PIC24F08KA102-I/SS Übersicht
A microcontroller (MCU) is a single-chip computer that contains a processor core, program and data memory, and programmable I/O peripherals. The PIC24F family represents Microchip's 16-bit modified Harvard architecture, sitting between the 8-bit PIC18 and the 32-bit PIC32 families. Within the power-management IC hierarchy, low-power MCUs such as the PIC24F08KA102 enable battery-powered and energy-harvesting systems by minimizing quiescent current.
Key features of the PIC24F08KA102-I/SS include a 16-channel 10-bit ADC, five 16-bit timers, four PWM outputs, two I2C, two SPI, and two UART interfaces, plus an RTCC, a comparator, and a charge time measurement unit (CTMU). The device operates from 1.8 V to 3.6 V and provides 24 general-purpose I/O pins with interrupt-on-change capability. The XLP peripherals - deep sleep brown-out reset (DSBOR), deep sleep watchdog timer (DSWDT), and real-time clock calendar (RTCC) - keep the chip alive in sleep while consuming nanoamp currents.
The PIC24F08KA102 family is built on a CMOS process with an internal 8 MHz RC oscillator that supports PLL multiplication up to 32 MHz. The modified Harvard architecture separates program and data buses, allowing simultaneous instruction fetch and data access, which simplifies compiler code generation while preserving deterministic interrupt latency for real-time control.
Typical applications include battery-powered IoT sensor nodes, wearable health monitors, automotive body controllers, and industrial metering equipment. The combination of 16 MIPS throughput, multiple serial interfaces, and nanoWatt XLP sleep modes suits applications where duty-cycled compute and multi-year battery life are required.
When designing with this device, ensure the VDD supply is decoupled with 100 nF ceramic capacitors placed within 3 mm of the package pins. The internal 8 MHz fast RC oscillator provides adequate accuracy for UART communication at 32 MHz; an external crystal should be added only when USB-style timing precision is required. The MCLR pin must be pulled high through a 10 kohm resistor unless the internal MCLR is selected in the configuration bits.

Typische Anwendungen
PIC24F08KA102-I/SS ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Nodes, Wearable Health Monitoring Devices, Automotive Body and Comfort Electronics, Industrial Metering and Data Loggers, Remote Controls and Human Interface Devices, Portable Test and Measurement Instruments.
Battery-Powered IoT Sensor Nodes
The PIC24F08KA102-I/SS suits coin-cell IoT sensor nodes because its nanoWatt XLP deep-sleep mode draws under 20 nA while retaining 1.5 KB SRAM and the RTCC, allowing multi-year battery life with periodic wake-and-transmit duty cycles. Its 32 MHz/16 MIPS throughput handles on-sensor edge filtering before low-power radio transmission. The 8 KB Flash accommodates BLE stack fragments or LoRaWAN MAC code, and the 16-channel 10-bit ADC reads temperature, humidity, and battery voltage directly. Combined with two UARTs for sensor radios, two I2C/SPI for digital sensors, and 1.8-3.6 V operation, this part is a strong fit for wireless sensor nodes deployed at scale.

Wearable Health Monitoring Devices
Wearables for heart-rate, SpO2, and step monitoring require the lowest possible sleep current to extend coin-cell life to weeks or months. The PIC24F08KA102-I/SS delivers nanoWatt XLP deep-sleep currents with the RTCC running, allowing scheduled sensor sampling at 1 Hz with negligible battery drain. The 10-bit ADC captures photodiode outputs from pulse oximeters, while two I2C buses interface with accelerometers and optical sensors. The 24 GPIO pins support LED indicators, haptic feedback drivers, and capacitive touch buttons, and the 1.8 V minimum VDD supports direct Li-ion or 2x alkaline cell operation. SSOP-28 is small enough for wristband PCBs.

Automotive Body and Comfort Electronics
The PIC24F08KA102-I/SS is AEC-Q100 qualified and operates from -40C to +85C industrial / up to +125C extended, suiting automotive body controllers for door modules, seat controls, mirror adjusters, and interior lighting. The PIC24F core's deterministic interrupt latency suits CAN-style LIN bus gateways via UART, while 4 PWM channels drive LED dimming and small brushed motors. Its 24 I/O pins connect to Hall sensors, switches, and relay drivers, and the 1.8-3.6 V operation matches 3.3 V regulated automotive rails. The 8 KB Flash supports local LIN slaves with diagnostic services.
Empfohlen
Industrial Metering and Data Loggers
Industrial meters for water, gas, and energy require robust low-power MCUs with analog front-ends and serial connectivity. The PIC24F08KA102-I/SS integrates a 10-bit ADC with up to 16 channels for direct transducer readout, while the comparator enables threshold-based metering without waking the CPU. The 512-byte EEPROM stores calibration constants and tamper logs without external storage. RTCC with deep-sleep retention timestamps events even when the main core is off, and the 8 KB Flash hosts metering algorithms and Modbus or wireless M-Bus stacks.
Empfohlen
Remote Controls and Human Interface Devices
Battery-powered remote controls for TVs, smart-home hubs, and industrial HMIs benefit from the PIC24F08KA102-I/SS's deep sleep nanoamp currents combined with interrupt-on-change GPIO that wakes the MCU from any button press. The 24 GPIO pins scan a 6x4 keypad matrix directly without external drivers, and the UART or SPI connects to 2.4 GHz radios or IR transmitters. The 32 MHz/16 MIPS core drives LCD segment displays via software, eliminating dedicated display controllers. The 1.8 V minimum VDD supports two AAA cells across their full discharge curve.
Empfohlen
Portable Test and Measurement Instruments
Handheld multimeters, insulation testers, and clamp meters benefit from the PIC24F08KA102-I/SS's 16 MIPS compute throughput for real-time RMS calculation, plus its 10-bit ADC with up to 16 channels for voltage and current sensing. The 4 PWM outputs generate audible beeps and tone bursts for continuity testing, and the 1.5 KB SRAM buffers sampled waveforms before display update. The AEC-Q100 qualification provides ESD and temperature robustness required for field instruments. The SSOP-28 package fits compact handheld enclosures with minimal PCB area.

Designhinweise
Decouple VDD with at least one 100 nF ceramic capacitor placed within 3 mm of the pin 27 supply pad, plus a bulk 1 uF to 10 uF capacitor on the same rail. For deep sleep nanoWatt XLP operation, disable unused peripherals via the PMD register and configure IOC on a single wake-up pin. Estimated idle current at 3.3 V with RTCC running and CPU off is under 1 uA, but proper decoupling reduces peak current transients during wake-up that can otherwise cause spurious resets on weak battery sources.
Route the SSOP-28 footprint with a 0.65 mm pitch land pattern and 0.4 mm wide traces. Place the MCLR pull-up (typically 10 kohm to VDD) directly adjacent to pin 28 to avoid capacitive coupling that could cause spurious resets. Keep the oscillator traces (RA6/OSC2 and RA7/OSC1) short and surrounded by a grounded guard ring when using an external crystal to avoid radiated EMI from the 32 MHz fundamental and harmonics.
Ensure configuration bits select the internal FRC oscillator with PLL for 32 MHz operation unless an external crystal is fitted; otherwise the device will boot at 8 MHz and peripherals like UART will calculate wrong baud rates. The MCLR pin must never be left floating - either tie it to VDD through a resistor or disable external MCLR in the configuration register. For programming/debugging via ICSP, reserve pins RB0/PGED1 and RB1/PGEC1 as the dedicated programming pair and never repurpose them as outputs in production firmware.
