PIC16LF15356T-I/SS Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (RAM), non-volatile data memory (EEPROM), and a rich set of peripherals such as timers, ADCs, communication controllers, and I/O. Within the broader taxonomy, the PIC16LF15356 belongs to the PIC16 family (8-bit mid-range) of the PIC microcontroller family, which sits inside the Microchip 8-bit MCU portfolio. The "LF" prefix denotes the low-voltage variant optimized for sub-3.3V operation, and "15356" indicates the specific pin/memory/peripheral configuration.
Key features include four 10-bit PWMs with complementary waveform generation, a 10-bit ADC with computation, a 5-bit DAC, comparators with hysteresis, four Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), two EUSART, SPI, and I2C. The 28KB Flash holds 16K x 14 instruction words, ample for state-machine plus protocol-stack applications. On-chip peripherals handle signal generation and analog sampling, offloading the CPU.
The device employs the PIC16 enhanced mid-range core (14-bit instruction width) with a hardware interrupt controller and peripheral pin select (PPS) for flexible signal routing. XLP technology delivers nanoWatt sleep currents, and IDLE/DOZE modes reduce dynamic power, enabling coin-cell and energy-harvesting duty cycles.
Typical applications include IoT sensor nodes, battery-powered home automation, low-power wireless sensor hubs, consumer handhelds, and industrial sensor interfaces. The combination of CIPs (Core Independent Peripherals) and XLP makes it well-suited to designs where the MCU must remain mostly asleep, waking only briefly to acquire and transmit data.
When designing with this part, choose the LF variant only when your system runs below 3.6V; otherwise prefer the PIC16F15356 for 5V tolerance. Place a 100 nF decoupling capacitor within 5 mm of each VDD/VSS pair, and follow the recommended ICSP connections if in-circuit programming is needed.

Aplicações típicas
PIC16LF15356T-I/SS é adequado para 6 aplicaçãos: Battery-Powered IoT Sensor Node, Home Automation / Smart Home Device, Consumer Handheld Electronics, Industrial Sensor Interface Module, Low-Power Wireless Sensor Hub, LED Lighting Control Module.
Battery-Powered IoT Sensor Node
The PIC16LF15356T-I/SS fits battery-powered IoT sensor nodes because its 1.8 V to 3.6 V operating range and XLP nanoWatt technology deliver deep-sleep currents well below 1 uA, extending coin-cell life. The 28 KB Flash stores a small wireless protocol stack (e.g., LoRaWAN MAC or BLE beacon firmware) alongside sensor-processing code, while 2 KB SRAM handles data buffering. Its 10-bit ADC with computation performs on-chip averaging and threshold comparison, waking the CPU only when needed. The PIC16LF15356T-I/SS integrates SPI/I2C for direct sensor and radio module interfacing without external glue logic, keeping the BOM small. With PPS routing, designers can place peripheral pins flexibly, easing PCB layout in compact wearable form factors.
Recomendado
Home Automation / Smart Home Device
In home automation endpoints such as smart plugs, thermostats, and occupancy sensors, the PIC16LF15356T-I/SS provides enough Flash (28 KB) for Z-Wave or Zigbee application profiles and 2 KB SRAM for packet queues. Two EUSART channels support simultaneous wired UART bridge and debug output. The 4 Configurable Logic Cells (CLC) implement custom glue logic like touch-button encoders or quadrature decoders without external gates. Its low-voltage LF operation supports 2x AA battery remotes directly. The 28-SSOP package fits low-profile wall-switch housings. PPS enables re-routing of UART, SPI, and PWM to any I/O pin, simplifying PCB layout when mechanical constraints force awkward pin assignments.
Recomendado
Consumer Handheld Electronics
Consumer handhelds - e.g., personal care devices, remote controls, and small kitchen appliances - leverage the PIC16LF15356T-I/SS for its tiny 28-SSOP footprint, low power, and rich peripheral set. The Complementary Waveform Generator (CWG) drives piezo buzzers and small motors with dead-band control, eliminating external driver timing circuits. The 10-bit PWM channels manage LED brightness or heating-element control with smooth dimming. The ADC computation block performs oversampling and threshold detection for battery and temperature monitoring, protecting the device and the user. With 32 MHz operation, button-press latency stays under 50 ms even with software debouncing and command parsing. PPS allows the same firmware to be reused across SKUs with different mechanical layouts.
Recomendado
Industrial Sensor Interface Module
In industrial sensor interface modules, the PIC16LF15356T-I/SS acts as the local data-acquisition and protocol-bridge controller. Its 10-bit ADC with computation samples 4-20 mA loop signals or thermocouple-amplified voltages, applies digital filtering on-chip, and forwards results over RS-485 via the EUSART. The two comparators support windowed limit detection for alarm generation without CPU intervention. Industrial temperature grade (-40 C to +85 C) suits factory-floor enclosures. The 28-SSOP package withstands conformal coating and provides good thermal dissipation for continuous operation. With PPS, designers can swap UART, SPI, and PWM assignments without re-spinning PCB artwork when mechanical layouts evolve.
Recomendado
Low-Power Wireless Sensor Hub
The PIC16LF15356T-I/SS is well matched to low-power wireless sensor hubs that aggregate data from multiple nearby sensors over SPI/I2C and forward aggregated payloads over a primary radio. Its 28 KB Flash accommodates small MAC stacks plus an application scheduler, and 2 KB SRAM holds aggregated frames before transmission. CLC cells implement custom wake-up timers and hardware gating that let the radio sleep while the MCU continues to sample. XLP sleep currents extend battery life to multi-year operation in maintenance-free installations. The 28-SSOP industrial temperature grade supports outdoor enclosures across climate zones, and PPS lets the same MCU drive different radio modules (sub-GHz, BLE, LoRa) with minimal firmware changes.
Recomendado
LED Lighting Control Module
For LED lighting control modules - architectural dimmers, RGB controllers, and horticulture fixtures - the PIC16LF15356T-I/SS provides four 10-bit PWM channels that drive LED drivers with smooth 0.1 percent dimming resolution. The CWG adds dead-band control for half-bridge FET drivers in buck and boost topologies, while the comparator implements hysteretic current control for constant-current regulation without firmware intervention. CLC cells can realize a custom logarithmic dimming curve that matches human eye perception, offloaded from the CPU. Operating from 1.8 V to 3.6 V, it can be powered directly from a small auxiliary rail or USB supply. PPS flexibility lets the same firmware drive different LED-driver pinouts across product variants.

Notas de projeto
Place a 100 nF ceramic decoupling capacitor within 5 mm of each VDD/VSS pin pair (pins 1/8 and 20/19 on the 28-SSOP). For battery applications using the XLP sleep modes, also include a 10 uF bulk capacitor on VDD to handle sleep-to-active current transients. Avoid routing high-frequency signals (SPI, PWM) over the VDD pour to minimize injected noise into the analog ADC inputs.
Keep the ICSP programming lines (RB6/ICSPCLK and RB7/ICSPDAT) accessible in the layout - they share pins 22 and 21 on the 28-SSOP and must not be hard-pulled to either rail. Provide a 4.7 kohm pull-up on MCLR (pin 4, RA3) to enable reliable in-circuit programming. Leave at least 0.5 mm clearance between analog and digital traces to minimize ADC coupling.
Do not exceed 3.6 V on any pin of the PIC16LF15356T-I/SS - this is the LF low-voltage variant. For 5 V tolerance use the PIC16F15356 family. When using PPS, do not remap a peripheral to a pin that is also serving as the ICSP data line - programming will fail. Confirm configuration bits are set for the correct oscillator mode before firmware upload, as misconfiguration can lock the part.
