PIC32MX370F512H-V/PT Descripción general
What is a PIC32MX3xx/4xx MCU? The PIC32MX370F512H belongs to Microchip's PIC32MX3/4 family of MIPS32 M4K-core microcontrollers that combine 32-bit performance (up to 150 DMIPS in the 120 MHz variants) with rich peripherals such as USB, CAN, and graphics-friendly PWM/timer subsystems. Within the broader taxonomy, this part sits under microcontroller (MCU) -> 32-bit MCU -> MIPS MCU -> PIC32 family -> PIC32MX3/4 sub-family, used in industrial automation, HMI (audio/graphics/touch), USB device/host, and advanced analog applications.
Key features that distinguish this variant include 512 KB Flash with 128 KB SRAM, two I2C ports, two SPI ports configurable as I2S for audio CODEC interfaces, two analog comparators with programmable reference, and a charge-time measurement unit (CTMU) for capacitive touch sensing. The device supports 4 DMA channels, parallel master port, and code-efficient MIPS16e mode that reduces code size by up to 40%. The MIPS M4K core delivers 1.56 DMIPS/MHz.
The architecture uses a Harvard-style 5-stage pipeline with single-cycle 32x16 multiply-accumulate and two-cycle 32x32 multiply hardware, enabling DSP-class signal processing. It also includes a 4-channel hardware trace module (TRD3-TRD0 + TRCLK) for real-time instruction trace when paired with a trace-enabled debugger.
Typical applications include industrial automation controllers, USB peripherals and HID devices, audio processing with external CODEC over I2S, HMI/touch panels, automotive body controllers (under -40C to +105C spec), and IoT edge nodes requiring secure boot and firmware update via USB. The 28-channel ADC also enables multi-sensor data acquisition.
When designing with this MCU, ensure decoupling capacitors are placed within 5 mm of each power pin and that the USB D+/D- traces are 90 ohm differential with matched length. Use the trace pins TRCLK/TRD0-TRD3 only for debug; do not assign them as GPIO in production firmware. Verified cross-reference data confirms drop-in compatibility with the same-package variants in the PIC32MX370 family (e.g., I-grade and 120 MHz speed grades).

Aplicaciones típicas
PIC32MX370F512H-V/PT es adecuado para 6 aplicacións: Industrial Automation Controllers, USB HID / CDC Peripherals, Audio Processing with External CODEC, Capacitive Touch HMI Panels, Automotive Body Controllers, IoT Edge Nodes with USB Firmware Update.
Industrial Automation Controllers
The PIC32MX370F512H-V/PT fits industrial automation controllers because its 80 MHz MIPS M4K core delivers 125 DMIPS while the -40C to +105C operating range handles factory-floor thermal stress. The 28-channel 10-bit ADC simultaneously samples multiple sensor inputs (temperature, pressure, flow), while two I2C buses interface to digital sensors and two SPI/I2S ports connect to display drivers or audio feedback modules. The 4 DMA channels offload high-throughput ADC-to-memory transfers, freeing the CPU for PLC ladder logic or motion control loops. Estimated interrupt latency is under 200 ns - sufficient for deterministic control. The 512 KB Flash accommodates full Modbus/ EtherCAT firmware stacks.
Recomendado
USB HID / CDC Peripherals
The integrated USB 2.0 Full-Speed Device/Host/OTG controller makes PIC32MX370F512H-V/PT ideal for USB HID keyboards, mice, CDC virtual COM ports, and mass-storage devices. The 80 MHz core provides ample bandwidth for HID report processing and bulk endpoint transfers, while 128 KB SRAM buffers USB descriptors and HID reports without CPU intervention. The two UART modules map cleanly to CDC ACM class bridges. Two DMA channels can service USB endpoints in parallel with application code, and the automotive-grade -V temperature range supports USB ports in vehicle cabins.

Audio Processing with External CODEC
The two SPI modules can be reconfigured as I2S interfaces, enabling direct connection to audio CODECs such as the TI PCM5101A or AKM AK4556. The PIC32MX370F512H-V/PT's 80 MHz core can run software MP3/AAC decoders or basic DSP filtering on 48 kHz stereo streams, while the 128 KB SRAM holds ~250 ms of 16-bit/48 kHz audio buffer. The CTMU and ADC can sample microphone inputs for beam-forming or noise-cancellation pre-processing. Estimated CPU load for 48 kHz I2S Rx/Tx loopback is about 30% of MIPS, leaving room for application logic.
Recomendado
Capacitive Touch HMI Panels
The CTMU (Charge-Time Measurement Unit) integrated in PIC32MX370F512H-V/PT simplifies capacitive touch sensing for HMI panels without external touch controllers. Combined with the 28-channel ADC and 51 GPIO, designers can implement up to 28 touch buttons or a small matrix touch panel using the mTouch framework. The 512 KB Flash stores graphics tables and touch calibration, while the PMP (Parallel Master Port) drives TFT LCDs up to QVGA resolution. The automotive -40C to +105C range makes it suitable for vehicle HMI and appliance front panels.
Recomendado
Automotive Body Controllers
The -V temperature grade (-40C to +105C) qualifies PIC32MX370F512H-V/PT for automotive body control modules including door modules, seat controllers, mirror adjusters, and lighting drivers. The 28 ADC channels read multiple position sensors and current shunts, while 5 PWM-capable 16-bit timers drive LED dimming, motor speed control, and mirror actuators. The USB port supports diagnostic firmware updates via OBD-II adapters, and 512 KB Flash fits AUTOSAR-lite and CAN-based body network stacks. The wide 2.5 V to 3.6 V supply tolerates 12 V battery transients when paired with proper front-end regulation.
Recomendado
IoT Edge Nodes with USB Firmware Update
The PIC32MX370F512H-V/PT powers IoT edge nodes that use USB for factory provisioning and firmware updates. The 512 KB Flash supports dual-image bootloaders, and 128 KB SRAM handles TLS handshake scratch buffers and MQTT message queuing. The two I2C and two SPI buses interface to Wi-Fi/BLE modules, sensors, and EEPROM storage. The 4 DMA channels enable background sensor logging while the CPU handles networking. The -40C to +105C range supports outdoor enclosures, while MIPS16e mode reduces Flash wear by compressing firmware images.

Notas de diseño
Place a 100 nF decoupling capacitor within 5 mm of every AVDD and VDD pin, plus a bulk 10 uF tantalum or ceramic at the regulator output. The PIC32MX370 has separate analog and digital supplies (AVDD/AVSS and VDD/VSS); AVSS and VSS must be connected at a single low-impedance point under the IC. Estimated: total inrush current at 80 MHz with all peripherals active is approximately 70 mA, so size the regulator for at least 100 mA continuous with adequate thermal margin.
Route the USB D+ and D- traces as a 90 ohm differential pair with matched length (within 150 mil / 4 mm) and keep them short and isolated from switching signals. The 48 MHz crystal traces must be short and guarded by a ground pour; use a crystal with <= 10 pF load capacitance and matching load caps within 2 mm of the OSC1/OSC2 pins. Estimated PCB cost adder for proper USB routing and decoupling is negligible vs. IC cost.
Do not assign the JTAG/trace pins TRCLK, TRD0-TRD3 as GPIO in production firmware - these pins are reserved for hardware trace and will be sampled at reset. Use the trace module only with a compatible debugger like MPLAB ICD 4. Also, ensure the AVDD and VDD rails are powered simultaneously within 50 ms of each other; large mismatches can trigger POR/BOR events. When using USB host mode, external 5 V VBUS switch and current-limiting are mandatory per USB 2.0 spec.
At 80 MHz with USB active and all peripherals running, the core consumes approximately 65 mA from 3.3 V. Estimated: P_total = 3.3 V * 65 mA = 0.21 W. The TQFP-64 package has theta_JA approximately 50 C/W on a 4-layer JEDEC test board, giving a junction-to-ambient rise of 10.5 C above ambient - well within the 125 C junction limit for the -V automotive grade.
Información de cumplimiento
RoHS and REACH compliant per Microchip product page. The -V temperature grade supports automotive environments but the part is not formally AEC-Q100 qualified - contact Microchip for automotive-grade PPAP documentation if required.
