PIC32MX360F256L-80V/PT Overview
What is a 32-bit microcontroller? A microcontroller (MCU) is a single-chip computer integrating a CPU core, program memory (Flash), data memory (SRAM), and on-chip peripherals such as timers, communication controllers, and analog blocks. A 32-bit MCU like the PIC32MX runs on a 32-bit datapath, allowing it to address large contiguous memory and execute instructions on wider data than 8-bit or 16-bit MCUs. PIC32MX parts use the MIPS32 M4K core, placing them in the hierarchy: microcontroller -> 32-bit MCU -> MIPS-based MCU -> PIC32 family -> PIC32MX3XX/4XX general purpose series.
Key features include 256 KB (256K x 8) Flash, 32 KB SRAM, USB 2.0 full-speed On-The-Go, an 8-channel 10-bit 1 MSPS ADC, two I2C, two SPI, two UART, five 16-bit timers/counters, a Parallel Master Port, and a JTAG/ICSP programming/debug interface. Up to 85 digital I/O pins support 5V tolerant inputs with standard PIC interrupt-on-change semantics.
Architecturally, the PIC32MX360F256L uses a 5-stage MIPS32 pipeline with hardware multiply/divide and a configurable prefetch cache. The USB module includes an internal transceiver and dedicated DMA channels, which offload packet handling from the CPU and free MIPS for application code. The peripheral bus is independent from the instruction bus, allowing concurrent Flash fetch and DMA transfers.
Typical applications include USB peripherals (HID, CDC, MSD), industrial control panels, embedded graphical user interfaces, data loggers, and sensor hubs. The combination of USB-OTG, large RAM, and DMA also suits audio processing, motor control, and any system requiring a wired USB link without an external PHY.
When designing with this part, allocate careful PCB planning for the 100-pin TQFP power and ground pins; route the 48 MHz external crystal traces short and symmetric, and provide a 1 uF + 100 nF decoupling pair per VDD/VSS pair. The PIC32MX3XX/4XX family datasheet (DS61143H) is the primary reference.

Typical Applications
PIC32MX360F256L-80V/PT is suitable for 7 applications: USB HID Peripheral, Industrial Control Panel, Embedded Data Logger, Graphical User Interface Controller, Sensor Hub with USB CDC, Audio Processing / USB Audio, Motor Control and PWM Drive.
USB HID Peripheral
The PIC32MX360F256L-80V/PT is ideal for USB Human Interface Device designs such as keyboards, mice, joysticks, and custom HID controllers. The integrated USB 2.0 full-speed controller with internal transceiver eliminates external PHY cost, and the 8-channel DMA offloads endpoint handling from the 80 MHz MIPS32 core. With 32 KB SRAM and 256 KB Flash it comfortably fits the Microchip USB stack, HID report descriptors, and application logic. The PT suffix indicates a 100-pin TQFP that exposes all 85 I/O lines for buttons, encoders, and LED matrices. Engineers should add ESD protection on DP/DM and route the 48 MHz crystal traces within 5 mm of the OSC1/OSC2 pins for USB compliance.
Recommended
Industrial Control Panel
The PIC32MX360F256L-80V/PT suits industrial control panels with its -40C to +105C V-grade operation, 85 I/O pins for key matrix scanning, and 5x 16-bit timers for PWM and quadrature decoding. The 10-bit 1 MSPS ADC handles analog sensor inputs from temperature, pressure, and current transducers, while two UARTs connect to RS-232/RS-485 transceivers for Modbus RTU. The 256 KB Flash stores the panel application plus a Modbus stack with margin, and 32 KB SRAM supports protocol buffers and display framebuffers for graphical LCDs via the Parallel Master Port. Designers should add watchdog timer firmware and TVS protection on field wiring.
Recommended
Embedded Data Logger
The PIC32MX360F256L-80V/PT works as an embedded data logger for environmental, energy, and asset tracking. The 32 KB SRAM accommodates circular sample buffers for the 10-bit ADC sampling at 1 MSPS, while 256 KB Flash stores boot code, configuration, and compression routines. The two I2C buses interface to sensors (temperature, humidity, accelerometers) and external EEPROM, and the two SPIs handle SD card mass storage or external flash. USB device mode enables fast offload to a host PC. Engineers should use the 8-channel DMA to automate SD card writes without CPU intervention, and add a coin-cell backup for RTC retention.
Recommended
Graphical User Interface Controller
The PIC32MX360F256L-80V/PT drives small graphical LCD or OLED displays via the Parallel Master Port (PMP), which provides 8/16-bit parallel interface, address latch enable, and read/write strobes typical of ST7565, SSD1963, and ILI9341 controllers. The 32 KB SRAM holds a partial framebuffer sufficient for 320x240 monochrome or 128x128 16-bit color, and the 80 MHz MIPS32 core drives SPI displays up to 40 MHz SCK. The five 16-bit timers generate display refresh PWM and touch-panel sampling clocks. Adding resistive touch support uses the on-chip 10-bit ADC on two analog inputs.
Recommended
Sensor Hub with USB CDC
The PIC32MX360F256L-80V/PT acts as a USB Communications Device Class (CDC) sensor hub, presenting multiple analog and digital sensors as virtual COM ports to a host PC. USB-OTG enables host mode for connecting USB peripherals such as barcode scanners or RFID readers. The 8-channel DMA streams sensor data into USB endpoints without CPU copy overhead, while the 80 MHz core runs sensor fusion algorithms. Use the two UARTs as debug consoles, two SPIs for high-speed sensors, and two I2C for low-speed peripherals. Power consumption is approximately 50 mA active at 80 MHz, manageable from USB bus power.
Recommended
Audio Processing / USB Audio
The PIC32MX360F256L-80V/PT handles USB audio class (UAC) streaming with the on-chip USB full-speed controller delivering up to 12 Mbps. The 256 KB Flash stores the UAC stack plus custom DSP routines, and 32 KB SRAM holds double-buffered audio samples at 48 kHz mono or 16 kHz stereo. The I2S interface on selected pins connects to external audio DACs and ADCs, while two DMA channels manage full-duplex sample transfer. The 80 MHz MIPS32 core executes real-time filters, mixing, and volume control with comfortable headroom. A low-jitter 48 MHz crystal is required for USB and audio synchronization.
Recommended
Motor Control and PWM Drive
The PIC32MX360F256L-80V/PT generates PWM signals for DC, stepper, and brushless DC motor control using its five 16-bit timers with output compare and PWM modes. The 80 MHz core and Input Capture modules measure encoder feedback with sub-microsecond resolution for closed-loop PID control. The 10-bit ADC samples motor current via shunt resistors and back-EMF sensing at 1 MSPS. USB device mode exposes a control interface for tuning parameters from a host PC. Use the Parallel Master Port to drive intelligent power module (IPM) fault signals and gate driver enables. Industrial V-grade temperature rating supports motor compartments.

Key Differentiators
- Integrated USB 2.0 full-speed with internal transceiver (vs PIC32MX340F256H-80V/PT)
- Larger Flash than PIC32MX320 sibling (vs PIC32MX320F128L-80V/PT)
- 80 MHz vs 50 MHz on newer MX1/2/5 families (vs PIC32MX350F256L-V/PT)
- Smaller Flash than PIC32MX270 alternative (vs PIC32MX270F512L-V/PT)
Design Notes
The PIC32MX360F256L-80V/PT requires 2.3V to 3.6V on VDD with separate AVdd/AVss for the ADC. Place a 100 nF decoupling capacitor within 3 mm of every VDD/AVdd pin pair, and a single bulk 10 uF ceramic near the supply pins. The 80 MHz operation draws approximately 50 mA active; use a regulator with at least 100 mA headroom and 100 mV p-p noise. Connect all VSS/AVss pins to a solid ground plane with multiple vias for thermal dissipation.
Place the 48 MHz crystal (or 8 MHz crystal with PLL configuration) within 5 mm of the OSC1/OSC2 pins. Route crystal traces on the top layer over a continuous ground pour with no signal crossings, and surround them with a ground guard ring. The USB DP/DM traces must be 90 ohm differential, length-matched within 1 mm, and routed directly to the connector without stubs. Keep DP/DM away from clock signals and switching power nodes to maintain USB compliance.
Do not omit the 10 kohm pull-up on the MCLR pin, or the device will fail to start reliably and ICSP programming will be impossible. Configure unused I/O pins as outputs driving low to minimize supply current and reduce EMI susceptibility. When migrating from PIC32MX3XX to PIC32MX5XX/6XX/7XX families, double-check pin multiplexing because USB and PMP pin assignments differ between family members despite the same 100-pin TQFP.
The 80 MHz internal clock generates harmonics up to 400 MHz; treat all clock and high-speed signal traces as transmission lines. The Parallel Master Port outputs at 80 MHz and benefit from series 22 ohm damping resistors near the MCU. Use the ICSP programming clock (PGECx/PGEDx) pins exclusively for in-circuit programming; do not assign them to peripherals unless alternate pin remapping is verified in your specific device variant.
