PIC32MX150F128BT-V/SO Descripción general
A PIC32MX-series microcontroller is a 32-bit RISC MCU built on the MIPS microAptiv (M4K) core, sitting in Microchip's hierarchy of 32-bit embedded controllers: PIC32MX -> PIC32 -> 32-bit MCU -> microcontroller -> semiconductor. Compared with 8-bit PIC16/PIC18 devices, the PIC32MX delivers deterministic interrupt latency, full C-language efficiency, and on-chip peripherals that previously needed glue logic - making it a mainstream choice for human-machine interface (HMI), audio decoding, and USB device applications.
Key features include two I2S/SPI interfaces for codec and serial communications, Peripheral Pin Select (PPS) for flexible signal routing, mTouch capacitive touch buttons and sliders, on-chip temperature measurement, and a Parallel Master Port for graphics interfaces. Hardware trace and JTAG boundary-scan interfaces support development, and the wide-body 28-SOIC footprint is friendly to through-hole DPCB prototypes and hand-rework designs.
The device uses a Harvard-architecture bus with separate program Flash (128 KB) and data SRAM (32 KB) for deterministic code-fetch and zero-wait-state operation up to 40 MHz. Integrated DMA, up to 5 timers, PMP, I2S/SPI, USB, and ADC peripherals enable designers to consolidate multiple external components onto a single chip, reducing BOM cost and PCB area. Less than 0.5 mA/MHz active current keeps thermal dissipation low in compact sealed enclosures.
Typical applications include USB audio bridges, capacitive touch human-machine interfaces, graphic LCD control via PMP, low-cost sensor data acquisition, and industrial control panels. The V-temp range and automotive pedigree make the -V/SO grade especially suited for AEC-Q100 design chains and automotive-grade subsystems where higher temperature reliability is required.
When designing with the PIC32MX150F128BT-V/SO, confirm that your toolchain - MPLAB X IDE, XC32 compiler, and Harmony framework - supports the exact silicon revision (B revision). Route analog inputs away from PWM outputs to minimize ADC crosstalk, and use 100 nF + 10 uF decoupling close to each VDD/VSS pair. Boundary-scan is enabled through dedicated JTAG pins for in-circuit test coverage.

Aplicaciones típicas
PIC32MX150F128BT-V/SO es adecuado para 6 aplicacións: USB Audio Bridge (USB-I2S DAC), Capacitive Touch HMI Panel, Industrial Sensor Data Acquisition, Low-Cost Graphic LCD Controller, Automotive Interior Control Module, USB HID / Composite Device.
USB Audio Bridge (USB-I2S DAC)
The PIC32MX150F128BT-V/SO's integrated USB 2.0 full-speed device controller plus two I2S/SPI interfaces implement a low-cost USB audio bridge (UAC1) at 44.1 kHz and 48 kHz sample rates. 32 KB of SRAM buffers multiple USB packets and I2S audio frames concurrently, while the MIPS M4K core at 40 MHz runs USB descriptors, class drivers, and I2S transmit with low interrupt latency. Unlike external USB+I2S controller pairs, the integrated solution cuts BOM count, eliminates board-level digital glue, and runs under 0.5 mA/MHz for low-power bus-powered designs. Common pairings include S/PDIF transmitter, headphone amplifiers, and external DACs such as PCM5102A.
Recomendado
Capacitive Touch HMI Panel
mTouch capacitive touch hardware plus the Parallel Master Port (PMP) make the PIC32MX150F128BT-V/SO a fit for human-machine interface panels with capacitive buttons, sliders, and graphic LCDs. The dedicated touch sensing peripheral offloads scan timing from the CPU, while PMP drives 320x240 or 480x272 graphical LCDs without external controller logic. 32 KB SRAM holds framebuffer slices for partial updates, and the 1 ns resolution time-capture unit precisely measures touch gestures. The V-temp grade supports under-dash and outdoor industrial panels where temperature exceeds 85C.
Recomendado
Industrial Sensor Data Acquisition
The PIC32MX150F128BT-V/SO's 10-bit 1 Msps ADC, DMA controller, and five 16-bit timers address multi-channel sensor acquisition in industrial automation. Hardware DMA streams ADC conversions into SRAM without CPU intervention, freeing the MIPS M4K core to run protocol stacks (Modbus, CAN) and user application logic. The 21 GPIO accept multiple sensors - temperature (RTD, thermocouple), pressure, flow - and the V-temp range supports factory-floor ambient and equipment-cabinet environments. < 0.5 mA/MHz active current keeps embedded sensor modules thermally stable.
Recomendado
Low-Cost Graphic LCD Controller
The PIC32MX150F128BT-V/SO's PMP peripheral directly drives monochrome and small color TFT LCDs (e.g. 128x64, 320x240) without external graphics controller, eliminating the cost of a dedicated LCD controller IC. The MIPS M4K core at 40 MHz handles text rendering, basic animations, and user-interface state machines. 128 KB Flash stores multilingual fonts and graphic assets, while 32 KB SRAM accommodates framebuffer slices for double-buffered partial screen updates. The 28-SOIC package is well-suited for hand-soldered prototypes and small-batch industrial products.
Recomendado
Automotive Interior Control Module
AEC-Q100 design chains targeting interior cabin electronics - HVAC control, seat controller, lighting - leverage the PIC32MX150F128BT-V/SO V-temp grade (-40C to +105C) and Microchip's automotive pedigree. 21 GPIO drive switches, LEDs, and LIN slaves; integrated mTouch adds capacitive touch to modern interior buttons; and USB supports diagnostics and media connectivity. < 0.5 mA/MHz active current supports tight standby power budgets for always-on body controllers. The 28-SOIC footprint handles automotive vibration and thermal-cycling stress.
Recomendado
USB HID / Composite Device
The integrated USB 2.0 full-speed device on PIC32MX150F128BT-V/SO supports HID, CDC (virtual COM port), and composite device classes with minimal external components. The MIPS M4K core handles HID report generation, command parsing, and indicator LEDs, while 32 KB SRAM buffers HID reports and CDC ACM data. The 28-SOIC wide-body package simplifies prototyping on perfboard and hand-rework of small-volume products. Microchip's free USB stack (MLA / Harmony) provides ready-to-customize HID and CDC class drivers for embedded human-interface devices.

Notas de diseño
Place a 100 nF decoupling capacitor close to each VDD/VSS pair (pins 7/6, 13/12, 19/18) and add a bulk 10 uF ceramic near the highest VDD pin. The PIC32MX150F128BT-V/SO draws < 0.5 mA/MHz active current, but the 5V-tolerant I/O pins do not exist on this 3.3 V part - never drive any pin above VDD+0.3 V or below VSS-0.3 V, or latchup may occur. Use the on-chip voltage regulator (VDDCORE pin internal) by tying all VDD pins together and providing sufficient bulk capacitance.
Route analog inputs (AN0-AN15) away from PWM outputs and digital switching signals to minimize ADC crosstalk. Use a ground plane under the device for analog return paths, and place the analog reference capacitor (if used) within 0.5 inch of the AVDD pin. The wide-body 28-SOIC footprint leaves adequate room for ground-plane flooding and power-trace routing on two-layer PCBs without sacrificing signal integrity for USB or PMP signals.
Do not enable JTAG boundary-scan unless you dedicate TMS/TCK/TDO/TDI pins to JTAG - boundary scan can conflict with GPIO and remappable peripheral routing. The PPS (Peripheral Pin Select) feature lets remappable peripherals move to specific GPIO pins, but PPS lock registers must be cleared in the unlock sequence before reprogramming. Ensure your MPLAB X IDE and XC32 compiler configuration matches the silicon B revision; legacy PIC32MX1xx code may need a register-name update for silicon rev B.
