MPN: PIC24F16KM104-I/MV ✓ פעילPIC24F16KM104-I/MV סקירה
A microcontroller is a programmable system-on-chip that combines a CPU core, non-volatile program memory, data memory, and peripherals such as ADC, timers, and communication interfaces in one package. The PIC24 family uses a 16-bit modified Harvard architecture with a 16-bit instruction set and 24-bit address space, positioned between 8-bit MCUs and 32-bit Cortex-M devices. The XLP designation identifies Microchip's nanoWatt eXtreme low-power family, built for battery-operated and always-on embedded products.
Key features of this device include an internal high-precision oscillator, Configurable Logic Cell (CLC) peripherals for hardware logic functions, flexible Capture/Compare/PWM modules, and a 12-bit ADC. The low pin-count 48-UQFN footprint measures only 6 x 6 mm, so it suits dense consumer and industrial control boards where board area is at a premium.
Architecturally, the PIC24F16KM104 family members share the same 16-bit core and peripheral set, with Flash density and analog options scaling across the KM series. The '-I/MV' suffix denotes the industrial temperature grade (-40 C to +85 C) supplied in the 48-pin 6 x 6 mm UQFN package, giving designers a single-source path for compact, low-power control designs with no external crystal required.
Typical applications include battery-powered sensor nodes and portable instrumentation, compact consumer appliances with keypad and LED interfaces, motor and lighting control using the PWM modules, and mixed-signal measurement products that need several ADC channels close to the MCU. The CLC peripherals can handle debouncing, pulse counting, or simple combinational logic, reducing the need for extra glue logic.
When designing with this part, plan the decoupling strategy for a 6 x 6 mm UQFN package: place 100 nF ceramic capacitors at each supply pin and follow the exposed thermal pad with a filled and stitched ground or thermal via array. Keep analog inputs away from switching nodes, and confirm the 1.8 V to 3.6 V operating window against the supply tolerances of your end product.

יישומים טיפוסיים
PIC24F16KM104-I/MV מתאים עבור 6 יישוםs: Battery-Powered Sensor Nodes, Compact Consumer Appliance Control, Mixed-Signal Measurement Instruments, LED Lighting and Dimming Control, Battery Management and Portable Power Systems, Industrial Control and Data Acquisition Modules.
Battery-Powered Sensor Nodes
The PIC24F16KM104-I/MV suits compact battery-powered sensing products because it runs from 1.8 V to 3.6 V with a 16-bit core that reaches 32 MHz from its internal oscillator, so no external crystal, crystal load capacitors, or extra board area are required. The 1 KB of SRAM and 512 x 8 bits of EEPROM give a node enough space for sampling buffers and stored calibration data, while 22 ADC channels allow several analog sensors to share one device. Because it belongs to the PIC24 XLP nanoWatt low-power family, sleep-mode current can be minimized for duty-cycled measurement schedules. The trade-off is that a single 6 x 6 mm UQFN carries more thermal-sensitive analog in a smaller area, so keep sensor traces away from the exposed pad and add local bypass capacitance at every supply pin.
מומלץ
Compact Consumer Appliance Control
For compact household and personal-care appliances, the PIC24F16KM104-I/MV integrates keypad scanning, motor or valve drive, and sensor readout into a single 48-pin 6 x 6 mm UQFN, leaving board area for the mechanical assembly. The flexible Capture/Compare/PWM modules handle brushless or stepper motor commutation and dimming, and the Configurable Logic Cell handles debouncing or simple combinational logic in hardware, cutting down on firmware polling. Thirty-eight I/O pins cover segmented displays, button matrices, and indicator LEDs. The 12-bit ADC option is useful for reading a potentiometer-based control or a thermistor in a toaster or kettle. The main design trade-off versus an 8-bit MCU is flash size: 5.5K instruction words is comfortable for structured state machines but tighter for large lookup tables or a rich user interface stack.
מומלץ
Mixed-Signal Measurement Instruments
The PIC24F16KM104-I/MV is described by Microchip Technology as an analog-rich low-power MCU, and the 22 ADC channels with selectable 10-bit or 12-bit resolution make it a natural fit for handheld measurement instruments such as multimeters, loggers, and process monitors. The 16-bit core at 32 MHz executes averaging, filtering, and sensor linearization routines far faster than an 8-bit part, which reduces the latency between acquisition and display. Internal EEPROM holds range calibration and unit settings across power cycles. The trade-off is the low supply ceiling of 3.6 V, so front-end signals above that range need a divider or buffer stage, and the ADC reference should be taken from a clean, decoupled node to preserve accuracy at 12 bits.
מומלץ
LED Lighting and Dimming Control
The PIC24F16KM104-I/MV can drive multi-channel LED lighting designs because its Capture/Compare/PWM modules generate precise, repeatable PWM waveforms for constant-current driver ICs, and the 38 I/O pins allow channel-enable and fault-line handling without an expander. Sixteen-bit timer resolution with a 32 MHz clock gives fine duty-cycle granularity for flicker-free dimming, while the Configurable Logic Cell can combine fault signals in hardware. The device also fits low-power accent lighting that runs from a 3.3 V rail after a buck stage. The design trade-off versus a dedicated LED driver is that PWM accuracy and channel count are shared with other timers, and total dissipation is not a concern here but jitter from a busy ISR can show as visible flicker, so keep PWM servicing in the high-priority interrupt path.
מומלץ
Battery Management and Portable Power Systems
In portable power products, the PIC24F16KM104-I/MV monitors pack voltage and current on its 22 ADC channels and manages charger state, load switches, and fuel-gauge thresholds in firmware, all while running from the same 1.8 V to 3.6 V cell range it supervises. The internal oscillator avoids the supply droop sensitivity of an external crystal, and the XLP sleep modes let the device idle between measurement cycles to extend standby life. The 16 KB Flash is enough for a full charge algorithm with logging, and EEPROM stores cell-cycle counters. The key trade-off is that measurement accuracy at very low cell voltages is limited by the 3.6 V ceiling, so the sense path usually includes a divider or level shift, and the exposed thermal pad must be tied down well to prevent self-heating from skewing the readings.
מומלץ
Industrial Control and Data Acquisition Modules
The PIC24F16KM104-I/MV works well in compact industrial control modules where a 48-pin 6 x 6 mm footprint matters, offering 38 I/O pins for discrete sensors and relay drivers alongside 22 ADC channels for analog process inputs. The 16-bit core handles PID-style loops and communication framing at 32 MHz, and the -40 C to +85 C industrial rating covers most factory-floor enclosures. Integrated EEPROM supports storing calibration and serial identification for each unit. The trade-off versus a larger 48-pin TQFP version is thermal: the UQFN's exposed pad must be tied to a solid copper pour with stitching vias, and long copper tracks carrying motor currents should be kept off the analog inputs to avoid injected noise in the 12-bit conversions.

הערות תכנון
The 48-UQFN (6 x 6 mm) body has no exposed leads, so pad and via geometry must follow the land pattern in the Microchip Technology package drawing rather than a generic QFN assumption. Place one 100 nF ceramic capacitor at each VDD and VSS pin as close to the pad as the land pattern allows, and route the exposed thermal pad to a solid ground or supply copper pour with a dense array of stitching vias. In a 1.8 V to 3.6 V design, bypassing is what keeps the internal oscillator and ADC reference quiet at 12-bit resolution.
Estimated: at 32 MHz with all peripherals active at 3.3 V, assume an average supply current of roughly 3 mA, giving about 10 mW of device dissipation and a junction temperature rise well under 1 C on the 6 x 6 mm UQFN with a proper exposed-pad pour. Even so, do not neglect the pad: self-heating in a sealed enclosure with poor copper can push internal drift several degrees, which matters if the ADC is measuring temperature. Keep at least 25 C/W effective thermal resistance from junction to ambient and avoid routing high-current return paths through the pad area.
With 22 analog inputs sharing the same package, keep analog traces short and route them away from PWM outputs, relay drivers, and switching nodes to prevent injected noise from corrupting 12-bit conversions. Reference the ADC to a decoupled supply node rather than a raw battery rail, and average multiple samples if the source impedance is high. The Configurable Logic Cell is useful for offloading input debounce and edge counting, which removes ISR jitter from the sampling path and makes the readings more repeatable.
Two errors cause most field returns on this class of part. First, treating the device as a 5 V part: the PIC24F16KM104-I/MV is specified to 3.6 V maximum, so a 5 V rail or a 5 V pull-up will damage the I/O drivers; use the PIC24FV16KM104-I/MV for 5 V operation. Second, assuming the 48-pin TQFN variant is interchangeable: the TQFP and UQFN land patterns are different, so a board built for TQFP needs a new footprint. Also confirm peripheral pin reassignment in the device data sheet before substituting a sibling part, since the CLC and timer outputs can move between pins.
