General Description

The A42U0616 is a new generation randomly accessed memory for graphics, organized in a 1,048,576 -word by 16-bit configuration. This product can execute Write and Read operation via CAS pin.

The A42U0616 offers an accelerated Fast Page Mode cycle with a feature called Extended Data Out (EDO).

This allow random access of up to 1024(1K Ref.) words within a row at a 50/40/28 MHz EDO cycle, making the A42U0616 ideally suited for graphics, digital signal processing and high performance computing systems.
