LM3S8938-EQC50-A2 Frequently Asked Questions (FAQs)

  • The recommended crystal oscillator frequency for the LM3S8938 is 12 MHz, but it can operate with a frequency range of 10 MHz to 20 MHz.
  • The USB interface on the LM3S8938 can be configured using the USB Device Controller (UDC) module. The UDC module provides a USB 2.0 full-speed device interface and supports both device and host modes. The configuration is done through the USB Device Controller Register (UDC_REG) and the USB Endpoint Register (EP_REG).
  • The maximum current that can be sourced or sunk by the GPIO pins on the LM3S8938 is 4 mA. However, it is recommended to limit the current to 2 mA to ensure reliable operation.
  • The Ethernet MAC interface on the LM3S8938 is a 10/100 Mbps Ethernet MAC with an MII (Media Independent Interface) or RMII (Reduced Media Independent Interface) interface. It can be used with an external PHY (Physical Layer) device to implement a full Ethernet interface. The MAC interface is configured using the Ethernet MAC Register (EMAC_REG) and the PHY device is controlled using the PHY Register (PHY_REG).
  • The power consumption of the LM3S8938 varies depending on the operating mode. In active mode, the power consumption is around 250 mW at 100 MHz clock frequency. In sleep mode, the power consumption is around 10 mW, and in deep sleep mode, it is around 1 mW.
