PIC32MX150F256L-50I/PF 개요
What is a 32-bit microcontroller? A microcontroller (MCU) is a single-chip computer containing a CPU core, Flash program memory, SRAM data memory, and a rich set of peripherals such as timers, ADC, communication interfaces, and I/O. The "32-bit" designation refers to the width of the data path and registers, enabling higher throughput, larger address space, and richer data processing than 8-bit or 16-bit MCUs. The PIC32MX1XX/2XX/5XX family sits within Microchip's broader PIC32 portfolio, optimized for cost-sensitive 32-bit applications including human-machine interfaces (HMI), audio playback, and connectivity.
Key features include 50 MHz / 83 DMIPS core performance, USB 2.0 Full-Speed device/host/OTG, 10-bit 1 Msps ADC with up to 28 channels, up to four UART modules, two I2C modules, an 8-bit Parallel Master Port, and an on-chip 80 MHz RTCC. The integrated CTMU (Charge Time Measurement Unit) supports capacitive touch sensing, eliminating the need for an external touch controller.
Architecturally, the PIC32MX150F256L-50I/PF leverages the MIPS M4K core with a 5-stage pipeline, single-cycle multiply, and hardware multiply/divide. The wide memory bus and dual read/write PMP buffers accelerate graphics and external memory transactions, while PPS allows designers to remap digital peripherals onto most I/O pins, simplifying PCB routing on dense 100-pin layouts.
Typical applications include industrial control panels, USB audio peripherals, low-cost HMI with TFT displays, consumer electronics, capacitive touch keypads, motor control, and embedded data logging with USB mass storage. The 2.3 V to 3.6 V Vcc range and -40 C to +85 C industrial temperature grade support rugged environments.
When designing with this MCU, allocate decoupling capacitance close to every Vdd/Vss pair and use the PMP in master mode with the dual buffers to sustain LCD refresh rates. PPS mapping must be locked via config bits to prevent accidental re-mapping at runtime.

일반적인 애플리케이션
PIC32MX150F256L-50I/PF 적합 용도: 6 애플리케이션s: Industrial HMI Control Panel, USB Audio Peripherals, Capacitive Touch Keypad, USB Mass Storage Data Logger, Motor Control and BLDC Drive, Consumer Wearable Device.
Industrial HMI Control Panel
The PIC32MX150F256L-50I/PF fits industrial HMI panels because of its integrated Parallel Master Port (PMP) with dual read/write buffers that sustain TFT LCD refresh at 60 Hz without external bus controllers. With 50 MHz/83 DMIPS core, 32 KB SRAM buffers entire menu structures and Modbus RTU stacks, while the 100-pin TQFP exposes up to 78 I/O for key matrices, status LEDs, and rotary encoders. The 2.3 V to 3.6 V Vdd range and -40 C to +85 C industrial temperature grade ensure reliable operation in factory environments, and PPS remapping allows routing USB, UART, and SPI to convenient board locations.

USB Audio Peripherals
For USB audio peripherals such as USB speakers and headsets, the PIC32MX150F256L-50I/PF's on-chip USB 2.0 Full-Speed OTG controller handles 12 Mbps isochronous audio streams without external transceivers, and the two I2S interfaces support DAC/ADC pairs at standard 44.1/48 kHz. The 256 KB Flash accommodates USB audio class drivers and small DSP pre-effects, while 32 KB SRAM is sufficient for USB endpoint buffers plus audio frame queues. The CTMU enables capacitive mute/volume buttons, and the 50 MHz MIPS M4K core sustains 8 kHz to 48 kHz sample-rate conversion on-chip.
추천
Capacitive Touch Keypad
The PIC32MX150F256L-50I/PF implements capacitive touch sensing via its on-chip CTMU (Charge Time Measurement Unit), removing the need for an external touch controller and reducing BOM cost on consumer appliances. With 50 MHz MIPS M4K, the core scans 10-20 touch electrodes at 100 Hz refresh while running a user interface; 32 KB SRAM buffers gesture state, while 256 KB Flash stores configurable touch profiles. The mTouch library from Microchip provides ready algorithms, and PPS remaps touch channels onto unused I/O pins, simplifying PCB layout under the keypad.
추천
USB Mass Storage Data Logger
The PIC32MX150F256L-50I/PF serves as a USB mass storage data logger for industrial and environmental monitoring. Its USB 2.0 Full-Speed On-The-Go controller enumerates as a removable drive when plugged into a host PC, allowing direct file access to a microSD card connected via PMP. With 50 MHz and 32 KB SRAM, the MCU manages FAT32 writes at 200 KB/s while sustaining an ADC sample stream at 1 Msps into the 256 KB Flash-backed buffer. PPS remapping keeps the PMP and USB pins on convenient board locations.
추천
Motor Control and BLDC Drive
The PIC32MX150F256L-50I/PF drives BLDC and stepper motors using its 50 MHz core for field-oriented control (FOC) loops at 20 kHz PWM while leaving CPU headroom for UART telemetry and USB diagnostics. The PWM-triggered 10-bit ADC at 1 Msps synchronizes current sampling with the PWM edge, the CTMU measures back-EMF, and PPS remaps PWM channels onto any GPIO for board flexibility. Industrial temperature grade and 2.3-3.6 V Vdd tolerate noisy motor bus environments.
추천
Consumer Wearable Device
In consumer wearables such as fitness bands and BLE bridges, the PIC32MX150F256L-50I/PF acts as a sensor hub processor: 50 MHz/83 DMIPS runs pedometer and gesture algorithms, while the four SPI ports connect to BLE modules, IMUs, and heart-rate sensors. The 256 KB Flash stores BLE profiles and pedometer firmware, 32 KB SRAM is enough for sensor fusion buffers, and the 100-pin TQFP package fits wearables with rich peripheral expansion. USB 2.0 FS enables charging and firmware upgrade docks, while CTMU supports touch strip controls.

- Includes on-chip CTMU for capacitive touch without external controller (vs PIC32MX250F256L-50I/PF)

설계 노트
Place a 100 nF decoupling capacitor as close as possible to every Vdd/Vss pair of the PIC32MX150F256L-50I/PF, with an additional 10 uF bulk capacitor near the package to supply the 50 MHz core transient load. For USB applications, add a 100 nF + 4.7 uF pair on the VUSB pin to filter USB transceiver supply; without proper decoupling the USB eye diagram can degrade and cause enumeration failures.
Lock Peripheral Pin Select (PPS) mappings via configuration bits or early initialization code, because PPS registers default to a safe but non-functional mapping and runtime re-mapping can cause momentary glitches on remapped peripherals. Always reserve at least 4.7 kohm pull-ups on I2C lines and unused I/O pins, and route the 50 MHz clock trace in the shortest possible length to minimize EMI.
Estimated: at 50 MHz core clock with all peripherals enabled and USB active, the PIC32MX150F256L-50I/PF can draw up to 70 mA from Vdd; the 100-pin TQFP package has theta_JA of approximately 35-40 C/W on a 4-layer JEDEC test board, so the die temperature rises 2-3 C above ambient at full load. A small copper pour on the 100-pin TQFP exposed pad (when present) is recommended, although the TQFP package itself lacks a true EP. Watch out for in-application programming (IAP) timing when the entire Flash is written - sector-erase followed by full-chip write takes ~2 seconds.
