TMS320F243PGE datasheet by Texas Instruments

TMS320F243PGE Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the internal oscillator?
  The maximum clock frequency that can be used with the internal oscillator is 10 MHz. However, it's recommended to use a crystal oscillator or an external clock source for more accurate and stable clocking.
• How do I configure the flash memory to store both code and data?
  The flash memory can be configured to store both code and data by using the Flash Memory Control Registers (FMCR) to set the flash memory partitioning. The FMCR registers allow you to define the boundaries between the code and data sections.
• What is the maximum 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's recommended to limit the current to 2 mA to ensure reliable operation and to prevent overheating.
• How do I implement a watchdog timer on the TMS320F243PGE?
  The TMS320F243PGE has a built-in watchdog timer that can be enabled and configured using the Watchdog Timer Control Registers (WTCSR). The watchdog timer can be used to reset the device in case of a software fault or hang.
• What is the minimum voltage required for the analog-to-digital converter (ADC) to operate correctly?
  The minimum voltage required for the ADC to operate correctly is 2.7 V. The ADC requires a minimum voltage of 2.7 V to ensure accurate conversions.
