HN27C4000G Series
524288-Word
× 8-Bit/262144-Word × 16-Bit
CMOS UV Erasable and Programmable ROM
Rev. 1
Nov. 10, 1994
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.
Features
• Organization: 524288-word
× 8-bit/262144-
word
× 16-bit (BYTE/VPP enables
selection byte-wide or word-wide)
• High speed: Access time 100 ns/120 ns/150 ns
(max)
Burst access time 50 ns/60 ns/60 ns
(max)
• Low power dissipation:
Standby mode; 5 µW (typ),
Active mode; 150 mW/MHz (typ)
• Fast high reliability page programming, fast
high-reliability programming and option
programming: Program voltage; +12.5 V DC
Program time; 3.5 sec (min)
(Theoretical in Page
programming)
• Inputs and outputs TTL compatible during both
read and program modes
• Pin arrangement: 40-pin EIAJ standard pin
compatible with HN62414/
HN62434
• Device identifier mode: Manufacturer code and
device code
ADE-203-311A (Z)
