Data contained in the clock register is in binary coded decimal format. When D5 is logic 1, it is PM, otherwise it?
Holtek reserves the right to alter its products without prior notification. When this bit is written to logic 0, the clock will start.

Elcodis is a trademark of Elcodis Company Ltd. A Hz crystal is required to. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability. A Hz crystal is required to provide the correct timing. The value of the capacity depends on how accurate the crystal is.
HT/HT – Product Details – Holtek
Taipei Office 5F, No. The value of the capacity depends on how accurate the crystal is Data inputs are entered starting with bit 0.
Data can be de- livered 1 byte at a time burst bytes Holtek reserves the right to alter its products without prior notification.
Then, choose either single mode or burst mode to input the data. The number of days in each month and leap years are automatically adjusted. This table illustrates the correlation between Command Byte and their bits: The read or write operating flowcharts are shown on the next page. For the most up-to-date information, please visit our web darasheet at http: Only three wires are required: One is in single-byte mode ad the other is in multiple-byte mode.
The REST pin is also used to terminate either single-byte or burst mode data format. These are stress ratings only. Both input and output data starts with bit 0. Two data transmission modes: Maximum input serial clock: The information appearing in this Data Sheet is believed to be accurate at the time of publication.
Two modes are available for transferring the data between the microprocessor and the Command byte For daatsheet data transfer, a Command Byte is initiated to specify which register is accessed. Only three wires are required: All other trademarks are the property of their respective owners.
The input signal of SCLK is a sequence of datxsheet falling edge followed by a rising edge and it is used to synchronize the register data whether read or write.
This table illustrates the correlation between Command Byte and their bits: The clock halt bit must be set to logic 1 oscillator datasheeet. Data can be de. Refer to the table shown below and follow the steps to write the data to the chip. Data can be written into the designated register only if the Write Protect signal WP is set to logic 0.
Download datasheet Kb Share this page. Copy your embed code and put on your site: Only three wires are required:. This is to determine whether a read, write, or test cycle is operated and whether a single byte bt1381 burst mode transfer is to occur.
We suggest datasheeet you can follow the table on the next page. Data outputs are read starting with bit 0. However, Holtek assumes no responsibility arising from the use of the specifications described. Pad Description Pad No. In order to obtain the correct frequency, two additional load capacities C1, C2 are needed.
A Hz crystal is required to provide the correct timing.
The test dattasheet is used by Holtek only for testing purposes. The value of the capacity depends on how accurate the crystal is. These bits control the operation of the oscillator and so data can be written to the register array. Data can be delivered 1 byte at a time or in a burst of up to 8 bytes.
There are eight registers used to control the month data, etc. In order to minimize.
