IS24C52  
ISSI  
2k-bit 2-WIRE SERIAL CMOS EEPROM  
with Permanent Write-Protection  
ADVANCEDINFORMATION  
JANUARY2004  
FEATURES  
DESCRIPTION  
• Two-Wire Serial Interface  
The IS24C52 is an electrically erasable PROM device  
that uses the standard 2-wire interface for  
– Bidirectional data transfer protocol  
– 400 kHz (I2C TM Protocol) Compatibility  
communications. The IS24C52 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  
• Organization:  
– 256-bit x 8-bit  
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 (IS24C52-2) and 2.5V to 5.5V (IS24C52-  
3) to be compatible with most application voltages. ISSI  
designed the IS24C52 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.  
• 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 IS24C52 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 IS24C52. 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 IS24C52 has a Write Protect pin (WP)  
to allow blocking of any write instruction transmitted over  
the bus.  
– IS24C52-2: Vcc = 1.8V to 5.5V  
– IS24C52-3: 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  
• Commercial and Industrial temperature ranges  
• 8-pin SOIC, 8-pin TSSOP, and 8-pin MSOP
