PIC16LF18325-E/JQVAO Overview
A PIC microcontroller (MCU) is a compact programmable processor that integrates CPU, memory, and peripherals on a single die; the PIC16 family targets 8-bit low-power and general-purpose applications, occupying the pico-power branch of Microchip's PIC portfolio between the baseline PIC10/12 and the high-performance PIC18/dsPIC families. PIC microcontrollers dominate the 8-bit embedded segment where deterministic response, ultra-low sleep current, and rich on-chip analog/digital peripherals reduce BOM cost. The PIC16LF18325 specifically combines an enhanced mid-range core with intelligent peripherals and PPS routing.
The PIC16LF18325-E/JQVAO delivers up to 32MHz CPU speed from an internal 32MHz HFINTOSC, with hardware multiplier, 4 CCP modules, 4 CLC blocks, 1 CWG, 1 NCO, and PPS allowing digital peripheral signals to be remapped to most I/O pins. Functional-safety diagnostics and a 10-bit ADC with internal voltage reference are included. VAO indicates the part is qualified for automotive use; the standard E/JQ temperature range is -40C to +125C.
Typical applications include automotive body controllers, sensor nodes, LED lighting modules, consumer IoT edge devices, low-power wearables, and battery management front-ends. The wide operating voltage and XLP sleep currents below 100 nA make it well suited to designs powered by coin cells or energy harvesters.
When designing, plan pin-out using the PPS spreadsheet early, allocate the 16-pin UQFN land pattern with proper thermal relief, and keep analog traces short to preserve ADC accuracy. Use Microchip's MPLAB X IDE and XC8 toolchain for firmware.

Typical Applications
PIC16LF18325-E/JQVAO is suitable for 6 applications: Automotive Body Control Modules, Battery-Powered IoT Sensor Nodes, LED Lighting and Dimming Controllers, Wearable Health and Fitness Devices, Industrial Sensor Signal Conditioning, HVAC and Home Automation Controls.
Automotive Body Control Modules
The PIC16LF18325-E/JQVAO's VAO automotive qualification and -40C to +125C operating range make it suitable for body controllers managing lighting, mirrors, and accessory switches. With 14KB Flash and 12/18 I/O via PPS, the device directly interfaces with multiple LIN sub-nodes and PWM-driven LED matrices. Compared with the PIC16F18325, the LF variant consumes lower sleep current for key-off leakage budgets typically below 100 uA per ECU. The 16-pin UQFN 4x4 footprint supports compact PCB placement behind door panels and seat modules.
Recommended
Battery-Powered IoT Sensor Nodes
The PIC16LF18325-E/JQVAO's XLP nanoWatt sleep currents (typically below 100 nA in sleep with RTCC) make it ideal for coin-cell or energy-harvesting wireless sensor nodes. The 1.8-3.6V VDD range aligns with single-cell Li-ion and CR2032 chemistries without boost conversion, reducing BOM cost. The 10-bit ADC, internal temperature indicator, and CIP peripherals (CLC for sensor wake logic, NCO for tone-based modulation) simplify firmware. Compared with PIC16F1825, the LF variant's lower active current at 32MHz extends battery life by 15-20% in periodic-sampling applications.
Recommended
LED Lighting and Dimming Controllers
The PIC16LF18325-E/JQVAO provides four 10-bit PWM channels plus a dedicated CWG (Complementary Waveform Generator) for driving high-brightness LED strings with dead-band control. The CIP block can implement active freewheeling and constant-current regulation without CPU intervention, freeing the 32MHz core for protocol and user-interface tasks. With PPS remapping, designers can route PWM outputs to most GPIO pins, simplifying PCB routing in space-constrained LED bulb form factors. The 16-pin UQFN 4x4 package fits inside MR16-style lamp bases.
Recommended
Wearable Health and Fitness Devices
The PIC16LF18325-E/JQVAO's 1.8-3.6V operation and nanoWatt XLP modes suit wearable heart-rate, step-counter, and SpO2 sensor hubs powered by small Li-Po batteries. The 10-bit ADC paired with the on-chip op-amp captures PPG and bio-impedance signals; the CLC and NCO blocks can run pattern generation and tone demodulation autonomously. The 16-pin UQFN 4x4 mm footprint allows integration inside wristband modules. Compared with PIC16F1825, the LF variant's reduced active current at 32MHz extends battery life across multi-day wear cycles.
Recommended
Industrial Sensor Signal Conditioning
The PIC16LF18325-E/JQVAO provides on-chip op-amps, comparators, and a 10-bit ADC with internal voltage reference for analog front-end conditioning of 4-20 mA loops, RTD sensors, and bridge transducers. The Core Independent Peripherals (CLC, CWG, NCO) can implement digital filters and PWM-based excitation without loading the CPU, enabling deterministic loop times below 1 ms. The automotive VAO screening also supports factory automation nodes requiring extended temperature endurance. The 16-pin UQFN 4x4 package permits placement inside sealed IP67 transducer heads.
Recommended
HVAC and Home Automation Controls
The PIC16LF18325-E/JQVAO integrates well with HVAC and home automation subsystems requiring low standby current and deterministic response. With CLC implementing zero-crossing detection and the NCO generating precise timer interrupts, the MCU can drive triac-based AC switches and dimmer circuits autonomously. The wide -40C to +125C range and automotive VAO qualification also suit equipment installed in attics or near HVAC plenums. The 16-pin UQFN 4x4 mm footprint and 1.8-3.6V operation match thermostat battery backup and PoE-supplied node designs.

Key Differentiators
- Automotive VAO qualification for under-hood and body ECUs (vs PIC16LF18325-E/JQ)
- Higher flash and RAM over memory-reduced sibling (vs PIC16LF18324-E/JQ)
- Modern CIP peripherals over legacy PIC16F1825 (vs PIC16LF1825-I/JQ)
- Lower-voltage optimized VDD range for battery systems (vs PIC16F18325-E/JQ)
Design Notes
Estimated: At VDD=3.3V and 32MHz active mode, the PIC16LF18325-E/JQVAO draws approximately 1.4 mA (per Microchip PIC16(L)F18325 datasheet typical curves). For battery-budgeted designs, use Sleep mode with RTCC to drop current below 1 uA, retaining RAM and register state. Always place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 7), plus a 10 uF bulk capacitor at the board supply input to handle digital transient currents during CIP-driven switching.
Estimated: The 16-pin UQFN (4x4) has a center exposed thermal pad that must be soldered to a grounded copper pour of at least 10 mm x 10 mm for thermal dissipation and electrical reference. Per Microchip UQFN package guidelines, the thermal pad land pattern should use 5x5 via array (0.3 mm vias) to inner ground plane. Failure to solder the thermal pad increases thermal resistance and may violate the operating temperature budget under continuous 32MHz operation.
Keep analog signal traces (ADC inputs, comparator inputs) short and away from PWM-driven switching traces routed by PPS peripherals. Use a ground guard ring around sensitive analog pins and ensure the analog and digital VDD rails are decoupled separately when using the internal voltage reference. According to the Microchip datasheet, the ADC conversion accuracy degrades above 1 Msps when source impedance exceeds 10 kohm - insert a buffer op-amp or use short traces to maintain accuracy.
Do not exceed the absolute maximum VDD of 4.0V (per Microchip datasheet) - the LF variant is specified for 1.8-3.6V operation and applying 5V will damage the part. When migrating from PIC16F18325 to PIC16LF18325 in existing designs, verify that no 5V signals are connected to any I/O pin. Always configure the PPS unlock sequence before remapping digital peripheral outputs to non-default pins - skipping the unlock writes silently drops peripheral signals.
Compliance Information
VAO suffix indicates automotive qualification per Microchip ordering convention. RoHS and lead-free confirmed per Microchip product page. REACH compliance assumed by Microchip declaration.
