PIC16F15355-I/MV Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals. Within the broader semiconductor taxonomy, an MCU belongs to the category of embedded processors -> microcontrollers -> 8-bit microcontrollers -> PIC microcontrollers. The 8-bit PIC architecture from Microchip uses a modified Harvard RISC core optimized for deterministic real-time control with a small instruction set and single-cycle execution for most instructions.
Key features of the PIC16F15355-I/MV include 14KB self-programmable Flash (8K x 14 words), 512B RAM, 256B EEPROM, four 10-bit PWM outputs, a 10-bit ADC with computation, a 5-bit DAC, two comparators, a Complementary Waveform Generator (CWG), and communication interfaces including two EUSART, SPI, and I2C. The device operates from 2.3V to 5.5V across an industrial temperature range of -40C to +85C, making it suitable for both battery-powered and industrial applications.
The PIC16F15355-I/MV uses Microchip's enhanced mid-range core with a 49-instruction set and 16-level hardware stack. Core Independent Peripherals such as the CWG, NCO (Numerically Controlled Oscillator), and configurable logic cells allow complex timing and signal generation without CPU intervention, enabling deterministic low-latency responses in motor control and lighting applications.
Typical applications include low-power IoT sensor nodes, LED lighting control, consumer appliances, battery-powered instruments, and industrial control modules. The XLP technology supports sleep currents below 1 uA with multiple low-power modes (Sleep, Doze, Idle), allowing years of operation on a single coin cell. The CWG and 10-bit PWM are well-suited for driving power MOSFETs in synchronous buck or half-bridge converters.
When designing with this device, allocate pin functions early because some peripherals share I/O pins. Use the MPLAB X IDE with MPLAB Code Configurator (MCC) for rapid peripheral setup, and verify the 32MHz internal oscillator accuracy against timing-critical requirements such as UART baud-rate generation.

Typical Applications
PIC16F15355-I/MV is suitable for 6 applications: Battery-Powered IoT Sensor Node, LED Lighting and Dimming Control, Consumer Appliance Control, Industrial Sensor Transmitter, HVAC Fan and Blower Controller, Portable Medical Monitoring Device.
Battery-Powered IoT Sensor Node
The PIC16F15355-I/MV is well suited for battery-powered IoT sensor nodes because its eXtreme Low-Power (XLP) technology delivers sleep currents below 1 uA with full RAM retention and wake-on-interrupt capability. The 10-bit ADC with computation performs automated averaging and threshold comparison in hardware, offloading the CPU and allowing the device to wake, sample, transmit via EUSART or I2C, and return to sleep within milliseconds. At typical duty cycles of 0.1%, the MCU averages under 10 uA total current, extending coin-cell battery life to several years. The 14 KB Flash comfortably supports BLE command stacks, sensor compensation routines, and OTA bootloader code for field-upgradable sensor deployments.
Recommended
LED Lighting and Dimming Control
The PIC16F15355-I/MV's four 10-bit PWM channels and Complementary Waveform Generator (CWG) make it a strong fit for multi-channel LED drivers and dimming controllers. The CWG generates complementary MOSFET gate-drive signals with programmable dead time for synchronous buck or half-bridge topologies driving high-brightness LED strings. Hardware-based PWM operates independently of the CPU, eliminating flicker even when the core executes user-interface code. The 5-bit DAC combined with two comparators enables closed-loop current regulation for constant-current LED strings, while the small 4x4 mm UQFN footprint supports space-constrained downlight and bulb form factors. The wide 2.3V-5.5V supply range accommodates both battery-powered decorative lighting and 5V mains-referenced designs.
Recommended
Consumer Appliance Control
In consumer appliances such as coffee makers, blenders, and small kitchen tools, the PIC16F15355-I/MV provides deterministic real-time control via its enhanced mid-range core and Core Independent Peripherals. The CWG drives motor or heater switching with no CPU latency, while the 10-bit ADC reads temperature, weight, or humidity sensors for closed-loop control. Two EUSART ports enable simultaneous communication with a user-interface display and a main controller. With 14 KB Flash and 256 B EEPROM, the device stores user presets, calibration data, and fault logs reliably across power cycles. The industrial temperature grade and surface-mount UQFN package suit the high-vibration, high-temperature environment inside appliance enclosures.
Recommended
Industrial Sensor Transmitter
The PIC16F15355-I/MV is well suited for 4-20 mA loop-powered or RS-485 industrial sensor transmitters because of its low sleep current, hardware comparators for signal conditioning, and integrated 10-bit ADC with computation. The two on-chip comparators handle threshold detection and over-range protection without external op-amps, while the ADC's hardware accumulator averages 32 samples automatically for noise rejection on 4-20 mA loops. The dual EUSART ports support RS-485 half-duplex with auto-direction control and an isolated debug UART. Industrial -40C to +85C operation and a small 4x4 mm UQFN footprint enable compact DIN-rail or field-mount transmitter designs where PCB real estate is at a premium.
Recommended
HVAC Fan and Blower Controller
The PIC16F15355-I/MV drives variable-speed fans and blowers in HVAC equipment by combining its Complementary Waveform Generator with four 10-bit PWM channels. The CWG produces dead-time-adjusted complementary outputs for direct BLDC or PFC-stage gate drive, while the 10-bit ADC reads tachometer, current, and temperature feedback for closed-loop speed control. The 32 MHz core executes PI control loops with 31.25 ns instruction cycle, supporting sub-millisecond update rates. Hardware CIPs offload PWM fault handling and overcurrent protection, allowing the CPU to manage communication and user interface. Industrial temperature grade and small UQFN-28 footprint support embedded blower modules with strict space constraints.
Recommended
Portable Medical Monitoring Device
The PIC16F15355-I/MV fits portable medical monitoring peripherals such as pulse oximeters, digital thermometers, and pill reminders because of its XLP low-power operation, deterministic real-time response, and integrated analog peripherals. The 10-bit ADC with hardware computation averages photodiode or thermistor readings automatically, reducing CPU load and measurement latency. Two comparators implement window detection for alarm thresholds, waking the CPU only when readings cross limits. Below 1 uA sleep current extends battery life in continuous-wear devices, and the small 4x4 mm UQFN package fits wrist-worn form factors. Note that this part is not FDA-cleared; finished medical devices still require full regulatory qualification at the system level.

- eXtreme Low-Power technology (vs PIC18F4550-I/P)
Design Notes
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin, and a bulk 1-10 uF capacitor on the supply rail. The PIC16F15355-I/MV draws up to ~3 mA active at 32 MHz and below 1 uA in Sleep, so a clean VDD is critical to avoid ADC noise. Place a ferrite bead or small inductor in series with the analog supply if ADC accuracy is degraded by digital switching noise on shared rails.
Estimated: the 28-pin UQFN package has a typical theta_JA of approximately 40-50 C/W on a standard 4-layer JEDEC test board. At the maximum supply current of ~3 mA active and 5.5 V supply, dissipation is below 17 mW, so self-heating is negligible. However, soldering the exposed thermal pad (EP) to a grounded copper pour is still required for mechanical reliability and to meet IPC-2221 creepage guidelines.
Use the manufacturer's UQFN-28 land pattern from the package drawing; the exposed pad must be soldered to a copper area of at least 2x2 mm to avoid lifted packages during thermal cycling. Place ICSP programming pins (ICSPCLK on RB6, ICSPDAT on RB7) so they remain accessible for in-circuit programming without removing the board from its enclosure. Keep clock traces short and route the internal 32 MHz HFINTOSC node away from analog input traces.
Do not assume the 32 MHz internal oscillator is accurate enough for UART communication without calibration; perform OSCTUNE trimming at production to achieve +/-1% frequency error, or use an external 16 MHz crystal with the PLL for high-speed EUSART. MCLR must be tied to VDD through a 10 kohm pull-up for normal operation; leaving it floating causes random resets. When using the CWG, ensure dead-time is set higher than the MOSFET turn-off time to prevent shoot-through.
