SMIC 0.25um 2.5V/3.3V SSTL3 I/O Cell Library

Overview

VeriSilicon SMIC 0.25um 2.5V/3.3V SSTL3 I/O Cell Library developed by VeriSilicon is optimized for Semiconductor Manufacturing International Corporation (SMIC) 0.25um Logic 1P7M Salicide 2.5/3.3V process. This library is fully compliant with the EIA/JEDEC standard, JESD8-8 Stub Series Terminated Logic for 3.3 Volts (SSTL3). The SSTL3 provides MOS push-pull interface designs and is especially optimized for major memory applications. It is intended to improve operation in situations where busses must be isolated from relatively large stubs. Comparing to the LVTTL solution, SSTL2 has the advantages of lower voltage swing, lower power dissipation and higher immunity to generated noise because of the differential receiver. There are two classes of output specifications for SSTL3, class I and class II, which are distinguished by drive requirements and applications. Class I is basically applied for point-to-point configuration, such as network applications; and Class II is mostly applied for 266MHz DDR SDRAM signaling.
