PIC16LF15356-I/SP Обзор
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and programmable peripherals. The PIC16F/LF153xx family sits in the 8-bit microcontroller segment of Microchip's portfolio, positioned between baseline PIC10/12/16F parts and the 16-bit dsPIC/PIC24/dsPIC33 families, and below the 32-bit PIC32/SAM families. Within that hierarchy, this device is classified as a low-power (LF) general-purpose MCU with Core Independent Peripherals (CIPs).
Key differentiating features include four Configurable Logic Cells (CLCs), a Complementary Waveform Generator (CWG), a 5-bit DAC, two 10-bit ADCs with up to 24 channels, two EUSART, two SPI/I2C, four 10-bit PWMs, three timers, and a comparator. The CLCs and CWG allow hardware state-machine logic and dead-band control without CPU intervention, which is unusual for an 8-bit part at this price.
The device uses the PIC16 enhanced mid-RISC architecture with a 14-bit instruction word, a hardware multiplier, and an 8-level deep hardware stack. The 32 MHz internal oscillator, combined with the 1.8 V minimum supply, lets engineers trade off speed vs. current draw across power rails (XLP Sleep current down to a few tens of nA). The LF suffix means the F-version silicon does not tolerate 5 V inputs; design accordingly.
Typical applications include industrial automation I/O modules, consumer appliance control panels, low-power sensor nodes, battery-powered IoT endpoints, automotive body and lighting subsystems (non-AEC-Q100), and human-machine interface boards with segment displays or small TFTs. The wide peripheral set is a strong fit for motor control and lighting using the CWG and PWMs.
When designing with this device, ensure VDD stays inside 1.8-3.6 V and that any 5 V signals are level-shifted to the rail. The I/Os are 5 V-tolerant only on the F (non-LF) variant; the LF device tolerates VDD on its pins, so pick a level shifter when interfacing to 5 V logic. Always use a 100 nF decoupling cap adjacent to VDD plus a bulk cap on the board.
This page synthesizes distributor pricing, drop-in alternatives within the SPDIP-28 footprint, and practical design notes that go beyond the manufacturer datasheet to help engineers qualify second sources and plan board layouts.

Типичное применение
PIC16LF15356-I/SP подходит для 7 применениеs: Industrial Sensor Node / 4-20 mA Loop, Battery-Powered IoT Endpoint (BLE/Mesh via EUSART), Consumer Appliance Control Panel, LED Lighting Driver / Smart Bulb Controller, Small Motor Control (Brushed DC, BLDC Sensorless), Human-Machine Interface Board (Segment LCD / Buttons), Low-Power Wireless Sensor Board (Sub-GHz / LoRa via SPI).
Industrial Sensor Node / 4-20 mA Loop
The PIC16LF15356-I/SP fits industrial sensor nodes because it combines a 1.8-3.6 V LF supply with two 10-bit ADCs and a 5-bit DAC for analog signal conditioning. The CLCs and CWG handle zero-crossing detection and PWM-driven loop excitation without CPU load, freeing the core for Modbus RTU over RS-485 via the second EUSART. XLP Sleep reduces quiescent current for battery or harvested-power loops, and 28 KB of Flash holds a full Modbus mapping plus calibration tables.
Рекомендуется
Battery-Powered IoT Endpoint (BLE/Mesh via EUSART)
For battery-powered IoT endpoints the LF15356's XLP Sleep in the deep tens of nA keeps quiescent draw low, while two EUSART peripherals can host a host-side UART bridge or a co-processor such as an RN4870/ATBTLC1000 BLE module. The 2 KB SRAM and 28 KB Flash are sufficient for sensor-fusion preprocessing and a small TCP/IP-over-BLE bridge, and the CLC can wake the core on a GPIO event without polling.
Рекомендуется
Consumer Appliance Control Panel
Appliance control panels benefit from the four 10-bit PWMs for LED backlight dimming, the CWG for low-side drive of buzzers, and the comparator for over-temperature detection. The LF voltage range is appropriate for 3.3 V regulated rails common in washing machines and dishwashers, while the 28-SPDIP package is easy to hand-solder during prototyping. The CLCs implement keypad scan logic without burdening the CPU.
Рекомендуется
LED Lighting Driver / Smart Bulb Controller
The PIC16LF15356's CWG with dead-band control plus four PWMs is a strong fit for smart-bulb LED drivers, supporting high-side and low-side MOSFET timing for buck, boost, and SEPIC topologies. The 5-bit DAC sets analog reference levels, the comparators monitor LED current via shunt sense, and XLP Sleep draws tens of nA when the lamp is off - critical for AC-line powered bulbs that need standby in the mW range.
Рекомендуется
Small Motor Control (Brushed DC, BLDC Sensorless)
Motor control applications leverage the CWG for dead-band insertion between high-side and low-side FETs, four PWMs for closed-loop speed control, the 10-bit ADC for back-EMF sensing, and the comparator for zero-crossing detection in sensorless BLDC. The 32 MHz core runs a PID loop at a comfortable rate, and the 2 KB SRAM holds the commutation state machine. The LF voltage range suits 3.3 V systems typical of low-voltage motor boards.
Рекомендуется
Human-Machine Interface Board (Segment LCD / Buttons)
HMI boards using segment LCD or LED indicators benefit from the LF15356's 25 I/O pins, four PWMs for LED brightness, and four CLCs that implement keypad matrix scanning in hardware. The 28 KB Flash holds custom fonts and menus for small appliances; the 256-byte EEPROM stores user preferences across reboots. The 1.8 V minimum supply is compatible with coin-cell powered remote panels.
Рекомендуется
Low-Power Wireless Sensor Board (Sub-GHz / LoRa via SPI)
For LoRa/Sigfox/Sub-GHz sensor endpoints, the LF15356 drives an SPI-connected radio module while sleeping in XLP between transmissions. The two SPIs allow redundant radio plus external flash; the 5-bit DAC and comparator form a wake-on-threshold analog front-end for battery monitoring. The 28-SPDIP package simplifies bring-up and rework for low-volume IoT pilots.

Ключевые отличия
- Highest Flash density in 28-pin SPDIP PIC16F/LF153xx family (против PIC16LF15355-I/SP)
- Identical LF die available in QFN-28 and SOIC-28 packages (против PIC16LF15356-I/ML)
- Direct F-variant drop-in for 5 V designs (против PIC16F15356-I/SP)
Заметки по проектированию
Estimated: at VDD=3.3 V and active mode @ 32 MHz the PIC16LF15356 draws approximately 3-4 mA typical (verify against datasheet DC table). In Sleep with peripherals off the XLP Sleep current drops to tens of nA. Place a 100 nF X7R decoupling capacitor within 2 mm of the VDD pin (pin 25) and a 1-10 uF bulk cap on the supply rail to handle HFINTOSC current transients during wake.
Keep ICSP pins (RB6/RB7) accessible for in-circuit programming. Add a 10 kohm pull-up on MCLR/RA3 (pin 1) to ensure clean reset - the internal weak pull-up is not always reliable with capacitive loading. Reserve a 4.7 kohm pull-up on the I2C SCL/SDA pair if I2C is used in the design. The 28-SPDIP footprint provides generous clearance for hand-rework, which simplifies prototype bring-up.
Do not apply 5 V signals to the LF variant I/O pins - the LF variant is NOT 5 V-tolerant. Use the F variant (PIC16F15356-I/SP, 2.3-5.5 V) or add external level shifters. Verify CONFIG1 LVP (Low-Voltage Programming) bit - if disabled, apply 11-13 V on MCLR for HV programming, otherwise the device will appear dead. When migrating from PIC16F15325/15345/15355 to LF15356, the pinout is identical but the voltage range differs.
Route the OSC1/OSC2 traces short and shielded if an external oscillator is needed; for HFINTOSC-only designs no special layout is required. Group analog ADC inputs together with a ground pour isolating them from PWM output traces to minimize digital switching noise coupling into ADC samples. Place CLC and PWM output traces away from sensitive analog inputs.
Информация о соответствии
Per Microchip product page, the -I/SP variant is industrial temperature grade (-40C to +85C), lead-free, halogen-free, and RoHS compliant. It is NOT AEC-Q100 qualified; choose -EQ1 suffix for automotive.
