W9812G2IH-6 – SDR SDRAM – Winbond
The Winbond W9812G2IH-6 is a 128Mbit SDR SDRAM organized as 4M x 32 bits (4 banks), rated for 166MHz / CAS Latency 3 operation in an 86-pin TSOP-II package at a 3.3V supply. This obsolete, hard-to-find memory is available now for RFQ at Pacific Component Xchange.
The Winbond W9812G2IH-6 is a high-speed 128Mbit single-data-rate synchronous DRAM (SDR SDRAM) organized as 1,048,576 words x 4 banks x 32 bits (4M x 32). Built on Winbond’s mature SDRAM process and housed in an 86-pin TSOP-II package, the device operates from a 3.3V supply and is rated to the 166MHz / CAS Latency 3 (-6) speed specification. It is a 32-bit-wide SDRAM commonly used as a drop-in memory in legacy 32-bit designs.
As part of the long-running W9812 128Mb SDRAM family, the W9812G2IH-6 remains a frequently specified replacement part for legacy industrial, networking, and embedded systems that were designed around a 32-bit-wide SDR SDRAM interface. This part is now obsolete with little to no authorized-channel availability, which is where Pacific Component Xchange can help.
