DESCRIPTION
OKI’s 0.8µm ASIC products, specially designed for mixed 3-V/5-V applications, are now available in both Sea Of Gates (SOG) and Customer Structured Array (CSA) architectures. Both the SOG-based MSM38S Series and the CSA-based MSM98S Series use a three-layer-metal process on 0.8µm drawn (0.6µm L-effective) CMOS technology. The semiconductor process is adapted from OKI’s production-proven 16-Mbit DRAM manufacturing process. Ideal for low-power portable applications, Altogether, the architecture provides maximum flexibility, meeting the needs of all 3-V, 5-V, and mixed 3-V/5-V signal requirements. SOG array sizes are designed to fit the most popular quad flat pack (QFP) packages, such as 100-, 136-, 160-, and 208-pin QFPs. MSM38S SOG-based designs are therefore ideal for pad-limited circuits that require rapid prototyping turnaround times. The MSM98S CSA Series is an all-mask-level superset of the SOG series, available in 29 sizes. The CSA offerings combine the SOG architecture’s logic flexibility with the higher integration yielded by optimized diffusion for faster and more compact memory blocks.
