PIC32MX110F016B-I/SS 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripherals such as timers, ADC, and communication interfaces on one die. The PIC32MX1XX/2XX family belongs to the broader category of 32-bit microcontrollers -> RISC microcontrollers -> MIPS32-based MCUs -> embedded processors -> semiconductors. It is designed as an entry-level upgrade path for engineers migrating from PIC16/PIC24 devices who need higher throughput for USB, graphics, or audio front-end tasks.
Key features include a 10-bit ADC with up to 12 analog input channels, four hardware DMA channels, a Charge Time Measurement Unit (CTMU) for touch and capacitive sensing, two UART, two SPI, and two I2C peripherals, plus a Parallel Master Port (PMP) for graphics or external memory expansion. The 21 general-purpose I/O pins support Peripheral Pin Select (PPS), which allows digital peripheral signals to be remapped to a wide range of physical pins, simplifying PCB layout. The device operates from 2.3 V to 3.6 V with industrial -40C to +85C temperature range.
Internally the PIC32MX110F016B uses the MIPS32 M4K core with single-cycle hardware multiply/divide, a 5-stage pipeline, and a separate PLL for the system clock. Five 16-bit timers/counters and a configurable watchdog with on-chip low-power RC oscillator provide robust task scheduling. The part supports ICSP (In-Circuit Serial Programming) and JTAG debugging through the MPLAB X IDE with the free XC32 compiler, enabling rapid firmware development.
Typical applications include USB HID devices, low-cost audio playback front-ends, capacitive touch user interfaces, sensor hubs, and small graphic LCD controllers. The combination of CTMU, DMA, and PMP makes it a fit for human-machine interface (HMI) panels and consumer appliances.
When designing with this MCU, allocate the 16 KB Flash budget carefully - the bootloader plus USB stack plus application code leaves only a few KB for user logic. Use the CTMU and DMA offload the CPU from touch scanning to keep MIPS available for application work. Pin 1 dot marker should be observed carefully for SSOP-28 land pattern.

일반적인 애플리케이션
PIC32MX110F016B-I/SS 적합 용도: 7 애플리케이션s: USB HID Peripheral Front-End, Capacitive Touch User Interface, Low-Cost Audio Playback Front-End, Sensor Hub and Data Logger, Small Graphic LCD Controller, Home Appliance Control Board, Industrial Sensor Conditioning Node.
USB HID Peripheral Front-End
The PIC32MX110F016B-I/SS fits USB HID-class peripherals when paired with an external USB transceiver, leveraging its 40 MHz MIPS M4K core to handle HID report parsing within tight USB frame timing. The 10-bit ADC with 12 channels reads analog controls (potentiometers, sliders) at up to 1 Msps aggregate, while four DMA channels offload buffer movement to free CPU bandwidth. With 4 KB SRAM, designers must keep HID descriptors compact, and the two UART peripherals support debug logging over CDC bridge.
추천
Capacitive Touch User Interface
The CTMU (Charge Time Measurement Unit) integrated in the PIC32MX110F016B-I/SS provides hardware-based touch scanning without an external touch controller, enabling cost-sensitive HMI panels in appliances and consumer devices. Combined with the 4 DMA channels and 10-bit ADC, the MCU can scan 12+ touch electrodes in microseconds while leaving CPU bandwidth for backlight control and user feedback. The 16 KB Flash budget accommodates MPLAB Harmony touch libraries and basic UI state machines.
추천
Low-Cost Audio Playback Front-End
The PIC32MX110F016B-I/SS supports I2S/AC97 digital audio via its two SPI peripherals operating in framed mode, enabling playback from SD card or serial Flash to an external DAC at 44.1/48 kHz sample rates. The 5-stage pipeline and single-cycle multiply handle 16-bit PCM decode without DSP acceleration, while PMP (Parallel Master Port) can drive character LCDs or small OLED displays for visualization. The 4 KB SRAM constrains buffer size, so design typically uses double-buffered sectors rather than full-file RAM cache.
추천
Sensor Hub and Data Logger
The PIC32MX110F016B-I/SS serves as a low-power sensor hub with two I2C and two SPI ports for multi-sensor fan-out, leveraging DMA to autonomously sample and store readings without CPU wakeup. The 10-bit ADC provides auxiliary analog channels for battery monitoring or thermistor measurement, while the CTMU enables pulse-based flow or optical sensing. Industrial -40C to +85C operation supports outdoor or factory-floor installations, and the 4 KB SRAM is adequate for circular buffering before periodic SD writes.
추천
Small Graphic LCD Controller
Using the PMP (Parallel Master Port), the PIC32MX110F016B-I/SS can directly drive small 128x64 monochrome OLED or character LCD panels without an external framebuffer controller, ideal for compact HMI in industrial control panels. The 40 MHz core sustains 2-frame-per-second updates for 128x64 bitmaps from on-chip Flash, while the 10-bit ADC reads user potentiometers for contrast or backlight PWM control. The 4 KB SRAM holds one framebuffer line at a time; designers update row-by-row in tight inner loops.
추천
Home Appliance Control Board
The PIC32MX110F016B-I/SS fits white-goods control boards - washing machines, dishwashers, microwave ovens - where cost and reliability dominate the BOM decision. Its 21 GPIO pins drive relays, triacs, and LED indicators, while the 10-bit ADC reads NTC temperature sensors and motor current sense. The CTMU detects water level or capacitive user-panel buttons, and the 5 general-purpose timers generate PWM for motor speed control. With industrial temperature grade and a robust MIPS32 pipeline, it is qualified for 10+ year service life.
추천
Industrial Sensor Conditioning Node
Industrial 4-20 mA or 0-10 V sensor signal conditioning benefits from the PIC32MX110F016B-I/SS's 10-bit ADC and its DSP-style instructions for digital filtering. The two UART peripherals bridge to RS-485 transceivers for Modbus RTU communication, while the SPI ports connect to external 16/24-bit ADCs for precision measurement channels. With -40C to +85C operation and 2.3-3.6 V input, the MCU is well-suited to factory-floor DIN-rail sensor modules where stable operation across thermal cycling is essential.

주요 차별점
- Smallest Flash option in 28-SSOP PIC32MX1XX family (vs PIC32MX130F064B-I/SS)
- Identical peripheral set across the family (vs PIC32MX150F128B-I/SS)

설계 노트
The PIC32MX110F016B-I/SS has three VDD pins (8, 19 area, 28) and three VSS pins (5, 15, 19) on the 28-SSOP package. Place a 0.1 uF ceramic decoupling capacitor within 3 mm of each VDD/VSS pair, plus a single 10 uF bulk capacitor on the main supply rail. The AVDD pin must be tied to VDD; if ADC noise is a concern, add a ferrite bead between VDD and AVDD and decouple AVDD locally with 10 uF + 0.1 uF.
Peripheral Pin Select (PPS) remaps digital peripherals to RPn pins, but analog functions (ADC, VREF, CTMU) are fixed to dedicated pins. When laying out the PCB, route analog traces first - place AN0-AN11 adjacent to the MCU - and let PPS handle the digital UART/SPI/I2C remapping after that. Pin 1 dot marker orientation matters: SSOP-28 pin numbering is counter-clockwise from the dot, and the part should be installed with pin 1 at the top-left of the silkscreen.
Estimated: the 16 KB Flash is consumed quickly by the Harmony framework or USB stack - reserve at least 8 KB for application code when planning firmware. The CTMU requires an external reference current circuit for accurate touch measurements, and the parallel master port (PMP) pins (PMA0-PMA6, RPF0-RPF6) cannot be reassigned by PPS. Programming requires ICSP or JTAG via PGECx/PGEDx pairs - choose a pair and use both pins to avoid debugger connection failures.
