PIC24FV08KM204T-I/ML 概要
A PIC24F microcontroller is a 16-bit modified Harvard RISC core from Microchip's PIC24F family, positioned between 8-bit PIC16/PIC18 parts and 32-bit PIC32 devices. Within the broader taxonomy: PIC24F -> 16-bit microcontroller -> microcontroller (MCU) -> embedded controller -> semiconductor. XLP (eXtreme Low Power) parts add nanoWatt technology peripherals such as deep sleep, RTC, and ultra-low-power watchdog, allowing the chip to extend battery life in always-on applications.
Key features include an integrated 12-bit A/D converter with up to 16 input channels, dual 8-bit DACs, three operational amplifiers, three analog comparators, a configurable logic cell (CLC), and multiple PWM/SCCP/MCCP timers. Communication peripherals include UART, SPI, I²C, and IrDA support. The 44-QFN exposed-pad package provides low thermal resistance and a compact 8x8 mm footprint suitable for dense PCB designs.
Typical applications include portable medical instruments, USB human-interface devices, sensor hubs, low-power wireless sensor nodes, and e-metering front ends. The wide 2.0–5.5 V supply range also suits industrial 24 V bus pre-regulation post-buck stages.
For best noise performance, place 0.1 µF ceramic decoupling capacitors adjacent to every VDD/VSS pair and connect the QFN exposed pad to a solid ground plane. Designers migrating from older PIC24F parts should review the Configurable Logic Cell configuration - misconfigured CLC blocks are a common first-prototype failure mode.

主な用途
PIC24FV08KM204T-I/ML の用途: 7 件s: Portable Medical Glucose Meter, Industrial Sensor Transmitter (4-20 mA Loop-Powered), USB Human Interface Device (HID) Game Controller, Smart Metering Display and Tamper Detect, Battery-Powered IoT Sensor Hub, Automotive Aftermarket Accessory Controller, Consumer Audio DAC Pre-Amp Front End.
Portable Medical Glucose Meter
The PIC24FV08KM204T-I/ML fits portable glucose meters because its 2.0-5.5 V VDD range accepts 2x AAA cells end-of-life (2.0 V) up to a USB charger supply (5 V) without a boost regulator. The integrated 12-bit ADC with up to 16 channels directly digitizes the electrochemical strip current and reference channel, while the three on-chip op-amps condition the transimpedance signal before ADC sampling. The dual 8-bit DAC and three analog comparators provide temperature-compensation calibration biasing. XLP deep-sleep current under 100 nA stretches battery life on meters that sleep most of the day. Estimated: 32 MIPS is sufficient for USB-CDC firmware stacks and Bluetooth Low Energy HCI forwarding via UART.
おすすめ
Industrial Sensor Transmitter (4-20 mA Loop-Powered)
The PIC24FV08KM204T-I/ML is well-suited for 4-20 mA industrial loop transmitters because its 2.0 V minimum supply operates from the 12 V loop voltage after a shunt regulator, and its integrated 12-bit ADC and op-amps condition the bridge pressure or RTD sensor directly. The three analog comparators handle fault thresholds and HART modem envelope detection. XLP nanoWatt sleep modes keep total loop current below 3.5 mA when the transmitter idles, preserving compliance with the IEC 61158-2 4-20 mA budget. Estimated: at 3.3 V and 32 MHz, active current is approximately 8 mA, leaving 5 mA for sensor excitation and HART modulation. The 44-QFN exposed pad provides low thermal resistance for the warm industrial enclosure.
おすすめ
USB Human Interface Device (HID) Game Controller
The PIC24FV08KM204T-I/ML supports USB-HID game controllers when paired with an external USB transceiver and crystal, using its UART and GPIO peripherals for button debouncing and analog stick ADC sampling. The 32 MIPS at 32 MHz is sufficient for HID report packing at 1 kHz and on-device button remapping logic. The 2.0-5.5 V range allows direct 5 V USB VBUS powering of the analog rail. The 8 KB Flash holds HID descriptor tables plus 4 KB of macro code, while 2 KB SRAM buffers HID report queues. Note: PIC24FV08KM204T-I/ML lacks on-chip USB; designers needing single-chip USB should consider PIC24FJ64GB002-I/ML. Estimated: 32 MHz provides comfortable headroom for debounced 1 kHz sampling on 16 ADC channels.
おすすめ
Smart Metering Display and Tamper Detect
The PIC24FV08KM204T-I/ML fits smart-meter front-panel display drivers and tamper-detect circuits because its integrated three op-amps condition Hall-effect current-sensor signals while the three analog comparators detect magnetic tamper events in real time. The 12-bit ADC with up to 16 channels samples display drivers and tamper sensors in sequence without CPU intervention. XLP deep-sleep with RTC keeps calendar functions running on a coin cell during outages. The 44-QFN 8x8 mm package fits the dense layout constraints of single-phase residential meters. Estimated: at 32 MHz the MCU can scan all 16 ADC channels in under 200 µs per cycle, well inside the 4 kHz bandwidth required for tamper detection.
おすすめ
Battery-Powered IoT Sensor Hub
The PIC24FV08KM204T-I/ML is ideal for battery-powered IoT sensor hubs that aggregate multiple analog sensors over UART/I2C/SPI and forward over BLE or LoRa. The XLP nanoWatt technology drops quiescent current to nanoampere levels between sensor reads, while the 32 MIPS burst-mode CPU handles compression and encryption. The wide 2.0-5.5 V VDD allows 2x AA alkaline, single Li-ion, or USB-direct powering without external regulators. Three op-amps and three comparators support analog sensor front-ends without external components. The 8 KB Flash holds a simple TLS stack or SigFox/LoRaWAN L1 firmware, and 2 KB SRAM buffers sensor frames. Estimated: a 2500 mAh Li coin cell with 0.1% duty-cycle sensor reads yields 5+ year battery life at room temperature.
おすすめ
Automotive Aftermarket Accessory Controller
The PIC24FV08KM204T-I/ML serves automotive aftermarket accessory controllers such as lighting strips and seat heaters, where its wide 2.0-5.5 V supply directly tolerates 12 V automotive transients after a simple LDO. The integrated 12-bit ADC samples battery voltage and thermistor NTC inputs for temperature-aware PWM control, while the SCCP/MCCP PWM modules drive MOSFET gates directly. The 32 MIPS at 32 MHz handles LIN-protocol slave responses. The 44-QFN exposed pad withstands thermal cycling better than SSOP packages in engine-bay-adjacent mounting locations. Note: For OEM automotive designs requiring AEC-Q100, choose PIC24FV08KM204-I/PT-Q1 or another Q1-graded part. Estimated: AEC-Q100 Grade 3 (-40 to +85 °C) parts are not specified for this 'I' industrial-grade variant.
おすすめ
Consumer Audio DAC Pre-Amp Front End
The PIC24FV08KM204T-I/ML fits audio DAC front-end volume and tone-control pre-amps because the dual 8-bit DACs drive analog potentiometer emulators while the 12-bit ADC digitizes rotary encoder inputs. The three on-chip op-amps implement active filter stages for sub-bass and treble tone control. The 32 MIPS handles button debouncing, display refresh, and rotary encoder quadrature decoding in real time. The wide 2.0-5.5 V range supports both 3.3 V digital logic and 5 V analog signal chains without level shifters. The 44-QFN small footprint suits compact hi-fi components. Estimated: 32 MHz provides headroom for 8-band parametric EQ update without audible zipper noise during parameter changes.

設計ノート
Decoupling: Place 0.1 µF ceramic decoupling capacitors adjacent to every VDD/VSS pin pair (pins 9, 10, 26, 27, 44 plus EP). Add one bulk 10 µF tantalum or ceramic near the device. The exposed thermal pad (EP) MUST be soldered to a continuous ground plane for thermal dissipation and electrical reference - skip via-in-pad plating if the board has lead-free solder, and use thermal vias array (at least 9 vias at 0.3 mm pitch) under EP. The Microchip datasheet specifies a 0.5 mm pad pitch for QFN land.
Configurable Logic Cell (CLC) misconfiguration is the most common first-prototype failure on PIC24FV08KM204T-I/ML designs. The CLC module can route any of 8 input sources to 4 outputs, but failure to drive all CLC inputs leaves floating outputs that draw extra current and may cause unexpected peripheral toggling. Always write a CLC initialization routine even if you do not plan to use CLC - configure all CLC blocks to OFF and set outputs to 0. Additionally, ensure unused ADC inputs are tied to VSS through 10 kΩ rather than left floating.
Estimated: At maximum active state (32 MHz, all peripherals on, both op-amps driving 1 mA loads), the PIC24FV08KM204T-I/ML dissipates approximately 50 mW. With the 44-QFN thermal resistance of approximately 35 °C/W on a standard 2-layer board, the junction-to-ambient rise is roughly 1.7 °C above ambient. On a 4-layer board with full ground pour, theta_JA drops to approximately 18 °C/W, giving less than 1 °C rise. No heatsink is required; derating is unnecessary below +85 °C ambient. Industrial-grade parts (-40 to +85 °C) can be used up to +70 °C ambient without airflow for full MIPS operation.
XLP nanoWatt sleep current on the PIC24FV08KM204T-I/ML is typically 20 nA in deep sleep with RTC running. To achieve this minimum, disable all unused peripherals via PMD registers (peripheral module disable), switch the system clock to LPRC (31 kHz internal RC) before entering Sleep, and ensure no floating inputs are present. Wake-up latency from deep sleep is approximately 100 µs at 32 MHz FRC, so design any wake-event task with this delay in mind. Estimated: an IoT sensor hub reading 1 sample per minute achieves 5+ year battery life on a CR2477 coin cell with these settings.
