PIC24FV32KA302-E/SP 개요
A 16-bit microcontroller (MCU) is a programmable system-on-chip that combines a 16-bit CPU core, Flash program memory, SRAM data memory, and a rich peripheral set into a single integrated circuit. Within the broader semiconductor taxonomy, the PIC24F family sits between 8-bit PIC MCUs and 32-bit ARM Cortex-M parts, providing a migration path for applications that exceed 8-bit performance but do not require a 32-bit core. The PIC24FV32KA302-E/SP integrates peripherals that continue operating in Deep Sleep mode (DSBOR, DSWDT, RTCC), which is the defining feature of the XLP family.
Key features include 32KB (11K x 24) of self-programmable Flash, 2KB of SRAM, 512 bytes of EEPROM, 17 general-purpose I/O pins, and a 12-bit A/D converter with up to 16 channels. Communication peripherals include UART, SPI, and I2C interfaces, while advanced features include a 5-channel 16-bit timer, capture/compare/PWM modules, a Configurable Logic Cell (CLC), and a CTMU (Charge Time Measurement Unit) for capacitive touch sensing. The device supports 3.3V and 5V operation with nanoWatt XLP power management that achieves sub-uA sleep currents.
The PIC24FV32KA302-E/SP uses a Modified Harvard architecture with a 16-bit data path and 24-bit instruction word, enabling efficient C code execution via the MPLAB XC16 compiler. The integrated 8 MHz internal RC oscillator with PLL provides 32 MHz operation, eliminating the need for external crystals in cost-sensitive applications while maintaining USB-friendly timing accuracy.
Typical applications include battery-powered IoT nodes, portable medical devices, sensor interface modules, capacitive touch user interfaces, and industrial control systems that require extended temperature operation. The wide 2.0V-5.5V range makes the device directly compatible with both 3.3V and 5V system rails.
When designing with this part, populate the ICSP programming header on the PCB even for factory-programmed parts, as firmware revisions may require field updates. The AVDD/AVSS pair should be tied to the main VDD/VSS rails via a ferrite bead or short trace when high ADC accuracy is required. The 'E' temperature grade qualifies the part for -40C to +125C operation, suitable for industrial and outdoor enclosures.

일반적인 애플리케이션
PIC24FV32KA302-E/SP 적합 용도: 6 애플리케이션s: Battery-Powered IoT Sensor Node, Capacitive Touch User Interface, Portable Medical Monitoring Device, Industrial Sensor Interface Module, Smart Meter and Energy Monitoring, Automotive Auxiliary Controller.
Battery-Powered IoT Sensor Node
The PIC24FV32KA302-E/SP is well-suited for battery-powered IoT sensor nodes due to its XLP Deep Sleep current under 1 uA and 2.0V-5.5V wide-voltage operation from a single lithium or 2xAA battery. The 32KB Flash and 2KB RAM support typical sensor-fusion firmware including temperature/humidity/boundary acquisition, BLE driver code, and low-power protocol stacks (LoRaWAN, Zigbee, or proprietary Sub-GHz). The 17 GPIO easily accommodate I2C/SPI sensors, status LEDs, and wake-up interrupt sources. Power dissipation is minimized by entering Deep Sleep between transmissions while RTCC maintains a wake schedule. The 32 MHz core allows on-chip data compression before TX bursts, reducing radio on-time and extending battery life to years.

Capacitive Touch User Interface
The PIC24FV32KA302-E/SP integrates the CTMU peripheral which provides accurate charge-time measurement for capacitive touch sensing on up to 13 channels via the 17 GPIO. The 12-bit ADC enables proximity and slider gesture decoding without an external touch controller, reducing BOM cost. The wide 2.0V-5.5V supply tolerates noisy USB or battery rails common in appliance and consumer products. With 32 KB Flash, designers can host both capacitive-touch firmware and main product logic on a single chip, simplifying layouts in HMI panels, kitchen appliances, and industrial control keypads.

Portable Medical Monitoring Device
Medical wearables and portable monitors benefit from the PIC24FV32KA302-E/SP's extended -40C to +125C temperature grade, XLP nanoWatt power modes, and integrated 12-bit ADC for biosignal acquisition. The 32KB Flash stores small firmware stacks for pulse-oximetry, ECG pre-processing, or thermometry while 2KB RAM buffers sample data. The 5V tolerance protects against transients on body-coupled electrodes and battery chargers. The extended temperature grade supports storage at -40C (clinical refrigerators) and operation during fevers/elevated skin temperatures. CTMU supports touch-free proximity wake-up for clinician interaction.
추천
Industrial Sensor Interface Module
The PIC24FV32KA302-E/SP is qualified for industrial automation with its -40C to +125C extended temperature range and 5V I/O tolerance for legacy sensor interfaces including 4-20 mA loops, 0-10V analog signals, and 24V digital inputs via external clamping. The 17 GPIO accommodate multiple sensor inputs, status LEDs, RS-485 transceivers, and isolated digital I/O. The CLC (Configurable Logic Cell) allows custom glue logic implementation directly on-chip, replacing external gates. Modbus RTU slave firmware fits easily in 32KB Flash, and the internal 8 MHz RC oscillator with PLL eliminates external crystals in cost-sensitive field installations.

Smart Meter and Energy Monitoring
Smart electricity meters and energy monitoring sub-systems leverage the PIC24FV32KA302-E/SP's 12-bit ADC for current/voltage sensing, EEPROM for non-volatile log storage (kWh readings survive power-down), and RTCC for time-of-use billing calculations. The 2.0V-5.5V range allows direct operation from a regulated DC bus or auxiliary supply. CTMQ can detect meter-tamper events via capacitance change, while the XLP Deep Sleep current keeps idle consumption below regulatory thresholds. The extended temperature grade supports -25C outdoor metering in cold climates and +55C inside distribution enclosures.
추천
Automotive Auxiliary Controller
Body-of-system and aftermarket automotive electronics, including lighting controllers, HVAC panels, and seat-control units, can use the PIC24FV32KA302-E/SP for 5V-tolerant I/O interfacing with legacy 12V automotive rails via external transients/ESD protection. The -40C to +125C grade covers under-hood and cabin extremes from cold-start to summer sun exposure. CTMU supports touch-sensitive control surfaces, and the CLC implements custom logic without external gates. Note: This 'E' grade is industrial-extended, not full automotive-grade (AEC-Q100); for AEC-Q100, use the PIC24F32KA302-E/SP-Q variant or Microchip automotive PIC series.

설계 노트
The XLP Deep Sleep current can drop below 1 uA when properly configured: disable all unused peripherals via PMD registers, set all unused GPIO as outputs driving low, and use RTCC alarm to wake. Estimated: at 3.3V with everything off and only RTCC active, expect ~800 nA. Use the datasheet Figure 31-15 ('Deep Sleep Current vs. Temperature') to verify against temperature extremes, since leakage rises at +85C and above.
Place a 100 nF decoupling capacitor within 3 mm of each VDD pin (pins 13 and 28 of the SPDIP-28), and a bulk 10 uF tantalum or ceramic cap on the same supply rail. The AVDD/AVSS pair (or shared VDD/VSS in this part) should be tied directly without ferrite beads for general applications; insert a ferrite only when ADC noise exceeds 1 LSB. ICSP header (RB6/RB7) should be brought out to a 6-pin header for in-circuit programming and debugging, even on factory-programmed parts.
Do not confuse the PIC24FV (wide voltage 2.0V-5.5V) with the PIC24F (1.8V-3.6V only); using the wrong variant at 5V will damage the part. The 'E' suffix indicates -40C to +125C extended grade; do not substitute with 'I' grade (-40C to +85C) for outdoor or industrial deployments. Pin 24 (MCLR/VPP) must be tied to VDD via a 10 kΩ pull-up for normal operation; leaving it floating prevents code execution. The configuration bits must be set correctly for the internal oscillator and PGx pins; defaults may not match your schematic.
규정 준수 정보
RoHS and lead-free compliant per Microchip product page. 'E' grade is extended industrial (-40C to +125C), not AEC-Q100 automotive qualified. For AEC-Q100, use the Microchip automotive PIC24 family variants.
