PRELIMINARY INFORMATION  
June 2000  
FM34W02  
2K-Bit Standard 2-Wire Bus Interface Serial EEPROM  
with Full Array Write Protect  
Designed with Permanent Write-Protection for First 128 Bytes for Serial Presence  
Detect Application on Memory Modules (PC100/PC133 Compliant)  
General Description  
Features  
The FM34W02 is 2048 bits of CMOS non-volatile electrically  
erasable memory. This device is specifically designed to support  
Serial Presence Detect circuitry in memory modules. This com-  
munications protocol uses CLOCK (SCL) and DATA I/O (SDA)  
lines to synchronously clock data between the master (for ex-  
ample a microprocessor) and the slave EEPROM device(s).  
I PC100/PC133 Compliant  
I Extended Operating Voltage: 2.7V-5.5V  
I Software Write-Protection for first 128 bytes  
I Hardware Write-Protection for entire memory array  
I 200 µA active current typical  
The contents of the non-volatile memory allows the CPU to  
determine the capacity of the module and the electrical character-  
istics of the memory devices it contains. This will enable "plug and  
play" capability as the module is read and PC main memory  
resources utilized through the memory controller.  
– 1.0 µA standby current typical (L)  
– 0.1 µA standby current typical (LZ)  
I IIC compatible interface  
– Provides bidirectional data transfer protocol  
I Sixteen byte page write mode  
– Minimizes total write time per byte  
The first 128 bytes of the memory of the FM34W02 can be  
permanentlyWriteProtectedbywritingtothe"WRITEPROTECT"  
Register. Write Protect implementation details are described  
underthesectiontitledAddressingtheWPRegister. Inaddition,  
like the NM24Wxx product family, the entire memory array can be  
write-protected through "WP" pin.  
I Self timed write cycle  
- Typical write cycle time of 6ms  
I Endurance: 1,000,000 data changes  
I Data retention greater than 40 years  
TheFM34W02isavailableinaJEDECstandardTSSOPpackage  
for low profile memory modules for systems requiring efficient  
spaceutilizationsuchasinanotebookcomputer. Twooptionsare  
available: L - Low Voltage and LZ - Low Power, allowing the part  
to be used in systems where battery life is of primary importance.  
I Packages available: 8-pin TSSOP and 8-pin SO  
I Temperature Ranges: Commercial and Extended
