V3022 General Description

The V3022 is a low power CMOS real time clock with a built-in crystal. Standby current is typically 1.2mA and the access time is 50ns. The interface is 8 bits with multiplexed address and data bus. The input line A/D handles multiplexing of address and data. There are no busy flag 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.
