PIC24F16KM102-I/SS 개요
A 16-bit microcontroller (MCU) is a single-chip computer with a 16-bit datapath, program counter and ALU, positioned between 8-bit MCUs and 32-bit MCUs in the embedded hierarchy: 16-bit MCU -> microcontroller -> embedded processor -> semiconductor. The PIC24F family belongs to the nanoWatt XLP eXtreme Low Power family and is widely used in cost-sensitive, low-pin-count, battery-powered designs that need higher arithmetic performance than 8-bit parts without the cost of a 32-bit ARM core.
Key features include 24 general-purpose I/O pins, brown-out reset, low-voltage detect, power-on reset, watchdog timer, PWM output, and a peripheral pin select (PPS) mapping engine. The on-chip Configurable Logic Cell lets designers implement glue-logic, waveform synthesis or simple state machines in hardware without external gates, reducing BOM cost and PCB area.
The device uses a modified Harvard architecture with separate program Flash and data EEPROM/RAM buses, allowing concurrent instruction fetch and data access for deterministic 32 MHz performance. PPS routing of digital peripherals to physical pins gives layout flexibility, while the 12-bit ADC can be paired with the CLC for sensor-edge processing.
Typical applications include consumer white goods, low-cost sensor nodes, building automation, portable instrumentation, and USB/HID-free human-interface boards. The wide operating voltage also makes it suitable for industrial 24 V-bus-derived rails after pre-regulation. Compared to PIC24F16KA102-I/SS, this KM102 variant adds configurable logic cells and more flexible timer options, while sharing the same Flash and RAM density for direct migration.
When designing with this part, allocate decoupling of 100 nF plus 10 uF bulk close to VDD/VSS, keep ADC traces short, and use the PPS feature to remap peripherals instead of re-spinning the PCB. The CLC module must be configured before peripheral disable to avoid transient logic glitches.

일반적인 애플리케이션
PIC24F16KM102-I/SS 적합 용도: 6 애플리케이션s: Consumer White Goods Control Board, Battery-Powered Sensor Node, Industrial Building Automation, Portable Handheld Instrumentation, Automotive Body Electronics (Non-Safety), User Interface / HMI Controller Board.
Consumer White Goods Control Board
The PIC24F16KM102-I/SS fits white-goods control boards because its 1.8-5.5 V supply accepts both 3.3 V and 5 V rails derived from rectified mains, while the 12-bit ADC and 24 GPIO pins handle user-interface buttons, LED indicators, and triac-fired loads. Its 16 KB Flash accommodates state-machine firmware for wash cycles, door-lock interlocks, and sensor multiplexing without external memory, and the CLC peripheral replaces external logic gates for zero-cross detection. Compared with 8-bit PIC16 parts, the 16-bit core executes math faster for motor-control PI loops, and the wide -40C to +85C operating range survives appliance environments.
추천
Battery-Powered Sensor Node
The PIC24F16KM102-I/SS is well-suited for battery-powered sensor nodes thanks to its nanoWatt XLP sleep modes that drop quiescent current into the sub-uA range, preserving coin-cell life for years. The integrated 12-bit ADC reads thermistor, photodiode, or battery-sense signals directly, while the configurable CLC performs edge detection and wake-up without CPU intervention, reducing firmware overhead and energy per measurement. Its 1.8 V minimum supply supports two AA or single Li-ion chemistries, and the small 28-SSOP footprint leaves board space for an RF module or MEMS sensor.
추천
Industrial Building Automation
In building-automation subsystems (HVAC dampers, lighting controllers, occupancy hubs), the PIC24F16KM102-I/SS combines LIN and UART connectivity for field-bus or RS-485 link layers with PWM outputs that drive LED dimmers or proportional valves. The wide 1.8-5.5 V supply simplifies 24 V-bus-derived designs after a small LDO, while 24 GPIO pins handle keypads, relay drivers, and isolated digital inputs. Compared with discrete 8-bit solutions, the 16-bit core plus 16 KB Flash supports BACnet or Modbus stack lite without external program memory, reducing BOM count and BOM cost.
추천
Portable Handheld Instrumentation
The PIC24F16KM102-I/SS drives portable handheld instruments such as digital multimeters, clamp meters, and environmental meters where low power and compact PCB are critical. Its 12-bit ADC delivers sufficient resolution for shunt-based current sensing and thermistor linearization, while the CLC generates reference PWM signals for auto-zeroing. The 32 MHz core executes RMS and averaging math faster than 8-bit MCUs, enabling faster display refresh, and the wide -40C to +85C industrial range survives outdoor use. A 28-SSOP footprint allows single-sided PCB assembly to keep tooling costs low.
추천
Automotive Body Electronics (Non-Safety)
Although the PIC24F16KM102-I/SS is industrial-grade, its LIN/UART peripherals and 1.8-5.5 V supply make it suitable for non-safety automotive body modules such as HVAC panel controllers, mirror adjusters, and seat-heater switches. The wide -40C to +85C range handles cabin environments, while the 16-bit core manages LIN slave protocol stacks without offloading to a transceiver MCU. Designers targeting AEC-Q100 should select PIC24F16KM102-I/SS or move to the KM104 family automotive variants, but the I/SS industrial grade remains a cost-effective choice for aftermarket and non-safety subsystems.
추천
User Interface / HMI Controller Board
The PIC24F16KM102-I/SS is a strong fit for low-cost HMI boards that drive segment LCDs, character displays, or LED matrices where the host processor is already busy. Its 24 GPIO pins multiplex key-scan matrices and LED row/column drivers, while the CLC offloads debouncing and PWM dimming from the CPU. The 16 KB Flash supports small graphics libraries and menu trees, and the 28-SSOP footprint keeps the bill of materials compact for tightly packed front panels. Peripheral pin select lets PCB designers route UART/SPI to any pin, simplifying single-layer layouts.

설계 노트
Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 11) with the ground return via a short trace to VSS (pin 10). Add a 10 uF bulk capacitor near the supply entry point to suppress transient loading during ADC conversions. The wide 1.8 V to 5.5 V supply range means the same part can be powered from a 3.3 V LDO or directly from a 5 V rail, but always verify the brown-out reset voltage matches your brown-out threshold in the configuration bits. Estimated: assuming 32 MHz operation and average 12 mA core current, a 10 uF bulk keeps ripple under 30 mV during ADC bursts.
Keep the analog and digital ground returns separate, joining them at a single star point beneath the MCU to avoid ground-loop noise coupling into the 12-bit ADC. Route the MCLR line (pin 1) with a 10 kohm pull-up to VDD and place the decoupling cap within 5 mm of the pin. The programming pins PGED1 (RB0) and PGEC1 (RB1) should be accessible via test pads or header for in-circuit serial programming (ICSP).
Do not enable the on-chip ADC without first configuring the I/O pins as analog inputs in the TRIS and ANSEL registers; otherwise the digital input buffer fights the analog signal and corrupts ADC readings. When migrating between PIC24F16KM102 and PIC24F16KM202, only Flash size changes - all peripheral registers and pin assignments remain identical, so existing firmware runs unchanged. Estimated: at 32 MHz, each ADC conversion takes approximately 1.6 us with the default Tad, so budget ADC sampling windows carefully when using DMA-style burst reads.
