2-WIRE SERIAL E2PROM FOR DIMM SERIAL PRESENCE DETECT
Rev.1.0_03_U
This IC is a 2-wire serial E2PROM for DIMM Serial Presence Detect which operates with low current consumption and the wide range operation. This IC has the capacity of 2 K-bit and the organization of 256 words 8-bit. Page write and sequential read are available. This IC has hardware write protect and software write protect. Hardware write protect inhibits write to all memory area when connecting the WP pin to VCC. Software write protect inhibits write in 50% of the lower address (address 00h to 7Fh) in all memory area by inputting command when the WP pin is left open or connected to the GND pin.
