STR731FV2T6 datasheet by STMicroelectronics

STR731FV2T6 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the STR731FV2T6?
  The STR731FV2T6 can operate from -40°C to 85°C (industrial temperature range) and from -40°C to 125°C (extended temperature range) with some limitations.
• How do I configure the clock system on the STR731FV2T6?
  The clock system on the STR731FV2T6 can be configured using the Clock Control Register (CKCU) and the PLL Clock Register (PLLCK). The clock source can be selected from the internal RC oscillator, external crystal oscillator, or external clock signal.
• What is the maximum frequency of the STR731FV2T6?
  The maximum frequency of the STR731FV2T6 is 32 MHz, but it can be overclocked up to 40 MHz with some limitations.
• How do I use the ADC on the STR731FV2T6?
  The ADC on the STR731FV2T6 is a 10-bit successive approximation ADC. It can be configured using the ADC Control Register (ADC_CR) and the ADC Configuration Register (ADC_CFGR). The ADC can be triggered by a software trigger or an external trigger.
• What is the purpose of the BOR (Brown-Out Reset) on the STR731FV2T6?
  The BOR on the STR731FV2T6 is a feature that resets the microcontroller when the supply voltage falls below a certain threshold (typically 1.8V). This helps to prevent the microcontroller from operating erratically or unpredictably during power-on or power-down sequences.
