PIC24F16KM102T-I/SO Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of on-chip peripherals such as timers, ADC, communication interfaces and configurable logic. The PIC24F family is built around Microchip's 16-bit modified Harvard architecture, sitting in the hierarchy between 8-bit PIC MCUs and the higher-end dsPIC/PIC 32 families. The XLP designation indicates aggressive nanoWatt sleep-current design, making KM1-series parts especially well-suited to battery-powered or energy-harvesting products.
Key features of the PIC24F16KM102T-I/SO include 16 KB Flash (5.5 K × 24 instruction words), 1 KB RAM and 512 bytes of EEPROM, three 16-bit Capture/Compare/PWM (MCCP/SCCP) modules, a 12-bit A/D converter with up to 10 channels, analog comparators, a Configurable Logic Cell (CLC) for hardware glue logic, and a rich set of serial peripherals including I²C, SPI and UART. The wide 1.8 V to 5.5 V operating voltage range plus a low-power sleep current in the microamp range positions this part for portable, sensor and consumer devices.
The architecture combines a 16-bit data path with an 8-channel DMA, dual 16-bit timers and a flexible pin-mapping Peripheral Pin Select (PPS) block. PPS allows digital peripherals to be remapped to a wide range of I/O pins at runtime, which simplifies PCB layout and BOM reuse inside the KM1 family. The 12-bit ADC supports up to 500 ksps with hardware accumulation, and the CLC block can implement state machines, waveform generation and signal conditioning in pure hardware.
Typical applications include ultra-low-power sensor nodes, battery-powered IoT endpoints, portable medical accessories, consumer human-interface devices, low-cost motor control, and general-purpose embedded control with a 3 V coin-cell or USB-derived supply. The 28-pin SOIC package also enables hand-soldering and breadboarding for prototype and hobby use. Compared with smaller 14/20-pin KM1 devices, the 28-pin variants expose more ADC channels and PWM channels, so they fit designs where more analog or timing resources are required.
When designing with this part, budget for an external decoupling network of 100 nF + 10 µF within 5 mm of every VDD/VSS pair, and use the PPS block to keep high-speed signals short. The KM1 family shares its MPLAB X IDE toolchain, MCC code configurator and XC16 compiler with other PIC24F devices, easing migration if a 28-pin part becomes capacity-constrained and you move up or down the family.

Design Notes
Estimated: power dissipation at 32 MHz active mode with VDD = 3.3 V is typically 15 mW, dropping to microamps in XLP sleep mode. Decouple every VDD/VSS pair with 100 nF X7R within 5 mm of the pin, plus a shared 10 µF bulk capacitor on the main supply rail. For battery-powered designs, route XLP-active power pins in the order described in the datasheet (AVDD before VDD) to avoid inrush current on wake-up events that can brown out coin cells.
The 28-SOIC wide-body package has a theta-JA around 50-100 °C/W. At maximum active current 15 mW, junction-temperature rise above ambient is under 1 °C. For continuous 32 MHz operation at 125 °C ambient, ensure the PCB has at least 1 square inch of copper pour connected to the VSS pin. Industrial-grade silicon (the 'I' suffix) guarantees operation from -40 °C to +85 °C without thermal derating; the 'E' suffix is rated -40 °C to +125 °C for harsh-environment designs.
Place the 28-SOIC package with a 1.27 mm (50 mil) pin pitch, leaving 0.5 mm clearance between adjacent pins and traces for hand-soldering rework. Route the crystal traces (OSC1/OSC2) as short as possible, surrounded by a ground pour, and keep high-speed digital signals away from the analog AVSS/AVDD pair. Use the PPS (Peripheral Pin Select) block to remap functions to quiet pins at runtime, simplifying PCB layout for noise-sensitive analog measurements.
Do not exceed the maximum VDD of 5.5 V. Always configure the unused I/O pins as outputs (not inputs) to avoid supply-current shoot-through faults. The MCLR pin requires an external 10 kΩ pull-up to VDD if not used; omitting this prevents programming via ICSP. The PIC24F versions are not 5 V tolerant on digital I/O; use the PIC24FJ or PIC24FV variants if you need true 5 V I/O tolerance. Source: Microchip PIC24F16KM102 datasheet, Section 'Electrical Characteristics'.
Keep ADC analog traces (AN0..AN9) at least 3 mm away from PWM or digital switching traces to avoid coupled noise. Use a star-ground topology with separate analog and digital ground planes joined only at the MCU VSS pin. Place the 100 nF + 10 µF decoupling network within 5 mm of the AVSS/AVDD pair, and add a ferrite bead if the analog and digital supplies are not isolated.
