PIC24FJ128GL410T-I/PT - 16-Bit MCU, 128KB Flash, LCD, USB | Microchip
MPN: PIC24FJ128GL410T-I/PT ✓ نشطPIC24FJ128GL410T-I/PT نظرة عامة
A PIC microcontroller (MCU) is a compact, self-contained computer-on-a-chip that integrates a CPU core, non-volatile program memory (Flash), volatile working memory (RAM), and a rich set of peripheral interfaces (timers, ADC, communication buses, GPIO) into a single semiconductor device. Within the broader taxonomy, the PIC24FJ family belongs to the 16-bit microcontroller category, which sits between 8-bit MCUs (such as the PIC16 and PIC18 families) and 32-bit MCUs (such as the PIC32MZ and Cortex-M4). 16-bit MCUs are typically selected when engineers need higher computational throughput than 8-bit parts can deliver, but do not yet require the memory footprints and complexity of 32-bit architectures.
Key features of the PIC24FJ128GL410T-I/PT include 128KB of ECC Flash supporting Live Update / Dual Partition for bootloading and OTA firmware delivery, 32KB SRAM, a 4KB Instruction Cache, hardware crypto acceleration options in the broader family, a 10-bit ADC with up to 1 Msps, and a segmented LCD controller capable of driving up to 384 segments. The TQFP-100 package exposes extensive GPIO, USB, I2C, SPI, UART, and CAN connectivity, while the low-power Run, Idle, and Sleep modes enable battery-friendly operation. On-chip Core Independent Peripherals such as Configurable Logic Cells, multiple PWM outputs, and CTMU allow designers to offload tasks from the CPU.
The architecture uses a 16-bit modified Harvard CPU with deterministic interrupt response, an internal 8 MHz Fast RC oscillator (with PLL to 32 MHz), and rich power management features including a Low-Power Brown-Out Reset (LPBOR) and a Windowed Watchdog Timer (WWDT). The dual-partition flash design permits one partition to run while the other is updated, enabling safe firmware upgrades without service interruption.
Typical applications include industrial human-machine interfaces (HMI) with LCD display, USB-connected consumer devices, secure IoT edge nodes requiring OTA update capability, low-power medical devices, automotive body and instrument clusters, and battery-powered metering systems. The integrated USB makes the part particularly attractive for tethered diagnostics and tethered firmware update scenarios.
When designing with this part, ensure the USB bus is properly terminated with the recommended 33 ohm series resistors and that the segmented LCD bias network uses Microchip-recommended charge-pump or resistor-ladder configurations. Decoupling should include 100nF ceramic capacitors close to each VDD/VSS pair and a bulk 4.7uF to 10uF capacitor near the main supply pin.

Industrial Human-Machine Interface (HMI) with LCD
The PIC24FJ128GL410T-I/PT is purpose-built for industrial HMI panels with segmented LCDs, where its on-chip segmented LCD driver supports up to 384 segments, eliminating an external driver IC. The 32KB SRAM comfortably stores frame buffers and menu state, while the 32MHz/16 MIPS core drives RTOS-style menu logic in real time. Its 128KB ECC Flash with Dual Partition enables safe OTA firmware updates from the field without halting the panel.

USB-Connected Consumer Devices
The integrated USB 2.0 full-speed OTG controller makes the PIC24FJ128GL410T-I/PT ideal for USB peripherals, including HID input devices, USB-to-UART bridges, and consumer accessories that need a tethered firmware update path. The internal USB transceiver removes the need for an external PHY, and 32KB SRAM supports HID ring buffers or vendor-class transfer queues without dropping frames.

Low-Power Medical Instruments
Medical devices such as blood-glucose meters, infusion monitors, and portable diagnostic tools benefit from the PIC24FJ128GL410T-I/PT segmented LCD interface for direct numeric display, plus XLP-class sleep current below 1 uA for multi-month battery life. The 10-bit 1 Msps ADC supports sensor sampling, while Core Independent Peripherals (CIPs) offload repetitive measurement timing from the CPU for deterministic, low-jitter acquisition.

Battery-Powered IoT Edge Nodes with OTA
IoT edge nodes that must receive secure Over-The-Air firmware updates benefit from the PIC24FJ128GL410T-I/PT Dual Partition Flash: one partition runs the application while the other is reprogrammed, eliminating downtime during OTA. The 32KB SRAM handles TLS-like packet buffers and small MQTT messages. Deep Sleep with RTCC keeps idle current low for solar or coin-cell powered deployments.

Automotive Body and Instrument Cluster Displays
Cluster displays, climate-control panels, and body controllers in automotive environments use the PIC24FJ128GL410T-I/PT to drive segmented LCD indicators while supporting CAN/LIN communication. Although the 'I' grade is -40C to +85C and not AEC-Q100 qualified, the part is widely used in non-safety automotive body applications where industrial temperature range is acceptable. The 32KB SRAM supports segmented LCD refresh with 100Hz update rate.

Smart Energy Meters and Utility Displays
Single-phase and polyphase energy meters use the PIC24FJ128GL410T-I/PT to drive multi-digit segmented LCD readouts, sample voltage/current, and compute billing data. The 10-bit ADC interfaces with shunt or CT sensors, while the LCD driver produces glass-LCD digits directly. The 32KB SRAM buffers instantaneous and accumulated energy values, and USB allows utility technicians to perform field diagnostics.

Portable Test and Measurement Equipment
Handheld oscilloscopes, multimeters, and sensor calibrators integrate the PIC24FJ128GL410T-I/PT as a USB-tethered data logger with on-screen segmented LCD. The USB OTG port streams measurement data to a host PC, while the segmented LCD shows live readings without needing an external driver. 128KB Flash stores calibration constants, look-up tables, and user-defined test sequences.

دليل الاختيار
Pick the PIC24FJ256GL410T-I/PT instead if you need 256KB Flash for larger firmware images, or the PIC24FJ64GL410T-I/PT if you need only 64KB Flash for cost-sensitive designs. Choose the PIC24FJ128GB410T-I/PT for hardware cryptographic acceleration and XLP, but note that you lose Dual Partition OTA. For AEC-Q100 automotive-grade requirements, look at the PIC24FJ128GA410T-I/PT family instead, which provides automotive qualification at the cost of smaller SRAM.

ملاحظات التصميم
Place a 100nF ceramic decoupling capacitor within 3mm of every VDD/VSS pair on the TQFP-100 package, and add a bulk 4.7uF to 10uF low-ESR capacitor near the main VDD pin. The analog AVDD/AVSS pair must have a dedicated 100nF capacitor and ferrite bead or 10 ohm resistor for noise isolation from digital VDD. USB VUSB requires a 100nF bypass and a 1k pull-down to D- if using bus-powered mode.
Route the USB D+ and D- lines as a 90 ohm differential pair with matched lengths within 150 mils, and keep them away from switching signals and oscillators to meet USB 2.0 FS signal integrity. Place the 33 ohm series termination resistors close to the PIC24FJ pins. The segmented LCD segment and common traces should be guarded by ground traces to minimize cross-coupling, and the bias charge-pump capacitor must be ceramic.
Estimated: do not exceed 3.6V on any VDD pin - the PIC24FJ is a 3.3V part and absolute-maximum stress will permanently damage the on-chip Flash and USB transceiver. The MCLR reset pin must use the recommended 10k pull-up and decoupling to avoid spurious resets. When using Dual Partition OTA, ensure the boot configuration words select the correct default partition to avoid bootloader lock-out after a failed update.
