PIC24F16KM102-E/SS - 16-Bit 32MHz MCU | Microchip Technology
料号： PIC24F16KM102-E/SS ✓ 量产中PIC24F16KM102-E/SS 概述
A microcontroller is a programmable semiconductor that integrates a CPU core, nonvolatile program memory, data memory, and peripherals such as timers, serial interfaces, and analog converters on one device. The PIC24F16KM102 belongs to the PIC24F family of 16-bit microcontrollers, the PIC XLP low-power product family, and the broader embedded-control semiconductor category. This integration reduces component count and allows firmware to control measurement, communication, and actuator functions in a single compact circuit.
Key features include a 16-bit PIC core, operation up to 32 MHz, 16 KB of Flash organized as 5.5K x 24 bits, 1 KB x 8 RAM, and 512 x 8 EEPROM. The device also provides a 12-bit ADC, comparator, MCCP/SCCP peripherals, configurable logic cells, and communication interfaces including I2C, SPI, UART/USART, IrDA, and LINbus. These resources support both periodic control and low-rate serial networking.
The PIC XLP architecture emphasizes low-power operation, while the flexible capture/compare/PWM modules support timing, motor-control, and signal-generation functions. The 12-bit ADC enables analog sensor acquisition without adding a separate converter. Data can be retained in EEPROM for calibration values or configuration parameters, although firmware should observe the device's endurance and write-cycle limits when using it for frequently changing information.
Typical applications include compact industrial controllers, low-power sensor nodes, building-control modules, appliance controllers, motor-control peripherals, and LIN-connected automotive or transportation equipment. The 28-pin SSOP package is useful when a design needs more I/O than a small microcontroller package can provide while remaining compatible with conventional surface-mount assembly.
Designers should confirm the exact pin assignments, peripheral multiplexing, voltage limits, decoupling requirements, and programming configuration in the manufacturer datasheet before layout is released. Place the required bypass capacitors close to the supply pins, provide clean analog grounding for ADC measurements, and route high-current switching outputs away from sensitive analog inputs to minimize coupling and measurement errors.
This product page combines the manufacturer specifications, package information, practical application guidance, and drop-in replacement analysis. It also provides engineering-focused comparison notes that help identify differences in memory, core speed, peripheral availability, and qualification requirements before a PCB or firmware migration is attempted.

典型应用
PIC24F16KM102-E/SS 适用于 6 应用s: Industrial Sensor Node, Appliance Control Module, Motor and PWM Control, LIN-Connected Control Unit, Building Control Interface, Battery-Powered Data Logger.
Industrial Sensor Node
The PIC24F16KM102-E/SS fits compact sensor nodes that need local acquisition and low-power control. Its integrated 12-bit ADC can process analog sensor signals, while 1 KB of RAM and 16 KB of Flash support calibration and application firmware. I2C and SPI provide local peripheral connectivity, and the 32 MHz core can combine measurement, filtering, and communication tasks without an external processor. Keep analog inputs short and place the required bypass capacitors close to the device.
推荐
Appliance Control Module
The PIC24F16KM102-E/SS can serve as the central controller in a compact appliance because it combines 16 KB of Flash, 1 KB of RAM, EEPROM, a 12-bit ADC, and multiple timer outputs in one package. The MCCP/SCCP resources can generate or capture timing signals for motors, valves, or indicators. Its I2C, UART/USART, and SPI interfaces support displays and sensors, while the 28-pin SSOP footprint simplifies conventional surface-mount assembly.
推荐
Motor and PWM Control
The PIC24F16KM102-E/SS is appropriate for small motor, lighting, or actuator-control boards where PWM generation and digital feedback are needed. Its MCCP/SCCP peripherals provide configurable capture and compare channels, while the 32 MHz core leaves timing headroom for control-loop execution. The comparator can support threshold detection and the ADC can monitor current or position signals. Validate the pin multiplexing and keep switching-node routing separated from analog measurement traces.
推荐
LIN-Connected Control Unit
The PIC24F16KM102-E/SS supports LINbus and UART/USART connectivity, making it suitable for distributed low-speed control networks. Firmware can acquire sensor data through the 12-bit ADC, apply control logic, and communicate through the network interface without adding a separate communications controller. The 512-byte EEPROM is useful for retaining configuration or calibration data. Confirm the transceiver requirement, bus timing, and pin multiplexing in the application circuit.
推荐
Building Control Interface
The PIC24F16KM102-E/SS can support compact building-control interfaces that combine environmental sensing, local logic, and serial communications. Its integrated ADC and comparator reduce the component count for analog inputs, while EEPROM can hold calibration and configuration values. I2C is suitable for sensors and expanders, and UART/USART or LINbus can connect the module to broader equipment. The low-power XLP positioning is useful in distributed controllers that spend much of their time in reduced-activity states.
推荐
Battery-Powered Data Logger
The PIC24F16KM102-E/SS is suitable for battery-powered data logging when memory, mixed I/O, and low-power operation are more important than high data throughput. Its 16-bit core supports timestamped sampling and local processing, while the ADC and comparator handle sensor thresholds. EEPROM can preserve selected operating parameters, and UART/USART can transfer records to a host. Determine the actual duty cycle and sleep-current behavior in firmware because system battery life depends on the complete load-switching strategy.

设计说明
Place the required input bypass capacitors immediately adjacent to the supply pins and connect them to a low-impedance ground plane. Follow the manufacturer pin-description table for decoupling and exposed thermal requirements. Route sensitive analog inputs away from PWM, switching, and high-current return paths; keeping the analog ground and digital return strategy consistent reduces ADC measurement disturbance.
Design the 3.3 V supply for both steady-state demand and transient events caused by ADC sampling, communications, and PWM activity. Confirm the exact operating-voltage range and current limits in the Microchip datasheet before selecting regulators or bulk capacitance. For battery-powered products, calculate average consumption from the firmware duty cycle because the MCU's active current, peripheral load, and sleep behavior determine the overall energy budget.
Do not assume that a shared SSOP package guarantees a drop-in replacement. Verify every used pin, alternate function, supply requirement, interrupt mapping, peripheral feature, and programming configuration. The PIC24FJ16GA002T-I/SS occupies the same package class but belongs to a different family, while PIC24F16KM102-I/SS changes the grade code; both require explicit review before schematic or PCB substitution.
Treat programming, reset, clock, and serial interface routes as sensitive nets even though this is a low-pin-count MCU. Keep traces short, provide a stable clock or suitable external oscillator arrangement as applicable, and avoid routing communications signals parallel to switching outputs. Validate the final board with an oscilloscope during startup, peripheral activation, and maximum supported communication activity.
