PIC16F1824-E/JQ 概要
An 8-bit microcontroller (MCU) is a small single-chip computer built around an 8-bit data path, widely used as the lowest layer of embedded intelligence in products ranging from consumer white goods to industrial sensor nodes. Within the broader semiconductor taxonomy, the PIC16F1824 belongs to the 8-bit microcontroller class, then to the enhanced mid-range PIC16 family, then to Microchip's XLP™ ultra-low-power sub-line, and finally to the mTouch™ capacitive-sensing-capable series. It typically operates as the central control element in an embedded system hierarchy: sensor/peripheral → PIC16F1824 → communication transceiver → host MCU or wireless SoC.
Key features include eXtreme Low Power (XLP) technology with sub-µA sleep currents, an active mode current of approximately 1.8 mA at 32 MHz / 3.3 V, integrated mTouch™ capacitive-touch sensing support, and a wide operating voltage range from 1.8 V to 5.5 V. The device supports in-circuit serial programming (ICSP) and in-circuit debug (ICD) via PICkit™ 3 or MPLAB® ICD 3, eliminating the need for an external debug header. Extended temperature range is -40 °C to +125 °C (E suffix), and the -JQ package denotes 16-UQFN with EP in tube packaging.
Typical applications include capacitive touch user interfaces for small appliances and IoT sensor nodes, low-power battery-powered remote controls and wearables, LED lighting controllers, automotive body and sensor subsystems where AEC-Q100 grade parts are acceptable, and general-purpose logic replacement. The CWG and CLC peripherals make it especially attractive for driving power MOSFETs in motor control and switched-mode power supply housekeeping blocks.
When designing with this part, allocate a 0.1 µF decoupling capacitor as close as possible to VDD, and follow Microchip's UQFN-EP PCB layout guidelines (thermal pad must be soldered to the ground plane for thermal and electrical performance). For capacitive touch applications, keep the sense trace short and guarded by a ground ring to minimise noise pickup. The internal 32 MHz oscillator eliminates an external crystal in most designs, saving two GPIOs and PCB area.

主な用途
PIC16F1824-E/JQ の用途: 6 件s: Capacitive Touch User Interface, Low-Power IoT Sensor Node, LED Lighting Controller, Automotive Body Electronics, Small Motor Control (Fan / Pump), Industrial Sensor Conditioning.
Capacitive Touch User Interface
The PIC16F1824-E/JQ is purpose-built for capacitive touch user interfaces thanks to its on-chip mTouch™ peripheral and CVD (Capacitive Voltage Divider) hardware. The 12 available I/O pins can each be assigned as a touch channel, supporting up to 12 buttons or a smaller number of sliders/wheels. With XLP™ technology, sleep current drops below 1 µA between scans, making it ideal for mains-powered or battery-powered appliances. Its 32 MHz CPU executes the touch-scan and post-processing in microseconds, leaving ample bandwidth for system housekeeping.
おすすめ
Low-Power IoT Sensor Node
For battery-powered IoT sensor nodes the PIC16F1824-E/JQ offers sub-µA sleep current, integrated 10-bit ADC for analog sensor interfaces, and EUSART/SPI/I2C for connecting radios or sensors. Its 1.8 V minimum supply lets it run directly from a single lithium cell or two alkaline AAs. With 7 KB Flash the device accommodates BLE/Zigbee stack helper code or LoRaWAN driver firmware on the MCU side, paired with an external radio module. The CWG peripheral can drive low-side MOSFETs for switching external loads during wake events.
おすすめ
LED Lighting Controller
The PIC16F1824-E/JQ drives single- or multi-channel LED strings using its enhanced PWM modules and Complementary Waveform Generator (CWG). The CWG simplifies synchronous buck or boost LED driver topologies by generating complementary gate-drive waveforms with programmable dead time, while the 10-bit ADC closes the loop by sensing LED current via a shunt resistor. Its wide 1.8 V to 5.5 V operating range accommodates both 3.3 V logic and 5 V analog drive needs in the same design.
おすすめ
Automotive Body Electronics
Automotive body-electronics modules — including HVAC flap control, mirror positioning, and seat-actuator drivers — benefit from the PIC16F1824-E/JQ's extended -40 °C to +125 °C temperature grade, 32 MHz computational headroom, and integrated CIP peripherals. The EUSART auto-baud feature supports LIN-bus slave communication when paired with an external LIN transceiver, while the CWG peripheral generates the gate-drive waveforms needed for small brushed DC motor PWM. AEC-Q100 qualified variants exist in the same family for designs that require full automotive certification.
おすすめ
Small Motor Control (Fan / Pump)
The PIC16F1824-E/JQ's Complementary Waveform Generator, multiple PWM channels, and 32 MHz core make it a compact solution for small brushed DC or single-phase BLDC motor control in fans, pumps, and small appliances. The CLC peripheral combines analog comparator outputs with timer events to create hardware fault-detection, offloading the CPU from critical timing-sensitive tasks. The 10-bit ADC closes current and back-EMF loops, while the 12 I/O pins are sufficient for Hall-sensor input, MOSFET gate drive, and tachometer feedback.
おすすめ
Industrial Sensor Conditioning
For 4-20 mA loop-powered industrial sensors, the PIC16F1824-E/JQ integrates a 10-bit ADC (good for 0.1 %-class readings when oversampled) plus on-chip voltage reference. Its 1.8 V minimum operating voltage suits loop-powered designs that derive MCU supply from the 4-20 mA current. The EUSART auto-baud feature supports HART modem handshake when an external HART modem IC is added. Industrial -40 °C to +85 °C or extended -40 °C to +125 °C operation is available via the -I or -E temperature suffixes respectively.

設計ノート
Place a 0.1 µF ceramic decoupling capacitor as close as physically possible to the VDD pin (pin 1) and a bulk 1-10 µF tantalum or ceramic capacitor on the same supply rail within 5 mm. The PIC16F1824's internal voltage regulator (when present on -LF variants) requires both high-frequency and bulk decoupling to prevent digital hash from coupling into analog readings. For battery-powered designs, use the VREGPM sleep-mode feature to drop the internal regulator quiescent current during extended sleep periods.
The 16-UQFN exposed thermal pad (pin 14 / EP) must be soldered to a continuous ground copper pour to meet the datasheet's thermal resistance (θJA) specification. Without proper thermal pad soldering, junction temperature can exceed rated limits at elevated ambient temperatures above 85 °C. Aim for at least 100 mm² of 1 oz copper on the top layer, stitched to the bottom layer with 0.3 mm thermal vias on a 1 mm pitch. This is especially critical for -E (125 °C) variants in enclosed automotive housings.
When designing capacitive touch sensors on the PIC16F1824, keep the sense trace as short as possible (target < 50 mm) and guard it with a ground ring on the same layer. Avoid routing touch traces parallel to noisy digital lines; if crossing is unavoidable, route them perpendicular. Use the CVD peripheral instead of legacy CTMU when possible — CVD provides superior noise immunity in the presence of switching power converters and high-current LED PWM traces.
Do not forget to configure the APFCON0/APFCON1 registers if you remap peripheral functions to alternative pins — pin numbers in the UQFN-16 (JQ) package are fewer than in the QFN-20 (ML) package, and some peripherals (PWM, I2C, SPI) have fixed alternate pin locations that may not match every design's PCB layout. Also remember to disable the JTAG port on POR (default off) and clear the WDT postscaler in software at startup if you want maximum CPU performance.
