LM3S2D93-IQC80-A2T Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this microcontroller?
  The LM3S2D93-IQC80-A2T can operate from -40°C to 85°C (industrial temperature range) and from -40°C to 105°C (extended temperature range) with reduced performance.
• How do I configure the clock source for the microcontroller?
  The clock source can be configured using the PLL (Phase-Locked Loop) and the Clock Control Register (CCR). The PLL can be used to generate a clock frequency up to 80 MHz, and the CCR is used to select the clock source and configure the clock dividers.
• What is the maximum amount of current that can be sourced or sunk by the GPIO pins?
  The maximum current that can be sourced or sunk by the GPIO pins is 4 mA. However, it is recommended to limit the current to 2 mA to ensure reliable operation.
• How do I implement a watchdog timer in this microcontroller?
  The LM3S2D93-IQC80-A2T has a built-in watchdog timer that can be enabled and configured using the Watchdog Timer Control Register (WTCR). The watchdog timer can be used to reset the microcontroller in case of a software fault or hang.
• What is the maximum data transfer rate for the USB interface?
  The LM3S2D93-IQC80-A2T has a USB 2.0 interface that supports a maximum data transfer rate of 480 Mbps.
