PIC16F15375T-I/MV 概述
An 8-bit microcontroller (MCU) is a small, self-contained computer on a single IC that integrates a CPU, non-volatile program memory (typically Flash), volatile RAM, and a configurable set of digital and analog peripherals. PIC microcontrollers use a RISC instruction set and Modified Harvard architecture, occupying a hierarchy of 8-bit MCU -> microcontroller -> embedded controller -> semiconductor. They are widely used in sensor interfaces, consumer appliances, motor control front-ends, and low-power IoT edge nodes because they deliver deterministic execution at very low active and sleep currents.
Key features include 4 PWM modules, a Comparator, a 5-bit DAC, an ADC, a Complementary Waveform Generator (CWG), 4 Configurable Logic Cells (CLC), 2 EUSART, and SPI/I2C. The device supports 1.8V-5.5V operation, enabling direct connection to single-cell Li-ion, 2xAA, and 3.3V digital rails without external level shifting. The XLP Sleep mode with nanowatt-class current extends battery life in duty-cycled applications such as remote controls and wireless sensor nodes.
The PIC16F15375 family uses a 14-bit instruction word and an internal 32 MHz oscillator, with multiple clock options for power/performance trade-off. Peripherals like CLC allow combinatorial logic to be implemented in hardware without CPU intervention, offloading real-time tasks and enabling deterministic response times for safety-sensitive signal chains.
Typical applications include IoT sensor nodes, home automation, low-power motor control (fans, BLDC commutation assistance), battery-powered consumer products, and industrial sensor hubs. The wide voltage range and rich peripheral set allow a single MCU to handle sensing, communication, and local control without external logic.
Designers should note that the 40-UQFN package includes an exposed thermal pad that must be soldered to the ground plane for mechanical reliability and thermal dissipation. Decoupling capacitors (100 nF + bulk) should be placed within a few millimeters of the VDD pins to support ADC and DAC accuracy. Migrating between PIC16F15375 variants (28/40/44/48-pin) requires re-validating pin assignments but not firmware, because the peripherals are identical across pin counts.

典型应用
PIC16F15375T-I/MV 适用于 6 应用s: IoT Sensor Node, Home Automation / Lighting Control, Battery-Powered Consumer Devices, Industrial Sensor Hub, Low-Power Motor Control Front-End, HMI / User Interface Controller.
IoT Sensor Node
The PIC16F15375T-I/MV fits IoT sensor nodes because of its eXtreme Low-Power (XLP) Sleep mode and integrated ADC. The device's nanowatt-class sleep current extends battery life on 2xAA cells to multiple years when duty-cycled. Its 4 CLCs allow pulse counting, sensor gating, and wake-event logic to be implemented in hardware without waking the CPU, while the 32 MHz core provides enough throughput to handle UART-based protocols like Modbus or lightweight sensor framing. Operating voltage of 2.3V-5.5V allows direct connection to single-cell Li-ion or 3.3V regulated rails without external level shifters.
推荐
Home Automation / Lighting Control
In home automation and lighting control, the PIC16F15375T-I/MV is well-suited because of its 4 PWM channels and Complementary Waveform Generator (CWG). The CWG can drive half-bridge or full-bridge LED driver stages with built-in dead-band control, eliminating external gate-driver logic for dimmable LED strings. The 5-bit DAC provides smooth dimming curves, while EUSART and SPI interfaces connect to wireless modules (sub-GHz, BLE) for hub integration. The 36 I/O pins are sufficient for keypad scanning, status LEDs, and zero-cross detection on mains-powered lighting PCBs.
推荐
Battery-Powered Consumer Devices
The PIC16F15375T-I/MV is ideal for battery-powered consumer devices because of its nanowatt XLP Sleep current, 2.3V-5.5V operating range, and integrated peripherals that minimize external component count. With Sleep currents measured in the nanowatt range, the device enables remote controls, electronic shelf labels, smart locks, and wearables to operate for years on coin-cell or 2xAA batteries. The 32 MHz core wakes quickly to process user inputs or wireless interrupts, then returns to sleep - critical for extending battery life in duty-cycled consumer designs where average current dominates runtime.
推荐
Industrial Sensor Hub
The PIC16F15375T-I/MV is well-matched to industrial sensor hubs because of its industrial -40C to +85C operating temperature range, 5V tolerance on digital I/O, and dual EUSART interfaces. Two EUSARTs allow simultaneous RS-485 and RS-232 connections, or a sensor bus plus a debug/UART console. The ADC with internal voltage reference provides accurate analog measurements, while CLCs handle signal conditioning for quadrature encoders or PWM-based flow sensors. Operating from 2.3V-5.5V lets the device share 3.3V or 5V industrial rails without regulators.
推荐
Low-Power Motor Control Front-End
In low-power motor control front-ends, the PIC16F15375T-I/MV's Complementary Waveform Generator (CWG) and 4 PWM channels enable direct MOSFET gate driving for small BLDC and brushed DC motors. The CWG handles dead-band insertion and complementary outputs without CPU intervention, while PWM channels manage speed and torque loops. With 32 MHz CPU throughput, the MCU can run sensorless commutation algorithms at moderate PWM frequencies. The 14 KB Flash is sufficient for state-machine based field-oriented control (FOC) lite implementations.
推荐
HMI / User Interface Controller
The PIC16F15375T-I/MV is appropriate for HMI and user interface controllers because of its 36 I/O pins and Configurable Logic Cells. The 4 CLCs can debounce keypads, generate timed sequences, and combine button events without software polling - reducing CPU load and improving responsiveness. The EUSART and SPI peripherals drive character LCDs, OLED displays, or capacitive touch controllers. Operating voltage of 2.3V-5.5V simplifies integration with both 3.3V displays and 5V legacy keypads in mixed-voltage HMI designs.

设计说明
The 40-UQFN (5x5 mm) package uses an exposed thermal pad (EP) on the underside that must be soldered to a ground copper pour for both thermal dissipation and mechanical reliability. Without proper EP soldering, the junction-to-ambient thermal resistance rises dramatically, potentially causing thermal shutdown under high I/O toggling loads. Recommended minimum EP copper area is 25 mm x 25 mm with thermal vias to the opposite plane. Estimated: at 32 MHz with all 36 I/Os toggling at 50 pF, the MCU can dissipate up to 60 mW - well within UQFN limits provided EP is soldered.
Place a 100 nF decoupling capacitor within 3 mm of each VDD pin and a bulk 1-10 uF capacitor near the MCU. For ADC accuracy, add a small ferrite bead or 10 ohm resistor between the digital VDD and analog AVDD to isolate switching noise. Keep crystal traces (if used) short and surrounded by ground copper, and route the MCLR line with a 10 kohm pull-up to VDD. Decoupling must be placed before any high-speed traces cross the MCU pins to avoid coupling noise into ADC inputs.
Do not leave unused I/O pins floating - configure them as outputs or inputs with internal weak pull-ups. Unused pins left floating can draw tens of microamps each and may oscillate, injecting noise into adjacent analog inputs. For Sleep-mode designs, verify that all peripherals are properly disabled in software before entering Sleep; an enabled ADC peripheral left running can dominate the sleep current. When migrating code between 15355/15375/15376, validate that vector table addresses and config-word settings are regenerated for the target device - header files alone do not protect against config mismatches.
When using the SPI or I2C peripherals to drive external devices, keep trace lengths under 50 mm and add 22-33 ohm series resistors on clock lines to dampen reflections. For EUSART-based RS-485 buses, add TVS diodes at the bus pins and 120 ohm termination resistors at the cable ends. The CLC outputs can toggle up to the system clock rate, so place them away from sensitive analog inputs to prevent capacitive coupling. If using the CWG for MOSFET gate driving, keep the gate-drive traces short and use a ground return path directly under the gate trace to minimize loop inductance.
