Winbond 256Mb SDRAM (16M x 16) operating at 166 MHz — a cost-effective volatile memory for embedded and consumer designs.
Product Overview
The W9825G6KH-6I from Winbond is a 256 Mbit synchronous DRAM organized as 16M x 16 bits across 4 banks. With a -6 speed grade supporting 166 MHz operation and a 3.3 V supply, it is a mainstream choice for microprocessors, FPGAs and ASICs that need external frame buffers or working memory. The industrial temperature range and standard 54-TSOP II package make it easy to design in and source.
