PIC16LF15325-I/JQ Overview
An 8-bit microcontroller (MCU) is a compact processor-on-a-chip that combines a CPU, non-volatile program memory, RAM, and integrated peripherals in a single IC. The PIC architecture uses a modified Harvard RISC core that executes instructions in a single cycle, allowing the 32MHz clock to deliver up to 8 MIPS of throughput. The PIC16 family sits within the broader 8-bit MCU hierarchy: MCU -> microcontroller -> embedded controller -> semiconductor. These devices target cost- and power-sensitive applications where 32-bit performance is unnecessary but rich analog and communication peripherals are required.
Key features of the PIC16LF15325-I/JQ include 4 PWMs, 1 comparator, a 5-bit DAC, a 10-bit ADC, 4 Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), 2 EUSART modules, and SPI/I2C interfaces. The XLP technology provides multiple low-power sleep modes with currents in the nanoamp range, making the LF variant (1.8V-3.6V operation) ideal for battery-powered designs. The UQFN-16 4x4 mm package provides a compact footprint with an exposed pad for thermal dissipation.
The device uses a 14-bit instruction word with 35 instructions and a 16-level hardware stack. On-chip peripherals are interconnected via Peripheral Pin Select (PPS), allowing flexible signal routing. The integrated Core Independent Peripherals (CLC, CWG, NCO) can operate without CPU intervention, freeing the core for other tasks and reducing active current.
Typical applications include IoT sensor nodes, low-power wireless devices, battery management controllers, LED lighting control, consumer electronics, and industrial sensor interfaces. The 1.8V minimum supply enables direct connection to single-cell Li-coin or 2x AA batteries without boost converters.
When designing with this device, choose the LF (low-voltage) variant when supplies stay below 3.6V, and reserve the F (5V) variant for 5V-tolerant systems. Use PPS to remap peripherals and avoid signal-routing conflicts in tight pin budgets.

Typical Applications
PIC16LF15325-I/JQ is suitable for 6 applications: IoT Wireless Sensor Nodes, Battery-Powered Wearable Devices, LED Lighting Control, Industrial Sensor Interfaces, Consumer Remote Controls, Home Automation Sensor Hubs.
IoT Wireless Sensor Nodes
The PIC16LF15325-I/JQ is well matched to low-power wireless sensor nodes because its 1.8V-3.6V supply range allows direct connection to 2x AA or Li-coin cells, while the XLP sleep modes drop current to nanoamp levels. The 10-bit ADC handles analog sensor inputs (temperature, light, humidity) and the two EUSART modules support UART-based radios like LoRa or BLE modules. The four CLC blocks wake the MCU only when a valid signal pattern arrives, extending battery life. Pair with a low-power radio and the result is a multi-year coin-cell sensor node.
Recommended
Battery-Powered Wearable Devices
For wearable and fitness-tracker designs, the PIC16LF15325-I/JQ's 1.8V minimum supply and XLP nanoamp sleep currents enable multi-month operation on small Li-Ion cells. The CWG peripheral drives haptic feedback or LED pulse patterns without CPU load, and the four PWM channels handle LED brightness or motor control. The 32MHz performance (8 MIPS) supports basic DSP for heart-rate or motion preprocessing before sending data over BLE.
Recommended
LED Lighting Control
The PIC16LF15325-I/JQ's four PWM channels and Complementary Waveform Generator (CWG) provide the hardware building blocks for multi-channel LED drivers and dimming controllers. The 5-bit DAC and comparator enable analog current sensing for closed-loop LED current regulation, while the SPI interface drives external LED driver ICs. The 14KB Flash accommodates color-mixing algorithms and DMX or DALI protocol stacks for architectural lighting.
Recommended
Industrial Sensor Interfaces
Industrial 4-20mA loop-powered sensors benefit from the PIC16LF15325-I/JQ's wide 1.8V-3.6V range, 10-bit ADC for precision measurement, and industrial -40C to +85C temperature rating. The EUSART modules connect to RS-485 transceivers for Modbus RTU or proprietary fieldbus protocols. Core Independent Peripherals (CLC, CWG) handle sensor linearization and HART-style signal modulation without CPU intervention, reducing measurement latency.
Recommended
Consumer Remote Controls
Infrared and RF remote controls benefit from the PIC16LF15325-I/JQ's nanoamp sleep current (extending battery life beyond the shelf life of the cell), EUSART for IR modulation, and CWG for carrier-wave generation. The 4x4 mm UQFN package fits inside compact keyfob form factors, and the 14KB Flash holds multiple device code libraries and button-press debounce logic. Wake-on-change interrupts handle keypress events with zero CPU activity until needed.
Recommended
Home Automation Sensor Hubs
Smart-home temperature, humidity, and occupancy sensor hubs leverage the PIC16LF15325-I/JQ's integrated peripherals: 10-bit ADC reads analog sensors, EUSART/SPI/I2C connect to digital sensors, and CLC cells perform local decision logic without waking the core. The 1.8V operation matches Zigbee or BLE SoC daughter cards operating at 1.8V rails, eliminating level shifters. The XLP deep-sleep modes keep average current below 5 uA for multi-year battery operation on wall-mounted wireless sensors.

Key Differentiators
- Integrated Core Independent Peripherals (CIPs) (vs PIC16LF15324-I/JQ)
- Extended temperature grade option (vs PIC16LF15325-E/JQ)
- Lower minimum supply voltage (vs PIC16F15325-I/JQ)
Design Notes
Estimated: Vdd decoupling requires a 0.1 uF ceramic capacitor placed within 3 mm of the Vdd pin and a bulk 1-10 uF tantalum or ceramic on the same node. For battery-powered designs, place a 100 kohm-Mohm range pull-down on MCLR to prevent spurious resets during battery insertion ramps; Microchip AN2347 covers MCLR hardening in detail.
The 16-UQFN (4x4 mm) exposed thermal pad must be soldered to a PCB copper pad of at least 2x2 mm to meet thermal and mechanical reliability specifications. Connect this pad to VSS to provide low-impedance ground return and improve EMI performance. Use microvia-in-pad or multiple thermal vias to the inner ground plane for high-current switching outputs (PWM, CWG).
Peripheral Pin Select (PPS) remapping must be configured before enabling the peripheral; failure to do so locks signals to their default pins and is a common source of 'no output' debug sessions. Also, the LF variant is NOT 5V tolerant on I/O pins - applying >3.6V to any GPIO damages the part. Use the F variant when interfacing with 5V logic.
Estimated: For SPI runs above 50 mm or I2C at 400 kHz above 30 mm, add 22-33 ohm series damping resistors near the source to reduce reflections. Keep I2C pull-ups between 1 kohm and 10 kohm based on bus capacitance; budget <400 pF total bus cap to meet Fast Mode timing.
