PIC24FJ32GA104-I/ML - 16-Bit 32KB Flash MCU, 44-QFN | Microchip
MPN: PIC24FJ32GA104-I/ML ✓ Hoạt độngPIC24FJ32GA104-I/ML Tóm tắt
A 16-bit microcontroller (MCU) is a single-chip computer with a 16-bit data path, instruction word, and ALU, sitting in the hierarchy: microcontroller -> embedded controller -> semiconductor. The PIC24F family uses a Modified Harvard architecture with 16-bit instructions and 24-bit instruction words, optimized for C compiler efficiency and signal processing. This positions it between 8-bit MCUs (PIC16, AVR) and 32-bit MCUs (PIC32, ARM Cortex-M), offering a balance of compute throughput, peripheral integration, and low power consumption.
Key features include up to 16 MIPS performance, single-cycle execution, 16 x 16 hardware multiply, 32-bit / 16-bit hardware divider, a C-compiler-optimized instruction set, and the nanoWatt XLP sleep modes that allow standby currents in the microamp range. The 44-QFN package integrates peripherals such as multiple UART/SPI/I2C interfaces, 12-bit ADC, real-time clock, and up to 33 digital I/O pins.
Typical applications include portable medical devices, low-power IoT sensor nodes, industrial control with LCD display, battery-powered data loggers, and consumer products requiring extended battery life. The wide 2.0V to 3.6V operating range supports direct Li-ion battery connection with on-chip regulation.
When designing with this part, allocate PCB thermal relief to the exposed pad (EP) on the 44-QFN for proper ground connectivity and heat dissipation. Use Microchip's MPLAB X IDE with the XC16 compiler and consider the Explorer 16/32 development board for prototyping with compatible Processor Plug-In Modules.

Ứng dụng tiêu biểu
PIC24FJ32GA104-I/ML phù hợp cho 6 Áp dụngs: Portable Medical Devices, Low-Power IoT Sensor Nodes, Industrial Control with LCD Display, Battery-Powered Data Loggers, Consumer Appliance Control, Educational and Prototyping Platforms.
Portable Medical Devices
The PIC24FJ32GA104-I/ML fits portable medical applications because of its nanoWatt XLP technology delivering microamp-range sleep currents, enabling multi-year battery life on a single coin cell. With 32 KB Flash and 8 KB RAM it can run sensor-fusion algorithms, blood-pressure or pulse-oximetry front-end control, and BLE link management via UART. The 2.0-3.6 V operating range allows direct Li-ion or 2xAA battery connection without external LDO regulation.
Được đề xuất
Low-Power IoT Sensor Nodes
The PIC24FJ32GA104-I/ML is ideal for IoT sensor hubs because its nanoWatt XLP sleep currents below 1 uA allow the node to wake only on sensor events, transmitting over UART-attached BLE or Sub-GHz radios. At 16 MIPS the core can execute sensor-fusion and AES-128 encryption in real time. The 33 I/O pins support multiple I2C/SPI sensor breakouts and the 12-bit ADC handles analog sensors directly without external signal conditioning.
Được đề xuất
Industrial Control with LCD Display
The PIC24FJ32GA104-I/ML suits industrial HMI controllers because it integrates segmented LCD driver support and enough I/O to scan keypads while driving displays. Industrial temperature grade (-40C to +85C) supports factory floor deployment. The hardware 16x16 multiplier and 32/16 divider accelerate PID loop math at sub-millisecond periods, while 8 KB RAM holds control variables and LCD buffer memory without external expansion.
Được đề xuất
Battery-Powered Data Loggers
The PIC24FJ32GA104-I/ML is well suited to battery data loggers because the XLP sleep modes combined with the real-time clock calendar enable sample-and-store operation at intervals of seconds to hours while consuming microamp average current. The 32 KB Flash can hold thousands of timestamped samples with compression, and the 12-bit ADC digitizes sensor data at rates up to 200 ksps for transient event capture. SPI interface supports external Flash for extended logging capacity.
Được đề xuất
Consumer Appliance Control
The PIC24FJ32GA104-I/ML fits cost-sensitive consumer appliances such as coffee makers, washing machines, and air purifiers because it integrates UART, SPI, I2C, and PWM peripherals in a single 44-QFN at sub-$3 price points. The 16 MIPS performance handles user-interface state machines and motor-control loops. RoHS compliance and the wide 2.0-3.6 V range simplify global deployment with universal power supply designs.
Được đề xuất
Educational and Prototyping Platforms
The PIC24FJ32GA104-I/ML is widely used in university curricula and hobbyist prototyping because of its mature MPLAB X IDE ecosystem, free XC16 compiler, and the Explorer 16/32 development board with matching Processor Plug-In Modules (PIMs). 32 KB Flash and 8 KB RAM provide adequate headroom for teaching RTOS concepts, peripheral drivers, and signal processing. C-compiler-optimized instruction set accelerates the learning curve from assembly to C development.

Ghi chú thiết kế
The 44-QFN exposed thermal pad (EP) MUST be soldered to the PCB ground plane for both electrical reference and thermal dissipation. Per Microchip QFN layout guidelines, place a 9x9 array of 0.3 mm thermal vias on a 1.2 mm pitch directly under the EP, with the vias tented or filled to prevent solder wicking. Without proper EP soldering, the part may exhibit erratic operation and reduced thermal performance.
Place a 10 uF bulk capacitor and a 0.1 uF decoupling capacitor as close as possible to the VDD pin (pin 13). Add a separate 0.1 uF cap on the AVDD pin (if used for ADC reference) to reduce digital switching noise coupling into analog measurements. The PIC24FJ32GA104 power-on reset threshold is approximately 1.8 V; ensure VDD ramp time is <50 ms to guarantee clean startup per the datasheet BOR specification.
Do not leave the MCLR pin (pin 43) floating - tie it to VDD through a 10 kohm pull-up resistor. For ICSP programming, add a 10 kohm series resistor and a diode to allow in-circuit debug without interfering with normal operation. Also note that the 'I' suffix denotes industrial temperature grade (-40C to +85C); for AEC-Q100 automotive applications choose a PIC24FJxxGA1xx-Q1 variant instead.
