PIC24F16KA302-E/SO - 16-Bit 32 MHz XLP Microcontroller
MPN: PIC24F16KA302-E/SO ✓ Hoạt độngPIC24F16KA302-E/SO Tóm tắt
A low-power microcontroller is a semiconductor device optimized to complete control tasks while consuming little energy. The PIC24F16KA302 belongs to the PIC24 MCU family and the broader embedded-controller hierarchy. Its low-power design helps equipment remain responsive while reducing energy consumption during idle periods, making the device suitable for portable monitors, industrial sensing nodes, compact controls, and embedded instruments with intermittent operation.
Key specifications include 16 KB of program memory organized as 5.5K x 24 words, 2 KB of RAM, a 32 MHz clock, and 18 I/O pins. The device also integrates a 12-bit ADC and CTMU. Its Deep Sleep architecture supports dedicated low-power functions such as DSBOR, DSWDT, and RTCC operation, allowing selected activities to continue while the main processing path is inactive.
The PIC24F16KA302 combines a 16-bit architecture with dedicated low-power peripherals rather than relying only on software sleep modes. Its flash program memory supports field-updatable firmware, while the 2 KB RAM provides working space for control logic, state retention, and communication buffers. The 12-bit ADC supports analog measurements, and the CTMU can provide capacitive-touch or timing-related measurement functions according to the device configuration and application circuit.
Typical uses include portable environmental sensors, industrial condition-monitoring equipment, battery-powered meters, compact motor-control interfaces, low-power data loggers, and touch-enabled control panels. These applications benefit from the combination of a 32 MHz processing ceiling, 18 I/O pins, analog measurement resources, and the ability to use low-power operating modes between events.
Designers should verify the exact pin functions and exposed peripheral connections in the manufacturer pin-description table before assigning PCB tracks. The -E grade and /SO package designation should be checked against environmental and assembly requirements, while firmware should be validated for wake-up behavior, ADC scaling, and the interaction among DSWDT, DSBOR, and RTCC functions.
This product page combines the manufacturer product information with package, memory, clock, application, and replacement guidance. It also identifies which same-package variants are supported by published cross-reference information and highlights where firmware, qualification, or peripheral differences must be reviewed before substitution.

Ứng dụng tiêu biểu
PIC24F16KA302-E/SO phù hợp cho 6 Áp dụngs: Battery-Powered Environmental Sensor Node, Industrial Condition Monitoring, Portable Medical Monitor, Compact Data Logger, Low-Power Touch Control Panel, Compact Motor or Valve Controller.
Battery-Powered Environmental Sensor Node
The PIC24F16KA302-E/SO fits a battery-powered environmental sensor node because its XLP architecture supports Deep Sleep operation while DSBOR, DSWDT, and RTCC functions remain active. The 12-bit ADC can acquire analog sensor readings, and the 32 MHz processing ceiling handles sampling logic and serial data formatting without requiring a larger processor. With 16 KB of Flash, 2 KB of RAM, and 512 bytes of EEPROM, firmware can support periodic sampling, threshold evaluation, event logging, and configuration retention. Design the wake path to disable unused peripherals and use the RTCC or DSWDT as the timing reference between measurements.
Được đề xuất
Industrial Condition Monitoring
PIC24F16KA302-E/SO is suitable for industrial condition-monitoring modules that combine periodic sensor acquisition with long idle periods. The 18 I/O pins allow connections for digital inputs, status indication, communication interfaces, and discrete sensors, while the 12-bit ADC supports analog condition signals. Its XLP Deep Sleep behavior can reduce power between inspection intervals, and DSWDT provides a low-power timing resource for scheduled wake-ups. For factory equipment, verify the -E temperature grade against the measured internal temperature range and isolate external sensor transients from the controller pins.
Được đề xuất
Portable Medical Monitor
The PIC24F16KA302-E/SO can serve as the control device in a portable medical monitor when its main functions are sensor acquisition, status control, and low-power event handling. The 12-bit ADC supports analog measurement channels, and the 2 KB RAM is suitable for compact filtering and control buffers. XLP operation and Deep Sleep peripherals allow the monitor to reduce consumption between readings or patient events. Because this MPN is not documented here as AEC-Q100 qualified, medical designs should establish their own quality and regulatory requirements rather than assuming automotive-style qualification.

Compact Data Logger
PIC24F16KA302-E/SO fits a compact data logger that must sample intermittently and retain operating parameters. Its 16 KB Flash provides room for control firmware and compact buffers, while 512 bytes of EEPROM can retain calibration or configuration values. The 18 I/O pins support an external memory interface, sensor bus, or write-protect signal, and the 32 MHz clock supports protocol formatting during an active measurement interval. Use Deep Sleep between records, avoid continuous polling of the ADC, and define a safe strategy for write endurance if the logger repeatedly stores changing data in nonvolatile memory.
Được đề xuất
Low-Power Touch Control Panel
The PIC24F16KA302-E/SO is appropriate for a low-power touch control panel because the integrated CTMU supports capacitive measurement functions and the 12-bit ADC can monitor analog controls. Its 18 I/O pins provide interface capacity for display commands, indicator LEDs, and user inputs, while XLP operation allows the panel to sleep between interactions. The 32 MHz processing ceiling supports debouncing and menu logic without adding a high-power processor. Follow the manufacturer CTMU guidance for excitation, sampling timing, and grounding, and ensure the touch electrode network remains compatible with the selected PCB construction.
Được đề xuất
Compact Motor or Valve Controller
PIC24F16KA302-E/SO can control compact motors, valves, and relay-based actuators when the design requires local logic, sensing, and low standby consumption. The 18 I/O pins support digital command inputs, position or limit switches, and actuator drive controls, while the 12-bit ADC can monitor current or position-related analog signals. Its 16-bit architecture and 32 MHz maximum speed support deterministic control calculations during active operation. Drive transistors or relays should absorb inductive switching energy, and firmware should keep the MCU in its low-power state whenever the actuator is idle.

Ghi chú thiết kế
Configure the firmware to enter a low-power state whenever the measurement and communication schedules permit it. Use DSWDT or RTCC to wake the controller rather than leaving the CPU active, and disable unused peripherals and unused ADC channels before idle. Validate wake time, reset behavior, and sensor settling requirements in hardware because a short wake path can consume more energy than a slightly longer active conversion.
Assign PCB signals using the exact 28-pin /SO pin-description table, keeping analog inputs away from switching nodes and high-current return paths. Place input and bulk-decoupling capacitors close to the device power pins, provide a clean return reference for the 12-bit ADC, and route CTMU electrodes away from noisy digital and power circuitry. Verify the 7.62 mm package pitch and assembly orientation against the selected footprint.
Do not treat a related PIC24F16KA301 or KA302 package option as interchangeable solely because it uses a similar package. Compare pin names, analog channel assignments, interrupt behavior, comparator availability, and timer resources against the compiled firmware. Also distinguish the E, I, and T ordering attributes before approving a substitution, since those suffixes can determine temperature range or qualification expectations.
Separate analog sensing paths from actuator drive and communication return currents. If the device controls relays, motors, or valves, use the controller ground as the quiet reference and route high di/dt currents through dedicated power paths. For CTMU measurements, use the manufacturer guidance for excitation and sampling, minimize parasitic capacitance, and test electrode performance with the final enclosure, cable, and human-loading conditions.
Thông tin tuân thủ
The product results describe a lead-free 28-SOIC device for the related industrial ordering option, but no explicit RoHS, REACH, halogen-free, conflict-minerals, or AEC-Q100 declaration is available for the exact MPN. Automotive qualification is therefore not claimed.
