PIC32MX110F016DT-I/TL Overview
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile working memory (SRAM), and programmable peripherals on one die. Within the broader semiconductor taxonomy, the PIC32MX family sits between 8/16-bit legacy MCUs and high-end Cortex-M cores, targeting the "32-bit performance at near 16-bit cost" design point. The M4K core adds DSP-like arithmetic and Single-Cycle Multiplication to help audio and graphics signal processing without a dedicated DSP.
Key differentiating features of this part include two I2S/SPI modules for codec interfacing, Peripheral Pin Select (PPS) for flexible signal routing, a Parallel Master Port (PMP) for graphics displays, and a Charge Time Measurement Unit (CTMU) that enables Microchip's mTouch capacitive touch buttons and sliders. Five 16-bit general-purpose timers, up to four DMA channels with automatic data size detection, separate PLLs for CPU and USB clocks, and 21 general-purpose I/O pins complete the peripheral set.
The PIC32MX110F016DT-I/TL is specified for an industrial temperature range of -40C to +105C and operates from 2.3 V to 3.6 V. The 'T' code in the part number indicates tape-and-reel packaging, 'I' indicates industrial temperature grade, and 'TL' designates the 44-pin VFTLA package. The compact 6 mm x 6 mm 0.65 mm-pitch package with exposed thermal pad helps thermal dissipation and PCB density.
Typical applications include consumer audio accessories using I2S codecs, low-cost graphical user interfaces with PMP-driven LCDs, capacitive-touch user input panels leveraging CTMU, USB device peripherals using the on-chip USB peripheral and dedicated PLL, and general-purpose industrial control nodes that need 32-bit math at low BOM cost.
When designing with this part, remember that PPS remaps must be unlocked before use, and the 2.3 V minimum supply rules out 1.8 V-only rails. The exposed thermal pad should be soldered to a continuous ground copper pour for electrical and thermal performance.

Typical Applications
PIC32MX110F016DT-I/TL is suitable for 6 applications: Consumer Audio Accessories, Capacitive Touch User Interfaces, Low-Cost Graphical LCD Interfaces, USB Device Peripherals, Industrial Control Nodes, IoT Edge Sensor Hubs.
Consumer Audio Accessories
The PIC32MX110F016DT-I/TL's two I2S/SPI modules and MIPS32 M4K core suit low-cost audio accessories such as Bluetooth speaker docks, headphone amplifiers, and USB audio interfaces. With 40 MHz CPU bandwidth, the MCU can run MP3/AAC decode libraries in software while streaming I2S audio to an external DAC; the 4 KB SRAM is adequate for small audio buffers. Place the 44-VFTLA near the audio codec to keep I2S traces short, and route the dedicated USB PLL output to the on-chip USB peripheral if the accessory needs USB-C audio support. Power consumption below 0.5 mA/MHz at 40 MHz means roughly 20 mA active draw, easily sourced from a USB or Li-ion rail.
Recommended
Capacitive Touch User Interfaces
The PIC32MX110F016DT-I/TL integrates a Charge Time Measurement Unit (CTMU) that implements Microchip's mTouch capacitive touch sensing in hardware, eliminating the need for an external touch controller. Designers can scan up to 21 touch electrodes through the GPIO matrix, supporting buttons, sliders, and proximity sensors on appliances, industrial panels, and consumer gadgets. The 40 MHz MIPS core is more than sufficient to debounce, filter, and serialize touch events to a host MCU or LCD. Use the Peripheral Pin Select (PPS) feature to remap CTMU outputs to any GPIO, simplifying PCB layout. Pair with the 44-VFTLA exposed pad to maintain ground integrity for noise-immune touch performance.
Recommended
Low-Cost Graphical LCD Interfaces
The PIC32MX110F016DT-I/TL's Parallel Master Port (PMP) provides a parallel interface to drive small graphical LCDs (typically 128x64 to 320x240) without an external graphics controller. Designers can connect the PMP data/control pins directly to TFT or monochrome LCD modules, freeing the CPU to handle application logic at 40 MHz. The 4 KB SRAM and 16 KB Flash allow simple GUI rendering libraries and bitmap storage; for full-frame buffering step up to PIC32MX150F128D-I/TL with 32 KB SRAM. PPS allows flexible mapping of PMP signals to GPIO, simplifying routing on the compact 44-pin VFTLA footprint. Industrial temperature grade supports outdoor or factory-floor HMI panels.
Recommended
USB Device Peripherals
The PIC32MX110F016DT-I/TL's on-chip USB peripheral, paired with a dedicated PLL separate from the CPU PLL, enables full-speed USB device designs without external crystals. Common implementations include USB HID devices (keyboards, mice, custom controls), USB CDC virtual COM ports, and USB mass storage. The 16 KB Flash accommodates USB stacks such as Microchip's MLA or TinyUSB port; 4 KB SRAM is sufficient for CDC/HID endpoints. For designs requiring more code space, the same-footprint PIC32MX110F016CT-I/TL adds USB while preserving the layout. Use PPS to assign USB D+/D- to convenient GPIO positions on the 44-VFTLA package.
Recommended
Industrial Control Nodes
The PIC32MX110F016DT-I/TL operates across -40C to +105C and from 2.3 V to 3.6 V, satisfying industrial temperature and supply-rail requirements for sensor hubs, motor-control satellites, and PLC I/O modules. Two UARTs, two I2C, two SPI/I2S, and PPS give the designer flexible connectivity to sensors, driver ICs, and fieldbuses. The 40 MHz MIPS core can run simple PID loops or Modbus RTU slaves; 16 KB Flash is adequate for typical sensor-fusion code. The 44-VFTLA exposed pad provides mechanical stability and thermal dissipation in factory environments with high ambient temperatures.
Recommended
IoT Edge Sensor Hubs
The PIC32MX110F016DT-I/TL is well-suited for low-power IoT edge sensor hubs that aggregate I2C sensor data, perform local filtering, and forward results over UART or SPI to a higher-tier MCU or radio. Its sub-0.5 mA/MHz active current, multiple low-power modes, and small 6 mm x 6 mm 44-VFTLA footprint let it fit in coin-cell or energy-harvested designs. The CTMU can be repurposed for capacitance-based liquid level or proximity sensing alongside the main sensor stack. PPS allows the radio IRQ, I2C bus, and serial debug to share the 21 GPIOs without contention.

Key Differentiators
- Largest memory headroom in same 44-VFTLA package family (vs PIC32MX110F016CT-I/TL)
- Sub-0.5 mA/MHz active current consumption (vs PIC32MX110F016B-I/SS)
- Integrated mTouch CTMU peripheral (vs PIC32MX110F016D-I/PT)
Design Notes
The 44-pin VFTLA package has an exposed thermal pad on pin 44 that MUST be soldered to a continuous ground copper pour for both electrical performance and thermal dissipation. Estimated: with theta_JA around 30 C/W on a 4-layer JEDEC test board, dissipating 200 mW yields a junction temperature rise of 6C above ambient. For industrial designs near the +105C limit, provide at least 100 mm^2 of contiguous ground copper to keep junction temperature in spec.
Route PPS-remappable signals to convenient GPIO positions to minimize PCB layer changes. Place the 0.1 uF + 1 uF decoupling pair within 2 mm of each VDD pin (pins 1, 28), and add a bulk 10 uF tantalum or ceramic close to the highest-current VDD pin. Keep crystal traces short and surrounded by ground copper; for the USB peripheral, maintain 90-ohm differential impedance on D+/D-.
PPS registers are write-locked after reset; unlock them with CFGCON.IOLOCK=0 before remapping peripheral functions. Do not assume VDD=3.3 V always - the minimum 2.3 V rules out 1.8 V-only rails, but USB peripheral electrical specifications require 3.0-3.6 V. Avoid enabling CTMU and ADC simultaneously on shared analog pins without reviewing the pin assignment table; some functions are mutually exclusive on the same pad.
