DESCRIPTION
The X24C04 is a CMOS 4096 bit serial E2PROM,
internally organized 512 x 8. The X24C04 features a
serial interface and software protocol allowing operation
on a simple two wire bus.
The X24C04 is fabricated with Xicor’s advanced CMOS
Textured Poly Floating Gate Technology.
The X24C04 utilizes Xicor’s proprietary DirectWrite™
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)
A0 is unused by the X24C04, however, it must be tied to
VSS to insure proper device operation.
Address (A1, A2)
The Address inputs are used to set the appropriate bits
of the seven bit slave address. These inputs can be used
static or actively driven. If used statically they must be
tied to VSS or VCC as appropriate. If driven they must be
driven to VSS or to VCC.
