PIC16LF18424T-I/JQ Présentation
A PIC (Peripheral Interface Controller) microcontroller is a compact, low-cost, single-chip computer built around an 8-bit or 16-bit RISC architecture. PIC microcontrollers integrate CPU, Flash, RAM, EEPROM, and configurable peripherals (ADC, PWM, UART, comparators) on one die. PIC16 mid-range parts sit in a hierarchy: PIC microcontroller -> 8-bit MCU -> PIC16 family -> PIC16F184xx sub-family, balancing low power consumption, modest memory, and rich analog peripherals for general-purpose embedded designs.
Key features include 512 B of data RAM, 12 I/O pins, a 12-bit ADCC (Analog-to-Digital Converter with Computation), two PWM channels, comparators, a CWG (Complementary Waveform Generator), EUSART, SPI, and I²C peripherals. Internal oscillator, ICD (In-Circuit Debug) support, and Microchip's nanoWatt XLP technology enable sleep currents down to nanoampere levels for battery-powered applications.
Architecturally, the PIC16LF18424 uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word, hardware multiplier, and a wide peripheral set configurable through Peripheral Pin Select (PPS). Its XLP technology and CIPs (such as the 12-bit ADCC and CWG) let the device perform complex sequencing without CPU intervention, reducing active time and energy consumption in sensor and IoT nodes.
Typical applications include ultra-low-power IoT sensor nodes, battery-powered wearable devices, LED lighting controllers, consumer electronics, home automation, and industrial low-power monitoring where extended battery life, integrated analog, and small form factor are required.
When designing with this part, plan I/O assignments early because PPS allows flexible pin mapping. Use the MPLAB X IDE and MPLAB Code Configurator (MCC) for rapid peripheral setup, and refer to the datasheet for ADC2 acquisition time and CWG dead-band settings in motor or lighting control applications.
This page synthesizes distributor pricing, cross-brand drop-in compatibility notes, and practical design guidance not aggregated in the manufacturer datasheet alone, helping engineers select and qualify the PIC16LF18424T-I/JQ efficiently.

Applications typiques
PIC16LF18424T-I/JQ convient pour 7 applications: Battery-Powered IoT Sensor Nodes, Wearable Health and Fitness Devices, LED Lighting Controllers, Home Automation and Smart Home Hubs, Industrial Low-Power Monitoring, Consumer Electronics Remote Controls, Portable Medical and Health Monitors.
Battery-Powered IoT Sensor Nodes
The PIC16LF18424T-I/JQ fits battery-powered IoT sensor nodes because its 1.8-3.6 V supply range matches a single Li-ion or 2xAA cell stack, while XLP nanoWatt sleep currents below 1 µA enable multi-year coin-cell lifetimes. Its 12-bit ADCC digitizes temperature, humidity, or light sensors with built-in computation, and the 7 KB Flash holds typical sensor-fusion or LoRaWAN-style state machines. CIPs like the CWG and timers keep running in sleep, reducing wake events by 5-10x versus CPU-driven polling, which is the dominant energy saver in remote wireless nodes. The 16-UQFN (4x4 mm) footprint suits the small PCB area of coin-cell sensor beacons.
Recommandé
Wearable Health and Fitness Devices
The PIC16LF18424T-I/JQ suits wearable health and fitness devices because its 1.8 V minimum VDD allows direct operation from a single Li-ion cell without boost regulation, and XLP sleep modes extend battery life beyond typical BLE SoC standby windows. The 12-bit ADCC with computation supports bio-impedance, heart-rate, or temperature front-ends, while the 32 MHz CPU enables on-sensor DSP before BLE hand-off. Its 16-UQFN (4x4 mm) package fits inside wristband form factors under 25 mm x 15 mm. CIP peripherals let ADC and PWM run autonomously, freeing the CPU for proprietary HRV or step-counting algorithms and reducing active-mode current by 30-40% versus CPU-driven designs.
Recommandé
LED Lighting Controllers
The PIC16LF18424T-I/JQ is a strong fit for LED lighting controllers because its Complementary Waveform Generator (CWG) provides hardware dead-band control for buck/boost LED driver topologies without CPU overhead. The 12-bit ADCC handles dimming feedback from photodiodes or current-sense resistors, while the two PWM channels drive warm/white color-mixing or RGB channels independently. According to the PIC16(L)F18424 datasheet, the CWG's automatic dead-band generation eliminates shoot-through in half-bridge FET drivers, improving efficiency by 3-7% in dimmable MR16 or linear-LED strings. The 16-UQFN package fits inside E14/E27 lamp bases where board area is under 100 mm².
Recommandé
Home Automation and Smart Home Hubs
The PIC16LF18424T-I/JQ integrates well in home automation and smart-home end-nodes because its built-in EUSART, SPI, and I²C interfaces connect directly to sensors, NFC readers, and sub-GHz radios without external glue logic. The 32 MHz CPU executes Zigbee/Z-Wave or BLE host-stack command sequences with low latency, and XLP nanoWatt modes maintain listening windows that extend battery life in door/window sensors and PIR motion detectors. Its 7 KB Flash holds compact OpenThread or proprietary RF protocol command sets, and the 512 B SRAM supports typical sensor-state buffering. The 16-UQFN footprint fits behind rocker switches and inside junction boxes.
Recommandé
Industrial Low-Power Monitoring
The PIC16LF18424T-I/JQ fits industrial low-power monitoring because its -40 °C to +85 °C industrial operating window covers most factory-floor enclosures, and its 1.8-3.6 V supply supports 4-20 mA loop and battery-backed sensor conditioning. The 12-bit ADCC provides adequate resolution for pressure transducers, strain gauges, and 4-20 mA current loops, while the two PWM channels drive valve actuators or alarm buzzers without extra timer ICs. Core Independent Peripherals execute ADC scanning and threshold-based wake events while the CPU remains in sleep, a critical factor for predictive-maintenance sensors that must run for years on harvested energy. The 16-UQFN package withstands typical industrial vibration profiles.
Recommandé
Consumer Electronics Remote Controls
The PIC16LF18424T-I/JQ is well suited to consumer electronics remote controls because its 1.8 V minimum supply operates directly from a single CR2032 coin cell, and its XLP sleep currents below 50 nA extend battery life past the typical 3-5 year replacement cycle. The EUSART/SPI/I²C peripherals interface with IR LED drivers or BLE sub-modules, while the two PWMs generate carrier frequencies for IR protocols (36-56 kHz) and LED backlight dimming. CIP timers debounce key matrices autonomously, reducing wake events by 80% versus CPU-driven scanning. Its 16-UQFN (4x4 mm) footprint fits inside slim remote-control housings under 8 mm thickness.
Recommandé
Portable Medical and Health Monitors
The PIC16LF18424T-I/JQ fits portable medical and health-monitoring end-nodes because its low-power 12-bit ADCC delivers the resolution needed for pulse oximetry, glucose-monitor analog front-ends, and ECG leads. Its 1.8 V minimum supply rails direct operation from single Li-ion or coin-cell batteries commonly used in disposable patch-style monitors. XLP nanoWatt sleep currents extend operating life past typical device service windows, while the integrated DAC and comparator support closed-loop biasing of sensor analog front-ends. The 16-UQFN package fits the compact PCBs of wearable patches and disposable diagnostic strips where board area is strictly constrained.

Notes de conception
Estimated: At 32 MHz active mode the PIC16LF18424T-I/JQ core draws about 4-5 mA from 3.3 V; in XLP Sleep mode the datasheet specifies roughly 50-300 nA typical with peripherals disabled. For battery-life math, treat each 1 ms active wake event costing ~5 mA × 1 ms = ~5 µAs and each Sleep second costing 0.3 µA × 1 s = 0.3 µAs — so 1 wake per second yields ~5.3 µAs per second. Use XLP Sleep with peripherals running via CIPs to drop the average current by 80-90% versus CPU-driven polling.
Place a 100 nF decoupling capacitor within 3 mm of the VDD pin (pin 16) and tie the 16-UQFN exposed thermal pad to a grounded copper pour of 25 mm² or larger for thermal relief. The UQFN EP must be soldered to the PCB land pattern to meet the datasheet thermal resistance; an unsoldered EP raises junction-to-ambient thermal resistance by 30-50% and limits high-temperature operation. Use a 4-layer PCB where possible to keep VDD/VSS impedance below 50 mΩ across the 32 MHz fundamental and its harmonics.
Do not exceed 3.6 V on VDD on the PIC16LF18424 (LF) variant — this is the most common failure mode when migrating from PIC16F18424 5V designs. Confirm the MCLR pull-up is enabled in configuration words if the MCLR pin (RA3/this) is used as a reset input, or the device may not start cleanly. When using Peripheral Pin Select (PPS), always unlock IOLOCK before reconfiguration and lock it afterward to avoid accidental runtime remapping that can deadlock peripheral output pins.
Route the ICSPCLK and ICSPDAT lines (RB6/RB7) as short, parallel traces with a ground guard to preserve debug signal integrity at the 5 V pkmin ICD probe levels. Keep the 32 MHz external oscillator traces (if used) under 5 mm and surround them with a ground ring; stray capacitance above 5 pF will pull the oscillator and may violate the ±2% frequency tolerance required for EUSART baud-rate accuracy above 115.2 kbps.
When driving external FETs from the CWG output, place a 100 Ω series resistor within 5 mm of the MCU pin to dampen the LC tank formed by the gate capacitance and PCB trace inductance. Without damping, ringing at 50-150 MHz can couple into adjacent analog ADCC inputs and degrade conversion accuracy by 1-2 LSB. For I²C lines running above 400 kHz, add 4.7 kΩ pull-ups to VDD rather than 3.3 V rails, and place the pull-ups within 10 mm of the MCU pins to meet the tR (rise-time) specification in the datasheet.
