PIC24FV32KA302T-I/SS - 32KB Flash 16MIPS XLP MCU | Microchip
MPN: PIC24FV32KA302T-I/SS ✓ פעילPIC24FV32KA302T-I/SS סקירה
A 16-bit microcontroller (MCU) is a microprocessor that processes data 16 bits at a time, sitting between 8-bit MCUs (lower cost, lower performance) and 32-bit MCUs (higher performance, higher cost). 16-bit devices like the PIC24F family are widely used in motor control, sensor interfacing, and consumer products where 8-bit performance is insufficient but 32-bit cost is unjustified. The 'PIC24F' prefix denotes Flash-based 16-bit cores; the 'V' suffix denotes the wide-voltage variant supporting 5 V operation.
Key features of the PIC24FV32KA302 include 16 MIPS performance from a 32 MHz internal oscillator, peripherals like Real-Time Clock & Calendar (RTCC), Deep Sleep Brown-Out Reset (DSBOR), and Deep Sleep Watchdog Timer (DSWDT) that operate in Deep Sleep mode. The device integrates a 12-bit ADC with up to 13 channels, a Charge Time Measurement Unit (CTMU) for capacitive touch sensing, multiple UART/SPI/I2C interfaces, and 5 PWM channels.
The architecture combines a modified Harvard RISC core with a 17-bit x 17-bit hardware multiplier for DSP-class operations, achieving 16 MIPS throughput while consuming as little as 20 nA in Deep Sleep mode. CTMU enables capacitive touch and basic time-of-flight measurement without an external ASIC.
Typical applications include IoT sensor nodes, battery-powered wearables, capacitive touch user interfaces, low-power medical monitors, and home automation controllers. The wide 2.0-5.5 V operating range simplifies single-cell Li-ion or 2xAA designs without additional LDO stages.
When designing with this MCU, place a 0.1 uF decoupling capacitor as close as possible to each VDD/VSS pair. The 'T' suffix in the part number indicates tape and reel packaging for high-volume assembly. For deep-sleep current-critical designs, also configure DSBOR and DSWDT in firmware to minimize quiescent draw below 1 uA.

Battery-Powered IoT Sensor Node
The PIC24FV32KA302T-I/SS is ideal for battery-powered IoT sensor nodes because its 20 nA Deep Sleep current with RTCC active allows multi-year battery life from a single CR2032 coin cell. The wide 2.0-5.5 V operating range supports direct connection to 2xAA alkaline or single-cell Li-ion batteries without an external LDO. With 32 KB Flash and 2 KB RAM, it can run a typical sensor stack including ADC sampling, CTMU touch input, and a UART/SPI-attached radio module like the LoRa or sub-GHz transceiver. The integrated 12-bit ADC with 13 channels handles multiple sensor inputs in parallel, reducing BOM cost versus an external ADC.
מומלץ
Capacitive Touch User Interface
The integrated CTMU (Charge Time Measurement Unit) makes the PIC24FV32KA302T-I/SS ideal for capacitive touch user interfaces, supporting buttons, sliders, and proximity sensors without a dedicated touch IC. The CTMU provides a constant current source and hardware timer for sub-nanosecond capacitance measurement resolution, enabling reliable touch detection through 3 mm of glass or plastic overlay. With 13 ADC-muxed pins routable to CTMU and 32 KB Flash available for touch firmware plus base application logic, designers can implement 8-12 touch zones plus communication stacks. The XLP architecture ensures touch wake-up from Deep Sleep draws under 1 uA typical.
מומלץ
Portable Medical Monitoring Device
The PIC24FV32KA302T-I/SS suits portable medical monitoring devices such as pulse oximeters, glucose meters, and wearable health patches because its low-power operation extends battery life while the 12-bit ADC provides accurate biosignal measurement. The CTMU can drive optical sensors for pulse oximetry through finger-tip or wrist-mounted photodiodes. With 5 PWM channels available, it can also drive vibration motors, LED indicators, and display backlights without external driver ICs. The wide operating voltage range (2.0-5.5 V) supports direct battery connection for rechargeable Li-ion or primary lithium chemistries common in medical devices.

Home Automation Sensor Hub
For home automation sensor hubs, the PIC24FV32KA302T-I/SS provides multiple serial interfaces (2x UART, 2x SPI, 2x I2C) to connect to Wi-Fi/BLE modules, environmental sensors, and relay drivers. The 32 KB Flash supports Zigbee or Matter-style protocol stacks with room for application logic, while the 2 KB RAM handles buffering for sensor data aggregation. The 5 PWM channels can directly drive LED indicator strips or small DC fans. Deep Sleep mode with sub-microamp current allows battery-backed operation during AC power loss, maintaining critical sensing functions for hours.
מומלץ
Industrial Sensor Transmitter
The PIC24FV32KA302T-I/SS works well in 4-20 mA industrial sensor transmitters because its 12-bit ADC and wide 2.0-5.5 V operating range tolerate unregulated 24 V industrial supplies via a simple LDO. The CTMU enables capacitance-based level sensing for chemical tank monitoring, while the 2 UARTs support RS-485 transceivers for Modbus RTU communication. The -40C to +85C industrial temperature rating suits factory floor environments. Hardware 17x17 multiplier accelerates DSP operations for signal conditioning on strain gauge, pressure, or flow sensor inputs.

Consumer Wearable Device
Consumer wearables like fitness bands, smartwatches, and hearable devices benefit from the PIC24FV32KA302T-I/SS XLP features that enable weeks-long battery life in always-on sensing scenarios. The 32 KB Flash stores BLE stack, activity recognition algorithms, and display drivers for small OLED or segment LCDs driven via PWM or I2C. The CTMU supports touch-sensitive side buttons or gesture control. With peripheral pin select (PPS) remapping available on PIC24F, designers can route peripherals to nearly any pin, simplifying PCB layout for compact wearable form factors.
מומלץ
Smart Meter Data Logger
The PIC24FV32KA302T-I/SS functions as a smart meter data logger thanks to its 512 B EEPROM for non-volatile data retention across power cycles and 32 KB Flash for metering algorithms. The CTMU combined with the 12-bit ADC can measure both electrical parameters (via current transformers) and environmental factors (temperature, humidity). The 32 MHz CPU with hardware multiplier handles real-time tariff calculations and Time-of-Use billing logic. RS-485 or UART connectivity to a concentrator is provided by the integrated UARTs, and the XLP architecture reduces sleep current below 1 uA for battery-backed metering.

הערות תכנון
Estimated: For ultra-low-power designs, configure the PIC24FV32KA302T-I/SS Deep Sleep mode with RTCC, DSBOR, and DSWDT enabled. According to Microchip datasheet, this combination achieves approximately 20 nA quiescent current. Disable unused peripherals via PMD registers before entering Deep Sleep. Wake-up sources should be limited to RTCC alarm, external interrupts, or DSWDT timeout to minimize average current draw in battery-powered IoT applications.
Place a 0.1 uF decoupling capacitor as close as possible to each VDD/VSS pair (pin 9 and pin 10) on the PIC24FV32KA302T-I/SS. Use wide ground traces to provide low-impedance return paths for ADC sampling. For CTMU-based capacitive touch designs, route CTMU-capable pins (RB8/RB9) away from high-frequency switching signals and keep their trace lengths matched. The 28-pin SSOP has a 0.65 mm pitch - use 0.2 mm trace/space minimum for signal routing underneath the package.
Do not exceed 5.5 V on any pin or VDD - the PIC24FV32KA302T-I/SS is a wide-voltage 5 V variant ('FV' suffix) but absolute maximum is 6.5 V. The MCLR pin should be pulled up through a 10 kohm resistor with a 100 nF cap to ground for proper reset behavior. When programming via ICSP, ensure PGC (RB6) and PGD (RB7) lines are not heavily loaded; use 4.7 kohm pull-ups on these lines during in-circuit programming sessions. The 'T' suffix requires reel handling per JEDEC J-STD-033.
For ADC accuracy on the PIC24FV32KA302T-I/SS, route analog signals (RA0-RA5, RB2-RB9) away from digital switching signals like PWM outputs. Use a ground plane split if necessary, joining at a single point near the MCU VSS pin. Add a 10 uF bulk capacitor and an additional 0.1 uF ceramic near the analog supply pin (if used) to filter switching noise. For CTMU touch sensing, surround touch electrodes with a ground hatch to improve noise immunity.
