PIC24F16KM104-E/PT - 16-Bit 32MHz MCU | Microchip Technology
料号： PIC24F16KM104-E/PT ✓ 量产中PIC24F16KM104-E/PT 概述
A microcontroller is a programmable control component that combines a processor core, memory, peripherals, and communication interfaces on one integrated circuit. The PIC24F KM family belongs to the broader embedded-control hierarchy of low-power microcontrollers, mixed-signal systems, and semiconductor devices. This combination of digital processing and analog peripherals allows compact designs to sense physical inputs, control outputs, and communicate with external equipment without requiring several discrete components.
PIC24F16KM104-E/PT provides 16 KB of Flash memory organized as 5.5K words by 24 bits, together with 1 KB of data RAM and 512 bytes of nonvolatile EEPROM. Its 32 MHz processing rate supports responsive control tasks, while the integrated analog resources reduce board area. The device also includes I2C, SPI, UART/USART, IrDA, and LINbus connectivity according to the manufacturer product information.
The -E/PT ordering designation identifies the extended-temperature automotive-grade variant in a 44-lead TQFP tray package. This distinction is important because the same base device can also appear with different temperature grades, package forms, and packing options. Automotive qualification requirements should be confirmed against the complete ordering table before production release rather than inferred from the ordering code alone.
Typical uses include low-power sensor nodes, compact industrial controls, automotive accessory modules, battery-powered instrumentation, and communication-enabled monitoring equipment. The mixed-signal peripherals are particularly useful where a board must measure an analog input and condition or generate an analog output while retaining serial connectivity for a host controller or service interface.
Designers should account for analog reference quality, ADC acquisition time, DAC settling behavior, and the current limits of each I/O pin. Decoupling capacitors should be placed close to the supply pins, and unused inputs should be configured according to the manufacturer's guidance. The package has 44 terminals, so pin assignment and trace routing should follow the official pin-description table in the manufacturer datasheet.
This product summary combines the core memory, processing, analog, interface, package, and ordering characteristics with practical guidance for MCU-based designs. It also distinguishes the documented device from temperature-grade and package alternatives that may appear in searches but are not automatically interchangeable without checking the complete ordering information.

典型应用
PIC24F16KM104-E/PT 适用于 6 应用s: Automotive Sensor Interface, Industrial Condition Monitoring, Battery-Powered IoT Node, Precision Analog Control Module, Automotive Accessory Controller, Communication-Enabled Data Logger.
Automotive Sensor Interface
The PIC24F16KM104-E/PT suits compact automotive sensing modules because it combines a 32 MHz 16-bit core, 16 KB of Flash, 1 KB of RAM, and an integrated 12-bit ADC in a 44-TQFP package. It can acquire sensor inputs, apply digital filtering, retain calibration values in 512 bytes of EEPROM, and communicate through LINbus, UART/USART, SPI, or I2C. The extended automotive temperature suffix supports its use in this environment, subject to confirmation of the exact qualification record. Compared with a discrete analog front end plus separate controller, the integrated ADC and communication peripherals reduce component count and board area while retaining an event-driven low-power design path.
推荐
Industrial Condition Monitoring
The PIC24F16KM104-E/PT can form the control center of a compact industrial condition-monitoring node. Its 12-bit ADC accepts analog inputs from pressure, temperature, or current sensors, while the 32 MHz processor supports sampling schedules, filtering, fault detection, and local data preparation. UART/USART, I2C, SPI, IrDA, and LINbus connectivity allow the node to connect to local sensors, a gateway, or service equipment without multiple protocol controllers. The 1.8 V to 5.5 V operating range supports both low-voltage sensing electronics and conventional 5 V industrial circuits. EEPROM provides a modest nonvolatile area for thresholds or calibration constants, while selectable sleep behavior should be used to reduce standby consumption.
推荐
Battery-Powered IoT Node
PIC24F16KM104-E/PT is well suited to a compact battery-powered IoT node that measures a physical quantity and reports it through a serial link. The low-power PIC24F KM architecture supports a design that spends most of its time in a low-energy state and activates periodically for sampling and communication. Its 12-bit ADC handles analog sensors, and the 1.8 V to 5.5 V range accommodates energy-harvesting front ends and common 3.3 V logic. I2C or SPI can connect a compact sensor, while UART/USART or LINbus supports a gateway connection. The 512-byte EEPROM is useful for a limited set of configuration values, although persistent application data should not be assumed to have large capacity.
推荐
Precision Analog Control Module
The integrated analog resources make PIC24F16KM104-E/PT appropriate for a compact closed-loop control module. The 12-bit ADC can acquire a control or feedback signal, the 32 MHz CPU can calculate an output update, and the DAC can provide an analog command where the application requires it. Operational amplifiers can assist with signal conditioning, subject to the datasheet's supported input, output, and configuration limits. This mixed-signal arrangement can replace separate ADC, DAC, and op-amp circuitry in modest embedded systems. For accurate results, reference-voltage stability, analog input acquisition time, output settling, and grounding must be considered; digital PWM and communication activity should be arranged to minimize disturbance on sensitive analog nodes.
推荐
Automotive Accessory Controller
PIC24F16KM104-E/PT can serve as the central controller in a compact automotive accessory module that handles switch inputs, low-power sensing, and communication with the vehicle network. Its 32 MHz 16-bit processor provides deterministic control for motor, relay, or indicator functions, while integrated ADC support can monitor analog feedback. LINbus and UART/USART suit vehicle or service-network communication, and SPI or I2C can connect sensors or external memory. The 44-TQFP package supports a conventional surface-mount assembly with accessible perimeter leads. Production selection should require review of the exact automotive qualification record, transient protection, temperature range, and load-driving limits before external actuators are connected.
推荐
Communication-Enabled Data Logger
The PIC24F16KM104-E/PT can act as a local data logger in equipment that records sensor activity and forwards summarized information. Its 16 KB of Flash supports compact firmware, while 1 KB of RAM is suitable for short acquisition buffers and protocol handling. The 12-bit ADC acquires changing analog inputs, and the integrated DAC can generate test or excitation signals when required. I2C, SPI, UART/USART, IrDA, and LINbus provide several ways to connect external storage, a host, or a remote node. Because RAM is limited, logging should use buffered transfers or external storage rather than assuming long sample histories fit internally. EEPROM can preserve configuration, counters, or calibration information across power cycles.

设计说明
Plan the power tree around the device's 1.8 V to 5.5 V operating range and verify every peripheral rail against the manufacturer electrical limits. Place the required decoupling capacitors next to the corresponding supply pins, keep the analog supply path quiet, and provide suitable filtering for communication lines entering the board. If the design mixes 5 V peripherals with low-voltage MCU I/O, use direction-controlled level shifters rather than relying on internal tolerance. Review average and peak current requirements before selecting the upstream regulator because the MCU, ADC, communications, and external loads determine the total budget.
Use the official 44-TQFP pin-description table to assign analog and digital functions before routing the board. Keep analog inputs, the analog reference, and DAC outputs away from high-current switching nodes and fast digital clock traces. Use a continuous ground plane where practical, place analog bypass capacitance near the pins, and keep sensitive traces short. The 10 mm by 10 mm TQFP has exposed perimeter leads, so inspect the manufacturer land pattern and paste stencil rather than relying on a generic TQFP footprint library. Confirm courtyard clearance and lead geometry during PCB-library creation.
Do not assume that devices with the same 44-TQFP outline are interchangeable. PIC24F16KM104-I/PT changes the temperature-grade designation, while the PIC24FJ alternatives use different device families with different peripheral assignments. Before substituting a part, compare MCU pin functions, analog channels, alternate-function mappings, clock sources, communications, memory limits, and development-tool support. Also verify that existing firmware remains compatible with the selected alternative. This is especially important for the integrated DAC and operational amplifiers because moving those functions to another family can require board and software changes despite identical package dimensions.
For sensor measurements, establish an acquisition sequence that allows the ADC sample-and-hold circuit to settle and uses the manufacturer's recommended input source impedance. Keep sensor returns and analog grounds quiet, and avoid routing ADC inputs beside clock, PWM, or communication outputs wherever the board geometry permits. When using the DAC for excitation or control, check output settling and load limits against the required waveform bandwidth. A software averaging filter can reduce periodic interference, but it cannot compensate for an unsuitable analog layout or an out-of-range input.
