PIC16F1824-I/SL 개요
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, optimized for low-cost, low-power embedded control. Within the broader product taxonomy, the PIC16F1824 belongs to the PIC10/12/16 mid-range family -> 8-bit PIC microcontroller -> microcontroller -> embedded processor -> semiconductor IC. XLP (eXtreme Low Power) is Microchip's umbrella of power-saving techniques (nanoWatt, deep sleep, ultra-low Iq peripherals) that target sleep currents measured in nanoamps rather than microamps.
Key features include 49-instruction enhanced mid-range core, 16-level hardware stack with overflow/underflow reset, 10-bit ADC with computation, mTouch capacitive-touch peripherals, multiple communication interfaces (I2C, SPI, EUSART), and 4 PWM modules with complementary outputs. The 32 MHz internal oscillator eliminates external crystals in many designs, while the wide 1.8-5.5V operating range allows direct connection to 2-cell alkaline, single-cell Li-ion, or 3.3V regulated rails.
The PIC16F1824 uses a Harvard RISC architecture with 14-bit wide instruction words, automatic interrupt context saving, and configurable peripheral pin select via the APFCON0/APFCON1 registers. Integrated CIPs (Core Independent Peripherals) such as the CWG, NCO, and PWM modules allow real-time control tasks to run without CPU intervention, freeing the core for application logic.
Typical applications include consumer appliances, IoT sensor nodes, battery-powered handheld instruments, LED lighting controllers, and capacitive-touch human-machine interfaces (HMI). Designers select this MCU when energy budget, pin count, and cost matter more than raw processing throughput.
When designing with this part, choose decoupling per Microchip guidelines: a 0.1 uF ceramic on VDD plus bulk capacitance near high-current loads. Place the ICSP/ICD pins on accessible test points to support in-circuit programming and debugging with PICkit 3 or MPLAB ICD 3.

일반적인 애플리케이션
PIC16F1824-I/SL 적합 용도: 6 애플리케이션s: Battery-Powered IoT Sensor Nodes, Capacitive Touch HMI Panels, LED Lighting Control and Drivers, Consumer Appliance Control Boards, Automotive Interior Accessories, Industrial Sensor Transmitters.
Battery-Powered IoT Sensor Nodes
The PIC16F1824-I/SL is ideal for battery-powered wireless sensor nodes thanks to its nanoWatt XLP technology, which achieves sleep currents below 50 nA with full RAM retention and RTCC running. Its 32 MHz internal oscillator eliminates external crystal current draw, while the 1.8V-5.5V range works directly from 2-cell alkaline or single-cell Li-ion batteries. The integrated 8-channel 10-bit ADC with computation, plus EUSART for radio modules like Sub-GHz transceivers, make it a fit for periodic-sensing applications where the MCU wakes briefly, samples a sensor, transmits, and returns to deep sleep. Ten-year battery life targets in coin-cell powered designs are realistic with proper duty-cycling.

Capacitive Touch HMI Panels
The PIC16F1824-I/SL integrates Microchip's mTouch capacitive-touch sensing peripherals (CPS modules) directly on-chip, enabling button, slider, and wheel interfaces without external touch ICs. With up to 8 capacitive touch channels multiplexed through the analog pin mux and hardware noise-filtering, it can replace mechanical buttons in appliance front panels, lighting controls, and consumer electronics. The 4 PWM modules drive LED feedback or haptic actuators, while the integrated ADC handles proximity sensing. Designers benefit from a single-chip HMI solution that reduces BOM cost and PCB footprint compared to discrete touch controllers.
추천
LED Lighting Control and Drivers
The PIC16F1824-I/SL's 4 PWM modules with complementary outputs and configurable dead-band make it well-suited for LED driver control, including dimming via PWM duty cycle and color-mixing in RGB or RGBA fixtures. The high-speed 32 MHz CPU executes lighting algorithms (CCT adjustment, fade effects, scene memory) in real time. Integrated I2C and EUSART support DMX512 or DALI lighting protocol bridging, while the wide 1.8-5.5V supply range allows direct connection to 5V or 3.3V LED-driver rails. The hardware CWG (Complementary Waveform Generator) simplifies half-bridge and full-bridge LED driver designs.
추천
Consumer Appliance Control Boards
The PIC16F1824-I/SL is widely deployed in white-goods and small-appliance control boards (coffee makers, blenders, washing machine user interfaces) where cost-effectiveness and reliability outweigh raw performance. Its 7 KB Flash holds appliance control firmware including state machines, sensor calibration, and fault detection, while 256-byte EEPROM stores user preferences and run-hour counters. The integrated EUSART interfaces with inverter modules, and the 10-bit ADC reads temperature sensors and motor currents. Industrial -40 to +85 C temperature rating covers typical kitchen and laundry environments.
추천
Automotive Interior Accessories
While the standard PIC16F1824-I/SL is industrial-grade, the AEC-Q100 equivalent PIC16F1824-E/SL (extended temperature) is deployed in non-safety automotive interior applications such as ambient lighting, seat-position memory, and HVAC blend-door actuators. The wide -40 to +125 C operating range handles cabin-temperature extremes, and the 32 MHz internal oscillator eliminates crystal-induced failures. The 4 PWM outputs drive servo motors or LEDs, and the EUSART interfaces with body control modules over LIN or CAN transceivers. Designers migrating to AEC-Q100 must verify pin-compatible parts in the Microchip automotive portfolio.
추천
Industrial Sensor Transmitters
The PIC16F1824-I/SL serves as the core of 4-20 mA loop-powered or 0-10V industrial sensor transmitters, digitizing signals from pressure, temperature, or flow sensors via its 10-bit ADC and transmitting over analog current loops or RS-485. The 32 MHz CPU executes linearization and calibration algorithms, while 256-byte EEPROM holds calibration coefficients. The integrated I2C supports digital sensor front-ends, and the SPI bus drives digital displays. Wide 1.8-5.5V supply and -40 to +85 C industrial range cover factory-floor and process-control environments. The nanoWatt XLP technology enables 4-20 mA loop-powered designs where total current budget is 3.5 mA.

설계 노트
For battery-powered designs, leverage the nanoWatt XLP sleep modes: Dsleep (deep sleep with RTCC) achieves 50 nA typical with full RAM retention per Microchip datasheet DS41419A. Place a 100 nF ceramic decoupling capacitor on VDD (pin 14) as close as physically possible to the IC, with bulk capacitance (1-10 uF) sharing the same ground via a star topology. Use low-Iq voltage regulators (Microchip MCP1700 or similar) for the supply rail to preserve sleep current budgets. Avoid floating I/O pins - configure unused pins as outputs low to prevent shoot-through current in sleep mode.
Allocate test points on the ICSPDAT (pin 1) and ICSPCLK (pin 2) signals for in-circuit programming and debugging with PICkit 3 or MPLAB ICD 3 - a 0.1-inch header or pogo-pad land pattern is recommended. The MCLR/VPP pin (pin 4) requires a 10 kohm pull-up to VDD and a 100 nF cap to ground for proper reset operation per Microchip guidelines. Keep crystal traces (if used) short and shield with a ground pour; the internal 32 MHz oscillator eliminates this requirement for most designs.
Do not exceed 5.5V on VDD - the absolute maximum rating is 6.5V and operation above 5.5V voids specifications. Configure the Configuration Words (CONFIG1/CONFIG2) before any code execution; failure to do so leaves the device in factory-default state with potentially unsafe clock and watchdog settings. The LF variant (PIC16LF1824) must NOT be operated above 3.6V even though it shares the same pinout - verify the suffix on the package marking. When migrating firmware between PIC16F1824 and PIC16F1823, account for 4 KB vs 7 KB Flash size limits - code compiled for 1824 may overflow on 1823.
