PIC32MX370F512LT-V/PT 개요
A 32-bit microcontroller (microcontroller unit, MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile working memory, and a configurable set of digital and communication peripherals. The PIC32MX3/4 family sits in the broader taxonomy of PIC32 microcontrollers -> 32-bit microcontrollers -> microcontrollers -> microcontrollers and processors -> semiconductor. MIPS-based PIC32 devices share the Harvard architecture heritage of the PIC family while adding a 32-bit data path, 32-bit registers, and deterministic interrupt latency that make them well suited to real-time embedded control.
Key features include 512 KB Flash, 128 KB SRAM, 4 KB EEPROM, a 10-bit ADC capable of up to 1 Msps, five 16-bit timers/counters, two comparators, two SPI/I2S, two I2C, and USB 2.0 full-speed device/host/OTG. The core executes most instructions in one cycle, delivering up to 1.50 DMIPS/MHz, or about 120 DMIPS at 80 MHz. The 100-pin TQFP exposes up to 83 I/O pins and supports 5V-tolerant inputs.
Typical applications include industrial automation and control panels, USB-equipped embedded peripherals, graphical HMI front panels driving small LCDs, consumer audio accessories that leverage the I2S peripherals, and ruggedized IoT edge nodes that need industrial temperature endurance. The combination of USB, a 28-channel ADC and a generous pin count makes this part particularly useful as a single-chip supervisory controller for mixed-signal boards.
When designing with this device, place a 1uF decoupling capacitor on each VDD/VDDCORE pin pair and route the analog AVSS/AVDD traces away from switching nodes to keep ADC noise low. The trace pins (TRCLK, TRD0..3) are optional and should be grounded if unused; the JTAG TMS/TCK/TDO/TDI pins are likewise optional for production programming via ICSP.

설계 노트
Place a 1uF decoupling capacitor within 5 mm of every VDD/VDDCORE pin pair, plus a 10uF bulk capacitor on the main 3.3V rail. The PIC32MX370 internal 1.8V LDO powers the core from VDD; no external core supply is required for production parts. Use a ferrite bead to isolate AVDD from VDD if ADC noise exceeds 1 LSB.
Estimated: at 80 MHz with peripherals active, core current draw is approximately 35-45 mA at 3.3V. The 100-pin TQFP package has theta_JA around 40 C/W on a standard 4-layer JEDEC test board, so continuous 45 mA (about 150 mW dissipation) yields a 6C junction temperature rise. No heatsink is needed for normal operation; derate CPU speed above 70C ambient if tight timing budgets are required.
Route the USB DP/DN traces as a 90-ohm differential pair on the top layer, with continuous ground reference underneath. Keep analog AVDD/AVSS traces away from switching nodes and PWM outputs to minimize ADC noise coupling. Reserve a footprint for a 32.768 kHz crystal on SOSCO/SOSCI if RTC accuracy is needed; otherwise ground both pins and use the internal RC oscillator.
Do not leave the MCLR pin floating - it must be tied to VDD through a 10 kohm resistor with a 100 nF cap to ground for reliable reset. The JTAG TMS/TCK/TDO/TDI pins default to alternate functions after reset; if unused, configure them as outputs and leave them disconnected. Programming via ICSP requires PGECx/PGEDx pins to remain accessible on the final PCB.
Locate the parallel master port (PMP) data/control pins in a contiguous group on the PCB to simplify routing to the TFT/LCD connector. Place a 4.7k pull-up on SDA and SCL if I2C peripherals are present. For USB-OTG applications, add a 10uF bulk capacitor on VBUS and a current-limiting FET on the host VBUS output per USB 2.0 spec.
