PIC32MX110F016D-I/PT Visão geral
What is a PIC32MX microcontroller? The PIC32MX family is Microchip's line of 32-bit MIPS-based microcontrollers, sitting in the taxonomy: microcontroller -> embedded MCU -> 32-bit MCU -> MIPS M4K core. PIC32MX parts combine the legacy PIC peripheral set with the wider 32-bit MIPS datapath, providing integer performance up to ~52 DMIPS at 40 MHz while keeping code-density benefits of the MIPS instruction set.
Key features include Peripheral Pin Select (PPS) for flexible signal routing, a Parallel Master Port (PMP) for graphics or external memory interfaces, a Charge Time Measurement Unit (CTMU) for mTouch capacitive touch buttons and sliders, brown-out reset, power-on reset, and five 16-bit timers. The integrated 10-bit ADC, multiple UART/I2C/SPI peripherals, and USB-ready companion peripherals allow this device to replace external logic in cost-sensitive nodes.
From an architectural standpoint, the PIC32MX110F016D uses a Harvard-style MIPS32 M4K core with separate Flash and SRAM buses, supporting 16 KB Flash for code and 4 KB SRAM for data. Its DMA controller offloads I/O from the CPU, and the CTMU provides a precise time-measurement current source for touch sensing without external analog components.
Typical applications include low-cost USB device nodes, capacitive touch user interfaces, small graphics LCDs driven by PMP, industrial sensor conditioning nodes, and consumer appliances needing 32-bit headroom at 8-bit prices. The industrial temperature grade (-40 C to +85 C) suits outdoor enclosures and factory-floor deployments.
When designing with this part, ensure the 2.3 V to 3.6 V supply is decoupled with 100 nF plus 10 uF bulk capacitors close to the VDD pins, and use PPS to remap peripherals when the PCB layout forces non-standard pin assignments. For migration, the same die is offered in 44-QFN (PIC32MX110F016D-V/ML) for space-constrained boards.

Aplicações típicas
PIC32MX110F016D-I/PT é adequado para 6 aplicaçãos: Low-Cost USB Device Node, Capacitive Touch User Interface (mTouch), Small Graphics LCD via PMP, Industrial Sensor Conditioning Node, Consumer Appliance Controller, Educational / Maker Platform MCU.
Low-Cost USB Device Node
The PIC32MX110F016D-I/PT suits low-cost USB device nodes because its 40 MHz MIPS32 M4K core delivers sufficient throughput for HID, CDC, or vendor-class USB endpoints, while 16 KB Flash and 4 KB SRAM cover typical USB stacks. The 44-pin TQFP exposes the USB D+/D- pins and the on-chip 10-bit ADC, letting the MCU replace a USB-serial bridge plus external MCU in cost-sensitive peripherals. The 2.3 V to 3.6 V supply aligns directly with USB 3.3 V rails.
Recomendado
Capacitive Touch User Interface (mTouch)
The integrated Charge Time Measurement Unit (CTMU) makes the PIC32MX110F016D-I/PT a fit for mTouch capacitive buttons and sliders. The CTMU supplies a constant current whose charge time encodes capacitance, measured by Timer1, allowing 8 to 12 touch channels without external analog components. Combined with PPS, the touch channels can be routed to any spare I/O pin, simplifying PCB layout. The industrial temperature grade supports kitchen and appliance environments.
Recomendado
Small Graphics LCD via PMP
The Parallel Master Port (PMP) of PIC32MX110F016D-I/PT can drive small QVGA or WQVGA graphics TFTs directly without an external controller. The 21 available I/O pins provide the data, address, and control signals needed for 8-bit PMP, and DMA offloads pixel streaming from the CPU. With 4 KB SRAM, the part supports modest framebuffer partitioning for menus, gauges, or status icons. Designers targeting larger panels should upgrade to PIC32MX150F128B for more SRAM.
Recomendado
Industrial Sensor Conditioning Node
The PIC32MX110F016D-I/PT works as an industrial sensor conditioning node because its 10-bit ADC, multiple UART/I2C/SPI peripherals, and -40 C to +85 C industrial grade suit factory-floor environments. Two I2S/SPI modules allow simultaneous connection to a sensor front-end and a host PLC. The 0.5 mA/MHz dynamic current keeps total node consumption low for line-powered 4 mA to 20 mA loops. CTMU also supports simple temperature or humidity capacitance sensing.
Recomendado
Consumer Appliance Controller
The PIC32MX110F016D-I/PT suits consumer appliances such as coffee machines, washing machines, or smart kitchen devices, where 16 KB Flash holds the control loop and UI logic. Its CTMU drives touch panels, its PMP drives small status displays, and its multiple timers handle motor PWM. The 2.3 V to 3.6 V rail allows direct battery or 3.3 V regulator operation. Industrial temperature grade ensures reliability near heat sources.
Recomendado
Educational / Maker Platform MCU
The PIC32MX110F016D-I/PT serves as an educational 32-bit MCU thanks to its low cost, Microchip's free MPLAB X IDE, and the active PIC32 community. The 44-pin TQFP is breadboard-friendly with carrier boards, while PPS lets students experiment with peripheral remapping. Compared to 8-bit PIC16 parts, the 32-bit MIPS core offers a step up in DMIPS while staying within hobbyist budgets. Hobbyists targeting USB or graphics can scale to PIC32MX150F128B without changing the footprint.

Principais diferenciais
- Lowest unit cost within the 44-TQFP PIC32MX family (vs PIC32MX150F128B-I/PT)
- CTMU mTouch hardware integrated on-die (vs PIC32MM0064GPM048T-I/M4)

Notas de projeto
Decouple the PIC32MX110F016D-I/PT with 100 nF plus 10 uF ceramic bulk placed within 5 mm of each VDD pin (pins 20 and 42). The internal regulator requires this low-impedance path to remain stable across load transients when CTMU or PMP drives high-current edges. For battery-powered designs, use a separate LDO such as MCP1700 to isolate the MCU from switching noise on the main rail.
Route the 40 MHz crystal traces on the TQFP package as short and symmetric as possible, with the load capacitors placed within 3 mm of OSC1 and OSC2 (pins 43 and 44). Use a ground guard ring around the crystal area to reduce EMI coupling. Keep high-speed digital signals away from the analog AVSS/AVDD pair to preserve ADC accuracy.
Do not confuse the I/PT (industrial -40 C to +85 C, 44-TQFP) variant with the V/PT (industrial -40 C to +105 C, same TQFP) or V/ML (-40 C to +105 C, 44-QFN). All three share the same die but differ in package or temperature grade. Verify pin 1 orientation carefully because TQFP pin numbering differs from QFN even when the die is identical.
When driving capacitive touch channels via CTMU, place a ground fill beneath the touch pads and route the touch signals with short, parallel traces. Avoid running touch traces under the MCU switching power section, since high dV/dt coupling can inject false CTMU counts. Calibration of CTMU current source at production is recommended to compensate for process and temperature variation.
