OVERVIEW
The XL24C16 is a cost-effective, 16,384-bit serial
E2PROM. It is fabricated using EXEL’s advanced CMOS
E2PROM technology. This part operates from a single
power supply over the range of 1.8 to 5.5 volts.
Serial Data (SDA) - The SDA pin is a bidirectional pin
used to transfer data into and out of the device. Data may
change only when SCL is LOW, except START and STOP
conditions. It is an open-drain output and may be wire-
ORed with any number of open-drain or open-collector
outputs.
The XL24C16 is internally organized as 2,048 x 8. It
features the I2C™ serial interface and software protocol
allowing operation on a simple two-wire bus.
PIN DESCRIPTIONS
Serial Clock (SCL) - The SCL input is used to clock data
into and out of the device. In the WRITE mode, data must
remain stable while SCL is HIGH. In the READ mode, data
is clocked out on the falling edge of SCL.
Address Inputs (A0, A1, A2) - The A0, A1, A2 inputs are
unused by the XL24C16; however, to insure proper op-
eration they can be unconnected or tied to ground. They
must not be tied to VCC.
Write Control (WC) - The Write Control input pin is used
to disable the write circuitry to the memory. This input
must be tied HIGH, LOW, or left unconnected. When
HIGH, the write function is disabled, protecting previously
written data; when LOW or unconnected, the write func-
tion is enabled.

WRITE OPERATIONS
The XL24C16 allows two types of write operations: byte
write and page write. The byte write operation writes a
www.dastiansghleeetb4uy.tceomduring the nonvolatile write period (tWR). The
page write operation allows up to full 16-byte in the same
page to be written during tWR.
Byte WRITE
After the slave address is sent (to identify the slave device,
specify high order word address and a read or write
operation), a second byte is transmitted which contains
the low 8 bit addresses of any one of the 2,048 words in
the array.
Upon receipt of the word address, the XL24C16 responds
with an ACKnowledge. After receiving the next byte of
data, it again responds with an ACKnowledge. The master
then terminates the transfer by generating a STOP condi-
tion, at which time the XL24C16 begins the internal write
cycle.
While the internal write cycle is in progress, the XL24C16
inputs are disabled, and the device will not respond to any
requests from the master. Refer to Figure 6 for the
address, ACKnowledge and data transfer sequence.
Page WRITE
The XL24C16 is capable of a 16-byte page write opera-
tion. It is initiated in the same manner as the byte-write
operation, but instead of terminating the write cycle after
the first data word, the master can transmit up to 15 more
words of data. After the receipt of each word, the
XL24C16 will respond with an ACKnowledge.
The XL24C16 automatically increments the address for
subsequent data words. After the receipt of each word,
the four low order address bits are internally incremented
by one. The high order five bits of the address byte remain
constant. Should the master transmit more than sixteen
words, prior to generating the STOP condition, the ad-
dress counter will “roll over,” and the previously written
data will be overwritten. As with the byte-write operation,
all inputs are disabled during the internal write cycle.
Refer to Figure 6 for the address, ACKnowledge and data
transfer sequence.
