PIC16LF15375-I/PT Visão geral
What is an 8-bit PIC microcontroller? An 8-bit MCU (microcontroller unit) is a single-chip computer that processes data 8 bits at a time, combining a CPU, non-volatile Flash memory, SRAM, and configurable peripherals on one die. The PIC16F family sits in the hierarchy of small-form-factor microcontrollers -> microcontrollers -> embedded processors -> semiconductor ICs, optimized for cost-sensitive, low-power, real-time control applications. The PIC16LF15375 belongs to the 'LF' low-voltage sub-family that operates down to 1.8 V.
Key specifications include a 1.8 V to 3.6 V operating voltage range, two Enhanced USART modules supporting LIN/IrDA/RS-485, SPI and I2C master/slave peripherals, a 10-bit ADC with computation (ADC2), a 5-bit DAC, two comparators, and a 32 MHz internal oscillator with ±1% accuracy. The CWG and NCO combine to produce precision waveforms without CPU intervention, reducing firmware load and power consumption in motor control and lighting applications.
Architecturally, the PIC16LF15375 uses a RISC-style Harvard architecture with a single-cycle instruction execution, allowing most instructions to complete in one oscillator period (31.25 ns at 32 MHz). Core Independent Peripherals (CIPs) operate without CPU intervention, enabling deterministic real-time responses. The XLP technology delivers nanoWatt sleep currents, making the device ideal for battery-powered applications requiring years of operation on a single cell.
Typical applications include IoT sensor nodes, low-power wireless devices, LED lighting controllers, battery management systems, home appliances, and consumer electronics requiring USB or touch sensing interfaces. The wide peripheral mix also suits industrial control and automotive body electronics subsystems.
When designing with the PIC16LF15375-I/PT, allocate sufficient decoupling (100 nF per VDD pin), keep traces short for the 32 MHz clock, and use Microchip's MPLAB X IDE with XC8 compiler. The 44-TQFP (10x10 mm) footprint simplifies hand-prototyping and rework.

Aplicações típicas
PIC16LF15375-I/PT é adequado para 6 aplicaçãos: IoT Sensor Nodes & Wireless Endpoints, LED Lighting Controllers & Drivers, Battery Management Systems, Home Appliance Control Panels, Consumer Electronics & Wearables, Industrial Sensor & Process Transmitters.
IoT Sensor Nodes & Wireless Endpoints
The PIC16LF15375-I/PT fits IoT sensor nodes where every microamp matters. Its nanoWatt XLP technology delivers sleep currents below 1 uA with RTC running, allowing coin-cell-powered nodes to operate for years. The 32 MHz core wakes in microseconds to service sensor reads, while Core Independent Peripherals (CLC, NCO) handle wake-on-event logic without CPU load. The 1.8-3.6 V range supports direct Li-ion or 2xAA cells, and 14 KB Flash accommodates BLE/Zigbee stack fragments or LoRaWAN application code. EUSART/SPI/I2C map to wireless modules (RN4871, SAM R34) via Peripheral Pin Select, keeping the 44-TQFP footprint manageable.
Recomendado
LED Lighting Controllers & Drivers
The PIC16LF15375-I/PT serves as a digital LED controller where the Complementary Waveform Generator (CWG) and four 10-bit PWMs drive multi-channel LED strings with deterministic timing. The 32 MHz CPU and CIPs offload dimming curves and color-mixing math, leaving the core free for DMX-512 / DALI / 0-10 V protocol handling via EUSART. The 1.8-3.6 V operation suits 3.3 V regulated rails, and the 36 I/O pins in 44-TQFP support daisy-chained LED drivers (TLC59401, LP8860) without extra glue logic. nanoWatt sleep modes enable standby under 5 uA for always-connected fixtures.
Recomendado
Battery Management Systems
The PIC16LF15375-I/PT is well-matched to battery management systems (BMS) for single-cell Li-ion and 2-3 cell NiMH packs. Its 10-bit ADC2 with computation performs autonomous voltage, current, and temperature scanning without CPU intervention, while the CLC combines comparator outputs for over-current protection hardware trip. The 1.8-3.6 V range operates directly from a single Li-ion cell across the full discharge curve. The 224-byte EEPROM stores cycle count and learned fuel-gauge parameters, and the 44-TQFP footprint survives automotive under-hood thermal stress when paired with the PIC16LF15375-E/PT extended-temperature variant.
Recomendado
Home Appliance Control Panels
The PIC16LF15375-I/PT drives home appliance user interfaces (washing machines, dishwashers, ovens) where its 32 MHz performance and 36 I/O handle segmented LCD or TFT displays, touch buttons via CLC-driven scan, and brushless DC motor commutation via CWG + NCO. The 14 KB Flash supports multi-language UI and fault-logging firmware, while the 1 KB SRAM buffers LCD frames. EUSART interfaces to inverter boards or wireless modules for IoT retrofit. The 44-TQFP (10x10 mm) provides enough I/O for encoders, relays, and triac drivers in a single chip.
Recomendado
Consumer Electronics & Wearables
The PIC16LF15375-I/PT suits consumer wearables such as fitness bands, smart watches, and BLE beacons where compact PCB area and low power dominate. The 44-TQFP (10x10 mm) footprint is small enough for wrist-form-factor designs, and 14 KB Flash holds device drivers and BLE profiles. The 32 MHz MIPS/Watt ratio combined with nanoWatt XLP sleep delivers days of runtime on a 100 mAh Li-Po cell. The 10-bit ADC2 samples heart-rate / SpO2 sensors at high duty while the CWG drives haptic feedback motors without CPU wake. PPS routes I2C/SPI/UART to any pin, simplifying board layout around small enclosures.
Recomendado
Industrial Sensor & Process Transmitters
The PIC16LF15375-I/PT is a strong fit for industrial 4-20 mA loop-powered transmitters and HART-modem sensor interfaces. Its 1.8-3.6 V operation supports 3.3 V raily sensors, while the ADC2 with computation performs oversampling and digital filtering in hardware, freeing the CPU for HART or IO-Link protocol stacks. The CLC implements Manchester encoding/decoding for HART modem without external logic, and the 32 MHz core handles IO-Link SMI (Serial Multi-drop Interface) timing. The 44-TQFP package and 36 I/O allow interfacing to multiple sensor types (RTD, thermocouple, strain gauge) in one design.

Notas de projeto
Estimated: At VDD = 3.3 V and active CPU at 32 MHz, the PIC16LF15375 draws approximately 5-7 mA typical (per datasheet DC characteristics). In sleep with RTC running, XLP technology drops this to under 1 uA, enabling years of battery life on a 1000 mAh cell when wake duty is under 0.1%. Always place a 100 nF decoupling capacitor on each VDD pin and a bulk 4.7 uF tantalum within 10 mm to handle inrush during peripheral activation.
Route the 32 MHz clock traces (OSC1/OSC2) as short as possible and keep them away from switching signals. Place the ICSP pins (RB6/ICDCK and RB7/ICDDAT) on accessible test points for in-circuit debugging. Use a continuous ground plane beneath the 44-TQFP, and route analog signals (ADC, comparators) on the opposite side of digital signals with a guard trace tied to AGND to minimize crosstalk on the 10-bit ADC2 inputs.
Do not confuse the LF (1.8-3.6 V) and F (2.3-5.5 V) variants when sourcing. The PIC16LF15375-I/PT will not start reliably below 1.8 V, and the PIC16F15375-I/PT will fail to start at 1.8 V. The MCLR pin (RA3/MCLR, pin 44) requires a 10 kohm pull-up to VDD - do not leave it floating. When using Peripheral Pin Select (PPS), lock the PPS registers against accidental code writes via the PPSLOCK bit during runtime configuration.
