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
This allow random access of up to 1024 words within a
row at a 56/50 MHz EDO cycle, making the A42L0616
ideally suited for graphics, digital signal processing and
high performance computing systems.
