PIC24F16KA304-I/MV Visão geral
What is a PIC microcontroller? A PIC (Peripheral Interface Controller) microcontroller is a compact, programmable integrated circuit that combines a CPU, memory, and peripherals on a single chip. PIC24F devices belong to the 16-bit MCU family within Microchip's broader taxonomy: MCU -> 16-bit microcontroller -> PIC24F -> PIC24F KA family. The XLP series targets battery-powered and energy-harvesting applications where nanoamp sleep currents extend operating life across multi-year deployments.
Key features of the PIC24F16KA304-I/MV include DSBOR (Deep Sleep Brown-Out Reset), DSWDT (Deep Sleep Watchdog Timer), and RTCC (Real-Time Clock/Calendar) that continue running in Deep Sleep mode. The 16 MIPS performance, 12-bit ADC with CTMU for capacitive touch sensing, and 5.5K x 24 Flash organization make this device well-suited for general-purpose embedded control with ultra-low standby power requirements.
The PIC24F16KA304 utilizes a modified Harvard architecture with 16-bit instructions and 24-bit wide Flash words. The XLP technology delivers nanoWatt sleep currents and Deep Sleep modes that preserve peripheral state while minimizing energy consumption for battery-constrained designs.
Typical applications include battery-powered sensor nodes, wearable health monitors, remote controls, IoT edge devices, capacitive touch user interfaces, and energy-harvesting systems. The CTMU peripheral enables cost-effective mTouch capacitive touch buttons and sliders without external analog components.
When designing with this device, prioritize power profile analysis using Microchip's MPLAB X IDE with XLP Energy Explorer. Decoupling capacitors should be placed adjacent to VDD/VCAP pins, and unused I/O pins must be configured as outputs to minimize sleep current leakage.

Aplicações típicas
PIC24F16KA304-I/MV é adequado para 6 aplicaçãos: Battery-Powered IoT Sensor Node, Wearable Health Monitor, Capacitive Touch User Interface, Remote Control / Wireless Sensor, Energy Harvesting Sensor, Industrial Sensor / HVAC Controller.
Battery-Powered IoT Sensor Node
The PIC24F16KA304-I/MV is engineered for battery-powered IoT sensor nodes requiring multi-year battery life. The XLP technology delivers nanoamp Deep Sleep currents (<100 nA typical with RTCC active), while the 32MHz/16 MIPS core provides headroom for protocol stacks like BLE, LoRa, or Zigbee. The 16KB Flash accommodates full Zigbee 3.0 or LoRaWAN stacks with application firmware. With 1.8V to 3.6V operation, the device runs directly from a single CR2032 coin cell or two AA alkaline cells without boost converters. The 12-bit ADC reads sensors at low duty cycle, and the RTCC with Deep Sleep wakes the MCU at scheduled intervals for sub-100uA average current draw. The DSBOR (Deep Sleep Brown-Out Reset) protects data integrity during battery end-of-life events, while DSWDT maintains watchdog operation in Deep Sleep.
Recomendado
Wearable Health Monitor
The PIC24F16KA304-I/MV fits wearable health monitors where size, weight, and battery life are critical. The 6x6mm UQFN-48 package occupies minimal PCB area for compact wrist or patch form factors. The 16KB Flash accommodates biosignal algorithms including ECG QRS detection, SpO2 trending, and pedometer step counting. The CTMU (Charge Time Measurement Unit) enables capacitive touch input for waterproof user interfaces without mechanical buttons. Deep Sleep currents under 100nA extend battery life beyond 30 days on a single 50mAh Li-Po cell. The 12-bit ADC at 100ksps samples heart-rate, temperature, and galvanic-skin-response sensors. The RTCC with alarm wakes the MCU precisely for scheduled measurements, while the 17 I/O pins drive display, haptic feedback, and BLE radio control logic.
Recomendado
Capacitive Touch User Interface
The PIC24F16KA304-I/MV with integrated CTMU peripheral drives capacitive touch buttons, sliders, and proximity sensors without external analog components. The CTMU generates precise current pulses measured by the 12-bit ADC to detect capacitance changes from finger proximity. With 17 available I/O pins, the device supports up to 16 touch electrodes plus one LED driver or buzzer output. The 16 MIPS performance enables real-time touch scanning at 100Hz with sub-2ms response time for snappy UI feel. XLP Deep Sleep lowers standby current below 1uA when no touch activity occurs, extending battery life in remote controls, white-goods panels, and industrial HMIs. The 16KB Flash stores touch-tuning parameters and gesture recognition firmware for advanced interfaces.
Recomendado
Remote Control / Wireless Sensor
The PIC24F16KA304-I/MV serves as the controller core in RF remote controls, garage door openers, and wireless sensor transmitters where a coin-cell battery must last 5+ years. The XLP technology with Deep Sleep current below 100nA allows the MCU to sleep most of the time and wake only when a button is pressed. With 16KB Flash, the device stores rolling-code encryption firmware for secure wireless protocols. The 17 I/O pins support up to 16 keys plus an LED, and the RTCC with Deep Sleep schedules periodic wake-up for sensor readings in security/environmental sensors. The 1.8V minimum VDD operation runs directly from a single CR2032 without boost converter overhead.
Recomendado
Energy Harvesting Sensor
The PIC24F16KA304-I/MV's nanoWatt XLP performance makes it ideal for energy-harvesting applications where ambient energy (solar, thermal, vibration) provides sub-milliwatt power budgets. The Deep Sleep current below 100nA means the device spends >99.9% of time sleeping and only processes when sufficient energy accumulates in storage capacitors. The DSBOR prevents spurious operation during brown-out conditions, while the RTCC maintains accurate timekeeping during sleep with negligible current draw. The 12-bit ADC reads harvestable voltage on a periodic basis, allowing maximum power point tracking with the MCU's compute headroom. The 32MHz core executes energy-management firmware in milliseconds, then returns to Deep Sleep.
Recomendado
Industrial Sensor / HVAC Controller
The PIC24F16KA304-I/MV handles industrial sensor and HVAC controller applications requiring reliable operation in electrically noisy environments. The 1.8V to 3.6V operation with built-in brown-out reset protects against industrial supply transients. The 12-bit ADC reads multiple 0-10V or 4-20mA sensor inputs via external signal conditioning. With 16KB Flash, the device implements PID control loops, Modbus RTU protocol, and user-interface firmware. The 17 I/O pins drive relay outputs, triac controls, and communication interfaces. The RTCC provides time-of-day scheduling for HVAC setback control and industrial process timing. The CTMU enables sealed front-panel touch controls without mechanical buttons that could fail in industrial environments.

Notas de projeto
The PIC24F16KA304-I/MV XLP technology achieves Deep Sleep currents below 100nA with RTCC active. To minimize sleep current: configure all unused I/O pins as digital outputs driving low, disable unused peripherals via PMDx registers, and disable the ADC by setting AD1CON1bits.ADON=0 before entering Sleep. Use the DSBOR with appropriate trip voltage setting for the VDD range. The VCAP pin requires a 10uF ceramic decoupling capacitor placed within 1cm of the pin for internal voltage regulator stability.
For the 48-UQFN (MV) package, route the central thermal pad to VSS using multiple vias in a 3x3 array pattern for proper thermal and electrical grounding. Place the 10uF VCAP capacitor adjacent to pin 28 with trace length under 5mm. Decouple each VDD/VSS pair with a 100nF ceramic capacitor, and add a 1uF bulk capacitor near the package power entry point. Maintain 50-ohm impedance on clock traces (OSC1/OSC2) if using an external oscillator.
Critical pitfall: the MCLR pin (pin 7) requires a 10k pull-up to VDD; leaving it floating results in random resets. The CTMU peripheral requires calibration - skip the CTMU calibration sequence at reset or touch sensitivity will be unreliable. When migrating code between KA302 and KA304 variants, update the linker script to map 16KB Flash regions; an 8KB linker script will silently truncate code. The VCAP pin must NEVER be left floating - the device will not operate without the regulator output capacitor.
