Xicor SerialFlash Memories are designed and tested for

applications requiring extended endurance. Inherent

data retention is greater than 100 years.

PIN DESCRIPTIONS

Serial Clock (SCL)

The SCL input is used to clock all data into and out of

the device.

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-

up resistor selection graph at the end of this data

sheet.

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

driven, they must be driven with CMOS levels (driven

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.
