General Description

The A42L0616 is a new generation randomly accessed memory for graphics, organized in a 1,048,576-word by 16-bit configuration. This product can execute Byte Write and Byte Read operation via two CAS pins.

The A42L0616 offers an accelerated Fast Page Mode cycle with a feature called Extended Data Out (EDO). This allow random access of up to 1024 words within a row at a 63/50/40 MHz EDO cycle, making the A42L0616 ideally suited for graphics, digital signal processing and high performance computing systems.
