PIC32MX110F016BT-V/SO Visão geral
A 32-bit microcontroller (MCU) is a programmable computing element that executes instructions from on-chip Flash memory, drives digital I/O, and interfaces with analog peripherals such as ADC, comparators and timers. PIC32MX1x0 devices sit at the low-memory end of the broader PIC32 family — they extend Microchip's PIC architecture into 32-bit territory while preserving the MPLAB X IDE and Harmony ecosystem. They are descendants of the original PIC microcontroller line, which established the 8-bit MCU category, and represent the migration path into higher-performance MIPS-based silicon for embedded designs.
Key features include a single-core MIPS32 M4K CPU running up to 40 MHz with < 0.5 mA/MHz active current, on-chip 10-bit ADC, two I²S/SPI modules for audio codec connectivity, Peripheral Pin Select (PPS), a Parallel Master Port (PMP) for graphics interfaces, and a Charge Time Measurement Unit (CTMU) supporting mTouch™ capacitive touch buttons and sliders. Five 16-bit general-purpose timers and DMA channels enable offloading of repetitive data movement.
Architecturally, the device uses Harvard-style separated instruction/data buses with a 5-stage pipeline, single-cycle multiply and hardware divider, and tightly-coupled peripheral buses. USB 2.0 full-speed, I²C, UART, SPI, and PMP peripherals share pins through the PPS multiplexer, simplifying PCB routing in compact 28-pin layouts.
Typical applications include automotive body electronics, industrial control panels, consumer audio peripherals, USB HID devices, and low-cost graphical user interfaces driving small LCDs. The wide operating voltage range and -40 °C to +105 °C thermal envelope also suit outdoor IoT edge nodes.
When designing with this MCU, ensure decoupling uses 100 nF + 10 µF placed within 5 mm of the VDD pins; PPS reassignments must be configured at runtime and unlocked via IOLOCK before peripheral changes. The 'T' suffix denotes tape-and-reel packaging; the 'V' temperature code designates the -40 °C to +105 °C automotive-grade window.

Aplicações típicas
PIC32MX110F016BT-V/SO é adequado para 6 aplicaçãos: Automotive Body Control Modules, USB HID Consumer Devices, Industrial HMI Panels, Capacitive Touch Control Boards, Audio Peripherals and Codec Interfaces, Outdoor IoT Edge Nodes.
Automotive Body Control Modules
The PIC32MX110F016BT-V/SO is well suited for automotive body control thanks to its AEC-Q100 Grade 3 qualification, 2.3 V to 3.6 V supply, and -40 °C to +105 °C operating window. Its 40 MHz MIPS32 M4K core executes CAN/LIN software stacks and PWM signal conditioning for door, mirror and lighting loads. With 16 KB Flash and 4 KB SRAM, the device fits typical BCM firmware plus a bootloader, while the 21 GPIO accommodate H-bridge drivers and switch inputs. PPS routing simplifies PCB layout by remapping peripherals to spare pins without board re-spins. The 10-bit ADC supports battery voltage and current sensing at automotive load-dump conditions.
Recomendado
USB HID Consumer Devices
The integrated USB 2.0 full-speed device controller with on-chip transceiver makes this MCU ideal for low-cost USB HID peripherals such as keyboards, mice, game controllers and custom input devices. The 40 MHz core is sufficient for HID class polling at 1 kHz plus debounce and LED animation, while 4 KB SRAM holds HID report buffers and protocol state machines. PPS allows flexible assignment of the USB D+/D- and VBUS sense pins. The wide 2.3 V to 3.6 V supply range lets designers power the device directly from a 3.3 V LDO fed by USB VBUS. DMA channels offload repetitive endpoint transfers to free the CPU for application code.
Recomendado
Industrial HMI Panels
With its Parallel Master Port (PMP), the PIC32MX110F016BT-V/SO drives small graphical LCDs and OLEDs in industrial human-machine-interface panels. The PMP interface supports 8-bit or 16-bit data plus control signals for typical graphic controllers, eliminating external glue logic. Five 16-bit timers generate PWM backlight dimming and key-scan waveforms, while 4 KB SRAM buffers graphics frame updates. The -40 °C to +105 °C temperature grade supports factory-floor and outdoor cabinet installations. PPS reassignment of UART and SPI peripherals lets designers move debug ports without altering PCB routing.
Recomendado
Capacitive Touch Control Boards
The on-chip Charge Time Measurement Unit (CTMU) enables Microchip's mTouch™ capacitive sensing libraries, supporting touch buttons, sliders and proximity sensors without external touch ICs. The CTMU works with the 10-bit ADC to measure capacitance changes in real time, and the MIPS32 core runs the mTouch decode and filtering algorithms in firmware. PPS routing of the ADC channels simplifies PCB layout when sensors are scattered across the enclosure. The 16 KB Flash comfortably holds the touch library plus application code, and the 2.3 V to 3.6 V supply allows operation from a single Li-Ion cell or 3.3 V regulated rail.
Recomendado
Audio Peripherals and Codec Interfaces
Two I²S/SPI modules let the PIC32MX110F016BT-V/SO act as a low-cost audio controller for Bluetooth codecs, S/PDIF bridges and digital microphone arrays. The MIPS32 M4K core runs lightweight audio mixing or echo-cancellation firmware in 4 KB SRAM, while the DMA channels stream sample data to and from the I²S peripherals without CPU intervention. The 28-SOIC footprint supports compact soundbar and headphone designs. AEC-Q100 qualification opens audio-replacement-module opportunities in automotive infotainment where two-channel line-level switching is needed.
Recomendado
Outdoor IoT Edge Nodes
The -40 °C to +105 °C temperature range and sub-20 µA sleep current make the PIC32MX110F016BT-V/SO a fit for outdoor IoT edge nodes such as smart meters, environmental loggers and asset trackers. The 16 KB Flash stores the metering algorithm plus a wireless protocol stack fragment, while the 10-bit ADC digitizes battery voltage, temperature and load sensors. PPS allows remapping of UART-based NB-IoT or LoRa module interfaces to spare GPIO without board rework. The AEC-Q100 grade is a bonus for fleet-vehicle telematics and rugged industrial monitoring.

Notas de projeto
Place a 100 nF X7R decoupling capacitor within 5 mm of each VDD pin (7, 20, 28) and a single 10 µF bulk capacitor on the 3.3 V rail. The PIC32MX110 core draws sub-50 mA active peaks, so use a low-ESR ceramic bulk cap to suppress USB inrush transients. Tie all three VSS pins (8, 19, 27) to a continuous ground pour to keep digital return currents low-impedance.
Route the ICSP PGEC1/PGED1 pair (pins 3/2) directly to an in-circuit programming header with no series resistors; the ICSP interface is the only way to recover a locked-out device. Keep the 28-SOIC footprint on a 7.50 mm body with 1.27 mm pitch to match Microchip's recommended land pattern, and route the USB D+/D- (pins 21/22) as a 90-ohm differential pair with no stubs.
Peripheral Pin Select (PPS) mappings must be unlocked by writing 0x55 and 0xAA to CFGKEY before changing remappable registers — a common firmware bug leaves peripherals silent. The 'T' suffix indicates tape-and-reel packaging; do not confuse it with a silicon revision. The 'V' temperature code (-40 °C to +105 °C) and the 'I' industrial grade (-40 °C to +85 °C) are not interchangeable in automotive designs — pick the V suffix for AEC-Q100 deployments.
Informações de conformidade
V temperature suffix indicates AEC-Q100 Grade 3 qualification per Microchip product page. RoHS and REACH compliant per DigiKey/LCSC distributor listings.
