PIC16F15375T-I/PT Overview
An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, RAM, non-volatile program memory, and peripherals on one die. The "8-bit" refers to the width of its data path and ALU; 8-bit PIC MCUs use a modified Harvard RISC architecture optimized for deterministic interrupt response, low power, and ease of use. PIC16F1xxx devices sit in the mid-range PIC family, balancing cost, code density (14-bit instruction word), and rich on-chip peripherals for embedded control tasks. They are commonly used as the main system controller in IoT nodes, sensor hubs, and consumer appliances, or as co-processors for housekeeping and user-interface tasks.
Key features of the PIC16F15375 include 14KB Flash, 1KB SRAM, up to 36 digital I/O pins, a 10-bit ADC, multiple 8/10-bit DACs, four PWM outputs with Complementary Waveform Generator (CWG), comparators, two EUSART, SPI, and I2C. eXtreme Low-Power features such as Idle and Sleep modes, peripheral module disable, and nanoWatt XLP technology make it well-suited to battery-powered products. The 32 MHz internal oscillator removes the need for an external crystal in many designs.
The device uses the enhanced mid-range PIC16 core with a 14-bit instruction set, hardware multiply assist, and a vectored interrupt controller. Internal data EEPROM emulation through Flash, a configurable logic cell (CLC), and signal measurement timers (SMT) provide Core Independent Peripherals that offload the CPU. Intelligent analog peripherals allow closed-loop control without an external ADC/DAC chain, reducing BOM cost on sensor and motor-control boards.
Typical applications include low-power IoT sensor nodes, home automation controllers, battery-powered handheld instruments, LED lighting controls, motor-control front ends, and human-machine interface (HMI) panels. The combination of XLP, 5.5V tolerance, and rich analog peripherals makes it especially attractive for industrial sensor conditioning and small appliances.
When designing, ensure VDD decoupling uses a 100 nF ceramic capacitor placed within 5 mm of the IC. Use the ICSP header for production programming; for low-power designs, enable the watchdog timer and use Sleep with peripheral interrupts to achieve microamp standby currents. Verify that any unused I/O pins are configured as outputs low to minimize current leakage on the TQFP-44 package.

Typical Applications
PIC16F15375T-I/PT is suitable for 7 applications: Low-Power IoT Sensor Node, Home Automation Controller, Battery-Powered Handheld Instrument, LED Lighting and Signage Control, Small Motor Control Front End, Industrial Sensor Conditioning Board, Human-Machine Interface (HMI) Panel.
Low-Power IoT Sensor Node
The PIC16F15375T-I/PT fits low-power IoT sensor nodes because its XLP nanoWatt Sleep modes drop standby current to the sub-microamp range, and the 10-bit ADC plus 8/10-bit DACs perform direct sensor conditioning without external analog front ends. Operating from 2.3V to 5.5V, it works directly from a single-cell Li-ion or 2xAA battery stack. In a typical node, the MCU sleeps with peripherals off, wakes on an SMT- or INT-driven event to read the sensor via the ADC, transmits over an SPI/I2C-attached radio, and returns to Sleep. The Core Independent Peripherals (CLC, CWG, SMT) handle timing-critical tasks without CPU wakeups, further extending battery life.
Recommended
Home Automation Controller
The PIC16F15375T-I/PT suits home automation controllers thanks to 36 I/O pins, two EUSART, SPI, and I2C for connecting to relays, keypads, displays, and wireless modules. Its 14KB Flash comfortably fits protocol stacks (Zigbee gateway glue, Modbus, MQTT-edge) and the on-chip CWG generates precise timing of triac-driving PWMs for AC dimmer outputs. The 32 MHz core handles UI refresh on character LCDs while still leaving cycles for background communication. Industrial -40C to +85C rating allows deployment in utility rooms where temperature swings are common.
Recommended
Battery-Powered Handheld Instrument
The PIC16F15375T-I/PT powers battery-driven handheld instruments such as multimeters, IR thermometers, and portable gas detectors. The 2.3V to 5.5V supply range lets the device run from 2xAA or a single Li-ion cell, while XLP Sleep and peripheral module disable keep quiescent current low between measurement bursts. The on-chip 10-bit ADC reads the sensor front end, the DAC drives excitation sources, and the EUSART links to BLE or USB-to-UART bridges. The 32 MHz core and 1KB SRAM support small UI libraries and a buffer for streaming measurements to the host.
Recommended
LED Lighting and Signage Control
The PIC16F15375T-I/PT drives LED lighting and signage where the Complementary Waveform Generator (CWG) produces dead-time-aware complementary PWM outputs to switch high-side / low-side FETs efficiently. With four PWMs, the part can address RGBW strips or multi-channel signage. The 8/10-bit DAC and comparators close the loop on LED current sensing without external op-amps. XLP Sleep mode lets dimmer controllers stay alive all night on standby while still responding to button or wireless events within milliseconds.
Recommended
Small Motor Control Front End
The PIC16F15375T-I/PT functions as a small motor-control front end, particularly for brushed DC, BLDC commutation, or stepper drivers where its CWG generates complementary PWMs with programmable dead-time to safely switch half-bridges. The on-chip comparators and 10-bit ADC close current / back-EMF loops without external components, while the CLC combines PWM and comparator signals for hardware fault response. The 32 MHz instruction rate is enough for moderate-speed commutation, and the 14KB Flash holds lookup tables and PI-controller code.
Recommended
Industrial Sensor Conditioning Board
The PIC16F15375T-I/PT fits industrial 4-20mA loop-powered sensor boards because it operates at 2.3V minimum, includes a 10-bit ADC, multiple DACs, and comparators that implement signal conditioning without external analog. The -40C to +85C industrial temperature range is well-suited to factory environments, and the 5.5V tolerance survives the transients common on 24V industrial buses (with external clamping). EUSART and I2C allow easy integration to backplane PLCs and remote I/O modules, while the 14KB Flash accommodates Modbus or proprietary protocols with calibration tables.
Recommended
Human-Machine Interface (HMI) Panel
The PIC16F15375T-I/PT drives small HMI panels by combining 36 I/O for keypads and character/graphic LCDs, two EUSART for host communication, and PWMs for backlight dimming. The 14KB Flash and 1KB RAM are sufficient for menu structures, character-lcd UI libraries, and Modbus RTU slave logic. The CLC peripheral can debounce keypad inputs in hardware, reducing CPU load. Operating from 2.3V to 5.5V, the part interfaces directly to 3.3V and 5V LCD modules without level shifters, simplifying the BOM.

Design Notes
Place a 100 nF decoupling capacitor within 5 mm of each VDD pin (pins 11, 28, 42) and a bulk 10 uF capacitor at the board supply input. The TQFP-44 has three VDD pins distributed along the package; failure to decouple all of them can cause ADC noise or voltage droop during PWM bursts. For battery applications, an LDO with low Iq (e.g. Microchip MCP1700) should follow the cell to avoid ripple from the boost converter coupling into the ADC reference.
Use a 4-layer PCB with a continuous ground plane under the TQFP-44 package to provide a low-impedance return path for the high-edge-rate PWM and SPI signals. Keep the ICSP header (ICSPCLK/ICSPDAT, MCLR on RA3) isolated from sensitive analog traces to avoid programming noise coupling into ADC measurements. Route the 32 MHz oscillator traces short and symmetric; for higher accuracy, use an external crystal on RA6/RA7 with proper load capacitors per the Microchip datasheet.
Do not leave unused I/O pins floating; configure them as outputs low or inputs with the internal weak pull-up enabled. Floating inputs can draw several microamps of leakage current each, breaking Sleep-mode power budgets. Also ensure the MCLR pin (RA3 alternate) is pulled up through a 10 kOhm resistor if not used, or tied to VDD if not needed. Finally, verify the configuration words disable the watchdog timer if not needed, since an unexpected WDT reset during Sleep wake can corrupt state in low-power designs.
The PIC16F15375T-I/PT can toggle I/O at up to 32 MHz, so SPI and EUSART lines must be length-matched and series-terminated when traces exceed ~50 mm. Place a small ferrite or resistor (22-33 ohm) in series with the SCK/MOSI lines to dampen ringing on long buses. The ADC inputs are sensitive to digital switching noise; route ADC traces away from PWM outputs and add a small RC filter (100 ohm + 100 pF) at the analog input when the source impedance is high (>1 kOhm) to avoid crosstalk.
