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 2.7V to

3.6V 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 and TSSOP.

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.
