Preliminary
CMOS IC
LC35W1000BM, BTS-70U/10U
Asynchronous Silicon Gate
1M (131,072 words × 8 bits) SRAM
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.
Features
• Low-voltage operation: 2.7 to 3.6 V
• Wide operating temperature range: –40 to +85°C
• Access time:
70 ns (maximum):
LC35W1000BM and LC35W1000BTS-70U.
100 ns (maximum):
