Signal description
CE
Input
This is a chip enabled input pin with the builit-in pull-down resistance.
When the CE pin is at the "H" level, access to this RTC becomes possible.
When the CE pin is at the "L" level, the DATA pin is at the high impedance level and
the CLK and DATA pins cannot accept input.
CLK
Input
This is a shift clock input pin for serial data transmission. In the write mode, it takes in
data from the DATA pin using the CLK signal rise edge. In the read mode, it outputs
data from the DATA pin using the fall edge.
DATA
Bi-directional
This is a data input/output pin for serial data transmission. After the input rise of CE, by
using the first 8-bit write data to set the write or read mode, this pin can be set as either
input pin or output pin.
FOUT
Output
This pin outputs the clock signal of frequency. (32.768 kHz CMOS output).
Depending
on the FOE input pin, output from the FOUT pin can be prohibited.
FOE
Input
This is the input pin for the FOUT output control.
When the FOE pin is at the "H" level,
the FOUT pin goes into the output state; when it is at the "L" level, the FOUT pin is at
the high impedance level.
VTEMP
Output
This is the voltage output pin for the temperature sensor (analog).
/ SOFF
Input
This is the input pin for the temperature sensor control. When the /SOFF pin is at the
"H" level and the SON bit is 1,
the temperature sensor circuitry starts and outputs a
voltage according to the temperature of the VTEMP pin. When the /SOFF pin is at the
"L" level, the temperature sensor circuitry stops and the VTEMP pin is at the high
impedance level.
/ AIRQ
Output
This is an open drain output pin for alarm and additional counter interrupt.
/ TIRQ
Output
This is an open drain output pin for Timer interrupt.
VDD
This pin connects to the plus side of the power.
GND
This pin connects to the minus side (ground) of the power.
N.C.
This pin is not connected internally.
But , In RTC-4701NB( SON-22pin ), all pins from 14 pin to 22 pin are connected with
inside frame mutually.
Use OPEN, or GND or VDD to connect.
* Be sure to connect a filter capacity of at least 0.1
F close to VDD GND.
