DESCRIPTION
The SRM2AV400LLBT
8
is a 524,288words x 8-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. 3-state output allows easy expansion of memory capacity. The temperature range of the
SRM2AV400LLBT
8
is from –40 to 85
°
C, and it is suitable for the industrial products.
