Ground pin
Serial Data I/O pin
This is an I/O pin of serial data for performing bidirectional communication of mem-
ory address and writing or reading data. It is possible to connect some devices. It
is an open drain output, so a pull-up resistance is required to be connected to the
external circuit.
Serial Clock pin
This is a clock input pin for input/output timing serial data. Data is sampled on the
rising edge of the clock and output on the falling edge.
Write Protect pin
When Write Protect pin is “H” level, writing operation is disabled. When Write Pro-
tect pin is “L” level, the entire memory region can be overwritten. Reading operation
is always enabled regardless of the Write Protect pin state. The write protect pin is
internally pulled down to VSS pin, and that is recognized as “L” level (the state that
writing is enabled) when the pin is the open state.
