FEATURES

DESCRIPTION

• Two-Wire Serial Interface, I²C^TMcompatible

–Bi-directional data transfer protocol

The IS24L128 and IS24L256 are electrically erasable

PROM devices that use the standard 2-wire interface

for communications. The IS24L128 and IS24CL256

contain a memory array of 128K-bits (16K x 8) and

256K-bits (32 x 8), respectively. Each device is

organized into 64 byte pages for page write mode.

• Low Voltage and Standard Voltage Operation

–Vcc = 1.8V to 3.6V

• 400 KHz (1.8V) and 1 MHz (2.5V, 2.7V, 3.6V)

compatibility

• Low Power CMOS Technology

–Active Current less than 3 mA (3.6V)

–Stanby Current less than 3 µA (3.6V)

–Standby Current less than 1 µA (1.8V)

• Hardware Data Protection

–Write Protect Pin

This EEPROM operates in a voltage range of 1.8V to

3.6V for low voltage and standard voltage application

levels. ISSI designed this device family to be a

practical, low-power 2-wire EEPROM solution. The

devices are available in 8-pin PDIP, 8-pin (JEDEC)

SOIC, and 8-pin (EIAJ) SOIC packages.

The IS24L128/256 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 IS24L128/256. 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 IS24L128/256 has a

Write Protect pin (WP) to allow blocking of any write

instruction transmitted over the bus.

• Sequential Read Feature

• Filtered Inputs for Noise Suppression

• Self time write cycle with auto clear

–5 ms max @ 1.8V

• Organization:

IS24L128–16Kx8 (256 pages of 64 bytes)

IS24L256–32Kx8 (512 pages of 64 bytes)

• 64 Byte Page Write Buffer

• High Reliability

–Endurance: 1,000,000 Cycles

–Data Retention: 40 Years

• Industrial temperature range

• 8-pin PDIP, 8-pin (JEDEC) SOIC, and 8-pin

(EIAJ) SOIC packages

• Lead-free available
