NM34C02 2K-Bit Standard 2-Wire Bus Interface
Designed with Permanent Write-Protection for First 128 Bytes for Serial Presence Detect Application on Memory Modules Features General Description
The NM34C02 is 2048 bits of
CMOS non-volatile electrically erasable memory.
It is 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(s).
The contents of the non-volatile memory allows the CPU to determine the capacity of the module and the electrical c...
