NM34C02LZEM8中文资料仙童半导体数据手册PDF规格书

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).
