PIC16LF15375-I/ML Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, working RAM, and on-chip peripherals. Within the broader taxonomy, the PIC16LF15375 belongs to the 8-bit microcontroller family -> microcontrollers -> microprocessors and microcontrollers -> embedded controllers -> integrated circuits. The PIC architecture uses a Harvard RISC core with a 14-bit instruction word; the 'LF' suffix denotes the low-voltage Flash variant and the 'F' core provides single-cycle hardware multiply and deterministic interrupt latency. XLP technology integrates multiple low-power modes (sleep, deep sleep, etc.) so designers can hit nanoamp standby targets without external components.
Key features include four 10-bit PWMs with Compare mode, two comparators with 5-bit DAC references, a 5-bit/8-bit DAC, a 12-bit ADC with computation (ADC2), a Complementary Waveform Generator (CWG), four Configurable Logic Cells (CLCs), and dual EUSART plus SPI/I2C peripherals for connectivity. The part also adds Brown-out Reset (BOR), Power-on Reset (POR), and Windowed Watchdog Timer (WWDT) for safety. The 44-QFN (8x8) package exposes 36 I/O pins while keeping the board footprint compact.
Typical applications include low-power sensor nodes, battery-powered IoT endpoints, e-metering, remote controls, HVAC thermostat controls, and consumer white goods. Engineers frequently pair the PIC16LF15375 with the MCP1700 LDO, the MCP73831 Li-Ion charger, and the MCP9808 temperature sensor for a complete low-power subsystem.
When designing with this part, verify Vdd decoupling (100 nF + bulk) close to the pins, route the ICSP/ICD pins (PGD/PGC) for in-circuit debug, and use MPLAB X IDE with XC8 compiler for firmware development. The 44-QFN EP (exposed pad) must be soldered to the ground plane for thermal and electrical reference.

Typical Applications
PIC16LF15375-I/ML is suitable for 7 applications: Battery-Powered IoT Sensor Nodes, Smart Thermostats and HVAC Controls, Consumer Remote Controls, E-Metering and Sub-Metering, Industrial Sensor Transmitters (4-20 mA / 0-10V), White Goods and Home Appliance Controls, Wearables and Fitness Bands.
Battery-Powered IoT Sensor Nodes
The PIC16LF15375-I/ML fits IoT sensor nodes because its XLP nanoWatt sleep currents and 1.8V minimum Vdd let a coin cell run for years. The 12-bit ADC2 with computation offloads windowed averaging and oversampling from the CPU, while the 32 MHz core wakes quickly to process samples and transmit via a sub-GHz or BLE companion. Two EUSART/SPI/I2C ports let it sit alongside an MCP9808 temperature sensor, an MCP9700 thermistor amp, and a LoRa or BLE modem. The 44-QFN (8x8) footprint is small enough for wearable and stick-on form factors; nanoamp deep sleep ensures quiescent drain is dominated by the sensor, not the MCU.
Recommended
Smart Thermostats and HVAC Controls
HVAC thermostats need reliable ADC inputs (NTC, RTD, humidity), capacitive touch, and a real-time display - all strengths of the PIC16LF15375-I/ML. The 12-bit ADC2 with computation simplifies thermistor linearization, while the CWG and four PWMs can drive TRIAC phase-angle control for AC line dimming of fans or valves. The dual comparators with 5-bit DAC references allow zero-cross detection without external analog ICs. I2C drives an OLED or character LCD, plus a humidity sensor like the MCP9808. The wide 1.8V-3.6V range plus 44-QFN EP packaging supports sealed, low-profile in-wall enclosures.
Recommended
Consumer Remote Controls
IR/BLE remote controls are a textbook fit for the PIC16LF15375-I/ML. The 32 MHz core generates accurate 38 kHz / 40 kHz carrier waveforms via PWM and CWG with minimal CPU overhead, while deep-sleep currents below 1 uA extend AAA battery life to multi-year horizons. The 36 I/O pins handle key-matrix scanning, IR LED drive, and an optional low-energy link. SPI/I2C connect to an accelerometer for gesture remote features. The 14 KB Flash holds RC5/RC6, SIRC, NEC, or proprietary protocols plus button-remapping tables, all in the compact 44-QFN (8x8 mm) form factor.
Recommended
E-Metering and Sub-Metering
Energy meters require precise ADC sampling, isolated UART for AMR (automatic meter reading), and ultra-low sleep current for battery-backed RTC. The PIC16LF15375-I/ML's 12-bit ADC2 with oversampling and accumulation is suitable for shunt-resistor current sensing, and the CLC can implement zero-cross detection without CPU intervention. Two EUSARTs support isolated RS-485 / wired M-Bus communication to concentrators. WWDT and BOR provide the safety integrity that metering standards expect. The 44-QFN package is small enough to fit inside split-core CT housings while exposing enough I/O for tamper switches and optocouplers.
Recommended
Industrial Sensor Transmitters (4-20 mA / 0-10V)
Loop-powered 4-20 mA transmitters run from as little as 12V and need to regulate down to a usable Vdd while dissipating minimal quiescent current. The PIC16LF15375-I/ML's 1.8V minimum supply and nanoWatt sleep pair with an LDO such as the MCP1700 to drop the loop voltage efficiently. The 12-bit ADC reads the bridge sensor; the 10-bit PWM plus external filter generates the 4-20 mA loop current with proper scaling. HART or IO-Link communication can be modulated via a UART and a small analog frontend. Industrial -40C to +85C rating handles plant-floor environments.
Recommended
White Goods and Home Appliance Controls
Washing machines, dishwashers, and refrigerators need rugged motor control plus user interface handling. The PIC16LF15375-I/ML's CWG + four PWMs can drive TRIACs, BLDC sensorless starters, or universal-motor commutators, while the four CLCs implement interlocks and safety logic in hardware to offload the CPU. Brown-out Reset and WWDT satisfy IEC 60335 safety expectations. The 14 KB Flash holds appliance-specific state machines, EEPROM emulation (in Flash) preserves settings across power cycles, and the dual EUSARTs serve an external UI board plus a service/diagnostic port.
Recommended
Wearables and Fitness Bands
Wearables combine always-on sensing, low-power BLE connectivity, and a coin-cell form factor - exactly the use case the PIC16LF15375-I/ML targets. The ADC2 oversamples heart-rate / SpO2 photodiode signals, CLCs handle motion-driven interrupts from an accelerometer, and the MCU sleeps in nanoamp mode until a real event occurs. The 36 I/O supports an SPI display plus I2C sensors; the small 44-QFN (8x8) package fits wristband PCBs. Deep-sleep currents under 1 uA preserve CR2032 capacity for the device's standby life.

- Core-independent peripherals in a small package (vs PIC16LF15376-I/ML)
Design Notes
Estimated: at 32 MHz and 3.3V, active current is in the low single-digit mA range per the Microchip datasheet. Add a 100 nF + 1 uF + 10 uF decoupling network close to the Vdd pins (pins 9 and 40 on the 44-QFN). For battery-powered designs, route the MCP1700 LDO with its 1.6 uA quiescent current and use the PIC's nanoWatt sleep modes - typical deep-sleep current is below 1 uA, allowing multi-year battery life on a CR2032 for duty-cycled sensor reads.
Estimated: at room temperature the part dissipates well under 100 mW, but the 44-QFN EP (exposed pad, pin 45 - underside thermal pad) MUST be soldered to a continuous ground plane for both thermal dissipation and electrical reference. Use thermal vias under the EP per Microchip's QFN-44 PCB layout application note. Avoid placing heat sources nearby; the EP accounts for the majority of the package's heat-spreading capability.
Route ICSP signals (PGD on RB7, PGC on RB6, MCLR on RE3) with no series resistors and keep them short to the programming/debug header. Per Microchip's ICSP application note, add a small ESD diode array on these lines if the connector is exposed. Keep analog traces (ADC, comparator inputs) away from PWM/CWG switching traces to avoid digital coupling into sensitive analog readings. Place the 100 nF decoupling capacitor within 2 mm of each Vdd pin.
Do not exceed Vdd 3.6V on the LF variant - the PIC16F15375 is required above 2.3V. Always configure the unused I/O pins as outputs (low) or inputs with internal weak pull-ups to minimize sleep current. When using the ADC, allow adequate acquisition time based on source impedance per the datasheet's AC specification tables - typically 1 us for 10k source impedance. If you need EEPROM-like non-volatile storage, use Flash self-programming (EEPROM emulation library from Microchip) instead of relying on an external EEPROM.
