PIC24F16KA301-I/SS - 16-Bit 32MHz Low-Power MCU | Microchip
Référence : PIC24F16KA301-I/SS ✓ ActifPIC24F16KA301-I/SS Présentation
A microcontroller is a programmable integrated circuit containing a processor core, memory, and peripherals on one semiconductor device. The PIC24F16KA301-I/SS belongs to the 16-bit microcontroller hierarchy within embedded processing and general-purpose control. It combines a PIC24 RISC core, Flash program memory, data RAM, EEPROM, communication peripherals, analog conversion resources, and low-power control functions in a compact package intended for embedded system designs.
Key features include 16 KB of Flash memory, 2 KB of RAM, 512 bytes of EEPROM, up to 16 MIPS performance at 3.3 V, a 12-bit ADC, and CTMU peripheral support. The operating supply range is reported as 1.8 V to 3.6 V, allowing use in both low-voltage and 3.3 V systems. The 20-pin SSOP package provides 17 I/O ports according to the retrieved distributor specifications, making the device suitable for compact control boards, sensor nodes, and embedded instruments.
The PIC24F16KA301-I/SS is particularly useful when standby current and wake-up behavior matter as much as processing performance. Its DSBOR, DSWDT, and RTCC features are identified by Microchip as distinctive low-power peripherals, while the 32 MHz clock supports responsive control, communications, and measurement tasks. Engineers can use the 12-bit ADC for analog sensing and CTMU for capacitive or analog measurement functions where the application requires them.
Typical applications include battery-powered sensor nodes, portable measurement instruments, industrial monitoring controllers, compact automation modules, and consumer products with always-on low-power requirements. In a battery-operated design, Deep Sleep can reduce energy consumption during inactive periods, while the PIC24 RISC core handles active-mode control and communication tasks.
Designers should verify the exact pin assignments and peripheral multiplexing in the manufacturer datasheet before PCB layout, especially because the 20-pin SSOP footprint provides limited I/O and exposes fewer signals than larger PIC24F packages. This page consolidates the verified manufacturer, distributor, and cross-reference information while clearly identifying where detailed electrical, timing, or lifecycle data was not available in the supplied records.

Applications typiques
PIC24F16KA301-I/SS convient pour 6 applications: Battery-Powered Sensor Node, Industrial Monitoring Controller, Portable Measurement Instrument, Capacitive Touch Interface, Compact Automation Module, Low-Power Environmental Sensor Hub.
Battery-Powered Sensor Node
The PIC24F16KA301-I/SS fits compact battery-powered sensor nodes because its eXtreme Low Power architecture supports Deep Sleep operation while retaining a 32 MHz PIC24 RISC core for active measurement and control. The 16 KB Flash, 2 KB RAM, and 512-byte EEPROM are sufficient for sensor acquisition logic, configuration storage, and low-duty-cycle communications. Its 1.8 V to 3.6 V supply range supports low-energy sensor rails, although the final regulator, battery chemistry, and sleep current determine achievable runtime. The 20-pin SSOP package also limits board area, so designers should allocate pins carefully for the ADC, communications interface, and wake-up control.
Recommandé
Industrial Monitoring Controller
The PIC24F16KA301-I/SS is appropriate for industrial monitoring controllers that combine periodic sensor reading with low-power standby behavior. Its 12-bit ADC supports analog signal acquisition, while the 32 MHz core provides up to 16 MIPS performance at 3.3 V for local filtering, threshold evaluation, and data formatting. DSBOR, DSWDT, and RTCC can remain active in Deep Sleep according to the Microchip product description, helping preserve state and timing functions without continuous full-power operation. The industrial -I grade is appropriate for industrial environments, but engineers should verify the exact temperature limits and EMC requirements from the manufacturer datasheet.
Recommandé
Portable Measurement Instrument
The PIC24F16KA301-I/SS suits portable instruments where a low-power MCU must operate an ADC and manage controls without a large display or processor. The 12-bit ADC can digitize sensor signals, 2 KB of RAM supports local buffering, and 512 bytes of EEPROM can retain calibration or setup values. Its 1.8 V to 3.6 V operating range enables direct interface to compatible low-voltage analog front ends, subject to input and supply limits. Deep Sleep functionality can reduce consumption between measurements, while the 20-pin SSOP package helps reduce instrument size. Analog grounding and reference design still require careful partitioning around the digital MCU.
Recommandé
Capacitive Touch Interface
The PIC24F16KA301-I/SS can serve as the controller in a compact capacitive-touch interface because the verified Mouser specification identifies CTMU support alongside the 12-bit ADC. CTMU can support capacitance-related measurement functions, allowing touch keys or sensing electrodes to be evaluated without requiring a separate dedicated controller. The 32 MHz core leaves performance headroom for debouncing, filtering, and user-interface updates. A practical design must keep sensing traces and guard structures away from fast digital and switching-current paths, and it must validate scan timing and noise performance across the intended electrode geometry.
Recommandé
Compact Automation Module
The PIC24F16KA301-I/SS is useful in compact automation modules that need local control, status reporting, and analog input handling without a large embedded processor. The 17 I/O ports provide access to digital sensors, indicators, and actuators, while the 12-bit ADC supports process-variable monitoring. Its 16-bit PIC RISC instruction set and 32 MHz operating capability are suitable for responsive control loops and communication tasks. The SSOP package minimizes footprint but offers only 20 pins, so designers should prioritize interfaces carefully and verify pin multiplexing against the official 20-pin package diagram before committing a board layout.
Recommandé
Low-Power Environmental Sensor Hub
The PIC24F16KA301-I/SS fits environmental sensor hubs that periodically sample temperature, light, or gas inputs and communicate the results through a compact serial interface. Its low-power XLP architecture and Deep Sleep support can reduce average consumption during long idle intervals, while the 32 MHz core handles sampling, filtering, and protocol formatting. The 1.8 V to 3.6 V range supports low-voltage sensor platforms, and the 16 KB Flash plus 2 KB RAM provide adequate space for compact embedded firmware. Deployment quality depends on accurate wake timing, sensor standby currents, antenna behavior, and a clean power arrangement that prevents sensor noise from coupling into the ADC.

Notes de conception
Use the verified 1.8 V to 3.6 V operating range as the basis for rail selection, and verify exact voltage, current, and decoupling requirements in the manufacturer datasheet. For battery-powered systems, calculate the average current from active-mode load, Deep Sleep current, wake-up frequency, and peripheral standby currents. Place the required input capacitor close to VDD and provide a clean return path from VSS. Do not infer regulator headroom from the family-level voltage range; use the selected operating frequency and temperature conditions when evaluating the power source.
Keep the 20-pin SSOP footprint faithful to the official package drawing and preserve the manufacturer-recommended decoupling and programming-test access. Because the package provides only 20 pins, assign multiplexing carefully before routing: analog inputs should be isolated from switching nodes, and communication or debug signals should not create unnecessary return-current paths. Treat the supplied I/O count as a device-level specification and confirm every selected signal and its alternate function against the package-specific pin table before fabrication.
The base device name and the complete ordering code are not interchangeable for production procurement. Specify the -I industrial grade and /SS package explicitly, and confirm the transport option separately when ordering. PIC24F16KA301-I/SO uses a different 20-pin SOIC footprint, while PIC24F16KA301T-I/SS is principally a packing option. Neither should be substituted during PCB assembly without confirming the exact mechanical drawing, pinout, temperature grade, firmware target, and reel or tube handling requirements.
For ADC, CTMU, or other sensitive analog measurements, separate analog and digital return paths as far as the package pin count allows, keep switching-regulator loops compact, and avoid routing high-current outputs beneath the MCU or analog input area. The 12-bit ADC and CTMU capability are useful, but their usable accuracy also depends on reference stability, source impedance, acquisition time, grounding, and PCB leakage. Validate the complete analog front end under the intended clock configuration and operating temperature rather than relying on converter resolution alone.
Informations de conformité
The supplied verified records identify an industrial -I grade and a lead-free 20-pin plastic package in one secondary listing, but they do not provide authoritative RoHS, REACH, AEC-Q100, halogen-free, or conflict-minerals statements. Compliance values therefore remain unknown rather than being inferred.
