PIC24FJ256GU410-I/PT - 256KB Flash 16-bit MCU | Microchip
MPN: PIC24FJ256GU410-I/PT ✓ Hoạt độngPIC24FJ256GU410-I/PT Tóm tắt
A 16-bit microcontroller (MCU) is a microprocessor with a 16-bit data path that balances 8-bit simplicity with 32-bit performance, typically used in embedded systems that need moderate computational throughput, low power, and rich peripherals. The PIC24FJ family sits within Microchip's broader taxonomy of microcontrollers (MCU) and is itself a subset of the eXtreme Low Power (XLP) line, with the 'GU4' sub-family adding USB and segmented LCD support to the core PIC24F feature set.
Key features include 32 MHz (16 MIPS) operation from a 2.0-3.6V supply, 85 I/O pins, dual-partition flash supporting real-time Over-The-Air (OTA) updates and EEPROM emulation, and a hardware crypto engine (AES/DES/SHA) for secure applications. The integrated full-speed USB 2.0 controller is OTG-capable and supports both host and device roles. The LCD controller drives up to 512 segments, eliminating external display drivers for HMI designs.
Architecturally, the PIC24FJ256GU410 uses a 16-bit modified Harvard core with hardware multiply/divide, separate program and data buses, and a rich set of Core Independent Peripherals (CIPs) including configurable logic cells (CLC), multiple SCCP/SCCP+ timers, 12-bit ADC, and multiple UART/SPI/I2C serial interfaces. The XLP design achieves sub-uA sleep currents, making it well-suited to battery-powered or energy-harvesting products.
Typical applications include USB-connected HMI panels with LCD and capacitive touch, secure IoT edge nodes with OTA firmware updates, automotive body and climate control modules, medical point-of-care instruments, and industrial sensor hubs. The dual-partition flash and integrated AES engine make the part a strong fit for any product that must update firmware in the field without bricking the device.
When designing with this part, plan the pinout around the LCD segment assignments and USB D+/D- routing, because the USB transceiver pins must be impedance-matched to 90 ohms differential. The dual-partition flash requires the boot firmware to implement a verified Golden Image fallback for OTA to be reliable in production deployments.

Ứng dụng tiêu biểu
PIC24FJ256GU410-I/PT phù hợp cho 7 Áp dụngs: USB-Connected HMI Panels with LCD, Secure IoT Edge Nodes with OTA Updates, Automotive Body and Climate Control, Medical Point-of-Care Instruments, Industrial Sensor Hubs with LCD Readout, USB Peripherals: HID, CDC, and Vendor Devices, Smart Home Touch Panels.
USB-Connected HMI Panels with LCD
The PIC24FJ256GU410-I/PT's integrated full-speed USB 2.0 OTG controller, 512-segment LCD controller, and 85 I/O pins make it a single-chip solution for USB-connected HMI panels. The USB port streams data to the host while the local segment LCD displays status without an external driver. Placing 10 uF + 0.1 uF decoupling on VDD near the IC and routing USB D+/D- as a 90 ohm differential pair keeps EMI under FCC Class B limits. Compared to a discrete USB MCU + LCD driver solution, this part saves BOM cost and PCB area.

Secure IoT Edge Nodes with OTA Updates
With 256KB dual-partition flash, 32KB RAM, and a hardware AES/DES/SHA crypto engine, PIC24FJ256GU410-I/PT is well suited for secure IoT edge nodes that require Over-The-Air firmware updates. The dual-partition flash allows one half to receive new firmware while the other continues running the current image, eliminating bricking risk. The crypto engine accelerates TLS handshake and data-at-rest encryption. XLP sleep currents below 1 uA extend battery life, while the wide 2.0-3.6V VDD range supports lithium and energy-harvesting supplies.

Automotive Body and Climate Control
Automotive body controllers, HVAC panels, and instrument cluster sub-modules are a strong fit for PIC24FJ256GU410-I/PT. The AEC-Q100 qualification (per OnlineComponents listing), 256KB flash for HVAC/lighting profiles, 85 I/O for switches and PWM actuators, and hardware AES for secure diagnostic (UDS) sessions cover the typical body-electronics workload. The 2.0-3.6V supply matches automotive 12V rails with an upstream LDO. The segmented LCD controller directly drives a TN-type LCD glass without an external driver.

Medical Point-of-Care Instruments
PIC24FJ256GU410-I/PT suits handheld medical point-of-care devices such as glucose meters, pulse oximeters, and rapid diagnostic readers. The 32 KB RAM supports modest sensor-fusion algorithms, the 12-bit ADC handles analog front-end measurements, and the LCD controller drives a 4-digit 7-segment display for direct readouts. USB-OTG enables tethered data transfer to a host PC, while the XLP architecture preserves battery life. Adding medical-grade isolation (e.g., isolation barrier ICs) protects the host port and meets IEC 60601 leakage requirements.

Industrial Sensor Hubs with LCD Readout
For factory-floor sensor hubs and process instrumentation, PIC24FJ256GU410-I/PT provides 85 I/O for multi-channel analog sensor conditioning, 256 KB flash for protocol stacks (Modbus, CANOpen if external PHY added), and an LCD controller for local numeric or 14-segment status readouts. The industrial -40C to +85C temperature range suits most plant environments, and the XLP architecture lets the device sleep between samples to extend battery life in remote installations. CAN support requires an external MCP2551/PCA82C251 transceiver.

USB Peripherals: HID, CDC, and Vendor Devices
PIC24FJ256GU410-I/PT is a strong match for USB peripherals - HID input devices, CDC virtual COM ports, and custom vendor-class USB products. The full-speed USB 2.0 OTG controller eliminates external PHY cost, the 32 KB RAM holds USB endpoint buffers and application state, and the 256 KB flash accommodates USB stacks plus application code. Common examples include USB barcode scanners, USB fingerprint scanners, USB cable testers, and USB-programmable industrial controllers that need a local LCD for status.
Được đề xuất
Smart Home Touch Panels
PIC24FJ256GU410-I/PT can drive smart home wall-mounted touch panels with integrated LCD readout, multiple capacitive touch inputs, and USB or wireless connectivity via external modules. The 512-segment LCD controller is suitable for thermostat-style numeric displays; combined with CLC (Configurable Logic Cell) peripherals, capacitive touch sensing and LED dimming can be handled in hardware with minimal CPU load. The wide 2.0-3.6V VDD range lets the design share a battery or AC-derived rail.

Ghi chú thiết kế
Estimated: at 32 MHz full-speed operation, PIC24FJ256GU410-I/PT draws approximately 15 mA from a 3.3V supply. Decouple VDD with a 10 uF bulk + 0.1 uF ceramic in parallel, placed within 5 mm of each VDD pin (the part has 4 VDD pins). VUSB (pin 89) requires its own 0.1 uF + 4.7 uF bypass pair per USB spec. Do not back-power VUSB from external sources - the internal 3.3V LDO is always on and conflicts with external 3.3V drive.
Route USB D+/D- as a 90 ohm differential pair on the top layer with continuous ground reference beneath; avoid via stubs and keep total length under 50 mm for full-speed USB. Place the optional 27-ohm series termination close to the IC. Place the 12.000 MHz primary crystal (or resonator) within 5 mm of OSCI/OSCO pins with guard traces and a clean ground pour. Keep LCD segment traces away from USB to reduce cross-talk on segment lines.
Do not omit the dual-partition Golden Image bootloader if you intend to use OTA updates - without it, a failed firmware update bricks the device. Configure MCLR as a reset input with a proper 10 kohm pull-up to VDD; floating MCLR leads to spurious resets. The VUSB pin must NOT be connected to an external 3.3V rail or the internal LDO will be damaged. Finally, the LCD charge pump capacitors on S010/S011/S012/S013 must match the segment pinout section of the datasheet or the display contrast will be wrong.
For USB-OTG host mode, the VBUS pin requires a power-switch IC (such as MIC2026) controlled by a GPIO; do not drive VBUS directly from the MCU - the GPIO is 5V-tolerant but cannot source enough current for USB host mode. When using the 12-bit ADC for sensor measurements in noisy USB environments, average multiple samples and place a small RC filter at the ADC input. Keep switching regulator switching nodes away from the ADC traces to avoid coupling noise into measurements.
