PIC16LF15325-I/P Overview
An 8-bit microcontroller is a single-chip computer that combines an 8-bit CPU core, program memory, data memory, I/O peripherals, and often communication interfaces into one device. Within the broader taxonomy, MCUs sit below microprocessors in complexity and above discrete logic in integration; 8-bit MCUs specifically trade raw throughput for deterministic interrupt latency, low power consumption, and ease of programming, making them ideal for cost-sensitive, latency-critical embedded control tasks such as sensor reading, simple actuator driving, and protocol bridging.
Key specifications of the PIC16LF15325-I/P include 14KB (8K x 14 words) flash with self-programmability, 1KB RAM, 256 bytes of EEPROM data, four 10-bit PWM channels, a 10-bit ADC, a 5-bit DAC, two comparators, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), and two EUSART/SPI/I2C interfaces. Core-Independent Peripherals (CIPs) handle tasks in hardware without CPU intervention, freeing the core for sleep.
Architecturally the device uses a 32 MHz internal oscillator and an enhanced mid-range 16-bit instruction set, with instruction-cycle interruptible features and a hardware multiplier. XLP technology enables nanoWatt sleep currents as low as 30 nA in Retention mode, allowing years of operation from a coin cell.
Typical applications include IoT sensor nodes, low-power wireless remote controls, consumer electronics, HVAC fan/thermostat control, battery-powered medical monitors, and home appliance user interfaces. Programmatic wake-on-touch and wake-on-I/O pin changes extend battery life further.
When designing with this MCU, reserve adequate decoupling (100 nF + 1 µF) within 5 mm of VDD, and consider the ICD 4 / PICkit 5 in-circuit debugger footprint if programming is required in-circuit. The 14-pin PDIP variant is footprint-compatible with the PIC16F15325-I/P, providing a 5V-tolerance upgrade path without board rework.

Typical Applications
PIC16LF15325-I/P is suitable for 8 applications: Battery-Powered IoT Sensor Node, Consumer Remote Control with EUSART/Wake-on-IR, Industrial Push-Button Fan or Motor Control, Home Appliance User Interface Board, Medical Wearable / Portable Health Monitor, Automotive LIN Slave Node, HVAC Thermostat Control Module, Low-Power Wireless Sensor Transmitter.
Battery-Powered IoT Sensor Node
The PIC16LF15325-I/P fits battery-powered IoT sensor nodes because of its 30 nA XLP Retention sleep current and 1.8 V to 3.6 V operating range directly compatible with a CR2032 coin cell. Integrated CLC and CWG peripherals let the MCU wake on a sensor interrupt, run an ADC conversion on the dedicated 10-bit ADC, and return to sleep without CPU intervention - a critical feature for years of battery life. Pin 2 (RA0) typically accepts an analog input from a temperature or humidity sensor while pin 11 (RB7) drives a low-power radio sleep/wake control, matching the 14-pin PDIP exposed package.
Recommended
Consumer Remote Control with EUSART/Wake-on-IR
The PIC16LF15325-I/P suits consumer IR/Sub-GHz remote controls because its LF silicon draws as little as 50 nA in Sleep with Wake-on-I/O-change, and the 32 MHz core can run a full IR or Sub-GHz protocol stack at low duty cycle. Four PWM channels plus CWG allow haptic feedback or LED backlighting, and the 14-pin PDIP socket enables rapid hand-solder prototyping during development. Pin 13 (RB6) is typically the EUSART1 TX output to the radio module while pin 4 (RA3/MCLR) doubles as the wake source on button press.
Recommended
Industrial Push-Button Fan or Motor Control
The PIC16LF15325-I/P fits industrial low-voltage fan or motor control boards because it pairs four 10-bit PWM outputs with the Complementary Waveform Generator (CWG) for half-bridge/Class-D switching stages, while two on-chip comparators handle back-EMF sensing and fault shutdown. The 14-pin PDIP package is mechanically robust for enclosed fan tops or appliance boards, and 1.8 V to 3.6 V operation simplifies single-rail designs from 2-cell alkaline or 1-cell Li-coin sources. Peripherals run independently of the core through CIPs, eliminating CPU jitter in control loops.
Recommended
Home Appliance User Interface Board
The PIC16LF15325-I/P drives appliance front panels because it integrates the 14-pin PDIP ease of through-hole assembly, four PWM channels for LED backlighting, MSSP I2C for capacitive-touch I/O expanders, and EUSART for the appliance bus. NanoWatt XLP sleep mode prevents standby power consumption that increasingly drives regulatory compliance for home appliances. The MCU also handles button matrix decoding via CLC hardware without waking the CPU on every key event.
Recommended
Medical Wearable / Portable Health Monitor
The PIC16LF15325-I/P is appropriate for portable medical monitors such as pill-bottle reminders, fall detectors, or wearable pulse sensors because its LF variant targets the 3.6 V upper limit used by lithium coin cells and XLP sleep currents as low as 30 nA extend operational life to a year or more. On-chip ADC, 5-bit DAC, and dual comparators enable signal acquisition from ECG/PPG photodiodes or thermistor bridges, while 14 KB flash accommodates firmware for filter pipelines and wireless hand-off. Industrial -40 to +85 °C operating range suits most clinic and home environments per the data sheet.
Recommended
Automotive LIN Slave Node
The PIC16LF15325-I/P works as a low-cost LIN slave node in body-electronics applications because the two on-chip EUSART peripherals both include LIN-protocol hardware (auto-baud detection and break generation), and the 5V-tolerant on selected pins covers 12 V battery transients when paired with an external MCP2017 transceiver. Industrial temperature grade (-40 to +85 °C) handles under-dash environments while the 14-pin PDIP package suits through-hole automotive PCB tooling. Note: the part is not AEC-Q100 qualified - choose the PIC16F15325 equivalent automotive derivative where formal qualification is required.
Recommended
HVAC Thermostat Control Module
The PIC16LF15325-I/P fits HVAC thermostat controls because the LF silicon and XLP architecture handle years of operation on common AA or 2xAA battery backs, the 10-bit ADC supports two-wire analog temperature-sensor resistance bridges, and the four PWM channels drive HVAC damper stepper or triac-firing circuitry via optoisolators. The 14-pin PDIP package is well-suited to wall-mount thermostat PCB assemblies with through-hole serviceability. The CLC peripheral combines hysteresis logic for bang-bang temperature control without CPU overhead.
Recommended
Low-Power Wireless Sensor Transmitter
The PIC16LF15325-I/P works as the host MCU for Sub-GHz or BLE sensor transmitters because its EUSART drives a UART interface directly to a radio module while sleeping at 30 nA idle. The integrated CWG and PWM can produce tone-pattern modulations for low-cost ASK/OOK transmitters without external circuitry, and the 14-pin PDIP socket aids bench-top RF tuning during development. With Retention mode and on-chip peripherals keeping the core off until needed, the part regularly achieves 5-10 years of life on a single CR2032 cell.

Key Differentiators
- Core-independent peripherals (CLC, CWG) operate without CPU wake-up (vs Microchip PIC16F887)
- XLP nanoWatt sleep down to 30 nA in Retention mode (vs Microchip PIC18F family at same clock)
- Dual EUSART with LIN support and two MSSP (I2C/SPI) (vs PIC16LF1825)
Design Notes
Decouple VDD with a 100 nF Y5R/X7R ceramic capacitor placed within 5 mm of pin 1 (VDD) and a 1 µF ceramic bulk capacitor on the same supply trace; for ultra-low-sleep designs add a 1 µF hold capacitor to the MCLR/VPP pin to ensure brown-out-free operation. The LF silicon targets 1.8 V to 3.6 V, so plan a 3.3 V LDO such as MCP1700 or MCP1755 upstream and not a 5 V rail. Estimated: at 30 nA Retention sleep + periodic 1 ms wake currents under 1 mA, average system draw stays under 5 µA on a CR2032 cell.
Do not connect any signal to the MCLR/VPP pin without a 10 kΩ pull-up and a 100 nF damping capacitor to VSS, since MCLR doubles as the high-voltage programming entry. The 14-pin PDIP socket respects ICSP pin assignment on RB6/ICSPCLK and RB7/ICSPDAT, so leave a 4-pin header pad pattern available on the PCB even if you are not currently using in-circuit programming. Avoid connecting analog sources to digital I/O-only pins (RA6/RA7 etc.) when those pins are missing.
Route the analog VDD/VSS pair with wide traces or a ground plane and keep high-speed digital traces away from the analog ADC input pins (RA0 to RA3 plus RA4, RA5). Place the ICSP header at the PCB edge to enable plug-and-programming with PICkit 5 and MPLAB ICD 4. The 14-pin PDIP pinout also fits on a 14-pin SOIC/SSOP/TSSOP footprint if you migrate to the I/SL or I/ST siblings later - plan a compatible PCB land pattern from the start for cost reduction.
Compliance Information
Per Microchip product page, the -I/P industrial grade covers -40 °C to +85 °C. AEC-Q100 qualification is not available on this specific grade; for automotive use the PIC16F15325 family offers higher temperature grades.
