PIC32MX110F016B-I/ML Übersicht
A microcontroller (MCU) is a programmable system-on-a-chip that integrates a CPU core, memory, peripherals, and I/O into a single device. PIC32MX MCUs sit in the broader hierarchy of embedded microcontrollers -> 32-bit MCUs -> MIPS-based MCUs -> Microchip PIC32 family -> semiconductor IC. They are designed to deliver deterministic real-time control with higher throughput than 8/16-bit parts while retaining the peripheral-rich architecture familiar to PIC users.
Key features of the PIC32MX110F016B include Peripheral Pin Select (PPS) for flexible pin assignment, two I2S/SPI modules for codec and serial connectivity, a Parallel Master Port (PMP) for graphics interfaces, a Charge Time Measurement Unit (CTMU) supporting mTouch capacitive touch buttons/sliders, four DMA channels, and a 10-bit ADC capable of up to 1 Msps. The MIPS32 M4K core delivers 1.56 DMIPS/MHz and executes most instructions in a single cycle, making it suitable for control loops and modest DSP-style signal processing.
Typical applications include consumer electronics with graphical displays, capacitive touch human-machine interfaces, USB/audio accessories, sensor hubs, industrial control nodes, and low-cost IoT endpoints that need 32-bit performance without the cost of Cortex-M parts. The 28-QFN footprint suits space-constrained PCB designs such as wearable bands and remote-control modules.
When designing with the PIC32MX110F016B-I/ML, ensure the exposed pad is soldered to a sufficient copper pour for thermal and electrical grounding, and respect the supply-voltage range of 2.3 V to 3.6 V across all operating modes including programming. Use MPLAB X IDE with XC32 compiler for development; ICD programming requires dedicated PGECx/PGEDx pin pairs and decoupling on every VDD pin.

Typische Anwendungen
PIC32MX110F016B-I/ML ist geeignet für 7 Anwendungs: Capacitive Touch HMI Panels, Consumer Audio Accessories, Industrial Sensor Hubs and IoT Edge Nodes, USB Human Interface Devices (HID), Small Graphic LCD Interfaces via PMP, Battery-Powered Remote Control Modules, Motor Control and PWM Drive.
Capacitive Touch HMI Panels
The PIC32MX110F016B-I/ML's integrated CTMU (Charge Time Measurement Unit) supports Microchip's mTouch capacitive-touch firmware for buttons, sliders, and proximity sensors, eliminating the need for an external touch controller IC. With 21 GPIO and 4 DMA channels, the device can scan multi-key touch panels while dedicating CPU cycles to HMI logic. The 40 MHz MIPS32 M4K core provides the deterministic timing needed for reliable touch acquisition, and the 28-QFN footprint suits compact front-panel PCBs. Typical design pairs the MCU with a segmented LCD driver and an LED backlight PWM channel for a complete user interface.
Empfohlen
Consumer Audio Accessories
Two I2S/SPI interfaces and a Parallel Master Port (PMP) let the PIC32MX110F016B-I/ML drive audio codecs and small graphic LCDs in speaker docks, headphone amplifiers, and Bluetooth audio remote controls. The MIPS32 M4K at 40 MHz delivers ~62 DMIPS, sufficient for sample-rate conversion, basic DSP effects, and protocol handling over UART/I2C. The 4 KB SRAM is enough for small audio buffers when paired with an external CODEC that handles its own memory. Designers benefit from MPLAB X IDE support and the PIC32's mature peripheral libraries for I2S configuration.
Empfohlen
Industrial Sensor Hubs and IoT Edge Nodes
With a 10-bit ADC capable of 1 Msps across 13 channels, the PIC32MX110F016B-I/ML can aggregate multiple analog sensors in industrial monitoring nodes without external ADC ICs. The 32-bit core runs Modbus/RTU, CAN-friendly firmware, and lightweight TCP/IP stacks via the UART and I2C peripherals, while 4 DMA channels offload data movement to keep the CPU free for control loops. Industrial -40C to +105C temperature rating suits factory floor deployment. PCB layout uses the 6x6 mm QFN with a generous ground pour for noise immunity in electrically noisy cabinets.
Empfohlen
USB Human Interface Devices (HID)
Although the PIC32MX110F016B base variant lacks USB-OTG, the pin-compatible PIC32MX130F/150F/170F siblings add full-speed USB and are drop-in replacements on the same 28-QFN (ML) footprint. This makes the 28-QFN (ML) land pattern ideal for designs that need a USB-less baseline today with a USB upgrade path tomorrow. The 40 MHz core handles HID class drivers and interrupt latency well. Using the same PCB for HID-only and HID+USB variants reduces tooling cost.
Empfohlen
Small Graphic LCD Interfaces via PMP
The Parallel Master Port (PMP) peripheral drives small TFT or STN graphic displays directly from the PIC32MX110F016B-I/ML, eliminating the need for an external display controller in cost-sensitive products. PMP can address up to 33 KB of external memory-mapped space, suitable for monochrome graphical menus. Combined with 4 KB SRAM for frame buffering and the 32-bit MIPS core for text rendering, this delivers a usable UI subsystem under USD 3 in BOM. Industrial temperature grade suits outdoor or in-vehicle display modules.
Empfohlen
Battery-Powered Remote Control Modules
Operating from 2.3 V to 3.6 V and consuming less than 0.5 mA/MHz active, the PIC32MX110F016B-I/ML is well suited for battery-powered remote controls, security keyfobs, and RF sensor end-nodes. The 28-QFN footprint fits in compact enclosures, and Sleep/Idle modes extend battery life when paired with RTCC wake events. The CTMU can also be repurposed for capacitive proximity wake-up. Code size stays modest thanks to the MIPS efficiency of 1.56 DMIPS/MHz, leaving room for application code in 16 KB Flash.
Empfohlen
Motor Control and PWM Drive
Five 16-bit timers plus two 32-bit timers give the PIC32MX110F016B-I/ML the PWM channels needed for brushed DC, stepper, or small BLDC motor control in appliance and hobby applications. The 40 MHz MIPS core executes PID loops at high update rates, while the 10-bit ADC samples back-EMF or current-sense signals from up to 13 channels. Peripheral Pin Select (PPS) makes it easy to route PWM outputs to any available GPIO. Designers typically pair the MCU with gate drivers and a small power stage on the same PCB.

Designhinweise
The 28-QFN (ML) package has an exposed thermal pad that must be soldered to a ground copper pour with multiple thermal vias for heat dissipation. The PIC32MX110F016B-I/ML active current is below 20 mA at 40 MHz, so self-heating is modest, but the exposed pad also serves as the primary electrical ground reference. Recommended copper area is at least 100 mm squared on the top layer with 4-8 vias to the internal ground plane. Without proper soldering to the e-pad, latch-up risk and EMI performance both degrade.
Place one 0.1 uF ceramic decoupling capacitor within 3 mm of every VDD pin (pins 11, 17, 22) plus one bulk 10 uF tantalum or ceramic capacitor near the package. Keep the crystal oscillator traces short and symmetric with a guard ring to GND. Route PGECx/PGEDx programming pins to a dedicated header or test pad for in-circuit programming and debugging. Use the MPLAB ICD footprint reference from Microchip's development board schematics as a starting layout.
Do not exceed 3.6 V on VDD; the part is permanently damaged above ~4 V. The PGECx/PGEDx pairs must be used as matched pairs - if PGEC2 is the ICSP clock then ICSPDAT must be on PGED2. Configuration bits must be set correctly for oscillator selection, watchdog, and code protection, otherwise the device may appear 'bricked'. Avoid routing PWM outputs across analog input traces to minimize ADC crosstalk; the 10-bit ADC is sensitive to digital switching noise within 100 ns of sampling.
The 10-bit 1 Msps ADC benefits from a quiet analog supply. Use a ferrite bead or RC filter to isolate AVDD from digital VDD when noise is a concern. The CTMU operates by charging a known current into a touch capacitor; for accurate touch detection, ensure the touch sensor traces are guarded with a driven shield signal or proper grounding. PPS reassigns peripheral functions to GPIO, but reassignments on pins currently driving high-current loads can cause glitches during runtime reconfiguration.
