PIC16F15355-I/SO Übersicht
An 8-bit microcontroller (MCU) is a compact single-chip computer that integrates a CPU, Flash program memory, RAM, EEPROM, and a set of peripherals onto one silicon die. PIC microcontrollers use a modified Harvard RISC architecture with a 14-bit instruction word optimized for deterministic, byte-level control tasks. The PIC16F15355 belongs to the PIC16F153xx family, sitting in the hierarchy: 8-bit PIC microcontroller -> Microchip PIC16 family -> enhanced mid-range core -> general-purpose embedded controller. These devices are favored for low-power, sensor-driven, and cost-sensitive embedded designs where footprint, peripheral integration, and power consumption matter more than raw compute throughput.
Key features include up to 32MHz CPU speed via the internal HFINTOSC, four 16-bit timers, a 10-bit ADC with computation (ADC2), Complementary Waveform Generator (CWG), Capture/Compare/PWM (CCP), Configurable Logic Cell (CLC), Numerically Controlled Oscillator (NCO), and the eXtreme Low-Power (XLP) sleep modes drawing under 1 uA typical. The 28-SOIC package is a wide-body, 1.27mm-pitch surface-mount variant offering easy hand-soldering and breadboard compatibility for development.
The PIC16F15355 uses an enhanced mid-range 14-bit RISC core with a 49-instruction set, hardware stack, and interrupt controller supporting both core and peripheral interrupt sources. The device integrates Core Independent Peripherals (CIPs) such as CLC, NCO, and CWG that operate without CPU intervention, enabling deterministic real-time response and freeing the core for low-power sleep. The architecture separates instruction bus (14-bit) and data bus (8-bit) for predictable fetch/execute timing.
Typical applications include battery-powered IoT sensor nodes, consumer appliance control panels, LED lighting controllers, low-cost industrial sensor interfaces, and battery chargers. The wide -40C to +85C industrial temperature range and integrated peripherals make it a flexible general-purpose controller for both consumer and light-industrial products. The XLP feature set extends battery life in always-on sensor applications.
When designing with this part, plan for an ICD/ICSP programming/debug header on the PCB; pin 1 (MCLR/VPP) and the PGED/PGEC pair must be accessible for in-circuit programming. Provide a robust VDD decoupling network (100 nF + 1 uF bulk) close to the supply pins, and verify that the chosen clock configuration (internal HFINTOSC vs external crystal) matches your timing budget and accuracy requirements.

Battery-Powered IoT Sensor Node
The PIC16F15355-I/SO is well-suited for battery-powered IoT sensor nodes where standby current dominates lifetime. Its XLP sleep modes draw under 1 uA typical, allowing duty-cycled wake to sample a sensor and transmit via UART or SPI before returning to sleep. The 32MHz HFINTOSC provides fast wake-and-execute cycles without external crystal cost. The 10-bit ADC with computation (ADC2) enables averaging and threshold detection without CPU load, while the 14KB Flash stores sensor calibration, edge AI lite algorithms, and protocol stacks. Operating from 2.3V-5.5V VDD covers single-cell Li-ion (3.0-4.2V) and two-cell alkaline (2.0-3.2V) configurations.
Empfohlen
Consumer Appliance Control Panel
The PIC16F15355-I/SO fits consumer appliance control panels that need deterministic response, low cost, and broad peripheral integration. The Complementary Waveform Generator (CWG) drives MOSFET half-bridges for motor and valve control, while CCP and 16-bit timers generate PWM for LED indicators and backlights. The CLCs let designers wire combinational logic in hardware for safety interlocks without software round-trip delays. With 14KB Flash, the firmware can hold UI state machines, fault diagnostics, and energy-metering routines. The 28-SOIC package is hand-solderable for low-NIC prototypes before committing to reflow SOIC production.

LED Lighting Controller
For LED lighting controllers requiring smooth dimming and color-mixing without flicker, the PIC16F15355-I/SO provides multiple PWM channels via CCP and CWG peripherals. The 32MHz core supports high-resolution PWM (up to 16-bit effective) for >1000:1 dimming ratio, while the NCO (Numerically Controlled Oscillator) generates frequency-stable tones for control signal decoding. The 14KB Flash stores DMX/RDM or DALI protocol stacks plus custom CCT curves. Operating temperature up to +85C handles enclosed luminaire thermal environments. The wide 2.3V-5.5V VDD range supports both 3.3V logic-level LED drivers and 5V analog driver ICs.

Low-Cost Industrial Sensor Interface
Industrial sensor interfaces benefit from the PIC16F15355-I/SO industrial -40C to +85C temperature range and Core Independent Peripherals. The CLC, NCO, and CWG run in hardware without CPU intervention, enabling sub-microsecond deterministic response for safety and control loops. The 10-bit ADC2 with computation performs oversampling and averaging on analog sensor channels, reducing noise on 4-20mA or 0-10V transducer inputs. UART/SPI/I2C peripherals handle Modbus RTU, IO-Link, or proprietary sensor protocols. The 14KB Flash supports calibration tables, linearization curves, and diagnostic logs in a robust wide-temperature part.
Empfohlen
Battery Charger Controller
The PIC16F15355-I/SO is well-matched to standalone battery charger controllers for Li-ion, NiMH, and lead-acid chemistries. The 10-bit ADC2 with computation monitors charge current and voltage with hardware oversampling, while CCP/CWG generate the PWM gate drive for buck or buck-boost power stages. The 32MHz internal oscillator provides accurate timing for CC-CV charge state transitions. With 14KB Flash, the firmware can store chemistry profiles, fuel-gauging state machines, and protection logic. The 2.3V-5.5V VDD range covers single-cell Li-ion USB-powered chargers and 12V solar charge controllers.
Empfohlen
Wearable Health Monitor
Wearable health monitors benefit from the PIC16F15355-I/SO combination of XLP deep-sleep currents under 1 uA and CIP peripherals that operate without waking the CPU. The 10-bit ADC2 samples heart-rate, SpO2, or temperature sensors in hardware-triggered sequences, only waking the core for abnormal-event processing. The 28-SOIC wide-body package is hand-solderable for prototype runs and supports 1.27mm-pitch PCB layouts. UART and I2C peripherals connect to BLE modules or display drivers. The industrial -40C to +85C temperature rating covers the full wearable operating envelope including skin-worn and cold-weather scenarios.

Designhinweise
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 20) of the PIC16F15355-I/SO, with a 1 uF bulk capacitor on the same supply rail near the MCU. Both VSS pins (10 and 19) must be connected to the ground plane with short, low-inductance traces. Provide a dedicated ICSP header footprint (or at minimum test points) for the MCLR/VPP (pin 1), PGD (pin 18), and PGC (pin 17) signals to enable in-system programming and debugging throughout the product lifecycle.
Do not leave the MCLR pin floating; tie it to VDD through a 10 kohm pull-up resistor for proper reset behavior. For ICSP programming, the resistor must be sized to allow the programmer to drive the pin low - 10 kohm is the typical Microchip-recommended value. Also confirm the chosen configuration word disables any peripherals multiplexed onto the PGD/PGC pins before enabling ICSP, or debug sessions will fail to connect reliably.
Select the HFINTOSC configuration carefully for active-power vs accuracy trade-offs. According to the Microchip PIC16F15355 datasheet, the 32 MHz HFINTOSC is factory-trimmed to within a few percent, but for time-sensitive protocols (UART at high baud rates, PWM motor control) select the HFINTOSC with the PLL or switch to an external crystal on OSC1/OSC2 pins (RA6/RA7). The XLP sleep modes drop current to under 1 uA typical when properly configured with all peripherals off.
Keep analog signal traces short and routed away from digital switching signals to minimize ADC2 noise coupling. Place the ADC reference voltage bypass capacitor (typically 100 nF) directly at the AVref pin if used, or rely on the internal FVR with adequate supply decoupling. For SOIC-28, allow at least 1.5 mm clearance between analog and digital copper pours, and use a ground guard ring around analog inputs for highest ADC accuracy.
