PIC32MX110F016DT-V/ML 概述
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and programmable peripherals. The PIC32MX family belongs to the broader class of 32-bit microcontrollers, which sit between 8/16-bit MCUs (used for simple control tasks) and high-end application processors (used for operating systems and rich UI). The MIPS32 M4K core used in this part supports MIPS16e mode for up to 40% smaller code size, reducing Flash footprint for compact embedded applications. Within Microchip's portfolio, the PIC32MX1x0 series is positioned as an entry-level 32-bit MCU for cost-sensitive designs.
Key features of the PIC32MX110F016DT-V/ML include hardware DMA with up to four channels and automatic data size detection, separate PLLs for CPU and USB clocks, configurable WDT with an on-chip low-power RC oscillator, and multiple power management modes for energy-constrained designs. The operating temperature range is -40 °C to +105 °C (grade -V), making it suitable for industrial environments. The QFN-44 package exposes a thermal pad that should be soldered to the ground plane to lower thermal resistance.
Architecturally, the device pairs the M4K pipeline with a dedicated peripheral bus, allowing DMA-driven I/O without CPU intervention. PPS allows most digital peripherals to be remapped to a wide range of I/O pins, simplifying PCB routing. CTMU enables reliable capacitive touch sensing using a constant-current source and timer capture, eliminating external touch ICs.
Typical applications include consumer electronics with graphical user interfaces using the PMP, USB device/host peripherals (where USB is present in this family), industrial control panels, capacitive touch user interfaces, and low-cost IoT sensor nodes. The combination of small Flash, moderate SRAM, and rich peripherals makes it a common choice for bridging 8-bit PIC users to 32-bit performance.
When designing with this part, allocate the QFN exposed pad to a continuous ground copper pour with multiple thermal vias for best thermal and electrical performance. Configure PPS carefully during firmware bring-up because mis-mapped peripherals can appear as silent failures. For USB applications, ensure the 48 MHz PLL is correctly tuned and the USB transceiver bypass capacitors follow the reference design.

典型应用
PIC32MX110F016DT-V/ML 适用于 6 应用s: USB Device Peripherals, Capacitive Touch User Interfaces, Industrial Control Panels with PMP Graphics, Low-Cost IoT Sensor Nodes, Audio Codec Interfaces (I2S), Automotive Body Electronics (Grade -V).
USB Device Peripherals
The PIC32MX110F016DT-V/ML is well-suited for USB Full-Speed device peripherals such as HID-class input devices, CDC virtual COM ports, and custom bulk/interrupt endpoints. Its on-chip USB transceiver and dedicated 48 MHz PLL eliminate the need for an external crystal, reducing BOM cost for keyboards, custom HID controllers, and USB-to-UART bridges. PPS allows the D+/D- lines and VBUS sense to be routed to convenient package pins. Compared to a software-bit-banged USB solution on an 8-bit MCU, the integrated peripheral offloads the CPU and frees MIPS for the application layer, while 4 KB SRAM is enough for typical class stacks.
推荐
Capacitive Touch User Interfaces
The integrated Charge Time Measurement Unit (CTMU) and mTouch library make the PIC32MX110F016DT-V/ML a strong fit for capacitive touch buttons, sliders, and proximity sensors in appliance and consumer products. CTMU provides a constant current source and timer capture mechanism that reliably resolves small capacitance changes, supporting reliable touch through up to 5 mm of plastic overlay. With 16 KB Flash, designers can implement 8-16 touch channels plus a UART command interface. Lower active current (under 0.5 mA/MHz) and multiple power management modes help battery-powered remote controls and IoT wall switches meet energy budgets.
推荐
Industrial Control Panels with PMP Graphics
The Parallel Master Port (PMP) peripheral allows the PIC32MX110F016DT-V/ML to drive small parallel TFT or OLED displays without an external graphics controller, enabling compact HMI panels for industrial machines. PMP supports 8-bit or 16-bit data and a configurable address bus, fitting common 320x240 resolution panels. The 40 MHz MIPS M4K core is sufficient for menu rendering, real-time control loops, and Modbus RTU over UART. PPS ensures the data/control signals route cleanly to the connector, simplifying PCB layout. The -40C to +105C temperature grade suits factory-floor enclosures without additional thermal management.
推荐
Low-Cost IoT Sensor Nodes
For cost-sensitive IoT sensor nodes, the PIC32MX110F016DT-V/ML delivers 32-bit performance, integrated USB for commissioning, and 4 KB SRAM for small protocol buffers, all at under $2 per unit in volume. Designers can use UART to interface with sensors (temperature, pressure, flow) and I2C to attach digital sensors, while CTMU enables a touch-based user interface for configuration. The device's multiple power management modes (Idle, Sleep) drop quiescent current to the microamp range between measurements, enabling years of battery life on coin cells or 2x AA packs for wireless or wire-attached nodes.
推荐
Audio Codec Interfaces (I2S)
The two I2S/SPI modules on the PIC32MX110F016DT-V/ML enable direct interface to external audio codecs, supporting simple audio playback, recording, and tone generation for consumer devices and intercoms. With DMA, audio samples can stream without CPU intervention, leaving MIPS headroom for control logic. The 16 KB Flash budget is sufficient for compact audio prompt libraries, while 4 KB SRAM is adequate for short buffering. The exposed-pad QFN-44 package provides low thermal resistance when driving 8 ohm speakers through an external amplifier, suitable for kiosks and doorbells.
推荐
Automotive Body Electronics (Grade -V)
With its -V temperature grade (-40C to +105C) and AEC-Q100 qualification per the DigiPart listing, the PIC32MX110F016DT-V/ML is suitable for non-safety automotive body electronics such as interior lighting controllers, mirror adjusters, and seat controllers. Its USB capability enables factory programming/diagnostics, while CAN-style messaging can be implemented over UART with external transceivers. PPS simplifies PCB routing in space-constrained body modules, and the MIPS16e mode extends Flash for parameter storage. Designers should still consult the Microchip automotive design package for full AEC-Q100 collateral.

设计说明
The 44-pin QFN (8x8 mm) package relies on the exposed pad (EPAD) for both electrical ground and primary thermal conduction. Per the Microchip package guidelines, the EPAD must be soldered to a continuous ground copper pour with at least 9 thermal vias (0.3 mm drill, 1.0 mm pitch) directly under the pad. Skipping EPAD soldering degrades thermal performance and can cause intermittent reset behavior at high ambient temperatures.
Add a 100 nF decoupling capacitor within 2 mm of each VDD pin and a single 10 uF bulk capacitor on the regulator output rail. According to the Microchip PIC32MX1xx reference design, VUSB and VBUS sense pins require separate filtering; failure to follow the reference layout may cause USB enumeration failures. Power management modes (Sleep, Idle) drop quiescent current to the microamp range between events.
Peripheral Pin Select (PPS) is locked by default on most PPS-capable pins. Developers should unlock PPS via the IOLOCK bit sequence before remapping functions, and re-lock after configuration to prevent runaway code from changing peripheral mappings at runtime. A common pitfall is forgetting to remap the UART TX/RX after boot, leaving firmware stuck with no console output.
For USB applications, route D+ and D- as a 90 ohm differential pair with continuous ground reference on the layer below; keep total length under 50 mm where possible. The on-chip USB Full-Speed transceiver tolerates standard FR-4 stack-ups but is sensitive to stubs and excessive via transitions. According to Microchip's USB design checklist, place the 15 kohm pull-down on D- and 1.5 kohm pull-up on D+ (bus-powered) as close to the MCU as practical.
