Product Summary
The 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 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 HT1381 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 HT1381 use a serial I/O transmission method to interface with a microprocessor.
Parametrics
HT1381 absolute maximum ratings: (1)Supply Voltage: -0.3V to 5.5V; (2)Storage Temperature: -50 to 125℃; (3)Input Voltage: VSS-0.3V to VDD+0.3V; (4)Operating Temperature:0 to70℃.
Features
HT1381 features: (1)Operating voltage: 2.0V~5.5V; (2)Maximum input serial clock: 500kHz at VDD =2V, 2MHz at VDD=5V; (3)Operating current: less than 400mA at 2V, less than 1.2 μA at 5V.
