PIC16LF15375-E/MV Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM), and programmable peripherals into one package. PIC16 8-bit microcontrollers occupy the entry-level to mid-tier segment of the embedded market, balancing low cost, deterministic execution, and ultra-low power consumption. Within Microchip's taxonomy, the PIC16LF15375 belongs to the PIC16(L)F153xx family of eXtreme Low-Power (XLP) devices that combine Intelligent Analog features with Core Independent Peripherals (CIPs), enabling complex analog and timing tasks without burdening the CPU.
Key features include eXtreme Low-Power (XLP) technology with typical sleep currents under 1 uA, a peripheral pin select (PPS) system that remaps digital functions onto any I/O, a 10-bit ADC with computation, a 5-bit DAC, four Configurable Logic Cells, and a Memory Access Partition (MAP) scheme for bootloader and data EEPROM emulation. The 4xPWMs combined with the CWG support motor control, half-bridge drivers, and complementary waveforms with dead-band control.
Typical applications span IoT sensor nodes, battery-powered handheld instruments, home appliances, LED lighting controllers, low-end motor control (BLDC, fans), automotive body electronics, and capacitive-touch user interfaces. The wide operating voltage window and rich peripheral set also make it well suited for industrial control nodes on 24V systems via onboard regulation.
When designing with this part, ensure the chosen debug header matches the MV package pinout (40-pin UQFN), allocate PPS assignments early to avoid conflicts, and follow Microchip AN1979 (XLP design checklist) for sleep-mode leakage budgets. Compared with switching regulator power trees, the LF variant's 1.8V minimum enables direct connection to single-cell Li-Ion or 2xAA chemistries without boost conversion.

Typical Applications
PIC16LF15375-E/MV is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, Home Appliance Control Boards, LED Lighting and Signage Controllers, Capacitive-Touch User Interfaces, Low-End BLDC Motor and Fan Control, Industrial Sensor Transmitters (4-20 mA / 0-10 V).
Battery-Powered IoT Sensor Nodes
The PIC16LF15375-E/MV is well suited to battery-powered IoT sensor nodes because its 1.8-3.6 V supply window permits direct connection to 2xAA alkaline or single-cell Li-Ion chemistries. With sub-1uA XLP sleep current and the four Configurable Logic Cells (CLC) able to wake the MCU on external sensor events without waking the CPU, the part achieves years of runtime on a coin cell. The integrated 10-bit ADC with computation provides oversampling and averaging for low-noise sensor measurements, while two EUSARTs host UART-connected radios (LoRa, BLE modules, Sub-GHz transceivers) without burdening the 32 MHz CPU. PPS allows remapping of EUSART, SPI, and I2C to any I/O pin, simplifying PCB layout on space-constrained sensor PCBs.

Home Appliance Control Boards
In washing machines, dishwashers, refrigerators, and air conditioners, the PIC16LF15375-E/MV serves as the main user-interface and motor-control MCU. The Complementary Waveform Generator (CWG) provides dead-band-controlled complementary outputs that directly drive half-bridge MOSFET drivers in motor and relay circuits, while four 10-bit PWMs control fans and pumps with closed-loop feedback. The two on-chip comparators support zero-cross detection and overcurrent protection. With 14 KB Flash it can hold application firmware plus a USB-less bootloader using the Memory Access Partition feature. Industrial temperature rating (-40 to +125 C) ensures reliable operation in appliance compartments.
Recommended
LED Lighting and Signage Controllers
The PIC16LF15375-E/MV drives multi-string LED lighting and signage installations with its four 10-bit PWM channels, each capable of 1.024 ms period resolution at 32 MHz. The CLCs can be configured as PWM combiners or fade engines that operate autonomously, offloading animation logic from the CPU to free MIPS for higher-level protocols. With dual EUSART and I2C interfaces, the MCU hosts DMX-512-A, DALI 2.0, or I2C-controlled LED driver ICs simultaneously. XLP sleep current under 1 uA enables battery-backed emergency lighting that remains quiescent until a power-good signal wakes the chip, a critical capability for code-compliant egress lighting systems.
Recommended
Capacitive-Touch User Interfaces
The PIC16LF15375-E/MV implements cost-effective capacitive-touch keypads and sliders using its mTouch peripheral library integrated with the on-chip comparators and CLCs. Each CLC operates autonomously to detect touch events without CPU intervention, allowing the MCU to remain in XLP sleep until a button press occurs, dramatically reducing average current consumption. The 5-bit DAC provides threshold calibration, while the 10-bit ADC reads touch signals at low scan rates. With Peripheral Pin Select, every I/O can become a touch channel, supporting matrices of 16+ keys on a single MCU.
Recommended
Low-End BLDC Motor and Fan Control
The PIC16LF15375-E/MV directly controls small brushless DC (BLDC) motors and fans using its Complementary Waveform Generator (CWG) and four PWMs in a six-step commutation scheme. The CWG outputs complementary gate signals with programmable dead-band time, eliminating shoot-through and allowing direct drive of low-side gate drivers. Two comparators sense back-EMF for sensorless commutation in fan applications. The 5-bit DAC provides an adjustable reference for overcurrent and stall protection. With 14 KB Flash, designers can implement sensorless FOC algorithms or simpler trapezoidal control within the program space budget.
Recommended
Industrial Sensor Transmitters (4-20 mA / 0-10 V)
The PIC16LF15375-E/MV forms the digital core of 4-20 mA loop-powered and 0-10 V industrial sensor transmitters. The 10-bit ADC samples bridge sensors, RTDs, or 4-20 mA signals, while the 5-bit DAC generates loop-excitation or 0-10 V outputs with calibration stored in 256 B EEPROM. XLP technology keeps the MCU in sub-1uA sleep until loop current is present, maximizing compliance voltage budget for the analog front end. PPS allows the same PCB layout to serve different transmitter types simply by firmware configuration, reducing SKU proliferation for instrumentation OEMs.

Design Notes
PIC16LF15375-E/MV is a low-voltage LF variant operating from 1.8 V to 3.6 V. Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin and the exposed thermal pad, which must be soldered to a continuous ground plane. For battery-powered designs, follow Microchip AN1979 (XLP Design Checklist) to budget sleep current; remember that ADC, I2C pull-ups, and floating digital inputs each add leakage paths that can defeat sub-1uA sleep budgets.
The 40-UQFN (MV) package measures 5 mm x 5 mm with a central exposed thermal pad (EP). Use a land pattern with at least 8 thermal vias stitching the EP to the ground plane to keep thermal resistance (theta_JA) low. Route PPS-mapped signals (EUSART, SPI, I2C) to keep them away from high-edge-rate PWM outputs to avoid coupling; allocate PPS pin assignments early in firmware planning to prevent late-stage conflicts during PCB layout.
Estimated: An unconfigured PPS register leaves peripherals on default pin assignments that may not match the schematic, causing silent firmware failures. Always confirm in code review that the PPSLOCK register is properly sequenced (write PPSLOCKED-bit pattern, wait for unlock, configure PPS, then re-lock). Also note that the LF and F variants differ only in VDD range; do not assume firmware developed on the F variant will run on the LF at voltages below 2.3 V without revalidation.
Compliance Information
