PIC16LF1823T-I/JQ 개요
An 8-bit PIC microcontroller is a Harvard-architecture RISC device that executes one instruction per clock cycle from on-chip Flash, with peripherals (ADC, PWM, comparators, EUSART, I2C/SPI) tightly integrated for embedded control. Within the broader taxonomy, it sits as: MCU -> 8-bit microcontroller -> PIC microcontroller -> Microchip mid-range family -> embedded semiconductor. The PIC16LF1823 belongs to the PIC16 enhanced mid-range core, which adds C compiler-friendly orthogonal instructions, hardware multiplier assist, and ultra-low-power sleep modes.
Key features include 3.5KB self-programmable Flash, 256 bytes of EEPROM, 128 bytes of RAM, a 10-bit ADC with up to 8 channels, enhanced PWM, mTouch capacitive sensing support, two comparators, and a fixed 1.024V internal reference. It also supports peripheral pin select, enabling flexible PCB routing. The UQFN EP package measures just 4 x 4 mm with an exposed thermal pad for improved dissipation in space-constrained layouts.
Architecturally, the PIC16LF1823 combines a wide operating voltage range with low-power modes (down to sub-microamp sleep) and a fast 32 MHz oscillator, allowing engineers to balance throughput and energy budget at runtime. The integrated nanoWatt XLP technology makes it suitable for designs that spend long intervals in standby.
Typical applications include battery-powered sensor nodes, wearable fitness and medical accessories, IoT endpoints, consumer remote controls, and low-power human-interface devices. It is also used in automotive body and lighting subsystems where extended temperature and AEC-Q100 grades are required from sibling parts.
Designers should note that JTAG-style debug requires ICSP/ICD via PGC/PGD pins, and the UQFN EP land pattern must include a properly soldered thermal pad to avoid mechanical stress. External decoupling of 100 nF near VDD is recommended.

일반적인 애플리케이션
PIC16LF1823T-I/JQ 적합 용도: 6 애플리케이션s: Battery-Powered IoT Sensor Nodes, Wearable Fitness & Medical Devices, Consumer Remote Controls & HMI, Industrial Sensor Conditioning Modules, Automotive Body & Lighting Controllers, Low-Power Standby / Always-On Controllers.
Battery-Powered IoT Sensor Nodes
The PIC16LF1823T-I/JQ is well-suited for coin-cell or Li-ion powered wireless sensor endpoints where standby current dominates battery life. Its 1.8V-3.6V operating range matches 2xAA alkaline (~3V) and CR2032 (3V) chemistries directly without a boost converter, eliminating quiescent losses from extra stages. The nanoWatt XLP technology delivers sub-microamp sleep currents, and the integrated 10-bit ADC plus two comparators let it condition sensor signals and wake the MCU on threshold crossings, keeping radio duty cycles short and energy budgets in the months-to-years range.
추천
Wearable Fitness & Medical Devices
Wearable health bands and continuous-monitoring medical accessories benefit from the PIC16LF1823T-I/JQ's UQFN EP-16 footprint measuring only 4x4 mm, which fits inside a wristband or chest strap without dominating board area. The 12 digital I/O pins with peripheral pin select allow flexible routing for display, button, and sensor leads around curved PCB outlines. The integrated 10-bit ADC supports heart-rate, SpO2, and temperature sensor front-ends, while nanoWatt XLP sleep modes extend wear time on coin-cell batteries by allowing the MCU to wake only on timer or external interrupts.
추천
Consumer Remote Controls & HMI
Infrared remote controls, BLE-to-IR bridges, and small human-interface devices fit the PIC16LF1823T-I/JQ perfectly: the ECCP PWM module can drive IR LEDs at 38 kHz carrier, the mTouch peripheral supports capacitive buttons and sliders without external touch ICs, and the UQFN EP-16 package keeps BOM low in high-volume consumer SKUs. The EUSART and MSSP provide UART and I2C/SPI for add-on radios. Low sleep current at 1.8V operation lets the device sit for years on a pair of AAA batteries.
추천
Industrial Sensor Conditioning Modules
Industrial 4-20mA loop-powered transmitters, RTD/thermocouple signal conditioning, and 24V-rail digital I/O modules rely on the PIC16LF1823T-I/JQ for its 10-bit ADC with up to 8 channels, two on-chip comparators for limit detection, and the wide -40C to +85C industrial temperature range. The MSSP (I2C/SPI) interfaces directly to digital sensor front-ends, while the EUSART handles RS-485 transceivers via external half-duplex drivers. Operation from 1.8V-3.6V requires a small LDO from typical 24V or 12V industrial rails.
추천
Automotive Body & Lighting Controllers
Interior lighting, mirror controllers, and small body-electronics modules in entry-level vehicles often adopt the PIC16LF1823 family thanks to its comprehensive peripheral set, automotive-grade part numbers in the same die family, and the UQFN EP-16 footprint that meets tight connector-board layouts. The ECCP module handles LED dimming with hardware PWM, while the ADC reads ambient light sensors and the EUSART interfaces to LIN slaves via external LIN transceivers. Use the AEC-Q100 qualified PIC16F1823T-I/JQ sibling for production automotive units.
추천
Low-Power Standby / Always-On Controllers
Smart-home hubs, set-top boxes, and computer peripherals need a small 'always-on' companion microcontroller for watchdog, button scan, and system telemetry while the main processor is asleep. The PIC16LF1823T-I/JQ's sub-microamp sleep current draws nearly no power from the system 3.3V rail, while its interrupt-on-change pins can wake the main processor on user input. Its small UQFN EP-16 package fits next to a coin-cell holder or backup supercapacitor, and its MSSP/EUSART let it communicate with the host SoC at low duty cycles.

설계 노트
The PIC16LF1823T-I/JQ is a 3.3V-class MCU and must be supplied from a regulated rail within 1.8V-3.6V. VDD noise must be less than 100 mVpp - use a 10 uF bulk and 100 nF decoupling capacitor placed within 5 mm of the VDD pin. The exposed thermal pad (EP) must be soldered to the PCB and connected to VSS to provide the lowest-inductance ground return and a stable thermal path; without a soldered EP the device may overheat at higher clock rates and will not meet ESD specifications.
Route ICSP signals (PGC/PGD) away from switched power traces and noisy I/O. Place a 4.7 kohm pull-up on MCLR for normal operation and ensure the ICSP connector footprint can tolerate the programming header. For UQFN packages, the recommended PCB land pattern uses NSMD pads with 1:1 ratio to lead pitch; under- or over-sized pads cause solder joint defects during reflow. Always follow IPC-7351 guidelines for UQFN land pattern design and request a DFM review from your assembly house before volume production.
Do not assume the 32 MHz internal oscillator drifts less than 1% over voltage and temperature - verify critical baud rates with the EUSART's auto-baud feature when possible. The ADC input impedance degrades at high source impedance; keep source impedance below 1 kohm or use the on-chip ADC acquisition timer (ACQT) to charge the holding capacitor adequately. Watch the MCLR pin during in-circuit programming - inadvertently driving it low during normal operation forces a reset, and floating MCLR can cause spurious resets in noisy environments.
