PIC16LF15344-E/SO Übersicht
What is an 8-bit microcontroller? An 8-bit microcontroller (MCU) is a small computer on a single integrated circuit containing an 8-bit CPU core, Flash program memory, SRAM data memory, and a rich set of on-chip peripherals. PIC microcontrollers sit within the broader hierarchy: PIC microcontroller -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. The 'LF' prefix indicates the low-voltage 'F' (Flash) process node, allowing operation down to 1.8V and enabling battery-friendly XLP operation.
Key features of the PIC16LF15344 include four 10-bit PWMs with complementary waveform generation, a hardware 5-bit/8-bit DAC, an analog comparator, a 10-bit ADC with computation, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), two EUSART modules, and SPI/I2C interfaces. The XLP variant offers nanoWatt XLP sleep currents typically below 50 nA in Sleep with peripherals off.
Architecturally the device is built on an enhanced mid-range 8-bit core supporting 49 instructions and a 16-level hardware stack, with a 32 MHz internal oscillator that eliminates the need for an external crystal in most designs. Core Independent Peripherals (CIPs) such as the CLC, CWG, and NCO allow hardware-driven state machines without CPU intervention, reducing power and code footprint.
Typical applications include battery-powered IoT sensor nodes, low-power wireless remotes, white goods and HMI controls, LED lighting controllers, automotive body and accessory electronics, and consumer devices requiring small pin-count XLP solutions. Designers choose it when code size, peripheral count, and ultra-low sleep current must coexist in a 20-pin footprint.
When designing with this MCU, follow the Microchip MPLAB X IDE toolchain and configure the configuration bits carefully for the chosen oscillator and watchdog. Decouple VDD with a 100 nF capacitor close to the pin, and route MCLR through the recommended 10 kohm pull-up if external reset is required.

Typische Anwendungen
PIC16LF15344-E/SO ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Node, Wireless Remote Control (HID / Consumer), White Goods and HMI Control, LED Lighting Controller, Automotive Body and Accessory Module, Industrial Sensor and Process Transmitter.
Battery-Powered IoT Sensor Node
The PIC16LF15344-E/SO is well suited for battery-powered IoT sensor nodes that spend most of their time in sleep and wake briefly to transmit. With XLP technology delivering nanoWatt sleep currents (typically below 50 nA) and a wide 1.8 V to 3.6 V operating range, this MCU can run directly from a single CR2032 coin cell or two AAA cells for months or years. The 10-bit ADC with computation performs on-chip sensor averaging without waking the CPU, while the four CLCs implement hardware state machines for wake-on-event signaling. The two EUSARTs enable simultaneous sensor-bus and radio-module communication, reducing external component count and bill of materials in compact IoT designs.
Empfohlen
Wireless Remote Control (HID / Consumer)
The PIC16LF15344-E/SO is an excellent fit for low-power wireless remote controls such as TV remotes, key fobs, and presentation clickers. Its 32 MHz core runs the application code and a transmit routine for sub-GHz or IR LED drivers in microseconds, then drops back to sleep for months on a coin cell. The Complementary Waveform Generator (CWG) directly drives half-bridge or full-bridge MOSFETs for IR or piezo loads, offloading timing-critical waveform generation from the CPU. Two EUSARTs allow debug logging and main-link communication simultaneously, while the 18 I/O pins handle button matrix scanning and LED feedback without external glue logic.
Empfohlen
White Goods and HMI Control
The PIC16LF15344-E/SO drives user interface panels on white goods such as washing machines, dishwashers, and ovens. The 32 MHz core handles capacitive-touch scanning, LED dimming, and seven-segment display refresh via the four PWM channels and four CLCs. The CWG generates complementary PWM outputs for synchronous motor or Triac drive signals, eliminating firmware timing jitter. Industrial-grade -40C to +125C operation ensures reliability inside hot appliance enclosures. XLP sleep modes let the MCU sit idle between user interactions with negligible battery drain for clock backup or end-of-cycle memory retention.
Empfohlen
LED Lighting Controller
The PIC16LF15344-E/SO controls constant-current LED drivers in architectural lighting, RGB strips, and horticultural fixtures. Its four 10-bit PWM channels with complementary outputs provide smooth dimming without flicker, while the CWG generates high-frequency switching waveforms for synchronous buck or boost LED driver topologies. The 1.8 V to 3.6 V supply range simplifies designs powered by 3.3 V rails or single-cell Li-ion battery packs, while XLP technology keeps standby current below 50 nA when the lighting is off. The hardware DAC produces reference voltages for closed-loop current control, and the 10-bit ADC reads photodiode or thermistor feedback for daylight harvesting and thermal protection.
Empfohlen
Automotive Body and Accessory Module
The PIC16LF15344-E/SO operates in non-safety automotive body electronics such as interior lighting controllers, seat heaters, and accessory power modules. The extended -40C to +125C temperature range and eXtreme Low-Power XLP technology support always-on modules that draw microamps during key-off. The CWG module generates complementary gate-drive signals for half-bridge drivers controlling seat heater elements or fan motors. Dual EUSARTs allow simultaneous LIN-bus communication and diagnostics over UART. Designers should note that the E temperature grade suffix is industrial-grade; automotive-grade AEC-Q100 qualified variants may be selected from the same PIC16LF15344 family for safety-relevant systems.
Empfohlen
Industrial Sensor and Process Transmitter
The PIC16LF15344-E/SO acts as the local controller in 4-20 mA loop-powered or battery-backed industrial sensor transmitters. The 10-bit ADC with computation oversamples sensor signals for noise reduction, while the 5-bit/8-bit DAC generates the 4-20 mA loop current under closed-loop software control. XLP operation below 1 mA active current suits energy-harvesting or loop-powered transmitters with strict power budgets. Two EUSARTs and SPI/I2C enable simultaneous HART-modem communication and digital sensor interfacing. The industrial -40C to +125C temperature grade ensures operation in factory automation cabinets and outdoor instrumentation.

Wichtigste Unterscheidungsmerkmale
- Highest CLC count in the PIC16(L)F153xx SOIC-20 family (vs. PIC16LF15324-E/SO)
- Dual EUSART versus single EUSART in the 15324 variant (vs. PIC16LF15324-E/SO)
- Low-voltage XLP support down to 1.8 V (vs. PIC16F15344-E/SO)
Designhinweise
The PIC16LF15344-E/SO requires a single 100 nF ceramic decoupling capacitor placed within 3 mm of the VDD pin (pin 19) and VSS pin (pin 18). According to the Microchip datasheet, VDDIO (pin 20) should be tied to VDD through its own short trace; tie VSS pins together at the package. For low-noise analog performance, add a 10 uF bulk capacitor near the MCU and a small ferrite bead on the analog supply if the design shares the rail with switching converters.
When migrating between the PIC16LF15344 (1.8 V to 3.6 V) and the PIC16F15344 (2.3 V to 5.5 V), verify that all I/O peripherals and sensors tolerate the lower VDD on the LF variant. Some 5 V sensors will not register logic-high at 1.8 V. The configuration bits for oscillator selection, watchdog timer, and code protection must be set in the IDE; an incorrect WDTE setting can cause unintended resets in field-deployed units.
Place the MCU so that the SOIC package's exposed copper pour is connected to a quiet ground plane. According to the Microchip datasheet, the 20-pin SOIC is a single-row package with no thermal pad; ensure wide VDD and VSS traces (at least 0.4 mm) and keep high-speed switching traces away from the analog pins RA0-RA2 to avoid ADC crosstalk. Decoupling capacitors should use short, direct vias to the ground plane.
Compliance-Informationen
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified - this is the industrial-grade E suffix variant. AEC-Q100 versions exist in the same PIC16LF15344 family for automotive applications.
