PIC16F1824-I/JQ Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals on one die, enabling embedded control for appliances, sensors, and motor systems. Within the broader taxonomy, the PIC16F1824 belongs to the PIC16F1xxx enhanced mid-range 8-bit MCU family, which sits above the PIC10/12 baseline family and below the PIC18 8-bit extended family and the dsPIC/PIC32 16- and 32-bit families in Microchip's portfolio.
Key features include 12 I/O pins, 5 timers, 2 analog comparators, 4 PWM channels with independent time bases, a 10-bit ADC with up to 8 channels, an Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART), SPI and I2C (MSSP) peripherals, an on-chip 32kHz internal oscillator, and integrated mTouch capacitive-touch hardware. Sleep current is rated in the nanoampere range thanks to XLP technology, making the device suitable for battery-powered applications.
Architecturally, the PIC16F1824 uses Microchip's enhanced mid-range 8-bit core with 49 instructions, a 16-level hardware stack, automatic interrupt context saving, and a configurable instruction cycle. It supports in-circuit debugging via the 2-wire ICD interface without requiring a debug header, and is programmable through PICkit 3, MPLAB ICD 3, or MPLAB X IDE using the XC8 compiler.
Typical applications include low-power sensor nodes, capacitive touch user interfaces, LED lighting control, battery chargers, remote controls, small appliances, and consumer white-goods sub-assemblies. The wide 1.8V to 5.5V operating range simplifies designs that run from 2x AA cells, single Li-ion cells, or USB-derived rails.
When designing with this part, pay attention to the UQFN exposed-pad PCB layout - the pad must be soldered to the ground plane for thermal dissipation and electrical performance, and decoupling capacitors should be placed within 3 mm of the VDD pin to keep the ADC noise floor low.

Typical Applications
PIC16F1824-I/JQ is suitable for 6 applications: Battery-Powered Sensor Nodes, Capacitive Touch User Interfaces, LED Lighting Control, Small Appliance Control (White Goods), Remote Controls and IR Emitters, Industrial Sensor Signal Conditioning.
Battery-Powered Sensor Nodes
The PIC16F1824-I/JQ suits battery-powered sensor nodes because its XLP architecture delivers nanoamp-level sleep currents while still providing a 10-bit ADC and EUSART for sensor reads. The 1.8 V to 5.5 V operating range lets it run directly from two AA cells without a boost converter. The 32 kHz internal LF oscillator and 32 MHz internal HF oscillator eliminate external crystals, saving PCB area and BOM cost. The 7 KB Flash is sufficient for typical sensor-fusion plus LoRa/BLE UART forwarding firmware.
Recommended
Capacitive Touch User Interfaces
The PIC16F1824-I/JQ integrates Microchip's mTouch peripheral with CTMU and up to 8 capacitive-touch channels, enabling button grids, sliders, and proximity sensors without external touch ICs. The 10-bit ADC with 8 channels provides reliable touch measurement even in noisy environments. Combined with the 4 PWM channels, the device can drive both touch UI and LED backlight from a single MCU, reducing total BOM cost in appliance front panels.
Recommended
LED Lighting Control
The PIC16F1824-I/JQ provides 4 independent 10-bit PWM channels with programmable dead-band control, ideal for RGBW LED dimming and color mixing. The 32 MHz core and 49-instruction set enable smooth fades and animations. The EUSART and MSSP peripherals allow DMX512 or DALI lighting-protocol stack integration. The 1.8 V to 5.5 V range supports both battery-powered decorative LEDs and constant-current driver architectures.
Recommended
Small Appliance Control (White Goods)
The PIC16F1824-I/JQ is well suited for small appliance main control boards, including coffee makers, fans, and blenders. Its 12 I/O pins can drive triac gates, sense temperature via the 10-bit ADC, and read user buttons. The mTouch peripheral allows modern capacitive front-panel designs. Industrial temperature grade and wide operating voltage make it tolerant of rectified mains-derived rails with minimal external regulation.
Recommended
Remote Controls and IR Emitters
The PIC16F1824-I/JQ fits IR remote control designs thanks to its nanoamp sleep current (extending battery life to multiple years) and on-chip EUSART for IR modulation using external carrier transistors. The 7 KB Flash supports complex protocol stacks such as RC5, NEC, and custom bidirectional learning protocols. The internal 32 MHz oscillator provides accurate carrier timing without external crystals, keeping BOM minimal.
Recommended
Industrial Sensor Signal Conditioning
The PIC16F1824-I/JQ performs sensor signal conditioning in industrial applications by combining its 10-bit ADC, two analog comparators, and 5 timers for timing-critical filter routines. The MSSP peripheral supports I2C and SPI sensor interfacing for digital sensors, while the EUSART handles RS-485 communication via external transceivers. The 16-pin UQFN package keeps board footprint small for DIN-rail sensor modules.

Key Differentiators
- XLP ultra-low-power architecture with nanoamp sleep current (vs PIC16F1823-I/JQ)
- Industrial temperature grade optimized for cost-sensitive designs (vs PIC16F1824-E/JQ)
- mTouch capacitive sensing with integrated CTMU (vs PIC16F15325-E/JQ)
Design Notes
The 16-pin UQFN package includes an exposed thermal pad (EP) on pin 17 that MUST be soldered to a grounded copper pour on the PCB. Per Microchip datasheet 41419A, failing to solder the EP will cause thermal stress and potential reliability failures. The EP also serves as the primary ground return, so use multiple thermal vias under the pad to connect top and bottom ground planes.
Place a 100 nF decoupling capacitor within 3 mm of the VDD pin and a 10 uF bulk capacitor near the IC power pins. The PIC16F1824 has two ADC reference pins (VREF+ and VREF-) when used; route those separately with their own decoupling if an external reference is used. Estimated: at 32 MHz active current is approximately 5 mA, and sleep current can drop below 30 nA in retention mode.
Do not configure RA3 as a digital output - it is input-only and serves as MCLR by default. When using the internal oscillator, allow 1 ms startup time before code execution per datasheet 41419A. For capacitive touch designs, avoid placing LEDs or switching traces within 5 mm of the touch electrodes, as capacitive coupling can degrade touch sensitivity.
Route the ICSPDAT and ICSPCLK lines for in-circuit serial programming (ICSP) using Microchip's recommended 2-wire interface so that PICkit 3 or MPLAB ICD 3 can program the device without removing it from the board. Keep the ICSP traces away from high-frequency switching signals and add ESD protection diodes on the MCLR line for production environments.
Compliance Information
RoHS compliant per Microchip product page. The PIC16F1824-I/JQ is not AEC-Q100 qualified; for automotive designs, choose an AEC-Q100 qualified variant from Microchip's automotive portfolio. Lead-free and halogen-free per Microchip environmental compliance.
