WED3EG7232S-JD3 Datasheet 256mb - 32mx72 Ddr Sdram Unbuffered

Manufacturer: White Electronic Designs

Overview: .. WED3EG7232S-JD3 PRELIMINARY 256MB – 32Mx72 DDR SDRAM UNBUFFERED.

General Description

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

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.
