5. HPM6300EVK

5.1. Overview

HPM6300EVK provides interfaces for most of the peripherals of the HPM6300 microcontroller, including 1 SD card slot, 1 USB Type-C interface, a 100M Ethernet port, CAN FD interface, etc., and expands NOR Flash, SDRAM and other external memories, and integrates an on-board debugger.

5.2. Hardware

• HPM6360IPA MCU

• Onboard Memory

  • 16bit 256Mb SDRAM

  • 128Mb Quad SPI NOR Flash

• USB

  • USB type C (USB 2.0 OTG) connector x2

• Ethernet

  • 100Mb PHY

• Others

  • TF Slot

  • CAN FD

  • FT2232

• Expansion port

  • Motor control port

  • Raspberry PI extension port

Note

The sdram pins are multiplexed with the 15-20pin of the motor interface J26, so the motor interface and sdram can’t be used at the same time.

5.7. Board Know Issue

• USB VBUS pin resistance issue

  • Impact

    • This issue may affect the Host’s ability to enumerate USB as a device.

  • Solution

    • Replace the 1kohm resistors R135 with 10ohm resistors.

    

  • Revised Status

    • HPM6300EVKRevD has been revised, HPM6360-EVK-A3 and previous versions have this issue.

• USB ID pin pull down resistance issue

  • Impact

    • When using USB OTG, this issue may affect the role recognition of USB connected device or connected host.

  • Solution

    • Remove the pull-down resistors R127, R128 from the CC port of the USB interface.

    

  • Revised Status

    • HPM6300EVKRevD has been revised, HPM6360-EVK-A3 and previous versions have this issue.
