W9751G6JB-25 – DDR2 SDRAM – Winbond

The Winbond W9751G6JB-25 is a 512Mb DDR2 SDRAM organized as 32M x 16, rated for DDR2-800 operation in an 84-ball WBGA package. Available now for RFQ from Pacific Component Xchange.

The Winbond W9751G6JB-25 is a 512-megabit Double Data Rate 2 (DDR2) Synchronous DRAM organized as 8,388,608 words x 4 banks x 16 bits (32M x 16). The “-25” speed grade is compliant with the JEDEC DDR2-800 specification (5-5-5 / 6-6-6). The device operates from a single 1.8 V supply (VDD and VDDQ = 1.8 V +/- 0.1 V), uses an SSTL_18 interface, and is supplied in an 84-ball WBGA package built with lead-free, RoHS-compliant materials.
