This implementation of multiple functions in one SMT package is ideal for applications ranging from cellular phones to PDAs and other small electronic devices.

When a value is written to the second counter, the internal counter is also reset to zero in less than one second. Alarm W function” and for the Alarm D function, see “8.

Select between hr and hr clock mode. Consequently, SCL and SDA are both held at high level when the bus is released when communication is not being performed. Power-on reset detection This function detects when a power-on reset occurs. This pin’s signal is used for input and output of address, data, and ACK bits, synchronized 2 with the serial clock used for I C communications.

GND pattern recommended area 3? Precision gap per month: Default Power-on reset was detected result is that bit value is held until cleared to zero? Eppson this function operates, the PON bit value becomes “1”. There is no effect when the WALE bit becomes “0”. Since the internal oscillation circuit is driven at a constant voltage, In this area, at a parts side of board, do not pattern layout surely. S 0 Slave address 7 bits Write 2 A 1 1 0 0 1 0 0 Address setting rx025 h?


Note with caution that writing non-existent date data may interfere with normal operation of the calendar epaon. Note with caution that both write and read operations are invalid for communications that occur during or after this auto clearing operation.

When the read operation is invalid, all data that is read has a value of “1”. Auto calculation of leap years until ? RX – Other I C bus device Any device that controls the transmission and reception of data is defined as a master device and any device that is controlled by a master device is defined as a slave device.

If a “1” has already been written to this bit, it is cleared to zero when stopping of internal oscillation is detected. Clock Precision Adjustment Function Use registers to specify either of two voltage threshold values: Also, be sure to avoid entering incorrect date and time data, as clock operations are not guaranteed when the time data is incorrect.

Frequency and temperature characteristics can be approximated using the following equations. The default value is the value that is read or is set internally after the PON bit has been set to “1,” such as after powering up from 0 V or recovering from a supply voltage drop. This RTC module also provides a special read method that uses fewer read steps.



Overview of Functions 1 Clock functions This function is used to set and read out month, date, day, hour, minute, and second. The starting and stopping of communications is controlled at the rising edge or falling edge of SDA while SCL rx8052 at high level. The relation between the clock pulse and the count operation is shown below. While the oscillation stop detection function is useful for determining when clock data has become invalid, the supply voltage monitoring function is useful for determining whether or not the clock data is able to become invalid.

The data format is BCD format except during hour mode. Coefficient of secondary temperature -6 2? Contact the battery manufacturer for details regarding applied resistance values. Power supply voltage monitoring function with selectable detection threshold? Clock Precision Adjustment Function The clock precision can be set ahead epsno behind. Indicates next byte will be read. Also, check again if the mounting conditions are later changed.

Their value when read will be “0”. You are also requested that you would not make the products available to any third party who may use the products for such prohibited purposes.
