V3021 General Description

The V3021 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. The device is accessed by chip select (CS) with read and write control timing provided by either RD and WR pulse (Intel CPU) or DS with advanc.
