MPN: PIC32MX370F512HT-V/PT ✓ AktifPIC32MX370F512HT-V/PT Ringkasan
A 32-bit microcontroller (MCU) is an integrated circuit that combines a 32-bit processor core, volatile and non-volatile memory, digital peripherals, and mixed-signal interfaces in a single package. The PIC32MX3/4 family belongs to the broader hierarchy of microcontrollers -> embedded microcontrollers -> MIPS-based MCUs -> Microchip PIC32 -> 32-bit MCU category, serving as the bridge between 8-bit PIC16/PIC18 designs and higher-end Cortex-M PIC32MZ parts. The MIPS32 M4K core in the PIC32MX370 executes the MIPS32 instruction set with single-cycle multiplication hardware.
Key features include 512 KB Flash supporting up to 100,000 erase/write cycles, 128 KB SRAM, two I2C and two SPI/I2S peripherals, two UART channels, five 16-bit timers/counters, five input capture and five output compare/PWM modules, parallel master port (PMP), and JTAG/ICSP programming/debug interface. The ADC supports 28 channels at 10-bit resolution with conversion rates up to 1 Msps. The integrated USB 2.0 full-speed device/host/OTG controller (on selected family members) eliminates external PHY requirements for low-cost USB applications.
The -V suffix denotes the V temperature grade (-40C to +105C), qualifying this part for industrial and automotive-comfort environments per Microchip's AEC-Q100-like qualification flow. The TQFP-64 (PT) package provides a 0.5 mm lead pitch and 10x10 mm body suitable for hand-solderable prototypes and high-volume SMT production. The -V/PT combination specifically targets industrial-grade applications where extended thermal range is required.
Typical applications include industrial control panels, USB audio interfaces, home automation gateways, HVAC controllers, low-cost HMI displays, and motor control boards. The 80 MHz core with hardware multiply/divide accelerates RTOS-aware firmware such as FreeRTOS, while the rich peripheral set reduces BOM cost by integrating ADC, comparators, and communication buses on-chip.
When designing with this part, allocate sufficient decoupling (100 nF per VDD pin plus bulk) and respect the 2.3V to 3.6V supply range. The 10-bit ADC performs best with a low-impedance source (< 5 kohm); add a unity-gain buffer when scanning high-impedance sensors. Programming/debug via MPLAB ICD 3 or MPLAB PICkit 4 over the ICSP 2-wire interface.

Aplikasi Umum
PIC32MX370F512HT-V/PT cocok untuk 7 aplikasis: Industrial Control Panel HMI, USB Audio Interface / DAC, HVAC / Building Automation Controller, Low-Cost Motor Control / FOC Drive, Home Automation Gateway, Low-Cost Graphical Touch HMI, Educational / Development Board MCU.
Industrial Control Panel HMI
The PIC32MX370F512HT-V/PT is well suited to industrial HMI panels where its 80 MHz MIPS32 M4K core drives graphic LCDs via the Parallel Master Port (PMP) at full DMA speed without bus contention. With 512 KB of Flash and 128 KB of SRAM, the MCU holds a multi-page UI bitmap plus a FreeRTOS kernel and TCP/IP stack (when paired with an external ENC28J60) for web-based diagnostics. The 28-channel 10-bit ADC reads potentiometer/sensor inputs at 1 Msps for real-time closed-loop control. The -V industrial temperature grade of -40C to +105C supports factory-floor mounting near variable-frequency drives, while the 2.3V-3.6V supply range tolerates noisy 24V-to-3.3V DC-DC rails.

USB Audio Interface / DAC
The PIC32MX370F512HT-V/PT's USB 2.0 Full-Speed device controller and two SPI/I2S peripherals enable USB-to-I2S bridge designs that stream audio at 44.1 kHz and 48 kHz without external PHY chips. The 10-bit DAC on chip drives headphone monitor outputs or line-level test tones, while the integrated 10-bit ADC handles input level metering. With 128 KB SRAM, designers can buffer at least 80 ms of 16-bit / 48 kHz stereo audio (about 15 KB), leaving room for the USB endpoint FIFO and control logic. The 80 MHz core keeps CPU headroom above 30% during full-duplex streaming, sufficient for volume control and LED VU-meter updates.

HVAC / Building Automation Controller
The PIC32MX370F512HT-V/PT fits rooftop HVAC controllers that must run a small PID loop every 10 ms while driving a graphic keypad, multiple relays, and a Modbus RTU link over UART. The two UART peripherals simultaneously handle Modbus master and a debug/console port; the two I2C buses connect to temperature/humidity sensors and EEPROMs. With 512 KB Flash, the firmware stores lookup tables for the compressor curve, fault history, and OTA bootloaders. The -V industrial temperature grade meets rooftop enclosure requirements of -40C to +105C, while the 53 GPIO pins in TQFP-64 drive triac optocouplers and 24V relay coils directly via external drivers.

Low-Cost Motor Control / FOC Drive
The PIC32MX370F512HT-V/PT drives sensored or sensorless BLDC/PMSM motors at low-to-mid power (up to a few hundred watts) using its five 16-bit timers, five output compare PWM channels, and 10-bit ADC for current sensing. Field-oriented control (FOC) loops at 20 kHz require execution inside 50 us, well within the 80 MHz core's 12.5 ns instruction cycle budget. The 28-channel ADC samples three phase currents plus DC-bus voltage simultaneously at 1 Msps when using DMA. Industrial V temperature grade supports motor bay mounting where ambient temperatures routinely reach 90C. Migration to PIC32MX470 (120 MHz) doubles the FOC loop headroom for higher-RPM motors.

Home Automation Gateway
The PIC32MX370F512HT-V/PT serves as a sub-gateway inside home automation hubs, bridging Wi-Fi (external ESP32/MRF24WG0MA) with wired KNX, Modbus, or 1-Wire sensor networks. Its 512 KB Flash accommodates a small embedded TLS client plus an MQTT-SN bridge, while 128 KB SRAM holds sensor queues and JSON parse buffers. Two I2C buses connect to multiple environmental sensors at 400 kHz without bus contention. The industrial -40C to +105C V temperature grade tolerates equipment-room ambient temperatures, and the TQFP-64 (PT) package provides mechanical reliability in long-life installations.

Low-Cost Graphical Touch HMI
The PIC32MX370F512HT-V/PT drives 320x240 QVGA TFT displays via the Parallel Master Port (PMP) running at 80 MHz, sufficient for button-graphic UIs at 30 fps without DMA starvation. The 10-bit ADC reads resistive touch-panel voltages, while the on-chip 10-bit DAC generates a backlight PWM reference when paired with an op-amp. With 512 KB Flash, designers can store multi-language assets, custom fonts, and an embedded WebKit-like renderer for simple SVG widgets. The V temperature grade supports enclosures mounted near ovens, boilers, or outdoor cabinets. Migration path: PIC32MX470 (120 MHz, same TQFP-64) for capacitive touch controllers and 480x272 WQVGA panels.

Educational / Development Board MCU
The PIC32MX370F512HT-V/PT is a popular choice for university curricula and PIC32MX training kits because it balances cost (~$6 at qty-1000), Flash size (512 KB), and a familiar Microchip MPLAB X IDE workflow. The 80 MHz core with hardware multiply/divide supports introductory RTOS labs (FreeRTOS port available) and DSP exercises such as FIR/IIR filters using the on-chip ADC at 1 Msps. The 64-pin TQFP package is breadboard-friendly when paired with breakout PCBs and exposes 53 GPIO pins for student projects. Compatibility with PICkit 4 and ICD 4 programmers plus the harmony framework accelerates lab setup.

Diferensiator Kunci
- Higher 80 MHz clock vs. PIC32MX270 family's 50 MHz ceiling (vsPIC32MX270F512LT-V/PT)
- Industrial -40C to +105C V temperature grade vs. I grade (vsPIC32MX370F512HT-I/PT)
- 128 KB SRAM vs. 64 KB on PIC32MX270 family (vsPIC32MX270F512LT-V/PT)
- Industrial V-grade vs. commercial I-grade when both share same silicon (vsPIC32MX370F512H-V/PT)
Catatan Desain
Estimated: the PIC32MX370F512HT-V/PT draws up to 70 mA active at 80 MHz with all peripherals enabled. Place a 100 nF ceramic decoupling capacitor within 3 mm of every VDD pin and a 4.7 uF bulk capacitor at the package entry. AVDD requires its own ferrite-bead-isolated rail and a 100 nF decoupling cap to AVSS. Add a 10 uF bulk on AVDD if driving low-impedance sensors. Brown-out reset (BOR) and Power-on Reset (POR) are enabled by default but should be retained in firmware for industrial designs.
The TQFP-64 package has theta_JA around 50 C/W on a 2-layer PCB without copper pour, dropping to ~30 C/W with a 1 square-inch copper pad under the exposed die region. At 80 MHz full-load active current of ~70 mA at 3.3 V, internal dissipation is approximately 230 mW, producing a 7C rise on a 4-layer board. For industrial -40C to +105C operation at 105C ambient, ensure junction temperature stays below 125C by either limiting duty cycle or adding bottom-side copper flooding.
Route the 80 MHz crystal traces (OSC1/OSC2) with a guard ground on both sides, keeping the traces < 5 mm long and away from switching signals. Place the 32.768 kHz secondary crystal (SOSC) for RTC close to SOSCI/SOSCO with its own ground return. USB DP/DM traces require 90 ohm differential impedance and a 47 nF AC-coupling cap on the device-side D+ line (when USB module is present). Keep ADC analog traces short and isolated from digital signals by a ground pour.
Estimated: do not configure ADC inputs shared with digital functions without disabling the digital input buffer (ANSx register) - leaving it enabled injects noise into the ADC conversion. Avoid using the Parallel Master Port (PMP) and the upper 16 ADC channels simultaneously because they share pins on TQFP-64. When migrating from PIC32MX270 to PIC32MX370, the wait-state configuration register WS bits must be set to 1 for 80 MHz operation; the default boot configuration works only up to 50 MHz.
