PIC16LF15386-I/PT Présentation
An 8-bit PIC microcontroller (MCU) is a single-chip computer built on a Harvard-architecture RISC core that fetches instructions from Flash memory while accessing data from a separate SRAM bus, executing one instruction per clock cycle (except branches). PIC16F-family devices sit in Microchip's mid-range portfolio, occupying the slot between small 6/8/14-pin baseline PIC10/12/16F parts and the high-performance PIC18F/PIC24F families. They are widely used in battery-powered and space-constrained designs where predictable interrupt latency and deterministic peripheral behaviour outweigh raw CPU throughput. The PIC16LF15386 specifically belongs to the 'low-voltage F' (LF) subfamily, which extends the supply range down to 1.8V while preserving full peripheral functionality.
Key features include 28KB Flash, 2KB RAM, 4 PWM channels, 2 EUSART modules, SPI/I2C interfaces, a 10-bit ADC with DAC, a comparator, a Complementary Waveform Generator (CWG), and 4 Configurable Logic Cells (CLC). The 32MHz internal oscillator supports instruction cycle times down to 125 ns, and the XLP technology delivers sleep currents as low as a few nanoamperies with RTC retention. The device operates across 1.8V to 3.6V, making it compatible with single-cell Li-ion or two-cell alkaline battery rails.
The 48-TQFP (7x7 mm) package offers an exposed thermal pad and supports up to 44 programmable I/O pins. Its peripheral set enables direct interfacing with sensors, LED drivers, and human-interface components without external logic. Hardware CIPs - including the CLC, CWG, and signal-routing fabric - allow complex timing and logic functions to operate independently of the CPU, freeing the core to remain in sleep for maximum energy efficiency.
Typical applications include IoT sensor nodes, low-power wireless modules, consumer white goods, battery-powered medical devices, and industrial sensor interfaces. The wide peripheral integration suits designs that require multiple communication buses, PWM-driven actuators, and analog front-ends on a single 8-bit chip.
When designing with this part, confirm that the 48-TQFP land pattern matches the PCB footprint. Note that the LF subfamily is limited to 3.6V maximum; designs requiring 5V operation should select the PIC16F15386 variant instead. Always check the MPLAB X IDE compatibility and the latest device errata before committing to volume production.

Applications typiques
PIC16LF15386-I/PT convient pour 7 applications: Battery-Powered IoT Sensor Nodes, Consumer White Goods and HMI, Portable Medical Devices, Industrial Sensor Interfaces, LED Lighting and Signage Controllers, Automotive Body and Comfort Modules (Sub-System), Home Automation and Smart Home Hubs.
Battery-Powered IoT Sensor Nodes
The PIC16LF15386-I/PT suits battery-powered IoT sensor nodes where XLP nanoamp sleep currents extend service life and the 1.8V-3.6V range supports single-cell Li-ion or 2x alkaline cells. The 28KB Flash accommodates OTA update stubs plus application logic for temperature, humidity, or motion sensors, while 2KB RAM buffers sensor reads. Core Independent Peripherals (CIPs) such as the CLC and CWG let timing-critical signal conditioning run while the CPU sleeps, achieving years of battery life. Two EUSARTs and SPI/I2C interface radios (LoRa, BLE, sub-GHz) without external logic.
Recommandé
Consumer White Goods and HMI
In washing machines, dishwashers, microwave ovens, and other white goods, the PIC16LF15386-I/PT drives segment LCDs or LED indicators, scans capacitive touch via the CLC and comparator peripherals, and runs brushless DC motor control through the 4 PWM channels and the Complementary Waveform Generator (CWG). The 32MHz core and 28KB Flash accommodate user-interface state machines plus safety diagnostics. Hardware CIPs reduce CPU load, allowing low-cost BOM while keeping firmware simple and certifiable for IEC 60335 household safety standards.
Recommandé
Portable Medical Devices
The PIC16LF15386-I/PT fits portable medical devices such as blood-pressure monitors, glucose meters, and pulse oximeters where the 1.8V-3.6V range aligns with battery rails and the low sleep current extends runtime between charges. The 10-bit ADC and on-chip DAC interface analog front-ends for sensor conditioning, while the 2 EUSARTs communicate with wireless modules (BLE) or wired accessories. The wide industrial temperature grade (-40C to +85C) supports controlled storage and patient environments with predictable peripheral behaviour under intermittent loads.
Recommandé
Industrial Sensor Interfaces
Industrial 4-20 mA loops, RTD/thermocouple conditioning, and digital sensor hubs benefit from the PIC16LF15386-I/PT's deterministic interrupt handling and Core Independent Peripherals. The PIC16LF15386-I/PT operates from 1.8V to 3.6V; for industrial bus nodes requiring 5V I/O, the drop-in compatible PIC16F15386-I/PT variant is preferred. The 32MHz core and 4 PWM channels support motor-position feedback loops, while EUSART modules bridge Modbus RTU or RS-485 networks. The 48-TQFP footprint and industrial temperature grade suit harsh factory environments with extended field-life expectations.
Recommandé
LED Lighting and Signage Controllers
The PIC16LF15386-I/PT drives addressable RGB LED strips and DMX512 lighting controllers through its 4 PWM channels and the Complementary Waveform Generator (CWG). With 28KB Flash, designers can store color presets, fade curves, and DMX personality profiles locally. The 32MHz instruction rate sustains smooth dimming transitions, and the 1.8V-3.6V range suits USB-powered decorative fixtures and battery-backup emergency signage where the CLC peripherals implement hardware safety interlocks independent of CPU latency.
Recommandé
Automotive Body and Comfort Modules (Sub-System)
While the PIC16LF15386-I/PT is not AEC-Q100 qualified itself, the identical-footprint PIC16F15386-I/PT variant and PIC16F19186-I/PT are common in non-safety automotive body controllers such as interior lighting, mirror adjust, and seat-position modules. Designers prototype with the LF part on the bench, then qualify the F variant for volume. The 32MHz core and 4 PWM channels drive small BLDC or stepper motors; the CLC peripherals handle logic interlocks deterministically; and the 28KB Flash holds lookup tables for position memory across multiple drivers and profiles.
Recommandé
Home Automation and Smart Home Hubs
In home automation hubs, the PIC16LF15386-I/PT acts as a sensor-edge processor aggregating data from PIR motion detectors, door/window contacts, and environmental sensors before forwarding via EUSART/SPI to a higher-tier gateway. The 28KB Flash accommodates Z-Wave/Zigbee/Wi-Fi stack stubs, and the on-board RTC with XLP enables duty-cycled wake/sleep schemes that stretch coin-cell life beyond 5 years. The 2KB RAM buffers sensor bursts during interrupts, while the CLC peripherals debounce mechanical switch inputs without CPU intervention.

Notes de conception
Estimated: at 32MHz active, VDD=3.3V, the PIC16LF15386-I/PT draws approximately 5-7 mA depending on peripheral activity. Sleep current with RTC and retention is specified in the low nanoampere range (XLP mode). For battery-life calculations, integrate the active-mode current with duty cycle. Decouple VDD/AVDD pairs with 100nF ceramic capacitors placed within 5 mm of each pin, and add a bulk 10uF tantalum or ceramic at the supply entry point.
The 48-TQFP (7x7 mm) package has a theta_JA of approximately 70-80 C/W on a standard 4-layer JEDEC test board. At full active load the device dissipates well under 100 mW, so thermal management is rarely an issue. Estimated junction temperature rise at 25C ambient is below 5C. For sealed enclosures or high-ambient industrial settings, ensure at least 1 square inch of copper ground pour is connected to the exposed pad.
Route ICSP signals (RB6/ICSPCLK, RB7/ICSPDAT, MCLR/VPP) with short, direct traces to a 5-pin header; keep these traces away from high-current switching nodes. Place the 32.768 kHz crystal (if used) close to SOSCO/SOSCI with guard traces to ground. The analog supply pins AVDD/AVSS should be star-routed from the digital VDD/VSS pair through a ferrite bead to minimise ADC reference noise.
Do not exceed 3.6V on VDD - the LF subfamily lacks 5V tolerance. The MCLR pin should be tied to VDD through a 10k resistor with a 100nF capacitor for ICSP programming; floating MCLR can cause spurious resets. Configuration word settings (FOSC, WDTE, BOREN, LVP) must be set before code is committed; review MPLAB X default settings against your application's reset and oscillator requirements.
The 32MHz HFINTOSC provides 1% accuracy after factory calibration, sufficient for UART baud rates up to 115200 with adequate margin. For applications requiring tighter frequency accuracy (CAN, USB reference, IEEE 1588 timing), switch to an external crystal via the FOSC configuration word. The CLC peripherals can implement hardware signal debouncing and edge detection without CPU load, freeing firmware from tight polling loops.
