Very Low Power 8-Bit 32 kHz RTC Module with Digital Trimming and High Level Integration
Description The V3022 is a low power CMOS real time clock with a built in crystal. Standby current is typically 1.2 µA and the access time is 50 ns. The interface is 8 bits with multiplexed address and data bus. 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...
