PIC32MX110F016B-V/SS Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), data memory (SRAM), and integrated peripherals such as timers, communication controllers, and analog blocks. The PIC32MX1XX/2XX family belongs to the broader taxonomy: microcontroller -> embedded processor -> semiconductor IC. Within Microchip's portfolio, the PIC32MX sits between the 16-bit PIC24F/G and the higher-end PIC32MZ families, balancing MIPS performance, low power, and rich peripheral integration for cost-sensitive designs.
Key differentiating features include Peripheral Pin Select (PPS), which remaps most digital peripherals to any compatible I/O pin - dramatically simplifying PCB layout and reducing pin conflicts. The integrated CTMU enables capacitive touch measurement via a single ADC channel and timing source, supporting mTouch buttons, sliders, and proximity sensing without an external touch controller. The PMP interface supports graphics LCDs, and the dual I2S/SPI blocks support audio codecs and full-duplex serial communications.
Architecturally, the PIC32MX110F016B-V/SS uses the MIPS32 M4K core with a 5-stage pipeline, hardware multiply/divide, and tightly-coupled SRAM for deterministic interrupt response. The Flash program memory supports self-programming via the boot Flash region, and the device includes an on-chip debugger accessible through the ICSP interface using MPLAB Snap, MPLAB ICD-4, or PICkit 4.
Typical applications include consumer audio peripherals, low-cost HMI panels, capacitive-touch human-interface devices, USB HID peripherals, industrial sensor hubs, and low-power IoT edge nodes. The wide operating temperature range (-40C to +105C) and 2.3V-3.6V supply suit battery and industrial 3.3V bus systems. The PIC32MX110F016B-V/SS offers compelling price-to-performance compared with 8/16-bit MCUs for designs requiring MIPS-class throughput without the cost of higher-tier PIC32MZ parts.
Design tip: place a 0.1 uF decoupling capacitor as close as possible to every VDD/VSS pair, and connect the MCLR pin through a 10 kohm pull-up to VDD for proper reset behavior. Use PPS to assign peripherals to convenient pins during schematic capture, and configure the CTMU via the dedicated CTMUCON register set for accurate touch measurements.

Typical Applications
PIC32MX110F016B-V/SS is suitable for 6 applications: Consumer Audio Peripheral Controller, Capacitive Touch Human-Machine Interface, Industrial Sensor Hub and Modbus Node, USB HID Peripheral Device, Battery-Powered IoT Edge Node, Low-Cost Graphical LCD HMI Panel.
Consumer Audio Peripheral Controller
The PIC32MX110F016B-V/SS suits low-cost consumer audio accessories such as Bluetooth headphone controllers, USB speakers, and microphone arrays. Its dual I2S/SPI modules directly interface to codecs like the SGTL5000 and CS43L22, while the 40 MHz MIPS M4K core runs lightweight audio mixing and DSP routines. The 16 KB Flash holds application code, USB HID stacks, and volume-control state machines. Unlike higher-tier MCUs, this part keeps BOM cost low while delivering deterministic interrupt latency for sample-rate-accurate audio I/O. Total active current is under 20 mA, suiting battery-powered headphones.
Recommended
Capacitive Touch Human-Machine Interface
The integrated CTMU enables the PIC32MX110F016B-V/SS to implement mTouch capacitive buttons, sliders, and proximity sensors without an external touch controller. Designers connect sensor pads directly to ADC-capable pins and use the CTMU charge-time measurement principle with the 10-bit ADC for sub-percent touch detection. The 16 KB Flash hosts the mTouch library and gesture processing, while PPS remaps peripherals to convenient PCB locations. Compared with dedicated touch ICs, this approach reduces BOM count and allows touch firmware updates through ICSP. Ideal for appliance panels and small HMI boards.
Recommended
Industrial Sensor Hub and Modbus Node
The PIC32MX110F016B-V/SS acts as a multi-sensor aggregation node on industrial 3.3V backplanes, reading temperature, pressure, and flow sensors over I2C/SPI and exposing data via UART-based Modbus RTU. The wide -40C to +105C temperature rating supports cabinet-mounted installations, and the 2.3V-3.6V supply accepts standard 3.3V industrial rails. PPS allows flexible pin assignment to isolate analog sensor traces from switching lines. With 4 KB SRAM the MCU can buffer 1-second data from up to 8 sensors for store-and-forward over Modbus. AEC-Q100 qualification is planned for V-grade.
Recommended
USB HID Peripheral Device
Use the PIC32MX110F016B-V/SS as the host MCU for low-speed USB HID peripherals such as custom keyboards, mice, or barcode scanners. While this specific variant lacks the on-chip USB module, the pin-compatible PIC32MX210F016B upgrade path provides USB OTG without any PCB change. Designers can prototype with PIC32MX110 and migrate to PIC32MX210 for production. The 16 KB Flash fits HID class drivers and keymaps, and the 40 MHz MIPS M4K core handles USB polling and HID report generation with margin. MPLAB X HID stack is freely available from Microchip.
Recommended
Battery-Powered IoT Edge Node
For low-duty-cycle IoT edge nodes such as environmental monitors and asset trackers, the PIC32MX110F016B-V/SS offers sleep currents down to microamp levels when the CPU is halted and peripherals gated. Designers wake the MCU periodically to read sensors, transmit via UART/SPI-connected radios like the RN2483 LoRa module, and return to sleep. The 2.3V-3.6V supply accepts single-cell Li-Ion or 2x AA chemistries directly. With 4 KB SRAM, the MCU buffers sensor bursts before transmission, and the wide -40C to +105C range supports outdoor enclosures.
Recommended
Low-Cost Graphical LCD HMI Panel
The PMP (Parallel Master Port) on the PIC32MX110F016B-V/SS drives small graphical LCDs and OLED panels up to QVGA resolution without external display controller ICs. Designers connect 8-bit data plus 4 control lines to the LCD and use the 16 KB Flash for frame buffer manipulation and on-screen menus. The 40 MHz MIPS core comfortably refreshes QVGA at 30 Hz when written in optimized XC32. Compared with discrete display controllers, the integrated PMP approach reduces BOM cost by 50-70% for cost-sensitive appliances and instrument front panels.

Key Differentiators
- Peripheral Pin Select (PPS) for flexible routing (vs PIC32MX110F016B-I/SS)
- On-chip CTMU for mTouch capacitive sensing (vs PIC32MX210F016B-I/SS)
- MIPS32 M4K 32-bit core at lower cost than PIC32MZ (vs PIC32MZ variants)
Design Notes
Estimated: at 40 MHz with all peripherals active, core current draw is approximately 20 mA from the 3.3V VDD rail. Place a 0.1 uF decoupling capacitor within 5 mm of every VDD/VSS pin pair, and add a bulk 10 uF tantalum or ceramic capacitor near the MCU for transient load support. The PIC32MX110F016B-V/SS supports internal core voltage regulation; no external regulator is required for the core, but the VDD pins must be held above 2.3V for proper Flash read operations.
Route the ICSP signals PGED1/PGEC1 (or PGED2/PGEC2) directly to a programming header with traces under 100 mm and guarded by GND to avoid crosstalk. Use PPS to remap peripheral functions to pins physically distant from analog signals, isolating noise-sensitive traces from PWM and switching lines. Keep the MCLR trace short with a 10 kohm pull-up to VDD; long MCLR traces can pick up noise and cause spurious resets.
Do not leave the MCLR pin floating - it must be tied to VDD through a pull-up resistor (typically 10 kohm) to avoid unintended resets. The 28-SSOP package has a thermal pad area below the body that must be soldered to the PCB pad to meet rated thermal performance. When migrating from PIC32MX110F016B-V/SP (PDIP) to /SS (SSOP), confirm your PCB layout matches the SSOP-28 footprint - the SSOP body is narrower and the pin pitch is 0.65 mm versus 2.54 mm on PDIP.
