PIC32MX110F016BT-V/SS Overview
What is a 32-bit microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory (Flash/SRAM), and a rich set of peripherals (UART, I2C, SPI, timers, ADC, PWM, etc.) into one package. 32-bit MCUs execute instructions over a wider data path than 8-bit or 16-bit MCUs, enabling higher computational throughput, larger addressable memory, and more efficient handling of complex algorithms. Within the Microchip taxonomy, the PIC32MX family sits at the low-power / cost-optimized end of the 32-bit PIC32 portfolio, bridging the gap between 16-bit PIC24/dsPIC devices and high-performance PIC32MZ parts.
Key features include two I2S/SPI modules for codec and serial communications, Peripheral Pin Select (PPS) for flexible pin mapping, a Parallel Master Port (PMP) for graphics interfaces, and a Charge Time Measurement Unit (CTMU) for mTouch capacitive touch sensing. The 40 MHz CPU with MIPS32 M4K core delivers less than 0.5 mA/MHz active current, and the part includes up to four DMA channels, two UART, and two I2C modules. The AEC-Q100 "V" suffix designates the automotive grade, making this part suitable for in-vehicle designs.
The PIC32MX110 architecture uses a 5-stage pipeline MIPS32 M4K core with single-cycle hardware multiply and divide, paired with separate PLLs for CPU and USB clocks. PPS allows digital peripheral I/O to be remapped to most general-purpose I/O pins, simplifying PCB layout. Multiple power-management modes (Run, Idle, Sleep) plus a configurable WDT with on-chip low-power RC oscillator support long battery-life or energy-harvesting applications.
Typical applications include automotive body electronics and HMI nodes, capacitive touch buttons and sliders via mTouch, USB audio peripherals, low-cost graphics interfaces through PMP, and general-purpose 32-bit embedded control. The wide peripheral mix and automotive qualification also make it suitable for industrial sensor hubs and consumer appliances requiring a 32-bit upgrade path from 16-bit PIC24 designs.
When designing with this MCU, reserve a clean 3.3V analog rail for the AVDD pin pair and place the decoupling capacitors within 3 mm of the supply pins. The PPS registers must be unlocked and configured before any remapped peripheral works correctly - failing to do this is one of the most common bring-up pitfalls for first-time PIC32 users.

Typical Applications
PIC32MX110F016BT-V/SS is suitable for 6 applications: Automotive Body Electronics, Capacitive Touch HMI (mTouch), USB Audio Peripherals, Low-Cost Graphics with PMP, Industrial Sensor Hubs, Battery-Powered IoT Edge Nodes.
Automotive Body Electronics
The PIC32MX110F016BT-V/SS fits automotive body modules such as door/window nodes, lighting controllers, and mirror actuators because of its AEC-Q100 V grade (-40C to +105C) and 40 MHz MIPS M4K core with 16 KB Flash. Its 2.3-3.6V supply tolerates 12V battery cold-crank and load-dump transients when paired with an external TVS and LDO. The two UART and two SPI/I2S channels can drive LIN-to-UART bridges, seat-control switch matrices, or LED matrix drivers while the CTMU enables capacitive touch entry panels.
Recommended
Capacitive Touch HMI (mTouch)
The PIC32MX110F016BT-V/SS is well suited for capacitive touch buttons, sliders, and proximity sensors thanks to its integrated Charge Time Measurement Unit (CTMU). CTMU hardware measures capacitance with sub-pF resolution in a single scan, freeing the M4K core from timed-charge software loops and lowering average power. Designers can map touch channels through Peripheral Pin Select (PPS) to any of the 21 I/O pins, simplifying PCB layout when sliders cross multiple board edges or wrap around enclosures.
Recommended
USB Audio Peripherals
The PIC32MX110F016BT-V/SS hosts a USB Full-Speed peripheral and dual I2S ports that pair nicely with low-cost audio codecs for USB speakers, headsets, and intercoms. Separate PLLs for CPU and USB allow the USB clock to track host SOF requests without disturbing the 40 MHz CPU core, which keeps audio streams sample-accurate. PPS reassigns I2S data and clock lines to convenient PCB routes, easing layout on small audio dongles where BGA packages are impractical.
Recommended
Low-Cost Graphics with PMP
The PIC32MX110F016BT-V/SS drives small parallel-port LCDs and OLEDs through its Parallel Master Port (PMP), enabling graphical user interfaces on appliances and instrument front panels. PMP can address up to 512 KB external memory and runs in 8-bit or 16-bit mode, so the 16 KB internal Flash is enough for UI asset compression plus code. Designers can leverage the 40 MHz M4K core for partial-screen refresh and simple animations without an external graphics controller.
Recommended
Industrial Sensor Hubs
The PIC32MX110F016BT-V/SS serves as an industrial sensor hub aggregating UART sensors, I2C peripherals, and SPI ADCs into a single Modbus RTU or CANopen node. Multiple DMA channels can offload the M4K core from continuous sensor reads, and the configurable Watchdog Timer with on-chip low-power RC keeps the node self-recovering if firmware hangs in noisy plant environments. AEC-Q100 V grade gives extra margin against the -40C to +105C industrial ambient required by many process-control cabinets.
Recommended
Battery-Powered IoT Edge Nodes
The PIC32MX110F016BT-V/SS supports battery-powered IoT edge nodes because of its sub-0.5 mA/MHz active core current, multiple Sleep and Idle power modes, and configurable WDT with on-chip low-power RC. The 40 MHz M4K core with hardware multiply can run lightweight TLS or LoRaWAN stacks from the 16 KB Flash, while PPS allows a single I/O pin to be reassigned between I2C sensor, SPI flash, and UART debug without rewiring the PCB. V grade AEC-Q100 also covers outdoor or in-vehicle IoT deployments.

Key Differentiators
- AEC-Q100 automotive grade with full USB peripheral (vs PIC32MX110F016BT-I/SS)
- On-chip CTMU for hardware capacitive touch (vs Generic PIC24 16-bit MCU at same price tier)
- 28-SSOP package option for hand-solderable prototypes (vs PIC32MX110F016BT-V/ML (28-QFN))
Design Notes
Estimated: at 40 MHz core clock and 3.3V supply with all peripherals enabled, the PIC32MX110F016BT-V/SS draws roughly 20 mA active (less than 0.5 mA/MHz core current from the datasheet). Add a 10 uF bulk plus a 0.1 uF decoupling cap within 3 mm of each VDD pin, and tie AVDD to VDD through a ferrite bead or shared rail filtered by 10 ohm + 10 uF. Under 12V automotive cold-crank the LDO headroom must hold VDD above 2.3V for the entire transient window.
Place the 28-SSOP decoupling capacitors on the same side as the MCU, with the smallest ceramic (0.1 uF) directly across pin 8/19 (VSS) and pin 28 (VDD). Keep the USB D+/D- differential pair matched within 2 mm and route VBUS through a 10 kohm pulldown to enable device-mode detection. The PPS feature lets you move UART, I2C, and SPI onto any convenient I/O pin, so reserve alternate pads for bring-up rework when laying out the breakout.
The most common PIC32MX bring-up mistake is forgetting to unlock the Peripheral Pin Select (PPS) registers - peripherals will appear dead on the wrong pins until IOLOCK is cleared and PPS assignments are remapped. Also confirm the JTAG/MSCAN pin enable fuses match the debugger being used (PGEDx/PGECx on the 4-wire ICSP pins 4/5). For USB designs, attach a 1.5 kohm pull-up to D+ only after the firmware enables the USB pull-up bit; a permanently-attached pull-up prevents enumeration on some hosts.
