DESCRIPTIOn
The IS24C02D is an electrically erasable programmable
read only memory device that utilizes the standard
serial 2-wire interface for communications. This
EEPROM operates in a wide voltage range of 1.8V to
5.5V to be compatible with most application voltages.
The IS24C02D has an embedded memory array of
2,048-bits (256 x 8), and is organized in 16 pages of 16
bytes each. So page-write mode is capable of up to 16
bytes. In addition, software write-protection feature is
initiated with a unique irreversible instruction. After this
command is transmitted, the first 128 bytes of the array
become permanently read-only. This feature is designed
for specific applications such as, DIMMs. ISSI designed
the IS24C02D as a low-cost and low-power 2-wire
EEPROM solution. The device is offered in lead-free,
RoHS, halogen free or Green. The available package
types are 8-pin SOIC, TSSOP, PDIP, MSOP, and DFN.
The IS24C02D maintains compatibility with the popular
2-wire bus protocol, so it is easy to use in 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 IS24C02D. 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 IS24C02D has a Write Protect
pin (WP) to allow blocking of any write instruction
transmitted over the bus.
