IS24L128  
IS24L256  
ISSI  
128K-bit/ 256K-bit  
2-WIRE SERIAL CMOS EEPROM  
ADVANCEDINFORMATION  
APRIL2006  
FEATURES  
DESCRIPTION  
• Two-Wire Serial Interface, I2CTM compatible  
–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
