PIC32MX440F256HT-80V/PT Descripción general
A PIC32 microcontroller is a 32-bit MCU based on the MIPS32 M4K core architecture, positioned above 8/16-bit families in performance and below ARM Cortex-M series in cost. The PIC32MX family integrates rich peripherals such as USB, CAN, and PMP in single-chip packages, enabling direct USB-host/device connectivity without external bridges.
Key features of the PIC32MX440F256HT-80V/PT include 256 KB Flash with 32 KB RAM, 16-bit parallel master port (PMP) for external bus interfaces, up to 5 timers, 2 I2C, 2 SPI, and 2 UART channels. The integrated full-speed USB 2.0 OTG controller with on-chip transceiver eliminates external PHY chips. With 1.56 DMIPS/MHz performance and single-cycle multiply/divide, it executes DSP-like routines efficiently for general-purpose and control applications.
The device runs from 2.3V to 3.6V with 5V-tolerant digital inputs and integrates a 10-bit 1 Msps ADC with up to 16 channels. The 80 MHz core, MIPS M4K pipeline, and 32 KB RAM allow mid-range RTOS execution or complex state-machine firmware without external SRAM.
Typical applications include USB peripherals (barcode scanners, custom HID, data loggers), industrial control PLCs, low-end HMI panels with PMP-driven LCD, embedded motor control, and consumer audio devices. The USB-OTG feature particularly fits point-of-sale terminals, USB-to-UART converters, and device-mode test instrumentation. The wide operating temperature and robust peripheral set also suit industrial automation, building automation, and medical device peripherals.
When designing with this MCU, allocate the 16 KB of boot Flash region reserved by Microchip's firmware update library. Place a 12 MHz crystal with appropriate load capacitors and provide adequate decoupling near VDD/VSS pins. Use the device's internal LDO if 5V-tolerant I/O is required.

Notas de diseño
The PIC32MX440F256HT-80V/PT operates from 2.3V to 3.6V on VDD pins, with dedicated VDDCORE pins for the internal regulator that supply the CPU core. Place a 10 uF bulk capacitor and 0.1 uF decoupling capacitors adjacent to each VDD/VSS pair, particularly near the high-current USB pins. Estimated: peak current consumption at 80 MHz with USB active is approximately 60-80 mA, requiring attention to PCB power-trace widths.
Reserve 4 KB of Flash for Microchip's bootloader library when designing firmware-upgradeable products. Configure the JTAG/TRACE pins (PGECx/PGEDx) correctly during PCB layout to avoid debugger lock-out. The 16-bit PMP requires careful PCB routing to maintain signal integrity for external LCD interfaces; keep traces under 50 mm and isolate from noisy switching nodes. Note: PIC32MX440F256HT-80V/PT differs from -80I/PT only in temperature grade; choose the correct suffix for your operating environment.
Route the USB D+/D- traces as a 90-ohm differential pair with no stubs or test points, matching the on-chip transceiver requirements per Microchip datasheet DS61143H. Keep the 12 MHz primary oscillator traces short and surround them with a ground guard ring. Place the analog AVSS/AVDD pair with its own ferrite bead to isolate ADC reference noise from digital switching. The 64-TQFP package has multiple VDD/VSS pairs; ensure each pair has its own decoupling capacitor as close to the pin as physically possible.
At 80 MHz operation with USB active and moderate GPIO toggling, the device dissipates approximately 250-400 mW. The 64-TQFP package has a thermal resistance of approximately 35-40 C/W theta_JA, allowing operation up to 105C junction without a heatsink. Estimated: at 25C ambient, junction temperature rises approximately 10-15C above ambient at full operation. For sealed enclosures, validate thermal performance with a thermocouple on the package top during worst-case duty cycle.
