IS34C02  
ISSI  
2K-bit 2-WIRE SERIAL CMOS EEPROM  
with Permanent Write-Protection  
ADVANCEDINFORMATION  
JANUARY2005  
FEATURES  
DESCRIPTION  
• Two-Wire Serial Interface, I2CTM compatible  
The IS34C02 is an electrically erasable PROM device  
that uses the standard 2-wire interface for  
– Bidirectional data transfer protocol  
communications. The IS34C02 contains a memory  
array of 2,048-bits (256K x 8), and is further subdivided  
into 16 pages of 16 bytes each for page-write mode.  
The 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 popular in  
applications like DRAM DIMMs to retain DRAM related  
data. This EEPROM is offered in wide operating voltages  
of 1.8V to 5.5V (IS34C02-2) and 2.5V to 5.5V (IS34C02-  
3) to be compatible with most application voltages. ISSI  
designed the IS34C02 as a low-cost and low-power 2-  
wire EEPROM solution. The devices are packaged in  
8-pin SOIC, and 8-pin TSSOP, and 8-pin MSOP.  
– 400 kHz (2.5V) and 1 MHz (5.0V) compatibility  
• Organization:  
– 256 x 8-bit  
• Data Protection Features  
– Write Protect Pin  
– Permanent Software Protection  
• 16-Byte Page Write Buffer  
– Partial Page-writes permitted  
• Low Power CMOS Technology  
– Active Current less than 2 mA (5V)  
– Standby Current less than 6 µA (5V)  
– Standby Current less than 2 µA (2.5V)  
• Low Voltage Operation  
The IS34C02 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 IS34C02. 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 IS34C02 has a Write Protect pin (WP)  
to allow blocking of any write instruction transmitted over  
the bus.  
– IS34C02-2: Vcc = 1.8V to 5.5V  
– IS34C02-3: Vcc = 2.5V to 5.5V  
• Random or Sequential Read Modes  
• Filtered Inputs for Noise Suppression  
• Self timed Write cycle with auto clear  
– 5 ms @ 2.5V  
• HighReliability  
– Endurance: 1,000,000 Cycles  
– Data Retention: 40 Years  
• Automotive and Industrial temperature ranges  
• 8-pin SOIC, 8-pin TSSOP, and 8-pin MSOP  
• Lead-free available
