DESCRIPTION
The X24C08 is a CMOS 8,192 bit serial E2PROM,
internally organized 1024 x 8. The X24C08 features a
serial interface and software protocol allowing operation
on a simple two wire bus.
The X24C08 is fabricated with Xicor’s advanced CMOS
Textured Poly Floating Gate Technology.
The X24C08 utilizes Xicor’s proprietary Direct Write™
cell providing a minimum endurance of 100,000 cycles
and a minimum data retention of 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.
Address (A0, A1)
A0 and A1 are unused by the X24C08; however, they
must be tied to VSS to insure proper device operation.
Address (A2)
The A2 input is used to set the appropriate bit of the
seven bit slave address. This input can be used static or
actively driven. If used statically, it must be tied to VSS or
VCC as appropriate. If actively driven, it must be driven
to VSS or to VCC.
