PIC16LF15385T-I/PT Overview
An 8-bit microcontroller is a single-chip computer that processes data 8 bits at a time using a Harvard or von Neumann architecture and is most commonly deployed as the central control element in embedded products. Microcontrollers fall within the broader hierarchy: microcontroller -> embedded processor -> semiconductor device. PIC microcontrollers use a RISC instruction set with a small, fixed instruction width optimized for deterministic interrupt response and low active current, making them ubiquitous in cost-sensitive consumer and industrial designs.
The PIC16LF15385T-I/PT stands out for its Core Independent Peripherals (CIPs) such as CLC, CWG, and NCO that execute logic, waveform, and frequency synthesis without CPU intervention, freeing the core for application code. XLP technology delivers nanoWatt XLP sleep currents below 65 nA typical in sleep with retention, and an active current of approximately 5 µA at 32 kHz / 1.8 V. The 48-pin TQFP provides 43 I/O pins and broad analog integration in a compact 7 mm × 7 mm footprint.
Typical applications include low-power IoT sensor nodes, battery-operated home automation devices, industrial control front-ends, sensor signal conditioning, and human-machine interface (HMI) controllers. The 4xCLC and CWG blocks make it well suited for digital power and motor control signal generation in small appliances.
When designing with this device, place the 0.1 µF VDD decoupling capacitor within 2 mm of each VDD pin and use a 10 µF bulk capacitor near the IC. Configure unused I/O as outputs low to minimize sleep current, and verify the WDT postscaler selection against your worst-case interrupt latency requirement.

Typical Applications
PIC16LF15385T-I/PT is suitable for 7 applications: Battery-Operated IoT Sensor Node, Industrial Sensor Signal Conditioning, Home Automation HMI Controller, Low-Power Motor Control (Small Fan/Pump), Portable Medical Monitoring Device, Automotive Body Electronics Sub-Controller, Smart Energy Meter Edge Node.
Battery-Operated IoT Sensor Node
The PIC16LF15385T-I/PT suits battery-powered IoT sensor nodes because of its 1.8–3.6 V XLP supply, ~65 nA typical sleep current, and 14 KB Flash supporting BLE/Zigbee/LoRaWAN lower-stack firmware. The 10-bit ADC interfaces directly to analog sensors (temperature, gas, light), while the EUSART communicates with a UART-attached radio module. The four CLCs allow event-driven wake-ups from sensor threshold crossings without waking the CPU, reducing average current draw to single-digit microamps and enabling multi-year coin-cell operation.
Recommended
Industrial Sensor Signal Conditioning
The PIC16LF15385T-I/PT integrates two comparators, a 5-bit DAC, and a 10-bit ADC that handle direct sensor conditioning for industrial 4–20 mA loops, RTDs, and bridge sensors. The CLCs implement digital filtering and hysteresis to suppress noise from motor-driven environments. Industrial-grade -40 °C to +85 °C operation and Microchip's product longevity commitment through 2033 make this part appropriate for long-life factory automation and process control front-ends.
Recommended
Home Automation HMI Controller
The PIC16LF15385T-I/PT powers cost-effective HMI sub-controllers for smart thermostats, appliance keypads, and LED lighting controls. The four 10-bit PWMs drive LED dimmers and motor speed signals, while the two EUSART channels interface to a host MCU or wireless module. The 43 I/O pins accommodate matrix keypads, rotary encoders, and segment LCD bias generation. Per Microchip datasheet DS40001894D, the CLCs can implement rotary encoder quadrature decoding in hardware, offloading the CPU for smoother UI response.
Recommended
Low-Power Motor Control (Small Fan/Pump)
The PIC16LF15385T-I/PT drives small brushless DC fans or pumps using the Complementary Waveform Generator (CWG) for hardware dead-band generation. The 4xCLC and CWG blocks cooperate to produce center-aligned PWM with automatic fault shutoff, eliminating software jitter. With XLP sleep current below 65 nA, battery- or solar-powered pumps can idle indefinitely between activation cycles. Pinout-compatible alternatives in the same family scale to higher-current needs without firmware or PCB redesign.
Recommended
Portable Medical Monitoring Device
The PIC16LF15385T-I/PT fits portable medical peripherals such as pulse oximeters, blood pressure cuffs, and portable spirometers where XLP nanoWatt sleep extends battery life. The 10-bit ADC captures sensor waveforms, and the two comparators implement threshold detection for alarm conditions. The CLCs deliver glitch-free hardware FSMs for sensor sequencing, reducing software overhead for FDA/IEC 62304-validated firmware. Industrial-grade operating temperature supports clinical and home-care environments.
Recommended
Automotive Body Electronics Sub-Controller
The PIC16LF15385T-I/PT serves as a sub-controller in non-safety automotive body electronics such as interior lighting, seat controllers, and accessory multiplexers. Two EUSART channels support LIN-bus communication via an external transceiver, while the PWMs drive LED clusters and small motors. The 48-pin TQFP delivers 43 GPIO for matrix lighting and switch scanning. For AEC-Q100-qualified automotive applications, choose the PIC16F15385-E/PT extended-temperature variant instead of the -I grade.
Recommended
Smart Energy Meter Edge Node
The PIC16LF15385T-I/PT operates as an edge node in smart energy meters, conditioning current/voltage sensor outputs and transmitting data via UART-attached wireless modems. The 14 KB Flash supports IEC 62056 DLMS/COSEM lower-stack helpers, while the CLCs implement pulse-counting for mechanical meter retrofits. Sleep current below 65 nA permits battery backup during power outages. Pinout compatibility with PIC16LF15376T-I/PT enables firmware expansion when more protocol overhead is needed.

- Industrial temperature grade standard (vs PIC16LF15385-E/PT)
Design Notes
Place one 0.1 µF ceramic decoupling capacitor within 2 mm of each VDD/AVDD pin (pins 9, 19, 46) and a single 10 µF bulk capacitor near the IC. Per Microchip datasheet DS40001894D, the analog supply AVDD should be tied to VDD on the PCB even if the ADC is unused, otherwise leakage through ESD structures can elevate ADC offset. Estimate: an XLP sleep node with 65 nA sleep current and 10 ms hourly wake-up yields ~24 µAh annual battery drain, sufficient for CR2032 longevity.
Route the ICSP/Debug pins RB6 and RB7 (pins 17, 18) to a 2x3 0.1" header or Tag-Connect footprint to support MPLAB ICD programming in-circuit. Per Microchip application note TB3035, isolate the ICSP connector with 4.7 kΩ series resistors only if pin-sharing is necessary, otherwise route directly. The 48-pin TQFP pad pitch is 0.5 mm; ensure your PCB fab supports 0.5 mm QFP land pattern with non-solder-mask-defined pads for robust assembly.
Do not leave unused I/O pins floating - configure them as outputs driving low to minimize sleep current. The MCLR pin (RE3) must be pulled high through a 10 kΩ resistor for normal operation; if unused, configure it as a digital input with the internal weak pull-up enabled. Estimated: floating CMOS inputs can draw 1–10 µA each, multiplying quickly across 43 I/O pins and destroying XLP battery-life targets.
Place the external 32.768 kHz crystal within 5 mm of SOSC pins and guard the traces with a ground ring to reduce noise injection into the timer domain. Per Microchip datasheet DS40001894D, when using HFINTOSC at 32 MHz no external crystal is needed, saving BOM cost but at the expense of ±2% frequency accuracy. For UART communications requiring tighter baud-rate tolerance, switch to an external HS crystal or use the 31 kHz LFINTOSC for low-precision timing only.
Compliance Information
RoHS and REACH compliant per Microchip product page. -I industrial grade is not AEC-Q100 qualified; choose -E extended or -Q automotive variants for AEC-Q100 applications.
