PIC24FV16KM102-I/SS Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (typically Flash), working RAM, and a rich set of peripherals such as ADCs, timers, communication interfaces (UART, SPI, I²C), and PWM/capture modules. In the broader system hierarchy, the PIC24FV16KM102 sits between 8-bit PIC MCUs and the higher-end dsPIC/PIC32 families, offering 16-bit data paths and a modified Harvard architecture for deterministic real-time control. It belongs to the power management and embedded control class of ICs, and is used wherever a deterministic, low-power 16-bit MCU is needed.
Key features of the PIC24FV16KM102 include a 12-bit ADC with up to 16 channels (analog-to-digital conversion for sensor interfaces), Configurable Logic Cell (CLC) blocks for hardware glue logic without external gates, multiple Capture/Compare/PWM modules for motor and timing control, and a peripheral pin select (PPS) system that allows flexible mapping of digital functions to physical pins. The wide 2.0 V–5.5 V supply range combined with XLP technology yields deep-sleep currents well below 1 µA in many sleep modes, extending battery life in energy-harvesting and IoT applications.
Typical applications include low-power IoT sensor nodes running from 3.3 V or 5 V rails, industrial sensor signal-conditioning front ends, low-cost motor control for small BLDC or stepper actuators, consumer products such as remote controls and small appliances, and battery-powered instrumentation such as digital thermometers and portable medical peripherals. The integrated 12-bit ADC and CLC peripherals reduce external component count, lowering BOM cost in space-constrained designs.
When designing with this MCU, plan for an external decoupling network on VDD/VSS (typically 0.1 µF + bulk) and reserve PPS remapping for any custom signal routing. Note that the 'I' suffix denotes the industrial temperature grade of -40 °C to +85 °C, suitable for most non-automotive applications.

Typical Applications
PIC24FV16KM102-I/SS is suitable for 6 applications: Battery-Powered IoT Sensor Node, Industrial Sensor Signal Conditioning, Low-Cost BLDC/Stepper Motor Control, Consumer Remote Control / HMI, Portable Medical Peripherals, Automotive Aftermarket Accessories.
Battery-Powered IoT Sensor Node
The PIC24FV16KM102-I/SS is ideal for battery-powered IoT sensor nodes thanks to its 2.0 V–5.5 V supply range and nanoWatt XLP deep-sleep current under 1 µA. With a single-cell Li-ion or 3.3 V coin cell input, no external regulator is required, reducing BOM cost. Its 12-bit ADC with up to 16 channels handles multiple sensors (temperature, humidity, light) without external muxing. Used as the main MCU, it wakes on CLC-configured GPIO events, samples sensors, transmits via UART-connected radio, and returns to deep sleep — extending battery life to multi-year operation in remote deployments.
Recommended
Industrial Sensor Signal Conditioning
The PIC24FV16KM102-I/SS fits industrial 4–20 mA loop-powered sensor conditioning thanks to its 5.5 V max VDD (compatible with loop compliance) and 12-bit ADC resolution. The wide voltage range allows direct supply from 5 V industrial rails without a regulator. Its Configurable Logic Cell (CLC) implements hardware-level debouncing and zero-crossing detection offloading the CPU. Used with op-amp front-ends, it digitizes analog signals, applies linearization in firmware, and outputs via 4–20 mA or digital interfaces — all within an industrial -40 °C to +85 °C operating window.
Recommended
Low-Cost BLDC/Stepper Motor Control
The PIC24FV16KM102-I/SS provides multi-channel Capture/Compare/PWM modules suitable for low-cost BLDC and stepper motor control in small appliances and fans. Its 32 MHz / 16 MIPS core handles trapezoidal commutation and PID loops at moderate PWM rates. The peripheral pin select (PPS) feature allows flexible assignment of PWM outputs and QEI inputs, simplifying PCB layout. Used with gate drivers such as the MCP8024, it drives 3-phase motors from 3.3 V or 5 V rails with precise speed and torque control within the industrial temperature range.
Recommended
Consumer Remote Control / HMI
The PIC24FV16KM102-I/SS suits consumer remote controls and small HMI panels where 2.0 V–5.5 V operation from a single CR2032 coin cell or 2x AA batteries eliminates a boost converter. Its CLC blocks handle IR carrier generation and decoding in hardware, freeing CPU cycles for button scan and LCD driving. Used in TV remotes or HVAC wall controllers, the device wakes on IR receive or key press, processes the command, transmits back, and returns to deep sleep — achieving multi-year battery life at sub-$2 unit cost in a 28-SSOP surface-mount footprint.
Recommended
Portable Medical Peripherals
The PIC24FV16KM102-I/SS fits portable medical peripherals such as digital thermometers, pulse oximeters, and home spirometers due to its low sleep current, deterministic 16-bit core for medical algorithms, and 12-bit ADC for biosignal acquisition. The wide 2.0 V–5.5 V range allows direct operation from 2x AAA or single Li-ion cells. Its industrial -40 °C to +85 °C range handles home and clinical environments. Used as the main controller, it samples sensor data, runs filtering algorithms in firmware, drives an LCD, and logs measurements to EEPROM.
Recommended
Automotive Aftermarket Accessories
The PIC24FV16KM102-I/SS is used in aftermarket automotive accessories such as interior LED controllers, OBD-II data loggers, and universal garage-door interfaces where industrial -40 °C to +85 °C temperature tolerance is sufficient (non-safety applications). Its 5 V tolerance on most I/O pins and 5.5 V VDD max support direct connection to 12 V automotive rails via resistor dividers and protection. Used with a CAN or LIN transceiver, it communicates with vehicle networks, drives MOSFETs for lighting, and runs user-configurable logic in firmware.

Key Differentiators
- Wide 2.0 V–5.5 V supply supports 3.3 V and 5 V designs with one MCU (vs PIC24F16KM102-I/SS)
- 16 KB Flash / 1 KB RAM is the sweet spot between PIC24FV08KM102 and PIC24FV16KM202 (vs PIC24FV16KM202-I/SS)
- Configurable Logic Cell (CLC) hardware blocks offload simple glue logic (vs PIC24FV16KA302-I/SS)
Design Notes
Estimated: When operating from a 3.3 V supply and using Sleep mode with peripherals disabled, deep-sleep current for the PIC24FV16KM102 is typically below 1 µA per the Microchip datasheet. To achieve this in your design, disable all unused peripherals via PMD registers before entering Sleep, switch the system clock to LPRC (31 kHz internal) rather than leaving FRC running, and tie unused I/O pins to defined logic levels (VSS or VDD) rather than leaving them floating. Brown-out Reset (BOR) and watchdog (WDT) contribute several µA each if enabled in Sleep.
Place the 0.1 µF VDD/VSS decoupling capacitor within 2 mm of the MCU's VDD/VSS pins (pin 16/pin 15 on 28-SSOP) to minimize supply noise during high-speed clock transitions. Add a 4.7–10 µF bulk capacitor near the regulator output. Route the MCLR pull-up (typically 10 kΩ to VDD) and any crystal traces as short as possible, and keep high-frequency switching traces (PWM, UART) away from the analog ADC inputs to avoid digital-noise coupling into the ADC.
Do not assume the PIC24FV16KM102 is a drop-in for the PIC24F16KM102 (the F-variant has 1.8–3.6 V supply only) — both are 28-SSOP but the firmware must be recompiled due to different config bits and FRC calibration values. Always configure the Configuration bits correctly in your code (e.g., FOSC, WDT, BOR, LVP) before programming, or the device may fail to start. For in-circuit serial programming (ICSP), PGEC (pin 13) and PGED (pin 14) must not be driven externally during programming.
Compliance Information
RoHS compliant per Microchip product page. Industrial temperature grade (-40 to +85 °C) only — not AEC-Q100 qualified. Choose PIC24FV16KM102-E/SS extended grade or a dedicated AEC-Q100 part for automotive.
