PIC16F1825T-I/SL Overview
An 8-bit PIC microcontroller is a Harvard-architecture CMOS device that executes one instruction per internal clock cycle (four oscillator cycles) and is positioned in the Microchip product hierarchy as a PIC16 mid-range core MCU below PIC18/dsPIC and above PIC10/12 baseline parts. The PIC16F1825 belongs to the PIC16F/LF182x family that introduced the enhanced mid-range core and CWG (Complementary Waveform Generator), DSM (Data Signal Modulator), and 1.024 MHz internal HFINTOSC plus 32 kHz LFINTOSC clock sources, which eliminate the external crystal in most cost-sensitive applications.
Key features of the PIC16F1825T-I/SL include 14 KB Flash, 1 KB RAM, 256 bytes EEPROM, 12 digital I/O with interrupt-on-change, 8 channels of 10-bit ADC, two Capture/Compare/PWM (CCP) modules, Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART), SPI and I2C peripherals, mTouch capacitive sensing, and an integrated temperature indicator. Operating voltage is 1.8V to 5.5V with typical active current around 1.5 mA at 4 MHz and nanoWatt XLP sleep currents as low as 20 nA.
Typical applications for the PIC16F1825T-I/SL include consumer appliances, LED lighting controllers, capacitive touch user interfaces, battery-powered sensor nodes, and industrial control modules where small footprint, low power, and integrated peripherals reduce total BOM cost. The wide operating voltage and robust peripheral set also suit remote controls, toys, and small IoT edge nodes. The "T" suffix in the part number indicates tape-and-reel packaging, "I" indicates the -40C to +85C industrial temperature range, and "SL" indicates the 14-pin SOIC package.

Typical Applications
PIC16F1825T-I/SL is suitable for 6 applications: Consumer Appliance Control, Capacitive Touch User Interface, Battery-Powered Sensor Nodes, LED Lighting Controllers, Small Industrial Control Modules, Remote Controls and Toys.
Consumer Appliance Control
The PIC16F1825T-I/SL is well suited for consumer appliance control boards such as microwave ovens, washing machine user interfaces, and induction cooktop keypads because its integrated mTouch capacitive sensing module and 12 GPIO pins directly drive mechanical switches or capacitive touch panels without a dedicated touch controller. The 14 KB Flash fits typical appliance firmware with capacitive touch scanning, sensor conditioning, and relay/motor control algorithms, while the 32 MHz core gives 8 MIPS for fast touch acquisition loops. The 1.8V-5.5V supply range lets the MCU run directly from a rectified mains tap with a small linear regulator, and the XLP nanoWatt sleep currents below 1 uA reduce standby power in ENERGY STAR designs. Industrial -40C to +85C temperature tolerance supports the harsh thermal environments found behind appliance front panels.
Recommended
Capacitive Touch User Interface
For standalone capacitive touch panels such as cooktop sliders, lighting keypads, and smart-switch front panels, the PIC16F1825T-I/SL's mTouch CSM module supports up to 12 touch sensors with hardware-assisted scanning and software-configurable sensitivity. Its 10-bit ADC provides raw capacitance measurements for advanced water-proof or proximity algorithms, while the 14 KB Flash can store sophisticated multi-touch gesture recognition firmware. The 32 MHz instruction rate executes one full touch scan frame in microseconds, reducing latency to a level indistinguishable by users. Low XLP standby currents make it suitable for always-on battery-powered touch remotes, and the industrial temperature range prevents drift in high-heat or outdoor environments.
Recommended
Battery-Powered Sensor Nodes
The PIC16F1825T-I/SL is ideal for wireless sensor nodes and remote battery sensor transmitters thanks to its nanoWatt XLP technology, with sleep currents as low as 20 nA preserving multi-year battery life on a single coin cell. The 1.8V minimum operating voltage extends usable life after the battery has discharged below typical 3V, and the integrated 32 kHz LFINTOSC eliminates the external watch crystal. The 14 KB Flash and 1 KB RAM comfortably handle sensor sampling, MAC protocols, and small over-the-air stacks, while the EUSART and I2C peripherals interface directly with sub-GHz radios, accelerometers, and digital temperature sensors. Robust -40C to +85C operation supports outdoor IoT deployments in uncontrolled thermal environments.
Recommended
LED Lighting Controllers
Architectural and decorative LED drivers benefit from the PIC16F1825T-I/SL's two Enhanced CCP modules, which deliver 10-bit PWM resolution at the 32 MHz clock and support complementary outputs with programmable dead-band for synchronous buck converters. The 14 KB Flash stores DMX-512, DALI, or proprietary wireless lighting protocols, and the EUSART provides the DMX hardware interface with no external UART. The 1.8V-5.5V supply operates directly from a small switching converter, and the XLP sleep current is below the leakage of typical driver circuitry. With up to 12 I/O pins, the MCU can also drive discrete LED drivers, analog dimming references, and addressable strip data lines without auxiliary chips.
Recommended
Small Industrial Control Modules
The PIC16F1825T-I/SL serves compact industrial controllers such as low-cost PLC expansion cards, data loggers, and process sensor transmitters. Its 10-bit ADC reads 4-20 mA loops and bridge sensors, and the EUSART/SPI/I2C stack interfaces with industrial fieldbus transceivers and HMI displays. The 256-byte EEPROM holds non-volatile calibration constants and unit ID values with 1M write cycle endurance, suitable for configuration data over a product's lifetime. The -40C to +85C industrial temperature rating and ESD protection simplify CE/UL industrial certification. The 14-SOIC package is robust for wave-soldered industrial board assembly and easy to hand-prototype during development.
Recommended
Remote Controls and Toys
For infrared remote controls, RC toys, and consumer handheld devices, the PIC16F1825T-I/SL offers low-cost 8-bit performance with sub-microamp standby currents to maximize battery life across shelf and active-use lifetimes. The 14 KB Flash stores complex button matrix, gesture, and bidirectional RF protocols, and the PWM drives IR LEDs or vibration motors directly. The wide 1.8V-5.5V supply range supports 2xAAA through single-cell Li-Ion configurations without boost converters. The integrated mTouch module enables modern touch-button RC designs at no extra component cost, and the small 14-SOIC footprint fits the tightest handheld enclosures. Industrial temperature range tolerates glove-touch and outdoor use.

Key Differentiators
- Integrated mTouch capacitive sensing module (vs PIC16F1575-I/SL)
- Larger program memory than family cost-down variants (vs PIC16F1823T-I/SL and PIC16F1824T-I/SL)
- Same silicon as PIC16F1825-I/SL with T&R packaging (vs PIC16F1825-I/SL)
Design Notes
Estimated: at 32 MHz active from 3.3V, the PIC16F1825T-I/SL draws approximately 5-7 mA active current. For battery applications, switch to the 32 kHz LFINTOSC or sleep mode with 20 nA typical draw to extend life. The mTouch module adds 30-50 uA per active channel; disable unused channels before scanning to minimize peak load. When using the internal FVR for ADC reference, allow at least 25 us settling time after enabling.
Place the 0.1 uF VDD decoupling capacitor within 5 mm of the VDD pin (pin 14) with a wide ground trace to VSS (pin 13). Keep the ICSP programming traces (RA0/RA1 as ICSPCLK/ICSPDAT) accessible with a 6-pin header for production programming. For mTouch designs, route sensor traces in a dedicated copper pour disconnected from VDD, surrounded by a ground guard ring; the datasheet recommends sensor trace width 0.15-0.20 mm and length below 100 mm.
Do not drive MCLR (RA3) low in the application circuit - it is the master clear reset pin. If unused, tie RA3 directly to VDD through a 10 kohm pull-up resistor to enable normal operation, or to VDD directly to disable the reset. The internal weak pull-up on RA3 is too weak for noisy industrial environments; an external 10 kohm resistor is recommended. The "T" suffix in PIC16F1825T-I/SL is mandatory for tape-and-reel compatibility with automated pick-and-place equipment.
