Serial Timekeeper ChipThe 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 Electric Contact & Materials two modes: oElectronic Instrument ne 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 burIntegrated Circuit st of up to 8 bytes.Operating voltage: 2.0V~5.5V
Maximum input serial clock:
500kHz at VDD=2V, 2MHz at VDD=5V
Operating current:
less than 0.5uA at 2V
less than 0.7uA at 3V
less than 1.0uA at 5V
TTL compatible
- VIH: 2.0V ~ VDD+0.3V at VDD=5V
- VIL: 0.3V ~ +0.8V at VDD=5V
Two data transmission modes: Spraying Machinery & Spreading Equipment single-byte or burst mode
Serial I/O transmission
All registers store BCD format
