부품 번호: PIC24F16KA301-E/SO ✓ 활성PIC24F16KA301-E/SO 개요
PIC24F16KA301 devices belong to the PIC24F general-purpose Flash microcontroller family and combine a 16-bit RISC core with low-power operating features. The PIC24F16KA301 family includes DSBOR, DSWDT, and RTCC functions that continue operating in Deep Sleep mode, helping preserve system functionality while reducing current consumption in applications that spend substantial time between active processing periods. The MCU is suitable when a design needs more control and peripheral capability than an 8-bit controller while retaining a compact, straightforward embedded architecture.
The device provides 16 KB of Flash memory organized as 5.5K x 24 words, 2 KB of RAM, and 512 bytes of EEPROM. Its 12-bit ADC supports analog measurement, while CTMU provides capacitive-measurement support for touch-style sensing and other analog front-end functions. An internal oscillator is listed for the device, helping reduce external clock-component requirements in cost-sensitive embedded products.
Typical applications include battery-operated sensors, compact consumer controls, industrial monitoring equipment, portable instruments, low-power sensor nodes, and embedded products that need a dedicated 16-bit controller. The 20-SOIC package is useful when a through-hole-compatible assembly process is preferred while still using surface-mount technology. Designers should confirm the exact pin functions, peripheral multiplexing, and electrical limits in the manufacturer datasheet before assigning board functions.
Choose the PIC24F16KA301-E/SO when the design requires a 16-bit PIC core, 32 MHz operation, 16 KB Flash, low-power Deep Sleep support, and an extended-temperature 20-pin SOIC option. For a pin-compatible migration, the -I/SO grade changes the temperature class and should be selected only when its specified operating range and qualification requirements suit the product. This page combines manufacturer specifications, lifecycle context, drop-in alternatives, application guidance, and PCB-level design notes for faster component evaluation.

일반적인 애플리케이션
PIC24F16KA301-E/SO 적합 용도: 6 애플리케이션s: Battery-Powered Sensor Node, Portable Medical Monitoring, Industrial Condition Monitoring, Capacitive-Touch User Interface, Low-Power Data Logger, Battery-Powered Consumer Appliance.
Battery-Powered Sensor Node
PIC24F16KA301-E/SO fits battery-powered sensing products because its 16-bit PIC24F core provides 16 MIPS at up to 32 MHz while XLP features support low-duty-cycle operation. DSBOR, DSWDT, and RTCC can remain active during Deep Sleep, reducing the risk of losing timing, watchdog, or clock functions when the main processor sleeps. The 12-bit ADC supports direct sensor conditioning, while CTMU enables capacitive sensing without requiring a dedicated controller. A practical design keeps the MCU powered during periodic measurements, places it into Deep Sleep between readings, and sizes the battery around the combined MCU and sensor sleep currents.

Portable Medical Monitoring
PIC24F16KA301-E/SO is suitable for compact monitoring instruments that combine low-power operation with analog measurement. The 12-bit ADC can process sensor outputs, CTMU supports capacitive electrode measurements, and the 16-bit RISC architecture provides more arithmetic headroom than an 8-bit MCU. The -E/SO grade is listed for operation from -40C to 125C, making it useful across equipment intended for varying ambient conditions. In a portable design, the MCU can sleep between sample cycles while DSWDT preserves independent supervision and RTCC maintains a real-time reference. Power-system design should verify sensor excitation, isolation, and regulatory requirements independently of the MCU selection.

Industrial Condition Monitoring
PIC24F16KA301-E/SO can serve as the local controller in an industrial monitoring node that measures analog sensor signals and records state during intermittent operating periods. Its 32 MHz maximum frequency and 16 MIPS throughput allow control-loop and communication tasks to share one processor, while the 18 I/O pins support digital status inputs and external interfaces. The extended-temperature grade covers -40C to 125C ambient operation, although the final enclosure, regulator, and sensor ratings must also satisfy the system requirements. Use the internal oscillator listed for this device where its timing tolerance is adequate, and review clock accuracy and EMC performance before committing to a production layout.

Capacitive-Touch User Interface
PIC24F16KA301-E/SO is appropriate for small capacitive-touch controls because CTMU provides the analog measurement function alongside a 12-bit ADC and a 16-bit processing core. A low-power front panel can scan electrodes, apply thresholding and debounce logic, then enter Deep Sleep while waiting for another user action. The 20-pin SOIC package keeps the controller compact while retaining enough I/O for LEDs, buttons, and an interface to a host processor. CTMU timing, acquisition time, and electrode compensation should be configured with the external network values specified by Microchip Technology, while conducted and radiated immunity testing remains necessary for a production touch interface.

Low-Power Data Logger
PIC24F16KA301-E/SO suits a portable data logger that samples sensors periodically and retains information in a compact 16-bit Flash MCU. The 16 KB program memory supports the application and bootloader, while 512 bytes of EEPROM can hold configuration or calibration values. XLP operation and the availability of DSBOR, DSWDT, and RTCC during Deep Sleep help preserve critical timing functions between acquisition sessions. The internal oscillator can simplify the BOM, but its accuracy should be checked against the required time stamps. If records are stored externally, a serial interface can be added through an I/O expander without changing the MCU package.

Battery-Powered Consumer Appliance
PIC24F16KA301-E/SO can control compact battery-powered consumer products where standby power is as important as active processing performance. The 32 MHz core handles display updates, button logic, and actuator control, while Deep Sleep reduces consumption when the product is idle. The 12-bit ADC can monitor a battery or analog control point, and CTMU can support touch or slider input. Tube packaging and the 20-pin SOIC outline support conventional surface-mount assembly. Designers should use the MCU's low-power states together with load switches and an efficient regulator, then calculate the runtime from measured sleep and active currents rather than from peak current alone.

설계 노트
Design the power tree around the MCU's active and Deep Sleep states. The PIC24F16KA301-E/SO can retain DSBOR, DSWDT, and RTCC functions during Deep Sleep, allowing the processor to sleep without losing selected supervisory or timing functions. Select a regulator whose quiescent current and dropout behavior suit the battery, and calculate runtime from measured active and sleep currents. Wake sources should be configured so that unused peripherals do not prevent the lowest acceptable sleep current.
Follow the Microchip Technology 20-pin SOIC footprint and pin-description table for every pad, programming interface, supply connection, and analog input. Place the decoupling network at the device supply pins with a short return path to the ground plane. Separate sensitive analog routing from fast digital or CTMU paths where practical, and keep the analog ground connection strategy consistent with the device's pin assignments. Validate clearances against the manufacturing process and the final assembled board.
Treat the 12-bit ADC and CTMU as precision analog peripherals. Use short traces from the MCU pins to the relevant RC networks, maintain a continuous ground reference beneath the analog section, and avoid routing switching-node or high-current paths adjacent to measurement inputs. If CTMU is used for capacitive sensing, follow the application guidance for electrode geometry, acquisition timing, and filtering. These steps reduce conversion errors and sensitivity to PCB leakage and switching noise.
Do not treat identical SOIC packages as proof that every suffix is interchangeable. PIC24F16KA301-E/SO and PIC24F16KA301-I/SO share the 20-pin SOIC footprint, but the temperature-grade and automotive-qualification intent can differ. Confirm the exact grade, operating range, qualification, supply limits, and pin multiplexing in the manufacturer datasheet before releasing a replacement BOM. Also verify the programmed device configuration and boot or programming interface if the original design uses production programming tools.
규정 준수 정보
No explicit compliance declaration for PIC24F16KA301-E/SO was identified. The -I/SO alternative is described as an automotive-grade option in a product listing, but that statement does not establish AEC-Q100 status for the -E/SO target.
