PIC32MX150F128D-I/TL Overview
A 32-bit microcontroller (MCU) is a programmable processor that integrates CPU core, memory and peripherals on a single die, executing instructions of 32-bit width for higher throughput than 8/16-bit MCUs. PIC32MX devices belong to the PIC32 family within Microchip's broader microcontroller hierarchy (MCU -> 32-bit MCU -> MIPS-based MCU -> PIC32MX -> PIC32MX150 series), targeting low-power connected and embedded applications with USB, audio and graphics interfaces.
Key features of the PIC32MX150F128D-I/TL include 128 KB flash program memory, 32 KB SRAM, 40 MHz maximum CPU clock, two I2S/SPI modules, Peripheral Pin Select (PPS), Parallel Master Port (PMP) for graphics, a 10-bit 1 Msps ADC with up to 28 channels, four 16-bit timers, two comparators and a Charge Time Measurement Unit (CTMU) for capacitive touch or 1 ns time measurement. The MIPS32 M4K core delivers less than 0.5 mA/MHz active current, supporting battery-sensitive designs.
The architecture combines a Harvard-style bus with tightly-coupled peripherals, deterministic interrupt latency and hardware DMA. Operating from 2.3V to 3.6V across -40 C to +105 C, it integrates USB 2.0 full-speed device/host/OTG, I2C, UART, SPI and PMP for richer connectivity than smaller-pin PIC32MX1xx variants.
Typical applications include USB peripherals, audio interfaces with I2S codecs, low-cost graphics HMI with PMP, capacitive-touch keypads using CTMU, industrial control nodes and consumer devices requiring USB connectivity in a compact 44-pin footprint.
Designers should plan PPS remapping to assign digital functions to physical pins without PCB rework. Use MPLAB X IDE with XC32 compiler and Harmony framework for firmware development.

Typical Applications
PIC32MX150F128D-I/TL is suitable for 6 applications: USB Peripherals and HID Devices, Audio Interfaces with I2S Codecs, Low-Cost Graphics HMI with PMP, Capacitive Touch Keypads with CTMU, Industrial Control Nodes, Consumer Devices with USB Connectivity.
USB Peripherals and HID Devices
The PIC32MX150F128D-I/TL is engineered for USB peripherals thanks to its integrated USB 2.0 full-speed device/host/OTG controller with on-chip transceiver, eliminating the need for external USB PHY chips. The 40 MHz MIPS32 M4K core provides the throughput required for HID, CDC, MSD or custom USB class stacks while keeping MIPS/USB-IF interrupt latency low. The 128 KB flash fits typical USB stacks with descriptors, and the 32 KB SRAM buffers endpoint data without DMA pressure.
Recommended
Audio Interfaces with I2S Codecs
Two I2S/SPI modules make the PIC32MX150F128D-I/TL a strong fit for digital audio interfaces with external codecs. The 32 KB SRAM supports audio sample buffering for low-latency playback at 48 kHz, and the DMA channels enable streaming without CPU intervention. The 44-pin VTLA 6x6 mm package is small enough for portable audio accessories, and the 10-bit ADC can be repurposed for auxiliary analog monitoring of supply or microphone bias.
Recommended
Low-Cost Graphics HMI with PMP
The Parallel Master Port (PMP) peripheral allows the PIC32MX150F128D-I/TL to drive small TFT LCD displays directly without an external graphics controller. Combined with 128 KB flash for storing graphics libraries and 32 KB SRAM for frame buffers in QVGA or smaller, this enables cost-effective graphical HMIs in appliances, instruments and industrial control panels. The PPS feature routes PMP signals to alternate pins, easing PCB layout against the 44-pin VTLA footprint.
Recommended
Capacitive Touch Keypads with CTMU
The integrated Charge Time Measurement Unit (CTMU) supports mTouch capacitive-touch buttons and sliders with 1 ns timing resolution, making the PIC32MX150F128D-I/TL ideal for sealed-key human-machine interfaces in appliances, security panels and consumer products. PPS simplifies routing of touch sensor traces and the 10-bit ADC reads CTMU timing voltage. The low active current under 0.5 mA/MHz preserves battery life in wireless remote controls.
Recommended
Industrial Control Nodes
The industrial -40 C to +105 C operating range and 2.3V to 3.6V supply make the PIC32MX150F128D-I/TL suitable for industrial controllers, sensor aggregators and protocol converters. UART, I2C and SPI handle fieldbus bridging, while the 10-bit ADC monitors analog process variables. The 128 KB flash holds application firmware plus protocol stacks (Modbus, custom), and the 32 KB SRAM provides headroom for RTOS use if needed.
Recommended
Consumer Devices with USB Connectivity
Consumer products requiring USB connectivity - such as wireless headphones, gaming peripherals, programmable toys and fitness wearables - benefit from the PIC32MX150F128D-I/TL's small 6x6 mm VTLA footprint, low active current, USB 2.0 FS and ample flash for user-interface firmware. The 32 KB SRAM is enough for USB endpoint buffers plus BLE/IRDA/LINbus protocol handling where simple wired control is needed. The PPS feature simplifies routing on dense consumer PCBs.

Key Differentiators
- Integrated USB 2.0 full-speed OTG with on-chip transceiver (vs PIC32MX150F128CT-V/TL)
- Industrial temperature range -40 C to +105 C as standard (vs PIC32MX150F128CT-V/TL)
- Compact 6x6 mm VTLA package with center pad cooling (vs PIC32MX150F128D-I/PT (TQFP 10x10))
Design Notes
The PIC32MX150F128D-I/TL operates from 2.3V to 3.6V and draws <0.5 mA/MHz active. For USB applications, the VBUS pin must sense 5V presence and use a 3.3V LDO (e.g., MCP1700) to regulate the rail. Place decoupling capacitors (100 nF ceramic + 4.7 uF bulk) within 2 mm of each VDD pin to suppress switching noise from the USB transceiver. Add a 1 uF tantalum or ceramic on VBUS to handle USB hot-plug transients.
The 44-pin VTLA package uses a leadless land-grid array with a center thermal pad that must be soldered to the PCB ground plane for mechanical stability and thermal dissipation. Keep digital signal traces short and away from the analog AVSS/AVDD pair to reduce ADC noise coupling. Reserve space for the 12 MHz external crystal plus load capacitors near pins OSC1/OSC2 for USB-accurate clocking.
Do not confuse the PIC32MX150F128D (with USB/PMP) with the PIC32MX150F128C (without USB). The C variant lacks the USB pins and PMP module - choosing it for a USB design is a common sourcing mistake. Also note that the I/TL suffix specifies industrial temp and VTLA package; V/TL is the extended-temp version. Use PPS configuration registers to remap peripherals rather than rotating the chip orientation in the schematic.
