W3DG72256V-D2 - SDRAM UNBUFFERED

Description

The W3DG72256V is a 256Mx72 synchronous DRAM module which consists of eighteen 256Mx4 stack 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 Su

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 168 Pin DIMM JEDEC.
  • PCB - D2: 37.34mm (1.47”).
