• FDT bit: Supply voltage detection bit

• This bit is set to “1” when voltage of 1.7 ±0.3 V or less is detected between VDD and GND.

• The FDT bit is cleared if all of the digits up to the year digits are read.

• Although this bit can be both read and written, normally set this bit to “0”.

Output data does not change

Year

1) When the WR pin is low and the CE pin is high, the RTC enters data output mode.

2) At the first rising edge of the CLK signal, the clock and calendar data are loaded into the shift

register and the LSB of the seconds digits is output from the DATA pin.

3) The remaining seconds, minutes, hour, day of the week, day, month, and year data is shifted out,

in sequence and in synchronization with the rising edge of the CLK signal, so that the data is

output from the DATA pin.

The output data is valid until the rising edge of the 52nd clock pulse; even if more than 52 clock

pulses are input, the output data does not change.

4) If data is required in less than 52 clock pulses, that part of the data can be gotten by setting the

CE pin low after the necessary number of clock pulses have been output.

Example: If only the data from “seconds” to “day of the week” is needed:

After 28 clock pulses, set the CE pin low in order to get the data from “seconds” to “day of

the week.”

5) When performing successive data read operations, a wait (tRCV) is necessary after the CE pin

is set low.

6) Note that if an update operation (a one-second carry) occurs during a data read operation,

the data that is read will have an error of -1 second.

7) Complete data read operations within tCE (Max.) = 0.9 seconds, as described earlier.

1) When the WR pin is high and the CE pin is high, the RTC enters data input mode.

2) In this mode, data is input, in succession and in synchronization with the rising edge of the CLK

signal, to the shift register from the DATA pin, starting from the LSB of the seconds digits.

3) The sub-seconds counter is reset between the falling edge of the first clock pulse and the rising

edge of the second clock pulse. In addition, carries to the seconds counter are prohibited at the

falling edge of the first clock pulse.

4) After the last data is input to the shift register at the rising edge of the 52nd clock pulse, the

contents of the shift register are transferred to the timer counter.

5) Note that during a data write operation, 52 bits of data must be input.

• Correct write-access isn't completed when CE terminal turned into low on a state of less

than 52 bits.

• If more than 52 bits of data are input, the 53rd and subsequent bits are ignored.

(The first 52 bits of data are valid.)

6) Once the CE pin is set low, the prohibition on carries to the seconds counter is lifted.

Complete data write operations within tCE (Max.) = 0.9 seconds, as described earlier.

7) If a data read operation is to be performed immediately after a data write operation, a wait (tRCV)

is necessary after the CE pin is set low.

* Malfunction will result if illegal data is written. Therefore, be certain to write legal data.

During a data write operation, because a reset is applied to the Devider counter (from the 128 Hz

level to the 1 Hz level) after the CE pin goes high during the time between the falling edge of the first

clock cycle and the rising edge of the second clock cycle, the length of the first 1 Hz cycle after the

data write operation is 1.0 s +0 / −7.8ms +tCES+tCLK. Subsequent cycles are output at 1.0-second intervals.

The 1-Hz signal that is output on FOUT is the internal 1-Hz signal with a 15.6-ms shift applied.

12. Application notes

12-1. Notes on handling

This module uses a C-MOS IC to realize low power consumption. Carefully note the following cautions when

handling.

(1) Static electricity

While this module has built-in circuitry designed to protect it against electrostatic discharge, the chip

could still be damaged by a large discharge of static electricity. Containers used for packing and

transport should be constructed of conductive materials. 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.

(2) Noise

If a signal with excessive external noise is applied to the power supply or input pins, the device may

malfunction or "latch up." In order to ensure stable operation, connect a filter capacitor (preferably

ceramic) of greater that 0.1F as close as possible to the power supply pins (between VDD and GNDs).

Also, avoid placing any device that generates high level of electronic noise near this module.

* Do not connect signal lines to the shaded area in the figure shown in Fig. 1 and, if possible, embed

this area in a GND land.

(3) Voltage levels of input pins

When the input pins are at the mid-level, this will cause increased current consumption and a reduced

noise margin, and can impair the functioning of the device. Therefore, try as much as possible to apply

the voltage level close to VDD or GND.

(4) Handling of unused pins

Since the input impedance of the input pins is extremely high, operating the device with these pins in

the open circuit state can lead to unstable voltage level and malfunctions due to noise. Therefore, pull-

up or pull-down resistors should be provided for all unused input pins.

12-2. Notes on packaging

(1) Soldering heat resistance.

If the temperature within the package exceeds 260, the characteristics of the crystal oscillator will be

degraded and it may be damaged. The reflow conditions within our reflow profile is recommended.

Therefore, always check the mounting temperature and time before mounting this device. Also, check

again if the mounting conditions are later changed.

* See Fig. 2 profile for our evaluation of Soldering heat resistance for reference.

(2) Mounting equipment

While this module can be used with general-purpose mounting equipment, the internal crystal oscillator

may be damaged in some circumstances, depending on the equipment and conditions. Therefore, be

sure to check this. In addition, if the mounting conditions are later changed, the same check should be

performed again.

(3) Ultrasonic cleaning

Depending on the usage conditions, there is a possibility that the crystal oscillator will be damaged by

resonance during ultrasonic cleaning. Since the conditions under which ultrasonic cleaning is carried

out (the type of cleaner, power level, time, state of the inside of the cleaning vessel, etc.) vary widely,

this device is not warranted against damage during ultrasonic cleaning.

(4) Mounting orientation

This device can be damaged if it is mounted in the wrong orientation. Always confirm the orientation of

the device before mounting.

(5) Leakage between pins

Leakage between pins may occur if the power is turned on while the device has condensation or dirt on

it. Make sure the device is dry and clean before supplying power to it.
