General Description
The HT23C040 is a read-only memory with
high performance CMOS storage device whose
4096K of memory is arranged into 524288 word
by 8 bits.
For application flexibility, the chip enable and
output enable control pins can be selected as ac-
tive high or active low. This flexibility not only
allows easy interface with most microproces-
sors, but also eliminates bus contention in mul-
tiple bus microprocessor systems. An
additional feature of the HT23C040 is its abil-
ity to enter the standby mode whenever the
chip enable (CE/CE) is inactive, thus reducing
current consumption to below 30 A. The combi-
nation of these functions makes the chip suit-
able for high density low power memory
applications.
