WED3DG7216V-D2
128MB- 16Mx72 SDRAM W/ PLL, REGISTER AND SPD
FEATURES
DESCRIPTION
n Burst Mode Operation
The WED3DG7216V is a 16Mx72 synchronous DRAM module
which consists of nine 16Meg x 8 SDRAM components in TSOP11 package, two 18- bit Drive ICs for input control signal and one
2K EEPROM in an 8- pin TSSOP package for Serial Presence
Detect which are mounted on a 168 Pin DIMM multilayer FR4
Substrate.
n Auto and Self Refresh capability
n LVTTL compatible inputs and outputs
n Serial Presence Detect with EEPROM
n Fully synchronous: All signals are registered on the positive
edge of the system clock
n Programmable Burst Lengths: 1, 2, 4, 8 or Full Page
n 3.3 volt 6 0.3v Power Supply
n 168- Pin DIMM JEDEC
