PIC16F15323-E/SL Overview
A PIC16 8-bit microcontroller is a compact RISC processor built on Microchip's Enhanced Mid-Range Core, executing 49 instructions across 16 stack levels. Within the broader taxonomy, the PIC16F15323 belongs to the microcontroller (MCU) family, then to 8-bit MCUs, then to the PIC16 enhanced mid-range sub-family, and finally to the XLP (eXtreme Low-Power) category that targets battery-powered and always-on embedded designs. The PIC16F153xx line introduces Core Independent Peripherals (CIPs), Intelligent Analog, and Peripheral Pin Select (PPS), enabling designers to offload tasks such as signal generation, waveform detection, and communication framing from the CPU.
Key differentiating specifications include: a 32MHz maximum CPU clock (8MHz instruction rate with 4-cycle execution), 12 I/O pins with PPS remapping, four 10-bit PWMs with complementary waveform generation, two operational amplifiers or comparators, a 5-bit DAC, a 10-bit ADC with up to 11 channels, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), and EUSART plus SPI/I2C communication. The device also integrates the eXtreme Low-Power (XLP) IDLE and DOZE modes plus Peripheral Module Disable (PMD) for fine-grained power gating. On-chip peripherals such as the CLC, CWG, and NCO let complex timing or logic tasks run without CPU intervention, reducing firmware complexity and active-mode current.
Typical applications include battery-powered IoT sensor nodes using the XLP sleep modes, LED lighting controllers leveraging the 4x PWMs and CWG for high-resolution dimming, consumer appliances requiring touch or capacitive sensing through the CIP block, low-cost motor control loops, and small home appliances where the integrated op-amps remove external analog components. The -E (extended) temperature grade and 14-SOIC footprint also suit industrial control boards and distributed sensor hubs.
Designers should budget for a 1.8V to 5.5V supply, ensure decoupling on VDD with a 100nF ceramic cap placed within 5mm of the pin, and reserve the ICSP/ICD pins for in-circuit programming and debugging. The PPS feature lets peripheral signals be remapped across most I/O pins, simplifying PCB routing when the same die must fit multiple board layouts.
For sourcing, the PIC16F15323-E/SL is widely stocked at major distributors in tube packaging as of 2026-09-19. The same die ships in 8-pin variants (PIC16F15313) and larger pin-count variants (PIC16F15344, PIC16F15356), giving designers a migration path within the family.

Typical Applications
PIC16F15323-E/SL is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, LED Lighting and Dimming Controllers, Small Home Appliances and White Goods, Capacitive Touch and User Interface, Industrial Sensor Conditioning, Low-Cost Motor Control (BLDC / Stepper).
Battery-Powered IoT Sensor Nodes
The PIC16F15323-E/SL fits battery-powered IoT sensor nodes because its XLP IDLE/DOZE modes plus PMD gating drop sleep current into the nanoampere range, while the integrated 10-bit ADC and EUSART/I2C peripherals remove external analog and communication ICs. Operating from 1.8 V to 5.5 V lets a single coin cell or 2x AA supply power the whole node. The 3.5 KB Flash is ample for typical sensor-fusion or LoRa-WAN-style framing firmware, and PPS remapping simplifies PCB routing when the same design is reused across multiple sensor SKUs.
Recommended
LED Lighting and Dimming Controllers
For LED lighting and dimming, the PIC16F15323-E/SL provides 4x 10-bit PWMs plus a Complementary Waveform Generator (CWG) that produces non-overlapping gate drive for half-bridge LED FETs. The 4 CLCs can implement dead-time compensation, current-limit blanking, and brown-out protection without CPU load. The 32 MHz core executes high-resolution dimming curves in software while the integrated op-amps close the current-sense loop. This makes the part ideal for smart bulbs, architectural dimmers, and RGBW strips where a single MCU replaces several discrete analog blocks.
Recommended
Small Home Appliances and White Goods
The PIC16F15323-E/SL suits small home appliances such as coffee makers, blenders, and rice cookers because its 12 I/O pins drive keypads, seven-segment displays, and triac interfaces, while the 2 op-amp/comparator blocks handle temperature sensing and motor-current feedback. The extended -40C to +125C temperature grade tolerates the warm enclosures of kitchen appliances. The integrated CWG can produce zero-crossing or PWM control signals for AC loads, eliminating external timer ICs and shrinking the BOM. The same die also fits HVAC damper controllers and simple white-goods user-interface boards.
Recommended
Capacitive Touch and User Interface
Using Microchip's mTouch sensing framework, the PIC16F15323-E/SL turns 12 I/O pins into capacitive touch channels for buttons, sliders, and proximity sensors on appliance front panels and IoT wall switches. The Core Independent Peripherals (CIPs) - CLC, CWG, and NCO - handle the touch-scan timing in hardware, freeing the CPU for communication and backlight control. The 5-bit DAC calibrates the touch threshold per channel, while PPS remapping lets the touch electrodes route to the most PCB-friendly pins, simplifying industrial-design layout versus rigid-pin microcontrollers.
Recommended
Industrial Sensor Conditioning
In industrial 4-20 mA loop-powered sensor transmitters, the PIC16F15323-E/SL acts as the local MCU digitizing a sensor bridge, performing linearization and outputting over SPI/I2C or UART. Its 2 op-amps implement low-side current sensing and rail-to-rail signal conditioning, while the 10-bit ADC delivers adequate resolution for pressure, temperature, and flow sensing. The 1.8-5.5 V supply range simplifies battery or harvested-energy designs, and the extended temperature grade handles factory-floor thermal envelopes. PPS routes ADC channels to analog-friendly pins for optimal PCB layout.
Recommended
Low-Cost Motor Control (BLDC / Stepper)
For cost-sensitive BLDC or stepper motor control, the PIC16F15323-E/SL combines 4 PWMs with the CWG to drive half-bridge or full-bridge FET stages, while the 2 op-amps implement back-EMF sensing and current-limit feedback. The 32 MHz core runs sensorless commutation algorithms or simple PID loops in firmware. Because the CLC can mix PWM with comparator outputs, hardware-level fault detection occurs within nanoseconds, protecting the FETs from shoot-through. This makes the part suitable for small fans, pumps, and consumer robotics where a dedicated motor controller is overkill.

Design Notes
Decouple VDD (pin 14) with a 100 nF X7R ceramic capacitor placed within 5 mm of the pin, and add a bulk 1-10 uF capacitor near the MCU for sleep-mode transient support. For XLP designs targeting nanoampere sleep, disable unused peripherals via PMD and configure all unused I/O as outputs low to avoid floating-input leakage. The 1.8 V to 5.5 V supply range supports direct coin-cell or 2x AA operation without an LDO.
Route the ICSPDAT (pin 1) and ICSPCLK (pin 2) signals to a programming header with no series resistors, and ensure the MCLR/VPP line (pin 4) has its typical 10 kohm pull-up plus a 100 nF cap to VPP for in-circuit programming. Keep analog traces (ADC and op-amp inputs) short and guard them with a ground pour. PPS allows most peripheral signals to remap to alternate pins, so route critical signals to the most PCB-friendly locations.
Do not leave MCLR floating - a missing pull-up on pin 4 causes spurious resets. When using the ADC, configure the A/D conversion clock and acquisition time per the datasheet's ADC section; incorrect Tad settings produce inaccurate readings. For low-power designs, configure the CLC, CWG, and PWM outputs as needed before entering sleep to avoid waking on unintended transitions. Always verify the BOR (Brown-Out Reset) and POR (Power-On Reset) configuration bits match your supply ramp profile.
