DESCRIPTION
The IS24C256 is an electrically erasable PROM device
that uses the standard 2-wire interface for
communications. The IS24C256 contains a memory
array of 256K-bits (32,768 x 8), and is further
subdivided into 512 pages of 64 bytes each for Page-
Write mode. This EEPROM is offered in wide operating
voltages of 1.8V to 5.5V (IS24C256-2) and 2.5V to 5.5V
(IS24C256-3) to be compatible with most application
voltages. ISSI designed the IS24C256 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 IS24C256 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 IS24C256. 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 IS24C256 has a Write
Protect pin (WP) to allow blocking of any write
instruction transmitted over the bus.
