The recommended operating voltage range for the BF1105/215 is 1.8V to 3.6V, with a typical voltage of 2.5V.
To configure the BF1105/215 for optimal power consumption, use the lowest possible voltage, disable unnecessary peripherals, and use the power-down mode when not in use. Additionally, use the dynamic voltage and frequency scaling (DVFS) feature to adjust the voltage and frequency based on the system's requirements.
The maximum clock frequency supported by the BF1105/215 is 240 MHz, but it can be overclocked up to 300 MHz with careful consideration of power consumption and thermal management.
To implement secure boot on the BF1105/215, use the built-in ROM bootloader and configure it to authenticate the firmware using digital signatures or encryption. Additionally, use the secure boot key storage feature to store the boot keys securely.
The BF1105/215 can support up to 64 MB of external RAM and up to 128 MB of external flash memory, depending on the specific configuration and memory technology used.
