PIC24FJ128GL408-E/PT 概要
The PIC24FJ GL4 family of low-power 16-bit microcontrollers from Microchip combines a MIPS-modified Harvard architecture with a wide peripheral set for human-machine interface and connected embedded designs. The integrated LCD driver supports up to 480 segments, while dual-partition Flash enables real-time Over-The-Air (OTA) firmware updates and EEPROM emulation without external storage. Full-speed USB 2.0 device/host/OTG support, combined with up to 32 KB RAM, makes the family well suited to connected sensor and display applications.
Key features of this variant include 128 KB ECC Flash, 32 KB SRAM, an 8 MHz internal RC oscillator (with PLL), an integrated segmented LCD controller, up to 69 general-purpose I/O pins, and Core Independent Peripherals such as Configurable Logic Cells (CLC), Multiple Capture/Compare/PWM, and a 12-bit ADC. The 'E' suffix designates the extended temperature grade (-40C to +125C) and the /PT suffix denotes the 80-pin TQFP (12x12 mm) package.
Typical applications include low-power IoT sensor nodes with LCD displays, industrial HMI panels, USB-connected data loggers, smart meters with integrated segmented displays, medical handhelds requiring low-power sleep modes, and consumer appliances with graphical segmented LCD interfaces. The combination of integrated LCD, USB and ECC Flash reduces BOM and PCB area for cost-sensitive UI products.
When designing with this device, ensure that the USB VBUS pin is properly decoupled, that the segmented LCD bias network is sized for the chosen panel, and that the dual-partition Flash flow is configured in the linker. Using Microchip's MPLAB X IDE with the XC16 compiler and the MPLAB Code Configurator (MCC) plug-in streamlines peripheral setup.

主な用途
PIC24FJ128GL408-E/PT の用途: 6 件s: Industrial HMI with Segmented LCD, USB-Connected Data Logger, Smart Meter with LCD Display, Medical Handheld Device, IoT Sensor Node with Display, Consumer Appliance Control Panel.
Industrial HMI with Segmented LCD
The PIC24FJ128GL408-E/PT is built for industrial human-machine interface panels that combine an integrated segmented LCD controller with USB connectivity and ECC Flash. With 128 KB ECC Flash and 32 KB SRAM, the device can hold full USB stacks, graphics buffers, and LCD frame data simultaneously, while the 'E' temperature grade ensures reliable operation from -40C to +125C on factory floors. Up to 480 supported LCD segments enable rich multi-digit numeric displays, icon indicators, and progress bars without an external LCD driver, which saves BOM cost. The Core Independent Peripherals, including Configurable Logic Cells (CLC), can scan keypad matrices and drive display updates without CPU intervention, freeing the MIPS core for higher-level logic.

USB-Connected Data Logger
The PIC24FJ128GL408-E/PT integrates Full-Speed USB 2.0 with Device, Host, and OTG support, making it a cost-effective 16-bit MCU for tethered data loggers and instruments. The 128 KB ECC Flash stores calibration tables and event logs, while 32 KB SRAM buffers streaming data before USB transfers. Internal Core Independent Peripherals such as DMA and timers trigger ADC captures without CPU load, enabling low-noise measurements. The integrated segmented LCD can display live measurements, status icons, and unit labels, while USB carries power and data to the host PC. Compared to an external LCD driver + separate MCU architecture, the GL408 reduces BOM count, PCB area, and firmware complexity.
おすすめ
Smart Meter with LCD Display
The PIC24FJ128GL408-E/PT is well suited to smart utility meters that require a long-life LCD and robust flash integrity. The integrated segmented LCD controller directly drives glass panels showing consumption digits, status icons, and radio-link indicators. ECC Flash corrects single-bit errors automatically, ensuring the metering firmware remains reliable over a 10-15 year deployment. USB connectivity simplifies meter commissioning and firmware updates via a service tool, while the dual-partition Flash layout enables real-time OTA updates without external EEPROM. Low-power sleep modes extend battery life on battery-backed meters, and the wide 2.0-3.6 V operating range accommodates single-cell lithium and regulated 3.3 V rails.
おすすめ
Medical Handheld Device
The PIC24FJ128GL408-E/PT fits portable medical handhelds such as patient monitors and diagnostic readers that demand low power consumption, an integrated segmented LCD for clear readouts, and USB for charging or data sync. The 16 MIPS performance comfortably handles sensor acquisition, filtering, and LCD refresh duties, while the 32 KB SRAM supports real-time waveform buffers. Core Independent Peripherals can scan capacitive touch keys without waking the CPU, reducing average power consumption for battery-operated medical devices. The 'E' temperature grade supports devices stored or operated in cold environments (e.g., refrigeration units for vaccines). USB Full-Speed simplifies tethered charging and firmware updates in the field.
おすすめ
IoT Sensor Node with Display
The PIC24FJ128GL408-E/PT is ideal for IoT sensor nodes that need to display local readings on a segmented LCD while connecting to a USB host or wireless bridge. The integrated LCD controller eliminates the need for a separate display MCU, and the 128 KB Flash with ECC supports stack libraries such as USB, Modbus, and sensor drivers. Low-power sleep modes let the device operate for months on battery, waking only to capture sensor data and refresh the LCD. CLC and other Core Independent Peripherals can perform sensor sampling and threshold detection without CPU intervention, dramatically reducing average current draw. The 'E' grade supports outdoor deployments with -40C to +125C operation.
おすすめ
Consumer Appliance Control Panel
The PIC24FJ128GL408-E/PT fits consumer appliance control panels such as washing machines, microwave ovens, and induction cooktops that use segmented LCD or LED displays plus USB service ports. The integrated LCD driver can show cycle status, error codes, and timer countdowns directly, while USB enables firmware updates in the field through a service tool. Core Independent Peripherals drive PWM outputs for motor or heating element control in parallel with UI updates, offloading the CPU. The wide 2.0-3.6 V supply range accommodates direct 3.3 V regulated rails, and the 'E' grade ensures operation near heat sources like ovens or cooktops. Compared with discrete MCU + LCD driver designs, the GL408 reduces BOM and simplifies firmware maintenance across product variants.

設計ノート
The PIC24FJ128GL408-E/PT operates from 2.0 V to 3.6 V. Decouple VDD/VSS pairs with 100 nF ceramic capacitors placed within 5 mm of each supply pin, and add a bulk 4.7 uF tantalum or ceramic capacitor near the device. The internal voltage regulator requires a 10 uF decoupling cap on the VDDIO/VDDCORE pin. For battery designs, route the LCD bias and RTC supply on separate pins to minimize current draw in low-power sleep modes.
Route the 32 MHz system clock trace symmetrically with a ground reference to avoid reflections. Keep the LCD segment traces short and grouped by common signal layers, and shield analog traces with ground. The integrated LCD controller drives up to 480 segments; a careful stackup (4-layer PCB with continuous ground plane under the LCD area) reduces cross-coupling and improves contrast stability. Use the Microchip PIC24FJ GL4 Family Reference Manual section on LCD pin mapping for the correct segment-to-pin allocation in MPLAB X.
Estimated: Configuring the dual-partition Flash requires defining boot, swap, and protection bits in the MPLAB X project properties; failing to enable ECC interrupts can mask single-bit corrections. The integrated USB module requires precise 48 MHz clocking - if the PLL drifts, USB enumeration fails. Do not reuse the VBUS sense pin as a regular GPIO on battery-only designs. The 'E' grade supports -40C to +125C, but USB Full-Speed is only guaranteed over -40C to +85C. Verify with the datasheet electrical characteristics table when designing for full industrial temperature.
