PIC24FV16KM202-I/SO - 16-Bit 32MHz Low-Power MCU | Microchip
料号： PIC24FV16KM202-I/SO ✓ 量产中PIC24FV16KM202-I/SO 概述
A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals on one integrated circuit. The PIC24 family belongs to the wider embedded-controller hierarchy, where a RISC processor executes application firmware and dedicated peripherals handle measurements, conversions, timing, communications, and digital control. The PIC24FV16KM202 emphasizes analog-rich, low-power embedded control rather than general-purpose computing.
The device operates with low-power characteristics associated with Microchip's eXtreme Low Power technology. Its 32 MHz operating capability supports responsive control loops, while 16 KB of Flash retains 5.5K x 24 words of program space. Integrated analog resources reduce the need for external components in sensor, actuator, and signal-conditioning systems. Flash memory also permits firmware updates without removing the device from the circuit.
The PIC24 processor core uses the RISC architecture and provides up to 16 MIPS at 3.3 V according to the family comparison information. Integrated peripherals include a 12-bit ADC, an 8-bit DAC, operational amplifiers, configurable logic cells, and flexible capture, compare, and PWM modules. These blocks allow a compact design to perform analog sensing, waveform generation, timing, and programmable digital logic without loading the processor with every peripheral transaction.
Typical applications include industrial sensor nodes, battery-powered instrumentation, compact motor and actuator controllers, low-power data-acquisition modules, consumer appliances, and connected embedded products. The 28-pin SOIC package is particularly useful where a conventional through-hole-style surface-mount footprint and manageable pin count are preferred over very small leadless packages.
Designers should verify the complete pin description, exposed analog constraints, decoupling requirements, and clock configuration in the manufacturer datasheet. Place the required supply capacitors close to their power pins, route sensitive analog inputs away from switching nodes, and confirm that the chosen operating voltage, peripheral configuration, and temperature grade satisfy the end-product requirements.
This page combines device specifications, replacement options, application guidance, and engineering design notes. These resources help engineers evaluate the PIC24FV16KM202-I/SO as a low-power, analog-rich PIC24 microcontroller and establish whether a same-package substitution can support the required firmware and board layout.

典型应用
PIC24FV16KM202-I/SO 适用于 6 应用s: Industrial Sensor and Condition Monitoring, Battery-Powered Environmental Sensing, Compact Data-Acquisition Module, Actuator and PWM Control, Consumer Appliance Control, Programmable Logic and Timing Control.
Industrial Sensor and Condition Monitoring
The PIC24FV16KM202-I/SO fits compact condition-monitoring nodes that must acquire analog sensor data while limiting overall energy use. Its 12-bit ADC supports measurements from resistive, current-based, and other analog sensors, while 2048 bytes of RAM provides working space for filtering and control routines. The 32 MHz 16-bit core can service multiple acquisition and communications tasks without requiring a larger processor. Using the integrated analog resources reduces external conditioning components in space-constrained equipment. Firmware should enable only the required peripherals during measurement cycles, then use the device's low-power modes between samples. The 28-pin SOIC package also provides a practical footprint for industrial daughterboards and compact sensor interfaces.
推荐
Battery-Powered Environmental Sensing
The PIC24FV16KM202-I/SO is appropriate for battery-powered environmental sensing because it combines low-power operation with an integrated 12-bit ADC and Flash program memory. The ADC can digitize temperature, humidity, light, or gas-sensor outputs while the 16-bit CPU performs scaling and threshold decisions. Flash permits firmware revisions without replacing the device, and the 512-byte EEPROM can retain calibration constants or counters. A duty-cycled design should measure the sensor, store a result, transmit it when needed, and return the controller to a low-energy state. This minimizes external active circuitry while keeping the board limited to a 28-pin SOIC footprint.
推荐
Compact Data-Acquisition Module
The PIC24FV16KM202-I/SO works well in a compact standalone data-acquisition module because it integrates a 12-bit ADC, 2 KB of data RAM, 512 bytes of EEPROM, and Flash program memory. The processor can buffer recent measurements, apply calibration, timestamp events, and manage a serial data interface while operating at up to 32 MHz. Its 16-bit architecture and 16 MIPS capability at 3.3 V provide useful throughput for filtering and control tasks without a large application processor. The 28-pin SOIC package simplifies assembly into multi-channel or distributed acquisition boards. Designers should select external analog front-end components according to the required input range and noise performance, then use the manufacturer pin table to avoid conflicts between analog inputs and communication peripherals.
推荐
Actuator and PWM Control
The PIC24FV16KM202-I/SO can serve as the timing controller in compact actuator and PWM systems because flexible capture, compare, and PWM peripherals handle repetitive waveform generation more efficiently than software loops. At a maximum clock frequency of 32 MHz, the 16-bit processor can coordinate feedback measurements, set operating limits, and service other control tasks. The integrated ADC provides a path for monitoring a current, position, or supply signal, while the DAC can assist with simple reference or bias generation. External driver circuitry remains necessary for loads above the microcontroller's I/O capabilities. Validate timer routing, output polarity, fault shutdown behavior, and thermal margins in the final power stage.
推荐
Consumer Appliance Control
The PIC24FV16KM202-I/SO is suitable for embedded control in compact consumer appliances where a dedicated MCU must manage buttons, displays, sensors, relays, and low-power behavior. Its 16 KB of Flash provides space for application firmware, while 2 KB of RAM supports menu state, timers, and communication buffers. The 12-bit ADC and 8-bit DAC can perform basic analog measurements and output generation, reducing the need for separate ICs. A 28-pin SOIC package is useful for appliance control boards that favor a conventional surface-mount footprint and moderate pin count. Firmware architecture should separate real-time control from noncritical display or logging tasks, and the board should include appropriate protection for relay, mains-connected, or user-accessible interfaces.
推荐
Programmable Logic and Timing Control
The PIC24FV16KM202-I/SO can implement programmable digital timing and logic functions using its configurable logic cells alongside the general-purpose 16-bit CPU. This mixed approach allows simple state-machine, debounce, waveform, or interlock logic to execute close to the associated I/O while the processor manages higher-level functions. The 32 MHz clock capability supports responsive event handling, and the integrated ADC permits analog decisions to influence the digital sequence. For a design using several interlocked signals, pin multiplexing and peripheral priorities must be mapped carefully using the manufacturer pin-description tables. The SOIC package offers enough pins for external sensors and drivers while keeping the controller compact.

设计说明
Place the required bypass capacitors directly at the PIC24FV16KM202-I/SO supply pins and follow the manufacturer layout guidance for the analog and digital supply domains. The device supports 2.5 V, 3.3 V, and 5 V operation, but each selected voltage still requires the correct decoupling and clock configuration. Keep the ground return path short, use a low-impedance plane, and avoid routing high-current return paths through the analog reference area.
Assign the 28 SOIC pins from the manufacturer pin-description table before finalizing the PCB footprint. The integrated ADC, DAC, op amps, programming pins, and timer functions can constrain the usable I/O assignment. Reserve programming access, connect unused inputs according to the electrical guidance, and preserve the package orientation and pin-1 marking so the controller is assembled and serviced consistently.
Do not assume that two order codes with similar MCU family names are production-equivalent without checking their qualification and packaging suffixes. For a migration involving PIC24FV16KM202T-I/SO or PIC24F16KM202-E/SO, compare the complete ordering information, operating-temperature limits, device identifier, programming configuration, and package shipping format. A same-footprint device can still require different software settings or a different procurement format.
Route analog inputs and op-amp connections away from switching nodes, high-current motor traces, and digital clock signals. Keep the analog ground connection strategy consistent with the manufacturer guidance and use the shortest practical path to the device pins. The 12-bit ADC can provide useful measurement resolution, but its practical accuracy also depends on source impedance, reference stability, layout-induced noise, and appropriate input filtering.
