PIC32MX350F128LT-V/PF Descripción general
A 32-bit microcontroller (MCU) is a single-chip computer built around a 32-bit datapath, providing significantly higher arithmetic throughput, larger addressable memory, and richer peripherals than 8-bit or 16-bit MCUs. The PIC32MX350 family sits in the category hierarchy MCU -> embedded microcontroller -> 32-bit RISC processor -> MIPS32 M4K core -> Microchip PIC32 product line. This positioning makes it suitable for code-intensive applications where 8-bit PIC MCUs run out of headroom but full application processors (Linux-class SoCs) are over-spec.
Key features of the PIC32MX350F128LT-V/PF include two I2C, two SPI/I2S, two UART, two analog comparators, five 16-bit timers/counters, a 28-channel 10-bit ADC at 1 Msps, and parallel master port (PMP) for external memory or graphics. The 80 MHz core delivers 1.53 DMIPS/MHz (102 DMIPS at 80 MHz in single-cycle mode), and the 128 KB Flash is partitioned for a bootloader + application + EEPROM emulation layout. The PIC32MX3/4 family supports Microchip's MPLAB Harmony and legacy MPLAB C32 toolchains with the standard MIPS soft-tools, and is supported by the PICkit and ICD debugger/programmer ecosystem.
Typical applications include industrial control HMI panels, USB peripherals (the part supports USB device/host/OTG), motor control BLDC driver boards, sensor aggregation nodes, low-cost IoT edge devices, and automotive body modules. The wide temperature range of the -V grade makes it directly suited to under-hood and dashboard deployments.
When designing with this part, allocate decoupling capacitors per the datasheet minimum (0.1 uF plus 10 uF bulk) at every VDD/AVDD/VUSB/VBAT pin pair, and place the 8 MHz crystal or resonator within 1 cm of the OSC1/OSC2 pins to avoid oscillator start-up issues. The MPLAB Harmony framework is recommended over legacy MLA to obtain working USB stacks and TCP/IP lite libraries without manual porting.

Aplicaciones típicas
PIC32MX350F128LT-V/PF es adecuado para 6 aplicacións: Industrial HMI Control Panel, USB Peripheral Devices, BLDC Motor Control Drive, Automotive Body Control Module, Sensor Aggregation IoT Edge Node, Consumer Audio USB Dongle.
Industrial HMI Control Panel
The PIC32MX350F128LT-V/PF is well suited for industrial human-machine interface (HMI) control panels where its 80 MHz MIPS32 M4K core delivers responsive UI rendering and its 28-channel 10-bit ADC handles backlight sensing, temperature compensation, and analog inputs. The 128 KB Flash supports a graphical menu system with multiple language tables, while 32 KB SRAM accommodates RTOS task stacks and frame buffers. The parallel master port (PMP) connects directly to TFT LCD controllers, eliminating the need for an external graphics bridge IC. Compared to 8-bit PIC16 alternatives, this part cuts UI refresh latency by 60-70%.
Recomendado
USB Peripheral Devices
The PIC32MX350F128LT-V/PF integrates a USB 2.0 full-speed device/host/OTG controller, making it a one-chip solution for USB peripherals such as HID input devices, data loggers, or industrial USB-to-serial bridges. The 80 MHz core sustains full-speed 12 Mbps throughput with CPU headroom for protocol stacks, while 32 KB SRAM holds descriptor buffers and ring buffers without external memory. The -V temperature grade supports deployment in environments up to 105C such as factory automation enclosures. Pairing the part with a USB Type-C CC controller enables modern connector support without redesigning the MCU section.
Recomendado
BLDC Motor Control Drive
The PIC32MX350F128LT-V/PF drives BLDC motor control loops at switching frequencies up to 50 kHz thanks to its 5 x 16-bit timers with PWM, 80 MHz MIPS core, and 28-channel 10-bit ADC for back-EMF and current sensing. The PWM modules support center-aligned and complementary outputs with dead-time insertion, eliminating the need for an external gate-driver MCU. With 128 KB Flash and 32 KB SRAM, this part can host Microchip's MPLAB Harmony motor-control libraries with field-oriented control (FOC) at moderate RPMs. The -40C to +105C temperature range suits under-hood and industrial cabinet deployments.
Recomendado
Automotive Body Control Module
The -V suffix on PIC32MX350F128LT-V/PF designates the automotive temperature grade (-40C to +105C), making the part a fit for body-control modules that manage lighting, door locks, wiper controllers, and seat memory. The 28-channel 10-bit ADC reads multiplexed switch positions and analog sensors, while two CAN-friendly UART channels and two SPI/I2S ports interface with external actuators and audio modules. The 128 KB Flash supports OBD-II-style diagnostic protocol stacks and CAN-compatible firmware for body modules. Note: AEC-Q100 qualification is not explicitly stated for this family; verify with Microchip automotive part matrix for production deployment.
Recomendado
Sensor Aggregation IoT Edge Node
The PIC32MX350F128LT-V/PF serves as a low-power aggregation node for IoT edge applications such as building automation or industrial sensor hubs. The 28-channel 10-bit ADC scans multiple analog sensors (temperature, humidity, pressure, light) with 1 Msps aggregate throughput, while two I2C and two SPI/I2S interfaces connect to digital sensors and radio modules. The 80 MHz core aggregates and pre-processes sensor data before forwarding to a gateway over UART/SPI, offloading the cloud radio with edge computation. The 32 KB SRAM supports circular buffers for sensor frame accumulation without dropped samples.
Recomendado
Consumer Audio USB Dongle
The PIC32MX350F128LT-V/PF's two SPI/I2S modules enable streaming audio paths to external DACs, while its USB 2.0 full-speed device controller handles USB Audio Class 1.0 enumeration and isochronous transfers. The 80 MHz MIPS32 M4K core comfortably runs a software USB Audio stack plus a mixer/effects stage in 128 KB Flash and 32 KB SRAM. Compared to MCU-only solutions without I2S, this part eliminates the need for an external USB audio bridge IC, reducing BOM cost and PCB area. The -40C to +105C range supports use in enclosures that warm under continuous audio streaming.

Notas de diseño
The PIC32MX350F128LT-V/PF requires a clean 3.3V supply on VDD pins 1, 26, 51, and 76, with VSS on pins 27, 50, 77, and 100. Per the Microchip datasheet, place one 0.1 uF decoupling capacitor on every VDD/VSS pair plus a single 10 uF bulk capacitor near the IC. The VUSB pin (when used for USB) needs its own 0.1 uF decoupling capacitor per the USB peripheral section of the data sheet, and the VBUS sense input should be connected through a voltage divider if the supply is 5V tolerant.
Place the 8 MHz primary crystal or resonator within 1 cm of the OSC1 (pin 17) and OSC2 (pin 18) pads, and route traces as differential pairs with ground shielding to avoid oscillator start-up issues. For USB designs, route the USB D+ and D- lines on RG2 (pin 87) and RG3 (pin 88) as a 90 ohm differential pair on the top layer over a continuous ground plane, with total length kept under 50 mm to meet USB 2.0 full-speed signal integrity requirements.
Estimated: in MPLAB X IDE, ensure the configuration bits match the -V (automotive) temperature grade when programming the part to avoid incorrect device ID mismatches during debug. Common mistakes include leaving the JTAGEN fuse enabled (which prevents ICSP programming), choosing a PLL multiplier that pushes the core above 80 MHz, and not enabling the FVBUSDET fuse for USB VBUS sensing. Always verify the CONFIG register settings match the application note AN1043 for the PIC32MX3xx/4xx family before code commit.
Información de cumplimiento
RoHS compliant per Microchip product page. -V temperature grade (-40C to +105C) is automotive-grade but Microchip does not explicitly list AEC-Q100 qualification for the PIC32MX3xx/4xx family in the public datasheet; verify automotive part matrix before deploying in AEC-qualified systems.
