PIC24F16KM202-I/SS Übersicht
A 16-bit PIC microcontroller is a member of the Microchip PIC24F family built on a modified Harvard RISC architecture. The PIC24F family sits within the broader 8/16/32-bit MCU taxonomy and is positioned as ultra-low-power (XLP) mixed-signal controllers for battery-powered and analog-rich embedded designs. These devices bridge the gap between PIC16/PIC18 8-bit controllers and dsPIC33/PIC32 32-bit controllers, providing deterministic interrupt response, hardware DSP-like multiply, and integrated analog that historically required external components.
Key features include a 32 MHz maximum CPU clock (8 MIPS), 16 KB self-programmable Flash, 2 KB SRAM, 512 B EEPROM, integrated 12-bit ADC with up to 9 channels, 8-bit DAC, two operational amplifiers, two comparators, three CLC modules, and multiple Capture/Compare/PWM (CCP/OC) peripherals. The device supports 1.8V to 3.6V operation (PIC24F variant; PIC24FV variants support 2.0V-5.5V), making it ideal for both 3V and 5V system designs depending on variant selection.
The PIC24F16KM202 uses a 16-bit modified Harvard architecture with hardware multiply/divide, 16 working registers, deterministic interrupt latency, and on-chip debugging via ICSP/ICD. Its XLP current consumption can drop into the nanoamp sleep-current range with proper configuration, supporting years of operation from a single coin cell.
Typical applications include low-power IoT sensor nodes, battery-powered medical monitors, industrial sensor signal conditioning with on-chip op-amps, USB device firmware bridges, and consumer products that demand long standby time. The integrated op-amps, comparators, and CLC allow blocks of analog signal conditioning that would otherwise require external ICs, reducing total system cost.
When designing with this MCU, account for the 1.8V-3.6V VDD range and consider that the PIC24FV variants support 2.0V-5.5V for 5V-native systems. For USB peripherals, add an external voltage regulator since the on-chip LDO is not designed for USB PHY supply.

Typische Anwendungen
PIC24F16KM202-I/SS ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Node, Portable Medical Monitoring Device, Industrial Sensor Signal Conditioning, USB HID Device Firmware, Low-Power Display Controller, Consumer Remote Control with Voice Activation.
Battery-Powered IoT Sensor Node
The PIC24F16KM202-I/SS is well-suited for battery-powered IoT sensor nodes due to its eXtreme Low Power (XLP) technology, which supports nanoamp sleep currents with full RAM retention and the ability to wake on interrupts from timers, comparators, or I/O pins. With 16 KB Flash and 2 KB SRAM, it accommodates BLE/Zigbee protocol stacks or LoRaWAN drivers alongside sensor reading code. The 12-bit ADC with 9 channels handles multiple sensor inputs (temperature, humidity, gas, etc.) without external multiplexer ICs. The integrated op-amps enable on-chip signal conditioning for analog sensors like thermistors or photodiodes, while the CLC modules implement custom glue logic without external gates. Power budget: ~30 nA in deep sleep, ~150 uA/MHz active, enabling years of operation from a CR2032 coin cell.

Portable Medical Monitoring Device
Medical monitoring applications such as blood pressure cuffs, pulse oximeters, and wearable fitness trackers benefit from the PIC24F16KM202-I/SS integrated analog front-end. The two on-chip operational amplifiers drive active filters for ECG, EMG, or pulse signals without external op-amps. The 12-bit ADC with hardware accumulation enables clean acquisition of low-amplitude waveforms, while the 8-bit DAC generates reference voltages or bias signals for sensors. With operating temperature range -40C to +85C (industrial grade), the device tolerates typical consumer medical device environments. Low sleep current and fast wakeup (sub-microsecond from sleep) preserve battery life between measurements. The 23 GPIO pins accommodate TFT displays, button inputs, and sensor interfaces simultaneously.
Empfohlen
Industrial Sensor Signal Conditioning
Industrial 4-20 mA loop-powered sensors, RTD/thermocouple readers, and process control peripherals benefit from the PIC24F16KM202-I/SS combination of on-chip op-amps, comparators, and CLC. The two op-amps configure as instrumentation amplifiers for low-level analog signals, while the comparators handle window detection for alarm thresholds. The CLC modules implement PWM dithering, frequency translation, or edge detection in hardware without CPU intervention. The 16 KB Flash supports IEC 61131-3 or custom protocol stacks, and the 512 B EEPROM stores calibration coefficients non-volatilely. The 32 MHz CPU speed allows 1 ms control loops with headroom for safety checks. The 1.8V-3.6V supply range accommodates 3.3V industrial buses.
Empfohlen
USB HID Device Firmware
The PIC24F16KM202-I/SS is suitable for low-speed USB HID devices such as keyboards, mice, custom input panels, and HID-class interfaces when paired with an external 3.3V LDO and USB PHY (since the MCU lacks native USB). With 16 KB Flash and 2 KB SRAM, it comfortably holds USB HID descriptors, interrupt handlers, and device-specific logic. The 32 MHz CPU handles USB polling at 1 ms intervals without CPU saturation. Multiple PWM channels control LED brightness or haptic feedback. The internal 8 MHz oscillator (with PLL to 32 MHz) eliminates external crystal cost in cost-sensitive HID designs. For full-speed USB, migrate to PIC24F USB variants (PIC24FJ/EP families).
Empfohlen
Low-Power Display Controller
The PIC24F16KM202-I/SS drives character LCDs, small TFT panels, or OLED displays in low-power applications. The 23 GPIO pins provide sufficient I/O for 8-bit/16-bit parallel interfaces or SPI for OLEDs. PWM channels control backlight brightness with smooth dimming, while the CLC modules generate custom waveforms for e-paper or segmented displays. The eXtreme Low Power sleep modes (< 100 nA) allow battery-powered displays to operate for months between charges. The 32 MHz CPU smoothly handles frame buffer updates for small TFT panels without noticeable flicker. The integrated comparators detect touch inputs via resistive touch layers.
Empfohlen
Consumer Remote Control with Voice Activation
Voice-activated remote controls and consumer audio peripherals benefit from the PIC24F16KM202-I/SS integrated op-amps and comparators. The op-amps condition microphone signals for envelope detection or simple voice-activity detection, while the comparators trigger wakeup when voice is detected. The 12-bit ADC samples microphone data for keyword recognition. The 8-bit DAC generates beep tones for user feedback. The CLC modules implement simple voice-band filters in hardware. With 16 KB Flash, the device can run small keyword-spotting algorithms. The XLP sleep currents below 30 nA allow the remote to sit idle for years on a single coin cell.

Wichtigste Unterscheidungsmerkmale
- On-chip op-amps, DAC, and CLCs reduce BOM (vs. PIC24F16KL401-I/SS)
- Same silicon die in extended temp grade (vs. PIC24F16KM202-E/SS)
- XLP technology enables years of battery life (vs. PIC24F16KA301T-I/SS)
Designhinweise
The PIC24F16KM202-I/SS supports multiple XLP sleep modes (Sleep, Deep Sleep, VBAT). For battery life, use the Deep Sleep mode (~30 nA typical with RTC) and only wake via configured interrupts. Configure unused peripherals to disabled state to minimize active current. Use the on-chip 8 MHz HFINTOSC instead of external crystal when power budget is tight, switching to LPRC (~32 kHz) for sleep. Always place a 100 nF decoupling capacitor on each VDD pin and a 10 uF bulk capacitor on the main VDD rail.
Do not exceed 3.6 V on VDD - the PIC24F (not FV) variant is NOT 5V tolerant on I/O pins. If interfacing 5V logic, use level shifters or migrate to PIC24FV variant. Do not enable all peripherals simultaneously without checking the cumulative current draw, which can exceed USB inrush limits during enumeration. Always configure unused pins as outputs (low) or inputs with pull-ups, never floating, to minimize current leakage. The 12-bit ADC accuracy depends on clean VREF; bypass AVDD/AVSS with 100 nF + 10 uF capacitors even when using internal VREF.
For 28-SSOP hand-soldering, use flux and 0.5 mm chisel tip at 320C. Reflow profile should follow JEDEC J-STD-020 with peak temperature 245C for lead-free. Keep analog and digital ground separated initially, joining at a single point near the MCU VSS pin to minimize digital switching noise coupling into ADC readings. Route the ICSP clock/data lines (RB6/RB7) with short traces and add 4.7 kohm pull-ups on PGC/PGD if programming issues occur. Place external crystals (if used) within 5 mm of OSC1/OSC2 pins with grounded guard ring.
