PIC32MX110F016CT-I/TL Overview
What is a 32-bit microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory (Flash and RAM), and peripherals (UART, I2C, SPI, ADC, timers) into one package. The PIC32MX family sits in the hierarchy: microcontroller -> 32-bit MCU -> MIPS-based MCU -> PIC32MX family -> PIC32MX1xx sub-family. It targets cost-sensitive applications where 8-bit MCUs run out of headroom but full application processors are overkill, bridging the gap between Microchip's PIC16/PIC24 lines and higher-end PIC32MZ devices.
Key features include 16KB of Flash with self-programming support, 4KB of SRAM, a 10-bit 1 Msps ADC with up to 13 channels, two UART, two I2C, and two SPI modules, plus five 16-bit timers/counters. The peripheral pin select (PPS) feature allows flexible remapping of digital peripherals to any I/O pin, simplifying PCB routing. The device operates from 2.3V to 3.6V and supports industrial temperature ranges of -40C to +85C.
Architecturally, the MIPS32 M4K core delivers 1.56 DMIPS/MHz with single-cycle multiply and hardware divide, supported by a 5-stage pipeline. The integrated DMA controller with up to four channels offloads data movement between peripherals and memory, freeing the CPU for application code. Separate PLLs handle CPU and USB clocking, enabling flexible system timing.
Typical applications include low-cost IoT sensor nodes, USB device peripherals, consumer appliances, industrial control interfaces, and human-machine interface (HMI) touch panels. The combination of small package, USB 2.0 full-speed support, and rich peripherals makes the PIC32MX110F016C family a versatile entry point for embedded designs.
When designing with this MCU, ensure the exposed thermal pad is properly soldered to a sufficient copper pour to meet thermal specifications. Use MPLAB X IDE with XC32 compiler for development, and consider the PIC32MX1xx/2xx family datasheet and the family reference manual for peripheral programming details.

IoT Sensor Node with Serial Connectivity
For low-cost IoT sensor nodes, the PIC32MX110F016CT-I/TL provides UART, I2C, and SPI interfaces to connect environmental sensors, then forwards readings via Modbus RTU, LIN bus, or a serial-to-Ethernet bridge. Its 13-channel 10-bit ADC reads analog sensors directly, while the 4KB RAM buffers time-series data before transmission. Operating at 2.3V to 3.6V, it works with 3.3V sensor rails and coin-cell or Li-ion battery stacks. Low-power sleep modes extend battery life in field deployments.

Industrial Control Interface Panel
Industrial HMI panels and control interfaces benefit from the PIC32MX110F016CT-I/TL's peripheral mix and industrial temperature range. Its 25 I/O pins interface to keypads, rotary encoders, LED indicators, and segment displays, while two UART channels handle RS-485 or RS-232 communication to PLCs or motor drives. The DMA controller offloads repetitive I/O servicing, freeing the CPU for user-interface logic. The -40C to +85C industrial range supports factory floor and outdoor cabinet installations.
Recommended
Consumer Appliance Controller
Small kitchen and household appliances such as coffee machines, blenders, and air purifiers use the PIC32MX110F016CT-I/TL as a main controller. Its combination of UART/I2C/SPI interfaces drives motor control ICs, temperature sensors, and display panels. The 10-bit ADC reads thermistor inputs for closed-loop temperature control, while PWM timers drive TRIAC or MOSFET-based heating elements. At roughly $1.84 per unit in volume, it delivers 32-bit performance at 8-bit cost, enabling feature-rich appliances.
Recommended
Portable Data Logger
Battery-powered data loggers for environmental monitoring, asset tracking, and field instrumentation leverage the PIC32MX110F016CT-I/TL's low-power modes and DMA-driven peripheral handling. The 4KB SRAM buffers logged samples, while the 16KB Flash stores both firmware and a small configuration log. SD card interfaces via SPI extend storage to gigabytes, and the ADC captures analog inputs at up to 1 Msps for high-speed transients. USB device mode enables convenient data download to a host PC.
Recommended
Educational and Hobby Development Platform
The PIC32MX110F016CT-I/TL and its derivatives power Microchip's Curiosity Development Board and Digilent chipKIT platforms, making it ideal for hobbyists and university curricula. MPLAB X IDE with the free XC32 compiler and Microchip's Harmony framework provides a complete software ecosystem. The MIPS M4K core teaches RISC concepts, while USB, I2C, SPI, and ADC peripherals demonstrate embedded protocols. Lower-cost PIC32 variants let students build complete projects on a tight budget.
Recommended
LED Lighting Controller
Addressable LED strip controllers for architectural and entertainment lighting use the PIC32MX110F016CT-I/TL as a USB-connected DMX or Art-Net bridge. Two UART channels accept DMX512 input, while a high-speed SPI drives APA102 or WS2812 LED strips with deterministic timing. The DMA controller handles LED data streaming without CPU intervention, freeing cycles for user-interface and protocol processing. The 40MHz core easily sustains multi-thousand-pixel refresh rates for smooth animations.

Key Differentiators
- Lowest-cost entry point into 32-bit USB microcontrollers (vs PIC32MX120F032C-I/TL)

- Versatile packaging options for prototype vs production (vs PIC32MX110F016B-V/SP)
Design Notes
The PIC32MX110F016CT-I/TL requires a clean 3.3V supply within 2.3V to 3.6V. Place a 100nF ceramic decoupling capacitor as close as possible to each VDD pin, plus a bulk 10uF tantalum or ceramic capacitor on the main supply rail. For USB applications, the internal voltage regulator provides 3.3V from the USB VBUS line, but an external LDO is recommended for self-powered designs to ensure clean rail during USB suspend events.
The VTLA-36 package's exposed thermal pad must be soldered directly to a ground copper pour with multiple thermal vias to a PCB inner ground plane. Without proper thermal dissipation, junction temperature may exceed the 85C industrial limit in enclosed housings. Minimum recommended copper area is 1 square inch of 2 oz copper, with at least 9 thermal vias (0.3 mm drill) connecting to the inner ground plane for high-current designs.
Route the 40MHz system traces with controlled impedance if connecting to external memories or high-speed peripherals. Keep the USB D+ and D- traces as a 90-ohm differential pair with matching length, and place the USB connector within 25 mm of the MCU pins. Use a 4-layer PCB stackup with dedicated ground and power planes for best EMI performance; isolate analog reference voltages (Vref+, Vref-) from digital switching traces.
Take advantage of the Peripheral Pin Select (PPS) feature to remap UART, SPI, I2C, and timer peripherals to any available digital I/O pin, simplifying PCB routing. Reserve pins RB6 and RB7 for ICD (in-circuit debugger) connections during prototype bring-up so that the PICkit 4 or ICD 4 can program and debug the board without rework. Decouple the Vref+ pin with 10nF and 1uF capacitors if the ADC is used for precision measurements.
Avoid programming the configuration bits to disable the JTAG or ICD interface unintentionally, as this can lock out the device and require high-voltage programming to recover. Always configure the watchdog timer (WDT) during development to prevent runaway code from hanging the system. When migrating between PIC32MX1xx variants, verify the pinout compatibility, as some pins change function between package options and memory sizes.
