PIC32MX150F256H-V/PT Overview
A 32-bit microcontroller is an integrated circuit that combines a 32-bit CPU core, program memory (Flash), data memory (SRAM), and multiple peripherals (timers, communication interfaces, ADCs) on a single silicon die. Within the broader taxonomy, the PIC32MX sits in the PIC32 family of MIPS-based MCUs, which itself belongs to the Microchip 8/16/32-bit MCU portfolio, ultimately classified as a microcontroller IC under semiconductors. The M4K core executes most instructions in a single cycle, giving the PIC32MX150F256H its 1.56 DMIPS/MHz figure and enabling efficient C code execution.
Key differentiating features include Peripheral Pin Select (PPS), which allows remapping of digital peripheral I/O onto a wide set of pins, simplifying PCB layout. The PMP module with dual buffers accelerates graphics and external memory interfacing, while the CTMU and mTouch support enable capacitive touch sensing without an external touch controller. The integrated 10-bit ADC and multiple I2S/SPI channels support audio codec bridging and sensor data acquisition.
Architecturally, the PIC32MX150F256H combines Harvard bus architecture (separate Flash and SRAM buses) with a 5-stage pipeline M4K core, achieving 83 DMIPS at 50 MHz while retaining low active current draw typical of PIC MCUs. This makes the device suitable for low-power embedded designs that need 32-bit headroom.
Typical applications include industrial control panels with touch HMI, audio playback/recording with external codecs, low-cost graphics interfaces via PMP, USB device/host stacks (with external transceiver), and connected sensor nodes. When designing with this part, ensure the 2.5 V or 3.3 V core/IO rails are decoupled with 100 nF + bulk caps, and use PPS strategically to avoid pinout conflicts when migrating between PIC32MX1XX/2XX/5XX family members.

Typical Applications
PIC32MX150F256H-V/PT is suitable for 6 applications: Industrial Touch HMI Controller, Audio Codec Bridge (I2S), USB Device / Embedded Host, Low-Cost Graphics Interface via PMP, Connected Sensor Node / IoT Edge, Automotive Aftermarket / Body Electronics.
Industrial Touch HMI Controller
The PIC32MX150F256H-V/PT suits industrial touch HMI panels because its CTMU and mTouch peripherals enable up to 32 capacitive touch channels without an external touch IC, saving BOM cost. The PMP module with dual read/write buffers drives TFT displays via external controller or direct 8/16-bit bus, while PPS remaps I/O to simplify routing of touch and display lines on a 4-layer PCB. At 50 MHz/83 DMIPS, the M4K core runs a graphics object library and refreshes a QVGA panel while polling touch sensors at 100 Hz, with ample headroom for debounce and gesture recognition. Per Microchip application notes, 32 KB SRAM buffers a QVGA frame in indexed color, and 256 KB Flash holds the full UI library, bootloader, and USB DFU update image.
Recommended
Audio Codec Bridge (I2S)
The PIC32MX150F256H-V/PT integrates two I2S modules plus four SPI, allowing simultaneous connection to an audio codec and a Bluetooth/USB audio front-end. Its 50 MHz MIPS32 M4K core sustains real-time sample-rate conversion and mixing at 48 kHz/24-bit with low CPU overhead, while 32 KB SRAM buffers 100 ms of stereo audio without DMA contention. Per Microchip PIC32MX audio reference designs, the DMA controller can service I2S streams independently of the CPU, leaving the M4K free for DSP-style filtering. Compared to an 8-bit MCU, the 32-bit core executes volume control and EQ algorithms with far greater dynamic range, and the 256 KB Flash holds a full audio stack plus firmware updates.
Recommended
USB Device / Embedded Host
With 256 KB Flash and 32 KB SRAM, the PIC32MX150F256H-V/PT comfortably runs the Microchip USB stack (device, host, or OTG) along with application logic on the M4K core at 50 MHz. The integrated USB 2.0 full-speed peripheral and DMA support allow external transceiver interfacing for low-speed applications like HID, CDC, and MSD classes. PPS allows flexible assignment of USB D+/D- to GPIO pins on the TQFP-64 footprint, simplifying PCB layout. The wider -40C to +105C (V grade) operating range supports industrial USB peripherals and outdoor instrumentation where consumer-grade parts overheat, and Microchip provides free USB stack firmware with example HID/CDC projects for fast development.
Recommended
Low-Cost Graphics Interface via PMP
The PIC32MX150F256H-V/PT features a Parallel Master Port (PMP) with dual read/write buffers, enabling direct 8/16-bit parallel interfacing to TFT controllers or external SRAM. The 50 MHz MIPS32 M4K core can refresh a QVGA display at 30 Hz while leaving cycles for graphics rasterization in firmware. The dual PMP buffers reduce CPU stalls during consecutive read/write cycles, which is critical for smooth animations. Compared to SPI-only MCUs, the parallel PMP path achieves 5-10x higher throughput, allowing higher color depth or larger panels. Designers commonly pair this part with SSD1963 or ILI9341 controllers, using the 32 KB SRAM as a graphics scratch buffer.
Recommended
Connected Sensor Node / IoT Edge
With 4 SPI and 2 I2S plus I2C and UART peripherals, the PIC32MX150F256H-V/PT can interface with multiple sensors (accelerometer, temperature, pressure, MEMS microphone) while running edge processing algorithms on its 32-bit M4K core. The PPS feature allows flexible remapping of sensor-bus pins, simplifying layout for compact sensor boards. At 50 MHz, the MCU can execute sensor fusion at sub-millisecond latency with deterministic interrupt response thanks to the M4K pipeline. The V-grade -40C to +105C range suits outdoor IoT deployments and industrial sensor hubs, while the 256 KB Flash holds complete wireless stacks (e.g., LoRaWAN, ZigBee) plus custom edge logic.
Recommended
Automotive Aftermarket / Body Electronics
Although not AEC-Q100 qualified, the PIC32MX150F256H-V/PT's -40C to +105C operating range and 50 MHz MIPS32 performance make it suitable for aftermarket automotive modules: CAN-bus bridges, lighting controllers, dashboard accessories, and HVAC peripherals. The 4 SPI ports support multi-channel LED drivers and motor controllers, while the PMP module interfaces to alphanumeric or graphic LCDs. Compared to 8-bit MCUs, the 32-bit core handles OBD-II parsing, real-time CAN message scheduling, and security firmware with substantially more headroom. Designers typically pair this MCU with external CAN transceivers (e.g., MCP2551) and step-down regulators, using the 256 KB Flash to store vehicle-protocol libraries.

Design Notes
Decouple the PIC32MX150F256H-V/PT with a 100 nF ceramic capacitor placed within 5 mm of every VDD/VSS pin pair, plus a single 4.7 uF or 10 uF bulk capacitor near the device. The 64-pin TQFP has multiple VDD pins (pins 5, 23, 44, 64); each requires its own 100 nF bypass. The VCAP pin (42) needs a 10 uF low-ESR capacitor to stabilize the internal 1.8 V core regulator. Per Microchip PIC32MX datasheet, operating the part from a switching regulator without adequate LC filtering can inject noise into the ADC and CTMU analog blocks; use an LDO or post-filter when analog accuracy matters.
The TQFP-64 (10x10 mm) package has a 0.5 mm pitch and a thermal pad (center pad) on the underside; Microchip recommends connecting this center pad to a copper pour tied to ground for thermal dissipation and mechanical stability. Route analog signals (ADC, CTMU) away from switching nodes and high-current traces, and place a guard ring around the AVSS/AVDD pair. The JTAG pins (TCK/TMS/TDI/TDO) are shared with general-purpose I/O on PORTB; if JTAG is not used, configure these as GPIO via the config bits. Crystal traces (OSC1/OSC2) should be short and guarded with ground to minimize EMI.
Three common pitfalls when designing with PIC32MX150F256H-V/PT: (1) forgetting to connect the MCLR pull-up resistor (10 kohm typical) causes intermittent resets; (2) leaving the JTAG pins in their default configuration interferes with shared GPIO functions - disable JTAG via config bits if unused; (3) using a 3.3 V supply but assuming 5 V-tolerant I/O is unsafe - the PIC32MX150F256H-V/PT I/O are NOT 5 V tolerant; add series resistors or level shifters when interfacing with 5 V logic. Per Microchip datasheet errata, also confirm the VCAP capacitor ESR is below 1 ohm to avoid core regulator instability.
Compliance Information
