A 32-bit microcontroller (MCU) is an integrated circuit that combines a high-performance processor core, program memory (Flash), data memory (SRAM), and a configurable set of peripherals on a single die. PIC32MX devices sit within Microchip's PIC32 family, targeting applications that need more computational headroom and richer peripherals than 8-bit PIC MCUs while retaining the familiar MPLAB X toolchain. The M4K core executes most instructions in a single cycle and supports DSP extensions.
Key specifications include 128 KB (128K x 8) Flash, 32 KB SRAM, 21 general-purpose I/O lines (some sources cite up to 34 GPIOs depending on multiplexing), five 16-bit timers, a 16-bit Input Capture, a 16-bit Output Compare/PWM, and an on-chip temperature sensor. The device runs from 2.3 V to 3.6 V and supports an industrial temperature range of -40 °C to +105 °C. Pin-to-pin compatible siblings in the VTLA-44 package range from 64 KB up to 256 KB Flash.
Architecturally, the PIC32MX150F128D uses a 5-stage pipeline MIPS32 M4K core, separate 32-bit instruction and data buses, and dedicated peripherals reachable via PPS remapping for flexible PCB routing. The integrated USB 2.0 full-speed device controller, combined with audio (I2S) and graphics (PMP) interfaces, makes it well suited for connected multimedia and human-machine interface (HMI) nodes.
Typical applications include USB audio peripherals, low-cost HMI boards with TFT panels, capacitive-touch user interfaces using mTouch, industrial control nodes with USB diagnostics, and consumer graphics accessories. The wide peripheral mix and USB support let one chip replace a discrete MCU plus external controller.
When designing with this part, verify the I/O count and PPS mapping for your specific signal layout - VTLA-44 exposes fewer pins than TQFP-44. Plan for a 2.3-3.6 V supply with adequate bulk decoupling near VDD/VSS pairs, and use MPLAB X with XC32 for firmware development.
This page synthesizes distributor pricing, pin-compatible alternatives in the same VTLA-44 footprint, and practical design notes that go beyond the manufacturer datasheet.

典型應用
PIC32MX150F128DT-I/TL 適用於 6 應用s: USB Audio Peripherals, Human-Machine Interface (HMI) Boards, Capacitive Touch User Interfaces (mTouch), Industrial Control Nodes with USB Diagnostics, Consumer Graphics and LED Controllers, Portable Data Acquisition Modules.
USB Audio Peripherals
The PIC32MX150F128DT-I/TL is well matched to USB audio peripherals thanks to its integrated USB 2.0 full-speed device controller and two I2S/SPI modules that connect directly to external audio codecs. Its 32 KB SRAM accommodates small USB audio packet buffers, while the 40 MHz M4K core handles USB protocol plus audio streaming without offloading. The 2.3-3.6 V supply range also aligns with 3.3 V codec rails, simplifying power tree design in low-cost USB headsets and DAC dongles.
推薦
Human-Machine Interface (HMI) Boards
The PIC32MX150F128DT-I/TL drives small TFT LCDs and capacitive touch panels through its Parallel Master Port (PMP) and mTouch peripheral. The PMP supports 8-bit parallel data plus control lines, suiting common 3.5-inch TFT modules. With 128 KB Flash and PPS remappable I/O, the MCU can host a graphics library plus a USB diagnostic channel. Designers can replace a separate LCD controller IC with this single chip at modest BOM cost.
推薦
Capacitive Touch User Interfaces (mTouch)
The PIC32MX150F128DT-I/TL natively supports Microchip's mTouch capacitive touch sensing through the on-chip Charge Time Measurement Unit (CTMU), enabling sliders, buttons, and proximity sensors without an external touch IC. The CTMU works with PPS-mappable I/O, allowing capacitive channels to be reassigned across spare pins. Combined with USB, designers can build low-cost touch panels that report over USB HID to a host PC.
推薦
Industrial Control Nodes with USB Diagnostics
The PIC32MX150F128DT-I/TL fits industrial 24 V down-converted 3.3 V systems where USB diagnostics, sensor conditioning, and a small HMI co-exist. Its -40 to +105 °C industrial temperature range covers most factory-floor enclosures, and its 10-bit ADC at up to 1 Msps handles transducer sampling. The on-chip temperature sensor also simplifies enclosure thermal monitoring without an external diode.
推薦
Consumer Graphics and LED Controllers
The PIC32MX150F128DT-I/TL drives addressable LED strings and small OLED/TFT displays through PWM plus I2S or SPI. Its 16-bit Output Compare/PWM and 5x 16-bit timers provide ample PWM channels for RGB lighting without an external driver. The USB interface allows firmware updates and DMX-style control from a host computer, making it a flexible building block for hobbyist and prosumer lighting fixtures.
推薦
Portable Data Acquisition Modules
The PIC32MX150F128DT-I/TL is suitable for portable data acquisition thanks to its 10-bit 1 Msps ADC, USB power and data, and compact VTLA-44 (6x6 mm) footprint. Battery-powered designs benefit from the MCU's low-power Run and Idle modes plus peripheral disable registers for sub-mW standby. The combination of small size, USB charging interface, and on-chip temperature sensor suits handheld loggers that stream data to a laptop over USB CDC.

主要差異化特點
- Compact VTLA-44 footprint enables smaller PCB designs than TQFP-44 siblings (對比PIC32MX150F128DT-I/PT (TQFP-44 10x10 mm))
- Higher memory density for larger framebuffers and USB stacks (對比PIC32MX150F128DT-50I/TL)
- Lower cost option with identical peripherals for cost-sensitive designs (對比PIC32MX150F128C-50I/TL (50 MHz revision C))
設計說明
Provide a bulk 10 µF ceramic or tantalum capacitor plus a 0.1 µF decoupling capacitor on every VDD/VSS pair of the PIC32MX150F128DT-I/TL. Place the 0.1 µF cap within 2-3 mm of the supply pins to suppress switching transients during USB packet transmission. For USB bus-powered designs, add 10 µF on VBUS and a ferrite bead to isolate analog VDD from digital switching noise.
Route the USB D+ and D+ lines as a 90 Ω differential pair with matched length to within 2 mm, and keep them away from high-frequency switching signals. The VTLA-44 (6x6 mm) package has a small thermal pad underneath; connect it to a copper pour to keep the M4K core within the -40 to +105 °C industrial range during sustained USB activity. Avoid placing the IC near I2S MCLK traces to minimize coupled jitter.
Do not exceed the 3.6 V absolute maximum on VDD - even brief over-voltage during USB hot-plug can latch-up the PIC32MX150F128DT-I/TL. Configure unused I/O as outputs low (not inputs floating) to minimize supply current. When migrating firmware from a PIC32MX1XX to PIC32MX2XX sibling, check the PPS input/output mapping table; some peripherals shift to different RPn pins. Verify the VBUSON function is enabled in firmware before relying on USB host detection.
