DESCRIPTION
Standby current is typically 1.2 µA and the access time is 50 ns. Multiplexing of address and data is handled by the input line A /D. There are no busy flags in the V3022, internal time update cycles are invisible to the user's software. Time data can be read from the V3022 in 12 or 24 hour data formats. An external signal puts the V3022 in standby mode. Even in standby, the V3022 pulls the IRQ pin active low on an internal alarm interrupt. Calendar functions include leap year correction and week number calculation. Time precision can be achieved by digital trimming.APPLICATIONS
