Then, choose either single mode or burst mode to input the datadheet Maximum input serial clock: Download datasheet Kb Share this page. The value of the capacity depends on how accurate the crystal is. However, Holtek assumes no responsibility arising from the use of the specifications described.

For the most up-to-date information, please visit our web site at http: These are stress ratings only. When D5 is logic 1, it is PM, otherwise it? Refer to the table shown below and follow the steps to write the data to the chip.

Two datashert transmission modes: In total, 16 clock pulses are needed for a single byte mode and 72 for burst mode. REST remains at vatasheet level. The input signal of SCLK is a sequence of a falling edge followed by a rising edge and it is used to synchronize the register data whether read or write.

For data input, the data must be read after the rising edge of SCLK. The information appearing in this Data Sheet is believed to be accurate at the time of publication. The number of days in each month and leap years are automatically adjusted.

Taipei Office 5F, No. This is to determine whether a read, write, or test cycle is operated and whether a single byte or burst mode transfer is to occur. Data can be delivered 1 byte at a time or in a burst datasheft up to 8 bytes. Data can be de.

The Write Protect bit cannot be written to in the burst mode. Ht13881 is in single-byte mode ad the other is in multiple-byte mode. Refer to the suggestion table of page 7. For the most up-to-date information, please visit our web site at http: The value of the capacity depends on how accurate the crystal is. A Hz crystal is required to provide the correct timing.

These bits control the operation of the oscillator and so data can be written to the register array. The REST pin is also used to terminate either single-byte or burst mode data format. Then, choose either single mode or burst mode to input the data. We suggest that you can follow the table on the next page.

This table illustrates the correlation between Command Byte and their bits: The value of the capacity depends on how accurate the crystal is This table illustrates the correlation between Command Byte and their bits: When this bit is in high level, the hour mode is selected otherwise it?

Refer to the suggestion table of page 7. In order to obtain the correct frequency, two additional load capacities C1, Ht138 are needed.

Functional operation of this device at other conditions beyond those listed in the specification is not implied datashee prolonged exposure to extreme conditions may affect device reliability. There are eight registers used to control the month data, etc. In order to minimize. In order to obtain the correct frequency, two additional load capacities C1, C2 are needed.
