Coefficient of secondary temperature -6 2? Since neither SCL nor SDA includes a protective diode on the VDD side, a data interface between hosts with differing supply voltages can still be implemented by adding pull-up resistors to the circuit board.

It is possible to enter settings for several days at the same time, in which case be sure to set a “1” for each day among WW6 to WW0 in which an alarm will occur.

Be sure to set a “0” for any bit whose value is shown above as “0”. Instead of using a chip select pin, slave addresses are allocated to each device. Slave address The I C bus device does not include a chip select pin such as is found in ordinary logic devices.

The precision of this If a “1” has already been written to this bit, it is cleared to zero when stopping of internal oscillation is detected. Detection of a voltage drop changes the VDET bit value to “1”. In addition to providing a function for generating six types of interrupts, epsn dual alarm function, an oscillation stop detection function used to determine presence of valid internal data at power-on xr8025, and a power supply voltage monitoring function, this module includes a digital clock precision adjustment function that can be used to set various levels of precision.


Default Power-on reset was detected result is that bit value is held until cleared to zero? S tx8025 Slave address 7 bits Write 2 A 1 1 0 epxon 1 0 0 Address setting 0 h? The updating of dates by the date counter varies according to the month setting.

Oscillation stop detection function used to determine presence of internal data? When not using this function, be sure to set “0” for bits F6 to Xr8025.

Next, set the day, hour, minute, and the WAFG bit. The following is a timing chart when a one-second interrupt cycle has been set. Default Setting prohibited do not set this bit value, even though it has epsoon effect? The TEST bit is used by the manufacturer for testing. Voltage sampling is performed once per second in consideration of the module’s low current consumption. Address and transfer mode settings?

Clock Precision Adjustment Function”. The steps for standard reading of the I C bus are shown below.

For example, when the “seconds” register value is epxon ” it indicates 59 seconds. When these functions are utilized in combination with the power-on reset detection function, they are useful for determining whether clock data is valid or invalid when checking for power-on from 0 V or for back-up.


The following are status spson based on various combinations of detection results. Do not connect externally. Supply voltage has dropped to 0 V. Auto calculation of leap years until ? Adjustment resolution Internal timing of adjustment Once every 20 seconds at “00”, “20” and “40” seconds bit 4 F4 1 1 1? Due to the epsoon going strategy of gradual unification of part numbers, please review product code and marking as they will change during the course of the coming months.

To determine overall clock accuracy, add the frequency precision and voltage characteristics. Select among five Periodic frequency settings: This function can eepson used to implement a higher-precision clock function, such as by: This pin is not connected to the internal IC. Suite Atlanta,GA Phone: This Epsom module also provides a special read method that uses fewer read steps.

When a power-on reset is detected, the PON bit value becomes “1”. The threshold voltage value for detection can be set via the VDSL bit as 2. Default Write 0 1 0 Read 1? The material is subject to change without notice.
