PIC24F16KM102-E/SP - 16-Bit 32MHz XLP MCU | Microchip
N.º da peça: PIC24F16KM102-E/SP ✓ AtivoPIC24F16KM102-E/SP Visão geral
A microcontroller is a semiconductor device that integrates a processor core, nonvolatile program memory, data memory, input/output ports, timers, communication peripherals, and control logic on one integrated circuit. The PIC24F16KM102 belongs to the PIC24F family and uses the PIC24 architecture, which provides a 16-bit instruction set and Harvard-style program and data memory organization. Its compact 28-pin package simplifies prototyping and human-readable breadboard or through-hole assembly.
The device provides 16 KB of Flash memory organized as 5.5K words by 24 bits and 1 KB of SRAM for working data. Its maximum operating frequency is 32 MHz. Flexible capture, compare, and PWM modules support timing, motor-control, and signal-generation tasks, while the configurable logic cell provides additional programmable digital functions. These resources make the PIC24F16KM102 suitable for local control, measurement, communications, and mixed-signal interface systems.
The PIC24F family is positioned for low-power embedded designs, with nanoWatt XLP technology forming part of the family’s low-power feature set. Low-power behavior is especially useful in battery-powered equipment, portable instruments, environmental monitors, and products that spend significant time in sleep or idle states. Developers can use the on-chip clock, timers, interrupt system, and power-management features to reduce activity when external inputs do not require continuous processing.
Typical uses include compact environmental sensors, industrial control modules, appliance controllers, LED drivers, communication interfaces, and low-cost embedded instruments. The 28-pin SPDIP format is particularly helpful when a product is assembled through wave soldering, automated through-hole insertion, or manual prototyping. Firmware can be organized around the PIC24F peripheral architecture while using the 16 KB Flash region for application code and configuration data.
Designers should verify the exact operating voltage, clock configuration, peripheral availability, and decoupling requirements against the manufacturer datasheet before layout release. A 100 nF decoupling capacitor should be placed close to each supply connection, and programming and configuration pins must be routed for ISP or equivalent programming access. The 32 MHz maximum clock speed also requires disciplined clock, layout, and signal-integrity decisions when operated near the upper frequency limit.
This product page combines the exact device identity, package details, technical specifications, design guidance, qualification considerations, and same-footprint alternatives needed to plan an embedded-control design. It also distinguishes the extended-temperature -E grade from the industrial -I grade and clarifies where temperature or qualification requirements determine the correct device ordering code.

Aplicações típicas
PIC24F16KM102-E/SP é adequado para 6 aplicaçãos: Environmental Monitoring, Industrial Control Module, LED Lighting Controller, Motor and PWM Control, Low-Power Sensor Node, Communication Interface Module.
Environmental Monitoring
PIC24F16KM102-E/SP suits compact environmental monitors because its 16-bit PIC24F core operates at up to 32 MHz while providing 16 KB Flash and 1 KB SRAM for acquisition logic, filtering, and data formatting. The configurable logic cell can assist with simple digital conditioning, and the flexible timer peripherals support periodic sampling and sensor timing. At 3.3 V nominal supply, it can manage low-power sensing nodes, provided the individual analog front end and sensors also support that rail. The 28-pin SPDIP package simplifies prototype assembly and socket-based serviceability.
Recomendado
Industrial Control Module
PIC24F16KM102-E/SP provides a compact control core for industrial modules requiring deterministic timing and modest embedded processing. Its flexible capture, compare, and PWM modules can generate or measure control signals, while the 32 MHz CPU handles state machines, communications, and supervisory logic. The extended -40 °C to +125 °C ambient rating supports harsh enclosure environments when the complete assembly also meets its own thermal requirements. The 28-pin SPDIP format is useful during controller development and for low-volume through-hole assembly.
Recomendado
LED Lighting Controller
PIC24F16KM102-E/SP is well matched to LED lighting controllers because its flexible PWM resources can dim multiple channels while the 16-bit CPU manages schedules, current-mode feedback, fault flags, and communications. The 16 KB Flash provides room for a production firmware image, and the 1 KB SRAM supports intermediate control state. At a nominal 3.3 V supply, the MCU can control low-voltage logic while a separate driver stage handles the LED power path. Confirm PWM frequency, duty-cycle resolution, and channel sharing in the device documentation.
Recomendado
Motor and PWM Control
PIC24F16KM102-E/SP can serve as the supervisory controller in a small motor or actuator system, using its 32 MHz processing capability for control loops and its capture, compare, and PWM peripherals for timing functions. The device can decode position inputs, calculate operating states, and supervise protection signals while an external bridge handles motor power. Its 28-pin SPDIP package allows straightforward prototyping before a smaller production package is selected. Validate pulse-width resolution, timer resources, current limits, and thermal margins against the specific motor and driver design.
Recomendado
Low-Power Sensor Node
PIC24F16KM102-E/SP fits low-power sensor nodes that require more control capability than a basic logic device but need compact memory and a simple package. The PIC24F XLP architecture supports power-conscious operation, while the 32 MHz processor can service interrupts, filter measurements, and format results without a large external processor. A 3.3 V nominal rail simplifies integration with low-voltage sensors and radio modules. Battery-life calculations should include radio activity, sensor duty cycle, regulator quiescent current, and the MCU’s configured sleep behavior.
Recomendado
Communication Interface Module
PIC24F16KM102-E/SP can act as the protocol and supervisory controller in a small communication interface. Its 16-bit architecture and 32 MHz operating speed provide adequate headroom for framing, checksums, buffering, and status handling, while the timer peripherals support precise data-transfer timing. The 1 KB SRAM is suitable for short frame buffers and protocol state, although larger transfer workloads may require an external buffer. The 28-pin SPDIP package is convenient for gateway prototypes and proof-of-concept boards before migrating to a smaller production package.

Notas de projeto
Place the required supply-decoupling capacitor directly beside each power pin and provide a short, low-impedance return path to ground. The 28-pin SPDIP footprint should follow the manufacturer package drawing, including the 7.62 mm lead pitch and pin-1 orientation. Keep programming-test pads or connector access available for ISP programming, and avoid routing high-current or high-voltage switching paths between MCU pins to reduce coupling into sensitive timing and communication circuits.
Design the 3.3 V supply for the MCU and all attached peripherals, including startup current, I/O loading, and the load presented by external programming equipment. Confirm the exact voltage limits for this ordering code in the manufacturer electrical-characteristics table. Place bulk and local decoupling according to the application circuit, use a regulator with suitable transient response, and avoid long supply traces between the source and device. Separate analog and digital return paths where the board layout permits it.
Do not approve a replacement solely because it has a 28-pin SPDIP outline. Compare the pin-description table, oscillator options, programming pins, peripheral mapping, interrupt behavior, and configuration bits between the original and proposed device. Temperature-grade and family-designation changes can affect qualification even when the processor, Flash, and SRAM ratings appear identical. Run device-identification and boundary-condition tests on prototypes before using a substitute in production.
Treat every connected output as a switching edge and every input as a possible noise source. Keep oscillator and high-frequency communication traces short, provide a continuous ground reference, and avoid routing them beneath noisy power stages. If the MCU operates near its 32 MHz maximum, verify clock rise time, load capacitance, grounding, and peripheral timing in the final layout. A stable clock is especially important because timer accuracy, PWM behavior, and communication timing depend on it.
Informações de conformidade
