PIC16LF1824T-I/JQ Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, Flash program memory, RAM, EEPROM, peripherals, and interrupt logic on one die. Within the embedded hierarchy it belongs to microcontrollers, then to microcontrollers and processors, and finally to semiconductors. The 'LF' prefix denotes the nanoWatt XLP extreme-low-power family optimized for battery-backed and energy-harvesting designs.
Key features include nanoWatt XLP technology with sub-uA sleep currents, an integrated 32 MHz internal oscillator with 4x PLL option, 12-channel 10-bit ADC with computation, mTouch capacitive sensing support, multiple communication peripherals (I2C/SPI/EUSART), and on-chip temperature indicator. The 14-pin UQFN (JQ) package is only 4 mm square, ideal for space-constrained designs.
The enhanced mid-range core adds hardware multiply and larger stack depth over baseline PIC16, while CWG (Complementary Waveform Generator) and DSM (Data Signal Modulator) peripherals enable advanced motor-drive and signal-modulation tasks. The 10-bit ADC with ADC Computation (ADC^2) reduces CPU load by averaging and threshold-comparing in hardware.
Typical applications include low-power IoT sensor nodes, wearable health monitors, remote controls, battery-powered HVAC sensors, LED lighting controllers, and consumer electronics user interfaces. The wide voltage range makes it suitable for 1S Li-ion or 2x AA battery systems.
When designing with this device, plan for decoupling 100 nF on VDD, place the ICSP/ICD pins (PGED/PGEC) on accessible test points for in-circuit programming, and configure the PPS (Peripheral Pin Select) carefully to avoid I/O conflicts.

Typical Applications
PIC16LF1824T-I/JQ is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, Wearable Health Monitoring Devices, Remote Controls and Consumer IR, HVAC and Building Automation Sensors, LED Lighting Controllers, Capacitive Touch User Interfaces.
Battery-Powered IoT Sensor Nodes
The PIC16LF1824T-I/JQ is ideally suited for battery-powered IoT sensor nodes due to its nanoWatt XLP technology with sub-1 uA sleep current and 1.8V-3.6V supply range. The 12-bit ADC with computation (ADC^2) autonomously averages sensor samples and only wakes the CPU when a threshold is exceeded, drastically reducing average power consumption. With 7 KB Flash, developers can implement Wireless M-Bus, LoRaWAN-node side filters, or BLE-beacon helpers. The 32 MHz internal oscillator avoids external crystals, shrinking the BOM and saving PCB area for thermistor, PIR, or environmental sensors in a 4x4 mm UQFN footprint.
Recommended
Wearable Health Monitoring Devices
For wearable fitness bands and health patches, the PIC16LF1824T-I/JQ provides the low-power compute needed for heart-rate, SpO2, and step-count algorithms. Its nanoWatt XLP sleep current of <1 uA preserves coin-cell battery life across weeks of continuous wear, while the 32 MHz performance handles on-device motion-fusion preprocessing. mTouch capacitive sensing enables touch buttons on the band without mechanical switches. The 14-pin UQFN package fits inside the small wristband form factor, and the 1.8V-3.6V range directly supports CR2032 coin cells without boost circuitry.
Recommended
Remote Controls and Consumer IR
Infrared remote controls benefit from the PIC16LF1824T-I/JQ's EUSART peripheral and DMA-driven PWM timers that emit NEC, RC5, or SIRC protocols with minimal CPU intervention. The 7 KB Flash holds a multi-protocol lookup table, while 256 B EEPROM stores pairing codes and learned button maps. nanoWatt XLP technology enables 2x AAA battery life of 1-2 years in standby. The 14-pin UQFN keeps the remote slim and the 32 MHz internal oscillator eliminates the external resonator typically required for IR carrier accuracy.
Recommended
HVAC and Building Automation Sensors
Building automation CO2, humidity, and occupancy sensors use the PIC16LF1824T-I/JQ as a low-power controller interfacing with I2C sensors and driving Modbus or BACnet links. The 12-bit ADC reads thermistor and photo-resistor signals for daylight harvesting, while the CWG (Complementary Waveform Generator) can drive HVAC damper actuators. The wide 1.8V-3.6V range lets the device run directly from a 24V HVAC bus with a simple LDO, and the 256 B EEPROM stores calibration constants across the 10-year equipment lifetime.
Recommended
LED Lighting Controllers
In decorative and architectural LED controllers, the PIC16LF1824T-I/JQ generates multiple PWM channels for RGB and tunable-white LED strings. The CWG peripheral can produce 16-bit resolution PWM at low frequencies for smooth dimming curves, while the DSM (Data Signal Modulator) handles dithering and flicker-free low-end dimming. The 32 MHz core runs color-mixing algorithms in software, and 7 KB Flash accommodates DMX512, DALI, or 0-10V protocol stacks. The 14-pin UQFN package fits into inline LED-driver housings.
Recommended
Capacitive Touch User Interfaces
The PIC16LF1824T-I/JQ integrates Microchip's mTouch hardware capacitive sensing module, supporting up to 12 touch buttons or a slider without external touch ICs. The CTMU (Charge Time Measurement Unit) provides robust capacitance-to-digital conversion immune to temperature drift, while the 12-bit ADC handles proximity wake-up. Designers can implement sealed touch keypads for appliances, white goods, and industrial controls. nanoWatt XLP technology lets the mTouch scan at <10 uA average, extending battery life in wireless keyfob and door-lock applications.

Key Differentiators
- Lowest-voltage XLP MCU in the PIC16F1824 family (vs PIC16F1824-I/JQ)
- Identical performance with industry-standard SOIC-14 footprint (vs PIC16LF1824-I/SL)
- More Flash and RAM than the PIC16LF1823 (vs PIC16LF1823T-I/JQ)
Design Notes
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin (pin 1) on the PIC16LF1824T-I/JQ. Add a 10 uF bulk capacitor at the regulator output. For nanoWatt XLP applications, route a separate analog supply trace to the AV-capable pins and use the VREGPM sleep regulator mode to drop current to <1 uA in Sleep. Estimated: at 3.3V supply and 32 MHz active, the part draws approximately 2.5 mA; at Sleep + WDT it drops below 1 uA.
The UQFN-14 (JQ) package has a center exposed thermal pad that MUST be soldered to a sufficient copper pour for mechanical strength and thermal dissipation, even though the part dissipates very little power. Route the ICSP signals (PGED/PGEC, equivalent to RC0/RC1) to accessible test points or a header for in-circuit programming and debug. Keep the trace between the internal oscillator and the VCAP pin short to minimise EMI.
Do not leave MCLR floating - tie it to VDD through a 10 kohm resistor or drive it actively. Verify the configuration word settings for the WDT, oscillator mode, and code protection before programming, since misconfiguration can lock out the device. The PPS (Peripheral Pin Select) registers must be unlocked with PPSLOCK before reassigning peripherals to avoid unexpected behaviour at startup.
When using the 32 MHz internal oscillator with the 4x PLL engaged, the system clock derives from the 8 MHz HFINTOSC. Place a 1 uF and a 100 nF ceramic pair on the VCAP pin to stabilise the PLL output. For I2C bus lines, add 4.7 kohm pull-up resistors to VDD; for longer buses above 500 pF total capacitance, consider 2.2 kohm. The EUSART baud-rate error budget at 32 MHz is typically below 1% when configured correctly.
