GENERAL DESCRIPTION
The Austin Semiconductor, Inc. AS8SLC512K32 is a 3.3V
16 Megabit CMOS SRAM Module organized as 512Kx32 bits. The
AS8SLC512K32 achieves very high speed access, low power
consumption and high reliability by employing advanced CMOS
memory technology.
This military temperature grade product is ideally suited for
commercial, industrial, and military applications when asynchronous high
speed switching and low ACTIVE opening power is mandated.

ABSOLUTE MAXIMUM RATINGS*
This is a stress rating only and functional operation on the
device at these or any other conditions above those indicated
in the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
**Junction temperature depends upon package type, cycle
time, loading, ambient temperature and airflow. See the Application Information section at the end of this datasheet for
more information.
Voltage of Vcc Supply Relative to Vss...........-0.5V to +4.6V
Storage Temperature.....................................-65°C to +150°C
Short Circuit Output Current(per I/O)............................20mA
Voltage on Any Pin Relative to Vss............-.5V to Vcc+4.6V
Maximum Junction Temperature**.............................+150°C
*Stresses greater than those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
