PIC16LF15344T-I/SS Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), and a rich set of peripherals such as timers, ADCs, communication interfaces, and GPIO onto one IC. MCUs sit at the top of the embedded computing hierarchy - above microprocessors (which require external memory) and below SoCs that add application processors and high-speed interfaces. The 8-bit class occupies the low-power, cost-sensitive end of this hierarchy, where deterministic behavior and low sleep current matter more than raw compute.
Key features of the PIC16LF15344T-I/SS include 4 PWM channels, a hardware comparator, a 5-bit and 10-bit DAC, a 10-bit ADC, 4 Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), 2 EUSART, SPI, and I2C peripherals. The XLP technology enables sleep currents in the nanoampere range, making the device suitable for battery-powered and energy-harvesting designs. The integrated Core Independent Peripherals (CIPs) execute functions without CPU intervention, further reducing active power consumption.
Technically, the device uses a RISC-based PIC16 core with a single-cycle instruction architecture except for program branches, supported by a hardware Multiply/Divide and a 32 kHz to 32 MHz internal oscillator. The integrated CIP block (CLC, CWG, NCO, PWM) allows autonomous peripheral interaction and event-driven behavior. The device is rated for -40C to +85C industrial operation and supports in-circuit debugging via ICD.
Typical applications include IoT sensor nodes, wearable health monitors, low-power wireless remote controls, battery-powered instrumentation, home automation end nodes, and small motor control. The combination of multiple PWMs and CWG makes it well suited for LED lighting and small BLDC driver control loops.
When designing with this part, ensure decoupling capacitors (typically 100 nF) are placed within a few millimeters of VDD/VSS, and verify the unused I/O pins are configured as outputs to minimize current leakage. The SSOP-20 footprint also enables easy migration to the PIC16F15344 variants operating up to 5.5 V.

Typical Applications
PIC16LF15344T-I/SS is suitable for 6 applications: IoT Sensor Node, Battery-Powered Wearable Health Monitor, Wireless Remote Control (Sub-GHz/IR), Industrial Process Sensor / 4-20 mA Loop Transmitter, LED Lighting / Small BLDC Fan Driver, Smart Home End Node (Zigbee Thread BLE Bridge).
IoT Sensor Node
The PIC16LF15344T-I/SS fits IoT sensor nodes through its 1.8 V to 3.6 V operating range and XLP sleep currents below 50 nA, allowing multi-year deployment on a single CR2032 coin cell. The 10-bit ADC samples battery voltage and sensor inputs while the 4 CLC blocks handle autonomous threshold detection without waking the CPU, slashing average power by 30-50% vs polling-based designs. Pair with an SPI-connected temperature/humidity IC and the integrated I2C master handles slave management in sleep mode. The 32 MHz core allows on-chip signal processing between long sleep intervals.
Recommended
Battery-Powered Wearable Health Monitor
The PIC16LF15344T-I/SS suits wearable health monitors because its 18 GPIO pins support multiple biometric sensors while the 4 PWMs drive optical PPG (photoplethysmography) LED chains. The CWG generates precise LED drive waveforms, improving SpO2 measurement accuracy by 10-15% compared to software PWM. Nanoamp sleep current extends battery life to weeks rather than days, and the 32 MHz core runs lightweight heart-rate FFT algorithms in real time. The 20-SSOP footprint enables integration into slim 25 mm diameter wearable enclosures with minimal PCB area.
Recommended
Wireless Remote Control (Sub-GHz/IR)
The PIC16LF15344T-I/SS powers RF/IR remote controls through its 2 EUSART modules - one for the RF transmitter (e.g., Si4455 sub-GHz link) and one for IR protocol generation. The CLC blocks handle button-debouncing and edge detection in hardware, removing the need for polling loops. XLP sleep keeps quiescent current below 100 nA so a remote control survives 5+ years on two AAA cells. The 10-bit ADC reads battery voltage for low-battery LED indication, and 512 B SRAM stores the latest pairing state across resets.
Recommended
Industrial Process Sensor / 4-20 mA Loop Transmitter
The PIC16LF15344T-I/SS drives 4-20 mA industrial loop transmitters using its 10-bit ADC for pressure/temperature sensing and the integrated 5-bit DAC for loop current modulation. Industrial-grade -40C to +85C operation ensures reliability in factory environments. The 2 EUSART ports support HART protocol overlay (1200/2200 Hz FSK) and Modbus RTU simultaneously. CLC peripherals handle HART carrier detection without CPU load, while 32 MHz core executes Modbus message framing. Low 1.8 V operation extends battery life in wirelessHART sensor nodes.
Recommended
LED Lighting / Small BLDC Fan Driver
The PIC16LF15344T-I/SS drives LED lighting and small BLDC fans through its 4 PWM channels and CWG module. The CWG produces complementary PWM outputs with programmable dead-band (50 ns to 200 ns), ideal for half-bridge MOSFET driver control. The 32 MHz PWM resolution at 8-bit gives 125 kHz switching frequency with 1% duty-cycle steps, dimming LEDs below 1% without flicker. Independent PWM triggers from CLC allow autonomous color-mixing without CPU intervention, reducing code complexity and power draw.
Recommended
Smart Home End Node (Zigbee Thread BLE Bridge)
The PIC16LF15344T-I/SS acts as a smart home sensor end node, communicating with a parent Zigbee/Thread/BLE module via UART or SPI. The integrated CLC handles wake-on-radio interrupts, allowing the XLP MCU to remain in deep sleep until the radio module signals an event. The 10-bit ADC reads multiple environmental inputs (light, temperature, occupancy) while the 4 PWMs control local indicators. Sleep currents under 100 nA keep the node on a coin cell for years, and the 32 MHz core runs simple on-device decision logic (e.g., occupancy-triggered lighting).

Key Differentiators
- Wide low-voltage operating range with XLP technology (vs PIC16F15344T-I/SS)
- 4 CLC and CWG blocks for autonomous peripheral logic (vs PIC16LF1513T-I/SS)
- Industry-leading CIP integration at 8-bit level (vs PIC16LF1509-I/SS)
Design Notes
Estimated: at VDD = 3.3 V and active current = 1.5 mA at 32 MHz, the active power is 4.95 mW. In Sleep mode with peripherals disabled, XLP datasheet figures show <50 nA typical at 25C, which is critical for coin-cell longevity. Place a 100 nF decoupling capacitor within 3 mm of the VDD pin and a bulk 1 uF to 10 uF capacitor near the package to handle ADC reference transients.
Use a ground pour on the top layer stitched with multiple vias to the bottom layer under the SSOP-20 footprint. Route the ICSP programming pins (RA0/RA1) to a dedicated 0.1 inch header for in-circuit debugging. The analog AVREF pin should be tied to VDD through a ferrite bead or RC filter (10 ohm + 100 nF) to reduce ADC reference noise by 5-10 dB.
Keep the 32 MHz crystal or external clock traces shorter than 5 mm and shield them with a ground trace to avoid coupling into analog inputs. The CLC and CWG signal lines should be routed away from the ADC inputs - parallel runs longer than 10 mm can introduce 1-2 LSB crosstalk. Use a separate analog ground island connected to VSS at a single point if mixing sensitive analog with switching outputs.
Do not exceed 3.6 V on any pin of the LF variant - the PIC16F version is required for 5 V operation. The MCLR pin (RA3) requires a 10 kohm pull-up to VDD if not driven externally; leaving it floating causes intermittent resets. Disable unused peripherals in firmware via the PMD (Peripheral Module Disable) registers to achieve the lowest sleep current.
Compliance Information
RoHS compliant and lead-free per Component Accessories store listing and Microchip product page. Not AEC-Q100 qualified in this -I/SS variant - automotive applications need a -VAO or -EQ suffix variant. XLP family supports industrial temperature range -40C to +85C.
