DESCRIPTION
The W3DG72128V is a 128Mx72 synchronous DRAM
module which consists of nine 128Mx8 stacks of SDRAM
components in TSOP II package, and one 2Kb EEPROM
in an 8 pin TSSOP package for Serial Presence Detect
which are mounted on a 144 pin SO-DIMM multilayer
FR4 Substrate. This module is structured as 2 Ranks of
64Mx72 SDRAM.
* This product is under development, is not qualifi ed or characterized and is subject to
change without notice..
PIN CONFIGURATIONS (FRONT SIDE/BACK SIDE)
PIN NAMES
* These pins are not used in this module.
** These pins should be NC in the system which
does not support SPD.
