DESCRIPTION
The SRM2AW216LLBT
1/7
is a 131,072 words x 16-bit asynchronous, random access memory on a monolithic
CMOS chip. Its very low standby power requirement makes it ideal for applications requiring non-volatile storage
with back-up batteries. The asynchronous and static nature of the memory requires no external clock and no
refreshing circuit. It is possible to contorol the data width by the data byte control. 3-state output allows easy
expansion of memory capacity. The temperature range of the SRM2AW216LLBT
1/7
is from –40 to 85
°
C, and it
is suitable for the industrial products.
