PIC16LF15355T-I/SS 개요
An 8-bit MCU is a single-chip computer built around an 8-bit data-path CPU, on-board non-volatile program memory, working SRAM, and a set of digital/analog peripherals. PIC microcontrollers use a Harvard RISC architecture with a small, deterministic instruction set and on-chip Flash, sitting in the device hierarchy as: PIC16 -> 8-bit MCU -> microcontroller -> embedded computing -> semiconductor. The 'LF' suffix denotes a wide-voltage 1.8V to 5.5V operating range with picoPower/XLP Sleep currents.
Key features include four 10-bit PWM outputs, a 10-bit ADC, a 5-bit/8-bit DAC, a comparator, the Configurable Logic Cell (CLC) peripheral, the Complementary Waveform Generator (CWG), two EUSART modules, and SPI/I2C. The XLP Sleep mode draws a few tens of nanoamperes, which is a major advantage versus legacy mid-range PIC16 parts for battery-powered sensor nodes.
The PIC16LF15355 uses an enhanced mid-range core with a hardware multiplier, interrupt-driven I/O, and peripheral pin select (PPS) for flexible pin mapping. PPS lets designers remap digital peripherals to a wide range of I/O pins, simplifying PCB routing. The CWG, NCO, and CLC provide hardware-based waveform and state-machine functions that offload timing-critical tasks from the CPU.
Typical applications include low-power IoT endpoints, sensor and HVAC transducer nodes, LED lighting controllers, consumer appliances, and small industrial control boards. The combination of analog (ADC, DAC, comparator), digital (CLC, CWG, timers), and serial (EUSART/SPI/I2C) peripherals covers most mixed-signal tasks.
When designing with this device, mind the Flash/RAM ratio and peripheral set versus application code size. Use MPLAB X IDE with XC8 compiler and MPLAB Code Configurator (MCC) to generate peripheral drivers and pin maps.

일반적인 애플리케이션
PIC16LF15355T-I/SS 적합 용도: 6 애플리케이션s: Battery-Powered IoT Sensor Node, HVAC Environmental Transducer, LED Lighting Controller, Consumer Appliance User Interface Board, Small Industrial Control / Sensor Hub, Portable Medical / Wellness Device.
Battery-Powered IoT Sensor Node
The PIC16LF15355T-I/SS is well-suited for wireless sensor endpoints due to its 1.8V to 5.5V VDD range and XLP Sleep currents in the tens of nanoamperes, which directly extend coin-cell battery life. With 14 KB Flash it fits application firmware for periodic sensor reads plus small BLE/Zigbee stacks, while the four CLC blocks and one comparator offload timing-critical events like wake-on-threshold in hardware. Place the device on a 28-SSOP land pattern with a 100 nF decoupling cap adjacent to VDD pin 1; pair with a sub-GHz or BLE module on the EUSART/SPI pins for the radio link. Compared to legacy mid-range PIC16 parts, the LF variant adds wide-voltage Sleep and PPS, which simplifies mixed 1.8V/3.3V rail designs.

HVAC Environmental Transducer
The PIC16LF15355T-I/SS fits HVAC transducer modules that digitize temperature, humidity, and pressure sensors because its 10-bit ADC and 5/8-bit DAC plus one on-chip comparator form a complete analog front-end in a single chip. The 32 MHz core and 1 KB RAM run compensation math at sub-millisecond intervals, while XLP Sleep keeps idle power under 1 uA between samples. Mount the SSOP-28 package near the sensor with a low-impedance ground pour; route the EUSART pins to the host controller over RS-485 or SPI. The wide 1.8V-5.5V supply allows direct connection to 3.3V or 5V transducer boards without a separate LDO.
추천
LED Lighting Controller
The PIC16LF15355T-I/SS drives multi-channel LED fixtures via its four 10-bit PWM channels and the CWG peripheral, which generates complementary PWM outputs with programmable dead-band for half-bridge LED drivers. With 14 KB Flash the controller fits color-mixing algorithms, DMX/art-net input parsers, and dimming curves, while PPS remaps PWM and CWG outputs to almost any I/O pin for flexible PCB routing. The LF voltage range accepts 3.3V digital rails and 5V analog LED-driver rails from a single supply. The four CLC blocks implement blanking, fault-masking, and over-current latching in hardware, freeing CPU cycles for the lighting control loop.
추천
Consumer Appliance User Interface Board
The PIC16LF15355T-I/SS fits appliance UI boards that drive 7-segment displays, keypads, and indicator LEDs because its 14 KB Flash stores multi-language UI state machines and the CWG peripheral creates the beeper/buzzer waveforms. PPS enables flexible keypad scanning on any GPIO, and 1 KB SRAM holds menu buffers and timer flags. The industrial -40C to +85C temperature grade covers kitchen and laundry environments. The 28-SSOP package simplifies hand-rework during prototyping and accepts a wide 1.8V-5.5V supply to share rails with the appliance main board.
추천
Small Industrial Control / Sensor Hub
The PIC16LF15355T-I/SS serves as a sensor-hub MCU on industrial boards, aggregating analog/digital sensors over SPI/I2C and exposing results via EUSART (RS-232/485) or SPI. The four CLC blocks implement hardware interlocks for safety I/O without firmware polling, and the NCO provides a 16-bit precision pulse train for stepper or valve timing. The 1.8V-5.5V supply accepts both 3.3V digital and 5V sensor rails. Industrial temp grade and 14 KB Flash accommodate protocol stacks like Modbus RTU plus a small HMI parser.
추천
Portable Medical / Wellness Device
The PIC16LF15355T-I/SS powers portable wellness devices such as pulse oximeters, thermometers, and glucose meters where low-power Sleep between measurements dominates battery life. XLP Sleep below 100 nA combined with a 1.8V minimum supply lets devices run for years on a single coin cell. The 10-bit ADC and on-chip comparator measure biopotential and optical sensor signals with no external signal chain, and 14 KB Flash stores calibration tables and measurement history. The 28-SSOP accepts both 1.8V sensor rails and 3.3V display rails. The CLC blocks implement hardware debouncing on user buttons, reducing firmware overhead.

주요 차별점

- Tape & Reel packaging for SMT assembly (vs PIC16LF15355-I/SS)
설계 노트
The PIC16LF15355T-I/SS supports a wide 1.8V to 5.5V supply, but XLP Sleep current is only met with a clean, well-bypassed VDD rail. Place a 100 nF ceramic decoupling capacitor within 3 mm of VDD (pin 1) and a bulk 1 uF to 10 uF capacitor near the SSOP package. For Sleep currents below 1 uA, disable the BOR and WDT modules in firmware configuration bits and avoid floating I/O pins, which can leak several hundred nA total.
Route the ICSP pins (PGC/PGD on RB6/RB5) to a 4-pin or 5-pin header with series resistors or direct connections per Microchip ICD/Pickit recommendations. Keep the ICSP traces short and away from switching converters. For PPS-mapped peripherals, group related signals together (e.g., SPI signals on adjacent PORTB pins) to minimize skew on high-speed lines like SPI at 8 MHz or higher.
Do not assume all PIC16LF15355 datasheet parameters apply at 1.8V - many peripherals like the ADC and PWM have reduced accuracy below 2.0V. Always check the parametric curve in the datasheet for your target VDD. Also, the configuration bits for oscillator selection default to HFINTOSC; if you switch to an external crystal, configure the OSCCON register correctly or the device will not start. Estimated: at 32 MHz and 3.3V, typical Icore is around 4 mA active per the family datasheet.
