PIC24FV08KM202-E/SO 概要
A PIC24F microcontroller is a 16-bit RISC processor from Microchip's PIC family, sitting in the hierarchy: microcontroller -> embedded MCU -> 16-bit MCU -> PIC24F series. Compared with 8-bit MCUs, the 16-bit PIC24F core delivers higher MIPS-per-MHz, wider 16-bit data paths, more efficient C-code execution, and richer peripherals, while retaining the PIC ecosystem's MPLAB X toolchain and peripheral library support.
Key features include 8KB Flash (2.75K x 24 instruction words), 2KB SRAM, 512 bytes EEPROM, 32 MHz max CPU clock (8 MIPS), 21 I/O pins, 12-bit ADC with up to 13 input channels, 2 op amps, an 8-bit DAC, 5 CCP/SCCP modules, and a hardware RTCC. The -E suffix denotes the Extended industrial temperature grade (-40C to +125C), and the /SO suffix denotes the 28-pin SOIC wide tube packaging.
The PIC24FV08KM202 architecture uses a modified Harvard bus with a 16-bit data path, 24-bit instructions, and a hardware multiply/divide unit. XLP technology provides deep-sleep currents below 1 uA, retaining RAM and running the RTCC from a 32 kHz source. The 5V-tolerant I/O simplifies interface to legacy analog front ends.
Typical applications include low-power IoT sensor nodes, industrial sensor signal conditioning, battery-powered instrumentation, consumer white goods user interfaces, USB/HID human-interface devices, and small motor control. The combination of XLP sleep current, integrated op amps, and configurable logic cells enables compact BOMs without external signal-conditioning ICs.
When designing with this part, reserve an RC oscillator option for BOM-cost-sensitive boards, but use the PLL-driven primary oscillator when USB or PWM timing precision is required. Carefully review the brown-out-reset and watchdog configuration bits during firmware bring-up, because the PIC24F power-on reset sequencing differs from older PIC16F devices.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet to help engineers select, source, and design with the PIC24FV08KM202-E/SO more efficiently.

主な用途
PIC24FV08KM202-E/SO の用途: 7 件s: Battery-Powered IoT Sensor Node, Industrial Sensor Signal Conditioning, Consumer White Goods User Interface, USB/HID Human-Interface Device, Small Motor Control / PWM Driver, Portable Medical / Wellness Device, Automotive Body Electronics.
Battery-Powered IoT Sensor Node
The PIC24FV08KM202-E/SO is purpose-built for battery-powered IoT sensor nodes thanks to its eXtreme Low Power (XLP) architecture with deep-sleep currents below 1 uA and a hardware RTCC that wakes the part from a 32 kHz source. The 8 KB Flash comfortably hosts a wireless-stack bridge or BLE proxy plus a sensor-fusion state machine, while 2 KB SRAM handles small telemetry buffers. Operating from 2.5V to 5V means it can run directly from a CR2032, two AA cells, or a small Li-ion pack without an extra LDO. The 12-bit ADC with up to 13 channels and two integrated op amps let the node digitize thermocouples, strain gauges, or electrochemical sensors without external signal-chain ICs, reducing BOM cost and quiescent draw.
おすすめ
Industrial Sensor Signal Conditioning
The PIC24FV08KM202-E/SO integrates two on-chip op amps, a 12-bit ADC, and an 8-bit DAC, which together implement bridge excitation, instrumentation-amplifier-like gain stages, and 4-20 mA loop driving entirely on-chip. The 32 MHz core executes polynomial linearization and filtering for thermocouples, RTDs, and load cells in real time without burdening the main controller. Extended -40C to +125C operation handles outdoor enclosures, motor-control cabinets, and process plants. The configurable logic cell and 5 CCP/SCCP modules also support PWM-driven excitation and timing-critical trigger pulses for sensor multiplexing.
おすすめ
Consumer White Goods User Interface
In white-goods front panels the PIC24FV08KM202-E/SO drives 7-segment displays, capacitive touch keys, and rotary encoders while polling temperature sensors over I2C or SPI. The 5 CCP/SCCP modules generate PWM for triac-fired heater elements or BLDC commutation, and the RTCC schedules delayed-start programs. The 21 I/O pins multiplex 4:8 keypads plus indicator LEDs without external I/O expanders. XLP sleep keeps standby power below IEC 62301 limits, helping the appliance meet energy-rating standards. Flash endurance of 100k cycles supports frequent firmware updates via bootloader over UART.
おすすめ
USB/HID Human-Interface Device
The PIC24FV08KM202-E/SO can run a USB HID stack with a software bit-banged low-speed USB on the 16-bit core, creating a low-cost keyboard, mouse, presenter, or custom control surface. The 8 KB Flash is enough for USB HID descriptors, debouncing, and macro scripting, while 2 KB RAM holds the HID report buffer. The integrated op amp can amplify a piezo or Hall-effect sensor input for analog input devices. The 32 MHz core meets the 1.5 Mbps low-speed USB frame timing comfortably, and XLP sleep extends battery life in wireless presenter dongles.
おすすめ
Small Motor Control / PWM Driver
With 5 CCP/SCCP modules producing up to 5 complementary or independent PWM channels and a 32 MHz CPU, the PIC24FV08KM202-E/SO is well-suited for small brushed DC, stepper, or sensored-BLDC motor control in fans, pumps, valves, and small appliances. The on-chip op amps condition back-EMF or current-sense signals, and the 12-bit ADC samples at up to 500 ksps for closed-loop torque control. XLP sleep current below 1 uA enables standby modes compliant with energy-efficiency regulations. Hardware fault inputs shut down PWM outputs within 1 instruction cycle for safe overcurrent protection.
おすすめ
Portable Medical / Wellness Device
The PIC24FV08KM202-E/SO powers portable medical and wellness devices such as pulse oximeters, blood-pressure monitors, and connected thermometers, where XLP sleep preserves battery life between measurements and the 32 MHz core handles DSP-style filtering of photoplethysmography (PPG) waveforms. The 12-bit ADC pairs with an external LED driver for SpO2 measurement, while the integrated op amps condition the photodiode transimpedance stage. Extended temperature grade supports disinfection cycles. The hardware RTCC timestamps readings for HIPAA-friendly audit logs, and 512 bytes EEPROM stores calibration constants without wearing out Flash.
おすすめ
Automotive Body Electronics
The PIC24FV08KM202-E/SO with its Extended -40C to +125C temperature grade and 5V-tolerant I/O fits automotive body-electronics nodes: door modules, seat controllers, mirror adjusters, and lighting sub-nodes. The PIC24F family is widely used in non-safety automotive body networks, and the 8 KB Flash is sufficient for LIN-slave protocol stacks. The integrated op amps condition seat-position or mirror-position analog feedback, while CCP modules drive small motor PWM. CAN/LIN peripherals enable body-network connectivity alongside the microcontroller's UART/SPI/I2C interfaces.

設計ノート
The PIC24FV08KM202-E/SO operates from 2.5V to 5V; place a 100 nF decoupling capacitor as close as possible to each VDD pin (13 and 28) and a bulk 10 uF tantalum or ceramic at the package. For battery-powered designs drawing only microamps, disable the BOR (brown-out reset) only after careful firmware validation - default BOR is recommended for production to avoid undefined behavior at low battery. The on-chip voltage regulator requires no external pass transistor, but unused VDD/VSS pins must still be connected for thermal and electrical symmetry.
Route the 32.768 kHz crystal traces on RA6/RA7 (pins 18/19) as short as possible and guard them with a ground ring to minimize load-capacitance shift from nearby digital signals. Keep the analog-input traces (RA0-RA5, RB0-RB5) away from PWM outputs and switching regulators to preserve the 12-bit ADC SNR. Place the ICSP programming header (RB6/RB7 = PGD/PGC) on the board edge with 4.7 kohm pull-up on MCLR (pin 1) to support in-circuit programming without disturbing field-deployed firmware.
A common mistake is forgetting the CONFIG words: the PIC24F uses flash configuration bits at the end of program memory that must be set correctly for oscillator source, watchdog, brown-out, code protection, and JTAG enable. Using MPLAB X IDE with the XC16 compiler's config-bit pragmas the plugin or the legacy __CONFIG macro prevents undefined behavior at first power-up. Also, do not leave the JTAG pins floating; if JTAG is disabled in CONFIG, ensure the relevant pins are reassigned to GPIO in firmware to avoid input-leakage current.
When using the internal op amps as gain stages, keep the inverting-input traces short and add a 100 pF capacitor across the feedback resistor above 10 kohm to prevent oscillation. The 12-bit ADC achieves best ENOB (~11.5 bits) at sampling rates below 200 ksps with the dedicated ADC RC anti-alias filter enabled in software; for higher sample rates, add an external RC filter on each analog input. Always include a guard ring driven by a quiet analog output around high-impedance analog input traces.
