DESCRIPTION
The X24C16 is a CMOS 16,384 bit serial E2PROM,
internally organized 2048 X 8. The X24C16 features a
serial interface and software protocol allowing operation
on a simple two wire bus.
The X24C16 is fabricated with Xicor’s advanced CMOS
Textured Poly Floating Gate Technology.
The X24C16 utilizes Xicor’s proprietary Direct WriteTM
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, A2)
The A0, A1 and A2 inputs are unused by the X24C16,
however, they must be tied to VSS to insure proper
device operation.
