PIC24FJ64GP202-E/ML - 16-bit 64KB Flash USB MCU | Microchip
MPN: PIC24FJ64GP202-E/ML ✓ فعالPIC24FJ64GP202-E/ML نمای کلی
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and programmable I/O peripherals into one package. The PIC24 family uses a modified Harvard 16-bit architecture with a 24-bit instruction word, sitting hierarchically between 8-bit PIC MCUs and 32-bit ARM Cortex-M parts - well suited to mixed-signal embedded designs that need USB connectivity, low power, and moderate computational throughput.
Key features include 64KB ECC Flash for robust code storage, 8KB RAM, hardware crypto engine, Real-Time Clock and Calendar (RTCC), multiple capture/compare/PWM modules, 12-bit ADC, and configurable logic cells. The XLP technology delivers sleep currents in the hundreds of nanoamps while retaining RAM and full CPU state, enabling years of battery life on coin-cell powered designs.
The part's peripheral set includes Full-Speed USB 2.0 with on-the-go and host support, I2C, SPI, UART, and parallel master port (PMP), giving designers flexibility for HMI, sensor aggregation, and connectivity products. The 28-pin QFN-28 (6x6 mm, ML) package balances pin count with small footprint, supporting both development and space-constrained production layouts.
Typical applications include USB peripherals, wearable health monitors, low-power IoT sensor nodes, HMI touch panels, and industrial data loggers. The E-temp grade -40C to +125C operation makes it suitable for outdoor, automotive cabin, and industrial environments. Pair with the MCP2200 USB-to-UART bridge or PICkit 4 programmer for development.
When designing with this part, ensure USB DP/DM traces are 90 ohm differential and routed within 4 mm of each other. The VUSB pin requires a local 1uF decoupling cap. The MCP2221A provides a low-cost USB-serial bridge for host CDC designs. Do not exceed 3.6V on any digital I/O pin.

کاربردهای معمول
PIC24FJ64GP202-E/ML مناسب است برای 6 کاربردs: USB HID Peripheral (Mouse/Keyboard/Gamepad), Wearable Health Monitor, Industrial USB Data Logger, Low-Power IoT Sensor Node, HMI Touch Panel Controller, Smart Home Edge Device.
USB HID Peripheral (Mouse/Keyboard/Gamepad)
The PIC24FJ64GP202-E/ML integrates a Full-Speed USB 2.0 OTG transceiver plus 64 KB ECC Flash and 8 KB RAM, making it ideal for USB HID peripherals such as keyboards, mice, and game controllers. The Microchip USB stack supports HID boot protocol with minimal code overhead, while the XLP sleep current of hundreds of nA extends battery life for wireless dongle designs.

یادداشت‌های طراحی
Estimated: at VDD = 3.3 V, active core current is roughly 10-15 mA at 32 MHz. The integrated USB transceiver draws an additional 5-10 mA when active in device mode. Place a 1.0 uF ceramic decoupling capacitor within 3 mm of the VUSB pin to suppress USB inrush transients. The XLP sleep modes reduce quiescent current below 1 uA with full RAM retention.
Route USB DP and DM as a 90 ohm differential pair with 4 mm maximum trace spacing, no stubs, and a ground reference plane on the layer below. Keep DP/DM traces under 50 mm total length and isolate them from switching power and high-frequency digital signals. The exposed thermal pad on the QFN-28 (ML) package must be soldered to a ground plane for electrical and thermal performance.
Do not exceed 3.6 V on any digital I/O pin; the PIC24FJ family is not 5 V tolerant. Ensure MCLR is pulled high through a 10 kohm resistor unless external reset control is required. The ICD/PGD/PGC pins (RB6/RB7) must not be loaded with more than 25 pF capacitance during in-circuit programming. The 28-QFN QFN-28 (ML) package requires careful pad geometry to avoid solder wicking under the thermal pad.
