The maximum clock frequency that can be achieved with the internal oscillator is 72 MHz. However, this frequency is only achievable under certain conditions, such as using the HSI (High-Speed Internal) oscillator and configuring the PLL (Phase-Locked Loop) correctly.
To achieve the highest accuracy with the ADC, you should use the internal voltage reference (VREFINT), enable the ADC calibration, and use the correct sampling time and resolution. Additionally, you should ensure that the input signal is within the recommended range and that the ADC is not affected by noise or interference.
The maximum amount of current that can be sourced or sunk by the GPIO pins is 20 mA. However, this value can be limited by the power consumption of the entire device, and it's recommended to check the total current consumption to avoid overheating or damage to the device.
To implement a low-power mode, you can use the STOP or STANDBY modes, which can be configured using the PWR (Power) peripheral. You can also use the Low-Power UART (LPUART) and Low-Power Timer (LPTIM) peripherals to reduce power consumption. Additionally, you can use the clock gating feature to disable clocks to unused peripherals.
The STM32F373R8T6TR has 512 KB of flash memory, but not all of it can be used for data storage. The amount of flash memory available for data storage depends on the application code size and the amount of memory reserved for the bootloader and other system functions. Typically, around 300-400 KB of flash memory is available for data storage.
