HT1381

The HT1380A/HT1381A 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 HT1380A/HT1381A 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 HT1380A/HT1381A has 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 HT1380A/HT1381A use 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.

HT1381 是串行计时IC 提供秒、 分钟、 小时、 天、 日期、 月份和年份信息。在每个月和闰年的天数，自动调整。的 HT1380A HT1381A 为低功耗设计的并可以运行在两种模式： 一是带 AM/PM 指示符的 12 小时模式，另一个是全天候 24 小时模式。的 HT1380A HT1381A 有几个寄存器来存储与 8 位数据格式的相应信息。32768 Hz 水晶被需要提供正确的时机。为了尽量减少的 pin 号码，的 HT1380A HT1381A 到与微处理器接口使用一个串行 I/O 传输方法。只有三条线是要求: (1) RESTB、 SCLK (2) 和 (3) I/O 的数据可以提供 1 个字节在时间或在 8 字节的突发中。
