PIC16F15375-E/ML Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals on one die. The 8-bit PIC architecture uses a modified Harvard RISC core that executes most instructions in one cycle, and PIC microcontrollers belong to the broader category of microcontrollers -> embedded processors -> semiconductors. The '153xx generation adds CIPs such as CLC, CWG, NCO, and DSM that can operate without CPU intervention, reducing active-mode current and enabling deterministic timing.
Key specifications include 14KB Flash, 1KB SRAM, 256B EEPROM, four 10-bit PWMs with complementary outputs, a 5-bit DAC, a 10-bit ADC with computation, two comparators, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), two EUSART (with LIN), one SPI/I2C, and eXtreme Low-Power features such as IDLE/DOZE modes and nanoWatt XLP sleep currents in the order of nanoamps. Supply voltage runs from 2.3V to 5.5V (F suffix = 3V-5.5V Vdd range typical for this family).
The 44-pin QFN EP package provides excellent thermal dissipation through the exposed pad, which must be soldered to a ground pad to meet electrical and thermal specifications. The QFN-44 footprint is compact (8x8 mm typical) and supports high-pin-count I/O on a small board area, ideal for hand-held and space-constrained designs.
Typical applications include low-power IoT sensor nodes, LED lighting and signage controllers, USB-CDC/HID human-interface devices, battery-powered measurement instruments, and motor/solenoid control with the CWG. The combination of XLP, CIPs, and EUSART makes the part well suited to mains-powered or battery-powered nodes that need deterministic peripheral behaviour without waking the CPU.
When designing with this part, always solder the exposed pad to a ground plane of at least 8 thermal vias for thermal and electrical performance. Use Microchip's MPLAB X IDE with the XC8 compiler; the device is supported by the MPLAB Code Configurator (MCC) for graphical peripheral setup, which dramatically reduces firmware development time.

Typical Applications
PIC16F15375-E/ML is suitable for 6 applications: Low-Power IoT Sensor Node, LED Lighting and Signage Controller, USB HID / CDC Human Interface Device, Battery-Powered Measurement Instrument, Motor and Solenoid Control, Home Appliance User Interface.
Low-Power IoT Sensor Node
The PIC16F15375-E/ML suits battery-powered IoT sensor nodes because of its nanoWatt XLP sleep currents in the nA range, 4 Configurable Logic Cells (CLC) that can wake the part on analog events without the CPU, and 14 KB of Flash that comfortably fits BLE/Zigbee sub-GHz stack glue logic. The 2.3-5.5 V Vdd range supports direct Li-ion battery connection through a simple LDO. Two EUSART peripherals allow simultaneous sensor-bus and uplink-radio connectivity, while the 10-bit ADC with computation handles temperature, light and motion sensing on-chip. Place the QFN EP over a ground copper pour with thermal vias to maintain junction temperature during periodic radio TX bursts.
Recommended
LED Lighting and Signage Controller
The PIC16F15375-E/ML drives LED lighting and signage with its 4 PWM channels (10-bit) for dimming, 1 Complementary Waveform Generator (CWG) for half-bridge MOSFET timing, and 4 CLC cells for fault protection logic implemented entirely in hardware. The 5-bit DAC and 2 comparators enable constant-current LED driver regulation without CPU intervention, allowing the core to sleep most of the time and only wake for color/pattern updates via SPI. Its 44-pin QFN EP footprint fits inside compact downlight form factors while supporting high-channel-count LED strings.
Recommended
USB HID / CDC Human Interface Device
The PIC16F15375-E/ML forms the core of USB-HID and USB-CDC peripherals when paired with an external USB transceiver; its two EUSART ports enable CDC-ACM bridging, while 14 KB Flash supports HID report descriptors, bootloader and command parser. The 10-bit ADC with computation handles analog joystick or button-matrix scanning, and the CLC cells debounce mechanical inputs in hardware so the CPU can remain in IDLE mode. The 44-pin QFN EP package minimizes PCB footprint, and the 2.3-5.5 V range allows direct USB 5V or 3.3V regulated rail operation.
Recommended
Battery-Powered Measurement Instrument
The PIC16F15375-E/ML powers portable measurement instruments (multimeters, dataloggers, field testers) thanks to its 14 KB Flash for calibration tables and UI state machines, 1 KB SRAM for measurement buffers, and the 10-bit ADC with computation that performs oversampling and averaging in hardware. The 5-bit DAC and 2 comparators generate and detect precise threshold crossings for battery-test or sensor-stimulation waveforms. nanoWatt XLP allows a year-long shelf life on coin cells when the unit is dormant, and the -40C to +125C operating range supports outdoor and industrial field use.
Recommended
Motor and Solenoid Control
The PIC16F15375-E/ML drives small DC motors, steppers and solenoids using its Complementary Waveform Generator (CWG) for dead-band-correct half-bridge timing, 4 PWM channels (10-bit) for speed/duty control, and 4 CLC cells that implement cycle-by-cycle current limiting in hardware. Two EUSART ports allow communication with a host PLC or HMI while motor control loops run autonomously via CIPs. The 44-pin QFN EP footprint fits inside BLDC driver modules, and the extended -40C to +125C operating temperature handles under-hood automotive and industrial cabinet environments.
Recommended
Home Appliance User Interface
The PIC16F15375-E/ML builds touchscreen-less home appliance UI boards (washers, ovens, microwaves) using its 14 KB Flash for state machines and LCD segment drivers, plus 4 PWM channels for buzzer and indicator LED brightness control. The CLC cells implement capacitive touch or matrix-keypad scan autonomously, letting the core enter IDLE between button events. Two EUSARTs connect to the main appliance controller board and a service/diagnostic port, and the -40C to +125C extended temperature range handles behind-panel thermal rise. The QFN EP footprint fits behind 7-segment LCD modules.

Key Differentiators
- Balanced Flash-to-pin ratio for the 44-pin QFN EP package (vs PIC16F15356-E/ML)
- Industrial / commercial -40C to +125C operating range (vs PIC16F15376-I/ML)
- 1 KB SRAM matches peripheral count more efficiently than 15385 (vs PIC16F15385-E/ML)
Design Notes
The 44-pin QFN EP package dissipates heat through the exposed pad (pin 45). Solder the EP to a PCB ground pad of at least 25 mm^2 connected by 8-12 thermal vias (0.3 mm drill, 0.5 mm pitch) to the inner ground plane. Without proper EP soldering the junction temperature can rise 20-30 C above the datasheet figure, causing derated performance or thermal shutdown. Estimated: at 32 MHz CPU and full peripheral activity, power dissipation is around 15-20 mW; the EP keeps theta_JA below ~30 C/W on a standard 4-layer 1 oz copper JEDEC test board.
Place a 0.1 uF decoupling capacitor within 3 mm of each Vdd pin (pins 7 and 43) and a bulk 1-10 uF tantalum or ceramic on the supply rail close to the MCU. The QFN EP ground pad doubles as the second Vss return; route high-speed signals (OSC, EUSART) over a continuous ground plane to avoid ground bounce. Keep the ICSP CLK/DAT lines (RB6/RB7) short and protected with series resistors to ease in-circuit programming.
Do not leave the MCLR pin floating - always tie it to Vdd through a 10 kohm pull-up and add a 100 nF cap to ground for noise immunity, or use the internal MCLR via CONFIG. The OSC1/OSC2 pins must be left open or configured as digital I/O if you select the internal HFINTOSC; a floating unused crystal pin can pick up noise and cause spurious clock anomalies. Avoid routing analog ADC inputs near PWM outputs to prevent switching noise coupling into measurements; use the ADC's computation mode with oversampling for clean readings.
