This pin is used by the manufacturer for testing. Any product described in this material may contain technology or the subject relating to strategic products under the epsoon of the Foreign Exchange and Foreign Trade Law of Japan and may require an export licence from the Ministry of International Trade and industry or other approval from another government agency. The reflow conditions within our reflow profile is recommended. There is no limit to the number of bytes transferred during actual communications.

Be sure to select between hour and hour clock operation before writing the time data. Supply voltage has dropped but oscillation continues. Built-in high-precision clock precision control logic? This pin is not connected to the internal IC.

Supply voltage has dropped and oscillation has stopped. The layout shown above is a simplified drawing of the seal and label.

Do not connect externally. The steps for standard reading of the I C bus are shown below. Their value when read is always “0”. Description of Pins 3.


This pin has the same voltage level as GND. RX – NB 1. This does not include instances where the master device intentionally does not generate an ACK signal. This minute counter counts from “00” to “01,” “02,” and up to 59 minutes, after which it starts again from 00 minutes. Epson Toyocom does not assume any liability for the occurrence of infringing any patent or copyright of a third party.

Tiny RTC I2C

Be sure to set a “0” for any bit whose value is shown above as “0”. Reference profile for our evaluation of Soldering heat resistance. The relation between the clock pulse and the count operation is shown below. For details on the Alarm W function, see “8.

When a device is used for both transmitting and receiving data, it is defined as either a transmitter or receiver depending on these conditions. Use a secondary cell or lithium cell. Supply voltage has dropped to 0 V. Consequently, SCL and SDA are both held at high level when the bus is released when communication is not being performed.

The receiving device responds to this communication only when the specified slave address it has received matches its own slave address. This RTC’s slave address is [ ? FOUT terminal is The power drop detection function supply voltage monitoring function uses registers to record when the supply voltage drops below a specified voltage threshold value.


This implementation of multiple functions in one Tx8025 package is ideal for applications ranging from cellular phones to PDAs and other small electronic devices.

Frequency deviation in any temperature? Auto calculation of leap years until ? 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.


This pin is connected to a positive power supply. The TEST bit is used by the manufacturer for testing. Default Setting prohibited do not set this bit value, even e;son it has no effect? The cylinder of the crystal oscillator can be seen in this area back and frontbut it has eppson affect on the performance of the device.

In addition, only soldering irons, measurement circuits, and other such devices which do not leak high voltage should rrx8025 used with this module, which should also be grounded when such devices are being used. Any part of this material may not be reproduced or duplicated in any form or any means without the written permission of Epson Toyocom.

There is no effect when the DALE bit becomes “0”.
