PIC32MX120F064H-V/PT Présentation
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals onto one die. The PIC32MX120 family belongs to the broader category of 32-bit microcontrollers, which sit above 8/16-bit MCUs in performance and target applications requiring complex math (DSP), large code footprints, or rich connectivity. Microchip's PIC32 family is built on the MIPS M4K core, offering deterministic performance, low interrupt latency, and a mature toolchain (MPLAB X, XC32). Automotive-grade parts such as the PIC32MX120F064H-V/PT are AEC-Q100 qualified and support extended temperature grades including -40C to +125C (Grade 1) and -40C to +150C (Grade 0) for under-the-hood deployments.
Differentiating features include Peripheral Pin Select (PPS) for flexible digital I/O remapping, a Parallel Master Port (PMP) with dual read/write buffers for graphics or external memory interfacing, USB 2.0 full-speed OTG, CAN 2.0B, and a 16-bit parallel master port. The CTMU block enables robust capacitive touch measurement without external circuitry, making the device well-suited for HMI panels. The 64-pin TQFP (10x10 mm) footprint is the same as many other PIC32MX1/2/5XX 64-pin family members, simplifying board reuse across the family.
Typical applications include automotive body and gateway controllers, HMI panels with capacitive touch, industrial sensor hubs, low-cost audio peripherals via I2S, USB devices, and CAN-connected ECUs. The combination of CAN, USB, PMP, and mTouch makes the part a versatile bridge MCU for infotainment, climate control, and lighting modules.
When designing with this device, ensure VDD decoupling is generous (100 nF + 4.7 uF per pin pair), the ICSP pins (PGECx/PGEDx) are accessible for production programming, and the Trace/JTAG pins are not left floating. The PPS feature requires careful peripheral mapping during code bring-up to avoid pin conflicts.

Applications typiques
PIC32MX120F064H-V/PT convient pour 6 applications: Automotive Body Controller, HMI Panel with Capacitive Touch, Industrial Sensor Hub, USB Peripheral Device, CAN-Connected ECU Node, Low-Cost Audio Peripheral.
Automotive Body Controller
The PIC32MX120F064H-V/PT is well suited for automotive body control modules thanks to its AEC-Q100 Grade 2 qualification, 64KB Flash for CAN/UART/LIN stack plus application logic, and CAN 2.0B controller with dedicated acceptance filters. Its operating temperature range of -40C to +105C covers under-dash and cabin environments without derating. The device's 10-bit ADC and CTMU block provide analog and capacitive touch sensing for switch panels and occupant detection. Connecting via CAN at 500 kbps alongside four UARTs (LIN-capable) supports typical body-network topologies while keeping BOM cost low.
Recommandé
HMI Panel with Capacitive Touch
The PIC32MX120F064H-V/PT's CTMU peripheral enables robust mTouch capacitive touch sensing without external circuitry, reducing BOM and PCB area. With 64KB Flash, designers can run a touch library plus graphics and communication stacks. The PMP peripheral with dual read/write buffers drives small TFT or segment LCDs efficiently. Combine this with the I2S peripheral to provide audio feedback or voice prompts. Operating from 2.5V to 3.6V and consuming low current, it fits battery-backed or USB-powered HMI modules in industrial or appliance environments.
Recommandé
Industrial Sensor Hub
The PIC32MX120F064H-V/PT's combination of CAN, USB, UART, I2C, and SPI provides a complete sensor-hub interface. The 10-bit ADC at 1 Msps and five 16-bit timers support high-speed analog sampling for pressure, flow, or vibration sensors. With 8KB SRAM and 64KB Flash, a FreeRTOS or Micrium uC/OS-II port fits comfortably. The PPS feature allows remapping peripherals to optimize PCB routing when sensor density is high. Industrial-grade builds can use the PIC32MX120F064H-I/PT, while automotive-deployable variants use the -V/PT grade.
Recommandé
USB Peripheral Device
The PIC32MX120F064H-V/PT integrates a USB 2.0 full-speed OTG controller with on-chip transceiver, removing the need for an external USB PHY and saving PCB area. 64KB Flash is sufficient to run Microchip's USB stack with CDC, HID, or MSD device classes, while 8KB RAM comfortably holds endpoint buffers and protocol state. At 5V-tolerant digital I/O via USB VBUS sensing, the device powers USB peripherals such as data loggers, configuration tools, and diagnostic interfaces. Add an external ESD protection array (such as USBLC6-2SC6) on D+/D- for robust field deployments.
Recommandé
CAN-Connected ECU Node
For distributed ECUs in automotive and industrial networks, the PIC32MX120F064H-V/PT pairs its CAN 2.0B controller with external transceivers like MCP2551 or MCP2562 to form a complete node. 64KB Flash accommodates the OBD-II stack, UDS, or CANopen profiles, and 8KB RAM is sufficient for most NodeID and PDO handling. With -40C to +105C operation, the part survives under-hood-adjacent environments in chassis modules. AEC-Q100 Grade 2 qualification simplifies automotive PPAP documentation.
Recommandé
Low-Cost Audio Peripheral
The PIC32MX120F064H-V/PT integrates two I2S peripherals, enabling direct connection to audio codecs for stereo playback or capture without external logic. The PIC32MX family supports Microchip's audio framework libraries, including sample-rate conversion and USB audio class. 64KB Flash stores audio effects or DSP routines, while 8KB RAM holds short sample buffers. For automotive infotainment peripherals (warning chimes, button-press tones) or consumer audio accessories, this part delivers DSP-capable performance at MCU pricing.

Notes de conception
Decouple each VDD/VSS pair with a 100 nF ceramic capacitor placed within 5 mm of the pin; add a bulk 4.7 uF to 10 uF tantalum or ceramic at the regulator output. According to Microchip PIC32MX1XX/2XX/5XX family datasheet section on power considerations, the USB VUSB pin requires a 1 uF to 10 uF decoupling cap and must NOT be left floating even when USB is unused - the internal 3.3V USB regulator must see a stable load. Estimated core current at 40 MHz with all peripherals enabled is approximately 30 mA plus I/O pin currents.
Keep the 64-pin TQFP (PT) thermal pad footprint clean - although PT does not have an exposed pad, route power traces (VDD/VSS) on outer layers with wide pours. Place the oscillator crystal within 5 mm of OSC1/OSC2 and guard it with a ground ring. Per the family datasheet, the ICSP pins (PGECx/PGEDx) must be brought out to a programming header for production programming. JTAG pins TMS/TCK/TDO/TDI/TRST should not be left floating when JTAG is unused; tie TMS and TRST to VDD via 10 kohm pull-ups.
Do not exceed absolute maximum ratings: VDD must stay within 2.3V to 4.0V (3.6V recommended for industrial, 3.6V also for AEC-Q100 Grade 2). The 'V' temperature grade is Grade 2 (-40C to +105C), NOT Grade 1 or 0 - do not use this part in under-hood or powertrain applications above +105C. The PPS feature requires explicit unlock sequence before peripheral remapping; if not configured correctly, peripherals will appear non-functional. Always set unused I/O to outputs (low) or inputs with pull-down to minimize current in sleep.
USB D+/D- traces must be 90 ohm differential, length-matched within 1 mm, and routed over a continuous ground plane. According to USB 2.0 design guidelines, place the USBLC6-2SC6 or similar ESD protection within 10 mm of the USB connector, and keep the VBUS sense line RC-decoupled to filter high-frequency noise. For CAN, keep TX/RX traces short and route away from switching signals; the MCP2551/MCP2562 transceiver should be within 50 mm of the bus connector to minimize reflections.
