DESCRIPTION
The SRM20V512SLMT
7
is a 65,536 words
×
8-bit asynchronous, static, 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. And –40 to 85
°
C operating tempereture range wakes it idial for portable equipment. The
asynchronous and static nature of the memory requires no external clock or refreshing circuit. Both the input
and output ports are TTL compatible and the 3-state output allows easy expansion of memory capacity.
