PIC16F15344-I/SS Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a rich set of peripherals (timers, communication blocks, ADCs) into one package. The PIC16 architecture is an 8-bit RISC-style core designed by Microchip that uses a 14-bit instruction word and Harvard bus architecture, sitting within the broader 8-bit MCU category and competing against AVR and 8051 families in low-power and cost-sensitive embedded designs.
Key features of this part include eXtreme Low-Power (XLP) technology with IDLE and DOZE modes, peripheral pin select for flexible signal routing, zero-crossing detection on comparators, and on-chip debugging via the ICD interface. The four CLCs allow state-machine-style logic to be implemented in hardware without external glue, reducing BOM cost and CPU overhead in sensor and lighting control designs.
The 32MHz core delivers up to 8 MIPS, while the 10-bit ADC with computation (ADC2) performs automatic averaging, accumulation, and threshold comparison in hardware, offloading the CPU. The CWG block generates complementary PWM with programmable dead-band control, ideal for half-bridge and full-bridge FET drivers in motor control and Class-D audio stages.
Typical applications include battery-powered sensor nodes, IoT edge devices, LED lighting controllers, low-cost motor control (fans, BLDC pumps), home appliances (white goods user interfaces), and human-machine interface panels with capacitive touch driven by CLCs. The 20-pin SSOP footprint is well suited to compact PCBs where 8-pin or 14-pin parts lack sufficient I/O.
When designing with this MCU, mind the 2.3V minimum Vdd for the F (Flash) variant and reserve one I/O for the ICSPDAT/ICSPCLK debug pair to keep MPLAB X ICD in-circuit programming usable in production boards. Adding a 100nF decoupling cap within 3 mm of each Vdd pin and a 10k pull-up on MCLR is mandatory for reliable reset behavior.

Typical Applications
PIC16F15344-I/SS is suitable for 6 applications: Battery-Powered IoT Sensor Node, LED Lighting Controller, Low-Cost BLDC Fan / Pump Motor Drive, Home Appliance User Interface (HMI), Industrial Sensor Transmitter, Automotive Body Electronics (AEC-Q100 sibling).
Battery-Powered IoT Sensor Node
The PIC16F15344-I/SS fits battery-powered IoT sensor nodes because of its XLP eXtreme Low-Power IDLE and DOZE modes, 2.3V minimum Vdd allowing direct 2xAA or Li-MnO2 cell operation, and the ADC2 with hardware averaging that wakes the CPU only on threshold-crossing events. The four Configurable Logic Cells (CLC) implement wake-on-signal patterns without CPU intervention, reducing average current to a few microamps. The 32MHz core delivers 8 MIPS for local edge processing of temperature, humidity, or motion data before EUSART/SPI/I2C transmission, and 7KB Flash accommodates small LoRaWAN or Zigbee MAC stubs. Placed as the main MCU on a coin-cell board, it outperforms discrete timers+ADC solutions by integrating wake logic, communication, and ADC math in one 20-pin SSOP footprint.
Recommended
LED Lighting Controller
The PIC16F15344-I/SS drives LED lighting controllers thanks to its Complementary Waveform Generator (CWG) block with programmable dead-band control, which produces matched complementary PWM signals for half-bridge and full-bridge LED driver topologies without external timing ICs. The four 10-bit PWM channels support dimming and color-mixing across RGBW channels with 1024-step resolution per channel. Its 32MHz core and 7KB Flash fit DMX512, DALI, or simple 0-10V dimming protocols, while the four CLCs implement hardware-based fade curves, freeing the CPU for user-interface tasks. Compared with discrete PWM controllers, this part reduces PCB area by collapsing timing, dimming, and communication into one 20-pin SSOP device.
Recommended
Low-Cost BLDC Fan / Pump Motor Drive
The PIC16F15344-I/SS is well matched to low-cost BLDC fan and pump motor drives because the CWG block generates complementary PWMs with dead-band insertion required for three-phase half-bridges, while the 32MHz core runs sensorless back-EMF zero-cross detection algorithms in real time. Its 10-bit ADC2 with computation offloads BEMF sampling and averaging into hardware, freeing CPU cycles for speed PI control. The 7KB Flash holds sensorless startup ramps and fault handlers, and the 20-pin SSOP footprint keeps the BOM compact for small-diameter fans. Compared with dedicated BLDC controllers, this MCU offers user-tunable acceleration curves and stackable firmware features at one-fourth the cost.
Recommended
Home Appliance User Interface (HMI)
The PIC16F15344-I/SS drives home appliance HMI front panels because the four Configurable Logic Cells (CLC) implement capacitive-touch decoding, button matrix scanning, and rotary encoder quadrature in pure hardware, eliminating external touch ICs and reducing BOM cost. Its 32MHz core and 7KB Flash accommodate display drivers for segmented LCD or low-cost TFT, plus protocol stacks for UART-connected main controllers. Industrial -40C to +85C operation covers dishwasher, oven, and washer environments, while the SSOP-20 footprint stays within tight control-board enclosures. This part is a strong alternative to 32-bit Cortex-M0 designs when the UI logic is fully event-driven and fits within 7KB of Flash.
Recommended
Industrial Sensor Transmitter
The PIC16F15344-I/SS is a strong fit for industrial 4-20mA loop-powered sensor transmitters because its 2.3V minimum Vdd allows operation from a shunt regulator on the loop, while the ADC2 with hardware averaging delivers stable, low-noise measurements of bridge or RTD sensors. The CLC blocks implement zero-cross detection for AC-excitation of strain gauges, eliminating DSP overhead, and the 10-bit DAC drives the 4-20mA loop with HART modulation capability. With 7KB Flash, designers fit linearization tables and HART state machines directly, avoiding external DSP chips. Compared with low-cost Cortex-M0 alternatives, this part offers better low-power IDLE behavior at higher operating temperature ratings.
Recommended
Automotive Body Electronics (AEC-Q100 sibling)
The PIC16F15344 family supports automotive body electronics through its AEC-Q100 qualified -Q1 variants, making this part family a fit for door modules, mirror controllers, lighting nodes, and simple HVAC actuators. The CWG block drives small BLDC motors for HVAC flaps, while the 32MHz core runs LIN stack firmware in 7KB Flash with idle-mode current under 5 uA for key-off standby. The 20-pin SSOP footprint fits tight body-control module enclosures, and the -Q1 variant extends the operating range to AEC-Q100 Grade 1 (-40C to +125C). Designers who prototype with PIC16F15344-I/SS can swap in the -Q1 drop-in for production automotive SKUs without PCB changes.

Key Differentiators
- Higher Flash and SRAM than smaller-sibling drop-in (vs PIC16F15324-I/SS)
- Smaller Flash than larger-sibling drop-in (vs PIC16F15345-I/SS)
- Same die, SMD SSOP versus through-hole PDIP (vs PIC16F15344-I/P)
Design Notes
Estimated: at 32MHz active, Vdd=3.3V, the PIC16F15344-I/SS draws roughly 2.0 mA typical active current. For battery designs, leverage IDLE mode (CPU halted, peripherals running) and DOZE mode (reduced CPU clock) to drop active current below 0.5 mA. Sleep with WDT disabled draws <100 nA typical. A 100nF ceramic decoupling capacitor must sit within 3 mm of each Vdd pin, with a 10uF bulk capacitor on the PCB power rail.
Place the ICSP connector footprint on every production board even if you plan to skip in-circuit debug, because field firmware updates often require ICSP access. The ICSPDAT (RB7) and ICSPCLK (RB6) pins are shared with general I/O; reserve them or isolate via 0 ohm resistors. MCLR pin requires a 10k pull-up to Vdd; do NOT leave MCLR floating, as noise on MCLR triggers spurious resets. Place the decoupling capacitor for Vdd pin 13 on the same side as the IC, not opposite.
Do NOT confuse PIC16F15344-I/SS with PIC16LF15344-I/SS; the F variant runs 2.3-5.5V while the LF variant runs 1.8-3.6V. Driving a 15344 from a 3.0V supply works; driving a 15344LF from 5V damages it. The 'I' suffix means industrial -40C to +85C; 'E' means extended -40C to +125C. Choosing 'I' for oven-rated appliances causes field failures. Pin 1 marker dot orientation differs between SSOP and PDIP; double-check pin 1 location on the mechanical drawing before soldering.
Compliance Information
