PIC32MX360F512LT-80V/PT Overview
What is a PIC32MX microcontroller? PIC32MX is Microchip's family of high-performance 32-bit Flash microcontrollers based on the MIPS32 M4K core, designed for embedded applications that exceed the performance envelope of 8/16-bit MCUs. The PIC32MX360F512L sits in the PIC32MX3XX/4XX general-purpose/USB sub-family, bridging low-cost 32-bit processing with extensive connectivity (USB 2.0 FS, CAN, Ethernet MAC) for industrial, consumer, and USB-device designs.
Key features include 512 KB Flash (512K x 8), 32 KB SRAM, an 80 MHz core speed (100 MHz / 80 MHz dual-speed grade), 16-bit wide instructions for code density, and a rich peripheral mix: 10-bit 1 Msps ADC, 5 timers/counters, 2 I2C, 2 SPI, 2 UART, PMP for graphics/parallel bus, and USB 2.0 Full-Speed OTG. The integrated DMA engine enables peripheral-to-memory transfers without CPU intervention.
Architecturally, the M4K core uses a 5-stage pipeline and Harvard bus architecture, with separate 32-bit instruction and 32-bit data paths plus a tightly-coupled prefetch module that hides Flash wait states at high MIPS rates. The PT suffix denotes the 100-pin TQFP package, while the LT suffix indicates tape-and-reel packaging and the 80V/80I temperature variants.
Typical applications include USB peripherals (HID, CDC, mass storage), industrial control panels with PMP-driven LCDs, sensor hubs with DMA-driven ADC sampling, and low-cost Ethernet gateways using the integrated MAC with an external PHY. The wide memory (512 KB) supports full USB stacks and TCP/IP applications.
When designing with this part, plan the trace layout for the analog AVdd/AVss pair to preserve ADC accuracy at 1 Msps, and use the dedicated Vbus/Vusb net on the core supply rail. The device is part of Microchip's mature PIC32MX3XX/4XX family with extensive MPLAB X IDE and Harmony framework support.

Typical Applications
PIC32MX360F512LT-80V/PT is suitable for 6 applications: USB HID / CDC Peripherals, Industrial Control Panels (PMP-driven LCD), Sensor Hubs with DMA-driven ADC Sampling, Low-cost Ethernet Gateways, Motor Control (BLDC / Stepper), Portable Medical / Wellness Devices.
USB HID / CDC Peripherals
The PIC32MX360F512LT-80V/PT integrates USB 2.0 Full-Speed OTG with on-chip transceiver and 512 KB Flash, ideal for USB Human Interface Device (HID), Communication Device Class (CDC), and mass storage applications. The 80 MHz MIPS32 M4K core executes the USB stack and application code concurrently, while DMA offloads endpoint buffer management. Microchip's MPLAB Harmony USB stack provides certified HID/CDC/MSC class drivers. The 32 KB SRAM accommodates full-speed isochronous endpoints. Compared to external USB controllers, the integrated USB saves BOM cost and PCB area. The PT package's 85 I/O pins are sufficient for USB-HID keypad matrix plus status LEDs and UART debug port typical in industrial input devices.

Industrial Control Panels (PMP-driven LCD)
The PIC32MX360F512LT-80V/PT's Parallel Master Port (PMP) directly drives character and graphical LCDs in industrial HMI panels, eliminating external LCD controller ICs. With 85 I/O pins in the PT package, the MCU can drive a 4x4 keypad matrix, multiple status LEDs, and a 320x240 QVGA TFT via PMP while running the user interface. The 80 MHz core renders fonts and handles touch input without lag. The 512 KB Flash supports full LVGL-style graphics libraries. The 32 KB SRAM provides double-buffered framebuffer for smooth animation. Industrial-grade -40C to +105C V-temperature rating handles factory floor thermal stress. Microchip's MPLAB Harmony PMP driver accelerates development.
Recommended
Sensor Hubs with DMA-driven ADC Sampling
The PIC32MX360F512LT-80V/PT's integrated 10-bit 1 Msps ADC combined with multi-channel DMA enables continuous sensor sampling without CPU load - critical for multi-sensor IoT edge nodes. DMA can ping-pong between ADC result buffers in the 32 KB SRAM while the 80 MHz core processes averaged readings. The two I2C and two SPI ports support simultaneous sensor clusters (temperature, pressure, motion). USB or UART outputs aggregated telemetry. The 512 KB Flash stores calibration tables and DSP filter coefficients. The V-temperature grade (-40C to +105C) suits outdoor and automotive sensor deployments. Microchip's MPLAB Code Configurator auto-generates DMA-driven ADC setup code.
Recommended
Low-cost Ethernet Gateways
The PIC32MX360F512LT-80V/PT features an integrated Ethernet MAC that, paired with an external PHY (such as the Microchip LAN8720A or DP83848), creates a low-cost TCP/IP gateway for industrial and building automation. The 512 KB Flash hosts the full Microchip TCP/IP stack (TCP, UDP, HTTP, MQTT, SNMP) with TLS libraries available. The 80 MHz core maintains wire-speed packet handling on a 10/100 Mbps interface. 32 KB SRAM accommodates multiple sockets and packet buffers. The 100-pin TQFP provides dedicated Ethernet RMII/MII pins alongside SPI, UART, and I2C for RS-485 / sensor aggregation. Engineers can implement Modbus TCP to Modbus RTU bridges in a single chip.
Recommended
Motor Control (BLDC / Stepper)
The PIC32MX360F512LT-80V/PT's 80 MHz core, 5 timer/counter modules, and 8 PWM outputs (via OC modules) support sensor-based and sensorless BLDC motor commutation, plus stepper and brushed DC control. DMA-driven ADC measures back-EMF for sensorless trapezoidal commutation at up to 50 krpm. The 512 KB Flash accommodates full Microchip motor control libraries including field-oriented control (FOC). Hardware quadrature encoder interfaces on select timers handle closed-loop position control. The PT package's 85 I/O pins provide PWM, direction, fault, and brake signals plus USB/UART for configuration. The V-grade temperature rating handles motor-driver thermal environment.
Recommended
Portable Medical / Wellness Devices
The PIC32MX360F512LT-80V/PT powers portable medical and wellness devices such as blood pressure monitors, pulse oximeters, and clinical thermometers. The 10-bit ADC captures analog sensor signals from pressure bridges and thermistor/pulse-oximetry front-ends, while DMA continuously streams samples into the 32 KB SRAM. The 512 KB Flash hosts the application firmware, sensor calibration tables, and trend history logging. The 100-pin TQFP supports LCD/TFT displays via PMP for numeric and waveform visualization. USB Full-Speed enables direct connectivity to host PCs or chargers. The 2.3-3.6 V single-supply rail simplifies battery-powered designs using 2x AA or Li-ion cells.

Design Notes
PIC32MX360F512LT-80V/PT requires separate analog (AVDD/AVSS) and digital (VDD/VSS) supply pairs. Place 10 uF + 0.1 uF decoupling on each VDD pin (multiple VDD pins exist around the package) and a 10 uF + 0.1 uF on AVDD. Trace usage between VDD and AVDD should be avoided - keep them connected only at a single point near the voltage regulator. The internal 1.8 V core regulator requires a 4.7 uF capacitor on the VCAP pin for stability.
Route the 80 MHz CPU clock trace as short as possible with controlled impedance, and surround it with ground for signal integrity. The USB D+/D- pair (RG2/RG3) requires 90 ohm differential impedance matching per USB 2.0 specification. Place the 27 ohm series termination resistors close to the MCU pins. For Ethernet RMII, the 50 MHz reference clock trace should be length-matched with the data lines within 50 mils.
Configure the JTAG pins (TCK/TMS/TDI/TDO at pins 97-100) for alternate GPIO use via the JTAGEN bit in the DEVCFG0 configuration register - if disabled accidentally, programming requires a high-voltage ICSP recovery sequence. Also configure the ENVREG pin (pin 17) to enable the internal 1.8 V regulator; leaving it floating causes erratic behavior. Brown-out resets should be enabled in DEVCFG1 to prevent Flash corruption during power glitches.
Estimated: At 80 MHz full CPU load with all peripherals active, core power dissipation is approximately 150 mW. Junction-to-ambient thermal resistance of the 100-pin TQFP (12x12 mm) is roughly 50 C/W, giving a 7.5C rise above ambient. For designs operating at high ambient (>70C) with continuous 80 MHz operation, ensure adequate PCB copper area (at least 1 square inch ground pour) underneath the package to stay within the 125C junction limit.
