              HT1380  HT1381 -- Serial Timekeeper Chip HT1380  HT1381

              General Description HT1380  HT1381

              The HT1380  HT1381 is a serial timekeeper IC which provides seconds, minutes, hours, day, date, month and year information. The number of days in each month and leap years are automatically adjusted. The HT1380  HT1381 IS designed for low power consumption and can operate in two modes: one is the 12-hour mode with an AM/PM indicator, the other is the 24-hour mode.

              The HT1380  HT1381has several registers to store the corresponding information with 8-bit data format. A 32768Hz crystal is required to provide the correct timing. In order to minimize the pin number, the HT1380  HT1381use a serial I/O transmission method to interface with a microprocessor. Only three wires are required: (1) RESTB, (2) SCLK and (3) I/O. Data can be delivered 1 byte at a time or in a burst of up to 8 bytes.
