PIC16LF15325T-I/JQ Übersicht
A PIC microcontroller (Programmable Interrupt Controller, but historically Peripheral Interface Controller) is an 8/16/32-bit RISC-based MCU manufactured by Microchip Technology and widely used in embedded systems for sensing, control, and human-interface tasks. PIC MCUs integrate a CPU core, non-volatile Flash program memory, volatile SRAM, EEPROM data memory, and a rich mix of peripherals (ADC, PWM, UART, I2C, SPI, comparators, timers) onto a single silicon die. Within the broader taxonomy, the PIC16LF15325 belongs to the enhanced mid-range PIC16F family -> PIC16 family -> 8-bit PIC MCU -> microcontroller -> embedded computing -> semiconductor. Its LF prefix indicates operation down to 1.8V for lithium-battery and energy-harvesting applications, distinguishing it from the F-variant (2.3V-5.5V).
Key features include 4x10-bit PWM channels with complementary outputs, 4 Configurable Logic Cells for glue-logic replacement without external gates, a Complementary Waveform Generator (CWG) for half/full-bridge driver control, 10-bit ADC with computation engine, and a 5-bit/8-bit DAC for set-point generation. Two EUSART blocks support RS-232/RS-485 with auto-baud detection. The on-chip 32 MHz high-precision oscillator eliminates external crystals in many designs.
Architecturally the PIC16LF15325 uses a 14-bit instruction word, 8-level hardware stack, and single-cycle ALU with 32 MHz internal clock. Peripherals are interconnected through Microchip's Peripheral Pin Select (PPS) subsystem, allowing nearly every digital function to be remapped to most I/O pins - useful for BOM consolidation and PCB layout flexibility.
Typical applications include low-power IoT sensor nodes, battery-powered home automation, LED lighting controllers, simple motor/valve control loops, consumer appliances, and wearable health monitors. For automotive-grade requirements, Microchip offers separate AEC-Q100 qualified variants in the PIC16F153xx family.
When designing with this device, ensure the exposed pad (EP) is soldered to a continuous ground plane for thermal and electrical performance. Configure PPS before enabling peripherals, and place a 100 nF decoupling capacitor within 3 mm of each VDD pin.

Battery-Powered IoT Sensor Node
The PIC16LF15325T-I/JQ is well suited for battery-powered IoT sensor nodes thanks to its 1.8V-3.6V wide operating range and XLP nanoWatt technology. The PIC16LF15325's deep-sleep current below 50 nA typical allows a single CR2032 coin cell (~220 mAh) to power a periodic temperature/humidity wake-measure-transmit loop for over 5 years of service life. The on-chip 10-bit ADC with computation engine reduces firmware burden by handling oversampling and averaging in hardware, while the four Configurable Logic Cells (CLC) glue peripheral triggers without waking the CPU. Pair this MCU with an SPI temperature sensor and an EUSART-attached LoRa or Sub-GHz transceiver module; PPS pin-select lets you route SPI to any I/O, easing PCB routing.
Empfohlen
Home Automation Light Switch
The PIC16LF15325T-I/JQ fits capacitive-touch wall switches for smart-home retrofit because its CWG can directly drive a triac optocoupler for AC mains dimming without an external gate driver IC. The PIC16LF15325's four 10-bit PWMs and CLC blocks generate phase-controlled dimming waveforms, while the on-chip 8-bit DAC provides an analog set-point for tunable-white LED fixtures. Operating voltage range 1.8V-3.6V lets a small capacitive-dropper supply run the MCU directly from 230V AC with no bulky transformer. The exposed thermal pad ensures the UQFN-16 (4x4) dissipates the small (~20 mA active) load comfortably in sealed wall-box enclosures.
Empfohlen
Wearable Fitness Band
The PIC16LF15325T-I/JQ is an ideal MCU for entry-level wearable fitness bands because of its tiny UQFN-16 (4x4 mm) footprint, sub-50 nA deep-sleep current, and built-in 10-bit ADC. The PIC16LF15325 can wake on an external interrupt from a heart-rate sensor or accelerometer, capture samples through its ADC, process simple step-counting in firmware, store in 1KB SRAM buffer, and return to sleep - all under 50 uA average current. The EUSART block connects directly to a BLE module (e.g., RN4870) for smartphone syncing, while the I2C block drives the OLED display. XLP technology preserves coin-cell battery life across months of continuous wear.
Empfohlen
Small BLDC Motor Controller
The PIC16LF15325T-I/JQ can act as the supervisory MCU in a small sensorless BLDC motor controller for fans, pumps, or appliance blowers. The PIC16LF15325's Complementary Waveform Generator (CWG) produces complementary PWM outputs with programmable dead time, which directly drives the high-side/low-side gate-driver inputs for a 3-phase inverter. The four 10-bit PWMs support speed-control and current-limit loops, while the on-chip 10-bit ADC samples back-EMF for sensorless commutation. The PIC16LF15325's 32 MHz CPU and 1KB SRAM are sufficient for a trapezoidal commutation algorithm running at 30 kHz PWM frequency. Use the I2C bus to receive speed commands from a host controller.
Empfohlen
Industrial 4-20 mA Loop Transmitter
The PIC16LF15325T-I/JQ serves well in industrial 4-20 mA current-loop sensor transmitters where its wide 1.8V-3.6V supply range and rugged -40C to +85C industrial temperature rating matter. The PIC16LF15325's on-chip 10-bit ADC digitizes bridge-type pressure/flow sensors, while the on-chip 8-bit DAC and PWM-driven op-amp loop generate a precision 4-20 mA output proportional to measured process variable. The two EUSART blocks support HART or RS-485 Modbus communication overlay. The CLC blocks implement watchdog and fault-detection logic without external gates, reducing BOM cost in field-mounted instrumentation.
Empfohlen
Consumer Appliance User Interface
The PIC16LF15325T-I/JQ is well matched to mid-tier consumer appliance user-interface boards (microwaves, washing machines, coffee makers) that need capacitive touch buttons, LED indicators, and a serial link to a host controller. The PIC16LF15325's 10-bit ADC reads multiple capacitive-touch pads via an RC-charge timing technique, its four PWMs drive LED brightness with hardware fade, and its I2C port links to a main appliance controller. The 14KB Flash accommodates menu logic and diagnostic routines, while XLP sleep mode keeps standby power below 100 uA for ENERGY STAR compliance.

- Wider voltage range than F-variant (vs. PIC16F15325-I/JQ)
Designhinweise
The PIC16LF15325T-I/JQ UQFN-16 package exposes a thermal pad on its underside. This pad MUST be soldered to a continuous ground plane for both electrical reference and thermal dissipation. Use an array of 4x4 thermal vias (0.3 mm drill) under the EP to provide a low-impedance ground path. Place a 100 nF decoupling capacitor within 3 mm of the VDD pin and a bulk 1 uF to 10 uF tantalum or ceramic within 10 mm of the supply.
Estimated deep-sleep current draw for the PIC16LF15325T-I/JQ is approximately 30 nA with WDT disabled and 800 nA with WDT enabled per the Microchip XLP datasheet section. For battery-life calculations, use the Active current (~50 uA/MHz at 3.3V) plus the peripheral-on currents. To minimize sleep current, disable the ADC, comparators, FVR, and unused peripherals before issuing the SLEEP instruction; leaving them enabled can add several microamps.
Per Microchip Peripheral Pin Select (PPS) configuration, assign digital peripherals to physical I/O pins in firmware using the PPSLOCK register sequence. Unused I/O pins should be configured as outputs low (not high-impedance inputs) to prevent supply-current leakage through floating CMOS input gates. Reserve one I/O as a SWD/ICSP clock (ICSCLK on RB7) and one for ICSIO (RB6) to retain in-circuit serial programming capability on the final PCB.
Do not exceed the absolute maximum VDD of 4.0V on the LF variant - the LF parts have thinner gate oxides optimized for 1.8-3.6V operation. For 5V-tolerance, use the F-variant PIC16F15325. Also, the MCLR pin requires a 10 kohm pull-up to VDD; a floating MCLR can cause spurious resets in noisy environments. When debugging, ensure the debugger ICD signal does not conflict with the PPS assignments of timer or UART peripherals.
For SPI bus speeds above 8 MHz on the PIC16LF15325, add 33 ohm series-termination resistors near the MCU SCK pin to dampen reflections on long PCB traces. The I2C bus requires external pull-up resistors (typically 2.2 kohm at 400 kHz Fast Mode, 4.7 kohm at 100 kHz Standard Mode) since the PIC16LF15325 has true open-drain I2C pads only on RC0/RC1 by default. Use PPS to remap I2C to other pins if board layout requires it.
