PIC32MX350F128LT-V/TL - 32-bit 80MHz MCU 128KB Flash | Microchip
MPN: PIC32MX350F128LT-V/TL ✓ Hoạt độngPIC32MX350F128LT-V/TL Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory, and programmable peripherals on one die. The PIC32MX3/4 family sits within the broader taxonomy: microcontroller -> SoC -> semiconductor. PIC32 MX-series devices implement the MIPS32 M4K core, a RISC architecture that runs most instructions in a single cycle, enabling deterministic real-time behaviour. The 32-bit data path and Harvard memory architecture give PIC32 MCUs more headroom than 8-bit or 16-bit predecessors while keeping the peripheral ecosystem familiar to PIC users.
Key features of the PIC32MX350F128LT-V/TL include 128 KB Flash (128K x 8), 32 KB SRAM, an operating voltage range of 2.3 V to 3.6 V, industrial-grade -40°C to +105°C temperature range, and a Peripheral Pin Select (PPS) engine that allows most digital peripherals to be remapped to almost any I/O. The device also includes a Parallel Master Port (PMP), USB 2.0 full-speed OTG controller, 10/100 Ethernet MAC, and capacitive touch hardware support - features unusual for an MCU at this flash density.
Typical applications include industrial automation control panels, home appliance user interfaces, low-cost graphics terminals with PMP displays, USB peripherals and peripherals, and small-form-factor IoT edge nodes that need 32-bit performance without migrating to a higher-tier MCU.
A practical design tip: leverage Peripheral Pin Select (PPS) to route peripherals after pinout is locked, but remember that PPS remapping is per-function, not per-pin, so designers must still assign physical pads carefully to keep analog and digital paths separate on the 124-pin VTLA package.

PIC32MX350F128LT-V/TL phù hợp cho 7 Áp dụngs: Industrial Control Panels, USB Peripherals, Home Appliance UI, Low-Cost Ethernet Nodes, Graphics Terminals with PMP, IoT Edge Sensor Hubs, Automotive Body Controllers.
Industrial Control Panels
The PIC32MX350F128LT-V/TL fits industrial HMI panels because its 80 MHz MIPS32 M4K core runs graphical menus faster than 8-bit predecessors, and 128 KB Flash holds full keypad/display state machines. The 124-pin VTLA exposes enough GPIO for matrix keypads, character LCDs, and LED bar graphs. Industrial-grade -40C to +105C operation tolerates cabinet heat. Built-in UART, SPI, and I2C simplify links to motor drives and sensors.

USB Peripherals
The PIC32MX350F128LT-V/TL's integrated USB 2.0 full-speed OTG controller makes it a natural fit for USB peripherals like HID controllers, USB-to-UART bridges, and low-cost data loggers. The 128 KB Flash holds USB stacks and application code; 32 KB SRAM accommodates HID ring buffers. The 124-pin VTLA footprint exposes dedicated USB D+/D- pads. No external PHY needed, reducing BOM and PCB area versus discrete USB chips.

Home Appliance UI
The PIC32MX350F128LT-V/TL suits home appliance user interfaces - washing machine panels, induction cooktops, and smart thermostats - where its 28-channel ADC reads multiple knob positions and NTC temperature sensors in parallel. The 128 KB Flash holds multilingual UI strings and capacitive touch libraries. The -40C to +105C range covers kitchen and laundry enclosures. PMP peripheral drives character LCDs without an external display controller.

Low-Cost Ethernet Nodes
The PIC32MX350F128LT-V/TL integrates a 10/100 Ethernet MAC that, paired with a low-cost PHY like the LAN8720, gives designers a sub-$10 networked MCU for sensors, smart plugs, and small appliances. The 32 KB SRAM buffers lightweight TCP/IP stacks. The 124-pin VTLA exposes RMII pads via PPS. Internal MII/RMII/mux eliminates external logic, simplifying PCB layout versus MCUs without an integrated MAC.

IoT Edge Sensor Hubs
The PIC32MX350F128LT-V/TL aggregates multiple sensors via I2C, SPI, and UART for IoT edge hubs - small-form-factor devices bridging peripherals to local processing. The 28-channel ADC scans analog sensors while digital buses connect environmental, motion, and gas sensors. Built-in USB and Ethernet provide either local console or networked telemetry. -40 °C to +105 °C supports outdoor enclosures and factory floors.

Ghi chú thiết kế
The PIC32MX350F128LT-V/TL's VTLA-9x9 package dissipates up to ~500 mW at 80 MHz with full peripheral activity. Estimated: at 3.3 V core, internal current is roughly 60 mA (3.3 V x 60 mA = 200 mW), plus I/O loading. The exposed thermal pad MUST be soldered to a continuous ground copper pour of at least 1 sq cm; failure to do so can raise junction temperature by 15-20 C above datasheet curves. For high-temperature industrial environments, use a 4-layer PCB with a dedicated ground plane for thermal relief.
Route the 50 MHz Ethernet RMII traces as a matched-length group with 50 ohm impedance to the external PHY. Keep USB D+/D- as a 90-ohm differential pair. Place the 12 MHz primary crystal within 5 mm of the OSC1/OSC2 pads, with a guarded ground ring around the crystal traces. Decouple VDD with 100 nF ceramic caps adjacent to every VDD pin and a single bulk 4.7 uF tantalum within 10 mm.
Avoid the common mistake of leaving unused I/O as inputs - floating inputs on PIC32MX can draw several mA in aggregate and cause spurious interrupts. Configure unused I/O as outputs driving low. Do not exceed 3.6 V on any I/O; the PIC32MX350 is NOT 5V tolerant. When using PPS, remap functions in the device header rather than directly writing registers - register macros handle unlock sequences that prevent lockout.
Use a low-noise LDO such as MCP1700B or MIC29150 for the 3.3 V rail - the PIC32MX350's ADC accuracy degrades if the supply ripple exceeds 30 mV pk-pk. Keep the LDO within 50 mm of the VDD pins and use a star-ground layout to isolate analog and digital returns. Add a 10 uF bulk cap on VDDIO and AVDD separately to reduce ADC reference noise.
