PIC16LF15323-I/P Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, peripherals, and I/O on one silicon die. The PIC16 family belongs to the 8-bit microcontroller category within the broader embedded MCU taxonomy (8-bit MCU -> microcontroller -> embedded controller -> semiconductor IC). The 'LF' prefix denotes the eXtreme Low-Power (XLP) process node optimized for battery-powered and energy-harvesting designs where nanoWatt sleep currents are critical to extending operating life.
Key features include four Configurable Logic Cells (CLC), two comparators with selectable reference, a 5-bit DAC, a 10-bit ADC with up to 11 channels, four 10-bit PWM channels, a Complementary Waveform Generator (CWG), an Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART), and SPI/I2C peripherals. The device supports 1.8 V to 3.6 V operation and includes a Watchdog Timer with a dedicated on-chip oscillator for robust operation in noisy environments.
The PIC16LF15323 architecture employs a 14-bit instruction word RISC pipeline with single-cycle execution for most instructions, delivering up to 16 MIPS at 32 MHz. Core Independent Peripherals (CIPs) such as the CLC and CWG allow complex waveform and logic functions to operate without CPU intervention, freeing the core for application code. This combination of high analog integration, low power, and autonomous peripheral operation makes the device well suited to compact, cost-sensitive designs.
Typical applications include IoT sensor nodes, low-power wireless remote controls, battery-powered HVAC thermostats, LED lighting controllers, small appliance control boards, and consumer electronics front-panel interfaces. The 14-pin PDIP format also makes the part attractive for hobbyist, educational, and through-hole prototype builds where socketed programming and easy rework are valuable.
When designing with this MCU, ensure all unused I/O pins are configured as outputs low or inputs with internal pull-ups enabled to minimize sleep current. Select the appropriate oscillator mode (HFINTOSC at 32 MHz or LFINTOSC at 31 kHz) for the active workload, and place the device into Sleep with peripherals selectively disabled when possible.

Typical Applications
PIC16LF15323-I/P is suitable for 6 applications: IoT Sensor Node Controller, Battery-Powered HVAC Thermostat, LED Lighting Controller, Wireless Remote Control Unit, Small Appliance Control Board, Consumer Front-Panel Interface.
IoT Sensor Node Controller
The PIC16LF15323-I/P is well matched to low-power IoT sensor node controllers thanks to its eXtreme Low Power (XLP) architecture, 10-bit ADC with up to 11 input channels, and nanoWatt-class Sleep current. Battery-powered sensors that wake briefly to sample and transmit can extend coin-cell life by 2-5x compared to non-XLP MCUs. The CLC and CWG peripherals allow autonomous sensor gating without CPU intervention. With 3.5 KB of Flash and 256 B of SRAM, the device runs state-machine firmware and small protocol stacks in compact footprints. The 14-pin PDIP format simplifies prototype and field-replaceable module designs.
Recommended
Battery-Powered HVAC Thermostat
The PIC16LF15323-I/P suits battery-powered HVAC thermostat designs through its combination of low sleep current, integrated temperature-friendly peripherals, and analog integration. Two comparators plus the 10-bit ADC can directly read thermistor bridges without external analog ICs, while the four 10-bit PWM channels drive triac-fired heating elements or PWM-controlled fans. The XLP Sleep mode drops current into the nanoamp range between samples, so a pair of AA cells can power the thermostat for multiple years. The 14-pin PDIP form factor is convenient for hand-solderable thermostat PCBs.
Recommended
LED Lighting Controller
The PIC16LF15323-I/P integrates well into multi-channel LED lighting controllers via its four 10-bit PWM channels, Complementary Waveform Generator (CWG), and 5-bit DAC for current-set references. The CWG can drive half-bridge LED driver stages without software overhead, while PWMs handle brightness and color mixing. Core Independent Peripherals (CIPs) offload LED sequencing, freeing CPU cycles for protocol or user-interface tasks. With 256 B of SRAM and 3.5 KB of Flash, the device supports firmware for animated lighting patterns and DMX-512-lite style protocols. The 14-pin PDIP package eases early-stage prototype rework.
Recommended
Wireless Remote Control Unit
The PIC16LF15323-I/P is a strong fit for handheld wireless remote control units where every microamp matters. The integrated EUSART and SPI/I2C peripherals interface directly to popular sub-GHz transceivers (e.g., Microchip MRF89XA or third-party CC1101), while the four Configurable Logic Cells (CLC) encode button matrices and IR protocols in hardware. XLP technology extends coin-cell battery life by minimizing sleep current between button presses. The 14-pin PDIP package is friendly to through-hole prototyping and field-replaceable battery compartments.
Recommended
Small Appliance Control Board
The PIC16LF15323-I/P works in small appliance control boards (coffee makers, fans, blenders) that need reliable digital control plus analog sensing. Its 32 MHz core gives 16 MIPS, enough to run user-interface state machines, while the 10-bit ADC reads temperature, motor current, and water-level sensors. The comparators enable zero-cross detection for triac control, and the CWG generates dead-band-corrected complementary drive signals for synchronous rectification or half-bridge motor control. The 14-pin PDIP form factor is well suited to high-volume through-hole production or hand-soldered prototyping in cost-sensitive consumer appliance markets.
Recommended
Consumer Front-Panel Interface
The PIC16LF15323-I/P serves consumer front-panel interfaces such as microwave keypads, washing-machine displays, and audio equipment controls. Its CLC blocks can scan 4x4 key matrices without CPU load, while the EUSART or SPI can drive LED or character-LCD display drivers. The 5-bit DAC provides reference voltages for contrast or backlight brightness control. The 14-pin PDIP package makes it easy to assemble and rework during high-mix low-volume runs, while the XLP Sleep current keeps standby power well below regulatory limits.

Key Differentiators
- XLP nanoWatt Sleep vs standard F-process (vs PIC16F15323-I/P)
- Lowest memory and lowest cost variant in 14-pin PDIP (vs PIC16LF15325-I/P)
- Through-hole PDIP format for prototyping and socketed programming (vs PIC16LF15323-I/SL)
Design Notes
To achieve minimum sleep current, configure all unused I/O pins as outputs driving low, or as inputs with internal weak pull-ups enabled. Disable unused peripherals via their PMDx control bits, and select the LFINTOSC 31 kHz source as the system clock during Sleep. The PIC16LF15323-I/P typical Sleep current is in the nanoamp range, so even a few unconfigured pins can dominate standby power budget in battery applications.
Estimated: at maximum operating frequency of 32 MHz with VDD = 3.6 V across the full industrial temperature range, core current is approximately 7 mA, giving core power dissipation of about 25 mW. For the 14-pin PDIP package (theta_JA approximately 70 C/W), junction temperature rise above ambient is roughly 1.8 C. Thermal concerns are minimal for this MCU, but ensure PCB thermal vias under any exposed pad (none on PDIP) and adequate ground plane coverage for EMI.
Place the VDD bypass capacitor (100 nF ceramic) within 5 mm of the VDD pin (pin 1) and a bulk 10 uF tantalum or ceramic within 25 mm. Keep the MCLR/RA3 pin trace short and avoid routing noisy digital signals across the analog-capable pins (RA0-RA2, RC0-RC5). For ADC accuracy, add a small RC filter on the analog supply rail and route analog grounds back to a single-point ground star.
Do not exceed the absolute maximum VDD of 4.0 V (LF) or 6.5 V (F) on the PIC16LF15323-I/P, even briefly during in-circuit serial programming. The LF process supports up to 3.6 V regulated operation only - applying 5 V will damage the part. Also, MCLR must be tied to VDD through a 10 kohm pull-up if not used as a reset source. Forgetting the MCLR pull-up is a common cause of intermittent programming failure.
