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 of up to 8 bytes.
Then, choose either single mode or burst mode to input the data. Refer to the suggestion table of page 7.
Only three wires are required: In order to obtain the correct frequency, two additional load capacities C1, C2 are needed. The applications mentioned herein are used solely for the purpose of illustration and Holtek makes no warranty or representation that such datasehet will be suitable without further modification, nor recommends the use of its products for application that may present a risk to human life due to malfunction or otherwise.
When it is set as? We suggest that you can follow the table on the next page. The value of the capacity depends on how accurate the crystal is. Refer to the table shown below and follow the steps to write the data to the chip.
HT – HT – Memory – Kynix Semiconductor
Refer to the table shown below and follow the steps to write the data to the chip. Data outputs are read starting with bit 0. These are stress ratings only. There are eight registers used to control the month data, etc.

Stresses exceeding the range specified under? This table illustrates the correlation between Command Byte and their bits: Two data transmission modes: The data bit outputs on the falling edge of the next eight SCLK cycles. Download datasheet Kb Share this page. Additional SCLK cycles are ignored. Data outputs are read starting with bit 0. Only three wires are required:. Two modes are available ht381 transferring the data between the microprocessor and the Command byte For each data transfer, a Command Byte is initiated to specify which register is accessed.
Data can be de- livered 1 byte at a time burst bytes Note that the first data bit to be transmitted on the first falling edge after the last bit of the read command byte is written.
The REST pin is also used to terminate either single-byte or burst mode data format. The value of the capacity depends on how accurate the crystal is Both input and output data starts with bit 0. The Write Protect Register should be set first before restarting the system or before writing the new data to the system, and it should set as logic 1 in the read cycle.
The value of the capacity depends on how accurate the crystal is. The REST pin must be taken low again after the transfer operation is completed. For data input, the data must datasheey read after the rising edge of SCLK. If used generally, unpredictable conditions may occur. Holtek reserves the right to alter its products without prior notification.
Data inputs are entered starting with bit 0. Data can be written into the designated register only if the Write Protect signal WP is set to logic 0. The input signal of SCLK is a sequence of a falling edge followed by a rising edge and it is used to dafasheet the register data whether read or write.

A Hz crystal is required to provide the correct timing. For the most up-to-date information, please visit our web site at http: Data contained in the clock register is in binary coded decimal format. When D5 is logic 1, it is PM, otherwise it? Copy your embed code and put on your site: Ut1381 input and output data starts with bit 0. One is in single-byte mode ad the other is in multiple-byte mode. A Hz crystal is required to.
