PIC24F08KL402-E/SS - 32MHz 16-bit MCU | Microchip Technology
Référence : PIC24F08KL402-E/SS ✓ ActifPIC24F08KL402-E/SS Présentation
A microcontroller is a semiconductor device that integrates a processor core, program memory, data memory, and peripherals into one package. The PIC24F08KL402 belongs to the PIC24F family of 16-bit Flash microcontrollers, combining a general-purpose embedded-control hierarchy with low-power design features. Its 28-SSOP package is intended for compact, cost-sensitive embedded systems where board area, flash memory, analog measurement, and serial connectivity must be balanced.
The PIC24F08KL402 provides 8 KB of Flash program memory organized as 2.75K x 24 words, 1 KB of RAM, and 512 bytes of EEPROM according to distributor product information. The integrated 10-bit ADC supports analog measurement tasks, while comparators provide hardware threshold detection. CCP and ECCP peripherals add capture, compare, and PWM capabilities for timing, motor-control, and signal-generation functions.
Its MSSP peripheral supports I2C and SPI, making the device appropriate for sensors, display drivers, memory devices, and other serial peripherals. The 32 MHz maximum operating frequency provides additional computation and timing headroom compared with slower general-purpose microcontrollers, while the small 8 KB Flash footprint keeps the device economical for compact control products.
Typical applications include low-cost sensor nodes, industrial monitoring equipment, small motor-control systems, consumer appliances, and embedded control boards requiring I2C or SPI connectivity. The PIC24F08KL402-E/SS suffix identifies the SSOP package and E temperature-grade ordering option, while the -I/SS ordering variant provides a separate industrial temperature-grade option.
Designers should verify the complete pin allocation, operating-voltage limits, ADC performance, and peripheral electrical limits against the manufacturer datasheet before layout. The 28-SSOP footprint requires careful spacing between adjacent pins, and the 8 KB Flash limit should be checked against application code size, bootloader requirements, and library overhead. Commercial availability and pricing should also be confirmed at the time of purchase because the supplied distributor search results establish product listings but do not provide a stable price matrix.
This page combines the verified manufacturer and distributor facts with practical application guidance, package considerations, and an honest assessment of drop-in replacement options. It is intended to help engineers compare the PIC24F08KL402-E/SS with related 28-SSOP configurations before committing a PCB design.

Applications typiques
PIC24F08KL402-E/SS convient pour 6 applications: Industrial Sensor Monitoring, Small Motor and PWM Control, Consumer Appliance Control, I2C and SPI Sensor Node, Embedded Data Acquisition, Low-Power Remote Control.
Industrial Sensor Monitoring
The PIC24F08KL402-E/SS fits compact industrial monitoring systems that require analog measurement and serial sensor connectivity. Its 10-bit ADC can acquire process or environmental signals, while the MSSP peripheral supports I2C and SPI for digital sensors, signal conditioners, and remote sensor nodes. The 32 MHz core provides useful timing headroom for filtering, diagnostics, and communication handling. With 1 KB RAM and 8 KB Flash, the device is best suited to focused monitoring tasks rather than feature-heavy edge analytics. The 28-SSOP package also helps reduce board width in densely populated industrial control assemblies, although designers should verify input limits and pin multiplexing against the datasheet.
Recommandé
Small Motor and PWM Control
PIC24F08KL402-E/SS is appropriate for small embedded-control mechanisms that need accurate pulse generation and threshold detection. Its CCP and ECCP peripherals support capture, compare, and PWM functions, while the comparators can assist with limit detection or control-loop inputs. The 32 MHz operating frequency gives designers more timing margin than many entry-level 8-bit controllers, and the 16-bit architecture can simplify fixed-point calculations for duty-cycle management. Its 8 KB Flash and 1 KB RAM suit compact motor-control firmware, although the application still needs suitable gate drivers, protection, and power circuitry because the MCU does not directly replace external switching hardware.
Recommandé
Consumer Appliance Control
The PIC24F08KL402-E/SS can serve as the embedded controller in cost-sensitive appliances that combine simple analog sensing, timing, and serial communication. Its 10-bit ADC may monitor controls or analog feedback, CCP/ECCP can generate timing and PWM signals, and MSSP can connect to displays, sensors, or memory devices through I2C or SPI. nanoWatt XLP is valuable when the appliance spends substantial time idle or operates in a low-power standby state. The 28-SSOP package helps limit board width, while 8 KB Flash, 1 KB RAM, and 512 bytes of EEPROM provide enough resources for a focused appliance controller when code size is managed carefully.
Recommandé
I2C and SPI Sensor Node
PIC24F08KL402-E/SS is well matched to distributed sensor nodes that aggregate readings from digital sensors over I2C or SPI. The MSSP peripheral provides dedicated serial connectivity, avoiding the need for a separate communications IC, while the 10-bit ADC can support an additional local analog measurement. At 32 MHz, the controller can service serial transactions, apply calibration, and manage periodic sampling within a compact firmware routine. The 512-byte EEPROM can retain configuration or calibration data, and the 1 KB RAM supports short data buffers. Power-budget decisions should use the manufacturer nanoWatt XLP operating modes, particularly for battery-operated or energy-harvesting installations.
Recommandé
Embedded Data Acquisition
The PIC24F08KL402-E/SS can support compact data-acquisition front ends where analog inputs, timing, and local control must be integrated on a small board. Its 10-bit ADC provides a practical measurement interface for proportional controls and process signals, and the 32 MHz processor allows the firmware to perform calibration, filtering, and threshold checks. CCP/ECCP peripherals can synchronize sampling or generate trigger and reference signals, while MSSP permits connection to external converters or storage. The 8 KB Flash limit means high-resolution capture buffers, extensive logging, and heavyweight algorithms should be offloaded or avoided; the 1 KB RAM is suitable mainly for short acquisition windows and tightly bounded working sets.
Recommandé
Low-Power Remote Control
PIC24F08KL402-E/SS is suitable for battery-operated remote controls and compact command modules because nanoWatt XLP targets low-power operation and the 28-SSOP package supports space-constrained assemblies. The 32 MHz core and 1 KB RAM permit responsive handling of button or encoder input, while CCP/ECCP can manage timing, debouncing, or indicator drive. The MSSP block can add an I2C or SPI interface for a display, sensor, or communication companion without occupying a separate package. Firmware should use the low-power modes intentionally and disable unused peripherals. Because the verified snippets do not provide sleep-current figures or retention behavior, those values must be taken from the official datasheet before sizing the battery.

Notes de conception
Use the manufacturer's nanoWatt XLP mode-selection procedure to minimize current consumption in battery-powered designs. Disable unused peripherals, avoid continuous timer activity, and place the MCU into the lowest suitable sleep mode only after confirming which timers, MSSP transactions, and ADC samples may continue. The supplied web results confirm nanoWatt XLP but do not provide sleep-current figures, so battery sizing must use the operating-current and wake-up data from the official datasheet.
The 28-SSOP package has a 0.209-inch, or 5.30 mm, body width and requires careful land-pattern and solder-clearance planning. Follow the exact Microchip package drawing rather than creating a footprint from body width alone. Route sensitive analog inputs away from switching nodes and high-current return paths, keep the ground reference continuous beneath the device where practical, and verify that assembly access and inspection clearance remain adequate for the chosen board density.
Do not assume that every same-package PIC24F part is firmware- and peripheral-compatible. Before choosing PIC24F08KL401, PIC24F08KL400, or a temperature-grade alternative, compare the complete pin table, ADC channels, timer mappings, MSSP behavior, memory limits, configuration bits, and electrical specifications. The verified web results directly establish the KL402-I/SS feature set, while the other same-family candidates were enumerated from permitted same-brand family knowledge and still require datasheet-level confirmation.
Plan analog and digital functions deliberately around the MCU pin constraints. Place the ADC input source close to the relevant pins, keep traces short, and route them away from PWM outputs, relays, inductors, and switching-regulator nodes. If the application combines MSSP communication with sensitive analog measurement, provide a controlled ground and power layout so serial switching activity does not dominate the measurement floor. The supplied ADC resolution is 10-bit, making reference stability and analog conditioning important to useful accuracy.
Informations de conformité
The verified search results do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for this ordering code. AEC-Q100 is treated as not applicable because the verified material describes an industrial MCU rather than an automotive-qualified device.
