PIC24FV16KM104-E/PT 概述
What is a PIC24F microcontroller? A PIC24F is a 16-bit modified-Harvard RISC microcontroller from Microchip Technology that occupies the middle ground between the 8-bit PIC16/PIC18 families and the 32-bit PIC32MX/dsPIC families. It uses a 16-bit data path, 24-bit instruction word, hardware multiply/divide, and a tightly-coupled peripheral set. Within the PIC24F family hierarchy (PIC24F → PIC24FJ → PIC24FV), the "FV" suffix indicates the wide-voltage 2.0V-5.5V variant optimized for battery and mixed-rail designs, while the "KM" series is the nanoWatt XLP extreme-low-power sub-line.
Key features of the PIC24FV16KM104 include 1 KB of SRAM, 512 bytes of EEPROM, a 12-bit ADC with up to 22 input channels, multiple Capture/Compare/PWM (MCCP/SCCP) modules for motor and power control, and serial interfaces including I²C, SPI, UART/USART, IrDA, and LIN. The device also integrates configurable logic cells, comparators, brown-out reset, low-voltage detect, power-on reset, and a watchdog timer.
Architecturally, the PIC24FV16KM104 leverages the same 16-bit modified-Harvard core used across the PIC24F family, with single-cycle 16×16-bit MAC hardware for DSP-class signal processing at microamp power budgets. The XLP nanoWatt technology enables sleep currents in the microamp range while retaining RAM, allowing battery-powered sensors to wake on interrupt without external RTC chips.
Typical applications include automotive body and interior modules (LIN nodes, sensor conditioning), low-power IoT edge nodes, portable medical devices, human-interface products with mTouch capacitive sensing, and battery-powered industrial telemetry. The 44-TQFP footprint also supports hand-soldered prototypes and low-volume production.
When designing with this device, allocate pin functions carefully because the 44-pin package limits GPIO to 37 I/Os. Use MPLAB X IDE plus MCCB code generator for peripheral setup, and verify the wide-voltage 2.0V-5.5V analog and timing parameters if migrating from a 3.3V-only PIC24FJ variant.

典型应用
PIC24FV16KM104-E/PT 适用于 7 应用s: Automotive Body Electronics (LIN Nodes), Battery-Powered IoT Edge Sensors, Portable Medical Devices, Industrial Control & HMI, USB Consumer Peripherals, Motor Control & PWM Drivers, Home & Building Automation.
Automotive Body Electronics (LIN Nodes)
The PIC24FV16KM104-E/PT is well suited for LIN bus slave nodes in automotive body and interior modules such as door/window controllers, seat adjusters, mirror modules, and ambient lighting. Its wide 2.0V-5.5V VDD accepts 12V battery feeds after a simple LDO, the -40°C to +125°C automotive -E temperature grade handles under-hood environments, and the on-chip LIN-capable UART plus CCP/PWM modules drive actuators without an external transceiver's logic side. The KM-series XLP nanoWatt technology keeps quiescent current in the microamp range during key-off sleep, critical for preserving standby battery life. 16 KB Flash accommodates LIN stacks and basic diagnostics, while 1 KB SRAM is enough for message buffers and event scheduling.
推荐
Battery-Powered IoT Edge Sensors
For wireless sensor nodes powered by coin cells or 2xAA batteries, the PIC24FV16KM104-E/PT's nanoWatt XLP modes deliver sleep currents in the microamp range while retaining RAM and interrupt logic, enabling multi-year battery life. The 2.0V-5.5V input range lets the same PCB work from a single lithium cell (3.0V nominal) or 2xAA (3.0V) without rework, and the 12-bit ADC with up to 22 channels directly digitizes thermistor, photodiode, and strain-gauge signals. The CLC configurable logic cell can wake the core on analog threshold crossings, reducing firmware overhead. 16 KB Flash fits basic LoRaWAN/BLE host stacks, and 512 bytes EEPROM stores calibration constants.
推荐
Portable Medical Devices
In portable medical devices such as pulse oximeters, single-lead ECG patches, and electronic thermometers, the PIC24FV16KM104-E/PT provides IEC 62304-friendly deterministic interrupt latency, a 12-bit ADC for biosignal acquisition, and low-power modes that extend battery life on coin cells. The -E temperature grade supports storage and operational ranges required by medical device standards. The PIC24FV wide-voltage input simplifies single-cell Li-ion (3.7V) or 2xAAA (3.0V) operation without external regulators. Hardware CCP/PWM modules can drive LED pulse stacks for SpO2 measurement without software bit-banging.
推荐
Industrial Control & HMI
For industrial control panels and human-machine interfaces, the PIC24FV16KM104-E/PT integrates the peripherals needed for keypad scanning, LED/PWM feedback, and isolated UART links to a master PLC. The wide 2.0V-5.5V input tolerates 24V industrial rails after a front-end regulator, and the -40°C to +125°C -E temperature grade handles factory floor environments. The configurable logic cell offloads encoder quadrature decoding and PWM generation from the CPU, freeing cycles for the communication stack. 37 GPIO on the 44-TQFP accommodate 4x4 keypads plus status LEDs without an I/O expander.
推荐
USB Consumer Peripherals
In USB human-interface devices such as keyboards, mice, and consumer peripherals, the PIC24FV16KM104-E/PT (paired with an external USB FS transceiver such as the MCP2210 or USB3300) handles HID descriptor parsing and report generation. The 32 MIPS core comfortably runs HID class drivers, and 16 KB Flash accommodates composite HID stacks plus vendor-specific report formats. The wide-voltage 2.0V-5.5V input simplifies bus-powered designs where the 5V VBUS feeds the MCU directly after a small LDO. The 12-bit ADC can monitor battery voltage on wireless peripherals.
推荐
Motor Control & PWM Drivers
For small brushed DC, stepper, and BLDC motor control subsystems in consumer and industrial products, the PIC24FV16KM104-E/PT provides multiple 16-bit Capture/Compare/PWM (MCCP/SCCP) outputs that drive MOSFET gate drivers directly. The 32 MIPS core executes field-oriented control loops at sufficient rates for small BLDCs, and the 12-bit ADC with up to 22 channels reads back phase currents and bus voltage. The CLC module generates complementary PWM with deadband insertion, eliminating software overhead. The automotive -E range supports under-hood and outdoor industrial deployments.
推荐
Home & Building Automation
In smart-home hubs, thermostat controllers, and building automation peripherals, the PIC24FV16KM104-E/PT integrates interfaces, PWM, and ADC needed to sense temperature/humidity and drive triac-controlled loads via optoisolators. The wide 2.0V-5.5V input supports both battery-powered thermostats and 24VAC HVAC systems after rectification. The CLC module implements simple hysteresis controllers without firmware intervention, and the nanoWatt XLP mode keeps idle power below energy-star thresholds. 16 KB Flash fits Matter-over-Thread host stacks or Zigbee HA application profiles.

设计说明
The PIC24FV16KM104-E/PT supports 2.0V-5.5V VDD but draws significantly more current at higher voltages due to PIC core bias scaling. Estimated: at 32 MHz and 5.0V VDD, active current is approximately 8 mA; at 3.3V the same workload drops to roughly 5 mA. Place a 1 µF ceramic decoupling capacitor close to each VDD/VSS pin pair, and a bulk 10 µF tantalum or ceramic on the main rail. Use the XLP sleep mode with the on-chip Low-Power RTCC for product ID, keep the core in Sleep and wake on CLC threshold crossing to extend battery life.
Route the ICSP programming pins (RB6/ICSPCLK, RB7/ICSPDAT) to a header or test pad for in-circuit firmware upgrades - do not gate them behind a buffer. The VDDCORE pin (pin 41 on the 44-TQFP) requires a 470 nF ceramic capacitor to VSS, placed within 5 mm of the pin. Keep the 32 kHz secondary oscillator traces short and guarded to avoid coupling digital switching noise into the low-power wake-up path.
Estimated: at 32 MHz the PIC24F core harmonics fall in the 96-128 MHz range, so the OSC1/OSC2 traces should be no longer than 5 mm and surrounded by a ground pour to limit EMI. Place analog input traces (ANx on pins 1-8 of the 44-TQFP) away from PWM outputs to minimize ADC switching noise coupling. Use a star-ground topology at the VSS pin nearest the MCU to separate analog and digital returns.
Do not exceed 5.5V on any pin, including the MCLR reset pin. The MCLR pin requires a 10 kΩ pull-up to VDD and a 100 nF capacitor to VSS for reliable reset; omitting the capacitor can cause spurious resets during inrush. When migrating code from a PIC24FJ variant, verify the wide-voltage analog parameters because the PIC24FV-spec variants have different ADC gain error vs. 5V. Use the MCCB code generator inside MPLAB X to avoid manual register errors.
For LIN bus implementations, the LIN spec requires a slew-rate-controlled transceiver; the on-chip UART is not LIN-compliant by itself, so use an external MCP2021A or TJA1027 transceiver. The CCP/PWM outputs can drive small MOSFET gates directly but require gate-resistance series oxide of ~5-100 Ω to dampen ringing when driving cables longer than 50 mm. Keep PWM traces matched-length within 2 mm if used in complementary pairs.
