W9825G6JB-6I – 256Mb SDR SDRAM – Winbond

The Winbond W9825G6JB-6I is a 256Mbit SDR SDRAM organized as 16M x 16 (4M x 4 banks x 16 bits), rated for 166MHz operation in an industrial-grade 54-ball TFBGA package. Available now for RFQ from Pacific Component Xchange.

The Winbond W9825G6JB-6I is a 256-megabit Single Data Rate Synchronous DRAM (SDR SDRAM) configured as 4,194,304 words x 4 banks x 16 bits (16M x 16). The “-6” speed grade rates the device for operation up to 166MHz (6ns rated clock parameter) at CAS latency 3, and 133MHz at CAS latency 2, while the “-I” suffix designates the industrial temperature grade, guaranteed across -40°C to +85°C. The device is supplied in a compact 54-ball TFBGA (8mm x 8mm) package and operates from a single 3.3V supply with an LVTTL interface, making it a proven, JEDEC-compliant SDRAM for embedded systems, FPGAs, and microcontroller frame buffers.
