PIC16F15375-I/PT Overview
A microcontroller (MCU) is a single-chip computer containing a CPU, memory (Flash/RAM/EEPROM), and programmable peripherals used to control embedded systems. The PIC16F15375 family sits in the hierarchy: PIC16F15375 -> 8-bit PIC MCU -> microcontroller -> semiconductor IC. It targets low-power applications where active current, sleep current, and peripheral integration dominate the design trade-off, with a supply range spanning 2.3 V to 5.5 V (at reduced clock speed at low voltage).
Key features include 4 PWM channels, a 12-bit ADC with Computation, a 5-bit DAC, a comparator, Complementary Waveform Generator (CWG), two EUSART modules, and SPI/I2C communication. XLP technology provides deep-sleep currents in the nanoampere range and active currents below 50 uA/MHz, enabling battery-powered designs that run for years on a single cell.
The PIC16F15375 architecture uses a Harvard RISC core with a 14-bit instruction word, 49 instructions, and a 32 MHz internal oscillator that requires no external crystal. Core Independent Peripherals (CIPs) such as CWG, NCO, and configurable logic cells offload timing-critical tasks from the core, freeing the CPU for application logic and improving system determinism.
Typical applications include IoT sensor nodes, low-power wireless sensor platforms, battery-powered home automation, motor control with PWM, lighting control, and small consumer appliances. The combination of low power, integrated analog, and abundant communication peripherals makes it well-suited to designs that must wake, sense, communicate, and return to sleep with minimal energy.
When designing with this device, ensure the supply voltage matches the chosen clock speed: full 32 MHz operation requires 3.0 V or higher, while 16 MHz is supported down to 2.3 V. Use the MPLAB X IDE and MPLAB XC8 compiler for code development, and Microchip's Code Configurator (MCC) for visual peripheral setup.

Typical Applications
PIC16F15375-I/PT is suitable for 6 applications: Battery-Powered IoT Sensor Node, Home Automation Lighting Control, Small Motor and Fan Control, Wearable Health Monitoring Device, Industrial Sensor Transmitter, Low-Power Remote Control.
Battery-Powered IoT Sensor Node
The PIC16F15375-I/PT is a strong fit for battery-powered IoT sensor nodes where multi-year battery life and integrated analog dominate the BOM. Its XLP sleep current in the nanoampere range (below 100 nA with RAM retention) and active current below 50 uA/MHz at 32 MHz let the device wake, sample, transmit, and return to sleep with minimal energy budget. The 12-bit ADC with Computation handles sensor conditioning without a dedicated analog front end, and 1 KB RAM is sufficient to buffer wireless protocol stacks such as LoRaWAN or BLE before transmission. Two EUSARTs and SPI/I2C allow pairing with sub-GHz radio modules, BLE modules, or sensor hubs. Pair with a single lithium coin cell (CR2032) for multi-year deployments in remote or inaccessible locations.

Home Automation Lighting Control
The PIC16F15375-I/PT's 4 PWM channels, 12-bit ADC, and Complementary Waveform Generator (CWG) make it a natural choice for dimmable LED lighting and home automation controllers. The CWG generates hardware-based complementary PWM dead-band control for half-bridge drivers, offloading switching timing from the CPU and eliminating jitter in dimming transitions. Two EUSARTs support simultaneous connectivity to a wired DMX/dimming bus and a wireless link (Zigbee or BLE) for hybrid lighting networks. XLP technology enables wall-switch products that consume negligible standby current. The 14 KB Flash holds a Zigbee or proprietary RF stack plus lighting control logic. The wide 2.3 V to 5.5 V supply range simplifies designs powered from 3.3 V or 5 V rails.
Recommended
Small Motor and Fan Control
For BLDC, brushed DC, and small induction motor control, the PIC16F15375-I/PT delivers the timing precision needed without an external DSP. Its Complementary Waveform Generator (CWG) creates dead-band-corrected complementary PWM signals suitable for driving half-bridges in three-phase BLDC motors, with hardware-level protection that offloads switching logic from the core. Four PWM channels support fan tachometer feedback, speed control loops, and current sensing trigger timing. The 12-bit ADC with Computation implements hardware averaging of back-EMF and current-sense signals, reducing CPU load. At 32 MHz, the device closes the PID loop in microseconds for smooth torque and speed response in compact BLDC fans and pumps.
Recommended
Wearable Health Monitoring Device
The PIC16F15375-I/PT targets wearable health and fitness devices where every microampere matters. Its XLP sleep current (under 100 nA) lets the device sit idle between sensor samples, while the integrated 12-bit ADC reads heart-rate, SpO2, or motion sensors directly. The 5-bit DAC drives a haptic feedback driver or LED indicator for user alerts without extra silicon. Two EUSARTs and SPI/I2C support BLE modules or display drivers. With 14 KB Flash, the MCU accommodates a lightweight sensor-fusion algorithm alongside a Bluetooth Low Energy profile. The wide 2.3 V to 5.5 V supply range allows operation from a small Li-ion battery across its full discharge curve.
Recommended
Industrial Sensor Transmitter
Industrial 4-20 mA sensor transmitters, RTD conditioners, and process-control nodes benefit from the PIC16F15375-I/PT's combination of analog integration, low power, and industrial temperature grade. The 12-bit ADC with computation pairs with op-amps to digitize thermocouple, RTD, or bridge sensor signals at high accuracy, while the 5-bit DAC and PWM channels generate 4-20 mA loop excitation. The Industrial -40C to +85C temperature rating covers factory-floor environments. EUSART and SPI peripherals drive RS-485 transceivers for Modbus RTU or 4-20 mA HART modems. The 14 KB Flash holds a Modbus stack or HART state machine, with 1 KB RAM for buffer and protocol state.
Recommended
Low-Power Remote Control
Battery-powered remote controls for TVs, garage doors, and security systems rely on long battery life and reliable wireless links. The PIC16F15375-I/PT's nanoampere sleep current and sub-50 uA/MHz active current let coin-cell remotes last 5+ years. The 12-bit ADC reads battery voltage for accurate low-battery detection, while the CWG and PWM channels generate IR modulation signals or RF subcarrier waveforms. Two EUSARTs support bidirectional feedback channels. The 14 KB Flash is enough to hold button-mapping tables, RF protocol stacks, and power-management logic. The wide supply range lets the same design run from CR2032 or AAA cells without modification.

Design Notes
The PIC16F15375-I/PT supports input voltages from 2.3 V to 5.5 V, but full 32 MHz operation requires VDD at or above 3.0 V. Below 3.0 V, the maximum CPU clock is limited to 16 MHz. For battery-powered designs, plan the system voltage so the MCU can still operate at the desired frequency during battery discharge. Add bulk capacitance (at least 10 uF) near the VDD pins and a 100 nF decoupling capacitor on each VDD pin to suppress switching transients during PWM events.
At typical low-power operating currents in the 5-15 mA range, internal power dissipation is well under 100 mW and thermal management is not required. However, if the device is operated at 32 MHz with all peripherals active and high PWM switching rates, package self-heating becomes measurable. Route the TQFP-44 ground paddle (if used) or multiple VSS pins to a generous copper pour to spread heat. Industrial temperature parts (I suffix) operate from -40C to +85C; for higher operating temperatures, choose the E suffix variant (-40C to +125C).
Route the 32 MHz external oscillator traces (RA6/OSC2 and RA7/OSC1) as short as possible and surround them with a ground guard ring to avoid coupling digital noise into the high-impedance oscillator cell. If using the internal 32 MHz HFINTOSC, configure the OSCTUNE register to compensate for frequency error. Place the ICSP programming pins (RB6/ICSPCLK, RB7/ICSPDAT) so a PICkit 4 or Snap header can be reached without disturbing the PCB. For RF designs, keep the MCU away from the antenna and route clock lines orthogonal to RF traces.
Do not assume the device runs at 32 MHz below 3.0 V - the maximum frequency drops to 16 MHz at 2.3 V and code that depends on timing must be re-verified at low voltage. MCLR must never be left floating; tie it to VDD through a 10 kohm resistor or use the internal MCLR disable configuration. The A/D converter requires a sufficient acquisition time; do not skip the ACQT bits configuration or readings will be inaccurate. When using the CWG, verify the dead-band timing registers against the half-bridge driver's propagation delay - insufficient dead-band causes shoot-through.
Keep analog and digital ground separated at the schematic level and join them at a single point under the MCU's VSS pin. Place the 100 nF VDD decoupling capacitor within 5 mm of each VDD pin, with the ground return directly to the nearest VSS pin. For designs using the 12-bit ADC, route analog signal traces away from PWM outputs and clock lines; place a ground guard ring around the analog input pins. When using SPI or I2C, add series resistors near the MCU pins to dampen ringing on long traces.
Compliance Information
