SDA
Ground
Serial Data.
SDA is a bidirectional pin used to transfer data into and out of the device. It has an open
drain output and may be wire ORed with other open drain or open collector outputs. This pin requires
a pull up resistor and the input buffer is always active (not gated).
Watchdog Input.
A HIGH to LOW transition on the SDA (while SCL is toggled from HIGH to LOW
and followed by a stop condition) restarts the Watchdog timer. The absence of this transition within
the watchdog time out period results in WDO going active.
Serial Clock.
The Serial Clock controls the serial bus timing for data input and output.
Write Protect.
WP HIGH prevents writes to any location in the device (including all the registers). It
has an internal pull down resistor. (>10M
typical)
Battery Supply Voltage.
This input provides a backup supply in the event of a failure of the
primary V
CC
voltage. The V
BATT
voltage typically provides the supply voltage necessary to
maintain the contents of SRAM and also powers the internal logic to “stay awake.” If the battery is not
used, connect V
BATT
to ground.

Note:
There is hysteresis around V
BATT
± 0.03V point to avoid oscillation at or near the
switchover voltage. A capacitance of 0.1μF must be connected to V
OUT
to ensure stability.
Battery On.
This CMOS output goes HIGH when the V
OUT
switches to V
BATT
and goes LOW when
V
OUT
switches to V
CC
. It is used to drive an external PNP pass transistor when V
CC
= V
OUT
and current
requirements are greater than 50mA.
The purpose of this output is to drive an external transistor to get higher operating currents when the
V
CC
supply is fully functional. In the event of a V
CC
failure, the battery voltage is applied to the V
OUT
pin and the external transistor is turned off. In this “backup condition,” the battery only needs to supply
enough voltage and current to keep SRAM devices from losing their data–there is no communication
at this time.
