HT1381 Real Time Clock IC
Product Price: Rs 22 / PieceGet Best Price
Minimum Order Quantity: 100 Piece
Product Details:
| Functionality | REAL TIME CLOCK IC |
| Package | 8SOPLF |
The HT1381-8SOPLF is a serial Timekeeper Chip IC which provides seconds/minutes/hours/day/date/month/year information. The number of days in each month and leap years are automatically adjusted. This is designed for low power consumption and can operate in two modes, one is the 12hour mode with an AM/PM indicator and the other is the 24hour mode. This 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 chip uses a serial I/O transmission method to interface with a microprocessor.
TTL compatible
Two data transmission modes - Single-byte or burst mode
Serial I/O transmission
All registers store BCD format
