I2C for LPC2148 – RTC Epson RX8025

In particular, fluctuation in the supply voltage may occur as shown in the figure at right, such as when a back-up battery is used. Frequency deviation in any? Epson Toyocom does not assume any liability for the occurrence of infringing rx80025 patent or copyright of a third party.

During data transfers, data changes that occur on the SDA line are performed while the SCL line is at low level, and on the receiving side the data is captured while the SCL line is at high level.

Containers used for packing and transport should be constructed of conductive materials. The various detection Functions Also, be sure to avoid entering incorrect date and time data, as clock operations are not guaranteed when the time data is incorrect.

DC Electrical Characteristics 7. To determine overall clock accuracy, add the frequency precision and voltage characteristics. For description of the Alarm W function, rx805 supports only day, hour, and rx80025 data, see “8. Built-in high-precision clock precision control logic? There is no limit to the number of bytes transferred during actual communications.

The data format is BCD format.

Overview of Functions 1 Clock functions This function is used to set and read out month, date, day, hour, minute, fx8025 second. A zero is returned when any of these bits is read. Also, any device that transmits data is defined as a transmitter and any device that receives data is defined as a receiver. Fh Transfer mode 0 1 0 0 A? Example of voltage fluctuation that makes oscillation stop hard to detect VDD Fpson prohibited do not set this bit value, even though it has no effect Sets the oscillation stop detection function as use-enabled and sets up for next detection operation Oscillation stop was detected result is that bit value is held until a “1” is written Oscillation stop was not detected 8.

Frequency deviation in any voltage 3. For example, when the “seconds” register value is ” ” it indicates 59 seconds. The various detection Functions The detection functions include detection of power-on epsob, oscillation stops, and supply voltage drops, as well as reporting of detection results in corresponding bits of the address Fh Control 2 register.

This RTC’s slave address is [ ? Supply voltage has dropped to 0 V. Any two-digit year that is a multiple of 4 is treated as a leap epdon and calculated automatically as such until the year The updating of dates by the date counter varies according to the month setting. The precision of this Address and transfer rs8025 settings?

The information, applied circuit, program, usage etc. Use a secondary cell or lithium cell. We apologize for the inconvenience, but we will eventually have a unified part numbering system for Epson Toyocom which will be user friendly.

This material does not authorize the licensing for rx825 patent or intellectual copyrights. Voltage sampling is performed once per second in consideration of the module’s low current consumption.

These products are intended for general use in electronic equipment. SON – 22pin 3. Address D a reserved register is used for the manufacturer’s settings. Wide clock retention voltage range: At this point, all other register values are undefined, so be sure to perform a reset before using the module.

No supply voltage drop, but oscillation has stopped. Be careful to rx8205 writing a “1” to this bit when writing to other bits. When a power-on reset is dpson, the PON bit value becomes “1”. Coefficient of secondary temperature -6 2?

Supply voltage has dropped but oscillation continues. Power supply voltage monitoring function with selectable detection threshold? Alarm setting examples Examples of settings for alarm usage are shown below.

VDET Epsom Description Write 0 1 0 Read 1 Clears the VDET bit to zero, restarts epon power drop detection operation and sets up for next power drop detection operation Setting prohibited do not set this bit value, even though it has no effect Power drop was not detected Power drop was detected result is that bit value is held until cleared to zero?

Since no address is specified, data is read from address Fh. Therefore, if the clock’s value is read immediately after the output’s falling edge, the read clock value may appear to be about one second slower than the RTC module’s clock value. The starting and stopping of communications is controlled at the rising edge or falling edge of SDA while SCL is at high level.

Use registers to specify either of two voltage threshold values: In addition, only soldering irons, measurement circuits, and other such devices which do not leak high voltage should be used with this module, which should also be grounded when such devices are being used.
