PIC24FV08KM102-I/SP - 8KB Flash 16-bit MCU, SPDIP-28 | Microchip
MPN: PIC24FV08KM102-I/SP ✓ Hoạt độngPIC24FV08KM102-I/SP Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), working memory (RAM), and a rich set of peripherals (ADCs, timers, communication interfaces, GPIO) into one device. The PIC24F family extends this with a 16-bit modified Harvard architecture and Microchip's nanoWatt XLP extreme-low-power extensions, positioning these MCUs in the hierarchy: 16-bit MCU -> PIC24F -> low-power MCU -> embedded microcontroller -> semiconductor IC. The "FV" suffix denotes wide-range (2.0V-5.5V) operation, distinguishing these from the standard "F" 3.3V-only variants.
Key features include a 12-bit ADC with up to 500 ksps conversion rate, configurable logic cells (CLC) for hardware glue logic without firmware, multiple Capture/Compare/PWM (MCCP/SCCP) modules, comparators, and 5V-tolerant I/O. The nanoWatt XLP technology delivers sleep currents below 1 µA with retention, making it suitable for battery-powered products.
Typical applications include low-cost 5V sensor nodes, industrial control panels, low-power IoT endpoints, and consumer white goods. The 28-SPDIP package remains preferred for prototyping, educational kits, and through-hole designs.

Ứng dụng tiêu biểu
PIC24FV08KM102-I/SP phù hợp cho 6 Áp dụngs: 5V Sensor Signal Conditioning, Battery-Powered IoT Sensor Node, Industrial Control Panel PLC, Consumer White Goods Control, Educational Development Platform, Automotive Aftermarket Accessory.
5V Sensor Signal Conditioning
The PIC24FV08KM102-I/SP is purpose-built for 5V analog sensor front-ends because its 2.0V-5.5V wide-voltage range eliminates the need for level shifters on ADC inputs reading 5V transducers. The 12-bit ADC at 500 ksps delivers 4096 codes, sufficient for thermocouple conditioning, RTD bridge excitation, and pressure-sensor ratiometric readings with 0.1% resolution. The three on-chip comparators enable hardware-window detection for sensor-alarm thresholds without CPU involvement. CLC cells let designers wire glue logic (peak-detect latches, PWM modulators) directly between peripherals, freeing the 16 MIPS core for higher-level control loops.

Battery-Powered IoT Sensor Node
The nanoWatt XLP technology on the PIC24FV08KM102-I/SP delivers typical sleep currents below 1 µA with full RAM retention, letting a 3V coin cell power multi-year deployments. The 32 MHz core wakes in microseconds to service EUSART or I2C interrupts, perform an ADC conversion on a sensor, transmit via the on-chip UART, and return to sleep. The 1 KB SRAM fits small protocol stacks (Modbus RTU, custom sensor frames) without external memory, and 512 bytes of EEPROM stores calibration constants and network IDs across power cycles. The wide 2.0V-5.5V range also supports energy-harvesting supplies that vary with ambient conditions.

Industrial Control Panel PLC
The PIC24FV08KM102-I/SP is well-suited to industrial control-panel PLCs because its 5V-tolerant I/O directly drives 24V-interface optocouplers through external resistors, and its 12-bit ADC reads 4-20 mA loop currents via sense resistors. CLC cells can implement hardware interlocks between limit-switch inputs and PWM outputs without software latency. The MCCP/SCCP peripherals generate precise PWM for valve actuators and triac-fired heater control. The SPDIP-28 package simplifies through-hole prototyping on bench-test panels and is preferred by maintenance crews for field-replaceable designs in factory-automation cabinets.

Consumer White Goods Control
For white-goods appliances (washing machines, dishwashers, refrigerators), the PIC24FV08KM102-I/SP delivers the right mix of 5V I/O, 12-bit ADC, and CLC-based hardware logic at low unit cost. The PIC24F core runs motor-control firmware via MCCP/SCCP modules, while the comparators sense zero-crossing on AC mains for triac timing. EEPROM stores user preferences and cycle counters, surviving power cycles. The SPDIP-28 footprint remains common in cost-driven appliance designs because it simplifies manual rework on production lines and field-repair scenarios.

Educational Development Platform
The PIC24FV08KM102-I/SP is a popular choice for university microcontroller courses and hobby kits because the SPDIP-28 package fits a standard 0.6 inch wide DIP socket, allowing students to insert and remove the MCU without soldering. The 16-bit PIC24F architecture offers a meaningful step up from PIC16 in instruction set complexity while remaining simpler than ARM Cortex-M. MPLAB X IDE with the XC16 compiler and the PICkit 4 programmer provide a free toolchain. The 8 KB Flash accommodates realistic capstone firmware projects, and CLC cells teach digital-logic concepts through hardware configuration.
Được đề xuất
Automotive Aftermarket Accessory
The PIC24FV08KM102-I/SP can power non-safety automotive aftermarket accessories such as interior lighting controllers, aftermarket gauge clusters, and alarm-system keypads, but is not AEC-Q100 qualified and should not be used in safety-critical vehicle functions. The wide 2.0V-5.5V range tolerates the 12V automotive rail after external regulator reduction. The 12-bit ADC reads automotive sensor outputs (oil-pressure senders, thermistor temperature probes), and the comparators implement window-watchdog supervision on the supply rail. For AEC-Q100 qualified automotive designs, choose PIC24F equivalents from the KA or FJ automotive families.

Ghi chú thiết kế
Decouple VDD (pin 20) with a 100 nF ceramic capacitor placed within 5 mm of the pin, plus a bulk 10 µF tantalum or aluminum polymer capacitor on the same rail. The PIC24FV08KM102-I/SP draws up to 25 mA at 32 MHz / 5V, so the regulator must source at least 50 mA to handle transient peaks. Place a ferrite bead in series with VDD if the board shares a noisy rail with relays or motors.
Keep the crystal traces (OSCI/CLKI and OSCO/CLKO) short and symmetric, surrounded by a grounded guard ring to reduce EMI pickup. The ICSP pins (PGC and PGD on RB6/RB7) must remain accessible for in-circuit programming; do not load them with > 5 kΩ of resistance or strong pull-ups that prevent the programmer from driving them. Route the analog ADC inputs away from digital switching traces to preserve 12-bit conversion accuracy.
Avoid confusing the PIC24FV08KM102 (2.0V-5.5V wide-voltage) with the PIC24F08KM102 (3.0V-3.6V only). The FV part is the correct choice for 5V analog designs. Do not pull MCLR high through more than 10 kΩ or the brown-out reset may not trigger reliably below 2.0V. When migrating firmware between KM102 and KM202 variants, verify the interrupt vector table because the on-chip peripherals differ between the two dies.
