PIC16LF1825-E/P Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data RAM, and peripherals around an 8-bit data path. The PIC16LF1825 belongs to the PIC16 enhanced mid-range architecture family, which sits within the broader category of PIC microcontrollers, which themselves are RISC microcontrollers, which are a subset of microcontrollers, which are integrated circuits designed for embedded control. This taxonomy matters because it places the part in the same family tree as PIC18 and dsPIC devices, all sharing the Microchip MPLAB X toolchain.
Key features include 14KB (8K x 14) Flash program memory, 1KB RAM, 256 bytes EEPROM, 32MHz internal oscillator, and 12 enhanced I/O pins. The device operates from 1.8V to 3.6V (LF variant) and supports the nanoWatt XLP sleep modes with currents below 30 nA in sleep with Watchdog Timer enabled. Integrated peripherals include a 10-bit ADC with up to 8 channels, two comparators, PWM modules, EUSART, I2C/SPI, and mTouch capacitive sensing for touch-button user interfaces.
The PIC16LF1825-E/P uses an enhanced mid-range 14-bit instruction set with 200ns instruction execution at 32MHz, providing 8 MIPS throughput. Its wide operating voltage range (1.8V-3.6V) and ultra-low-power architecture suit battery-operated applications. The 14-pin PDIP package supports hand prototyping, breadboard evaluation, and through-hole assembly where SMT is not desired.
Typical applications include battery-powered sensor nodes, capacitive touch-button interfaces, low-power IoT end nodes, consumer electronics remote controls, and small motor control loops. The integrated mTouch peripheral allows designers to add up to 8 touch sensors without external components, while the LF (low-voltage) variant enables direct Li-ion or 2x AA battery operation.
When designing with this device, ensure decoupling capacitors are placed close to VDD, follow Microchip AN1171 (Low-Power Design Guide) for sleep-mode optimization, and use ICD 3 or PICkit 3 for in-circuit debugging through the ICSP interface. The 14-pin PDIP is breadboard-friendly for prototyping.

The PIC16LF1825-E/P's small 14-pin PDIP form factor, low-voltage operation, and integrated peripherals suit TV/STREAMING remote controls. The 32MHz CPU runs IR or BLE stack protocols; the 10-bit ADC reads battery voltage; and the EUSART interfaces with BLE chipsets. The sub-30nA sleep current extends battery life over the shelf life of the device, and the extended temperature range (-40C to +125C) supports storage in hot vehicles or cold garages.
Recommended
Small Motor Control (DC, Stepper, Fan)
The PIC16LF1825-E/P integrates ECCP (Enhanced Capture/Compare/PWM) modules and 2 comparators for closed-loop control of small DC fans, pumps, and stepper motors. The 32MHz CPU runs PID loops at 100Hz+, while the 14KB Flash stores lookup tables and startup routines. The 1.8V-3.6V range covers battery-powered robotics, and the extended temperature range suits under-hood automotive and outdoor applications where motor heat is a concern.

Industrial 4-20mA Sensor Transmitters
The PIC16LF1825-E/P's 10-bit ADC, 1.8V-3.6V range, and extended -40C to +125C temperature operation suit 2-wire 4-20mA loop-powered industrial sensor transmitters. The mTouch capacitive sensing provides button-free calibration interfaces; the I2C peripheral reads external digital sensors; and the PWM output drives the current loop controller. The 14KB Flash holds linearization tables for thermocouples and RTDs without external memory.
Recommended
Wearable Health and Fitness Bands
The PIC16LF1825-E/P's nanoWatt XLP sleep currents below 30nA and 1.8V-3.6V coin-cell operation fit disposable and rechargeable wearable bands. The 32MHz CPU handles optical heart-rate (PPG) and accelerometer processing via I2C, while the mTouch peripheral supports capacitive side-button taps. The 12 enhanced I/O allow multiple LED indicators, vibration motor control, and battery charging. Small code size and ICSP-compatible debugging accelerate development.
Recommended
Smart Agriculture Soil and Climate Nodes
The PIC16LF1825-E/P operates from solar-charged Li-ion cells at 1.8V-3.6V with sub-30nA sleep, suiting remote outdoor agriculture deployments where battery replacement is costly. The 10-bit ADC reads soil moisture, temperature, and light sensors; the EUSART connects to LoRaWAN or NB-IoT modems; and the LF voltage range eliminates the need for a separate LDO. The extended -40C to +125C range withstands direct-sun and winter conditions in greenhouses and open fields.

Design Notes
For battery applications, follow Microchip AN1171 (Low-Power Design Guide) to optimize sleep-mode current. Configure unused peripherals to off-state using CMCON, CCP1CON, and CVRCON registers. Place the Watchdog Timer in 'sleep-off, WDT-off' mode for the lowest standby current (sub-13nA), and use the INTOSC 31kHz LF clock for timer-based wake-up. Add a 100nF ceramic decoupling capacitor close to VDD (pin 1) and a 10uF bulk capacitor at the battery terminals.
Even in a 14-pin PDIP through-hole layout, place a 100nF ceramic decoupling capacitor within 5mm of pin 1 (VDD) and a 10uF bulk capacitor at the supply input. Keep the ICSP traces (RA5/ICSPCLK and RA3/MCLR) short and free of series resistance to allow reliable in-circuit debugging. For mTouch capacitive sensing, route the touch electrode traces with adequate ground shielding on adjacent layers to prevent false triggers.
Do not skip the MCLR pull-up resistor (typically 10kOhm to VDD) - a floating MCLR pin can cause spurious resets. The CONFIG register must explicitly disable the Watchdog Timer if unused, or enable WDT in the Sleep-disabled mode. When using the internal 32MHz oscillator, allow at least 2ms startup time before code execution - the OST (Oscillator Start-up Timer) bit handles this automatically. The LF variant (PIC16LF1825) must not be powered above 3.6V; the F variant supports 5.5V.
