WV3EG64M64ETSU-D4 - 512MB - 64Mx64 DDR SDRAM

Description

The WV3EG64M64ETSU is a 64Mx64 Double Data Rate SDRAM memory module based on 512Mb DDR SDRAM components.

The module consists of eight 64Mx8 DDR SDRAMs TSOP-II packages mounted on a 200 pin FR4 substrate.

Synchronous design allows precise cycle control with the use of system clock.

Features

  • Fast data transfer rate: PC3200 & PC2700 Clock speeds of 200MHz & 166MHz Bi-directional data strobes (DQS) Differential clock inputs (CK & CK#) Programmable Read Latency : DDR400 (3 clock), DDR333 (2.5 clock) Programmable Burst Length (2, 4 or 8) Programmable Burst type (sequential & interleave) Edge aligned data output, center aligned data input Auto and self refresh, 7.8µs refresh interval (8K (64ms refresh) Serial presence detect (SPD) with EEPROM Serial presence detect with EEPROM VCC = VCCQ.
