PIC24F16KL402-E/SS Présentation
A microcontroller is a compact embedded-processing system that combines a processor core, memory, peripherals, and I/O in one integrated circuit. The PIC24F belongs to the 16-bit MCU category and sits within the broader embedded-controller and semiconductor hierarchy. Compared with an 8-bit MCU, the 16-bit architecture supports higher computational throughput and more efficient handling of control logic, while retaining a cost-conscious design suited to appliances, industrial controls, and portable products.
PIC24F16KL402-family devices emphasize eXtreme Low Power consumption through nanoWatt XLP features, allowing energy-efficient operation in cost-sensitive embedded products. The family includes PIC18-style peripherals such as MSSP for I2C or SPI communication and CCP/ECCP modules for capture, compare, PWM, and motor-control functions. These integrated peripherals reduce external hardware requirements and simplify firmware implementation for common control tasks.
The verified product listing identifies 16 KB of Flash organized as 5.5K x 24 words. Other distributor snippets describe the PIC24F core, 8 KB of RAM, 512 bytes of EEPROM, and a 3 V operating class. The manufacturer describes the family as economical, low-pin-count, low-power devices aimed at applications that require more computational capability than an 8-bit platform. One product source also describes a 2 V to 3.3 V device range, while the available verified material does not establish every detailed electrical limit.
Typical uses include portable consumer products, low-cost medical testing and dispensing equipment, safety and security systems, and industrial or automotive controls. The 28-pin SSOP footprint is useful where a small package and mixed analog, digital, communication, and timing resources are needed. Designers should verify the exact pin function, peripheral availability, clock configuration, and operating limits against the manufacturer family data sheet before releasing a PCB or production firmware.
A key design consideration is preserving low-power behavior after peripheral configuration. Unused pins, oscillators, timers, communications modules, and analog blocks should be initialized deliberately so the firmware does not prevent the intended nanoWatt XLP duty cycle. Decoupling, programming, clock stability, and unused-pin handling should follow the relevant Microchip guidance rather than relying on assumptions from a different PIC24F family member.
This page consolidates the verified manufacturer, distributor, and cross-reference sources into an engineering-oriented overview of the PIC24F16KL402-E/SS, including available pricing, package details, application guidance, and a conservative assessment of verified drop-in alternatives.

Applications typiques
PIC24F16KL402-E/SS convient pour 6 applications: Portable Consumer Devices, Medical Test and Dispensing Equipment, Industrial Control and Automation, Safety and Security Equipment, I2C and SPI Sensor Hubs, Motor and PWM Control.
Portable Consumer Devices
The PIC24F16KL402-E/SS fits portable consumer products that need more control capability than an 8-bit MCU without paying for a higher-end processor. Its 16-bit PIC24F core operates up to 32 MHz, while 16 KB of Flash, 8 KB of RAM, and 512 bytes of EEPROM provide working space for firmware, configuration, and retained data. The nanoWatt XLP feature is especially relevant when the product spends most of its time in a low-power state. In a portable media accessory or sports-equipment controller, the MCU could supervise user inputs, drive indicators, and sleep between events. The primary design consideration is firmware discipline: unused oscillators, timers, serial modules, and I/O pins must be configured to avoid increasing sleep current. The 28-pin SSOP also permits a compact board outline, although exposed pad, soldering, and signal-routing guidance must follow the package documentation.
Recommandé
Medical Test and Dispensing Equipment
PIC24F16KL402-E/SS is appropriate for cost-sensitive medical testing, dispensing, or diagnostic accessories when the required temperature grade and regulatory validation are satisfied. Its 16-bit architecture and 32 MHz maximum frequency provide useful throughput for sequencing sensors, driving indicators, controlling buttons, and maintaining timing between measurement operations. The verified family description specifically identifies disposable low-cost medical testers, dispensers, and inhalers as target areas. Embedded designers can assign MSSP to I2C or SPI sensors and use CCP/ECCP for timing or PWM-related functions, reducing the need for separate interface ICs. Safety-critical decisions must remain outside the scope of generic MCU marketing: validate accuracy, fault behavior, electrical isolation, and applicable medical requirements for the complete product. The extended-temperature ordering option should be checked against the actual enclosure temperature and component qualification.
Recommandé
Industrial Control and Automation
The PIC24F16KL402-E/SS can serve as the local controller in a compact industrial machine, sensor node, or process-control module. At up to 32 MHz, the 16-bit core is suitable for deterministic control loops, state-machine logic, and coordination of multiple I/O lines, while the MSSP peripheral supports I2C or SPI links to sensors and actuators. CCP and ECCP can support timing, compare, PWM, and motor-related functions where the exact pin assignment and peripheral implementation permit. The 28-pin SSOP package helps limit board area in space-constrained control boards. Engineers should budget I/O voltage levels, isolation, surge protection, grounding, and actuator drive separately; the MCU does not replace power-stage hardware. Its extended-temperature suffix should be matched to the measured enclosure temperature, and production firmware should exercise watchdog, brownout, and safe-state behavior to prevent an unsafe output after a fault.
Recommandé
Safety and Security Equipment
PIC24F16KL402-E/SS is well matched to low-cost safety, security, and access-control accessories that need low standby power and a compact package. The 16-bit core can execute sensor state machines, timing sequences, keypad handling, lock or alarm logic, and communication tasks at up to 32 MHz. Its 8 KB of RAM supports working buffers and protocol state, while 512 bytes of EEPROM can retain configuration values subject to the family's endurance requirements. The MSSP peripheral allows connection to I2C or SPI sensors and secure elements without dedicating a separate interface device. Security designs should add device authentication, protected keys, event logging, and secure boot where required rather than treating general-purpose firmware security as automatic. For battery-backed installations, firmware-controlled sleep modes are essential, and brownout behavior must be designed so locks, alarms, and access outputs enter a defined state during power loss.
Recommandé
I2C and SPI Sensor Hubs
PIC24F16KL402-E/SS can act as a compact sensor-hub controller when a design needs local logic for several I2C or SPI sensors. The MSSP peripheral is explicitly positioned as a PIC18-style feature within this PIC24F family, providing a practical path to shared-bus acquisition, device configuration, and periodic sampling. The 16-bit core can preprocess measurements, apply thresholds, and forward status over another interface without offloading every task to a higher-power processor. In a wearable or environmental monitor, the MCU could combine motion or temperature samples and activate a radio only at reporting intervals. Designers must verify the exact MSSP channel count, bus voltage, pin multiplexing, and address limitations in the 28-pin SSOP variant. Pull-up sizing, bus capacitance, ground return, and low-power bus shutdown are especially important when the system is battery powered and the peripheral rail can be switched independently.
Recommandé
Motor and PWM Control
PIC24F16KL402-E/SS is suitable for small motor-control, actuator, or PWM-based load modules where the CCP/ECCP peripherals and 32 MHz processing headroom provide useful timing capability. A cost-sensitive fan, pump, valve, or position-control product can use PWM outputs to regulate speed or duty cycle, read feedback through an input channel, and supervise timeout conditions in firmware. The MCU should not directly drive an inductive motor load; external transistor or MOSFET stages, current limiting, flyback protection, and an appropriate power supply remain necessary. The verified material confirms CCP/ECCP functionality but does not establish every channel, timer, or pin assignment for the 28-pin package, so those details must be checked in the family data sheet. Firmware should include defined startup, coast, braking, and fault states, and hardware should disable the actuator whenever reset or brownout conditions could otherwise leave the power stage in an unsafe state.

Notes de conception
Use the manufacturer family data sheet to select the operating voltage and decoupling network for the exact suffix. The verified material identifies a 2 V to 3.3 V device range and a 3 V class, but it does not provide a complete pin-level decoupling table. Place the required input capacitors close to the supply pins, maintain short ground returns, and confirm that any switched sensor or communications rail cannot back-feed an unpowered MCU. Validate sleep current only after unused peripherals, oscillator loops, and I/O states have been initialized for low-power operation.
Reserve the PCB footprint from the manufacturer package drawing rather than inferring it from the 28-pin count alone. Confirm pin 1 orientation, lead pitch, body width, solderable lead length, and any exposed thermal pad requirement in the 28-pin SSOP documentation. Keep analog and digital returns organized, route sensitive sensor inputs away from PWM and high-current switching paths, and provide local bypass capacitance at the MCU. The verified data does not include a complete pin-by-pin mapping, so schematic and layout review against the official pin table is mandatory.
Do not substitute a different suffix solely because the package appears identical. The E, I, and T ordering codes can represent different temperature or qualification conditions, while /SS, /SO, and /ML identify ordering or packaging variants whose exact mechanical details must be verified. For firmware reuse, retain the same peripheral set and pin configuration only after checking the package-specific pin table. Treat the available alternatives as family candidates rather than unconditional replacements, and obtain a current manufacturer declaration or distributor record before approving a substitution.
PIC24F peripherals can remain active after application logic becomes idle if initialization or sleep entry is incomplete. Firmware should explicitly disable unused MSSP, CCP/ECCP, timer, ADC, comparator, oscillator, and digital I/O resources before entering the intended low-power mode. Re-enable only the modules required for the next wake event. Validate wake sources, oscillator start-up timing, brownout behavior, and peripheral state with a debugger and current measurement on the finished board rather than relying on nominal sleep-current figures.
Informations de conformité
The verified manufacturer and distributor results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for PIC24F16KL402-E/SS. Application examples in the family documentation do not by themselves establish AEC-Q100 qualification.
