PIC32MX440F128H-80V/PT - 80MHz MIPS32 128KB Flash MCU | Microchip
MPN: PIC32MX440F128H-80V/PT ✓ فعالPIC32MX440F128H-80V/PT نمای کلی
A PIC32 microcontroller is a 32-bit MCU based on the MIPS instruction set, sitting between 8/16-bit PIC MCUs and higher-end Cortex-M parts. In the broader taxonomy, a PIC32MX belongs to the PIC32 family -> 32-bit MCU -> microcontroller -> embedded processor -> semiconductor. The MX series specifically targets cost-sensitive applications that benefit from MIPS32 performance, large Flash/RAM, and integrated USB, while remaining code-compatible with the MPLAB XC32 toolchain and Harmony framework.
The PIC32MX440F128H-80V variant offers 128 KB Flash and 32 KB RAM, an 80 MHz core (105 DMIPS), and a peripheral set that includes five 16-bit timers, two I2C, two SPI, two UART, a parallel master port, and a 16-channel 10-bit ADC. The -80V temperature grade covers -40C to +105C industrial operation, and the -80I grade extends to +85C; both share the same 64-pin TQFP pinout, simplifying thermal derating decisions. The MIPS16e instruction mode reduces code size by up to 40%, and the single-cycle 32x32 hardware multiply and divide accelerate DSP-style loops.
Typical applications include USB HID/CDC peripherals, industrial control panels, medical device front-ends, sensor hubs with USB diagnostics, and low-cost audio interfaces. The integrated USB OTG PHY eliminates the need for an external transceiver, shrinking BOM and board area for USB dongles and embedded hosts. When designing with this part, place the 64-pin TQFP on a 4-layer PCB with a solid ground pour beneath the exposed pad to dissipate up to ~1 W dissipation at full 80 MHz operation; derate the system clock to 60 MHz if the application requires lower EMI or extended -40C to +105C operation.

USB HID Peripheral Device
The PIC32MX440F128H-80V/PT is an excellent fit for USB HID peripherals such as keyboards, mice, custom input devices, and USB-to-UART bridges. Its integrated USB 2.0 Full-Speed OTG PHY with on-chip transceiver eliminates external USB components, shrinking BOM and PCB area. With 80 MHz MIPS32 M4K performance delivering 105 DMIPS, the core handles HID class parsing, debounce algorithms, and LED animations with significant headroom; the dedicated USB DMA channel offloads packet movement from the CPU. Placed on a 64-pin TQFP layout with 4-layer PCB and 3.3 V LDO, designers get a USB-IF compliant HID device at minimal cost.

Industrial Control Panel HMI
The PIC32MX440F128H-80V/PT powers industrial HMI front-ends, operator panels, and instrumentation displays where its -40C to +105C operating range and integrated peripherals deliver strong value. The 16-channel 10-bit ADC with 1 Msps rate handles sensor conditioning and potentiometer input, while the Parallel Master Port drives TFT LCDs up to 16-bit parallel. Two UARTs, two SPIs, and two I2Cs connect to motor drivers, sensors, and isolated communication links. Pair the MCU with the same 64-pin TQFP footprint in a panel-mount enclosure and it survives factory-floor conditions while running a touch UI and Modbus RTU stack simultaneously.

USB-to-UART Communication Bridge
The PIC32MX440F128H-80V/PT's integrated USB 2.0 FS OTG PHY and dual UART peripherals make it ideal for USB-to-UART bridges, CDC virtual COM ports, and field-upgradeable industrial gateways. The dedicated USB DMA channel sustains 12 Mbps throughput without CPU intervention, while the 32 KB SRAM buffers full-speed UART traffic. Designers typically wire the part to RS-232/RS-485 transceivers, with isolation for industrial noise immunity. The same TQFP-64 footprint eases integration into existing serial-converter designs, and the 128 KB Flash holds USB stack plus application firmware for protocol conversion.

Medical Device Data Logger
The PIC32MX440F128H-80V/PT serves in portable medical devices such as glucose meters, pulse oximeters, and patient data loggers where USB connectivity simplifies bedside data transfer. Its 80 MHz MIPS32 core compresses and timestamps sensor data, while 32 KB SRAM accommodates rolling buffers for continuous monitoring. The USB OTG port enables tethered uploads to clinic computers without requiring a separate interface IC. A 64-pin TQFP PCB with proper EMI shielding and an isolated USB section meets IEC 60601 EMI margins for medical equipment. Pair with low-noise ADCs to capture bio-signals cleanly.

Sensor Hub with USB Diagnostics
The PIC32MX440F128H-80V/PT acts as a multi-sensor hub aggregating I2C/SPI sensor data and exposing diagnostics over USB. The dual I2C and dual SPI buses can address multiple sensors concurrently (temperature, humidity, motion, gas), while the USB OTG port streams diagnostic packets to a host PC at 12 Mbps. The 10-bit ADC and 16 channels support analog sensor inputs in industrial monitoring. The 64-pin TQFP and 3.3 V single-rail supply simplify enclosure design, and the part shares the same pinout across the PIC32MX4XX family for fast memory scaling.

یادداشت‌های طراحی
PIC32MX440F128H operates on a single 2.3-3.6 V rail with peak core currents up to ~70 mA at 80 MHz with USB active. Decouple each VDD/VSS pair (pins 10, 16, 30, 36, 46, 55) with a 100 nF ceramic cap placed within 5 mm of the pin. Add a bulk 10 uF ceramic or tantalum near the IC. For USB applications, the VUSB3V3 pin (50) requires its own 100 nF + 4.7 uF decoupling network for the internal PHY regulator. A low-noise LDO such as Microchip MCP1700 ensures clean analog/digital rail separation.
Estimated: At 80 MHz full CPU + USB active, total power dissipation is around 200 mW, giving a junction temperature rise of ~25C above ambient on a 4-layer PCB with adequate ground pour. The 64-pin TQFP exposed pad must be soldered to a top-layer ground copper pour of at least 100 mm^2 for thermal spreading. For industrial -40C to +105C operation, ensure ambient does not exceed 80C with this dissipation profile, or derate the CPU to 60 MHz to stay within thermal margins.
Route the USB D+/D- differential pair (pins 47-48) with 90 ohm differential impedance, matched length within 2 mm, and keep them away from switching signals. Place the crystal oscillator traces (OSC1/OSC2, pins 37-38) short and shield with ground pour to minimize EMI. Use the parallel master port pins (RE/RF/RG banks) for external memory or LCD, keeping trace lengths under 50 mm to avoid timing skew. Maintain a continuous ground plane on layer 2 beneath the TQFP footprint.
Do not confuse -80V (industrial -40C to +105C) with -80I (industrial -40C to +85C) when ordering - the wrong grade fails thermal qualification. Always configure the CONFIG bits for the right oscillator mode (HS vs XT vs EC) before locking the device. When enabling USB, ensure the VBUS pin is correctly biased and a 10 kohm pull-down is on D+ or D- per USB-IF requirements. Also verify the bootloader fuses if using a custom USB bootloader, since the PIC32MX4XX has multiple boot vector locations.
