MPN: PIC24F16KM204-I/ML ✓ AktifPIC24F16KM204-I/ML Ringkasan
A microcontroller (MCU) is a single-chip computer that combines a CPU core, non-volatile program memory (Flash), volatile working memory (RAM), and a set of programmable peripherals such as ADCs, timers, communication controllers and I/O. In the broader system hierarchy a PIC24F sits in the PIC24 family of 16-bit microcontrollers, which itself is part of Microchip's 8/16/32-bit MCU portfolio alongside PIC16, PIC18 and PIC32. The "XLP" (eXtreme Low Power) designation means the part is engineered for ultra-low sleep current, typically relevant for battery-powered and energy-harvesting designs.
Key features include operation from 1.8 V to 5.5 V (with full analog performance at 3 V and 5 V), 32 MIPS at 32 MHz, 16 KB self-programmable Flash, 2 KB RAM, integrated 12-bit ADC, 8-bit DAC, two op amps, two comparators, CLC module, Capture/Compare/PWM modules, and standard peripherals such as UART, SPI and I²C. The PIC24F KM family is designed for sensor conditioning, mixed-signal front ends and small-form-factor embedded products.
Architecturally the device uses a 16-bit modified-Harvard core with a 24-bit instruction word, a 17-bit x 17-bit hardware multiplier, and zero-overhead loop control. The peripheral set is clocked from the system peripheral bus, and the analog chain shares a common voltage reference, which simplifies PCB routing when many analog channels are needed.
Typical applications include low-power sensor interfaces, portable medical devices, IoT edge nodes, industrial control front ends, and consumer devices that require on-chip signal conditioning. The integrated op amps and DAC reduce the bill of materials for transducer signal chains.
When designing with this part, plan the analog pinout first because the QFN-44 package shares supply and reference pins between analog and digital domains. Decouple VDD/VSS with 100 nF ceramics placed within 3 mm of each supply pin, and add a bulk 10 µF capacitor at the regulator output to handle ADC charge kicks.

Aplikasi Umum
PIC24F16KM204-I/ML cocok untuk 6 aplikasis: Battery-Powered Sensor Signal Conditioning, Portable Medical Monitoring Devices, Industrial Control Front Ends, IoT Edge Nodes and Smart Sensors, Consumer Audio and Lighting Control, Automotive Body Electronics (non-safety).
Battery-Powered Sensor Signal Conditioning
The PIC24F16KM204-I/ML is well suited to battery-powered sensor front ends because it combines a 12-bit ADC, 8-bit DAC, two integrated op amps and two comparators in a single QFN-44 device. The op amps can be configured as transimpedance or instrumentation stages, removing the need for external analog ICs and shrinking the sensor-node BOM. With its 1.8 V to 5.5 V supply range and XLP-class sleep currents, the part runs directly from a single lithium coin cell or two AA cells. Nanoamp sleep currents extend coin-cell lifetime to multi-year levels in periodic-sampling duty cycles. The 32 MIPS core handles digital filtering, linearization and basic sensor-fusion loops before the data is handed off via UART, SPI or I²C.

Portable Medical Monitoring Devices
The PIC24F16KM204-I/ML fits portable medical devices such as pulse oximeters, glucose meters and wearable thermometers where low noise and low power both matter. Its integrated 12-bit ADC and op amps provide a clean analog front end for bioelectric or optical sensors without external instrumentation amplifiers, which is critical for ECG-style and pulse-oximetry signal chains. The wide 1.8 V to 5.5 V supply range lets designers use a single-cell Li-ion or Li-polymer battery without additional regulators. Its XLP architecture delivers sub-microamp sleep currents, allowing continuous-wear devices to wake periodically and stream data over BLE without depleting the battery. The 16 KB Flash comfortably holds device firmware, calibration tables and basic BLE control profiles.

Industrial Control Front Ends
For industrial sensor and control front ends, the PIC24F16KM204-I/ML offers the integrated analog peripherals needed to read 4-20 mA loops, bridge sensors or thermocouples without external signal conditioning. The two on-chip op amps can be wired as differential or instrumentation amplifiers, while the comparators handle fast over-limit detection. With 32 MIPS of compute headroom and 16 KB of Flash, the part can run basic PID loops or run Modbus RTU over UART. The industrial -40C to +85C temperature rating supports factory-floor and outdoor cabinets. CLC module enables discrete-logic replacement for glue functions between ADC, PWM and trip comparators.

IoT Edge Nodes and Smart Sensors
IoT edge nodes benefit from the PIC24F16KM204-I/ML combination of low-power XLP operation and on-chip analog signal conditioning. The MCU can wake from sleep, sample a sensor through its 12-bit ADC and integrated op amp, do local decision logic, and forward results via UART, SPI or I²C to a host radio module. Its 16 KB Flash and 2 KB RAM are enough for small protocol stacks and local calibration storage. The 1.8 V to 5.5 V range simplifies battery selection for solar, coin-cell or 2xAA powered nodes. Designers can use the CLC peripheral to implement glue logic in firmware rather than adding gates.

Consumer Audio and Lighting Control
The PIC24F16KM204-I/ML is well matched to consumer lighting and audio peripherals that need PWM, DAC and analog sensing in a small package. The Capture/Compare/PWM peripherals drive LED dimmers, motor control or audio DAC outputs, while the 12-bit ADC reads ambient light, potentiometers or touch sensors. The two op amps can be configured as audio preamplifiers for line-level signals, and the comparators enable over-current or thermal foldback. With a 44-pin QFN, the part fits compact consumer enclosures. XLP sleep currents support battery-powered remote controls and handheld devices.

Automotive Body Electronics (non-safety)
For non-safety automotive body electronics such as interior lighting, climate-control modules and seat-control nodes, the PIC24F16KM204-I/ML provides the analog-rich peripherals required to drive PWMs, read sensors and handle LIN communication. The integrated 12-bit ADC and op amps simplify current sensing in motor drivers, while the comparators handle fault detection. The extended-temperature -E variant is preferred when ambient temperatures under the dash exceed 85C. Note that AEC-Q100 qualification is not listed for this part - the KM family is not automotive-qualified, so safety-relevant functions require a Q-grade MCU.

Catatan Desain
The PIC24F16KM204-I/ML supports a wide 1.8 V to 5.5 V supply range, but the 12-bit ADC achieves full specified performance only at 3 V and 5 V operation. Use a low-noise LDO such as Microchip MCP1700 or MCP1755 to feed both VDD and AVDD if the source is a switching regulator. Place a 100 nF decoupling capacitor within 3 mm of every VDD/VSS pin pair, and add a 10 uF bulk capacitor at the regulator output to absorb ADC charge kicks. Do not share decoupling between VDD and AVDD - keep the analog and digital ground returns separate and join them at a single point near the MCU.
Estimated: the PIC24F16KM204-I/ML in QFN-44 has a junction-to-ambient thermal resistance of approximately 35 C/W on a 1 oz 4-layer PCB with thermal vias under the exposed pad. At 32 MHz full activity the core dissipates around 30 mW, yielding a junction rise of roughly 1 C above ambient - thermal management is not a concern. Solder the central thermal pad to a copper pour stitched with thermal vias to a bottom-layer ground plane; an unsoldered thermal pad can raise theta_JA by 30-40% and is a common root cause of borderline thermal failures in enclosed industrial housings.
Route analog traces (ANx, OA1IN+, OA1IN-, OA2IN+, OA2IN-) over a continuous analog ground pour and keep them short. Avoid routing digital signals (especially PWM, oscillator, and SPI clock) across the analog section - they couple via the ground reference. The 44-pin QFN has a 0.65 mm pitch which requires 0.2 mm/0.2 mm clearance trace and space rules at the fab; use 0.5 oz copper on outer layers if the PCB is flex or thin. Keep the crystal within 8 mm of OSC1/OSC2 to avoid EMI susceptibility, and guard OSC2 with a ground trace if it routes through dense digital areas.
Do not confuse PIC24F with PIC24FV - the FV variant has battery-backed SRAM and different supply pin functions on the same 44-pin QFN footprint, so it is NOT pin-compatible. Do not program the CONFIG words to disable the internal voltage regulator if the system relies on the internal 1.8 V core supply; the part locks up without it. Always configure unused I/O as outputs (not inputs) to minimize shoot-through current. The NRST (MCLR) pin must be pulled high through a 10 kohm resistor for normal operation; leaving it floating is a common factory-mode entry path that prevents code execution.
