DESCRIPTIOn
The IS24C128B is an electrically erasable PROM
device that uses the standard 2-wire interface for
communications. The IS24C128B is 128K-bit (16Kx8).
These EEPROM are offered in a wide operating voltage
range of 1.8V to 5.5V to be compatible with most
application voltages. ISSI designed the IS24C128B to
be an efficient 2-wire EEPROM solution. The devices
are offered in lead free, RoHS, halogen free or Green.
The available package types are 8-pin SOIC (JEDEC)
and TSSOP.
The IS24C128B 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 IS24C128B. 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 IS24C128B has a Write Protect
pin (WP) to allow blocking of any write instruction
transmitted over the bus.
