PIC16F15344-E/SO Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data memory, and peripherals such as timers, ADC, communication interfaces, and I/O. The 8-bit PIC MCU family sits in the broader hierarchy of embedded microcontrollers -> microcontrollers -> integrated circuits -> semiconductors, serving cost-sensitive and power-constrained designs where 32-bit processing is unnecessary.
Key features include 7 KB Flash, 512 B SRAM, 4 PWMs, a comparator, a 5-bit DAC, an ADC, 4 Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), 2 EUSART, and SPI/I2C communication. Core Independent Peripherals (CIPs) operate without CPU intervention, allowing deterministic real-time response and reducing firmware complexity.
The PIC16F15344-E/SO operates from 2.3V to 5.5V (industrial temperature range -40C to +125C) and uses Microchip's XLP architecture with nanoWatt XLP sleep currents. The 20-pin SOIC package supports through-hole-friendly hand-soldering and reflow profiles compatible with JEDEC J-STD-020.
Typical applications include low-power IoT sensor nodes, battery-powered consumer devices, LED lighting controllers, simple motor control, and home appliances. The combination of EUSART, SPI, and I2C plus PWM and CWG suits brushed DC and small BLDC fan control.
When designing with this device, ensure decoupling capacitors (100 nF plus 10 uF bulk) are placed within 5 mm of VDD, leave the ICSPCLK/ICSPDAT pins accessible for in-circuit programming, and use Microchip's MPLAB X IDE with the XC8 compiler for code development.

Typische Anwendungen
PIC16F15344-E/SO ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Node, LED Lighting Controller, Brushed DC Motor and Fan Control, Home Appliance User Interface, Industrial Sensor Transmitter, Consumer Remote Control and HMI.
Battery-Powered IoT Sensor Node
The PIC16F15344-E/SO is well-suited for battery-powered IoT sensor nodes thanks to its XLP nanoWatt sleep architecture, 2.3-5.5V supply range, and Core Independent Peripherals that wake the MCU only on real events. The 10-bit ADC reads temperature, humidity, or analog sensor outputs while CLCs combine comparator outputs for threshold detection without firmware overhead. EUSART or I2C handles wireless module (LoRa, BLE, sub-GHz) interfacing. With 7 KB Flash, common IoT stacks (Modbus, simple TLS, sensor calibration) fit comfortably. The 512 B SRAM buffers sensor bursts before transmission. At sleep currents typically <1 uA, a 2xAA alkaline battery can power multi-year deployments.
Empfohlen
LED Lighting Controller
The PIC16F15344-E/SO drives LED lighting applications via its 4 PWM channels and Complementary Waveform Generator (CWG) for high-current half-bridge FET drive. The 5-bit DAC sets LED current references while 10-bit ADC reads photodiode feedback for closed-loop brightness or color-mixing control. EUSART or I2C interfaces to wireless modules (BLE Mesh, Zigbee, LoRa) for smart-bulb designs. With 32 MHz CPU and CIP-driven PWM, dimming curves and color transitions run on hardware with minimal CPU load. The 2.3-5.5V supply simplifies driver design with either 3.3V or 5V LED rails.
Empfohlen
Brushed DC Motor and Fan Control
The PIC16F15344-E/SO controls small brushed DC motors and fans using its 4 PWMs, CWG, and built-in comparator for back-EMF sensing or current-limit feedback. The 5-bit DAC programs current-limit thresholds without external DAC chips, and CLCs combine tachometer inputs with PWM duty for closed-loop RPM control. At 32 MHz, the MCU implements PI control loops in firmware with sample periods under 100 us. Operating temperature range up to +125C supports under-hood automotive fan control or industrial exhaust fans. EUSART enables LIN bus or RS-485 command interface for networked fan trays.
Empfohlen
Home Appliance User Interface
The PIC16F15344-E/SO serves as the user-interface controller in home appliances such as washing machines, dishwashers, ovens, and coffee makers. The MCU drives 7-segment or LCD displays, scans capacitive touch buttons via the comparator, and communicates with the main appliance MCU through I2C or UART. With 7 KB Flash, the device stores multiple menu languages, error logs, and diagnostic routines. The CWG generates buzzer tones for end-of-cycle alerts. Industrial -40C to +125C temperature range tolerates kitchen or garage environments with thermal cycling.
Empfohlen
Industrial Sensor Transmitter
The PIC16F15344-E/SO forms the core of 4-20 mA loop-powered or RS-485 industrial sensor transmitters. The 10-bit ADC digitizes sensor inputs (pressure, flow, level), the EUSART outputs RS-485 Modbus RTU frames, and the PWM drives a 4-20 mA current loop via an external op-amp. With XLP sleep modes, average current consumption stays below 3.5 mA to support loop-powered operation. The industrial temperature range (-40C to +125C) and 20-pin SOIC package fit standard industrial enclosures. 7 KB Flash holds Modbus register maps, calibration tables, and linearization routines.
Empfohlen
Consumer Remote Control and HMI
The PIC16F15344-E/SO powers consumer remote controls, thermostats, and small human-machine interfaces (HMI). The MCU scans keypads, drives OLED or character LCDs via SPI/I2C, and communicates over IR (via PWM) or sub-GHz RF (via EUSART). Sleep currents under 1 uA extend battery life in remote controls for years on a single coin cell. The 7 KB Flash supports multiple IR protocols (NEC, RC5, SIRC) or RF protocol stacks. The 20-pin SOIC keeps the design compact and low-cost for consumer pricing.

Designhinweise
Place a 100 nF ceramic decoupling capacitor within 5 mm of the VDD pin (pin 11) and a 10 uF bulk capacitor at the board supply entry point. For battery-powered designs, the XLP sleep current can drop below 1 uA only when all unused peripherals are disabled in firmware and the MCLR pin is tied to VDD through a 10 kohm resistor (no high-current pull-ups).
Keep the ICSP programming footprint (RA0/ICSPCLK, RA1/ICSPDAT, MCLR/VPP) accessible on the PCB even in production designs. This allows firmware updates and factory calibration without rework. The 20-pin SOIC land pattern uses standard JEDEC SO-20 dimensions with 1.27 mm pin pitch and 7.50 mm body width.
The MCLR pin (pin 1) must not be left floating; either tie to VDD through a 10 kohm resistor or use the internal MCLR configuration. Floating MCLR causes random resets. The ADC reference voltage (VREF+/VREF-) must be configured correctly before ADC conversion, or readings will use VDD as default reference with reduced accuracy.
