PIC16LF15324-I/P Overview
An 8-bit microcontroller (MCU) is a small computer-on-a-chip combining a CPU, memory, and peripherals around a Harvard architecture. Within the semiconductor taxonomy, an MCU sits under microcontrollers -> integrated circuits -> semiconductors. The PIC16 family uses Microchip's enhanced mid-range 8-bit core, offering deterministic instruction execution at one instruction per clock cycle. PIC MCUs are widely deployed in cost-sensitive embedded applications where software simplicity, low power, and broad peripheral integration outweigh raw compute throughput.
Key features of the PIC16LF15324-I/P include four 10-bit PWM channels, a 5-bit DAC, a comparator, a 10-bit ADC with computation, four Configurable Logic Cells (CLCs), a Complementary Waveform Generator (CWG), two EUSART modules, and two MSSP peripherals that can be configured as either SPI or I2C. The device also provides a wide operating voltage range from 1.8V to 3.6V, idle and sleep current in the microamp range, and peripheral pin select (PPS) for flexible signal routing. The on-chip Core Independent Peripherals (CIPs) allow hardware-level state handling without CPU intervention, freeing the core for higher-level tasks.
Architecturally, the PIC16LF15324 uses an 8-bit data path with a 14-bit instruction word, delivering roughly 8 MIPS peak throughput at 32 MHz. The CIP set, including CLCs and CWG, lets designers implement glue logic, waveform synthesis, and event-triggered tasks entirely in hardware, which reduces firmware complexity and improves determinism. The XLP technology combines multiple low-power modes with fast wake-up times to extend battery life in duty-cycled applications.
Typical applications include low-power IoT sensor nodes, battery-powered handheld instruments, LED lighting controls, automotive body controllers (non-safety), and consumer appliance user interfaces. The 14-pin PDIP package is preferred for prototyping, education, and through-hole designs where socket replacement and easy rework are valued.
When designing with this device, ensure decoupling capacitors are placed within 5 mm of VDD, route the ICSP/PGD/PGC lines with short traces, and validate the MCLR pull-up network for production reliability. For high-noise environments, place a 100 nF bypass close to each power pin.

Typical Applications
PIC16LF15324-I/P is suitable for 6 applications: Battery-Powered IoT Sensor Node, LED Lighting Controller, Consumer Appliance User Interface, Battery Charger Controller, Automotive Body Controller (Non-Safety), Handheld Test Instrument.
Battery-Powered IoT Sensor Node
The PIC16LF15324-I/P's 1.8V minimum supply and XLP nanoWatt sleep currents below 100 nA make it ideal for coin-cell IoT sensor nodes. Its 10-bit ADC with computation performs hardware-averaged conversions without waking the CPU, and the four Configurable Logic Cells can wake the part on a sensor threshold event without firmware overhead. Place the part between a CR2032 cell and a low-power radio, with a 10 kohm pull-up on MCLR and 100 nF decoupling within 5 mm of VDD. The 32 MHz core and 7 KB FLASH comfortably fit LoRaWAN or BLE node firmware.
Recommended
LED Lighting Controller
The PIC16LF15324-I/P drives LED strips via its four 10-bit PWM channels and the on-chip Complementary Waveform Generator (CWG), which produces dead-band-controlled complementary outputs ideal for half-bridge LED drivers. The 32 MHz instruction rate yields fine dimming granularity at 5 kHz PWM, well above the flicker-fusion threshold for human vision. Connect the CWG outputs through gate drivers to MOSFETs, and use the 5-bit DAC plus comparator for analog feedback of LED current. The 1.8V-3.6V supply range suits 2xAA battery LED fixtures.
Recommended
Consumer Appliance User Interface
The PIC16LF15324-I/P is well-suited for appliance UI boards handling capacitive touch, rotary encoder input, and segment-display driving. Its 12 I/Os and two MSSP peripherals (SPI/I2C) connect to segment LCD drivers, EEPROM, and capacitive touch ICs without external glue logic. The Core Independent Peripherals (CLCs) implement debouncing and encoder quadrature decoding entirely in hardware, keeping the core free for communication and UI updates. Operate from 3.3V via the on-board LDO, with brown-out reset enabling safe recovery from supply dropouts.
Recommended
Battery Charger Controller
The PIC16LF15324-I/P implements single-cell Li-Ion or NiMH charge profiles using its 10-bit ADC for voltage/current sense and 5-bit DAC for reference generation. The comparator provides hardware over-current protection that shuts the PWM duty cycle down without CPU latency. EUSART outputs drive charge-status LEDs or report telemetry to a host. The XLP low-power idle mode reduces quiescent draw below 50 uA, keeping the charger efficient in maintenance/float phases. Operate the part from the cell itself with a small LDO front-end.
Recommended
Automotive Body Controller (Non-Safety)
The PIC16LF15324-I/P, rated -40C to +85C industrial, fits non-safety automotive body applications such as interior lighting, mirror control, and seat-position memory where AEC-Q100 is not mandated. Its EUSART links to LIN slaves, the MSSP drives SPI-controlled actuator drivers, and the CLCs handle signal conditioning in hardware. The wide 1.8V-3.6V supply lets it run directly from a 3.3V regulator on the body harness. For safety-critical applications, select an AEC-Q100 qualified part from the same PIC16 family.
Recommended
Handheld Test Instrument
The PIC16LF15324-I/P is a fit for handheld DMMs and field test gear where 7 KB FLASH holds the measurement routine and 512 B SRAM buffers A/D samples. The on-chip 10-bit ADC samples signals up to ~100 ksps, suitable for slow analog measurements, and the comparator triggers capture without software latency. EUSART and MSSP ports expose USB-UART bridges and external EEPROM for data logging. The 14-PDIP package simplifies through-hole prototyping of front-panel PCBs and supports easy in-field IC replacement via sockets.

Key Differentiators
- Core Independent Peripherals (CIPs) reduce CPU load (vs PIC16LF15323-I/P)
- 1.8V operation enables coin-cell designs (vs PIC16F15324-I/P)
- Wider peripheral pin select (PPS) routing (vs PIC16LF1503-I/P)
Design Notes
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin (pin 14) and another on the AVdd rail if used, returning both to VSS. For coin-cell applications, add a 10 uF bulk capacitor near the MCU to handle transmit-current transients from a connected radio. Ensure MCLR has a 10 kohm pull-up to VDD for reliable reset during power-up brown-out events.
Route the ICSP/PGD (pin 2) and PGC (pin 3) traces as short as possible, keeping them away from high-frequency switching nodes such as PWM outputs or radio antenna traces. Add a 4.7 kohm pull-down on MCLR during ICSP programming to avoid false resets. For the CWG output (pin 12), keep the trace to the gate driver below 25 mm to limit ringing on the half-bridge node.
Do not assume the LF variant's 1.8V minimum applies to all peripherals - the ADC accuracy degrades below 2.0V. Always calibrate the ADC at the actual operating voltage using the FVR (Fixed Voltage Reference) module. When migrating from PIC16F15324-I/P, confirm that any 5V peripherals connected to I/O pins are tolerant of the LF variant's 3.6V VDD maximum. A common pitfall is forgetting to enable the PPS unlock sequence before remapping peripheral functions to different pins.
When using the MSSP in SPI mode at 32 MHz Fosc, the maximum reliable SCK rate is approximately 8 MHz (Fosc/4). For I2C, the MSSP supports Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) modes - verify that the pull-up resistors (typically 4.7 kohm for Fast, 2.2 kohm for Fast-Plus) match the bus capacitance and speed. Place the I2C pull-ups near the master device, not at the far end of the bus.
Compliance Information
RoHS and lead-free per Microchip product page. Not AEC-Q100 qualified; for automotive safety-critical applications, select a -Q1 qualified variant from the PIC16(L)F153XX family.
