Serial Data (SDA)
SDA is a bidirectional pin used to transfer data into
and out of the device. It is an open drain output and
may be wire-ORed with any number of open drain or
open collector outputs.

An open drain output requires the use of a pull-up
resistor. For selecting typical values, refer to the pull-

The device select inputs are used to set the device
select bits of the 8-bit slave address. This allows
multiple devices to share a common bus. These inputs
can be static or actively driven. If used statically they

Program Protect (PP)
The program protect input controls the hardware
program protect feature. When held LOW, hardware
program protection is disabled and the X24F064/
032/016 can be programmed normally. When this
input is held HIGH, and the PPEN bit in the
program protect register is set HIGH, program
protection is enabled, and nonvolatile writes are
disabled to the selected blocks as well as the
program protect register itself.
