PIC16F15356-E/SO Overview
An 8-bit microcontroller (MCU) is a small computer on a single integrated circuit containing a CPU, memory (Flash for program, SRAM for data, EEPROM for non-volatile storage), and peripherals. Within the taxonomy of semiconductors, an MCU falls under microcontrollers, which sit between discrete logic ICs and more complex 32-bit microprocessors. PIC microcontrollers use a Modified Harvard RISC architecture and are widely used in embedded control applications where deterministic behavior, low power, and integrated peripherals reduce BOM cost and PCB area.
Key specifications of the PIC16F15356-E/SO include 32 MHz maximum CPU clock, 28KB (16K x 14 words) Flash program memory, 2KB RAM, 256 bytes of EEPROM, and up to 25 I/O pins. The device operates from 2.3V to 5.5V VDD, with eXtreme Low-Power (XLP) features such as sleep currents below 50 nA typical. The 10-bit ADC supports up to 24 channels depending on package, and the integrated 5-bit DAC enables set-point generation without external components.
The PIC16F15356 uses a RISC-based 8-bit core with a hardware multiplier and single-cycle instruction execution at 32 MHz. The CIPs (CLC, CWG, NCO, PWM) execute state-machine operations independently of the CPU, offloading real-time tasks and reducing firmware complexity. eXtreme Low-Power (XLP) technology with nanoWatt XLP and Deep Sleep modes allows battery-powered applications to operate for years on a single cell. The 28-pin SOIC package provides an easy-to-prototype footprint with 0.300 inch body width compatible with hand-soldering and standard development boards.
Typical applications include IoT sensor nodes, home appliances, motor control (BLDC, stepper, brushed DC), LED lighting controllers, industrial sensor interfaces, battery-powered instruments, and automotive body electronics (non-safety). It is a common choice as a general-purpose MCU when designers need a balance of analog peripherals, communication interfaces, and low power consumption.
When designing with the PIC16F15356-E/SO, ensure that the ICSP/PGD/PGC programming pins are accessible for in-circuit programming, decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the package, and respect the VDD ramp requirements (50 us minimum rise time) for proper Power-on Reset behavior. Use Microchip's MPLAB X IDE and XC8 compiler for firmware development.

Typical Applications
PIC16F15356-E/SO is suitable for 6 applications: IoT Sensor Node Controller, BLDC Motor Controller, Industrial Sensor Interface Module, LED Lighting Controller, Home Appliance Control Board, Battery-Powered Handheld Instrument.
IoT Sensor Node Controller
The PIC16F15356-E/SO fits IoT sensor nodes because its 32 MHz CPU, 28KB Flash, and integrated 10-bit ADC2 with Computation (ADC2) handle multi-channel sensor reads while the XLP nanoWatt sleep mode keeps idle current below 50 nA typical. The 2 EUSART ports and SPI/I2C interfaces support simultaneous sensor bus and radio module connections. Use it as the main MCU on a battery-powered environmental sensor with a 2.4 GHz radio daughter board.
Recommended
BLDC Motor Controller
The PIC16F15356-E/SO drives BLDC motors using its Complementary Waveform Generator (CWG) for hardware-generated complementary PWM with dead-band control and 4 PWM channels for variable frequency drive. The 32 MHz instruction rate supports sensorless back-EMF zero-crossing detection at up to 50,000 RPM on small fan motors. Pair with external gate drivers such as the MCP8021 or three-phase MOSFET bridges, and use the integrated comparators for overcurrent protection without external op-amps.
Recommended
Industrial Sensor Interface Module
The PIC16F15356-E/SO is well suited for industrial sensor interface modules because its 4-20 mA loop-powered design with the 10-bit ADC2 and 5/10-bit DAC delivers 0.1% accurate readings of bridge sensors, RTDs, and thermocouples. The -40C to +125C industrial temperature rating covers outdoor and factory-floor environments. The CLC peripherals implement hardware debouncing and threshold detection without CPU overhead, reducing firmware complexity in safety-relevant applications.
Recommended
LED Lighting Controller
The PIC16F15356-E/SO runs multi-channel LED lighting controllers because its 4 PWM channels drive independent dimming outputs at up to 32 kHz PWM frequency, eliminating audible flicker. The 25 I/O pins support keypad, display, and ambient light sensor interfaces. The CLC peripherals combine PWM with sensor inputs to create hardware-based color-mixing state machines that respond to inputs within microseconds, offloading work from the CPU and simplifying the firmware.
Recommended
Home Appliance Control Board
The PIC16F15356-E/SO serves as the main controller on home appliance boards such as washing machines, dishwashers, and microwave ovens where its 28KB Flash holds state-machine firmware plus display drivers and the 32 MHz core runs multiple sensor-scan loops within tight real-time budgets. The 2 EUSARTs connect to user-interface boards and diagnostic serial interfaces simultaneously, while the 4 PWMs drive motor and heater loads. Industrial temperature grade ensures long-term reliability on hot appliance enclosures.
Recommended
Battery-Powered Handheld Instrument
The PIC16F15356-E/SO fits battery-powered handheld instruments because the eXtreme Low-Power XLP sleep mode draws less than 50 nA in Deep Sleep with RAM retention, allowing years of shelf life on a coin cell. The integrated ADC2 with Computation oversamples sensor signals for 14-bit effective resolution without external components. The 2KB RAM holds calibration tables and measurement buffers, while the 28-SOIC package is hand-solderable for prototype builds and small-batch repairs.

Key Differentiators
- Highest memory in the 28-SOIC PIC16F153xx family (vs PIC16F15355-I/SO)
- Industrial -40C to +125C temperature grade in 28-SOIC (vs PIC16F15355-I/SO)
- Core Independent Peripherals (CLC and CWG) integrated (vs PIC16F1516-I/SO)
Design Notes
Decouple VDD with a 100 nF X7R ceramic capacitor placed within 5 mm of pins 8 and 20, plus a bulk 1-10 uF aluminum-polymer capacitor at the board input. The PIC16F15356-E/SO VDD ramp must be at least 50 us rise time to ensure proper Power-on Reset; faster ramps may require the PWRT configuration bit to extend the reset delay. Deep Sleep current is rated below 50 nA typical at 3V with full RAM retention enabled.
Keep the ICSP traces (RB6/PGD and RB7/PGC) short and isolated from switching power lines to avoid programming interference. Place the 32.768 kHz crystal (if used for Timer1) within 5 mm of the RA6/RA7 pins with a ground guard ring. The exposed copper under the SOIC body should not be flooded with a solid ground pour; instead use a hatched pattern to reduce thermal stress on the plastic package during reflow.
Estimated: enabling the ADC without setting the FVR (Fixed Voltage Reference) module first results in the ADC reference defaulting to VDD and reading 0 V on disconnected channels. Always configure FVR and ADC channel selection in the correct ADCON register order before triggering a conversion. Also note that the CLC outputs on RC3/RC4 can collide with the SPI/I2C peripheral pins; disable CLC when using those peripherals to avoid bus contention.
Compliance Information
RoHS compliant per Microchip product environmental compliance page. Industrial temperature grade -40C to +125C but not AEC-Q100 automotive qualified; for automotive body electronics use the PIC16F15356-E/SOVAO variant.
