PIC24FJ256DA206-I/MR 概要

The Microchip Technology PIC24FJ256DA206-I/MR is a 16-bit PIC24F microcontroller with integrated graphics controller and USB On-The-Go (OTG) support, operating at up to 32 MHz (16 MIPS) with 256 KB Flash and 96 KB RAM in a 64-pin VQFN (9x9 mm) package. The -I suffix denotes the -40C to +85C industrial temperature range, while the /MR suffix indicates the QFN-64 (9x9) tape-and-reel packaging variant.

What is a PIC24F microcontroller? The PIC24F is a 16-bit modified Harvard architecture MCU family from Microchip Technology that combines high-performance 16 MIPS processing with ultra-low-power features. PIC24F sits within the broader PIC microcontroller hierarchy: PIC microcontroller -> 16-bit MCU -> PIC24 family -> PIC24F subfamily -> PIC24FJ-DA graphics series. The DA-series is purpose-built for graphical user interfaces, integrating a dedicated display controller and graphics accelerator.

Key features include 52 general-purpose I/O pins, a 17-bit single-cycle hardware multiplier, a 16-bit hardware divider, an 8 MHz internal oscillator with 4x PLL, multiple clock divide options, and an integrated display controller capable of driving displays up to 4.3-inch WQVGA (480x272 pixels). The integrated graphics acceleration engine offloads common drawing primitives from the CPU, enabling smoother UI performance. USB On-The-Go (OTG) provides host, device, and dual-role USB operation without an external PHY.

Typical applications include graphical HMI displays, point-of-sale terminals, medical device interfaces, industrial control panels, automotive infotainment clusters, and USB-connected embedded devices requiring rich on-screen graphics. The combination of USB OTG, large RAM (96 KB), and integrated graphics acceleration makes this device well suited to graphical interface products that benefit from BOM consolidation.

When designing with this part, ensure the 2.2V to 3.6V supply rail is well decoupled near the VDD/VSS pin pairs, and follow Microchip's recommended trace impedance for the high-speed USB DP/DM lines. The 9x9 mm QFN package requires thermal vias under the exposed pad for proper heat dissipation at full 32 MHz operation.

Choose the PIC24FJ256GB206-I/MR when USB OTG is needed but no display controller is required - it saves cost but loses graphical acceleration. Choose the PIC24FJ128GB406-I/MR for lower-power designs. All five parts share the same 64-pin QFN footprint, enabling PCB layout reuse across product tiers. For 100-pin designs requiring more I/O, migrate to PIC24FJ256DA210-I/PT (different package, not drop-in).

設計ノート

Estimated: At 32 MHz full operation with USB active and all peripherals enabled, the PIC24FJ256DA206-I/MR draws approximately 25 mA from VDD. The 64-pin VQFN (9x9 mm) has a typical theta_JA of 28 C/W (per the family datasheet thermal characteristics), so the junction-to-ambient rise is roughly 0.7 C/W x 25 mA x 3.3V = ~0.06 C. This is negligible - the device does not require a heatsink. However, the exposed pad (EP) MUST be soldered to a VSS copper pour with thermal vias for stable operation; failing to solder the EP can cause erratic behavior or thermal shutdown under sustained USB activity.

Place a 1 uF ceramic decoupling capacitor within 3 mm of each VDD/VSS pin pair, and a single 10 uF bulk capacitor near the IC. The VUSB pin (pin 45) requires its own 0.1 uF + 4.7 uF capacitor network per the USB OTG hardware design guide. For the high-speed USB DP/DM lines, maintain 90-ohm differential impedance with matched length traces (within 150 mils) and route over a continuous ground plane. Avoid stubs on the DP/DM differential pair.

Estimated: The 32 MHz crystal (or ceramic resonator) connected to OSC1/OSC2 should be placed within 5 mm of the IC, with a grounded guard ring around the traces to minimize noise injection. If the internal 8 MHz oscillator with 4x PLL is used instead (PLL mode selected via configuration bits), the OSC1/OSC2 pins can be repurposed as GPIO. When using the integrated display controller, keep the LCD data/control traces short (< 50 mm) and length-matched to within 1 cm to avoid skew on the parallel bus. The 52 GPIO are mapped via the Peripheral Pin Select (PPS) feature - assign functions carefully to avoid conflicts.

Common pitfalls: (1) Failing to configure the PPS registers before using remappable peripherals (UART, SPI, I2C outputs) - this causes silent peripheral failures. (2) Exceeding 3.6V on any pin, even momentarily during power-up - the device lacks 5V tolerance on all pins. (3) Forgetting to enable the VUSB 3.3V regulator before USB operations, leading to USB enumeration failures. (4) Programming Flash at voltages below 2.35V (the minimum VDD for self-programming). (5) Not populating the VCAP (pin 5) capacitor - the internal 1.8V regulator requires a 10 uF low-ESR capacitor for core supply stability.
