LM3S2D93-IBZ80-A2 datasheet by Texas Instruments

LM3S2D93-IBZ80-A2 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this microcontroller?
  The LM3S2D93-IBZ80-A2 can operate from -40°C to 85°C (industrial temperature range) and from -40°C to 105°C (extended temperature range) with some limitations.
• How do I configure the clock source for the microcontroller?
  The clock source can be configured using the PLL (Phase-Locked Loop) or the internal RC oscillator. The PLL can be used to generate a clock frequency up to 80 MHz, while the internal RC oscillator can generate a clock frequency up to 12 MHz.
• What is the maximum amount of current that can be sourced or sunk by the GPIO pins?
  The GPIO pins can source up to 4 mA and sink up to 8 mA of current. However, the total current sourced or sunk by all GPIO pins should not exceed 100 mA.
• How do I implement a watchdog timer in this microcontroller?
  The LM3S2D93-IBZ80-A2 has a built-in watchdog timer that can be enabled and configured using the Watchdog Timer (WDT) module. The watchdog timer can be used to reset the microcontroller in case of a software fault or hang-up.
• What is the maximum data transfer rate for the USB interface?
  The LM3S2D93-IBZ80-A2 has a USB 2.0 interface that can transfer data at a maximum rate of 480 Mbps.
