DESCRIPTION
The IS24C128 is an electrically erasable PROM
device that uses the standard 2-wire interface for
communications. The IS24C128 contains a memory
array of 128K-bits (16,384 x 8), and is further
subdivided into 256 pages of 64 bytes each for page-
write mode. This EEPROM is offered in wide operating
voltages of 1.8V to 5.5V (IS24C128-2) and 2.5V to 5.5V
(IS24C128-3) to be compatible with most application
voltages. ISSI designed the IS24C128 to be a low-cost
and low-power 2-wire EEPROM solution. The devices
are packaged in 8-pin PDIP, 8-pin SOIC, and 14-pin
TSSOP.
The IS24C128 maintains compatibility with the popular
2-wire bus protocol, so it is easy to design into
applications implementing this bus type. The simple
bus consists of the Serial Clock wire (SCL) and the
Serial Data wire (SDA). Using the bus, a Master
device such as a microcontroller is usually connected
to one or more Slave devices such as the IS24C128.
The bit stream over the SDA line includes a series of
bytes, which identifies a particular Slave device, an
instruction, an address within that Slave device, and a
series of data, if appropriate. The IS24C128 has a
Write Protect pin (WP) to allow blocking of any write
instruction transmitted over the bus.

SCL
This input clock pin is used to synchronize the data
transfer to and from the device.
SDA
The SDA is a Bi-directional pin used to transfer addresses
and data into and out of the device. The SDA pin is an open
drain output and can be wire Or'ed with other open drain
or open collector outputs. The SDA bus requires a pullup
resistor to Vcc.
A0, A1
The A0, and A1 are the device address inputs that are
hardwired or left not connected for hardware compatibility
with the 24C32/64. When pins are hardwired, as many as
four 128K devices may be addressed on a single bus
system. When the pins are not hardwired, the default A0
and A1 are zero.
WP
WP is the Write Protect pin. If the WP pin is tied to Vcc
the entire array becomes Write Protected (Read only).
When WP is tied to GND or left floating, normal read/write
operations are allowed to the device.
