PIC16F1825-E/JQ Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (typically Flash), data RAM, and a configurable peripheral set into one package. PIC microcontrollers use a RISC-based Harvard architecture with separate program and data buses, executed through a small instruction set that simplifies compiler and assembly-level design. Within the MCU taxonomy, the PIC16F family sits as an enhanced mid-range option bridging legacy baseline PIC12/PIC16 and the higher-pin PIC18/dsPIC families, optimized for low-power and mixed-signal embedded applications. The -E/JQ suffix denotes the industrial/extended temperature grade and the UQFN-16 (4x4) package.
Key differentiating features include 49 base instructions with 16 stack levels, self-read/write Flash, an integrated temperature indicator, mTouch capacitive touch support, and sleep currents below 100 nA typical in XLP mode. The wide 1.8V-5.5V operating range with internal voltage reference and on-chip debug logic allows single-supply ICSP programming and PICkit 3 / MPLAB ICD 3 toolchain compatibility.
Architecturally, the device uses a 14-bit instruction word, 8-bit data path, and an internal 32MHz oscillator that eliminates the need for an external crystal in many designs. Internal PLLs and configurable clock dividers allow fine-grained power/performance trade-offs. The integrated capacitive sensing module reduces BOM cost by replacing mechanical buttons with touch pads routed directly to I/O pins.
Typical applications include battery-powered IoT sensor nodes, consumer human-interface devices with capacitive touch, automotive interior accessory control, small home appliances with LCD/LED feedback, and low-cost industrial sensor transmitters. The combination of low sleep current, ample Flash/RAM, and small footprint makes it well suited for cost-sensitive space-constrained designs.
When designing with the PIC16F1825-E/JQ, ensure decoupling capacitors (100nF + 10uF) are placed close to VDD/VSS pins. For capacitive touch, follow Microchip AN1258 layout guidance to avoid noise coupling. The 16-pin UQFN requires careful PCB land pattern design and a thermal pad for reliable reflow.

Typical Applications
PIC16F1825-E/JQ is suitable for 7 applications: Battery-Powered IoT Sensor Node, Capacitive Touch User Interface, Automotive Interior Accessory Control, Small Home Appliance Control Board, Industrial Sensor Transmitter, LED Lighting Control with PWM Dimming, Consumer Remote Control with Touch Buttons.
Battery-Powered IoT Sensor Node
The PIC16F1825-E/JQ is well suited for battery-powered IoT sensor nodes thanks to its NanoWatt XLP core with sub-100nA sleep current, 32MHz internal oscillator that eliminates external crystals, and 1.8V-5.5V supply range that supports direct connection to single-cell lithium or two-AA alkaline batteries. The integrated 12-channel 10-bit ADC reads temperature, humidity, and battery voltage with no external signal chain. At typical duty-cycled operation (1 wake-up per second with 10ms active time), battery life extends beyond 5 years on a single CR2032. The E grade (-40 to +125 C) supports outdoor and industrial sensor deployments where temperature swings are common.
Recommended
Capacitive Touch User Interface
The PIC16F1825-E/JQ integrates Microchip's mTouch capacitive-sensing module (CTMU based), enabling touch buttons, sliders, and proximity sensors with no external touch controller IC. Up to 12 capacitive channels can be scanned using standard PCB pads as sensors, reducing BOM cost and PCB area for consumer appliances, lighting controls, and personal-care products. The 32MHz CPU executes touch-scanning firmware in microseconds, leaving ample cycles for LED PWM and UART communication. Following Microchip application note AN1258 layout guidelines, guard traces and uniform sensor pad geometry minimize false triggers in noisy environments.
Recommended
Automotive Interior Accessory Control
The PIC16F1825-E/JQ's E grade temperature range of -40 C to +125 C makes it suitable for non-safety automotive interior applications such as ambient lighting controllers, USB charging ports, seat heating controls, and rear-seat entertainment interfaces. The 32MHz core handles CAN-style serial protocols, PWM dimming, and button matrix scanning concurrently. While the standard PIC16F1825 is not AEC-Q100 qualified, its E temperature grade and automotive-grade production processes have made it a common choice in cost-sensitive interior modules. For safety-critical applications, Microchip's AEC-Q100 PIC16F variants are recommended.
Recommended
Small Home Appliance Control Board

The 14KB Flash comfortably stores state machines, lookup tables for temperature curves, and LCD driver routines. The integrated 32MHz oscillator reduces BOM by eliminating external crystals. The UART and I2C peripherals connect to WiFi or BLE modules for IoT-connected appliances, while the small UQFN-16 (4x4) footprint fits into tight mechanical enclosures.
Recommended
Industrial Sensor Transmitter
The PIC16F1825-E/JQ operates reliably in industrial environments thanks to its -40 C to +125 C extended temperature range, 5.5V supply tolerance for 24V-bus-derived rails (via regulator), and robust PIC architecture with high noise immunity. Industrial sensor transmitters use the ADC to digitize 4-20mA or 0-10V signals from field sensors, then output scaled values over RS-485, UART, or I2C. The 14KB Flash accommodates calibration tables and linearization routines. Engineers value the PIC16F1825's predictable interrupt latency for deterministic sampling loops.
Recommended
LED Lighting Control with PWM Dimming
The PIC16F1825-E/JQ drives LED lighting modules via its CCP/ECCP PWM peripherals, supporting smooth dimming and color mixing in RGBW fixtures. The 10-bit PWM resolution produces 1024 brightness steps, sufficient for high-quality fade transitions. The EUSART accepts DMX512 or proprietary commands from a master controller, while the internal 32MHz oscillator provides accurate PWM frequency. Sleep current below 100nA makes the part suitable for always-listening remote controls that wake on interrupt. The UQFN-16 (4x4) package fits into miniature bulb-form-factor LED controllers.
Recommended
Consumer Remote Control with Touch Buttons
The PIC16F1825-E/JQ suits TV remote controls, smart-home keypads, and wearable remote controllers where its mTouch capacitive-sensing module replaces mechanical buttons for a sleek sealed-surface design. Sub-100nA sleep current extends battery life beyond 2 years on a single CR2032. The internal 32MHz oscillator handles IR carrier generation for consumer remote protocols (RC5, NEC, SIRC) with no external resonator. The 1KB RAM supports learned-button databases and protocol macros for universal remote applications.

Design Notes
Place a 100nF decoupling capacitor as close as possible to the VDD pin (pin 16) and a bulk 10uF capacitor on the same power rail within 10mm. For battery applications, the XLP sleep mode draws sub-100nA typical - verify by measuring actual current on hardware because peripheral activation (ADC, timers, WDT) can multiply sleep current by 10x to 100x. Disable unused peripherals via the PMDx registers to achieve the lowest standby current. For USB or wireless module power, gate the auxiliary supply through a MOSFET controlled by an I/O pin to fully power-down peripherals during deep sleep.
The PIC16F1825-E/JQ's UQFN-16 package has a small thermal pad on the bottom that must be soldered to a copper pour on the PCB for reliable reflow and improved thermal dissipation. The exposed pad should connect to VSS or float depending on the application note guidance. Estimated: at 32MHz full-speed operation from 3.3V supply, the device dissipates approximately 8-10mW, well within the UQFN-16's thermal envelope; however, industrial environments with high ambient temperature require the E grade's -40 to +125 C rating. Verify reflow profile matches JEDEC J-STD-020 for MSL1 UQFN packages.
The UQFN-16 (4x4mm) package has a 0.5mm pitch and requires careful PCB land pattern design per Microchip package drawing specifications. For capacitive touch applications, follow Microchip application note AN1258 layout guidance: use guard traces around touch pads, maintain uniform sensor pad geometry, and keep digital signals away from analog/touch traces. Avoid running high-frequency switching signals (PWM, UART) parallel to touch-sensor traces. Place the IC close to touch pads to minimize trace capacitance and noise coupling. A 4-layer PCB with dedicated ground plane is recommended for designs with sensitive analog measurements.
Do not exceed the absolute maximum VDD of 6.5V or operate below 1.8V (the Brown-Out Reset threshold may trigger). The MCLR pin (shared with RA3) requires a careful decision: configure as reset for easier programming, or as GPIO to free up an I/O pin. For ICSP programming, ensure the ICSPDAT and ICSPCLK lines are accessible and not loaded down by external circuits. When migrating from PIC16F1825 to PIC16F15325, review peripheral register map differences - the migration guide lists specific bit-field changes in ADC, PWM, and EUSART modules that may require firmware updates.
Compliance Information
