PIC24F16KM104-E/MV - 32MHz 16-Bit Low-Power MCU | Microchip
MPN: PIC24F16KM104-E/MV ✓ ActivePIC24F16KM104-E/MV Overview
A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals on one integrated circuit. The PIC24F16KM104 belongs to the PIC24F family of low-power 16-bit microcontrollers, positioned above general-purpose 8-bit devices for applications requiring greater processing performance, analog integration, and configurable control peripherals. Its nanoWatt XLP design approach targets low-power embedded systems operating from 1.8 V to 5.5 V.
Key features include a 16-bit PIC core, 5.5K x 24-word Flash organization, 1 KB of SRAM, and 512 bytes of EEPROM. The analog subsystem combines a 12-bit ADC with a DAC and operational amplifiers, reducing the need for separate components in sensor, control, and signal-conditioning systems. Flexible capture, compare, and PWM modules support timing, motor-control, and waveform-generation tasks.
The device uses a compact 48-UQFN package, making it suitable for space-constrained products while still exposing a substantial peripheral set. Its operating-voltage range supports both 3 V and 5 V equipment, while low-power features suit battery-operated instruments, environmental monitors, industrial sensing nodes, and consumer controls. The integrated analog functions make it particularly relevant to designs that require measurement, control output, and programmable gain or signal conditioning in one device.
Typical uses include industrial sensor interfaces, compact data-acquisition modules, environmental monitors, building-control nodes, motor and actuator controllers, and low-power consumer products. Designers can connect external sensors to the ADC, generate an analog reference or control voltage through the DAC, and use the operational amplifiers for local signal conditioning.
PCB implementation should follow the manufacturer pin-description table and place bypass capacitors close to the power pins. The exposed thermal pad must be connected to the intended ground plane according to the package drawing, with adequate copper area for heat dissipation. Decoupling, analog grounding, and signal-routing decisions are especially important when the ADC, DAC, and operational amplifiers operate in the same compact assembly.
This product page combines the device specifications, ordering information, package details, practical application guidance, and a constrained drop-in comparison. Because the MCU integrates program memory, RAM, EEPROM, ADC, DAC, and operational amplifiers, firmware and board validation should verify the complete peripheral mix before it replaces a less integrated design.

Typical Applications
PIC24F16KM104-E/MV is suitable for 6 applications: Industrial Sensor Interface, Environmental Monitoring, Compact Data-Acquisition Module, Motor and Actuator Control, Building Control Node, Low-Power Consumer Controller.
Industrial Sensor Interface
The PIC24F16KM104-E/MV fits compact industrial sensor nodes that need local measurement, control, and communication. Its 12-bit ADC can acquire analog sensor signals, while the 32 MHz 16-bit core supports filtering and control logic. The 1 KB RAM and 16 KB Flash provide space for embedded firmware, and the 1.8 V to 5.5 V range supports low-voltage field electronics. Use a separate precision reference if measurement accuracy requires one, and isolate analog inputs from switching nodes.
Recommended
Environmental Monitoring
The PIC24F16KM104-E/MV is appropriate for battery-operated environmental monitors combining analog sensing with low-power embedded processing. The 12-bit ADC can digitize temperature, humidity, gas, or light-sensor outputs, and the integrated DAC can generate a controllable excitation or test signal. Its nanoWurt XLP-oriented family design supports duty-cycled operation across a 1.8 V to 5.5 V supply range. Component selection should account for sensor-current demand, wake-up behavior, and analog input settling time.
Recommended
Compact Data-Acquisition Module
The PIC24F16KM104-E/MV supports compact data-acquisition modules where a 12-bit ADC, DAC, and operational amplifiers share a small 6 x 6 mm footprint. The 32 MHz core can manage sampling sequences and control logic, while 16 KB Flash holds application firmware and calibration routines. Its operational amplifiers can perform local buffering or gain conditioning, although exact input, output, and common-mode capabilities must be checked in the manufacturer pin and analog-peripheral tables before finalizing the schematic.
Recommended
Motor and Actuator Control
The PIC24F16KM104-E/MV can serve as the low-power control MCU in small motor, valve, or actuator assemblies. Its flexible Capture/Compare/PWM modules provide timing primitives for proportional control, while the ADC can monitor position or current-sense information and the DAC can produce an analog command or bias. External MOSFETs or driver circuitry are required for power switching. Size the drive stage for the load, include appropriate protection, and validate timing behavior with the actual motor mechanical requirements.
Recommended
Building Control Node
The PIC24F16KM104-E/MV is suitable for distributed building-control nodes that monitor analog inputs and operate from low-voltage power. The 1.8 V to 5.5 V operating range accommodates 3 V and 5 V systems, while the integrated ADC, DAC, and operational amplifiers reduce the external analog component count. The 32 MHz processor can support state-machine logic and timing functions. Firmware should include input filtering, sensor diagnostics, and safe-state behavior for disconnected outputs or abnormal sensor readings.
Recommended
Low-Power Consumer Controller
The PIC24F16KM104-E/MV fits compact consumer products that combine sensing, local control, and low standby demand. Its integrated 12-bit ADC, DAC, and operational amplifiers can implement a compact analog control path, while the 16-bit core handles button logic, timing, and product-state management. The 48-UQFN package helps reduce board area, and the family supports operation down to 1.8 V. Balance ADC accuracy, output settling, standby current, and accessory-control requirements through a complete power-budget calculation.

Key Differentiators
- Higher-resolution DAC than the related KM204 and KM304 (vs PIC24F16KM204)
- More integrated operational amplifiers than the related KM204 (vs PIC24F16KM204)
- Lower RAM requirement can simplify deterministic memory budgeting (vs PIC24F16KM304)
Design Notes
Use the manufacturer land pattern for the 48-UQFN 6 x 6 mm package and place the exposed-pad vias within the recommended thermal-pad region. The exposed pad is an electrical and thermal connection, not an optional mechanical feature. Confirm whether it is tied to ground in the package documentation, provide adequate plane connection, and avoid placing sensitive analog traces directly beneath the switching or high-current area.
Separate ADC inputs and DAC outputs from digital switching signals and power-conversion paths. Keep analog traces short, use a continuous ground reference, and place external bypass capacitors close to their associated supply pins. If the operational amplifiers process low-level sensor signals, evaluate input-source impedance, bias current, output drive, and settling requirements rather than assuming a general-purpose amplifier response.
Do not treat related PIC24F KM devices as automatically interchangeable. RAM, DAC resolution, operational-amplifier count, peripheral mapping, and temperature-grade requirements can change the system behavior even when Flash size and package family are similar. Revalidate the pin assignment table, startup configuration, register definitions, timing assumptions, and mixed-signal performance before replacing the PIC24F16KM104-E/MV.
Build the power budget from the actual load rather than the maximum MCU frequency alone. Account for ADC sampling activity, digital processing, analog bias current, external sensors, communications, and regulator efficiency at the selected input voltage. Low-power operation also depends on firmware-controlled sleep modes and peripheral shutdown, so measure current across the intended operating states on finished hardware.
Compliance Information
No definitive RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status was identified for the exact ordering code. Confirm compliance documentation with Microchip before using the device in regulated products.
