PIC16F15355-E/SS Overview
An 8-bit microcontroller (MCU) is a small, low-power computing core with on-chip Flash, RAM, peripherals, and I/O, used to sense, control, and communicate in embedded systems. Within the broader semiconductor hierarchy, an MCU sits under microcontroller -> embedded processor -> semiconductor device. The PIC16F153xx family adds Core Independent Peripherals (CIPs) such as CLC, CWG, and configurable logic to offload timing-critical tasks from the CPU.
Key features of the PIC16F15355-E/SS include 4 PWM channels, 2 comparators, a 5-bit DAC, a 10-bit ADC with up to 24 channels, 4 Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG), and 2 EUSART peripherals supporting SPI and I2C. The eXtreme Low-Power (XLP) technology enables nanoWatt sleep currents in the order of tens of nA, allowing battery-powered nodes to run for years on a single cell.
Architecturally, the device uses an enhanced mid-range 8-bit RISC core with a hardware multiplier, a 31-level hardware stack, and interrupt-driven CIP peripherals that operate without CPU intervention. The combination of 14KB self-programmable Flash and a wide peripheral set lets designers implement mixed-signal front-ends in firmware without external glue logic.
Typical applications include low-power IoT sensor nodes, consumer appliances, LED lighting control, battery-operated handheld instruments, motor control signal conditioning, and industrial sensor interface boards. The wide memory and rich analog/mixed-signal peripherals make it well suited as a system supervisor or signal-conditioning MCU.
When designing with this MCU, plan pin assignments early - the 28-SSOP exposes most I/Os but multiplexing of analog and CIP functions requires careful PPS configuration. Always enable the watchdog timer and use the fail-safe clock monitor for unattended deployments.

Typical Applications
PIC16F15355-E/SS is suitable for 6 applications: Battery-Powered IoT Sensor Node, Consumer Appliance Control Board, LED Lighting Control, Industrial Sensor Interface Board, Motor Control Signal Conditioning, Battery-Operated Handheld Instrument.
Battery-Powered IoT Sensor Node
The PIC16F15355-E/SS fits battery-powered IoT sensor nodes because of its XLP nanoWatt sleep currents (typically under 50 nA with RTC running) and its 32 MHz / 8 MIPS core that wakes, processes, and returns to sleep in microseconds. The 24-channel 10-bit ADC with computation handles temperature, humidity, and analog sensor reads, while the 4 CLC cells and CWG peripheral execute sensor-timing tasks without CPU load. Pin-compatibility with the larger-Flash PIC16F15356-E/SS allows field upgrades to add OTA bootloaders without hardware changes, and the 28-SSOP occupies only ~75 mm^2 of PCB area - well below the footprint of competing Cortex-M0+ designs.
Recommended
Consumer Appliance Control Board
The PIC16F15355-E/SS suits consumer appliance control boards because its 14 KB Flash supports graphical LCD menus, its 4 PWM channels drive motor and LED loads directly, and its 2 EUSART interfaces talk to main MCUs or Wi-Fi modules. The 5-bit DAC and 2 comparators enable closed-loop control of temperature or current sensors without external analog ICs. Compared to using a 32-bit MCU, the PIC16F15355-E/SS cuts BOM cost by 30-40% while the extended -40C to +125C grade handles kitchen and laundry thermal environments. The 28-SSOP is hand-solderable for low-volume production runs.
Recommended
LED Lighting Control
The PIC16F15355-E/SS drives dimmable LED lighting designs through its 4 PWM channels and complementary waveform generator (CWG), which generates center-aligned, dead-band-controlled half-bridge gate signals for buck or boost LED drivers. The 4 Configurable Logic Cells (CLC) implement hardware-only PWM modulation and fault shutdown, offloading the CPU to run DMX-512 or DALI protocol stacks in software. XLP low-power idle reduces standby to under 1 uA for ENERGY STAR-compliant off-mode, and the extended -40C to +125C grade survives outdoor fixture thermal cycling.
Recommended
Industrial Sensor Interface Board
The PIC16F15355-E/SS serves industrial 4-20 mA sensor interface boards through its 24-channel 10-bit ADC, 2 analog comparators with internal DAC reference, and 2 EUSART ports for RS-485 link. The 14 KB Flash fits MODBUS RTU or IO-Link device stacks, while CLC and CWG cells implement HART-style FSK modulation without CPU overhead. The extended -40C to +125C grade handles factory-floor thermal cycling, and the 28-SSOP supports conformal-coated industrial PCBs. Pin-compatibility with the larger-Flash PIC16F15356-E/SS lets one PCB support multiple firmware SKUs.
Recommended
Motor Control Signal Conditioning
The PIC16F15355-E/SS handles motor control signal conditioning through its Complementary Waveform Generator (CWG) producing dead-band-controlled complementary PWM outputs, 4 PWM channels driving independent phases, and 2 comparators with internal DAC implementing hardware overcurrent protection. The 10-bit ADC samples back-EMF and phase current at 100 ksps for sensorless BLDC commutation. The extended temperature grade supports under-hood automotive and industrial motor environments, while the XLP idle current keeps quiescent draw low for battery-powered robotic tools.
Recommended
Battery-Operated Handheld Instrument
The PIC16F15355-E/SS powers handheld measurement instruments where its 14 KB Flash holds calibration tables and UI state machines, its 32 MHz core delivers responsive LCD refresh, and its XLP nanoWatt sleep enables 1+ year shelf life on AA cells. The 10-bit ADC with computation handles sensor linearization, while the EUSART ports link to BLE modules for wireless data export. The 28-SSOP is hand-solderable for prototype builds, and the extended temperature grade lets instruments survive field conditions from winter surveys to summer attic inspections.

- Core Independent Peripherals (CIP) reduce CPU load (vs PIC16F18855-I/SS)
Design Notes
Estimated: at 32 MHz active and 5 V supply, the PIC16F15355-E/SS core draws approximately 5 mA, plus peripheral current. Enable XLP Sleep mode between sensor reads to drop quiescent current below 50 nA. Use the Internal Low-Frequency RC oscillator (31 kHz) for sleep intervals and switch to HFINTOSC only for active processing. A 10 uF bulk + 0.1 uF ceramic bypass cap directly on the VDD pin is recommended per the Microchip datasheet DS40001872.
Route the MCLR/VPP pin through a 10 kohm pull-up to VDD and place a 100 nF cap to ground for in-circuit serial programming (ICSP). Keep analog ADC traces short and away from PWM/digital switching lines; the 28-SSOP package has dedicated analog power pins on VDD/VSS pairs. Use a ground pour on the top layer stitched with vias around the IC to minimize ADC digital-switching noise coupling.
Do not exceed the absolute maximum rating of 5.5 V on VDD - the PIC16F15355-E/SS is NOT 5V tolerant on I/O when running at 3.3V. Always configure unused I/O pins as outputs low to minimize sleep current. The PPS (Peripheral Pin Select) module must be unlocked (PPSLOCK = 0) before reassigning peripheral functions, or writes silently fail. Enable the watchdog timer (WDT) with a 1-second timeout for unattended deployments.
Place a 0.1 uF decoupling capacitor within 3 mm of every VDD pin. For the 28-SSOP, this means pins 1 and 18. Use wide traces (at least 0.3 mm) for VDD/VSS to handle peak transient currents during PWM and EUSART transmissions. Keep the crystal or external oscillator traces short (<10 mm) and surround them with a ground guard ring if high-accuracy ADC sampling is required.
Compliance Information
RoHS and REACH compliant per Microchip product page. The PIC16F15355-E/SS is not AEC-Q100 qualified; for AEC-Q100 automotive grade, use the PIC16F15355-E/SSVAO variant on the Site MPN list. Lead-free (Pb-free) reflow profile per JEDEC J-STD-020.
