IS24C256  
ISSI  
262,144-bit 2-WIRE SERIAL  
CMOS EEPROM  
ADVANCEDINFORMATION  
MARCH 2003  
DESCRIPTION  
The IS24C256 is an electrically erasable PROM device  
that uses the standard 2-wire interface for  
FEATURES  
• Organization:  
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.  
– 32K-bit x 8-bit  
• 64-Byte Page Write Buffer  
• Two-Wire Serial Interface  
– Bi-directional data transfer protocol  
• Low Power CMOS Technology  
– Active Current less than 3 mA (5V)  
– Standby Current less than 6 µA (5V)  
– Standby Current less than 2 µA (2.5V)  
• Wide Voltage Operation  
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.  
– IS24C256-2: Vcc = 1.8V to 5.5V  
– IS24C256-3: Vcc = 2.5V to 5.5V  
• 1 MHz (I2CTM Protocol) Compatibility  
• Hardware Data Protection  
– Write Protect pin  
• Sequential Read Feature  
• Filtered Inputs for Noise Suppression  
• Self time Write cycle with auto clear  
– 5 ms @ 5.0V  
• HighReliability  
– Endurance: 100,000 Cycles  
– Data Retention: 40 Years  
• Commercial and Industrial temperature ranges  
• 8-pin PDIP, 8-pin SOIC, and 14-pin TSSOP
