General Description
The HT23C040H is a read-only memory with high per-
formance CMOS storage device whose 4096K of mem-
ory is arranged into 512K word by 8 bits.
For application flexibility, the chip enable and output en-
able control pins can be selected as active high or active
low. This flexibility not only allows easy interface with
most microprocessors, but also eliminates bus conten-
tion in multiple bus microprocessor systems. An addi-
tional feature of the HT23C040H is its ability to enter the
standby mode whenever the chip enable (CE/CE) is in-
active, thus reducing current consumption to below
60 A. The combination of these functions makes the
chip suitable for high density low power memory appli-
cations.
