PIC16F18424-E/JQ Overview
A microcontroller (MCU) is a single-chip computer that combines a CPU core, non-volatile program memory (typically Flash), working RAM, and a rich set of peripherals such as timers, ADCs, communication interfaces, and GPIO. PIC microcontrollers use a RISC architecture optimized for deterministic instruction execution and very low power consumption. The PIC16F18424 belongs to the enhanced mid-range 8-bit core family and adds CIPs that offload tasks like waveform generation, signal conditioning, and complementary output control without CPU intervention. Positioned in the hierarchy MCU -> microcontroller -> embedded controller -> semiconductor, this device targets battery-powered and space-constrained designs.
Key specifications include a 12-bit ADC with Computation (ADCC), a 5-bit DAC, two PWMs, a Complementary Waveform Generator (CWG), an EUSART plus SPI/I2C peripherals, and Functional Safety (FuSa) support for safety-critical applications. The integrated Peripheral Pin Select (PPS) allows flexible remapping of digital peripherals to any I/O pin, simplifying PCB layout in small 16-pin packages.
The 16-UQFN package measures just 4x4 mm, suiting wearables, sensor nodes, and handheld instruments. The XLP Sleep mode draws under 50 nA typical, and the device offers multiple low-power operating modes such as Doze, Idle, and Sleep with peripheral operation using the LFINTOSC or the 16 MHz HFINTOSC.
Typical applications include IoT sensor nodes, battery-powered environmental monitors, LED lighting controllers, automotive body electronics, home appliance user interfaces, and low-power industrial sensor transmitters. Functional Safety support makes it a fit for auxiliary safety subsystems.
When designing, place a 0.1 µF decoupling capacitor close to VDD and ensure the ICSP™/ICD pins are accessible for in-circuit programming and debug. Use PPS to route peripherals to convenient pins, and select the appropriate oscillator mode to balance wake-up time against quiescent current.

Typical Applications
PIC16F18424-E/JQ is suitable for 6 applications: Battery-Powered IoT Sensor Node, Automotive Body Electronics, LED Lighting Controller, Home Appliance User Interface, Industrial Sensor Transmitter, Consumer Remote Control / HMI.
Battery-Powered IoT Sensor Node
The PIC16F18424-E/JQ is well suited to battery-powered IoT sensor nodes thanks to its XLP Sleep mode drawing under 50 nA typical, 32 MHz HFINTOSC for fast wake-and-measure cycles, and 12-bit ADCC for direct sensor digitization. With 7 KB Flash and 512 B RAM, firmware can implement sensor calibration, sleep scheduling, and EUSART/SPI/I2C reporting without external components. The 4x4 mm 16-UQFN package leaves room for coin-cell holders and antenna keep-out on space-constrained sensor PCBs.
Recommended
Automotive Body Electronics
The PIC16F18424-E/JQ is qualified for the -40 °C to +125 °C extended automotive temperature range and offers Functional Safety (FuSa) support, making it appropriate for body-electronics subsystems such as lighting controllers, mirror adjusters, and seat modules. Its Complementary Waveform Generator (CWG) drives half-bridges for LED dimming and small motor control without CPU overhead, while PPS allows flexible pin routing inside tight 16-pin PCBAs. The 2.5 V to 5.5 V supply range aligns with automotive 5 V rails directly.
Recommended
LED Lighting Controller
For LED lighting and architectural illumination, the PIC16F18424-E/JQ delivers two 10-bit PWM channels plus a Complementary Waveform Generator (CWG) for driving half-bridge FETs with programmable dead-time. The 12-bit ADCC can sample light sensors for closed-loop brightness control, while EUSART/SPI/I2C peripherals interface with DMX, DALI, or wireless modules. The 16-UQFN package and 32 MHz clock allow compact form-factor drivers for bulbs, strips, and downlights.

Home Appliance User Interface
In washing machines, coffee makers, and kitchen appliances, the PIC16F18424-E/JQ handles capacitive touch sensing, LED indicators, and rotary encoder input through its CWG and comparators. The 7 KB Flash accommodates state-machine firmware for user-interface logic, and 512 B RAM is sufficient for keypad buffering and display refresh. PPS enables optimal pin assignment for front-panel PCBs with mixed signal and power domains.

Industrial Sensor Transmitter
The PIC16F18424-E/JQ's 12-bit ADCC with computation integrates averaging and oversampling for 4-20 mA loop and bridge-sensor front ends, while the 5-bit DAC supports calibration voltage generation. The extended -40 °C to +125 °C range suits outdoor industrial installations, and the EUSART provides RS-485 connectivity with external transceivers. XLP Sleep mode allows multi-year battery life on remote telemetry units.
Recommended
Consumer Remote Control / HMI
The PIC16F18424-E/JQ integrates all peripherals required for low-cost infrared remote controls and simple human-machine interfaces: comparators for IR receiver signal conditioning, timers for carrier generation, and PWMs for backlight or buzzer drive. With 7 KB Flash it supports multiple protocol stacks, and XLP Sleep under 50 nA extends coin-cell life across years of standby. The 4x4 mm UQFN fits behind membrane keypads in handheld form factors.

Key Differentiators
- Functional Safety (FuSa) support in 16-pin UQFN (vs PIC16F18324-E/JQ)
- 12-bit ADCC with computation hardware (vs PIC16F1825-I/JQ)
- Upward migration to PIC16F18426 in same footprint (vs PIC16F18426-E/JQ)
Design Notes
Place a 0.1 µF decoupling capacitor as close as possible to the VDD pin (pin 16) with a trace length under 5 mm. Add a bulk 1-10 µF capacitor near the regulator output. In battery designs, use XLP Sleep mode with HFINTOSC disabled; wake via Watchdog Timer or IOC to minimize Sleep current. Estimated Sleep current based on PIC16F184xx family typical specifications is under 50 nA with RTC running.
The 16-UQFN (4x4 mm) has an exposed thermal pad that should be soldered to a copper pad tied to VSS for mechanical strength and thermal dissipation. Route ICSPCLK and ICSPDAT (RA0/RA1) to a 2x3 0.1 inch header or pogo-pad footprint for in-circuit programming and debug. Use PPS to assign peripherals to convenient pins and keep high-speed traces short.
Do not confuse PIC16F18424 with PIC16LF18424: the F variant operates 2.5 V to 5.5 V, while the LF variant is 1.8 V to 3.6 V. MCLR on RA3 is enabled by default in configuration bits; if used as GPIO, disable MCLR via CONFIG3. PPS must be unlocked before remapping; failing to do so produces silent peripheral failures. Always verify configuration bits in MPLAB X before programming production parts.
Compliance Information
PIC16F18424-E/JQ is RoHS compliant and lead-free per Microchip product environmental compliance data. The 'E' temperature grade covers -40 C to +125 C extended automotive range; AEC-Q100 qualification status is part-specific - verify with Microchip for the exact ordering code.
