PIC24F08KL402-I/SO - 32MHz 16-Bit MCU | Microchip Technology
部品番号: PIC24F08KL402-I/SO ✓ 生産中PIC24F08KL402-I/SO 概要
A microcontroller is a programmable semiconductor that combines a processor core, nonvolatile program memory, working memory, I/O, and peripherals on one integrated circuit. The PIC24F08KL402 belongs to the PIC24F family of 16-bit flash microcontrollers and sits within the broader embedded-processing and embedded-control hierarchy. Its 16-bit architecture provides a larger processing register and instruction set than an 8-bit MCU, while the integrated nanoWatt XLP design emphasizes reduced current consumption during idle, sleep, and other low-activity operating modes.
The verified feature set includes 8 KB of flash organized as 2.75K by 24 words, 1 KB of SRAM, and 512 bytes of EEPROM. A 10-bit ADC supports analog measurement, while the 17 available I/O ports allow digital inputs, outputs, and communications links to be implemented in a compact design. The MSSP peripheral supports I2C or SPI communication, and the CCP/ECCP modules provide capture, compare, and PWM functions useful for motor control, timing, signal generation, and industrial automation.
The PIC24F08KL402-I/SO combines conventional 16-bit processing with low-power design and familiar PIC peripheral blocks. Its 32 MHz operating frequency provides a practical balance between control-loop responsiveness, general-purpose processing, and power-conscious design. The 28-lead SOIC package also offers a mechanically accessible option for through-hole assembly, programming, inspection, and repair in cost-sensitive industrial products.
Typical applications include compact industrial controllers, temperature and process-monitoring instruments, sensor-conditioning nodes, small motor-control boards, keypad interfaces, and communication bridges. In each case, the MCU can execute control logic, acquire analog measurements, drive PWM outputs, and communicate with sensors or peripherals through its integrated interfaces. The 3 V to 3.6 V supply range also allows the device to share a regulated 3.3 V system rail.
When designing around this MCU, verify the exact pin assignments and peripheral multiplexing from the manufacturer datasheet before assigning signals. Provide local decoupling close to the supply pins, keep sensitive analog and communications routes away from noisy switching paths, and confirm the required programming and configuration interface. The supplied data does not state the complete pin table, temperature limits, ADC channel count, or programming-tool details, so those values require confirmation from Microchip documentation.
This product record combines the verified manufacturer, distributor, and cross-reference information with a practical engineering assessment of the 16-bit core, nanoWatt XLP positioning, analog conversion, communications, and timer resources. It also distinguishes a confirmed same-package suffix alternative from package variants that cannot be treated as true drop-in replacements.

主な用途
PIC24F08KL402-I/SO の用途: 6 件s: Industrial Sensor Monitoring, Motor Control and PWM, I2C and SPI Sensor Interface, Cost-Sensitive Embedded Control, Communications Bridge, Low-Power Measurement Instrument.
Industrial Sensor Monitoring
The PIC24F08KL402-I/SO fits compact industrial sensor nodes because its 10-bit ADC provides analog measurement capability, while 17 I/O ports leave digital interface options for alarms, indicators, and discrete sensors. The 16-bit core and 32 MHz clock provide useful processing headroom for filtering, scaling, and control logic without moving to a larger MCU. Its 3 V to 3.6 V operating range supports a regulated 3.3 V rail, and the industrial suffix aligns with the stated application class. Place the device near the regulated supply and analog source, provide local bypass capacitance, and isolate analog inputs from switching nodes to preserve measurement quality.
Motor Control and PWM
The PIC24F08KL402-I/SO is appropriate for small motor-control and actuator-driver circuits because its CCP/ECCP peripherals support timing-intensive functions such as capture, compare, and PWM generation. A 32 MHz clock gives designers additional timing margin, while the 16-bit architecture is more capable than a basic 8-bit controller for managing position, speed, or duty-cycle logic. The 17 I/O ports can support control signals, fault inputs, and communication links. Because the MCU controls rather than directly drives most motors, the design still requires suitable power transistors, protection, current sensing, and thermal margin.
I2C and SPI Sensor Interface
The integrated MSSP peripheral makes the PIC24F08KL402-I/SO useful for connecting I2C or SPI sensors over a shared embedded board. Its 32 MHz clock can service protocol timing and application processing, while 8 KB of flash provides room for drivers, calibration logic, and communication routines. The 1 KB SRAM supports temporary packet handling and protocol buffers, and 17 I/O ports are available for shared buses, chip selects, status indicators, and configuration switches. Board design should include correct pull-up requirements for I2C, defined signal levels, controlled clock routing, and firmware that matches the selected bus mode.
Cost-Sensitive Embedded Control
The PIC24F08KL402-I/SO targets cost-sensitive products that need more control capability than an 8-bit MCU without using a high-end processor. Its 16-bit PIC24F architecture, 8 KB flash, 1 KB RAM, and integrated ADC reduce the number of external components needed for compact embedded controllers. The nanoWatt XLP feature set supports low-power operation, which is important in unattended or intermittently powered equipment. Developers should keep firmware modular, use the low-power modes intentionally, and verify wake-up behavior and timing because complete mode-current and wake-up figures were not included in the supplied data.
Communications Bridge
The PIC24F08KL402-I/SO can serve as a small protocol-conversion or sensor-to-controller bridge where local formatting, command processing, and status reporting are required. The MSSP peripheral provides an I2C or SPI interface to upstream and downstream devices, while the 32 MHz processor supports framing and response handling. Its 17 I/O ports can carry additional handshake, fault, or configuration signals. For reliable bridges, use a defined communication rate with timing margin, isolate long external lines appropriately, and confirm that the selected connector and transceiver voltage levels are compatible with the MCU’s 3.3 V operating environment.
Low-Power Measurement Instrument
The nanoWatt XLP positioning of the PIC24F08KL402-I/SO suits battery-operated measurement instruments that alternate between active measurement and low-power waiting. The 10-bit ADC handles basic analog sensing, and the 16-bit core can perform scaling and digital filtering within the available 1 KB SRAM and 8 KB flash. Low-power firmware can use the MCU’s sleep-oriented operating modes to reduce consumption between readings. A practical implementation must measure the complete current budget, including sensors, pull resistors, indicator LEDs, and regulators, because the verified source only confirms the XLP feature and does not provide quantified mode-current figures.

設計ノート
Place all decoupling capacitors immediately adjacent to the MCU supply pins, with the shortest possible return path to the associated ground pins. Although the verified data confirms a 3 V to 3.6 V supply range, capacitor values, ESR requirements, and startup limits must be taken from the manufacturer datasheet. Route the 3.3 V distribution away from analog and communication traces to reduce supply coupling.
Keep analog inputs associated with the 10-bit ADC away from switching nodes, motor-drive traces, inductor connections, and clock edges. Use a quiet-ground strategy appropriate to the board architecture, and preserve a continuous ground reference beneath signal paths. The verified data confirms ADC resolution but not the channel count or acquisition requirements, so verify analog routing against the complete pin and electrical tables before layout release.
Do not treat all PIC24F08KL402 package suffixes as drop-in alternatives. The -I/SP version is a 28-pin SPDIP package, while -E/SS is a different package option; neither can replace the -I/SO without a board-level package change. For -E/SO, confirm the E-versus-I temperature-grade requirements and all electrical limits in Microchip documentation before approving it as a substitution.
Design the power budget for both active operation and low-power periods. The nanoWatt XLP feature supports low-power use, but the supplied data does not quantify active current, sleep current, or peripheral leakage. Measure the assembled system rather than relying on the MCU value alone, because sensors, pull resistors, LEDs, level translators, and the regulator can dominate total current in a compact embedded product.
For I2C or SPI communication implemented by the MSSP peripheral, define pull-ups only where required by the selected bus topology and keep clock or data traces away from switching power stages. The verified sources do not specify supported bus rates or timing margins, so firmware timing must be checked against the datasheet and the slowest peripheral on the bus.
コンプライアンス情報
The supplied verified pages identify the product as active and industrial-grade, but they do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred.
