external components are a 32.768kHz crystal and a backup battery.
The bq4285E/L integrates a battery-backup controller to make a standard CMOS SRAM nonvolatile during power-fail
conditions. During power-fail, the bq4285E/L automatically write-protects the external SRAM and provides a VCC output
sourced from the clock backup battery.
