It is a real time chip with small power consumption, which has 56 bytes non-volatile RAM BCD CODE. Address and data can be transmitted by two-wire series bus. It can provides the information of ‘second, minute, hour’ etc. Days of each month can be adjusted. There is an embedded power induction circuit which has the function of testing no electricity and battery switch.
