DESCRIPTION
Oki’s 0.25µm Application-Specific Integrated Circuit (ASIC) products are available in both Sea Of Gates (SOG) and Customer Structured Array (CSA) architectures. Both the SOG-based MG115P series and the CSA-based MG75P series use a five-layer metal process on 0.25µm drawn (0.18µm L-effective) CMOS technology. The SOG MG113P/114P series uses the same SOG base-array architecture as the MG115P series, but offers four and three metal layers, respectively. An innovative 4-transistor cell structure, licensed from In-Chip Systems, Inc., provides 30 to 50% less power and 30 to 50% more usable gates than traditional cell designs. The Oki 0.25µm family operates using 2.5-V VDD core with optimized 3-V I/O buffers. The 3-, 4-, and 5-layer metal MG113P/114P/115P SOG series contains 4 array bases, offering up to 588 I/O pads and over 2.4M raw gates. The 3-, 4-, and 5-layer metal MG73P/74P/75P CSA series contains 21 array bases, offering up to 868 I/O pads and over 5.4M raw gates. These SO...
