Description
The V3020 is a low power CMOS real time clock.
Data is transmitted serially as 4 address bits and 8 data bits, over one line of a standard parallel data bus.
Features
- Supply current typically 390 nA at 3V 50 ns access time with 50 pF load capacitance Fully operational from 1.2V to 5.5V No busy states or danger of a clock update while
accessing Serial communication on one line of a standard
parallel data bus or over a conventional 3 wire serial interface Interface compatible with both Intel and Motorola Seconds, minutes, hours, day of month, month, year, week day and week number in BCD format Leap year and week number correction Time set lock.
