PIC24F32KA302-E/SS - 32MHz 32KB XLP Microcontroller | Microchip
N.º da peça: PIC24F32KA302-E/SS ✓ AtivoPIC24F32KA302-E/SS Visão geral
A microcontroller is a programmable integrated circuit that combines a CPU core, nonvolatile program memory, working data memory, and peripherals on one device. The PIC24F32KA302 belongs to the PIC24F family and its PIC 16-bit RISC architecture is positioned between simple 8-bit controllers and more complex general-purpose processors. Its eXtreme Low Power feature set, including DSBOR, DSWDT, and RTCC operation in Deep Sleep mode, targets systems that spend substantial time between active processing intervals.
Three headline characteristics define this device. First, its PIC 16-bit RISC core operates at up to 32 MHz and is listed at 16 MIPS, providing deterministic control-oriented performance. Second, the memory configuration includes 32 KB of Flash, equivalent to 11K × 24 words, plus 2 KB of data RAM and 512 bytes of EEPROM. Third, the 28-SSOP package supports a broad peripheral mix without requiring the larger QFN or TQFP packages available on other family members.
The integrated 12-bit ADC supports analog measurements, while the CTMU provides a charge-timing measurement peripheral. Two I2C channels, an SPI interface, a UART, and six serial I/O ports allow the controller to connect sensors, displays, transceivers, memory devices, and service interfaces. These peripherals reduce the need for external interface ICs in small embedded systems. The CMOS implementation also reflects the family's emphasis on reducing both active and sleep-mode energy consumption.
Typical uses include industrial sensing nodes, battery-operated condition monitors, environmental measurement instruments, compact control panels, connected sensors, and low-power data loggers. The 32 MHz maximum operating frequency is appropriate for protocols and control loops requiring more computational headroom than an 8-bit MCU, while XLP peripherals support designs expected to spend extended periods in Deep Sleep.
Designers should preserve the exact 28-SSOP land pattern, verify the complete pin assignment against the manufacturer datasheet, and select decoupling and programming connections according to the device guidance. Supply-voltage and peripheral details not included in the verified search data must be confirmed before schematic release. This page combines verified product facts, qualified same-package alternatives, pricing availability notes, and application-oriented design guidance for faster component evaluation.

Aplicações típicas
PIC24F32KA302-E/SS é adequado para 6 aplicaçãos: Battery-Powered Environmental Sensor, Industrial Condition Monitor, Low-Power Data Logger, Compact Control Panel, CTMU-Based Capacitive Sensing, Connected IoT Sensor Node.
Battery-Powered Environmental Sensor
PIC24F32KA302-E/SS fits battery-powered environmental sensors because its PIC XLP architecture is optimized for low power, and DSBOR, DSWDT, and RTCC remain available in Deep Sleep mode. The 32 MHz, 16 MIPS core can handle sensor acquisition and local processing between long sleep intervals, while the 12-bit ADC supports analog measurements. Two I2C channels can connect digital sensors, and SPI can support higher-speed peripherals. Because no measured sleep current or wake-up time was supplied, battery-life estimates must be obtained from the datasheet and validated on the finished board.
Recomendado
Industrial Condition Monitor
PIC24F32KA302-E/SS is appropriate for compact industrial condition monitors where a 16-bit control architecture, 32 KB Flash, and 2 KB RAM provide useful processing and storage capacity in one device. The 12-bit ADC can monitor analog inputs, while dual I2C, SPI, and UART provide several paths for connecting sensors, local storage, and service equipment. The -E/SS suffix identifies the extended-temperature ordering option, but its exact temperature limits are not present in the verified excerpts. Industrial deployments should therefore confirm environmental ratings, isolation strategy, grounding, and transient protection against the manufacturer specifications.
Recomendado
Low-Power Data Logger
PIC24F32KA302-E/SS can serve as the control and storage platform for a low-power data logger because it combines 32 KB of Flash, 512 bytes of EEPROM, and a 16-bit PIC RISC core in a compact 28-SSOP package. The core supports active measurement and data-packaging tasks at up to 32 MHz, while XLP modes help reduce consumption during inactive periods. SPI can connect serial storage, while UART or I2C can support a host or external sensor. The verified information does not state endurance, retention, or write-cycle limits, so nonvolatile storage reliability must be checked before using EEPROM for frequently updated logs.
Recomendado
Compact Control Panel
PIC24F32KA302-E/SS can serve as the controller in a compact human-machine interface or control panel where six serial I/O ports and three principal serial interfaces provide flexible connectivity. UART or I2C can drive local displays and configuration devices, while SPI can support higher-speed peripherals. The 12-bit ADC is useful for monitoring panel analog inputs, and the 32 MHz core provides capacity for user-interface state handling. Exact I/O counts, alternate-function priorities, and electrical limits were not included in the verified excerpts, so pin multiplexing and board-level level shifting must be verified from the manufacturer package tables.
Recomendado
CTMU-Based Capacitive Sensing
PIC24F32KA302-E/SS is suitable for CTMU-based capacitive sensing because CTMU is explicitly listed as an integrated peripheral. The 16-bit controller can combine charge timing with application logic, and the 12-bit ADC supports related analog signal-chain requirements. This makes the device relevant to touch controls, level detection, and simple proximity-style products where avoiding a dedicated sensing ASIC simplifies the bill of materials. The verified excerpts do not specify CTMU channel counts, timing resolution, calibration procedure, or leakage limits. Those details, along with electrode routing and guarding techniques, must be taken directly from the manufacturer datasheet.
Recomendado
Connected IoT Sensor Node
PIC24F32KA302-E/SS fits connected IoT sensor nodes that need flexible serial connectivity and low standby energy. Dual I2C handles multiple low-speed peripherals, SPI supports a radio or serial memory, and UART provides a straightforward host or debugging path. Its 32 MHz PIC 16-bit core and 32 KB Flash allow application logic and communication buffering to coexist with the 12-bit ADC and CTMU. XLP support is especially relevant for nodes that transmit briefly and then sleep. RF performance, current consumption, and wake latency are not specified in the verified data and must be evaluated through the datasheet and a representative wireless design.

Notas de projeto
Use the manufacturer 28-SSOP land pattern and place all required input and output decoupling capacitors close to their associated device pins. Because the supplied excerpts identify the package but do not provide a verified pin table, do not infer capacitor locations from another SSOP-28 device. Cross-check pin numbers, exposed programming connections, analog grounds, and alternate functions against the official PIC24F32KA302 datasheet before releasing artwork.
Power-budget the design in both active and Deep Sleep states. The verified data confirms XLP operation and DSBOR, DSWDT, and RTCC functionality in Deep Sleep, but it provides no numeric quiescent-current or wake-time values. Measure current on representative hardware with the ADC, communications peripherals, pull resistors, sensors, and indicator loads connected; this prevents an MCU-only sleep calculation from overstating battery life.
Keep analog sensing routes associated with the 12-bit ADC short, quiet, and separated from switching or high-current paths. CTMU electrode networks are particularly sensitive to leakage and coupling, so follow the datasheet's recommended guarding and routing practices. If SPI is used near the ADC, control edge rates and return-current paths where practical, and verify the final design for noise, offset, and crosstalk rather than relying only on nominal 12-bit resolution.
Do not treat a shared SSOP footprint as proof that every suffix is interchangeable. Before replacing PIC24F32KA302-E/SS with PIC24F32KA302-I/SS, PIC24F32KA302T-I/SS, or PIC24F32KA302T-E/SSVAO, compare the manufacturer ordering table, temperature grade, qualification status, device ID, programming configuration, security features, and errata. The verified snippets establish family similarity but do not provide complete electrical comparisons for every alternative.
Informações de conformidade
The verified excerpts did not state material-compliance declarations for the exact ordering code. Compliance and qualification status must be confirmed on the official Microchip product page and current supporting documents.
