PIC16LF15323-E/P Overview
An 8-bit microcontroller (MCU) is a single-chip computer featuring an 8-bit data bus, on-chip program memory, RAM, and integrated peripherals. PIC microcontrollers from Microchip use a Harvard RISC architecture with separate program and data buses, enabling single-cycle instruction execution. The 8-bit MCU sits in the broader hierarchy: microcontroller -> embedded processor -> semiconductor IC -> integrated circuit. XLP variants such as the PIC16LF15323 add sleep currents measured in nanoamps, qualifying them for battery-powered and energy-harvesting systems.
Key features include 256 bytes of SRAM, four 10-bit PWM modules, a 5-bit DAC, a 10-bit ADC with multiple channels, two comparators, four Configurable Logic Cells (CLCs), a Complementary Waveform Generator (CWG), and serial communication via EUSART, SPI, and I2C. The 14-pin PDIP package is suited to through-hole prototyping, breadboarding, and legacy industrial hardware where surface-mount is not viable. Operating voltage spans 1.8V to 3.6V (LF family), with industrial temperature range of -40C to +125C.
The PIC16LF15323 leverages a 14-bit instruction word with a modified Harvard architecture and a hardware accumulator-based ALU, executing most instructions in one clock cycle. On-chip CIPs (CLC, CWG, NCO, PWM) operate without CPU intervention, freeing the core for application logic and reducing firmware complexity. This combination delivers predictable real-time behavior for closed-loop control tasks at low MHz.
Typical applications include consumer white goods, sensor conditioning nodes, low-power IoT endpoints, LED lighting controllers, battery chargers, and industrial control modules. The XLP sleep currents extend battery life in remote or always-on devices, while CLC and CWG peripherals simplify custom waveform generation without external logic.
When designing with this part, verify the LF voltage range (1.8V-3.6V) matches your system rail; the non-LF PIC16F15323 supports 2.3V-5.5V. The 14-PDIP footprint is convenient for hand-soldered prototypes but is larger than surface-mount alternatives such as SOIC-14 or QFN packages.

Typical Applications
PIC16LF15323-E/P is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, Consumer White Goods Control, LED Lighting Controllers, Low-Power Remote Controls, Industrial Sensor Conditioning, Battery Chargers and Energy Management.
Battery-Powered IoT Sensor Nodes
The PIC16LF15323-E/P's 1.8V-3.6V operating range and XLP nanoamp sleep currents make it ideal for battery-powered IoT sensor nodes running on a single CR2032 or two-AA cells. Its 32MHz PIC16 core executes sensor reads and EUSART/SPI/I2C transmissions in milliseconds before returning to deep sleep, while four CLCs handle signal conditioning without CPU wakeups. The 10-bit ADC and built-in comparators connect directly to analog sensors such as thermistors, photodiodes, or capacitive touch electrodes. Compared to discrete logic, the integrated CIPs reduce BOM and PCB area, while the 14-PDIP package simplifies hand-soldered prototyping and field service replacements.
Recommended
Consumer White Goods Control
The PIC16LF15323-E/P fits small consumer appliances such as coffee makers, blenders, and HVAC zone controllers where 14-PDIP through-hole mounting aids assembly-line manufacturing and field repair. Its 4-channel 10-bit PWM drives brushed DC motors, valves, or LED indicators, while the 5-bit DAC and comparators handle analog trim and over-current detection. The 3.5KB Flash holds UI state machines, error handlers, and bootloader upgrades, and the CWG simplifies dead-time control for half-bridge outputs. Compared to pure discrete designs, the integrated peripheral set cuts component count and improves EMI compliance through firmware-controlled switching.
Recommended
LED Lighting Controllers
The PIC16LF15323-E/P delivers precise PWM-driven LED dimming with the CWG producing complementary outputs that drive half-bridge MOSFET stages. Four CLCs implement custom dimming curves, color-mixing logic, or thermal foldback without CPU cycles. The 10-bit PWM resolution at 32MHz allows smooth fades below the human perception threshold. The 1.8V minimum rail is convenient for two-cell alkaline or single-cell lithium designs in strip lighting and architectural fixtures. Compared to discrete 555-timer-based PWM controllers, the integrated MCU enables addressable lighting, OTA firmware updates, and energy metering on the same die.
Recommended
Low-Power Remote Controls
The PIC16LF15323-E/P powers handheld remote controls with multi-year coin-cell battery life thanks to XLP technology and wake-on-pin-change interrupts. Its built-in comparators detect button-matrix presses without external pull-ups in many configurations, while the CLCs debounce and debounce-latch signals in hardware. The 32MHz core supports IR or sub-GHz RF protocol generation when paired with a transmitter, with EUSART driving UART-based modules. Compared to dedicated encoder ICs, the integrated MCU allows firmware-driven protocol upgrades and custom button mappings.
Recommended
Industrial Sensor Conditioning
The PIC16LF15323-E/P suits industrial 4-20mA loop sensors, RTD conditioners, and bridge amplifier digitizers requiring on-chip signal processing. The 10-bit ADC with internal voltage reference, two comparators, and 5-bit DAC form a complete analog front-end for temperature, pressure, or strain-gauge bridges. The EUSART/SPI/I2C peripherals connect to HMI displays, isolated transceivers, or local IO-Link masters. The -40C to +125C industrial temperature range supports outdoor and process-control environments. Compared to ASIC analog front-ends, the programmable MCU enables custom linearization and calibration in firmware.
Recommended
Battery Chargers and Energy Management
The PIC16LF15323-E/P manages single-cell lithium or NiMH charging with built-in ADC monitoring battery voltage and CWG driving synchronous buck stages. The CLCs implement charge-state logic, safety timers, and temperature foldback without firmware intervention. The 1.8V-3.6V operating range is compatible with single-cell lithium directly, while the 32MHz core performs coulomb counting and state-of-health calculations. The 14-PDIP package simplifies bench characterization and small-batch production. Compared to dedicated charger ASICs, the MCU allows custom charge profiles, fuel-gauge displays, and USB-C PD negotiation via firmware.

Design Notes
The PIC16LF15323-E/P operates from 1.8V to 3.6V and integrates XLP technology with nanoamp sleep currents. Decouple VDD (pin 14) with a 100nF ceramic capacitor placed within 5mm of the pin and a bulk 1-10uF tantalum or ceramic for transient suppression. Place a small (1kohm-10kohm) series resistor on MCLR to limit inrush during ICSP programming. Avoid exceeding 3.6V on any I/O pin; the LF variant is NOT 5V-tolerant unlike the F variant.
Route the ICSP clock and data lines (typically RA0 and RA1) with short traces and avoid placing high-current switching nodes within 5mm. Place the decoupling capacitor ground return directly to the VSS pin using a via or short trace to minimize loop area. For PCB layouts using the 14-PDIP footprint, leave room for an ICSP header footprint (RJ-11 6-pin or 0.1-inch 5-pin SIP) adjacent to the MCU for in-circuit programming and debug.
Do not assume 5V tolerance on the LF variant - the PIC16LF15323 is rated 3.6V absolute maximum. If interfacing to a 5V sensor or transceiver, add a level shifter or choose the PIC16F15323 variant. Also note that configuration word settings must be reviewed after any reset: WDT, brown-out, and code protection bits are sticky and incorrect settings can lock out ICSP. Use MPLAB X IDE or MPLAB IPE to verify configuration word state before debugging unexpected behavior.
The PIC16LF15323's PWM, CWG, and EUSART outputs can produce fast edges that couple into adjacent analog traces. Keep analog ADC inputs (ANx pins) at least 3 trace widths away from PWM outputs, and add a small RC filter (1kohm + 100pF) on analog inputs in noisy environments. The 10-bit ADC is sufficient for general-purpose sensing but is not a substitute for a dedicated audio or precision measurement ADC. For high-frequency external clocks, place the crystal within 5mm of OSC1/OSC2 with grounded guard traces.
