ST7FLITE49K2T6 datasheet by STMicroelectronics

ST7FLITE49K2T6 Frequently Asked Questions (FAQs)

• What is the recommended oscillator crystal frequency for this microcontroller?
  The recommended oscillator crystal frequency for ST7FLITE49K2T6 is 16 MHz, as specified in the STMicroelectronics application note AN1018.
• How do I configure the watchdog timer (WDT) on this device?
  The watchdog timer (WDT) on ST7FLITE49K2T6 can be configured using the WDTCSR register. The WDT can be enabled or disabled, and the timeout period can be set to one of several predefined values using the WDTCSR bits.
• What is the maximum current that can be sourced or sunk by the I/O pins?
  The maximum current that can be sourced or sunk by the I/O pins of ST7FLITE49K2T6 is 20 mA, as specified in the datasheet. However, it's recommended to limit the current to 10 mA or less to ensure reliable operation.
• How do I use the internal RC oscillator as a clock source?
  The internal RC oscillator can be used as a clock source by setting the CKSEL bits in the CLK register to '00'. The internal RC oscillator frequency can be trimmed using the OSCTCAL register.
• What is the minimum and maximum operating voltage for this device?
  The minimum operating voltage for ST7FLITE49K2T6 is 3.5 V, and the maximum operating voltage is 5.5 V, as specified in the datasheet.
