The M29W640GB70ZF6E is a 64 megabit (Mb) electrically-erasable, programmable, read-only memory (EEPROM) from Micron Technology. This device is organized as 8,192 words by 8 bits and is accessed by a high-speed 4-byte address bus that supports both Byte and Page write operations. It is housed in a conventional 24-pin narrow SOIC (Small Outline Integrated Circuit) package. The M29W640GB70ZF6E has a fast, block-oriented erase operation, a low-power CMOS standby mode, and a two-wire and three-wire serial read/write port. It is designed and must be used with a 3.3V supply voltage, and has a max speed of 70MHz and a minimum access time of 70ns.
