Additional preview pages of the WED3EG7232S-JD3 datasheet.

The WED3EG7232S is a 32Mx72 Double Data Rate SDRAM memory module based on 256Mb DDR SDRAM components.

The module consists of nine 32Mx8 DDR SDRAMs in 66 pin TSOP packages mounted on a 184 pin FR4 substrate.

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

Double-data-rate architecture DDR200, DDR266, DDR333 amd DDR400.
JEDEC design speciﬁcations Bi-directional data strobes (DQS) Differential clock inputs (CK & CK#) Programmable Read Latency 2, 2.5 (clock) Programmable Burst Length (2, 4, 8) Programmable Burst type (sequential & interleave) Edge aligned data output, center aligned data input. Auto and self refresh Serial presence detect Power supply:.
VCC = VCCQ = +2.5V ± 0.2V (100, 133 and 166MHz).
