168 Pin DIMM JEDEC
The W3DG7216V is a 16Mx72 synchronous DRAM
module which consists of nine 16Mx8 SDRAM components
in TSOP II package, two 18 bit Drive ICs for input control
signal and one 2Kb EEPROM in an 8 pin TSSOP package
for Serial Presence Detect which are mounted on a 168
pin DIMM multilayer FR4 Substrate.
* This product is subject to change without notice.
DESCRIPTION
FEATURES
* These pins are not used in this module.
** These pins should be NC in the system which does
not support SPD.

ABSOLUTE MAXIMUM RATINGS
Note:
Permanent device damage may occur if "ABSOLUTE MAXIMUM RATINGS" are exceeded.
Functional operation should be restricted to recommended operating condition.
Exposure to higher than recommended voltage for extended periods of time could affect device reliability.
