PIC16F15354-E/SO Overview
An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, program memory (Flash/ROM), data memory (RAM), and a rich set of peripherals on one die. PIC MCUs use a modified Harvard RISC architecture with a single accumulator (WREG) and a small instruction set optimized for deterministic interrupt response and low power consumption. Within the broader taxonomy, the PIC16F15354 sits in the Microchip PIC16F family -> 8-bit PIC MCUs -> microcontrollers -> embedded processors -> semiconductors, and it is one of Microchip's most feature-dense mid-range 8-bit parts for sensor interfacing and battery-powered designs.
Key features of the PIC16F15354 include four 10-bit PWMs with independent time bases, a 5-bit DAC, a rail-to-rail comparator, a 10-bit ADC with Computation (ADC2), a Complementary Waveform Generator (CWG), four Configurable Logic Cells (CLCs), two EUSART modules, SPI and I2C peripherals, and an on-chip temperature indicator. The device operates from 2.3V to 5.5V, supports 4x PWMs, and integrates a Peripheral Pin Select (PPS) for flexible signal routing. The 28-SOIC package suits industrial and consumer designs that need a moderate IO count with proven through-hole-friendly surface-mount assembly.
Architecturally, the PIC16F15354 uses a 14-bit instruction word, a two-stage pipeline, and a vectored interrupt controller that supports both peripheral and core interrupts. The CIPs (CLC, CWG, NCO, PWM) execute state-machine logic without CPU intervention, allowing the core to remain in sleep for extended periods and reducing average power by orders of magnitude. The ADC2 hardware averaging and oversampling engine offloads signal-conditioning work from the CPU, while the PPS multiplexer lets designers remap digital peripherals to almost any pin for simplified PCB layout.
Typical applications include low-power IoT sensor nodes, battery-powered home automation devices, LED lighting controllers, HVAC fan control, small appliances, USB-to-UART bridges, and general-purpose replacement of legacy 28-pin PIC16 designs. The device's XLP features (IDLE/DOZE modes, ultra-low-power RTC, 30nA sleep current) make it especially suitable for energy-harvesting and wireless sensor endpoints.
When designing with the PIC16F15354, ensure the VDD decoupling network includes a 100nF ceramic capacitor placed within 3mm of the package pins, and use the PPS registers to reassign peripheral functions if board layout forces pin swaps. Always program the Configuration Words (CONFIG1-CONFIG3) to select the correct oscillator, watchdog, brown-out, and code-protect options before code deployment.

Typical Applications
PIC16F15354-E/SO is suitable for 7 applications: Low-Power IoT Sensor Nodes, LED Lighting and PWM Control, Home Appliance Control (HVAC, Fan, Small Appliances), USB-to-UART Bridge / Serial Console, Battery Chargers and Power Management Controllers, Industrial Sensor Signal Conditioning, Automotive Cabin and Body Electronics (Non-Safety).
Low-Power IoT Sensor Nodes
The PIC16F15354-E/SO is well suited for battery-powered IoT sensor endpoints because of its eXtreme Low-Power (XLP) technology, which delivers sub-100 nA sleep currents with the WDT and interrupt-on-change still active. Its 4 Configurable Logic Cells can implement glue logic in hardware, allowing the core to stay asleep while sensor thresholds are checked. Combined with the ADC2 oversampling engine that can run without waking the CPU, the device enables multi-year battery life on a single coin cell, making it a practical choice for temperature, humidity, and occupancy sensors.
Recommended
LED Lighting and PWM Control
The PIC16F15354-E/SO drives LED lighting strips, dimmers, and RGB color-mixing fixtures using its four 10-bit PWM channels and Complementary Waveform Generator (CWG). Each PWM has an independent time base and can be phase-shifted for multi-channel drivers, while the CWG generates complementary outputs with programmable dead-band for half-bridge LED drivers. The Peripheral Pin Select (PPS) lets the designer remap PWM outputs to any digital pin, simplifying PCB layout when channel count or routing constraints change late in the design.
Recommended
Home Appliance Control (HVAC, Fan, Small Appliances)
The PIC16F15354-E/SO fits home appliance controllers because of its 2.3-5.5 V supply range, -40 to +125 C extended temperature grade (E suffix), and integrated peripherals like the CWG for motor commutation and the comparator for zero-cross detection. The 10-bit ADC2 with hardware averaging reads temperature sensors without CPU overhead, while the 4 PWMs drive fan speeds or valve actuators. With 7 KB Flash and 512 B SRAM, the device runs a real-time control loop and a small user interface on a single die, reducing BOM cost in microwave ovens, dishwashers, and ceiling fans.
Recommended
USB-to-UART Bridge / Serial Console
While the PIC16F15354-E/SO does not have native USB, its two EUSART modules and PPS routing make it ideal for a low-cost serial-console or UART-to-logic-level bridge. The 32 MHz internal oscillator with +/-1 percent accuracy supports 115200 baud reliably, and the 5-bit DAC and comparator can implement RS-232 line-voltage monitoring without external glue logic. Combined with the small 28-SOIC footprint and XLP sleep modes, the device works as a low-power debug bridge for portable test equipment and field-service tools.
Recommended
Battery Chargers and Power Management Controllers
The PIC16F15354-E/SO can host a state-machine-based battery charger because the 4 Configurable Logic Cells implement protection logic in hardware without CPU wake-ups. The 10-bit ADC2 monitors battery voltage and current with hardware accumulation, while the rail-to-rail comparator detects over-current events in microseconds. With its 32 MHz core and 8 MIPS throughput, the device also runs a PWM-based buck or boost charger loop. The 28-SOIC package and -40 to +125 C range suit automotive-cabin, e-bike, and power-tool battery packs.
Recommended
Industrial Sensor Signal Conditioning
The PIC16F15354-E/SO excels at industrial sensor front-ends because the ADC2 with computation can oversample 12-bit-equivalent readings from a 10-bit ADC without waking the CPU. The 5-bit DAC and rail-to-rail comparator support 4-20 mA current-loop transmitters, while the EUSART/SPI/I2C ports connect to digital sensors or industrial busses. The CLCs implement HART-style FSK modulation in hardware, reducing firmware burden. With the E temperature grade (-40 to +125 C) and the 28-SOIC's robust lead frame, the device survives factory-floor vibration and thermal cycling.
Recommended
Automotive Cabin and Body Electronics (Non-Safety)
Although the PIC16F15354-E/SO is not AEC-Q100 qualified, its -40 to +125 C extended temperature range and on-chip peripherals support non-safety automotive cabin applications such as interior lighting, seat-position memory, HVAC blend-door control, and accessory timers. The CWG drives half-bridge FETs for small motors, the comparators detect switch positions, and the ADC2 reads multiple analog sensors with hardware averaging. Designers needing formal automotive qualification should migrate to the AEC-Q100-qualified PIC16F15354-Q1 variant from Microchip, which uses the same die.

Design Notes
Place a 100 nF ceramic decoupling capacitor within 3 mm of the VDD pin (pin 20) and a bulk capacitor (>=1 uF) close to the VDD-VSS pair to suppress digital switching noise on the analog reference. For battery-powered designs, configure the PIC16F15354's LFINTOSC and use the regulator's Sleep mode to draw sub-100 nA standby current. Per the Microchip XLP specification, configure the WDT with a long timeout to allow multi-second sleep intervals between sensor reads, and use the on-chip ADC2 with computation to offload oversampling so the CPU can remain asleep.
Route the ICSP pins (RB6/ICSPCLK on pin 27, RB7/ICSPDAT on pin 28) directly to a 5-pin header or test pad so the device can be programmed and debugged in-circuit with a PICkit or MPLAB Snap. Keep the MCLR/VPP line (pin 1) short and away from switching nodes - a 10 kohm pull-up to VDD and a 100 nF cap to VSS prevent spurious resets. Use a ground plane on the bottom layer for thermal dissipation and analog noise immunity, and place the decoupling capacitor between the IC and the MCU's power pin, not the regulator output, to avoid shared-current noise coupling.
Do not leave the MCLR pin floating - the PIC16F15354 requires a valid logic level for normal operation; an absent pull-up causes intermittent brown-out resets. Avoid using both EUSART modules on the same PPS remap set without verifying the pin assignments in the PPSINPUTS/PPSOUTPUTS registers. When migrating code from PIC16F886 or PIC16F1936, note that the 14-bit instruction word is the same but the register map differs in the CLC, CWG, and ADC2 peripheral blocks - always re-validate the header file and linker script.
Compliance Information
RoHS and lead-free per Microchip product page and DigiKey listing. NOT AEC-Q100 qualified - choose PIC16F15354-Q1 automotive variant for AEC-Q100 designs. Halogen-free status not explicitly stated in the verified data; verify with the manufacturer before compliance-critical purchases.
