The Hitachi HN27C4000 is a 4-Mbit UV erasable
and electrically programmable ROM that is
organized either as 524288-word × 8 bit or as
262144-word × 16 bit, featuring extra-high speed
burst mode that gives two times faster 4-word or 8-
byte serial access than normal. And also high
speed and fast programming are served as well as
the existing Hitachi 4M device HN27C4096 and
HN27C4001. Fabricated on advanced fine process
and high speed circuitry technique, HN27C4000
makes high speed access time and low power
dissipation in either active or stand-by mode.
Therefore, it is suitable for all systems featuring
high speed microprocessor such as the 80386,
80486, 68030, 68040 and so on.
