SRM20W117LLTT/SLTT2/7  
1M-Bit Static RAM  
Super Low Voltage Operation and Low Current Consumption  
Access Time 120ns (1.8V) / 70ns (2.7V)  
65,536 Words x16-bit Asynchtonous  
Wide Temperature Range  
DESCRIPTION  
The SRM20W117LLTT/SLTT2/7 is a 65,536 words x 16-bit asynchronous, random access memory on a monolithic  
CMOS chip. Its very low standby power requirement makes it ideat for applications requiring non-volatile syorage  
with back-up batteries. The asynchronous and static nature of the memory requires no external clock or refreshing  
circuit. It is possible to contorol the date width by the data byte control. Both the Input and output ports are TTL  
compatible and 3-state output allows easy expansion of memory capacity. The temperature range of the  
SRM20W117LLTT/SLTT2/7 is from –40 to 85°C, and it is suitable for the industrial products.
