PIC24F16KM102-I/SP - 16KB Flash 32MHz 16-bit XLP MCU | Microchip
MPN: PIC24F16KM102-I/SP ✓ AktifPIC24F16KM102-I/SP Ringkasan
What is a PIC24F microcontroller? PIC24F is Microchip's 16-bit Modified-Harvard MCU architecture - the mid-range step between the 8-bit PIC16/PIC18 and the 32-bit PIC32. PIC24F devices use a 24-bit instruction word with 16-bit data paths, offer far richer peripherals than PIC16/PIC18 while consuming less power and costing less than PIC32. The 'F' suffix indicates Flash program memory. PIC24F sits in the taxonomy: PIC24F -> 16-bit MCU -> microcontroller -> embedded IC -> semiconductor.
Key features of the PIC24F16KM102-I/SP include nanoWatt XLP deep-sleep modes that drop current to the sub-microamp range, a 12-bit A/D converter with up to 9 channels, multiple 16-bit timers, a Real-Time Clock and Calendar (RTCC) module, and on-chip CLC that lets designers wire internal peripherals into custom combinational/sequential logic without external gates. The device supports 24 I/O pins across its 28-pin SPDIP body, giving ample headroom for sensor and user-interface integration.
Architecturally, the PIC24F16KM102 pairs a modified-Harvard CPU with single-cycle 16-bit ALU operations, hardware Multiply and Divide, and an interrupt controller that supports both fixed and programmable priority levels. The wide 1.8V to 5.5V operating range means the same part can power directly from a single Li-ion cell, two alkaline cells, a 3.3V LDO output, or a regulated 5V rail - eliminating a level-shifter stage in mixed-voltage designs.
Typical applications include battery-powered IoT sensor nodes, consumer appliances, low-cost motor and lighting controllers, USB-CDC serial bridges, and industrial control modules. In each, the XLP sleep currents below 1 uA extend battery life, while the CLC and PWM simplify BOM by removing discrete gates and timer ICs.
Design consideration: when migrating from PIC24F16KA102 designs, verify peripheral remapping and CLC pin assignments - although both are XLP PIC24F parts, the KM family expands logic-cell and PWM resources.

Aplikasi Umum
PIC24F16KM102-I/SP cocok untuk 7 aplikasis: Battery-Powered IoT Sensor Nodes, Consumer Appliance Control, Low-Cost Motor and Lighting PWM Controllers, USB-CDC Serial Bridge / Debug Companion, Industrial Control and Sensor Modules, Wearable and Portable Health Devices, Educational and Hobby Electronics (Arduino-class).
Battery-Powered IoT Sensor Nodes
The PIC24F16KM102-I/SP is well suited to coin-cell and 2x AA battery IoT sensor nodes because nanoWatt XLP technology drops deep-sleep current below 1 uA per the Microchip datasheet, extending multi-year battery life. With 16 KB Flash, 2 KB SRAM and 12-bit ADC, the MCU can locally buffer sensor readings before waking on a CLC-configured interrupt to transmit over UART or SPI. Wide 1.8-5.5 V operation lets it run directly from the battery without an LDO stage, and the CLC block allows hardware-only event detection without CPU wake.

Consumer Appliance Control
In consumer appliances such as coffee machines, air purifiers and small kitchen tools, the PIC24F16KM102-I/SP delivers ample 32 MHz performance for user-interface and sensor-fusion tasks while consuming only microamps in standby. The 24 GPIO handle keypad scanning, LED PWM dimming via CCP modules, and rotary-encoder inputs without external logic. Its 1.8-5.5 V range supports both 3 V battery backup and 5 V mains-powered designs, and the integrated RTCC provides real-time scheduling for delayed-start features without an external RTC chip.

Low-Cost Motor and Lighting PWM Controllers
The PIC24F16KM102-I/SP drives low-power BLDC, stepper and DC motors through its 16-bit PWM and CCP modules, with the CLC block implementing hardware commutation logic that offloads the CPU. For LED lighting strips, multiple CCP outputs provide per-channel dimming at frequencies that avoid visible flicker, while 12-bit ADC reads feedback from current-sense amplifiers for closed-loop brightness control. The MCU's nanoWatt XLP sleep modes suit always-listening lighting controllers that wake only on user input.

USB-CDC Serial Bridge / Debug Companion
As a USB-to-UART or USB-to-SPI bridge, the PIC24F16KM102-I/SP pairs with an external USB PHY or uses bit-banged software USB on lower-speed endpoints, exposing legacy serial buses to PCs. With 16 KB Flash, designers can fit CDC, vendor-class and HID stacks from Microchip's MLA library, while 2 KB SRAM buffers bulk transfers. The 32 MHz core keeps enumeration and bulk throughput responsive, and the wide supply range simplifies bus-powered designs.

Industrial Control and Sensor Modules
In industrial sensor modules and small PLCs, the PIC24F16KM102-I/SP offers 12-bit ADC accuracy and wide operating temperature (-40 C to +85 C industrial) needed for factory environments. The CLC enables hardware-level safety interlocks that react in single clock cycles - faster than software loops - while the RTCC timestamps events with on-chip calendar registers. UART/SPI/I2C connect to field-bus transceivers or local HMI displays, and 1.8-5.5 V tolerance eases 24 V-bus powered designs via a small LDO.

Wearable and Portable Health Devices
Wearable health and fitness devices benefit from the PIC24F16KM102-I/SP's XLP deep-sleep currents below 1 uA, allowing weeks of battery life on small Li-ion cells. The 12-bit ADC reads heart-rate, SpO2 and motion sensors, while the RTCC provides timestamps for activity logs without an external RTC. CLC implements step-counter logic from accelerometer interrupts without CPU wake, and the 28-SPDIP footprint is useful for development boards even when production moves to QFN variants like PIC24F16KM102-I/ML.

Educational and Hobby Electronics (Arduino-class)
The PIC24F16KM102-I/SP is popular in education because the 28-SPDIP through-hole package plugs directly into breadboards, with all I/O accessible without fine-pitch soldering. MPLAB X IDE plus the XC16 compiler and the MPLAB Snap debugger form a free toolchain, and Microchip's Code Examples cover ADC, PWM, I2C and UART projects. With 32 MHz and 16 MIPS the chip is fast enough for signal-processing experiments, while still consuming only microamps - ideal for teaching low-power design.

Catatan Desain
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin (pin 20) and a bulk 10 uF tantalum or ceramic at the board supply input. The PIC24F16KM102's 1.8-5.5 V range allows direct battery connection, but adding a ferrite bead plus bulk cap reduces VDD droop during PWM transitions. Estimated: at 32 MHz the core draws ~15 mA at 3.3 V, so a low-ESR 10 uF cap is sufficient for transient loads.
Keep the MCLR pull-up (typically 10 kohm to VDD) close to pin 1 to ensure clean reset behaviour, and place the ICSP PGD/PGC lines (RB6/RB7) away from switching signals to avoid debugger noise. The 28-SPDIP through-hole footprint simplifies breadboard prototyping but in production prefer the SOIC-28 (PIC24F16KM102-I/SO) for SMT assembly.
Do not leave the MCLR pin floating - it must be tied high through a resistor or directly to VDD. The CONFIG words must be set correctly to enable the internal oscillator; without proper configuration the device may appear 'dead' even though VDD is present. Estimated: the 16-bit configuration registers contain watchdog, code-protect and oscillator settings that are read at every reset.
When using the ADC, add a small RC filter (100 ohm + 100 nF) on the analog input to suppress switching noise from PWM outputs. The 12-bit ADC achieves best linearity with an input impedance under 2 kohm, so use a rail-to-rail op-amp buffer (e.g., MCP6002) for high-impedance sensor sources.
