1. HPM5300EVK

1.1. Overview

The HPM5300EVK provides a series of interfaces for the characteristic peripherals of the HPM5300 series microcontrollers, including an ADC input SMA interface, a first-class motor control interface, an ABZ output interface, and an RS485/422 interface. HPM5300EVK also integrates one 2x20 pin IO expansion interface, which connects most of the IOs of the HPM5300 MCU for users to freely evaluate. HPM5300EVK expands NOR Flash storage for MCU and integrates an on-board debugger.

1.5. 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 R37 with 10ohm resistors.

    

  • Revised Status

    • HPM5300EVKRevD has been revised, HPM5300EVKRevC and previous versions have this issue.
