The HM63921 is a first-in, first-out memory that
utilizes a high performance static RAM array with
internal algorithm that controls, monitors and
declares status of the memory by empty flag, full
flag and half-full flag, to prevent data overflow or
underflow.
Expansion logic warrants unlimited expansion
capability in width and depth. Both read and write
are independent from each other and their
corresponding pointers are designed to select the
proper locations out of the entire array serially
without address information to load or unload data.
Data is toggled in and out of the device through the
use of the write enable (
W
) and read enable (
R
)
pins. The device has a read/write cycle time of
30/35/45 ns. Organization of HM63921 provides a
9-bit data bus. The ninth bit could be used for
control or parity for error checking at the option of
the user. The HM63921 is fabricated using the
Hitachi CMOS 1.3 micron technology. The device
is available in DIP and SOJ.
