PIC16LF18323-E/P Overview
An 8-bit microcontroller (MCU) is a small computer-on-a-chip containing a CPU, Flash program memory, RAM, EEPROM, and integrated peripherals such as ADC, DAC, timers, and communication interfaces. The PIC16LF18323 belongs to the PIC16 family -> 8-bit MCU -> microcontroller -> embedded IC -> integrated circuit hierarchy, and is part of Microchip's XLP sub-family optimized for ultra-low-power battery-operated designs.
Key features include a 10-bit ADC with 11 channels, a 5-bit DAC with 1 channel, Peripheral Pin Select (PPS) for flexible pin mapping of digital peripherals (CLC, CWG, CCP, PWM, communications), Core Independent Peripherals (CIPs), and the E suffix denoting the -40C to +125C extended operating temperature range. The 14-PDIP package supports through-hole assembly and breadboard prototyping.
The PIC16LF18323 uses a RISC architecture with a 14-bit instruction word optimized for deterministic interrupt latency and code density. The XLP technology delivers nanoWatt sleep currents in the order of tens of nanoamps, suitable for energy harvesting and battery applications that demand years of operation from a single coin cell.
Typical applications include battery-powered IoT sensor nodes, consumer remote controls, low-power wireless sensor endpoints, LED lighting controllers, and small appliances. The combination of integrated ADC, DAC, and Core Independent Peripherals enables smart sensor signal chains with minimal external components.
When designing with this device, ensure that the supply voltage range matches the operating frequency (2.5V minimum for 32MHz, 1.8V minimum for 16MHz), and apply decoupling capacitors (100nF + 10uF bulk) close to VDD. The PPS feature must be configured in firmware to map peripheral functions to physical pins.

Typical Applications
PIC16LF18323-E/P is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, Consumer Remote Controls, LED Lighting Controllers, Industrial Sensor Transmitters, Small Appliance Control Boards, Wearable Health Monitors.
Battery-Powered IoT Sensor Nodes
The PIC16LF18323-E/P fits battery-powered IoT sensor nodes due to its XLP nanoWatt sleep current (tens of nanoamps in deep sleep) and 1.8V minimum supply, which extends coin-cell battery life to multiple years. The 10-bit 11-channel ADC supports direct connection to temperature, humidity, and voltage sensors, while the on-chip DAC enables sensor excitation. Used between the battery and a wireless daughter module, the MCU performs periodic measurements, processes data with PPS-mapped peripherals, and wakes only on timer interrupts, achieving duty cycles below 0.1% and enabling multi-year operation from a single CR2032.
Recommended
Consumer Remote Controls
The PIC16LF18323-E/P is well suited for IR/RF remote controls thanks to its XLP sleep current (sub-100nA typical) and CWG (Complementary Waveform Generator) peripheral that produces IR carrier frequencies without CPU intervention. The 32MHz CPU enables fast wake-up from sleep (under 5us typical), so designers can implement low-duty-cycle transmission sequences. Used as the central MCU between push buttons and an IR LED driver, the part replaces mechanical scan matrices with CLC-based button debouncing, reducing BOM count and extending battery life to 5+ years from a single coin cell.
Recommended
LED Lighting Controllers
The PIC16LF18323-E/P fits LED lighting controllers because its 5-bit DAC and PWM peripherals enable direct analog or PWM dimming control without external driver ICs. The Core Independent Peripherals (CLC, CWG, CCP) offload lighting effects from the CPU, freeing the 32MHz core for protocol handling and user interface tasks. Used as the dimming controller in 4-channel constant-current LED drivers, the part produces smooth 0-100% brightness transitions with hardware-generated fades, while XLP modes allow standby power below 100nA when the lights are off, exceeding ENERGY STAR standby requirements for connected lighting products.
Recommended
Industrial Sensor Transmitters
The PIC16LF18323-E/P is appropriate for industrial 4-20mA sensor transmitters due to its -40C to +125C extended temperature range (E suffix) and integrated 10-bit ADC with 11 input channels. The 14-bit instruction word and RISC architecture deliver deterministic interrupt response under 200ns, critical for loop-powered transmitters with tight timing budgets. Used as the loop-powered MCU in 4-20mA temperature or pressure transmitters, the part digitizes sensor inputs, performs linearization, and modulates the loop current via the DAC, drawing under 3.5mA to remain within the 4mA zero-scale budget while supporting HART or wireless HART daughter modules.
Recommended
Small Appliance Control Boards
The PIC16LF18323-E/P fits small appliance control boards due to its Core Independent Peripherals (CLC, CWG) that handle motor control, triac firing, and user inputs without CPU intervention. The 32MHz CPU and PPS flexibility support multiple communication protocols including UART, I2C, and SPI for interfacing with sensors, displays, and Wi-Fi/BLE modules. Used as the main MCU in coffee machines, blenders, or air purifiers, the part manages triac-based heater control, BLDC fan commutation via CWG, and capacitive touch sensing via CTMU, reducing PCB area by replacing several dedicated ICs with a single 14-PDIP device.
Recommended
Wearable Health Monitors
The PIC16LF18323-E/P suits wearable health monitors thanks to its XLP deep-sleep currents below 50nA and 1.8V operation, which allow coin-cell-powered wearables to operate for weeks per charge. The 10-bit ADC with internal voltage reference and the 5-bit DAC enable accurate biosignal acquisition (heart rate, SpO2 red/IR LED current control). Used as the sensor interface between a Li-ion battery and a BLE SoC, the MCU handles biosensor sampling, basic filtering, and BLE event triggering, while its small 14-PDIP footprint supports compact wearable form factors in fitness bands and medical patches.

Key Differentiators
- Extended temperature grade with XLP low-power silicon (vs PIC16LF18323-I/P)
- Upgraded memory and PPS flexibility (vs PIC16LF18313-E/P)
- DAC and CWG peripherals absent in legacy parts (vs PIC16F1823-E/P)
Design Notes
Apply a 100nF decoupling capacitor as close as possible to the VDD pin (pin 1 in 14-PDIP) with a 10uF bulk capacitor on the supply rail. For battery applications using XLP modes, ensure the MCLR pull-up is disabled in the configuration bits to avoid continuous leakage current. The PIC16LF18323-E/P nanoWatt sleep current of approximately 20nA is achievable only with all peripherals disabled and the watchdog timer turned off, so verify sleep power in your actual code before committing to battery life calculations.
For the 14-PDIP package, route VDD and VSS on adjacent pins (1 and 14) to enable tight bypass capacitor placement. Keep analog reference (if used) traces short and away from digital switching lines to avoid ADC noise coupling. If using the ICSP programming interface, reserve RA0/RA1 for ICSP data/clock to allow in-circuit programming without removing the MCU from the board.
Do not assume all PPS-mappable peripherals can be assigned to any pin - verify against the PPS input/output selection tables in the datasheet. The PPS unlock sequence (PPSLOCKED bit) must be cleared before changing PPS assignments. When migrating from PIC16F1823 to PIC16LF18323, verify that the DAC output pin assignment matches your PCB layout - the LF18323 added DAC functionality that may require routing changes if not originally planned.
Compliance Information
RoHS and lead-free compliant per Microchip product page. Extended temperature grade (-40C to +125C) suitable for industrial but not AEC-Q100 automotive qualified.
