A PIC32MX microcontroller is a MIPS-based 32-bit MCU that combines RISC pipeline performance with Microchip's well-established PIC ecosystem, MPLAB X IDE, and Harmony code-generation framework. Within the broader embedded hierarchy, PIC32MX sits between 8/16-bit PIC16/PIC24 MCUs and the higher-end Cortex-M based SAM/dsPIC families, offering a balance of computational throughput, integrated USB, and large memory for general-purpose and USB-enabled designs.
Key features of this part include 80 MHz maximum operating frequency, 128 KB Flash (128K x 8), 32 KB SRAM, integrated Full-Speed USB OTG with transceiver, up to 16 ADC channels at 10-bit resolution, multiple serial interfaces, and wide operating voltage support of 2.5 V to 3.6 V. The 121-pin TFBGA exposes the maximum peripheral count of the family, including 85+ digital I/O and dedicated USB D+/D- lines.
Architecturally, the PIC32MX4XX family uses the MIPS32 M4K core with hardware multiply/divide, single-cycle 32-bit ALU, and pre-fetch cache for deterministic Flash execution. The USB OTG block includes the physical transceiver, PLL, and full OTG state machine, eliminating external PHY components. Memory is organized with a 32-bit Flash prefetch module and a separate 32 KB SRAM bank for buffered USB and DMA operations.
Typical applications include USB peripherals (HID, CDC, MSD), industrial control interfaces, low-cost audio devices, sensor hubs with USB diagnostics, and embedded graphics with PMP. Designers also use PIC32MX440F128L in USB-OTG dual-role designs where the device must act as both host and peripheral.
When designing with this part, ensure that the 121-pin TFBGA PCB layout can accommodate 0.65 mm pitch BGA escape routing with proper via-in-pad or microvia stack-up. The internal 8 MHz oscillator with PLL must be configured for the 80 MHz operation, and the USB bus requires a 48 MHz reference derived from the system PLL.

Ứng dụng tiêu biểu
PIC32MX440F128L-80V/BG phù hợp cho 7 Áp dụngs: USB HID Peripheral Device, USB CDC Virtual COM Port Bridge, Industrial Sensor Hub with USB Diagnostics, Embedded Audio with USB Streaming, USB MSD (Mass Storage) Device, USB OTG Dual-Role Device (DRD), Graphics PMP Display Controller.
USB HID Peripheral Device
The PIC32MX440F128L-80V/BG fits USB HID peripherals thanks to its integrated USB 2.0 Full-Speed OTG controller with on-chip transceiver and 80 MHz core for HID report parsing. With 128 KB Flash, full HID stack plus custom report descriptors fit comfortably, while 32 KB RAM holds double-buffered EP1/EP2 endpoints for low-latency interrupt IN transfers. The -40C to +105C operating range also lets the same firmware serve industrial HMIs and consumer keyboards/mice. The chip is placed as the device-side controller on the USB bus; only an external ESD array (e.g., USBLC6-2) and a 12 MHz crystal or internal 8 MHz + PLL are needed.

USB CDC Virtual COM Port Bridge
For USB-to-UART bridges and CDC virtual COM ports, the PIC32MX440F128L-80V/BG's 80 MHz MIPS core delivers full 12 Mbps USB throughput without CPU bottleneck, and 32 KB RAM is enough for a ring-buffered UART at 921600 baud with CDC echo. Compared to external FT232-class bridges, this design eliminates a separate IC and BOM cost while keeping the firmware stack inside the same MCU as the rest of the product. Place the chip on the device side of the USB cable and route D+/D- as 90 ohm differential pair per USB 2.0 spec; consider adding ferrite beads if the product must pass EN 55022 radiated emissions.

Industrial Sensor Hub with USB Diagnostics
Industrial sensor hubs use the PIC32MX440F128L-80V/BG to aggregate analog/digital sensor data via the on-chip 10-bit ADC and I2C/SPI peripherals, then expose the data through USB for diagnostics. The 80 MHz core runs a small RTOS or scheduler with sub-millisecond task latency, while the 121-TFBGA package exposes 85 I/O for multi-channel sensor wiring. Compared to a Cortex-M0+ design, the PIC32MX wins on raw DMIPS per mA and on having the same die serve both the field network and the USB diagnostic port, reducing part count on the factory-floor BOM.

Embedded Audio with USB Streaming
Low-cost USB speakers and headsets use the PIC32MX440F128L-80V/BG as a USB isochronous audio sink with software sample-rate conversion to drive an external DAC or PWM amplifier. The 32 KB SRAM is tight but sufficient for stereo 48 kHz 16-bit isochronous endpoints with single-buffered USB descriptors; consider PIC32MX460F256L if you need software SRC or DSP. Place the chip between the USB connector and the audio DAC, with the PIC32 handling HID volume controls, descriptor parsing, and silent-USB-PLL configuration. Compared to dedicated USB audio chips like PCM2704, this design adds vendor HID control flexibility but requires the developer to implement the USB audio class.
Được đề xuất
USB MSD (Mass Storage) Device
USB mass-storage devices that expose SD cards or internal Flash over USB use the PIC32MX440F128L-80V/BG for SCSI-class handling plus FAT/FS stack from Microchip's MDD library. The 80 MHz core can sustain typical SD read throughput (~5 MB/s) while USB bulk transfers handle the host side; 32 KB RAM is sufficient if LBA caching is kept modest. Place the chip as the bridge between the SD/SPI peripheral and the USB BULK-only endpoint, with a level shifter if the SD card runs at 3.3 V only. Compared to commercial USB-SD bridge ICs, the PIC32MX adds user-configurable vendor commands and OTA firmware upgrades.
Được đề xuất
USB OTG Dual-Role Device (DRD)
DRD products like USB-OTG flash drives and dual-role data loggers use the PIC32MX440F128L-80V/BG to switch between host and device modes using the integrated OTG state machine. The on-chip transceiver plus 5 V-tolerant VBUS pin and charge-pump support lets the chip assert VBUS for downstream ports when acting as host. With 128 KB Flash, the SRP/HNP/ADP protocols plus a small file-system stack fit without external memory. Place the chip with two USB ports (mini-AB or USB-C with role-detect), each guarded by an ESD array; note that the 80 MHz USB clock must derive from the 48 MHz PLL per the PIC32MX USB chapter.
Được đề xuất
Graphics PMP Display Controller
Cost-sensitive HMIs and low-resolution TFT displays use the PIC32MX440F128L-80V/BG as a graphics controller over the Parallel Master Port (PMP) peripheral. The 80 MHz core refreshes 320x240 QVGA panels at 30+ FPS from a frame buffer in 32 KB RAM, or pages from external SPI Flash for larger bitmaps. Compared to higher-end PIC32MZ designs, the PIC32MX440 fits designs where under 50,000 pixels with limited animation are acceptable. Place the chip driving a PMP-attached TFT with backlight PWM on a 16-bit timer, and use the 10-bit ADC for touch-screen resistive sensing.

Ghi chú thiết kế
The 121-TFBGA uses a 0.65 mm pitch with balls on a 10x10 mm grid. Use 4-layer PCB stack-up with the inner layers as GND and power planes for via-in-pad escape routing. Microvia or via-in-pad technology is strongly recommended at the outer row of balls to route out signals cleanly. Maintain differential impedance of 90 ohm on the USB D+/D- pair with 5 mil trace width and 6 mil spacing on a 4 mil dielectric per the USB 2.0 specification.
Estimated: at 80 MHz core, VDD 3.3 V, and 75% peripheral activity, typical current consumption is ~70 mA. Add a 100 nF decoupling capacitor on each VDD/VSS pin pair, plus a 4.7 uF bulk capacitor within 1 cm of the supply pins. The VUSB3V3 pin needs a 0.1 uF + 4.7 uF cap pair to provide clean bias for the on-chip USB transceiver. AVDD must be tied to VDD with its own 10 uH ferrite-bead + 100 nF cap network to keep ADC noise below 2 LSB at 10-bit resolution.
The TFBGA package has a typical theta_JA of about 32 C/W for the 121-ball 10x10 mm variant. Estimated: at the worst-case 80 MHz full-load condition (~80 mA * 3.3 V = 264 mW), junction temperature rise is roughly 8C above ambient with proper PCB thermal vias under the center balls. For industrial designs at +105C ambient, derating to 60 MHz keeps the junction below 110C and improves long-term reliability.
Do not skip the MCLR pull-up resistor (typically 10 kOhm) - the PIC32MX will not exit reset without it. The USB module requires a 48 MHz reference clock derived from the system PLL via the UPLL peripheral; routing the wrong reference will cause USB enumeration failures. The PGED1/PGEC1 (or PGED2/PGEC2) pair must be brought out to a 2x3 or 1x6 0.1 inch header for ICSP programming; do not route these as long traces. Finally, ensure VSS pins total at least 15 balls (out of 121) are soldered for adequate ground current return.
