PIC32MX110F016C-I/TL Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and a rich set of peripherals. The PIC32MX110 family belongs to the broader 32-bit MCU category, which sits above 8-bit and 16-bit MCUs in performance and addresses the same role as ARM Cortex-M0/M3 parts. Within Microchip's portfolio, the 32-bit MIPS-based PIC32 line competes with the dsPIC and PIC24 16-bit lines as well as Microchip's own ARM-based SAM family.
Key features include 16 KB (16K x 8) Flash, 4 KB SRAM, hardware DMA (up to 4 channels), configurable Watchdog Timer with on-chip Low-Power RC oscillator, multiple power-management (Sleep/Idle) modes, and JTAG/ICSP debug. PPS remaps digital peripherals to almost any I/O pin, easing PCB layout for dense designs.
The device is built around a MIPS32 M4K Harvard core with single-cycle hardware multiply and a 5-stage pipeline. The 40 MHz core delivers approximately 50 DMIPS, and the bus matrix connects the core, DMA engine, and peripherals without stalling the CPU. The 36-VTLA package uses an exposed pad for thermal relief.
Typical applications include consumer and industrial embedded control, USB-less PIC32 designs, sensor hubs, low-cost graphical user interfaces (with PMP to TFT/segment LCD), and educational or hobby platforms. The 16 KB Flash / 4 KB SRAM balance fits small TCP/IP or USB stacks running on a sister PIC32 part.
When designing, allocate Flash budget carefully - 16 KB accommodates roughly 12 KB of code after the bootloader, leaving limited room for field-upgrade images. Plan ICSP pins early: any PGECx/PGEDx pair is valid for debug and programming, but only as a matched pair.

Typical Applications
PIC32MX110F016C-I/TL is suitable for 6 applications: Industrial Sensor Hub, Consumer Device Controller, Educational / Hobby Development Platform, USB-less PIC32 Embedded Module, Display Interface (PMP to Segment LCD), Low-Cost Data Logger.
Industrial Sensor Hub
The PIC32MX110F016C-I/TL fits industrial sensor hubs because its 32-bit MIPS32 M4K core at 40 MHz can run a small RTOS while driving two SPI buses, two I2C buses, and a UART for sensor fusion. The 16 KB Flash accommodates a FreeRTOS binary plus modest sensor-processing code; the 4 KB SRAM holds sample buffers between DMA transfers. Peripheral Pin Select (PPS) lets designers place each peripheral on the most convenient I/O pin, simplifying the PCB layout when many sensors fan out from a single hub. Compared with 8-bit MCUs, the '110 delivers cleaner floating-point throughput for low-pass filtering of accelerometer/gyro data without external DSP.
Recommended
Consumer Device Controller
For consumer device controllers (appliance UI, e-meter, smart thermostat), the PIC32MX110F016C-I/TL delivers enough compute for a button-driven menu and a segmented LCD via the PMP peripheral. At 40 MHz the M4K core handles UI refresh and ADC sampling in parallel using the 4-channel DMA engine. The 2.5-3.6 V supply range aligns directly with 3.3 V coin-cell or USB-derived rails, simplifying the analog front end. Industrial -40C to +85C qualification supports deployment in unheated enclosures and garages without concern for cold-start failures.
Recommended
Educational / Hobby Development Platform
Hobbyists and universities value the PIC32MX110F016C-I/TL because it brings a real 32-bit MIPS core at an 8/16-bit price point, supported by the free MPLAB X IDE and XC32 compiler. The 36-VTLA footprint is breadboard-friendly via a breakout PCB, and the ICSP interface works with the low-cost MPLAB Snap or PICkit 4. The 16 KB Flash easily hosts Microchip's Harmony or a student RTOS example, while 4 KB SRAM fits modest TCP/IP-light stacks. The exposed pad aids thermal dissipation during sustained JTAG debug sessions.
Recommended
USB-less PIC32 Embedded Module
Where a system already provides an external USB-to-UART bridge (FTDI or native hub), the PIC32MX110F016C-I/TL functions as a low-cost compute core. Its DMA engine and PPS flexibility let it handle multiple serial buses without CPU intervention, freeing the M4K core for application logic. The 5x5 mm VTLA footprint packs 25+ GPIO into a small area, enabling compact module designs that drop into larger carrier boards. Designers gain the rich PIC32 ecosystem at the lowest tier of memory size.
Recommended
Display Interface (PMP to Segment LCD)
The PIC32MX110F016C-I/TL's Parallel Master Port (PMP) peripheral directly drives character LCDs and small segment LCDs without an external controller, lowering BOM cost. At 40 MHz, the M4K core refreshes a 4x20 character display in microseconds, leaving ample CPU budget for application logic. The 16 KB Flash comfortably fits Microchip's PMP driver stack and a custom character set, while 4 KB SRAM holds screen buffers. Peripheral Pin Select enables flexible PMP data-line assignment, easing routing on the 36-VTLA package.
Recommended
Low-Cost Data Logger
The PIC32MX110F016C-I/TL is well suited to compact data loggers that sample sensors via ADC or SPI and store bursts to external EEPROM or SD cards. The 4-channel DMA engine offloads sample-to-memory transfers without CPU intervention, and PPS allows flexible pin assignment for SD card SPI mode. Industrial -40C to +85C temperature range supports outdoor logger deployments. The 4 KB SRAM fits multi-sample ring buffers; the 16 KB Flash holds the logger firmware plus a small FAT driver for SD card compatibility.

Key Differentiators
- Lowest cost entry point to PIC32 ecosystem (vs PIC32MX130F064C-I/PT)
- Tube packaging for low-volume / prototype builds (vs PIC32MX110F016C-I/PT)
- Identical pinout to PIC32MX130 family for drop-in upgrades (vs PIC24HJ64GP502-I/SP)
Design Notes
PIC32MX1xx MCUs require a clean 3.3 V rail; place a 10 uF tantalum or ceramic bulk capacitor plus a 0.1 uF ceramic decoupling cap within 5 mm of every VDD/VSS pin pair. The on-chip voltage regulator sources internal 1.8 V from VDD; heavy load steps on the internal regulator can cause brown-outs without adequate bulk capacitance. The 36-VTLA has multiple VDD/VSS pairs (pins 8, 14, 19, 32 for VDD and pins 5, 11, 20, 31 for VSS) - all must be connected for noise immunity.
The 36-VTLA package has an exposed thermal pad that must be soldered to a grounded copper pour (minimum 1 square inch) for thermal relief and electrical grounding. Without proper pad soldering, junction temperatures can rise 30-40 C above rated limits under sustained DMA activity. Use microvia-in-pad if the design requires via-in-pad for ground plane continuity beneath the package.
PIC32MX110F016C has multiple PGECx/PGEDx pin pairs (PGEC1/PGED1 and PGEC2/PGED2). ICSP requires a matched pair - you cannot use PGEC2 with PGED1. According to Microchip debug documentation, mixing pairs prevents programming and debug connection. Reserve both pairs in your schematic to give board variants flexibility, but only use one pair at a time. Also note that PPS-mapped peripherals may conflict with reserved ICSP pins if not configured before debug.
Peripheral Pin Select (PPS) lets you remap digital peripherals to almost any digital I/O pin, but the analog-capable pins (AN0-AN15) have specific remapping rules. Place noise-sensitive analog traces (ADC inputs, reference voltages) away from switching digital lines and high-current traces. Group SPI and I2C peripherals together on adjacent pins when possible to minimize trace crossing.
