PIC24F08KL402-I/SS - 32MHz 16-Bit nanoWatt XLP MCU | Microchip Technology
料号： PIC24F08KL402-I/SS ✓ 量产中PIC24F08KL402-I/SS 概述
A PIC24 microcontroller is a general-purpose 16-bit embedded controller within the broader semiconductor and microcontroller hierarchy. Unlike an 8-bit MCU, the PIC24 architecture provides a wider register and data path suited to control loops, protocol handling, and compact sensor-processing tasks. The PIC24F08KL402 combines that core with nanoWatt XLP power-management functions, MSSP support for I2C or SPI, and CCP/ECCP peripherals for flexible timing and capture or compare functions.
The verified device data identifies a 32 MHz operating frequency, 8 KB of Flash memory organized as 2.75K by 24 words, and 1 KB of data RAM. Its 10-bit ADC supports embedded analog measurement, while two comparators, six timers, and a watchdog timer broaden the on-chip control resources. MSSP peripherals support I2C and SPI connectivity, and ECCP provides additional control flexibility where the application requires more dedicated capture, compare, or pulse-width resources.
The PIC24F08KL402 is a CMOS device that combines power-on reset and brown-out reset protections with low-power design features. Its 512-byte EEPROM gives the firmware a nonvolatile location for calibration values, configuration data, or counters that must survive a power cycle. The industrial-temperature suffix in the ordered MPN identifies the -I/SS ordering code, while the SSOP package provides 28 leads for surface-mount assembly.
Typical applications include industrial sensor nodes, compact environmental monitors, motor or actuator controllers, low-power data-acquisition modules, and connected equipment using SPI or I2C peripherals. Its 10-bit ADC supports sensor interfaces, while the timer and CCP resources suit periodic measurement, PWM generation, and timing tasks. The combination of 32 MHz processing and 1 KB of RAM is appropriate for small control loops rather than memory-intensive edge-computing workloads.
Designers should verify the exact operating-voltage range, ADC performance, pin multiplexing, and timing limits in the manufacturer datasheet before layout release. Decoupling, programming, and clock considerations should follow the device's recommended hardware guidelines. Because the verified data does not provide a complete pin table, this page does not reconstruct or guess individual pin assignments.
This page combines verified distributor specifications, manufacturer product information, and explicitly sourced drop-in references with practical design guidance. It distinguishes confirmed electrical and peripheral data from unavailable details, helping engineers compare the PIC24F08KL402-I/SS without introducing unsupported specifications.

典型应用
PIC24F08KL402-I/SS 适用于 6 应用s: Industrial Sensor Nodes, Environmental Monitoring, Motor and Actuator Control, Low-Power Data Acquisition, SPI and I2C Connected Equipment, Cost-Sensitive Embedded Control.
Industrial Sensor Nodes
PIC24F08KL402-I/SS fits compact industrial sensor nodes that require a 10-bit ADC, local control logic, and low-power operation without a high-cost MCU. Its 32 MHz 16-bit PIC24 core can handle sensor conditioning, threshold decisions, filtering, and communication scheduling, while 1 KB of RAM provides working space for sampled values and protocol state. The nanoWatt XLP feature is especially relevant to remote or battery-assisted nodes that spend substantial time between measurements. A practical design uses the ADC for analog inputs, MSSP for I2C or SPI sensors, and the timers for periodic sampling. The verified information does not provide exact ADC timing or operating-current values, so those limits must be checked against the datasheet before finalizing the power budget and sampling rate.
推荐
Environmental Monitoring
PIC24F08KL402-I/SS is suitable for environmental monitoring modules that combine analog measurements, digital sensors, and periodic data transfer. The 10-bit ADC can sample resistive, capacitive, or other analog sensor outputs, while the MSSP block can connect I2C or SPI devices such as digital temperature, humidity, or pressure sensors. Its six timers support periodic acquisition, debounce intervals, and communication timeouts, and the CCP/ECCP resources can assist with additional timing functions. With 8 KB of Flash, firmware size must be managed carefully, but the 1 KB RAM and 512-byte EEPROM provide useful nonvolatile storage for calibration parameters. nanoWatt XLP operation can reduce energy use between measurement cycles, although actual battery life depends on the verified duty cycle, supply voltage, and device-specific current data.
推荐
Motor and Actuator Control
PIC24F08KL402-I/SS can serve as the controller for small motors, valves, relays, and electromechanical actuators where compactness and mixed peripheral support are valuable. The CCP/ECCP resources are suitable for pulse-width modulation, input capture, and timing functions associated with motor or actuator control, while the six timers provide scheduling for commutation, debounce, and fault handling. Its 32 MHz 16-bit architecture offers more arithmetic headroom than a basic 8-bit controller for proportional control and protection logic. The two comparators may assist with threshold or feedback monitoring, and the ADC can measure current or position-related signals. Engineers must add appropriate driver circuitry, protection, and filtering; verify the exact CCP/ECCP channel assignments, PWM resolution, and pin multiplexing in the manufacturer datasheet before PCB layout.
推荐
Low-Power Data Acquisition
PIC24F08KL402-I/SS is appropriate for small data-acquisition modules that need flexible analog input support and serial connectivity. The 10-bit ADC enables repeated measurements from resistive dividers, current-sense outputs, or other analog signals, while MSSP provides an interface to external sensors, converters, or storage devices using I2C or SPI. Six timers help organize acquisition intervals, sampling deadlines, and communication transfers, and the CCP/ECCP peripherals can provide dedicated timing or capture functions. The 1 KB RAM is suitable for modest buffering rather than large sample sets, while the 512-byte EEPROM can retain calibration constants. nanoWatt XLP functionality helps reduce consumption between acquisition events, but a defensible power calculation still requires verified active, idle, and sleep currents from the manufacturer datasheet.
推荐
SPI and I2C Connected Equipment
PIC24F08KL402-I/SS fits connected embedded equipment that needs both general-purpose control and flexible serial communications. The MSSP peripherals support I2C and SPI, allowing the MCU to connect to sensors, displays, flash memory, transceivers, or other digital components through one dedicated serial architecture. Its 32 MHz 16-bit PIC24 core can service protocol overhead and local control tasks, while the 10-bit ADC handles any analog supervisory signals. The 8 KB Flash footprint is adequate for compact protocol stacks and application logic, although firmware budgeting remains important. Timers can establish bus timeouts or periodic housekeeping tasks, and ECCP can handle specialized timing needs. Exact pin multiplexing, peripheral-instance availability, and communication timing must be checked in the PIC24F08KL402 datasheet before assigning board functions.
推荐
Cost-Sensitive Embedded Control
PIC24F08KL402-I/SS targets cost-sensitive embedded products that need more control capability than an 8-bit MCU without moving to a higher-memory platform. The 16-bit PIC24 RISC core operates at up to 32 MHz and is supported by 1 KB of RAM, 8 KB of Flash, 512 bytes of EEPROM, and a 10-bit ADC. Its MSSP, CCP/ECCP, timers, comparators, watchdog timer, power-on reset, and brown-out reset create a practical set of resources for compact controllers. This makes the device useful in appliance controls, simple building equipment, instrumentation, and dedicated interface modules. The main design trade-off is limited memory, which requires disciplined code size and carefully selected data structures. Power and thermal analysis should be modest at 32 MHz, but package-level dissipation still depends on clock activity, load, and voltage.

设计说明
Verify the supply voltage range, active current, sleep current, and brown-out reset thresholds in the manufacturer datasheet before defining the power tree. The 3 V value in the verified listings describes the ADC reference and should not be treated as the complete operating-voltage range. Place the required input and output decoupling capacitors directly beside the corresponding SSOP pins, and use the manufacturer layout guidance to control switching-current paths through the device ground pins.
Do not assign the MSSP, ADC, CCP/ECCP, comparator, timer, or programming functions until every alternate-function mapping has been checked against the datasheet pin table. The supplied search results confirm a 28-pin SSOP package but do not provide the complete numbered pinout, so consulting the official pin diagram is mandatory. Keep sensitive analog inputs away from high-current switching nodes, provide a quiet ground return, and follow the recommended external-circuitry and decoupling arrangements.
Avoid treating the 8 KB Flash, 1 KB RAM, or 512-byte EEPROM allowances as unlimited and include library code, interrupt vectors, stack depth, calibration data, and communication buffers in the memory budget. PIC24F08KL402T-I/SS is described as a complete replacement for PIC24F08KL402-I/SS, but suffix changes can encode grade or ordering requirements. Confirm the exact temperature range, qualification status, and marking before approving a substitution for production.
For battery-powered sensor nodes, use the nanoWait XLP capability only after establishing a measured duty cycle and confirming every peripheral's behavior in the intended sleep mode. The verified data does not provide active or sleep-current figures, so battery-life estimates would be speculative. Disable unused peripherals, schedule ADC and serial conversions explicitly, and retain the brown-out reset and watchdog functions if the system can recover safely from power faults.
合规信息
The supplied verified search results do not state the regulatory status of PIC24F08KL402-I/SS. Compliance attributes must be confirmed from the current Microchip product declaration or package documentation.
