MPN: PIC24F16KA302-E/SS ✓ פעילPIC24F16KA302-E/SS סקירה
A 16-bit microcontroller is a programmable integrated circuit that processes instructions and data on a 16-bit-wide datapath, sitting in the hierarchy between 8-bit MCUs (lower cost, lower performance) and 32-bit MCUs (higher performance, higher cost). 16-bit PIC24F parts occupy the sweet spot for embedded designs that need more computational headroom than 8-bit can offer, while keeping power and code density low. The PIC24F16KA302 belongs to the broader PIC24F family of flash microcontrollers, which itself sits under Microchip's microcontroller IC product line within power management and embedded control semiconductors.
Key differentiating features include the XLP technology platform with nanoWatt XLP sleep modes, on-chip 12-bit ADC with CTMU (Charge Time Measurement Unit) for capacitive touch and precise time measurement, and unique peripherals like DSBOR (Deep Sleep Brown-Out Reset), DSWDT (Deep Sleep Watchdog Timer), and RTCC (Real-Time Clock Calendar) that continue to operate in deep sleep. The device supports 1.8V to 1.95V single-supply operation, with active current under 1 mA at full MIPS and deep-sleep currents below 100 nA typical. Multiple communication peripherals including UART, SPI, I2C, and 10-bit ADC channels provide flexible interfacing.
Typical applications include battery-operated sensor nodes, wearable health monitors, IoT edge devices, remote controls, energy harvesting systems, and any portable product where years of battery life are required. The CTMU enables cost-effective capacitive touch buttons and sliders without external components.
Design consideration: select a package variant matching your I/O and thermal budget; the 28-SSOP offers 18 general-purpose I/O with small board area. For systems requiring code execution from external memory or graphics, consider the higher-end PIC24EP or PIC32 families instead.

יישומים טיפוסיים
PIC24F16KA302-E/SS מתאים עבור 6 יישוםs: Battery-Powered IoT Sensor Nodes, Wearable Health Monitors, Capacitive Touch User Interfaces, Remote Controls and RF Key Fobs, Energy Harvesting Wireless Sensors, Industrial Sensor Transmitters.
Battery-Powered IoT Sensor Nodes
The PIC24F16KA302-E/SS is purpose-built for battery-driven edge sensor and IoT nodes where the required under-sub-100 nA nanoWatt XLP deep-sleep current extends coin-cell battery life from months into years. Its 16 MIPS of 16-bit processing handles sensor fusion, RF co-processor control, and over-the-air protocol stack execution while still allowing the device to spend >99% of its time in deep sleep. The CTMU and 12-bit ADC integrate directly with environmental sensors (temperature, humidity, light), and DSBOR/DSWDT/RTCC keep time and supervision alive while the main core is asleep - eliminating the need for an external RTC or supervisor IC.
מומלץ
Wearable Health Monitors
The PIC24F16KA302-E/SS fits wearable health monitoring designs where its extended temperature grade (E suffix, -40C to +125C) survives body-heat and environmental stress. The CTMU enables capacitive touch buttons and sliders for user interfaces on the wearable without external components, reducing BOM and PCB area. Low active current under 1 mA at full MIPS, combined with nanoWatt sleep below 100 nA, supports step counting, heart-rate monitoring, and BLE coordination on a single coin cell for weeks. The 28-SSOP package is thin enough to fit inside slim wearable enclosures while exposing 18 I/O for sensor and display integration.
מומלץ
Capacitive Touch User Interfaces
The PIC24F16KA302-E/SS integrates the CTMU (Charge Time Measurement Unit) to deliver capacitive touch sensing with 12-bit resolution directly on-chip - reducing BOM and PCB area by eliminating external touch controller ICs. Designers can implement buttons, wheels, sliders, and proximity sensors with software-only configuration via MPLAB Code Configurator, achieving sub-100 nA deep-sleep touch wake-up. The 18 I/O pins accommodate up to 12 touch channels with adequate spacing for adjacent-button rejection, making this part a natural fit for appliance controls, remote-control touch panels, and consumer interface replacements of mechanical switches.
מומלץ
Remote Controls and RF Key Fobs
The PIC24F16KA302-E/SS powers RF remote controls and key fobs where button-press wake from sub-100 nA sleep must happen in microseconds. The nanoWatt XLP sleep with CTMU wake-on-touch enables coin-cell battery life exceeding 5 years in typical key fob usage patterns. Its UART/SPI interfaces connect to sub-GHz or 2.4 GHz transmitters (CC1101, nRF24L01+), while 16 MIPS handles rolling-code encryption. The 28-SSOP package is footprint-compatible with automotive interior-space-constrained fobs. Temperature-grade E (-40C to +125C) ensures operation in parked-car summer heat and winter cold.
מומלץ
Energy Harvesting Wireless Sensors
The PIC24F16KA302-E/SS's sub-100 nA deep-sleep current makes it uniquely suited for energy-harvesting wireless sensor nodes powered by solar, thermal, or vibration harvesters. The DSBOR, DSWDT, and RTCC continue running in deep sleep, enabling true energy-neutral operation where the part wakes only when harvest storage has accumulated sufficient charge. The 12-bit ADC reads analog harvest voltages and sensor outputs without waking the core to peak current, and CTMU handles user override buttons. Operating voltage 1.8V to 1.95V is compatible with single-cell supercapacitor storage.
מומלץ
Industrial Sensor Transmitters
The PIC24F16KA302-E/SS supports industrial 4-20 mA loop-powered and battery-backed sensor transmitters where its extended -40C to +125C temperature grade ensures reliable operation in factory floors and outdoor enclosures. The 12-bit ADC reads bridge sensors, RTDs, and 4-20 mA loop signals with 1 LSB precision; the integrated CTMU handles capacitor-based start-up timing for energy harvesting. HART or IO-Link communication stacks fit comfortably in 16 KB Flash. The 28-SSOP package provides mechanical robustness for industrial mounting, and 18 I/O is adequate for multi-sensor transmitters.

הערות תכנון
The PIC24F16KA302-E/SS's nanoWatt XLP deep-sleep current is sub-100 nA typical when configured with DSBOR, DSWDT, and RTCC disabled or properly gated. To minimize sleep current, disable all unused peripherals via PMD bits, switch the system clock to LPRC (31 kHz internal) before sleep, and ensure no floating inputs on I/O pins (configure as outputs or enable internal pull-ups). The 32 MHz HFINTOSC wake time is approximately 2 us; for fast wake scenarios use the PLL in LP mode to reduce wake latency. Estimated active current at 16 MIPS / 32 MHz is approximately 700 uA per MHz, so budget total current draw from active cycles + sleep duty cycle.
Place 100 nF decoupling capacitors as close as possible to each VDD pin of the PIC24F16KA302-E/SS, and add a bulk 10 uF tantalum or ceramic capacitor on the main VDD trace. The 28-SSOP package's exposed thermal pad (if present on this variant) should be soldered to a copper pour connected to VSS for thermal relief. Route the 32 kHz crystal (if used for RTCC) with short traces and guard rings to minimize capacitive loading and noise pickup. CTMU-capable pins must be routed without adjacent switching signals to avoid touch false triggers.
Do not assume the E temperature grade (-40C to +125C) automatically applies to all PIC24F16KA302 - I grade (-40C to +85C) is more widely stocked. Verify voltage scaling mode (LP, FCPU, or HF) before clock configuration - incorrect settings cause Instruction Error or unexpected reset. CTMU requires careful calibration with the on-chip bandgap reference for accurate capacitive touch readings; consult the CTMU library documentation. The MPLAB ICD programmer requires VPP on the MCLR pin during debug; ensure your PCB does not have VPP clamped or limited by capacitance that prevents 9V programming voltage rise time.
For CTMU capacitive touch designs, dedicate PCB touch pad geometry per Microchip application note guidelines - typically 5 mm to 12 mm square pads with at least 1 mm spacing between adjacent buttons, and a ground flood at least 5 mm behind the touch surface. The CTMU converts capacitance to counts via time measurement, so noise on VDD directly impacts touch sensitivity. Route analog signals away from PWM outputs and high-current switching traces to prevent capacitive coupling. Include series resistors (typically 100 ohm) on analog inputs to limit inrush current into the ADC sample-and-hold capacitor.
