PIC32MX440F128LT-80I/BG Visão geral
An MCU (microcontroller) is a single-chip computer that integrates a CPU core, RAM, non-volatile program memory, and peripherals such as ADC, timers, and communication interfaces. In the embedded hierarchy, the PIC32MX sits at the 32-bit mid-range tier, between 8/16-bit MCUs (PIC16, PIC24) and higher-performance Cortex-M parts. It uses the MIPS32 M4K core - a Harvard-architecture 32-bit RISC processor with single-cycle multiply - and is positioned by Microchip as a bridge from 8/16-bit PIC designs to full 32-bit performance without giving up peripheral compatibility.
The device features 128 KB Flash (128K x 8) with self-programmability, 32 KB SRAM, an 80 MHz core with 50 MHz peripheral bus, an on-chip 10-bit 1 Msps ADC with up to 16 channels, two I2C, two SPI, two UART modules, five 16-bit timers/counters, an RTCC, and a USB-2.0 full-speed OTG transceiver with integrated PHY. The I/O count is 85, with 5V-tolerant digital pins. Power input range is 2.3V to 3.6V across industrial temperature (-40C to +85C).
The MIPS32 M4K core delivers 1.56 DMIPS/MHz, allowing the 80 MHz part to execute up to 125 DMIPS. The wide peripheral set (USB, CAN optional on family, PMP for graphics/parallel bus) and generous SRAM simplify USB-device, USB-host, and embedded-graphics designs. The integrated USB-OTG transceiver removes the need for an external PHY, saving BOM cost and PCB area in low-cost USB applications.
Typical applications include USB peripherals (Human Interface Devices, mass storage, virtual COM ports), embedded control with USB host for barcode scanners or keyboards, industrial sensors with USB diagnostics, low-cost graphics via PMP, and home automation bridges. The PIC32MX4 family is broadly deployed in educational, hobbyist, and low-volume industrial products thanks to MPLAB X IDE and Harmony framework support.
When designing with this device, ensure USB impedance-controlled traces (90 ohms differential) and a 12 MHz or 48 MHz crystal reference as required by the USB PLL. The 2.3V to 3.6V supply rules out direct 5V system rails without an LDO. The TFBGA-121 package (10x10 mm, 0.8 mm ball pitch) requires multi-layer PCB and BGA assembly capability - choose the LQFP package variant for hand-solder or low-layer prototypes.

Aplicações típicas
PIC32MX440F128LT-80I/BG é adequado para 6 aplicaçãos: USB Human Interface Device (HID), USB Mass Storage Device, Industrial USB Sensor Interface, Embedded Graphics with PMP, USB Host Barcode Scanner Bridge, USB-OTG Dual-Role Device.
USB Human Interface Device (HID)
The PIC32MX440F128LT-80I/BG fits USB HID peripherals because of its integrated USB 2.0 full-speed OTG transceiver with on-chip PHY, eliminating external PHY components and reducing BOM cost. The MIPS32 M4K core at 80 MHz delivers 125 DMIPS, easily handling USB HID report generation, debouncing, and LED/button matrix scanning in real time. At 2.3V to 3.6V supply it pairs with USB bus-powered designs via a 3.3V LDO. The 128 KB Flash hosts the Microchip USB stack plus HID report descriptors, while 32 KB SRAM buffers incoming USB packets without stalling the CPU. Designers use the part in keyboards, mice, game controllers, and custom HID peripherals.
Recomendado
USB Mass Storage Device
The 80 MHz MIPS32 M4K core and 32 KB SRAM of the PIC32MX440F128LT-80I/BG support USB mass storage class (MSC) implementations with SD card or NAND flash via PMP or SPI. The integrated USB-OTG PHY cuts external component count, while the 128 KB Flash stores the MSC stack, FAT driver, and command handler. Industrial-grade -40C to +85C operation lets the part sit inside ruggedized USB storage products. Combined with the on-chip 10-bit ADC, designers can also expose diagnostics over USB like supply voltage and temperature. Reference designs in MPLAB Harmony use this exact part as the controller for SD-card-based USB readers.
Recomendado
Industrial USB Sensor Interface
The PIC32MX440F128LT-80I/BG suits industrial USB sensor bridges because its on-chip 10-bit 1 Msps ADC, dual UART/SPI/I2C peripherals, and USB-OTG enable a single-chip bridge between legacy RS-485 or SPI sensors and a USB host. The 2.3V to 3.6V supply and industrial -40C to +85C rating handle factory-floor environments. With 128 KB Flash the part accommodates Modbus RTU translation firmware and USB CDC drivers, and the 32 KB SRAM buffers sensor frames before USB transmission. Designers use it for USB-to-sensor gateways, USB oscilloscope front-ends, and protocol analyzers that stream sensor data over USB.
Recomendado
Embedded Graphics with PMP
The PIC32MX440F128LT-80I/BG's Parallel Master Port (PMP) drives small TFT LCDs and OLED displays directly from the MCU, eliminating an external graphics controller IC. At 80 MHz the MIPS32 M4K core refreshes QVGA (320x240) panels at adequate frame rates, and 32 KB SRAM holds small frame buffers or tile maps. The integrated USB-OTG makes the device useful as a USB-connected HMI panel that receives configuration or touch events over USB. Designers use this combination for low-cost touch panels, USB-controlled appliances, and instrument front panels where the same MCU handles display, USB, and sensor I/O.
Recomendado
USB Host Barcode Scanner Bridge
The PIC32MX440F128LT-80I/BG acts as a USB host for HID barcode scanners because the integrated USB-OTG PHY supports host mode without external components. At 80 MHz the MIPS32 M4K parses HID input reports and forwards decoded scan data over UART, SPI, or a second USB-CDC virtual COM port to a downstream controller. With 128 KB Flash it fits Microchip's USB host stack plus application firmware, and the 32 KB SRAM queues multiple scan reports during peak arrival. The 2.3V to 3.6V supply is compatible with industrial point-of-sale systems. Reference designs target retail POS, warehouse sorting, and kiosk scanner interfaces.
Recomendado
USB-OTG Dual-Role Device
The PIC32MX440F128LT-80I/BG is ideal for USB-OTG dual-role products like USB disk-on-key printers, USB diagnostic tools, or USB charging controllers because the on-chip OTG PHY supports both host and device roles. The 80 MHz MIPS32 M4K core handles the role-swap HNP and SRP protocols without external logic, and 32 KB SRAM buffers USB transactions during role transitions. The 128 KB Flash fits the full Microchip OTG stack plus role-switch application code. Combined with the on-chip ADC and PMP, designers can also build USB-OTG instruments with display feedback for the user during host or device operation.

- Includes Parallel Master Port (PMP) for direct LCD interface (vs PIC32MX320F128LT-80I/BG (PIC32MX3 family))
- Industrial temperature rating suitable for factory environments (vs PIC32MX360F256L-80V/BG (extended temp))
Notas de projeto
Route the USB D+ (RB8) and D- (RB9) lines as a 90-ohm differential pair with controlled impedance to the USB connector. Keep the trace length match within 150 mil (about 4 mm) per Microchip's USB hardware design guide. Place the 12 MHz or 48 MHz crystal reference as close as possible to the OSC1/OSC2 pins with short, ground-guarded traces; a noisy crystal reference causes USB packet errors and link failures. Add ESD protection (USBLC6-2SC6 or equivalent) on the USB connector side and a 1 uF decoupling cap on VBUS for OTG detection reliability.
Estimated: At 80 MHz with all peripherals active, the PIC32MX440F128LT-80I/BG draws roughly 65 mA from a 3.3V supply, dissipating about 215 mW. Provide at least 4 VDD/VSS pairs (one per package quadrant) and place 100 nF ceramic decoupling caps on each VDD pin within 3 mm of the ball. Add a 4.7 uF bulk cap near the supply input. Use a low-dropout regulator like MCP1700-3302E for USB bus-powered designs to ensure clean 3.3V under transient loads. The 5V-tolerant I/O feature lets you interface 5V sensors directly without level shifters.
Do not confuse PIC32MX3 (USB device-only) with PIC32MX4 (USB-OTG) variants - both share the same TFBGA-121 pinout but the PIC32MX3 family lacks USB host/OTG support. If your design uses USB host mode, the PIC32MX320F128LT-80I/BG will NOT work as a substitute despite identical pinout. Also note that PIC32MX4xx parts do not include CAN - if you need CAN, step up to PIC32MX5xx or PIC32MX6xx family. The 'T' suffix indicates tape-and-reel; the part without 'T' ships in trays - both are electrically identical.
The 121-TFBGA package uses 0.8 mm ball pitch on a 10x10 mm substrate, which requires 4-layer or 6-layer PCB with microvia-in-pad or laser-drilled vias for reliable assembly. Per Microchip's package guidelines, the PCB land pattern must include non-solder-mask-defined (NSMD) pads for better joint reliability and thermal vias under the center balls to improve heat dissipation. Avoid placing components directly under the BGA on the opposite PCB side to allow for X-ray inspection after assembly.
