PIC24F16KM102-E/SO Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile working memory (SRAM), EEPROM for data retention, and a rich set of peripherals including ADC, timers, communication interfaces and GPIOs. MCUs sit at the lowest tier of the embedded-computing hierarchy above discrete logic and below microprocessors/M SoCs, and are the foundational building block for nearly every embedded product from sensor nodes to industrial controllers. The PIC24F family specifically targets low-power, mixed-signal applications where XLP (eXtreme Low Power) sleep currents in the nanoampere range are required.
Key features include a 12-bit A/D converter with multiple input channels, multiple Capture/Compare/PWM (MCCP/SCCP) modules for motor or power control, analog comparators, configurable logic cells (CLC), and a wide operating temperature window. The XLP nanoWatt technology delivers sleep currents below typical competing MCUs and supports multiple low-power modes such as Sleep, Idle and Doze.
The architecture pairs a 16-bit modified-Harvard CPU with a hardware multiplier and a 32 kHz to 32 MHz internal oscillator block, simplifying BOM by removing external crystals in cost-sensitive designs. The on-chip 12-bit ADC, op-amps, comparators and CLC blocks allow analog front-ends to be built with very few external components, while the MCCP/SCCP peripherals support PWMs for motor, lighting and SMPS control loops.
Typical applications include industrial sensor nodes, low-power IoT edge devices, portable medical accessories, consumer white goods with motor control, capacitive-touch human-interface panels, and battery-powered metering. The wide 1.8V to 3.6V VDD range (with PIC24FV variants at 2.0V to 5.5V) supports single-cell Li-ion or 2x AA chemistries directly. The 28-SOIC package is friendly to hand-soldering and low-cost 2-layer PCBs.
When designing with this device, plan the GPIO/peripheral mapping early, because the limited 28-pin count forces trade-offs between analog channels, PWM outputs and comms interfaces. Also ensure the configuration bits are programmed correctly to enable the internal oscillator and disable unused peripherals for lowest sleep current.

Typische Anwendungen
PIC24F16KM102-E/SO ist geeignet für 6 Anwendungs: Industrial Sensor Nodes, Battery-Powered IoT Edge Devices, Portable Medical Accessories, Consumer White Goods with Motor Control, Capacitive-Touch Human Interface, Smart Metering and Energy Harvesting.
Industrial Sensor Nodes
The PIC24F16KM102-E/SO is well suited to industrial 4-20 mA loop-powered sensor nodes because its nanoWatt XLP sleep current falls below 100 nA in Deep Sleep mode, allowing multi-year operation on small batteries. The 12-bit ADC with multiple input channels supports direct connection to bridge, thermistor and RTD front-ends without external instrumentation amplifiers, while the integrated analog comparators enable fast over-threshold detection for alarm outputs without waking the CPU. The 32 MHz core is fast enough to run Modbus RTU stacks with margin.

Battery-Powered IoT Edge Devices
Battery-powered IoT edge devices such as BLE beacons, Zigbee sleepy end-devices and LoRaWAN Class A sensors benefit from the PIC24F16KM102-E/SO's nanoWatt XLP technology. Sleep currents in the 20-100 nA range extend coin-cell and AA-pack lifetime to multi-year horizons, while the 32 MHz core provides enough MIPS for short radio-burst processing. The MCCP/SCCP peripherals generate accurate PWM for LED or buzzer indicators, and the 12-bit ADC reads battery voltage for state-of-charge estimation.
Empfohlen
Portable Medical Accessories
Portable medical accessories such as glucose meters, pulse oximeters and electronic thermometers benefit from the PIC24F16KM102-E/SO's low-power operation and integrated analog peripherals. The 12-bit ADC with internal reference supports direct connection to electrochemical test strips and optical photodiode front-ends, while the analog comparators enable fast heart-rate or threshold detection. The -40C to +125C extended temperature grade supports sterilization and ruggedized enclosures.
Empfohlen
Consumer White Goods with Motor Control
Small kitchen and cleaning appliances with brushed DC or BLDC motors can use the PIC24F16KM102-E/SO's MCCP/SCCP peripherals to generate PWM, complementary PWM, and fault-aware motor control. The Configurable Logic Cells (CLC) allow dead-time and brake-logic to be implemented in hardware without consuming MIPS, freeing the CPU for user-interface and sensing tasks. The 28-SOIC package is hand-solderable, simplifying low-volume production.

Capacitive-Touch Human Interface
Capacitive-touch keypads, sliders and proximity sensors can use the PIC24F16KM102-E/SO's 12-bit ADC with the on-chip CVD (Charge Time Measurement Unit) peripherals to detect touch without dedicated touch ICs. The CLC blocks de-bounce and de-noise in hardware, and the nanoWatt XLP sleep current is low enough to keep touch-wake polling affordable on coin-cell power. The 32 MHz core updates 16 touch channels at 100 Hz with margin to spare.
Empfohlen
Smart Metering and Energy Harvesting
Smart electricity meters, gas meters and water meters that trickle-charge from energy harvesters can leverage the PIC24F16KM102-E/SO's nanoWatt XLP technology. The 1.8 V minimum VDD supports direct connection to small solar or vibration harvesters without boost conversion, while the 12-bit ADC reads metrology signals with sufficient resolution for billing-grade accuracy in many jurisdictions. The internal 32 MHz oscillator removes the need for a power-hungry external crystal.

Designhinweise
Use the PIC24F16KM102's nanoWatt XLP Deep Sleep mode for battery applications. Tie both VDD pins (13 and 28) and both VSS pins (12 and 27) to the supply rails to keep the internal bond wires sharing current evenly. Add a 100 nF ceramic decoupling capacitor as close as possible to each VDD pin plus a bulk 1-10 uF tantalum or ceramic cap on the supply rail. Without the bulk cap, sleep-to-active current transients can sag the rail and trigger spurious brown-out resets.
Route MCLR through a 10 kohm pull-up to VDD and a 100 nF cap to ground for a typical soft-start reset. Place the 32.768 kHz crystal (if used) within 5 mm of OSC1/OSC2 with a guard ring tied to ground. Avoid routing high-speed digital traces under the analog ADC input pins to minimize coupled noise; the SOIC-28 package has limited internal ground returns compared to QFN variants.
Do not exceed 3.6 V on VDD - this is the 'F' variant; the 'FV' part number PIC24FV16KM supports 5 V. Programming the configuration bits incorrectly will leave peripherals disabled; always restore factory config bits when migrating between PIC24F16KM102 and PIC24F16KM202. The CLC peripheral must be configured before its outputs are routed to physical pins or the GPIO will float.
Compliance-Informationen
RoHS and REACH compliant per Microchip product page and DigiKey listing. -9V variant is not AEC-Q100 qualified; for automotive designs use PIC24F16KM102-E/SO with appropriate system-level qualification.
