DESCRIPTION
The W3DG648V is a 2x4Mx64 synchronous DRAM module which consists of eight 4Mx16 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 8Mx64 SDRAM.

FEATURES
■ Burst Mode Operation
■ Auto and Self Refresh capability
■ LVTTL compatible inputs and outputs
■ Serial Presence Detect with EEPROM
■ Fully synchronous: All signals are registered on the positive edge of the system clock
■ Programmable Burst Lengths: 1, 2, 4, 8 or Full Page
■ 3.3V ± 0.3V Power Supply
■ Dual Rank
■ 144 pin SO-DIMM JEDEC
    • D1: 27.94mm (1.10")
