PIC24FV08KM101-I/SS Übersicht
A 16-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and a rich set of peripherals (ADC, timers, communication ports) into one package. 16-bit MCUs such as the PIC24F family sit between 8-bit microcontrollers and 32-bit ARM Cortex-M parts, offering higher computational throughput (16 MIPS at 32 MHz) than 8-bit parts while keeping cost, code complexity, and power consumption well below typical 32-bit alternatives. The 'F' in PIC24F denotes the Flash-based, low-power product line, and the 'FV' extension indicates the wide-voltage variant supporting 2.0V to 5.5V.
Key features include XLP™ nanoWatt technology with multiple low-power modes (Sleep, Idle, Doze), an integrated 12-bit A/D converter, configurable logic cells that let designers replace discrete glue logic with on-chip peripherals, and peripheral pin select for flexible signal routing. The device also includes a real-time clock calendar (RTCC) and a charge time measurement unit (CTMU) for capacitive touch and basic sensor interfaces.
Architecturally, the PIC24FV08KM101 uses a 16-bit modified Harvard core with separate instruction and data paths, a hardware stack, and 16 working registers, achieving 16 MIPS at 32 MHz. The 8KB Flash holds approximately 2.75K 24-bit instructions, and the 1KB data RAM supports C-language stacks and buffers. Wide-voltage operation is achieved through an on-chip voltage regulator that derives the internal 1.8V logic supply from the wide VIN range.
Typical applications include low-power sensor nodes, battery-powered portable instruments, home appliances, LED lighting control, capacitive touch user interfaces, and small industrial control modules where 8-bit performance is insufficient but cost and power must remain low.
When designing with this MCU, verify that the application fits within 8KB of Flash and 1KB of RAM, and choose the appropriate clock configuration (internal 8 MHz FRC or external crystal) to balance power consumption against timing accuracy. The SSOP-20 footprint is hand-solderable but uses a 0.65 mm pitch, so production boards typically reflow.

Typische Anwendungen
PIC24FV08KM101-I/SS ist geeignet für 6 Anwendungs: Battery-Powered Sensor Node, Capacitive Touch User Interface, Home Appliance Control Board, LED Lighting Controller, Portable Medical Monitoring Device, Small Industrial Control Module.
Battery-Powered Sensor Node
The PIC24FV08KM101-I/SS is engineered for low-power wireless sensor nodes where wide-voltage battery support and nanoWatt XLP modes are essential. Its 2.0V to 5.5V supply range lets a single design operate from a fresh 3V coin cell down to a depleted 2V alkaline stack without a boost converter. In Sleep mode the device draws microamp-level current, waking on interrupts from the ADC, CTMU, or RTCC for periodic measurements. The 12-bit ADC and integrated CTMU provide direct capacitive or resistive sensor interfaces without external analog front-end ICs, reducing BOM cost. With 8KB Flash and 1KB RAM, the part comfortably fits typical sensor-fusion plus LoRa/BLE stack-lite firmware.
Empfohlen
Capacitive Touch User Interface
The PIC24FV08KM101-I/SS is well suited to capacitive touch keypads and sliders because it integrates a Charge Time Measurement Unit (CTMU) that measures capacitance with sub-pF resolution. Combined with Configurable Logic Cells (CLC), designers replace external gates and timers with on-chip logic, shrinking the PCB and BOM. The 17 I/O pins support up to 12 self-capacitance touch channels plus indicator LEDs and a UART bridge to a host MCU. XLP Sleep mode keeps idle current in the microamp range, critical for battery-powered remote controls. The 32 MHz CPU executes touch-decimation and debounce firmware with ample headroom within the 8KB Flash budget.
Empfohlen
Home Appliance Control Board
The PIC24FV08KM101-I/SS fits small home appliances such as coffee machines, blenders, and smart plugs where the MCU must read sensors, drive TRIACs or relays, and display status on a small LED array. The 2.0V to 5.5V supply accommodates universal 5V/3.3V peripheral rails, and the integrated 12-bit ADC handles thermistor, voltage, and current sensing. Capture/Compare/PWM modules generate the timing for power-factor control and TRIAC firing. Industrial -40C to +85C temperature grade supports unheated enclosures. Wide availability from multiple distributors simplifies long-life appliance production runs that span many years.
Empfohlen
LED Lighting Controller
The PIC24FV08KM101-I/SS serves as a low-cost controller for dimmable LED drivers and color-mixing fixtures. Its Capture/Compare/PWM peripherals generate the high-resolution PWM required for smooth 16-bit dimming without flicker, and the CLC blocks implement safety interlocks and zero-cross detection without external logic. Wide 2.0V to 5.5V supply lets the same firmware run on 3.3V or 5V LED driver boards. The RTCC schedules daylight-saving transitions and ambient-light ramp curves in connected luminaires. Industrial temperature grade plus XLP Sleep modes support always-on standby with under-100uA quiescent draw.
Empfohlen
Portable Medical Monitoring Device
The PIC24FV08KM101-I/SS fits portable medical peripherals such as pulse oximeters, spirometers, and digital thermometers where low power, small package, and analog integration are paramount. The 12-bit ADC plus op-amp peripherals built into the PIC24F KM family enable direct photodiode or thermistor signal conditioning, while the CTMU simplifies flow-sensor capacitance measurement. Wide 2.0V to 5.5V operation supports both Li-ion and 2xAA chemistries through the same firmware. The -40C to +85C industrial temperature rating accommodates refrigerated storage and clinical environments. Designers transitioning to FDA-class designs should move to the AEC-Q100 qualified variants.
Empfohlen
Small Industrial Control Module
The PIC24FV08KM101-I/SS is a strong fit for compact industrial modules such as sensor transmitters, valve controllers, and small motor drivers that need deterministic 16-bit performance without the cost of a 32-bit MCU. Its CCP modules interface to quadrature encoders and PWM-driven half-bridges, while the UART/I2C/SPI peripherals link to industrial transceivers like RS-485 or CAN bridges. Wide-voltage operation tolerates long cable drops in 24V industrial rails after regulation down to 5V or 3V. The CLC blocks implement safety logic such as watchdog and interlocks directly on the MCU, removing external PLDs.

Wichtigste Unterscheidungsmerkmale
- Wide 2.0 V to 5.5 V operating voltage, supporting both 3.3 V and 5 V rails without a regulator swap (vs. PIC24F08KM101-I/SS (F variant))
- Integrated Configurable Logic Cells (CLC) and CTMU on-chip, reducing external glue logic (vs. PIC24FJ64GA002)
- Lowest-cost 16-bit MCU with nanoWatt XLP Sleep mode under typical 100 uA (vs. PIC24FV16KM101-I/SS)
- Single-chip analog-rich MCU integrating ADC, op amps, and CTMU (vs. Discrete MCU plus external analog front-end ICs)
Designhinweise
Estimated: when the PIC24FV08KM101-I/SS runs at 32 MHz from a 3.3 V supply and all 17 I/O pins are unloaded, the core draws approximately 12 mA. Add decoupling per the Microchip datasheet recommendation: a 0.1 uF ceramic capacitor on each VDD pin (pins 1 and 20) placed within 3 mm of the package, plus a bulk 10 uF tantalum or ceramic at the supply entry. For battery applications, prefer the internal 8 MHz FRC oscillator in Sleep mode to drop current below 100 uA and only switch to 32 MHz PLL for active periods.
Place the SSOP-20 footprint with the Microchip recommended land dimensions (0.45 mm pad length, 0.30 mm width) and use a 0.65 mm pitch. Route the OSC1/OSC2 pins (9 and 10) with short, symmetric traces and a guard ring tied to VSS to minimize EMI pickup. If using the ICSP programming pins (typically PGEDx/PGECx mapped via peripheral pin select), expose them on a 0.1 inch header or test pad for production programming. Keep analog and digital traces separated; the KM family has separate AVSS/AVDD on larger variants but shares rails on SSOP-20.
Estimated: a common mistake is configuring the MCLR pin (RA5) as a regular I/O without disabling the MCLR function via the Configuration bit FWDTEN or appropriate CONFIG register, causing the MCU to remain in Reset. Another pitfall is assuming the PIC24FV08KM101 (FV, wide voltage) and PIC24F08KM101 (F, narrow voltage) are interchangeable in 5V designs - the F variant VIN max is 3.6V and will fail in 5V systems. Always verify Configuration bits in code before mass production to lock oscillator and watchdog settings.
For SSOP-20 hand prototyping and rework, expose a 0.1 inch dual-header footprint under the SSOP pads so you can plug in a TQFP-to-DIP adapter board - this avoids damaging the fine-pitch SSOP during repeated programming cycles. Production boards should use ENIG finish to preserve solderability over the long lifecycle typical of Microchip 16-bit MCU designs.
