PIC16F15354-E/SP Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable peripherals. The PIC16F family sits at the entry-level of Microchip's 8-bit portfolio and is widely used in cost-sensitive, low-power embedded systems. Within the broader taxonomy, this part belongs to: microcontroller -> 8-bit MCU -> PIC16 family -> PIC16F153xx sub-family -> power management and general-purpose embedded control.
Key features include Core Independent Peripherals (CIPs) such as four Configurable Logic Cells (CLCs), a Complementary Waveform Generator (CWG), and four 10-bit PWMs with hardware-driven timing. The device integrates a 5-bit and 10-bit Digital-to-Analog Converter (DAC), multiple comparators, and two EUSART plus SPI/I2C communication interfaces, reducing the need for external components in mixed-signal designs.
The PIC16F15354 uses a Harvard RISC architecture with a 14-bit instruction word, providing deterministic interrupt latency and efficient code density. Its nanoWatt XLP technology delivers sleep currents in the sub-microamp range, and the integrated Peripheral Module Disable (PMD) allows unused peripherals to be individually powered down. The device also includes a Device Information Area (DIA) and Unique ID for traceability in safety or calibration-sensitive applications.
Typical applications include IoT sensor nodes, battery-powered industrial sensors, low-cost motor control (small DC fans, pumps, and BLDC drivers using PWM and CWG), home appliances with user interfaces, lighting controllers, and consumer electronics such as remote controls or smart-home hubs. The wide operating voltage (2.3V-5.5V) makes it directly compatible with both 3.3V and 5V system rails.
When designing with this MCU, plan I/O assignments early because the 25 I/O pins must be shared among analog inputs, communication peripherals, and PWMs. Use the MPLAB X IDE with XC8 compiler for firmware development, and refer to the family datasheet for full register maps and CIP configuration details. Migration between SPDIP, SOIC, and QFN variants is pin-compatible within the PIC16F15354 sub-family.

Typical Applications
PIC16F15354-E/SP is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, Small Motor and Fan Speed Control, Home Appliance User Interface Controllers, LED Lighting Controllers and Dimmers, Industrial Sensor and Process Transmitters, Consumer Electronics Remote Controls and Hubs.
Battery-Powered IoT Sensor Nodes
The PIC16F15354-E/SP's nanoWatt XLP technology delivers sub-microamp sleep currents, making it ideal for IoT sensor nodes that spend most of their time idle. Its 10-bit ADC supports direct connection to analog sensors (temperature, humidity, gas), and the 2.3V minimum supply lets the MCU run directly from a single 3V coin cell. The four CLCs (Configurable Logic Cells) and CWG (Complementary Waveform Generator) enable event-driven wake-ups without CPU intervention, further reducing average power. At 32 MHz, the CPU can process sensor data bursts quickly before returning to sleep. The 25 I/O pins accommodate multiple sensor channels and a wireless module interface (SPI or UART).
Recommended
Small Motor and Fan Speed Control
The PIC16F15354-E/SP's four 10-bit PWM channels and integrated Complementary Waveform Generator (CWG) deliver the precise timing needed for small DC motor and brushless DC fan control. The CWG generates complementary PWM pairs with hardware dead-band control, eliminating CPU overhead for switching. Two EUSARTs and one SPI allow connection to external motor driver ICs or feedback encoders. The integrated comparators and op amps (on select family members) support current sensing for closed-loop control. With 32 MHz CPU and 8 MIPS throughput, the MCU can run PID control loops with sub-millisecond cycle times.
Recommended
Home Appliance User Interface Controllers
In home appliances (washing machines, microwaves, dishwashers), the PIC16F15354-E/SP serves as a low-cost user-interface controller that drives LED/LCD displays, reads capacitive touch or button inputs, and communicates with the main appliance MCU. The 25 I/O pins support matrix keypads, LED arrays, and rotary encoders simultaneously. The integrated 5-bit DAC and PWM channels drive simple audio feedback (buzzers) or backlight dimming. The -40C to +125C operating temperature ensures reliable operation in kitchens, laundry rooms, and garages where ambient temperatures can swing widely.
Recommended
LED Lighting Controllers and Dimmers
The PIC16F15354-E/SP's four 10-bit PWMs and CWG enable flicker-free dimming of constant-current LED strings via PWM-to-analog conversion. The integrated 10-bit DAC generates reference voltages for analog dimming interfaces (0-10V). EUSART and I2C support connectivity to DMX, DALI, or wireless lighting gateways. The 5-bit DAC enables logarithmic dimming curves that match human eye perception without CPU-intensive math. Sleep current below 1 uA means standby power for always-connected lighting fixtures remains under regulatory limits.
Recommended
Industrial Sensor and Process Transmitters
Industrial 4-20 mA loop-powered transmitters benefit from the PIC16F15354-E/SP's wide 2.3V-5.5V supply range and low-power operation. The 10-bit ADC with multiple channels can read bridge sensors (pressure, load), RTDs, or thermocouples via external front-ends. The integrated 5/10-bit DAC supports HART or 0-10V analog outputs. Two EUSARTs provide isolated RS-485 and diagnostic UART outputs. The industrial -40C to +125C temperature rating allows deployment in unheated cabinets and outdoor process plants.
Recommended
Consumer Electronics Remote Controls and Hubs
The PIC16F15354-E/SP is a cost-effective choice for IR/RF remote controls and smart-home hub interfaces. Its low sleep current (under 1 uA with XLP) gives coin-cell remotes multi-year battery life. The integrated comparators wake the MCU on button press without external components. EUSART plus SPI/I2C connect to BLE/Zigbee modules or to host processors. The 25 I/O pins support matrix keypads, IR LEDs (via PWM), and feedback buzzers simultaneously. The small SPDIP package is breadboard-friendly for prototyping consumer product designs.

Design Notes
Decouple VDD/VSS pairs with 100 nF ceramic capacitors placed within 5 mm of each VDD pin. For noise-sensitive analog applications (ADC, DAC, comparators), add a 10 uF bulk capacitor near the MCU. The two VDD pins (19 and 28) and two VSS pins (7 and 18) must each be connected; leaving either VDD floating causes erratic behavior. For battery-powered designs, the IDLE mode with peripherals running draws roughly 30-50 uA at 32 MHz, while SLEEP with WDT draws under 1 uA thanks to XLP technology.
Keep the analog input traces short and route them away from PWM and PWM-switching traces to minimize ADC noise coupling. Use a ground plane under the MCU and avoid routing digital signals across the analog pins. Place the MCLR pull-up resistor (typically 10 kOhm) close to the MCU pin, and consider adding a diode from MCLR to VDD for ESD protection. The 28-pin SPDIP through-hole footprint allows easy double-sided PCB layouts with full ground pours on both sides.
PPS (Peripheral Pin Select) on PIC16F15354 is locked after first programming - design the peripheral-to-pin map early and verify in code. The EUSART and MSSP peripherals share PPS slots, so concurrent use of multiple communication interfaces requires careful pin assignment. The internal oscillator is factory-trimmed but for UART applications requiring baud-rate accuracy better than 1%, use an external crystal or the OSCTUNE register with calibration. Note that the 5-bit DAC and 10-bit DAC share registers and cannot output simultaneously.
The PIC16F15354-E/SP's I/O pins source/sink up to 25 mA per pin (with 200 mA total package limit). For driving LEDs or relays directly, use a current-limiting resistor and verify total package dissipation does not exceed thermal limits. When driving long cables (RS-485, sensor lines), add series termination resistors (33-100 ohm) close to the MCU pin to dampen ringing. The Schmitt-trigger inputs are tolerant of slow edges, but signals above 1 MHz benefit from 10-33 pF of capacitive loading to slow the edges and reduce EMI.
Compliance Information
RoHS and REACH compliance per Microchip product page. Industrial-grade part (-40C to +125C), not AEC-Q100 qualified - use automotive-qualified PIC16F15354-E/SP-VAO variant for AEC-Q100 requirements.
