Manufacturer:Siemens Description:When VCC is within nominal limits (VCC > 4.5 volts) the DS1642 can be accessed as described above by read or write cycles. However, when VCC is below the power-fail point VPF (point at which write protection occurs) the internal clock registers and RAM is blocked from access. This is accomplished internally by inhibiting access via the CE signal. When VCC falls below the level of the internal battery supply, power input is switched from the VCC pin to the internal battery and clock activity, RAM, and clock data are maintained from the battery until VCC is returned to nominal level. |
