NM34W02 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 Compliant) General Description
The NM34W02 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 communications protocol uses CLOCK (SCL) and DATA I/O (SDA) lines to synchronously clock data between the master (for example a microprocessor) and the slave EEPROM device(...
