PIC24FJ128GA306-I/MR Übersicht
A microcontroller (MCU) is an integrated circuit that combines a CPU, non-volatile program memory (typically Flash), RAM, and a rich set of peripherals (timers, communication controllers, ADCs, GPIO) on a single die. The PIC24F family sits in Microchip's 16-bit MCU portfolio, positioned between 8-bit PIC16/PIC18 devices and the higher-end dsPIC/PIC32 lines, offering a balance of compute performance, code density, and ultra-low power consumption. XLP technology allows battery-powered products to extend operating life into the multi-year range.
Key features of this part include 128 KB Flash (43K x 24 instruction words), 32 MHz operation from an internal oscillator with PLL, integrated LCD driver, multiple serial interfaces (UART, SPI, I2C), a 10-bit ADC, and nanoWatt XLP modes that drop active current to single-digit microampere levels. The -I grade ensures the device operates across industrial temperature ranges for factory and outdoor equipment.
The PIC24FJ128GA306 uses a 16-bit modified Harvard architecture with a hardware multiplier and a deterministic interrupt controller, enabling predictable response times for real-time control loops. The 128 KB Flash supports in-circuit self-programming, which is critical for bootloader-based field updates. Internal RC oscillators minimize external component count, reducing BOM cost and PCB area in space-constrained designs.
Typical applications include battery-powered IoT sensor nodes, portable medical monitors, industrial control HMI panels with LCD readouts, eMeter/energy-harvesting devices, and consumer appliances that require LCD display plus low standby current. Designers typically pair this MCU with a low-quiescent LDO and an SPI NOR Flash for data logging.
When designing with the -I/MR variant, ensure the 9x9 mm VQFN exposed pad is soldered to a sufficient copper pour for thermal dissipation. The LCD segment pins are multiplexed with GPIO - unused segments can be repurposed as digital I/O if the LCD is not used, but pin remapping must follow the device pinout table.

Typische Anwendungen
PIC24FJ128GA306-I/MR ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Node, Industrial HMI Panel with LCD Readout, Portable Medical Monitor, Smart Energy Meter / e-Meter, Consumer Appliance Controller, Automotive Body Electronics (Non-Safety).
Battery-Powered IoT Sensor Node
The PIC24FJ128GA306-I/MR's 340 nA XLP sleep current and 32 MHz active throughput suit unattended sensor nodes that wake briefly to transmit, then return to deep sleep. Its 128 KB Flash accommodates a TCP/IP or LoRaWAN stack with local buffering, and the integrated 10-bit ADC handles analog sensor front-ends directly. Paired with a low-Iq LDO, the node achieves multi-year coin-cell life on a single CR2032.
Empfohlen
Industrial HMI Panel with LCD Readout
The integrated LCD controller eliminates an external display driver chip, reducing BOM cost and PCB area for industrial control panels. With 128 KB Flash, the device can host a graphics library plus Modbus RTU master stack. The -40C to +85C industrial temperature grade ensures reliable operation in factory floors. Segment count supports typical 7-segment or dot-matrix numeric displays.
Empfohlen
Portable Medical Monitor
The combination of nanoWatt XLP modes, 32 MHz compute headroom for DSP-style signal processing, and 128 KB Flash for waveform buffers makes this MCU a fit for battery-powered pulse oximeters and glucose meters. The LCD controller drives a segmented display without an external driver. Industrial temperature grade accommodates typical clinical and home-use environments.
Empfohlen
Smart Energy Meter / e-Meter
Energy meters demand accurate ADC sampling plus long battery-backed RTC retention, both of which the PIC24FJ128GA306 family supports. The XLP sleep with RAM retention at 340 nA preserves metering logs during power outages. The 128 KB Flash fits a metering protocol stack plus tariff logic. The /MR QFN package provides a low-profile footprint for in-meter PCBAs.
Empfohlen
Consumer Appliance Controller
Washing machines, coffee makers, and induction cooktops need a reliable 16-bit MCU to manage motor control, user interfaces, and safety timers. The integrated LCD driver supports segment displays for time/temperature readouts. The industrial temperature grade handles under-cabinet thermal stress. Pin count (64) provides sufficient GPIO for relays, sensors, and keypad matrix scanning.
Empfohlen
Automotive Body Electronics (Non-Safety)
While the -I grade targets industrial use, body modules like climate control panels, mirror adjusters, and ambient lighting benefit from the LCD controller and XLP sleep. Designers needing AEC-Q100 must move to the automotive-qualified VAO suffix variant of the same die. The 64-pin VQFN footprint allows compact module PCBs with high thermal conductivity via the exposed pad.

Wichtigste Unterscheidungsmerkmale
- Integrated LCD controller eliminates external driver (vs. PIC24FJ128DA106-I/MR (no LCD controller))
- Drop-in 256 KB upgrade path on same footprint (vs. PIC24FJ128GA310-I/MR)
- 340 nA typical XLP sleep with RAM retention (vs. PIC24FJ128GA306-I/PT (same die, different package))
Designhinweise
The 64-pin VQFN (9x9 mm) package has an exposed thermal pad that MUST be soldered to a sufficient copper pour on the PCB to meet the device's thermal resistance specification. Estimated: with the EP connected to a 1 sq-inch 2-oz copper pour on a 4-layer board, theta_JA drops to roughly 25 C/W. Without the EP soldered, junction-to-ambient thermal resistance rises dramatically and the device may thermal-throttle at moderate loads.
Place decoupling capacitors (100 nF ceramic plus 10 uF bulk) as close as possible to each VDD/VSS pair. The secondary 32.768 kHz crystal for the low-power RTC should be placed within 5 mm of the SOSC1/SOSC2 pins with a grounded guard ring to reduce noise injection. Keep the MCLR pull-up resistor within 5 mm of the MCLR pin and avoid routing high-frequency signals near it.
Do not assume any PIC24F can be a drop-in replacement across the GA306/GA310 family; the 64-pin /MR package shares a common footprint but pin functions on RB5/RB6 differ between I2C and GPIO modes. Always cross-check the device pinout table in the 30015714 datasheet before PCB reuse. Also, the XLP sleep current of 340 nA is typical at room temperature - at +85C the maximum figure can be 50x greater, impacting battery-life calculations for outdoor deployments.
Estimated: at 32 MHz active, the core draws roughly 15 mA from a 3.3 V supply. Pair the MCU with an LDO such as the MCP1700 (1.6 uA quiescent) to avoid burning idle current in the regulator itself. For battery-only designs, a load switch on the LCD charge pump can be turned off in deep sleep to eliminate the LCD bias current entirely.
Compliance-Informationen
RoHS and lead-free per Microchip product page and distributor listings. Not AEC-Q100 qualified in the -I/MR suffix; automotive designs require the VAO-qualified variant. REACH and conflict-minerals compliance follows Microchip standard policy.
