The W9816G6JB-6I is an SDRAM (Synchronous Dynamic Random Access Memory) chip manufactured by Winbond, positioned under the category and sub-category of DRAM and SDRAM PC166, respectively. This IC features a configuration of SD 1Mx16-6, indicating it has a storage capacity formulated as 1 million words by 16 bits, operating with a model specification of ‘-6’, commonly referring to its speed or latency specification. The 'I' in its name often hints at an industrial temperature range variation, making it a preferable choice in environments requiring robust performance under varied temperature conditions. As part of the PC166 specification, it suggests that this memory module is intended for use in systems requiring a 166MHz SDRAM, which was a common standard for enhancing the performance of systems by synchronizing the memory speed with the CPU clock speed. This particular model is designed for high-speed operation and reliability, making it an ideal selection for applications within computing, embedded systems, and telecommunications that demand consistent and fast memory access.
