A microcontroller (MCU) is a single-chip computer integrating a CPU core, program memory (Flash), data memory (SRAM), and peripheral set into one IC. The PIC32MX family belongs to the wider taxonomy: microcontroller -> embedded processor -> semiconductor IC. Within Microchip's portfolio it sits in the PIC32MX3xx/4xx performance tier, offering higher peripheral integration than PIC32MX1xx/2xx parts while remaining lower cost than PIC32MZ devices.
Key features include two SPI/I2S ports, two I2C, two UART, a 10-bit ADC with up to 28 analog channels, two analog comparators, five 16-bit timers, and a Parallel Master Port for external memory bus. Hardware multiplier/Divider, trace support, and a 5-bit RTCC round out the integrated peripheral set, allowing display, audio, USB-device, and capacitive-touch HMI designs without external coprocessors.
Architecturally, the M4K core implements a 5-stage pipeline with Harvard bus architecture, single-cycle 32x16 multiply, and zero-look-ahead DSP-friendly instruction set. The wide 32-bit datapath executes most instructions in one cycle, achieving 1.26 Dhrystone MIPS per MHz; at 80 MHz this yields approximately 101 DMIPS, while the related -120 variant reaches 150 DMIPS.
Typical applications include industrial control panels, HMI touch screens, low-cost USB audio peripherals, sensor aggregation nodes, and small-format graphical displays. The 100-pin TQFP footprint also makes it compatible with hobbyist and rapid-prototyping environments that favor easily-handled packages.
When selecting this device, verify the -V temperature grade matches your environment; the companion -I/port parts cover -40 to +85C industrial, while the -E grade covers -40 to +125C extended. Decoupling, trace length, and oscillator layout follow Microchip AN-Harmonics-1 and PIC32MX family reference design guidance.

Tipikal na mga Gamit
PIC32MX350F128L-V/PT ay nararapat para sa 6 aplikasyons: Industrial HMI Touch Panels, USB Audio Peripherals (Headset/Microphone), Sensor Aggregation Nodes (IoT Edge), Small-format Graphical Displays (TFT/QVGA), Automotive Under-hood (-V Temperature), Low-cost Motor Control (BLDC / Stepper).
Industrial HMI Touch Panels
The PIC32MX350F128L-V/PT suits industrial HMI panels with capacitive touch because it integrates a parallel master port (PMP) for direct connection to TFT/QVGA displays and a 10-bit ADC for ambient light sensing. At 80 MHz the M4K core executes Microchip's Graphics Object Layer and mTouch libraries smoothly, while the 32 KB SRAM holds a 320x240x16b frame buffer. The -V grade ( -40C to +105C ) withstands factory-floor cabinet temperatures, and the 100-pin TQFP leaves plenty of GPIO for backlight PWM, buzzer, and CAN-bus isolation. Pin-compatible PIC32MX270F256L-V/PT upgrades flash to 256 KB when project size grows.

USB Audio Peripherals (Headset/Microphone)
The PIC32MX350F128L-V/PT integrates a USB 2.0 Full-Speed device controller plus two I2S ports, enabling USB headset, USB microphone, and USB audio-class designs without an external CODEC in many cases. With 80 MHz CPU and 32 KB SRAM, isochronous USB audio at 48 kHz/16-bit stereo fits the bandwidth budget with headroom for the Microchip USB audio driver stack. The 100-pin TQFP exposes the secondary I2S for daisy-chained DSP/effects, and the 28-channel 10-bit ADC handles push-button and jack-detection inputs. Drop-in compatibility with PIC32MX350F256L-V/PT allows firmware reuse when larger USB descriptors are required.

Sensor Aggregation Nodes (IoT Edge)
The PIC32MX350F128L-V/PT's combination of 28-channel 10-bit ADC, two I2C, two SPI/I2S, two UART, and 80 MHz core makes it well-suited as an edge-of-network sensor aggregator that pre-processes analog and digital sensor data before forwarding over UART/SPI to a host MCU or radio module. The 32 KB SRAM buffers short time-series samples without external memory. The -V temp grade supports outdoor enclosure designs; the 100-pin TQFP retains headroom for expansion (additional UARTs via software bit-banging). Pin-compatible PIC32MX170F512L-V/PT upgrades flash to 512 KB for richer on-device analytics.

Small-format Graphical Displays (TFT/QVGA)
Driving a 320x240 TFT display requires a parallel master port plus sufficient RAM for a frame buffer; the PIC32MX350F128L-V/PT provides PMP on PORTD/PORTF/PORTG and 32 KB SRAM, sufficient for a QVGA 16-bpp buffer. The 80 MHz core renders widgets, anti-aliased text, and 2D primitives from Microchip's Graphics Library at acceptable frame rates. The 100-pin TQFP keeps signal-trace fanout easy to route. Drop-in compatibility with PIC32MX570F512L-V/PT enables higher-performance rendering if scene complexity grows.

Automotive Under-hood (-V Temperature)
The PIC32MX350F128L-V/PT -V temp rating (-40C to +105C) targets automotive under-hood environments such as engine-bay sensor modules, HVAC actuators, and lighting controllers. The 80 MHz core handles CAN-based J1939 stacks, while the integrated ADC and comparators interface directly with thermistors, pressure sensors, and current shunts. The 100-pin TQFP is acceptable for hand-repairable automotive ECUs; high-volume modules typically migrate to QFN. Pin-compatible parts ensure long-term supply.

Low-cost Motor Control (BLDC / Stepper)
The PIC32MX350F128L-V/PT's five 16-bit timers, two analog comparators, and 80 MHz core support sensorless BLDC, brushed DC, and stepper motor control loops when paired with external gate drivers. The 10-bit ADC samples back-EMF and current at sufficient rates for low-RPM applications. The 100-pin TQFP provides GPIO for Hall-sensor inputs, fault flags, and PWM outputs. Pin-compatible PIC32MX270F256L-V/PT upgrades flash for complex FOC-less commutation algorithms.

Talaan ng Disenyo
The PIC32MX350F128L-V/PT requires a regulated 2.3-3.6 V rail; use a low-noise LDO such as Microchip MCP1700 or equivalent rated for at least 100 mA peak. Place a 10 uF + 0.1 uF decoupling network within 5 mm of each VDD/VSS pin pair, plus 4.7 uF + 0.1 uF on AVDD/AVSS. The VUSB pin (when USB is used) needs its own filtered 3.3 V from the internal voltage regulator; reference Microchip AN-Harmonics-1 for proper USB power sequencing.
Keep the primary 8/16 MHz crystal traces short (< 5 mm) and symmetric; place the crystal within 5 mm of OSC1/OSC2. Route USB DP/DM as a 90-ohm impedance differential pair with no stubs. The parallel master port (PMP) signals on PORTD/PORTF/PORTG should be length-matched to within 50 mil for QVGA displays to avoid skew.
Do not confuse -V (extended -40 to +105C), -I (industrial -40 to +85C), and -E (extended -40 to +125C) temperature grades - they share the same die but different screening. Do not apply >3.6 V to any I/O; the M4K core does not tolerate 5 V. Enable the JTAGEN fuse only when needed, as it consumes ~5 mA. Programming pins PGECx/PGEDx must be accessible for ICSP regardless of final pin assignment.
