PIC16F18424T-I/JQ Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (typically flash), working memory (RAM), data EEPROM, and a rich set of peripherals including timers, communication interfaces, and analog blocks. The PIC16F18424 belongs to the 8-bit PIC16 family of low-pin-count MCUs, sitting within the broader PIC microcontroller -> Microchip 8-bit product line -> embedded controller -> semiconductor hierarchy. It targets general-purpose and battery-powered applications that need strong analog integration without sacrificing low power.
Key features include a 12-bit ADC with Computation (ADCC), two 10-bit PWMs, a 5-bit DAC, a comparator, Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), and serial interfaces including EUSART, SPI, and I2C. The XLP technology delivers typical sleep currents in the nanoamp range and active currents well under 1 mA/MIPS, making it suitable for energy-harvesting and always-on designs. It also includes an integrated temperature indicator and supports the Functional Safety (FuSa) hardware diagnostic library required by IEC 61508 SIL-2 capable applications. The wide 2.3 V to 5.5 V supply range further broadens its deployment flexibility across 3.3 V and 5 V rails.
Typical applications include low-power IoT sensor nodes, home automation controllers, battery management ICs, LED lighting controllers, and small industrial control modules. Its compact 4x4 mm UQFN footprint is also ideal for space-constrained wearables and consumer gadgets.
When designing, ensure the decoupling capacitor is placed within a few millimetres of the VDD pin and that the MCLR pin is pulled high through a proper resistor to guarantee clean reset behavior. Compared with the 20-pin PIC16F18444, this 16-pin variant sacrifices a few I/O lines and a second EUSART for its smaller footprint.

Typical Applications
PIC16F18424T-I/JQ is suitable for 6 applications: Battery-Powered IoT Sensor Node, Home Automation Lighting Controller, Wearable Health Monitor, Industrial Sensor Transmitter (4-20 mA / IO-Link), Small Appliance Control Board, Automotive Body Electronics (Non-Safety).
Battery-Powered IoT Sensor Node
The PIC16F18424T-I/JQ is ideal for battery-powered IoT sensor nodes because its XLP technology pushes quiescent current into the nanoamp range while the 12-bit ADCC, integrated temperature indicator, and EUSART/SPI/I2C ports enable direct connection to sensors and sub-GHz radios. With 7 KB of flash supporting the FuSa diagnostic library and 512 B of SRAM for sensor fusion, the device fits on a CR2032 coin cell for years. The 16-UQFN 4x4 mm footprint lets designers place the MCU under a sensor socket, minimizing the PCB envelope and reducing BOM cost for sub-$10 wireless nodes.
Recommended
Home Automation Lighting Controller
For LED dimming and color-mixing controllers, the PIC16F18424T-I/JQ delivers two 10-bit PWM channels, the Complementary Waveform Generator (CWG), and a 5-bit DAC that together drive constant-current LED strings with smooth fading and zero-crossing detection. The 32 MHz core handles DMX-512, DALI, and Casambi-style protocols via the EUSART, while the CLCs implement hardware PWM dead-time without CPU overhead. Operating from 2.3-5.5 V, the device pairs with both 3.3 V wireless modules and 5 V LED driver rails, eliminating level shifters and shrinking the BOM.
Recommended
Wearable Health Monitor
The PIC16F18424T-I/JQ fits wearable health monitors where board real estate is measured in square millimetres. Its 4x4 mm UQFN footprint, 32 MHz CPU, and 12-bit ADCC provide accurate photoplethysmography (PPG) and bio-impedance sampling, while the 256 B EEPROM stores calibration data across power cycles. The XLP sleep mode with full SRAM retention lets the device wake on a sensor interrupt, perform a measurement, transmit via SPI or I2C to a BLE radio, and return to deep sleep at microamp currents. The industrial -40 to +85 C temperature range supports skin-contact and ambient sensing duties.
Recommended
Industrial Sensor Transmitter (4-20 mA / IO-Link)
The PIC16F18424T-I/JQ is suited to industrial 4-20 mA and IO-Link sensor transmitters thanks to its Functional Safety (FuSa) IEC 61508 SIL-2 capable diagnostic library and 2.3-5.5 V supply that accepts 24 V loops with simple regulation. The 12-bit ADCC, 5-bit DAC, and analog comparator deliver ratiometric sensor conditioning, while the CWG and PWM blocks generate excitation signals for RTD and bridge sensors. With 7 KB of flash the MCU runs IO-Link stack firmware plus the FuSa self-test suite on a single die.
Recommended
Small Appliance Control Board
Coffee makers, blenders, and countertop ovens benefit from the PIC16F18424T-I/JQ's combination of 2x PWMs, the CWG, the CLC logic cells, and the rich communication peripherals. The 32 MHz core handles BLDC commutation tables in firmware, while the dedicated hardware peripherals generate dead-band timings without CPU intervention. With 7 KB of flash and 256 B EEPROM the MCU stores user presets and life-cycle counters. Operating from 2.3-5.5 V lets it share a common rail with rectified-mains-derived 5 V supplies.
Recommended
Automotive Body Electronics (Non-Safety)
For non-safety automotive body applications such as interior lighting, HVAC flap control, and accessory modules, the PIC16F18424T-I/JQ provides the same die qualified for the AEC-Q100 automotive grade as its Q-graded sibling, while the industrial -40 to +85 C temperature grade fits cabin environments. Its 16-UQFN footprint, EUSART/LIN-capable UART, and PWM channels are well-matched to small body controllers, and the XLP modes help meet quiescent-current budgets of <100 uA on parked-vehicle networks.

Key Differentiators
- Smallest form-factor PIC16F184xx MCU with FuSa library (vs PIC16F18444T-I/JQ)
- Higher flash density than predecessor PIC16F18324 (vs PIC16F18324T-I/JQ)
- Lower-voltage variant available for ultra-low-power designs (vs PIC16LF18424T-I/JQ)
Design Notes
Place a 100 nF decoupling capacitor within 2 mm of the VDD pin (pin 15) and a bulk 1 uF to 10 uF capacitor on the same node. The XLP architecture is sensitive to supply ripple during sleep-to-wake transitions, so keep the VDD trace short and wide. For battery-powered designs operating below 3 V, choose the PIC16LF18424T-I/JQ to extend usable runtime.
The 16-UQFN 4x4 mm package exposes the central thermal pad on the underside. Stencil-print a 4x4 via array (0.3 mm drill, 0.5 mm pitch) into the central pad to dissipate the chip's heat and provide a low-inductance ground path. Reflow profile should follow JEDEC J-STD-020 with peak temperature below 260 C, and PCB land pattern should follow IPC-7351 QFN guidelines for 0.5 mm pitch.
Do not leave the MCLR pin floating; tie it to VDD through a 10 kohm resistor to guarantee a clean reset during power-up. When programming via ICSP, ensure the PGC/PGD lines have 4.7 kohm pull-ups and that no low-impedance load is attached during in-circuit programming. Avoid switching the internal FOSC source without first clearing the OSCCON SPLLEN bit, or the PLL can fail to lock and stall the CPU.
Keep ADC traces short and surrounded by a ground pour to minimise digital noise coupling into the 12-bit ADCC. For sensitive analog measurements, average at least 16 samples using the ADCC's hardware accumulator to suppress mains-frequency interference. Place the analog reference capacitor within 5 mm of the Vref+ pin to keep the reference stable across temperature.
Compliance Information
RoHS compliant per onlinecomponents.com product listing. AEC-Q100 grade is not qualified for this specific I-temp industrial variant; Microchip offers a separate E-temp automotive sibling on the PIC16F18424 family page.
