PIC24F32KA301-E/SS - 16-bit 32MHz XLP Microcontroller | Microchip
Référence : PIC24F32KA301-E/SS ✓ ActifPIC24F32KA301-E/SS Présentation
A microcontroller is a compact embedded-processing device that combines a CPU core, program memory, data memory, and peripherals on one integrated circuit. The PIC24F32KA301 belongs to the general-purpose 16-bit flash microcontroller family and is positioned within the broader hierarchy of embedded controllers, microcontrollers, and semiconductors. Its XLP architecture emphasizes low current consumption and battery life, while the programmable peripherals support analog measurement, timing, communication, and control functions in embedded systems.
The PIC24F32KA301-E/SS provides a practical balance of processing speed, memory, and analog capability. Its 32 MHz operating speed supports 16 MIPS operation, while 32 KB of flash provides storage for firmware and application code. The 12-bit ADC and CTMU peripheral extend the device beyond basic digital control, enabling sensing and measurement functions in instruments, sensors, and portable products. The 20-pin SSOP package also offers a compact surface-mount format for space-constrained boards.
Deep Sleep support is central to the PIC24F32KA301 use case. The manufacturer highlights DSBOR, DSWDT, and RTCC operation in Deep Sleep mode as features that support low-power performance when the system does not need continuous processing. This makes the device relevant to battery-operated products, portable monitors, sensing nodes, and embedded equipment where standby energy consumption is as important as active processing capability.
Typical applications include low-power sensor nodes, battery-powered medical and industrial instruments, compact control boards, and connected embedded products. The MCU can combine ADC-based measurement with CTMU support and its embedded flash memory, allowing a compact design to handle sensing, control, and local firmware functions. Engineering teams should confirm the required peripherals, pin multiplexing, programming method, and low-power mode behavior against the manufacturer datasheet before finalizing the PCB.
For implementation, begin by reviewing the 20-pin SSOP pin assignment, programming pins, and power-entry requirements in the manufacturer documentation. Keep power and decoupling layout compact, connect programming access according to the recommended programming circuit, and validate wake-up behavior in the intended battery system. This page combines the verified product characteristics, package information, application guidance, and available cross-reference candidates to support faster component selection and board-level planning.

Applications typiques
PIC24F32KA301-E/SS convient pour 6 applications: Battery-Powered Sensor Node, Portable Medical Monitoring, Industrial Control Module, Portable Instrument Control, Smart Home Sensor, Energy Metering Front End.
Battery-Powered Sensor Node
The PIC24F32KA301-E/SS fits compact battery-powered sensor nodes because its XLP-focused architecture is designed for power-constrained operation. At up to 32 MHz with 16 MIPS throughput, the 16-bit PIC24 core can process measurements and control logic without requiring a larger processor. The 12-bit ADC supports analog sensing, while DSBOR, DSWDT, and RTCC operation in Deep Sleep mode help the design reduce consumption between events. Developers should select the active and sleep duty cycle from the manufacturer current specifications and validate the complete battery budget on the assembled PCB.
Recommandé
Portable Medical Monitoring
The PIC24F32KA301-E/SS is suitable for portable monitoring equipment where a compact 16-bit controller, local memory, and low-power operation are important. Its 12-bit ADC can acquire analog sensor signals, 32 KB of flash stores application firmware, and 2 KB of RAM supports working data and control state. Deep Sleep operation can reduce energy use between measurements or user interactions. For medical equipment, engineers must also verify the applicable operating limits, safety requirements, external front-end design, and electrical isolation requirements rather than treating the MCU alone as a medical certification.
Recommandé
Industrial Control Module
The PIC24F32KA301-E/SS can support compact industrial control and data-acquisition modules that need a 16-bit RISC core without a high-pin-count processor. The device combines 32 MHz operation, a 12-bit ADC, CTMU measurement support, and 32 KB of flash in a 20-pin SSOP package. These resources allow one controller to handle sensor input, threshold logic, actuator supervision, and local diagnostics. Confirm the E-grade operating-temperature range and supply limits against the enclosure environment, and provide suitable transient protection and isolation at field interfaces.
Recommandé
Portable Instrument Control
The PIC24F32KA301-E/SS is appropriate for portable test and measurement instruments that combine digital control with low-level analog observation. Its 12-bit ADC and CTMU support can be used in measurement front ends, while the 16-bit CPU manages calibration, display updates, button input, and instrument control. The 32 KB program memory and 2 KB RAM provide enough architecture for compact control firmware, while Deep Sleep modes can reduce consumption between measurement cycles. Analog accuracy still depends on reference quality, input filtering, calibration, grounding, and careful separation of noisy switching paths.
Recommandé
Smart Home Sensor
The PIC24F32KA301-E/SS works well in compact smart-home sensing nodes where low standby consumption, local measurement, and modest processing requirements are primary. Its XLP design and Deep Sleep support allow the MCU to wake for a sensor reading, process the result, and return to a low-energy state. The 12-bit ADC handles analog inputs, CTMU adds specialized measurement capability, and the small 20-pin SSOP package helps fit compact sensor boards. Low-power Wi-Fi or Bluetooth modules should be controlled carefully so that radio activity does not dominate the calculated battery life.
Recommandé
Energy Metering Front End
The PIC24F32KA301-E/SS can serve as the local control and measurement processor in a compact energy-metering front end. Its 12-bit ADC and CTMU support are useful for acquiring low-level analog signals, while 16 MIPS performance permits simultaneous timing, filtering, and register management. The 32 KB of flash stores measurement and calibration routines, and the 2 KB RAM supports short-term buffering and communication formatting. Use dedicated sensing, isolation, and signal-conditioning components where required, and validate metering accuracy across the complete input range and temperature envelope.

- Preserves the core PIC24F32KA301 architecture (vs PIC24F32KA301T-I/SS)

Notes de conception
Route the PIC24F32KA301-E/SS power pins and decoupling network using the manufacturer recommended layout in the datasheet. Keep the supply and ground connections short, place high-frequency bypass capacitors close to the device, and provide a clean return path for ADC and CTMU signals. Because the package uses a 0.65 mm pitch, inspect the PCB assembly design for solder bridging and confirm that the chosen land pattern matches the 20-pin SSOP dimensions.
Build the battery and standby-power budget from the active, sleep, and Deep Sleep current values in the manufacturer datasheet. Account for the MCU supply current, ADC and CTMU activity, pull networks, external sensors, regulator quiescent current, and leakage through protection components. The verified information identifies XLP and Deep Sleep capabilities, but it does not provide numerical current ratings, so use the device documentation for the final power calculation.
Do not substitute the package drawing from a 28-pin or 44-pin PIC24F32KA member for the 20-pin SSOP version. Confirm pin 1 orientation, power pins, programming pins, ADC channels, CTMU connections, and alternate I/O functions against the exact 20-pin pin-description table. Also verify the operating-temperature grade required by the product before using a different ordering suffix.
Separate analog inputs, CTMU sensing nodes, and reference connections from digital switching and programming traces. Use a quiet ground reference for the measurement section, route sensitive inputs away from high-current loads, and apply filtering appropriate to the sensor bandwidth. If the analog signal source has high source impedance, account for input leakage, sampling charge, and acquisition time in the firmware rather than treating the 12-bit ADC resolution as guaranteed accuracy.
Informations de conformité
The verified product excerpts do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The -E ordering suffix identifies the product's specified temperature grade, but it does not by itself establish AEC-Q100 qualification.
