PIC32MX150F128CT-V/TL Обзор
Microcontrollers (MCUs) are programmable semiconductor devices that integrate a CPU core, memory and a rich set of digital and analog peripherals on a single die. The PIC32MX1xx family specifically targets cost-sensitive, USB-enabled embedded applications by combining a 32-bit MIPS core (linear-regulator-class successor to PIC24/dsPIC) with a 5-volt-tolerant I/O ring and a USB PHY, occupying the tier below higher-end PIC32MX3xx/4xx/5xx/6xx/7xx parts.
Key features that differentiate this part include a hardware DMA controller with four channels and automatic data-size detection, two separate PLLs for the CPU and the USB 48 MHz clock, a configurable Watchdog Timer with an on-chip low-power RC oscillator, and multiple low-power modes (Idle, Sleep) that drop quiescent current to microamp levels. The 5-volt-tolerant I/O and Audio/Graphics-compatible PWM/CCP make it well suited for cost-sensitive consumer and industrial Human-Machine Interface boards.
Architecture-wise, the PIC32MX1xx is built on a 32-bit MIPS M4K Harvard architecture featuring separate Flash and SRAM buses, a single-cycle hardware multiplier/divider, and a Prefetch Cache that hides Flash wait states. Compared with the older PIC24/dsPIC families, the M4K core executes most instructions in a single cycle and offers significantly higher code density for C workloads, while remaining code-compatible with the MPLAB XC32 toolchain.
Typical applications include low-cost USB Human Interface Devices (HID), small audio playback devices using PWM or I2S bridges, graphic LCD control panels, low-end embedded WiFi/BLE gateways, and industrial sensor nodes requiring ADC sampling above 250 kHz. The combination of USB-OTG and 12-bit 1 Msps ADC also opens the door to data-acquisition front-ends and USB-CDC virtual COM ports on factory-floor equipment.
When designing with this MCU, note that the VTLA package has an exposed thermal pad that MUST be soldered to the PCB ground plane for proper thermal dissipation and electrical performance. For best USB-2.0 signal integrity, route the D+/D- lines as a 90-ohm differential pair and supply VBUS with a 4.7 uF bulk capacitor per the USB specification.
This page synthesizes distributor pricing, drop-in alternatives within the same PIC32MX1xx family, and practical design notes that go beyond the manufacturer datasheet, giving engineers a single reference for evaluation, sourcing and second-source qualification.

Типичное применение
PIC32MX150F128CT-V/TL подходит для 6 применениеs: USB Human Interface Device (HID), Industrial Sensor Data Logger, Low-Cost Audio Playback Device, Graphic LCD Control Panel, USB CDC Virtual COM Port Device, Automotive Body Electronics Node.
USB Human Interface Device (HID)
The PIC32MX150F128CT-V/M4L integrates a USB 2.0 Full-Speed OTG PHY plus a 32 KB SRAM buffer that comfortably hosts HID report buffers and MPLAB Harmony HID stacks. With 128 KB of Flash the device can run composite HID (keyboard + mouse + consumer control) stacks and a small RTOS without external memory. The 40 MHz MIPS M4K core delivers enough headroom for 1000 Hz polling rates, while the dedicated USB PLL supplies the 48 MHz USB clock without burdening the system PLL. Place a 4.7 uF VBUS bulk capacitor and route D+ versus D- as a 90-ohm differential pair for full USB compliance.

Industrial Sensor Data Logger
With a 10-bit 1 Msps ADC and up to 12 analog input channels, the PIC32MX150F128CT-V/M4L can sample multiple analog inputs at high sample rates for legacy industrial front-ends. The 32 KB SRAM holds sizeable data buffers while the 4-channel DMA controller streams ADC conversions into memory without CPU intervention. The four DMA channels support automatic data-size detection, simplifying chained ADC-to-UART transfers. Combined with the AEC-Q100 V temperature grade (-40C to +105C) the part fits factory-floor and outdoor instrumentation deployments.
Рекомендуется
Low-Cost Audio Playback Device
The PIC32MX150F128CT-V/M4L PWM/CCP peripherals plus 32 KB of SRAM make it suitable for low-bitrate audio playback via PWM-to-analog low-pass-filtered output, or for I2S bridging to an external DAC. The 40 MHz MIPS M4K core comfortably decodes 16 kHz ADPCM or 22 kHz WAV samples, while the VQFN/VTLA footprint suits compact handheld or wearable designs. Five 16-bit timers support independent sample-rate generation and DMA-assisted audio streaming. For higher-fidelity output, pair the MCU with an external I2S DAC such as the MCP4725 or PCM5101A.
Рекомендуется
Graphic LCD Control Panel
The PIC32MX150F128CT-V/M4L drives small graphic LCDs and OLED panels through SPI or 8-bit parallel interfaces thanks to its 21 I/O pins and PPS remapping. The 40 MHz MIPS core renders text and simple graphics in real time at typical 128x64 monochrome resolutions, while the DMA controllers offload SPI transfers to free the CPU for UI logic. The 128 KB Flash stores font tables and UI bitmaps, and the AEC-Q100 V temperature grade supports outdoor display modules with full sunlight-temperature operation.
Рекомендуется
USB CDC Virtual COM Port Device
Using the on-chip USB 2.0 Full-Speed OTG plus the Microchip MPLAB Harmony CDC stack, the PIC32MX150F128CT-V/M4L acts as a USB-to-UART bridge for firmware updates, sensor data streaming or factory diagnostic ports. The 32 KB SRAM hosts USB endpoint buffers and a small UART ring buffer simultaneously. Two UART peripherals allow concurrent bridged serial streams, while PPS remapping routes debug UART to any free pin during development. The result is a single-chip bill-of-materials for both legacy RS-232 and modern USB-CDC tools.
Рекомендуется
Automotive Body Electronics Node
The PIC32MX150F128CT-V/M4L V temperature suffix qualifies it for AEC-Q100 automotive use, making it a fit for body electronics modules such as HVAC door modules, mirror controllers and seat-position nodes that require up to 105C operation. The 32 KB SRAM supports LIN and CAN software stacks with comfortable headroom, while the 12 ADC channels read multiple sensor inputs. For full CAN bus integration pair the MCU with an external MCP2551 CAN transceiver, or use the PIC32MX1xx LIN-capable peripherals directly for cost-sensitive LIN sub-nodes.

Заметки по проектированию
The 36-pin VTLA package has an exposed thermal pad (pin 36 in the pinout list) that MUST be soldered to a PCB ground plane. For reliable operation at 40 MHz with USB active, design at least 1 square inch (645 mm^2) of copper pours on the top layer connected to the exposed pad, with thermal vias to the inner ground plane. Estimated: at maximum core activity and VDD = 3.3V, the part dissipates approximately 100 mW; without a proper thermal pad, junction temperature may rise 25-30 C above ambient.
USB-2.0 Full-Speed compliance requires the D+ and D- lines be routed as a 90-ohm differential pair, matched to within 150 mils of length difference. Place the 4.7 uF VBUS bulk capacitor within 5 mm of pin 28/VVBUS. The VUSB pin (pin 11) requires an external 4.7 uF decoupling capacitor to filter the internal 3.3V LDO output. Avoid routing digital signals across the differential pair; if crossing is unavoidable, do so at 90 degrees.
Place the 0.1 uF VDD decoupling capacitors within 2 mm of each VDD pin (pins 14 and 33), and add a bulk 10 uF tantalum or ceramic capacitor on the same VDD rail. Connect all VSS pins (5, 20, 32) to a single continuous ground pour. Avoid routing high-frequency signals (USB, SPI clocks) parallel to analog input traces to minimize crosstalk into ADC readings.
Common pitfalls include: (1) forgetting the exposed pad solder connection, which leads to erratic behavior at 40 MHz; (2) failing to enable the on-chip FRC postscaler before switching the system clock, causing code lockup; (3) omitting the VUSB decoupling capacitor, leading to USB enumeration failures; (4) using the V (A105C) part on a VDD rail above 3.6V, which violates the absolute maximum rating. Always verify the toolchain configuration uses the FLY/MX1xx device family header.
The 10-bit ADC achieves 1 Msps only when the acquisition time and conversion clock are properly configured. Use the Peripheral Pin Select (PPS) module to assign analog functions and ensure the selected analog pin is not driven by a digital output simultaneously. For multi-channel scanning, enable the DMA controller to offload ADC result transfers and prevent sample loss at high conversion rates.
