AiP8563

AiP8563 is a low-power CMOS real-time clock/calendar chip, which provides a programmable clock output and an interrupt output. The address and data are transmitted serially through I2C bus interface. The maximum bus speed is 400Kbits/s, and the embedded word address register will automatically increment after reading and writing data. It is widely used in mobile phones, portable instruments, fax machines and battery powered products.

AiP1302 is a trickle charge clock chip circuit, which includes clock/calendar register and 31-byte data temporary register. The real-time clock/calendar provides information including seconds, minutes, hours, dates, months and years. Leap year can be adjusted by itself. You can choose 12-hour system and 24-hour system, and you can set AM and PM. Data transmission is controlled through three wires: CE, I/O and SCLK.  

AiP1307 is a low-power real-time clock (RTC). Full binary-coded decimal (BCD) clock/calendar plus 56 bytes of SRAM. Address and data are transferred serially through an 2-line bidirectional bus. The clock/calendar provides the information of seconds, minutes, hours, day, date, month, and year . The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator. AiP1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Timekeeping operation continues while the part operates from the backup supply.
