PIC16LF15355T-I/SO Visão geral
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, optimized for low cost, deterministic real-time control, and low power. Within the broader taxonomy, the PIC16LF15355 belongs to: 8-bit MCU -> PIC16 family -> PIC16F153xx sub-family -> XLP low-power class -> general-purpose microcontrollers -> embedded semiconductors. This hierarchy places it above simple 8-bit timers but below 16-bit dsPIC and 32-bit ARM Cortex-M parts in computational capability, while excelling in cost-sensitive, low-power applications.
Key features include four 10-bit PWM outputs, a 10-bit ADC with computation, a 5-bit DAC, comparators, complementary waveform generator (CWG), four configurable logic cells (CLC), two EUSART, SPI, and I2C peripherals. The 'LF' suffix denotes the wide-voltage variant operating from 1.8V to 3.6V, ideal for lithium battery systems. The device includes a peripheral module disable (PMD) feature for granular power gating, an integrated temperature indicator, and eXtreme Low-Power sleep modes down to sub-microamp currents.
The core is Microchip's enhanced mid-range 8-bit CPU with a 49-instruction set, single-cycle hardware multiply, and 32kHz to 32MHz HF internal oscillator. The CIP blocks (CLC, CWG, NCO, PWM) operate without CPU intervention, offloading timing-critical tasks and enabling deeper sleep states. The 14KB self-programmable Flash supports in-field firmware updates via ICSP or bootloader, while the 1024-byte SRAM supports C-callable routines with hardware stack.
Typical applications include battery-powered IoT sensor nodes, low-power wireless remote controls, consumer appliances with capacitive touch interfaces, automotive body electronics (non-safety), portable medical monitors, and industrial sensor hubs. The wide-voltage range and XLP features are particularly attractive for energy-harvesting and primary-cell applications where battery life dominates the design constraint.
When designing with this part, take advantage of the CIP blocks to keep the CPU in sleep mode: configure a CLC-driven ADC wake-up, or use the CWG to generate a complementary PWM for a small motor without CPU intervention. For sub-uA sleep currents, disable unused peripherals via PMD bits, configure all unused pins as outputs low, and select the LFINTOSC at 32kHz for RTC operation rather than the HF oscillator.

Aplicações típicas
PIC16LF15355T-I/SO é adequado para 7 aplicaçãos: Battery-Powered IoT Sensor Node, Consumer Appliance Control, Wireless Remote Control / HMI, Automotive Body Electronics (Non-Safety), Portable Medical Monitoring, Industrial Sensor Hub, Energy Harvesting Sensor.
Battery-Powered IoT Sensor Node
The PIC16LF15355T-I/SO is purpose-built for IoT sensor nodes running from a single lithium primary cell or 2x AA cells. Its 1.8V minimum VDD lets the design operate down to the battery's end-of-life voltage, while XLP nanoWatt technology keeps sleep current under 1 uA typical. The CLC blocks can wake the ADC on a threshold event without CPU intervention, letting the MCU spend 99% of its time in deep sleep. Combined with PMD peripheral gating and 1.8-3.6V operation, the part enables multi-year battery life on coin cells when paired with a low-duty-cycle LoRa or sub-GHz radio.
Recomendado
Consumer Appliance Control
In washing machines, coffee makers, and small kitchen appliances, the PIC16LF15355T-I/SO provides deterministic real-time control of pumps, valves, and displays. The four 10-bit PWM channels drive motor speed or LED dimming without software overhead, while the CWG generates complementary dead-time-controlled signals for small BLDC or H-bridge drivers. The 1KB SRAM supports touch-sensing libraries via the CTMU peripheral, and the wide-voltage operation tolerates rectified mains-derived DC rails. Its 28-SOIC footprint remains hand-solderable for low-volume appliance production.
Recomendado
Wireless Remote Control / HMI
Battery-powered remote controls benefit from the PIC16LF15355T-I/SO's XLP sleep modes and integrated CIPs. A CLC can scan a 4x4 keypad matrix and wake the MCU only on a valid button press, eliminating the need for an external keyboard controller. The 5-bit DAC drives an audio beeper for tactile feedback, and the EUSART/SPI interfaces support 2.4GHz transceivers like the nRF24L01 or BLE modules. With sleep currents around 50-500 nA, a CR2032 cell can power the remote for 5+ years of typical use.
Recomendado
Automotive Body Electronics (Non-Safety)
For non-safety automotive body modules like interior lighting, seat controllers, or window lift modules, the PIC16LF15355T-I/SO provides adequate processing while operating across automotive temperature ranges (-40C to +125C for the E-grade variant). The PWM, ADC, and EUSART blocks handle LED dimming, switch debouncing, and LIN bus communication. Designers targeting AEC-Q100 should select the PIC16F15355T-I/SOVAO automotive-qualified part rather than the industrial-grade 'T-I/SO' variant.
Recomendado
Portable Medical Monitoring
Portable medical devices such as pulse oximeters, thermometers, and pill dispensers benefit from the PIC16LF15355T-I/SO's low-power operation and integrated analog peripherals. The 10-bit ADC with computation (ADC2) performs oversampling and averaging in hardware, reducing firmware complexity for sensor signal conditioning. The 5-bit DAC calibrates sensor offset, and the CLC implements safety interlocks without CPU round-trip latency. With sleep currents under 1 uA, devices run for months on a single AAA cell.
Recomendado
Industrial Sensor Hub
Industrial sensor hubs aggregate 4-20mA, RTD, or thermocouple inputs and forward them via RS-485 or CAN. The PIC16LF15355T-I/SO's two EUSART blocks can run RS-485 and a debug port simultaneously, while its 10-bit ADC with computation oversamples low-frequency sensor signals for noise immunity. The CWG generates excitation pulses for RTD measurement, and the temperature indicator provides cold-junction compensation for thermocouples. Industrial temperature range (-40C to +85C) covers most factory environments.
Recomendado
Energy Harvesting Sensor
Energy-harvesting designs using solar, thermal, or vibration sources pair naturally with the PIC16LF15355T-I/SO. Its 1.8V minimum VDD lets it operate from a single solar cell or a thermoelectric generator's output, while XLP sleep modes under 1 uA let the MCU wait for sufficient harvested energy before executing. The CLC can wake the device on a capacitor-voltage threshold without an external comparator, and the integrated temperature indicator enables energy-aware duty cycling. Combined with a 32kHz LFINTOSC for RTC operation, the part enables fully autonomous sensor nodes.

Notas de projeto
To achieve sub-microamp sleep currents on PIC16LF15355T-I/SO, configure all unused pins as outputs driving low (never leave them as floating inputs). Disable every unused peripheral via the PMD (Peripheral Module Disable) registers before entering SLEEP. Select the LFINTOSC at 32 kHz for RTC operation rather than the HF oscillator. Source: Microchip PIC16(L)F153xx datasheet DS40002366, section 'Power-Saving Modes'. Estimated: typical sleep current with all peripherals disabled is 50-300 nA at 3V.
Place a 100 nF decoupling capacitor as close as possible to both VDD pins (17 and 28) on the 28-SOIC package, with traces less than 3 mm long. Add a 10 uF bulk capacitor at the regulator output. For noise-sensitive ADC applications, place a ferrite bead between the digital VDD and analog AVDD rail if your design routes them separately. Keep the ICSP pins (RB6/RB7) accessible via a 6-pin header for in-circuit programming and debugging.
Do not assume the 32 MHz HFINTOSC is accurate enough for UART communication - the factory calibration is typically +/- 2% across temperature, while UART needs +/- 2-3% for reliable 115200 baud. For UART, use the 16 MHz HFINTOSC with auto-tuning against the EUSART receiver clock, or switch to an external crystal. Avoid using RA0/RA1 as outputs driving high-current LEDs without series resistors - the absolute maximum pin current is 25 mA source/sink. The 'LF' suffix is not just a marketing label - it is mandatory for 1.8V operation below 2.3V.
