Pin No. Pin Name I/O Description
2 SCL I Inputs I2C-BUS communications serial clock.
3 SDA I/O Inputs/Outputs address, data, and acknowledges bit is in
synchronization with I2C-BUS communications serial clock.
This terminal is an open drain on output. Connect the
proper pull-up resistor depending on the signal line
capacity.
14 FOUT O This is a C-MOS output terminal with the output controlled
by FOE.
In case of FOE = "H", FOUT outputs at 32.768kHz.
When no output , FOUT is at the "L" level.
10 FOE I This is an input terminal that controls the FOUT output
state.
When this terminal is at the "H" level, FOUT becomes the
output state. And when this terminal is at the "L" level,
FOUT stops.
7 /INT O Outputs an interrupt signal such as the Alarm, Timer, and
Time Update.
This terminal is an open drain terminal.
11 VDD - Connects to +(positive) power supply.
11 (VDD) - Same potential as VDD, but do NOT connect externally.
Note: RX-8581SA (SOP-14pin) does not have this terminal.
5 GND - Connects to ground.
4, 6, 8, 9,
12, 13
N.C. - Not connected to the internal IC.
OPEN, or connect to GND or VDD.
Note: Make sure that the 14pin~|22pin in RX-8581NB (SON-
22pin) ,which are the N.C. terminals, are mutually
connected by an inner cone.
Note:
Be sure to connect a bypass capacitor of more than 0.1 F to the nearest terminal between VDD and
GND.
