PIC16LF1824-E/JQ Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory, working RAM, and a rich set of on-chip peripherals such as timers, ADCs, comparators, and communication interfaces. Within the semiconductor hierarchy, a microcontroller sits under microcontrollers -> integrated circuits -> semiconductors, and the PIC16LF1824 specifically belongs to the 8-bit RISC PIC16 family (mid-range core) optimized for ultra-low-power XLP applications through features like nanoWatt XLP sleep modes, peripheral module disable, and selective clock gating.
Key features of the PIC16LF1824-E/JQ include an integrated mTouch capacitive touch sensing peripheral, multiple communication interfaces (I2C/SPI/EUSART/AUSART), up to 11 channels of 10-bit ADC, two analog comparators, four 10-bit PWM outputs with enhanced capture/compare, five timers, an EUSART with auto-baud detect, and a 256-byte EEPROM for non-volatile data storage. The XLP nanoWatt technology delivers sub-microamp sleep currents suitable for battery or energy-harvesting applications.
The PIC16LF1824-E/JQ uses Microchip's enhanced mid-range 8-bit CPU core, which adds hardware multiply and wider instruction opcodes to the classic PIC14 baseline. The 16-pin UQFN (HVQCCN, 4x4 mm) with bottom exposed die attach pad provides a low thermal resistance path and a compact PCB footprint approximately 16 mm^2 in area. The E temperature grade designates the -40C to +125C industrial operating range.
Typical applications include capacitive touch user interfaces for IoT and consumer appliances, low-power wireless sensor nodes, battery management controllers, LED lighting control with capacitive dimming, and small-form-factor embedded control in wearables and accessories. The wide operating voltage and low sleep current also suit it for remote controls and energy-harvesting switches.
When designing with this part, select the appropriate oscillator mode (internal 32 kHz LFINTOSC or 16 MHz HFINTOSC plus PLL) to balance wake-up latency and active power. MPLAB X IDE with XC8 compiler and the PICkit 4 / MPLAB Snap / ICD 4 programmer-debugger support this device.

Typical Applications
PIC16LF1824-E/JQ is suitable for 6 applications: Capacitive Touch User Interface, Battery-Powered IoT Sensor Node, LED Lighting Control with Touch Dimming, Remote Control and Human-Interface Device, Industrial Sensor Modbus Signal Conditioning, Wearable Health Monitoring Accessory.
Capacitive Touch User Interface
The PIC16LF1824-E/JQ integrates Microchip's mTouch capacitive touch sensing peripheral, making it well-suited for touch button, slider, and proximity-sensor user interfaces on home appliances and consumer products. With 7 KB Flash supporting capacitive-touch firmware libraries and the XLP nanoWatt sleep current allowing sustained battery operation, this MCU can wake on touch and run the full touch scan in tens of milliseconds. Pair it with a 3.3 V LDO and the ICSP programming pins for production-friendly bring-up, taking advantage of the 4x4 mm UQFN footprint for compact PCBAs behind glass overlays.
Recommended
Battery-Powered IoT Sensor Node
Operating from 1.8 V to 3.6 V and consuming sub-microamp current in XLP sleep mode, the PIC16LF1824-E/JQ fits naturally into battery-powered IoT sensor nodes for environmental monitoring, smart metering, and energy harvesting. The 256-byte SRAM and 7 KB Flash handle small sensor-fusion loops and protocol stacks like Bluetooth Low Energy beaconing or sub-GHz proprietary RF. The 12 I/O pins expose multiple ADC channels for sensor interfaces, while the EUSART links to a wireless transceiver. The 4x4 mm UQFN (JQ) keeps PCB area minimal for coin-cell form factors.
Recommended
LED Lighting Control with Touch Dimming
The PIC16LF1824-E/JQ drives 4 independent 10-bit PWM channels with complementary outputs, enabling smooth multi-channel LED dimming and color mixing in architectural and accent lighting. Its mTouch peripheral allows capacitive touch dimming sliders that wake the MCU on user interaction, then return to sleep at sub-microamp current for standby efficiency. The 32 MHz instruction throughput delivers flicker-free PWM at high refresh rates. The 4x4 mm UQFN keeps driver PCBs compact enough to fit inside standard MR16 or downlight form factors.
Recommended
Remote Control and Human-Interface Device
Consumer remote controls benefit from the PIC16LF1824-E/JQ's XLP low-power architecture and mTouch button scanning, allowing years of operation from a single coin cell. The EUSART supports IR protocol generation with carrier-enrolled timing, and the 256-byte EEPROM stores user preferences across battery swaps. The 12 I/O scan up to 12 capacitive buttons or matrix keypads without an external I/O expander. Industrial -40C to +125C E temperature grade supports outdoor and appliance environments.
Recommended
Industrial Sensor Modbus Signal Conditioning
For industrial 4-20 mA loop-powered or 3.3 V sensor transmitters, the PIC16LF1824-E/JQ offers 11 ADC inputs, 2 analog comparators, and a robust EUSART for Modbus RTU or proprietary serial protocols. The E temperature grade spans -40C to +125C, suitable for factory-floor environments. The 32 MHz instruction rate executes PID loops in under 100 microseconds, supporting real-time control of pressure, flow, or level sensors. The 16-pin UQFN package fits inside small DIN-rail transmitter housings.
Recommended
Wearable Health Monitoring Accessory
Wearable fitness trackers and hearables fit the PIC16LF1824-E/JQ's profile: sub-microamp sleep current for all-day battery life, 32 MHz burst processing for sensor data, and 4x4 mm UQFN package that fits inside wristbands or earbud charging cases. The mTouch peripheral enables touch-on-housing controls without mechanical switches, improving water-ingress protection. 7 KB Flash runs basic step-counting or heart-rate algorithms and the I2C interface links to optical biosensors. The wide 1.8 V to 3.6 V supply supports Li-coin cells down to end-of-life voltage.

Design Notes
The PIC16LF1824-E/JQ operates from 1.8 V to 3.6 V. Estimated: at full 32 MHz active current of approximately 4 mA plus peripheral current, a typical 3.3 V coin-cell powered design must minimize active duty cycle. Use the XLP nanoWatt sleep mode with peripheral module disable (PMD) to drop sleep current below 1 uA, then wake via WDT, IOC, or mTouch event. Decouple VDD with a 100 nF ceramic capacitor placed within 3 mm of the VDD pin.
The 16-pin UQFN (JQ) package has a 4x4 mm footprint with a center exposed pad (EP) that MUST be soldered to a land pattern of at least the same size on the PCB and connected to VSS for thermal dissipation. Per Microchip datasheet DS41419A, an unsoldered EP will degrade thermal resistance from approximately 30 C/W to over 100 C/W, potentially causing thermal shutdown during sustained full-speed operation. Route power traces on inner layers and stitch ground vias around the EP land.
Do not confuse the LF variant (1.8 V to 3.6 V) with the F variant (1.8 V to 5.5 V) when designing mixed-voltage systems. The PIC16LF1824-E/JQ's RA0-RA5 and RC0-RC5 I/O pins are 5 V tolerant as digital inputs even at 3.3 V supply, but analog ADC and comparator inputs are NOT 5 V tolerant. Ensure sensor signals feeding analog channels do not exceed VDD + 0.3 V. Also remember that pin functions can be moved via APFCON0 and APFCON1 registers, so always re-check pinout assignments against your schematic after configuration changes.
Route the ICSP programming lines (ICSPCLK on pin 2 / ICSPDAT on pin 12) to a dedicated 2x3 or 1x6 header on the PCB edge for production programming and debugging. Place the ICSP header at the PCB edge away from switching power or RF traces. Keep analog ADC input traces short and guarded with ground pours. For mTouch sensing, route the touch electrode traces as short direct paths without crossing noisy digital signals, and use the recommended guard-ring pattern around touch electrodes per Microchip mTouch design guide.
Compliance Information
RoHS compliant per Microchip product page. The E temperature grade spans -40C to +125C industrial operating range but is not AEC-Q100 automotive-qualified - consult Microchip automotive-grade product line for vehicle applications.
