ST7FLITE19F1M6 datasheet by STMicroelectronics

ST7FLITE19F1M6 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with this microcontroller?
  The ST7FLITE19F1M6 can operate up to 16 MHz with an external clock source, and up to 8 MHz with an internal clock source.
• How much power does the microcontroller consume in low-power mode?
  The ST7FLITE19F1M6 consumes approximately 10 μA in low-power mode (STOP mode) with the oscillator stopped and all peripherals disabled.
• Can I use the internal oscillator as a clock source for the microcontroller?
  Yes, the ST7FLITE19F1M6 has an internal oscillator that can be used as a clock source, but it is not as accurate as an external crystal oscillator and may drift over temperature and voltage changes.
• What is the maximum amount of flash memory that can be programmed?
  The ST7FLITE19F1M6 has 16 KB of flash memory, and up to 14 KB can be programmed by the user (the remaining 2 KB is reserved for the bootloader).
• Can I use the microcontroller with a 5V power supply?
  No, the ST7FLITE19F1M6 is designed to operate from a 2.2V to 3.6V power supply, and using a 5V power supply may damage the device.
