Frequently Asked Questions
What is the purpose of 'Dual-Port'?
It provides two independent ports with separate control, address, and I/O pins, allowing asynchronous access to the memory.
Does this RAM support high data transfer rates?
Yes, it is a high-speed 8K x 8 Dual-Port Static RAM that supports operation in nanoseconds (e.g., 15ns or 20ns depending on model).
What are the functional differences between the TQFP and PGA packages?
The device is available in ceramic 68-pin PGA, PLCC, and 64-pin TQFP packages for installation.
Can this device be used in harsh temperature environments?
Yes, models rated 'L' offer an Industrial temperature range (–40°C to +85°C), while others are military grade.
