PIC32MX350F128LT-I/PF Обзор
A microcontroller (MCU) is an integrated circuit that contains a processor core, program memory, data memory, and configurable peripherals on a single die. Microcontrollers form the control backbone of embedded systems, ranging from consumer appliances to industrial automation. Within the broader taxonomy, the PIC32MX350 sits in the 32-bit MCU category, above 8-bit and 16-bit microcontrollers in raw performance (measured in DMIPS), and below microprocessor units (MPUs) that require external memory.
Key features include 100 MHz/131 DMIPS core performance, Peripheral Pin Select (PPS) for flexible pin assignment, an on-chip Charge Time Measurement Unit (CTMU), an RTCC with calendar mode, and hardware crypto acceleration on select variants. The I2S/SSP interfaces enable direct connection to audio codecs for multimedia applications. The 2.3V to 3.6V operating range makes the device suitable for battery-powered designs.
The PIC32 architecture implements a five-stage pipeline with Harvard-style separate Flash and SRAM buses, supporting single-cycle Flash access with prefetch. This results in deterministic interrupt latency suitable for hard-real-time control loops. The integrated DMA engine offloads data movement from the core, enabling peripherals such as the PMP (for graphics interfaces) and ADC to operate without CPU intervention.
Typical applications include industrial motor control, USB peripherals, graphical user interfaces (PMP-driven LCDs), audio playback devices, IoT edge nodes, and automotive body modules. The wide peripheral mix makes the PIC32MX350 particularly attractive when a single chip must serve as USB host/device, run a graphical HMI, and communicate with sensors via I2C/SPI/UART.
Designers should plan oscillator and decoupling layout to meet the 80 MHz timing budget; PPS remapping must be configured early in initialization since PPS lock bits are one-way programmable. Power sequencing considerations apply when interfacing with 5V logic - use level shifters since I/O are not 5V tolerant on most pins.

Типичное применение
PIC32MX350F128LT-I/PF подходит для 6 применениеs: Industrial Motor Control and Drive, USB Peripherals and HID Devices, Graphical HMI with PMP-Driven LCDs, Audio Playback Devices with I2S Codecs, IoT Edge Nodes and Sensor Hubs, Automotive Body and Comfort Modules.
Industrial Motor Control and Drive
The PIC32MX350F128LT-I/PF is well suited for industrial motor control applications where its 80 MHz MIPS32 M4K core delivers deterministic 100 MHz-class DMIPS performance for FOC and PID loops. The integrated 10-bit ADC with up to 28 channels samples phase currents and bus voltage with hardware-triggered conversion synchronized to PWM, while 6 UART channels link to sensor and gateway subsystems. Hardware CTMU enables capacitive touch sensing for HMI panels on industrial machinery. The 2.3-3.6V operating range and -40 to +105 C industrial temperature rating ensure reliable operation on factory floors.
Рекомендуется
USB Peripherals and HID Devices
The PIC32MX350F128LT-I/PF integrates a USB 2.0 Full-Speed controller with on-chip transceiver and OTG support, eliminating the need for an external PHY. With 80 MHz CPU performance and 32 KB RAM, the part runs the Microchip USB stack (HID, CDC, MSD, audio) alongside application firmware. USB endpoints and DMA offload data movement from the core, sustaining 12 Mbps throughput while leaving CPU bandwidth for protocol handling. OTG mode enables dual-role device/host designs such as USB keyboards, custom test instruments, and field-updatable industrial terminals.
Рекомендуется
Graphical HMI with PMP-Driven LCDs
The PIC32MX350F128LT-I/PF includes a Parallel Master Port (PMP) capable of driving 8-bit or 16-bit parallel LCDs, making it a strong choice for graphical HMI panels in appliances, point-of-sale terminals, and instrument front panels. The 80 MHz core and DMA controller refresh the display without CPU overhead, while the Peripheral Pin Select (PPS) reassigns digital functions to alternate pins to avoid PMP pin conflicts. With 128 KB Flash, the device accommodates full-framebuffer or compressed graphics libraries (TinyGL, Microchip gfx) for typical 320x240 or 480x272 panels.
Рекомендуется
Audio Playback Devices with I2S Codecs
The PIC32MX350F128LT-I/PF features two SPI/I2S modules that interface directly with audio codecs (e.g., Wolfson/Cirrus devices) for digital audio playback and recording. At 80 MHz, the MCU executes audio processing algorithms (graphic EQ, dynamic range compression, mixing) with low CPU overhead. The DMA engine streams samples between codec and memory without CPU intervention, freeing bandwidth for UI logic. With 32 KB RAM the device handles typical 48 kHz / 16-bit stereo playback buffers comfortably, making it suitable for Bluetooth speakers, intercoms, and standalone audio alert modules.
Рекомендуется
IoT Edge Nodes and Sensor Hubs
The PIC32MX350F128LT-I/PF operates across 2.3-3.6V with low-power sleep modes, making it suitable for battery-powered IoT edge devices and sensor hubs. Six UART and two I2C channels aggregate multiple sensor inputs (temperature, humidity, motion) to a wireless co-processor via UART or SPI. The CTMU and 28-channel ADC interface directly with capacitive touch buttons and analog sensors without external components. Peripheral Pin Select allows pin re-routing to optimize PCB layout for compact wearable and smart-home device form factors.
Рекомендуется
Automotive Body and Comfort Modules
The PIC32MX350F128LT-I/PF (industrial grade variant) suits non-safety automotive body electronics such as HVAC controls, seat controllers, and lighting modules that require rich peripheral integration but not AEC-Q100 qualification. CAN peripheral networking, 6 UART channels, and the CTMU drive capacitive touch interfaces for steering-wheel switches and door panels. With 128 KB Flash and 32 KB RAM, the device hosts comfort control algorithms, lighting fade sequences, and LIN/CAN gateway logic simultaneously. For AEC-Q100 designs, Microchip offers automotive-grade PIC32MX variants in the same family.

Заметки по проектированию
Place 0.1uF ceramic decoupling capacitors as close as possible to each VDD pin (12 pins total on TQFP-100). Add a single 10uF bulk capacitor near the package. Separate analog supply (AVDD/AVSS) and digital supply pins - both are required even if the MCU does not use ADC. Use ferrite bead isolation if AVDD is sourced from a noisy digital rail to preserve ADC accuracy.
TQFP-100 has 0.5mm pitch pins requiring careful PCB layout. Use at least 4-layer board with dedicated ground plane to control trace impedance and minimize EMI. Route the 8 MHz or 10 MHz primary crystal traces symmetrically within 1 cm of OSC1/OSC2 and shield with a ground guard ring. MCLR pin requires external 10k pull-up to VDD; do not leave floating.
Peripheral Pin Select (PPS) lock bits are one-way programmable - if your firmware accidentally locks an unintended mapping, the device must be reset and the configuration erased via ICSP. Always validate PPS assignments during development before deploying. Additionally, the I2C module uses open-drain outputs requiring external pull-up resistors (typically 4.7k) on SCL/SDA lines.
USB D+/D- lines require 90-ohm differential routing and matched length to within 150 mil for USB Full-Speed compliance. Place the 15k pull-down resistor on D- at the device side. Keep USB traces away from high-frequency switching nodes. The integrated USB PHY requires precise 48 MHz clock; use a crystal with low ppm tolerance (50 ppm max) to avoid USB certification failures.
