PIC16F18344T-I/GZ 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a rich set of peripheral blocks such as timers, ADCs, communication interfaces, and I/O ports. PIC16F MCUs use Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word and a modified Harvard architecture. They sit in the hierarchy of 8-bit microcontrollers -> microcontrollers -> microcontrollers and microprocessors -> semiconductor ICs, and are valued for predictable interrupt latency, deterministic execution, and ultra-low standby power.
Key features include Peripheral Pin Select (PPS), which allows remapping of digital peripherals to any I/O pin for board-layout flexibility, the Configurable Logic Cell (CLC) for glue-less hardware logic, Numerically Controlled Oscillator (NCO) and Complementary Waveform Generator (CWG) for precision signal generation, and a 10-bit ADC with Computation (ADC2) that automates averaging and threshold comparison. The XLP deep-sleep current is typically below 50 nA, making the part suitable for battery-powered designs where standby time dominates the energy budget.
Typical applications include ultra-low-power IoT sensor nodes, battery-powered wearables, LIN slave nodes in automotive body electronics, capacitive-touch user interfaces, and small general-purpose control boards. The 20-UQFN footprint is footprint-compatible with other PIC16F18xxx GZ-package variants, easing PCB reuse across a family of designs.
When designing with this part, ensure your programmer/debugger is set to a 4x4 UQFN-compatible header and allocate adequate copper area beneath the exposed pad for thermal dissipation and ground return. According to Microchip's device family documentation, the PPS registers must be initialized before first use of any remappable peripheral.

일반적인 애플리케이션
PIC16F18344T-I/GZ 적합 용도: 6 애플리케이션s: Ultra-Low-Power IoT Sensor Node, Battery-Powered Wearable Device, Automotive LIN Slave Node, Capacitive-Touch User Interface, Industrial Sensor Transmitter, Small General-Purpose Control Board.
Ultra-Low-Power IoT Sensor Node
PIC16F18344T-I/GZ fits IoT sensor nodes because its XLP deep-sleep current stays below 50 nA, allowing a coin-cell battery to last years between maintenance cycles. The 32 MHz CPU wakes from interrupt, reads a sensor via ADC2, transmits over a connected radio, and returns to sleep within microseconds, while the 256-byte EEPROM stores calibration and node identity across power cycles.
추천
Battery-Powered Wearable Device
PIC16F18344T-I/GZ suits wearables where PCB area is precious and standby current dominates battery life. The 4x4 mm UQFN-20 package occupies less than 16 mm squared of board area, while PPS lets you remap I2C, SPI, and UART to any pin, simplifying routing around a tiny display or biometric sensor. The CLC block can replace a discrete logic gate, shrinking the BOM further.
추천
Automotive LIN Slave Node
PIC16F18344T-I/GZ handles LIN slave duties in automotive body electronics (window lifts, seat controllers, mirror switches), where 8-bit determinism and low quiescent current are mandatory. The EUSART and Configurable Logic Cell can implement LIN protocol state machines in hardware, freeing the CPU for application tasks, while the 7 KB Flash accommodates a small LIN stack plus custom application code.
추천
Capacitive-Touch User Interface
PIC16F18344T-I/GZ drives capacitive-touch keypads and sliders through its mTouch peripheral and ADC2 with hardware averaging. The CWG can drive a piezo buzzer for haptic feedback without CPU intervention, and PPS lets the I2C touch controller share pins with an LED driver, simplifying PCB routing. The 20-UQFN footprint is small enough to fit behind a glass panel.
추천
Industrial Sensor Transmitter
PIC16F18344T-I/GZ serves in 4-20 mA loop-powered sensor transmitters because its XLP sleep current plus the 10-bit ADC2 let the MCU run entirely from the loop's 3.5 mA budget. The NCO generates a precise HART or custom modulation waveform without burdening the CPU, and the -40C to +85C industrial range handles most factory environments without derating.
추천
Small General-Purpose Control Board
PIC16F18344T-I/GZ anchors small 8-bit control boards such as fan controllers, LED drivers, and hobby robotics, where 32 MHz CPU, 7 KB Flash, and PPS give ample headroom for PWM, ADC, and serial tasks. The 20-UQFN footprint plus an exposed thermal pad simplifies PCB layout, and the MPLAB X IDE plus XC8 compiler keeps firmware development cost low.

설계 노트
Place a 100 nF decoupling capacitor within 3 mm of the VDD pin and a bulk 1 uF to 10 uF capacitor near the UQFN exposed pad. Use PPS to map the digital peripherals to high-impedance idle pins during sleep, so leakage does not dominate the deep-sleep budget. Estimated: at 50 nA sleep current and a 200 mAh CR2032, standby life approaches 450 years; practical life is constrained by battery self-discharge (~1 percent/year).
Solder the UQFN-20 (4x4) exposed thermal pad directly to a continuous ground copper pour on the top layer. Stencil openings on the thermal pad should be split into several smaller apertures (per IPC-7525) to avoid solder voids >25 percent. Keep-out the ground pour from the area beneath the ICSP header to simplify in-circuit programming.
Initialize Peripheral Pin Select (PPS) registers before first use of any remappable peripheral - peripherals default to a fixed pin at reset and will not function until PPS is configured. Also, configure the MCLR pin as a normal input via the CONFIG register when not using external reset, to avoid spurious resets from noise on the MCLR line.
규정 준수 정보
