Overview

The LC35W1000BM and LC35W1000BTS-70U/10U are asynchronous silicon gate CMOS static RAM devices with a 131,072-word by 8-bit structure. They provide two chip enable pins (CE1 and CE2) for device select/deselect control and one output enable pin (OE) for output control. They feature high speed, low power, and a wide operating temperature range.This makes them optimal for use in systems that require high speed, low power, and battery backup. They also support easy memory expansion.
