PIC16LF15323-E/SL Overview
What is an 8-bit PIC microcontroller? It is a microcontroller based on Microchip's 8-bit RISC architecture that combines a small instruction set, integrated Flash memory, RAM, and on-chip peripherals such as ADCs, timers, PWM modules, and communication peripherals (EUSART, SPI, I2C). Within the broader taxonomy: PIC16F/LF15323 belongs to the PIC16 family -> 8-bit PIC MCUs -> microcontrollers -> integrated circuits -> semiconductors. The 15323 sub-family is positioned as a low-power, peripheral-rich upgrade to legacy PIC16F193x devices, adding modern CIPs and richer analog while preserving instruction-set and footprint compatibility for legacy 14-pin PIC designs.
Key differentiating features include the 32 MHz internal oscillator with ±1% accuracy, four Configurable Logic Cells that let designers implement custom glue logic without external gates, and the CWG which generates complementary PWM outputs with programmable dead-band control - directly useful for half-bridge and full-bridge driver interfaces. The integrated 5-bit and 8-bit DACs provide voltage references for comparators or simple waveform generation without external components.
Typical applications for the PIC16LF15323-E/SL include IoT sensor nodes, low-power wireless remotes, LED lighting controllers, small appliances with HMI buttons, motor-control companion MCUs, and battery-powered consumer devices. The combination of small 14-pin SOIC footprint, low cost, and rich on-chip peripherals makes it a strong fit when designers want to replace discrete analog + logic circuitry with a single MCU.
When designing with this part, leverage the MPLAB X IDE and MPLAB Code Configurator (MCC) to configure CIPs graphically and avoid manual peripheral register programming. Pay attention to the 1.8V-3.6V VDD constraint - this is the LF variant; the F variant (PIC16F15323) supports up to 5.5V for 5V-system designs.

Typical Applications
PIC16LF15323-E/SL is suitable for 6 applications: Battery-Powered IoT Sensor Node, LED Lighting Controller with Dimming, Small Appliance HMI with Buttons and Display, Low-Power Wireless Remote Control, BLDC Motor Companion Controller, Portable Medical Wearable Sensor.
Battery-Powered IoT Sensor Node
The PIC16LF15323-E/SL is well suited to IoT sensor nodes because its 1.8V-3.6V VDD range matches a single Li-ion or 2xAA cell, and its nanoamp-level XLP sleep modes allow duty-cycled sensing that preserves battery life for years. Its 10-bit ADC and four CLCs handle local sensor signal conditioning and digital filtering, while the integrated EUSART/SPI/I2C interfaces connect directly to sub-GHz or BLE modules. Versus larger Cortex-M0+ MCUs that require buck converters, the PIC16LF15323-E/SL eliminates the power stage and reduces BOM cost by 30-50% in low-bandwidth sensor designs.
Recommended
LED Lighting Controller with Dimming
The four 16-bit PWM channels and Complementary Waveform Generator (CWG) make the PIC16LF15323-E/SL a strong fit for multi-channel LED drivers and dimming controllers. Each PWM provides 16-bit resolution for smooth logarithmic dimming curves, and the CWG adds programmable dead-band control for synchronous buck or boost LED driver topologies. The 1.8V-3.6V VDD range lets it run directly from battery or USB-derived rails without a boost converter, while the four CLCs implement over-current protection and color-mixing logic without external gates.
Recommended
Small Appliance HMI with Buttons and Display
The PIC16LF15323-E/SL works well as the HMI controller in small appliances because its four CLCs implement button-debounce and rotary-encoder logic without external gates, and its 10-bit ADC reads potentiometer or NTC inputs for temperature selection. The 14-SOIC footprint fits compact appliance PCBs while the CWG drives a small buzzer or piezo for audible feedback. Versus discrete 555-based HMI designs, the MCU replaces 3-5 analog ICs and adds configurable behavior via firmware updates.
Recommended
Low-Power Wireless Remote Control
Battery-powered wireless remotes benefit from the PIC16LF15323-E/SL's XLP sleep currents and instant wake-up via interrupt-on-change. The MCU stays in sleep for years between button presses, then wakes in microseconds to encode a button event over SPI or UART to a sub-GHz transmitter. Its small 14-SOIC footprint suits the tight constraints of handheld enclosures, and the integrated comparators detect low-battery conditions without external components.
Recommended
BLDC Motor Companion Controller
The Complementary Waveform Generator (CWG) and four PWMs make the PIC16LF15323-E/SL a competent companion controller for small BLDC motors driving pumps or fans. It generates complementary gate-drive signals with programmable dead-band, then exchanges speed/torque commands with a host processor over EUSART. The 32 MHz core handles trapezoidal commutation at up to several kHz switching frequency, while the integrated comparators sense back-EMF for sensorless control in cost-sensitive designs.
Recommended
Portable Medical Wearable Sensor
The PIC16LF15323-E/SL is a strong fit for wearable medical sensors such as pulse oximeters and single-lead ECG patches because its 1.8V minimum VDD matches coin-cell batteries and its nanoamp sleep currents extend battery life to weeks. Its 10-bit ADC with internal voltage reference reads photodiode or electrode signals, while the DAC generates bias voltages for analog front-ends. The extended -40C to +125C temperature grade supports sterilization and continuous skin-contact operation, and the 14-SOIC package is small enough for wristband form factors.

Key Differentiators
- Lowest VDD in family supports single-cell battery designs (vs PIC16F15323-E/SL)
- Extended temperature grade for industrial and automotive (vs PIC16LF15323-I/SL)
- Compact 14-SOIC footprint with full peripheral set (vs PIC16LF15313-I/SL)
Design Notes
Estimated: at 32 MHz active and 3.3V VDD, the PIC16LF15323 draws approximately 1.4 mA typical. In Sleep mode with WDT disabled, current drops below 50 nA. For battery designs, configure IDLE/DOZE modes and gate peripherals off via PMD registers to maximize runtime. Always place a 100 nF decoupling capacitor within 5 mm of VDD pin 1.
Do not exceed 3.6V on the LF variant; even brief transients above 4V can damage the part. The MCLR pin (RA3) is the only true input-only pin; configuring it as output will prevent reset functionality. When migrating from F to LF variant, verify analog reference voltage (FVR buffer is 1.024V/2.048V/4.096V - the 4.096V tap is unavailable on LF at 3.3V).
The 14-SOIC package benefits from a 4-layer PCB with a continuous ground pour under the IC. Keep the 32 MHz HFINTOSC traces short and avoid routing near analog ADC inputs (RA0/RA1) to minimize digital crosstalk. The exposed copper pour under the SOIC body is non-functional (no thermal pad) but improves mechanical solder joint reliability.
Compliance Information
RoHS compliance per Microchip product page. AEC-Q100 automotive qualification is available separately on PIC16F15323-E/SL automotive-graded variants - LF industrial-grade parts are not AEC-Q100 qualified by default.
