This document describes the features and characteristics of GS881Z18B(T/D)/GS881Z32B(T/D)/GS881Z36B(T/D) 9Mb Pipelined and Flow Through Synchronous NBT SRAM, including user-configurable Pipeline and Flow Through mode, NBT functionality, compatibility with other SRAMs, JTAG compatibility, on-chip write parity checking, power supply and interface options, etc.
The GS881Z18B, GS881Z32B and GS881Z36B are 9 Mbit synchronous static SRAMs offered by GSI Technology. They support user‑configurable Pipeline and Flow‑Through modes and feature NBT (No Bus Turn Around) functionality to maximize bus utilization.
These devices are available in 100‑Pin TQFP and 165‑Bump BGA packages, operate at 2.5 V or 3.3 V core supply, and cover commercial and industrial temperature ranges. Detailed pin‑outs, current specifications and ordering information are provided.
