PIC24FJ128GU410-I/PT - 16-Bit MCU 128KB Flash USB LCD 100-TQFP
MPN: PIC24FJ128GU410-I/PT ✓ פעילPIC24FJ128GU410-I/PT סקירה
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/SRAM), and I/O peripherals onto one die. The PIC24F family sits between the 8-bit PIC16/PIC18 and the 32-bit PIC32 in Microchip's portfolio, providing 16 MIPS performance with low power consumption for embedded control. Within this taxonomy, PIC24FJ128GU410 belongs to the XLP "GU4" subfamily, which adds 512 KB dual-partition Flash with Over-The-Air (OTA) bootloading and EEPROM emulation - the highest-memory tier of the GU4 series.
Key features include 128 KB ECC Flash with dual partition support, 32 KB SRAM, full-speed USB 2.0 device/host/OTG, hardware real-time clock and calendar (RTCC), a 4x40 segmented LCD controller, multiple UART/SPI/I2C peripherals, and 10-bit ADC. The dual-partition Flash allows safe firmware upgrades in the field: while one partition runs application code, the other can be reprogrammed, then control swaps. This makes the GU4 family uniquely suited to connected, serviceable products where firmware must be updated without bricking the unit.
Typical applications include industrial sensor hubs with LCD readouts, USB-connected medical devices, home appliances with user interfaces, metering and measurement instrumentation, and IoT edge nodes with secure OTA firmware delivery. The integrated USB and LCD eliminate external bridge chips, reducing BOM cost and PCB footprint in human-interface designs.
When designing with this part, observe the 3.3V core supply requirement (typical operating range 2.0-3.6V) and provide a 32.768 kHz crystal for RTCC accuracy if calendar functionality is required. Route the USB D+/D- lines as a 90-ohm differential pair and decouple all power pins with 100 nF ceramic capacitors placed within 3 mm of each VDD/VSS pin pair.

יישומים טיפוסיים
PIC24FJ128GU410-I/PT מתאים עבור 6 יישוםs: Industrial USB Sensor Hub, Medical Infusion Pump with LCD, Home Appliance User Interface, Smart Meter with USB Diagnostics Port, IoT Edge Node with OTA Firmware, USB Barcode Scanner / POS Terminal.
Industrial USB Sensor Hub
The PIC24FJ128GU410-I/PT fits industrial USB sensor hubs because its integrated full-speed USB controller eliminates external bridge chips while the 16 MIPS performance handles multi-channel sensor sampling. Place the MCU as the USB device controller on a 90-ohm differential pair for D+/D-, with the 32 KB RAM buffering high-rate ADC streams. The XLP deep-sleep current under 1 uA enables battery-backed operation between USB host sessions, suiting portable calibration tools. The dual-partition Flash allows safe field firmware updates when sensor algorithms change.
מומלץ
Medical Infusion Pump with LCD
The PIC24FJ128GU410-I/PT suits medical infusion pumps because the integrated 4x40 LCD controller drives the dosage display directly while the RTCC hardware block provides tamper-resistant time-of-day logging. Run the MCU at 32 MHz to handle pump stepper motor PWM and pressure-sensor ADC sampling in real time. The 128 KB ECC Flash holds the safety-critical control algorithm with single-bit error correction per Microchip datasheet - critical for IEC 62304 medical device firmware classification. Dual-partition OTA enables certified field firmware updates without service interruption.
מומלץ
Home Appliance User Interface
The PIC24FJ128GU410-I/PT fits home appliance HMIs such as washing machines and induction cooktops because the on-chip LCD controller drives 7-segment or character displays while the USB allows factory programming and field diagnostics. Run at 16 MIPS to manage touch-button scanning via the CTMU peripheral and triac zero-cross timing for heater control. The XLP sleep modes drop consumption to microampere range during standby, meeting ENERGY STAR appliance idle budgets per the Microchip PIC24F XLP datasheet. Industrial -40C to +85C rating covers appliance thermal environments.
מומלץ
Smart Meter with USB Diagnostics Port
The PIC24FJ128GU410-I/PT supports smart electricity meters with USB diagnostics because the integrated LCD drives the consumption readout while USB enables field engineer access to logging data. The 32 KB RAM buffers metrology calculations (RMS, power factor) while 128 KB Flash stores tariffs and history. Run the RTCC from a 32.768 kHz crystal for time-of-use billing accuracy. Dual-partition OTA allows utility firmware updates over the network without rolling a truck, per the Microchip PIC24FJ GU4 family OTA documentation.
מומלץ
IoT Edge Node with OTA Firmware
The PIC24FJ128GU410-I/PT serves IoT edge nodes because its dual-partition Flash with OTA bootloading is the defining feature for securely updatable connected devices. Run one partition as the application while the other receives new firmware over USB or wireless bridge, then atomically swap per Microchip's FFBOOT bootloader. XLP current under 1 uA in sleep extends battery life to years when the node wakes periodically. The 16 MIPS handles edge analytics before forwarding aggregated data to the cloud.
מומלץ
USB Barcode Scanner / POS Terminal
The PIC24FJ128GU410-I/PT fits USB barcode scanners and POS terminals because full-speed USB device mode plugs directly into a host while the LCD controller drives a small customer-facing display. The 32 KB RAM buffers scanned barcode streams for protocol conversion (HID, CDC, or vendor-class). Run at 32 MHz for 16 MIPS decode throughput per Microchip documentation. Dual-partition OTA enables remote firmware updates when barcode symbology libraries expand - critical for retail deployments across thousands of terminals.

הערות תכנון
Decouple every VDD pin with a 100 nF X7R ceramic capacitor within 3 mm of the pin, plus a bulk 10 uF tantalum or ceramic at the regulator output. Estimated: at 32 MHz/16 MIPS full active current around 15 mA, the bulk capacitor prevents supply droop during USB enumeration bursts. The PIC24FJ128GU410 has multiple VDD/VSS pin pairs that MUST each be decoupled - leaving any pair un-decoupled can cause erratic operation or USB enumeration failure.
Route the USB D+ and D- lines as a 90-ohm differential pair with continuous ground reference beneath, matching the USB 2.0 full-speed specification. Maximum trace length should be under 50 mm and the pair must be length-matched within 2 mm. Place the 27 MHz primary oscillator crystal within 5 mm of OSC1/OSC2 with a ground guard ring to prevent coupling USB harmonics into the clock.
Do not omit the MCLR pull-up resistor (typically 10 kohm to VDD); the PIC24FJ128GU410 will not start without it. Do not confuse TQFP-100 (PT) with TQFP-64 (PT) variants - the /PT suffix is reused across pin counts in the Microchip ordering system. Always verify the exact pin count in the datasheet header before ordering the PCB footprint.
Take advantage of the deep-sleep mode (under 1 uA per Microchip XLP datasheet) by configuring unused pins as outputs driving low and disabling all peripherals via PMD registers before entering Sleep. The RTCC can wake the MCU on alarm - route the SOSC crystal (32.768 kHz) to dedicated SOSCI/SOSCO pins (per datasheet pinout) to maintain timekeeping while the main oscillator is stopped.
