PIC24FJ64GU205T-I/PT 概要
What is a PIC24F microcontroller? A PIC24F is a 16-bit modified Harvard RISC microcontroller from Microchip's PIC24 family, sitting in the product hierarchy: microcontroller (MCU) -> embedded processor -> semiconductor device. PIC24F parts are designed for general-purpose low-power embedded applications and feature Core Independent Peripherals (CIPs) that perform tasks in hardware without CPU intervention, reducing active time and overall system power. The 'FJ' suffix denotes the XLP (eXtreme Low-Power) family and Flash program memory.
Key features include 16 MIPS performance at 32 MHz, a 12-bit 400 ksps ADC with up to 13 channels, three analog comparators, four 16-bit timers, configurable logic cells, multiple serial interfaces (I2C, SPI, UART), and a USB 2.0 Full-Speed transceiver with on-chip transceiver and internal pull-up. The device supports 1.8 V to 3.6 V operation with deep-sleep currents below 1 µA typical.
The PIC24FJ64GU205T-I/PT is well suited for USB Human Interface Devices (HID), sensor hubs, medical sensor patches, fitness wearables, and low-power IoT nodes where USB connectivity and battery life are both required. The integrated USB transceiver eliminates the need for an external PHY, simplifying PCB layout.
When designing with this device, allocate the VUSB and VBUS pins per datasheet recommendations and add 0.1 µF decoupling on each power pin. Configure PPS (Peripheral Pin Select) before enabling peripheral functions to avoid bus contention.

設計ノート
Decouple each VDD pin with 0.1 µF ceramic capacitor placed within 3 mm of the pin, plus a bulk 1 µF to 10 µF tantalum or ceramic capacitor near the device. For USB applications, add 0.1 µF + 4.7 µF on VUSB (USB transceiver supply) per Microchip reference design. The VCAP pin requires a low-ESR 1 µF to 10 µF ceramic capacitor for the internal core voltage regulator. Improper decoupling causes erratic USB enumeration and ADC measurement noise.
Route the USB D+ and D- traces as a 90-ohm differential pair with trace lengths matched within 150 mils. Keep the pair as short as possible and isolated from high-frequency digital signals to maintain USB signal integrity. Place the VBUS sensing resistor divider near pin 15 with 0.1 µF bypass. For crystal oscillator (OSC1/OSC2), use short traces and surround the crystal with a ground pour to minimize EMI and ensure stable 32 MHz operation. Reference the Microchip PIC24FJ64GU205 Curiosity Nano board layout for an optimal reference.
Do not omit the MCLR pull-up resistor (typically 10 kΩ to VDD) - leaving MCLR floating causes unpredictable resets, especially in noisy environments. When using the integrated USB, ensure VUSB is connected to VDD through a ferrite bead or filter, and add the recommended bulk capacitance; otherwise the USB PHY may fail USB compliance tests. PPS (Peripheral Pin Select) must be configured before enabling peripheral functions to avoid bus contention and short circuits on shared pins.
For ADC accuracy, add a 100 nF + 10 µF RC filter on each analog power input (AVDD) and route analog ground (AVSS) as a separate net back to a star ground point. The 12-bit ADC achieves 400 ksps only when the source impedance is below 1 kΩ; add an op-amp buffer for higher-impedance sensors. Avoid switching digital signals near the analog inputs during ADC conversions to prevent digital crosstalk. Reference Microchip application note AN2695 for detailed ADC layout guidance on PIC24F parts.
