX150F128DT-50I/PT serves as a sensor hub that aggregates multi-channel analog sensor data via its 10-bit 13-channel ADC, with DMA moving conversion results directly into memory without CPU overhead. The 32 KB SRAM buffers full sample frames before periodic USB or UART transmission to a host controller. At 50 MHz, the MIPS core handles filter calculations, peak detection, and thresholding in real time. PPS allows flexible ADC trigger routing for synchronized multi-sensor sampling.
Recomendado
Low-Power Consumer Remote Control
The PIC32MX150F128DT-50I/PT fits battery-powered consumer remote controls because its MIPS32 M4K core draws less than 0.5 mA/MHz active and supports multiple low-power sleep modes for idle operation. The 128 KB Flash accommodates IR/RF protocol libraries plus user interface code, and the 32 KB SRAM supports on-screen menu rendering for OLED displays. USB-CDC allows field firmware upgrades via standard USB cables, while mTouch enables capacitive button arrays without mechanical switches.

Notas de diseño
Place a 100 nF 0402 ceramic decoupling capacitor within 5 mm of each VDD/VSS pin pair (pins 19/20, 30/31, plus the VDD core pair). For USB applications, add a 10 uF bulk capacitor near VUSB pin 27 to stabilize the internal 3.3V USB regulator. The total quiescent current draw rises significantly with un-decoupled VDD traces, so keep VDD traces short and use a ground pour on the layer directly under the TQFP body.
The 44-pin TQFP package has a typical θJA around 50 C/W on a standard 4-layer JEDEC test board. At full 50 MHz active load, total power consumption is approximately 25 mA active (0.5 mA/MHz typical), giving a junction rise of roughly 1.3 C above ambient. The industrial -40 to +85 C rating ensures operation across most factory environments without active cooling, but derate by 10 C in enclosed housings with no airflow.
Use a continuous ground pour on the top layer beneath the TQFP body, stitched to the bottom ground plane with 8-12 vias arranged around the package perimeter. Route the 50 MHz system clock (primary or secondary oscillator) trace using 50 Ω controlled impedance, length-matched with the complementary clock trace. Keep USB D+/D- differential pair matched within 150 mil length difference and route over a continuous ground reference plane.
Per Microchip errata for early PIC32MX1xx revisions, JTAG PGED1/PGEC1 pins (RB0/RB1 on this TQFP) must be pulled low during reset if not used, or the device may enter an unexpected debug state. Always configure all unused GPIO as outputs driving low to minimize current draw, and verify PPS remapping conflicts using the MPLAB X IDE Pin Manager before board fabrication. Do not enable the on-chip USB regulator's VUSB pin 27 with a capacitor less than 1 uF, as this causes unstable USB bus signaling.
For PMP-driven LCD interfaces, add 33 Ω series damping resistors on each of the 8 data lines and 3 control lines (RD, WR, CS) within 25 mm of the MCU. This suppresses overshoot caused by cable capacitance in long FPC connections to display modules. For I2S audio applications, keep the MCLK-to-LRCLK ratio deterministic by using a fixed peripheral bus clock and avoid dynamic clock switching during active audio playback.
