General Description

The HT23C256 is a read-only memory with

high performance CMOS storage device whose

256K of memory is arranged into 32768 words

by 8 bits.

For application flexibility, the chip enable and

output enable control pins can be selected as

active high or active low. This flexibility not

only allows easy interface with most microproc-

essors, but also eliminates bus contention in

multiple bus microprocessor systems. An addi-

tional feature of the HT23C256 is its ability to

enter the standby mode whenever the chip en-

able (CE/CE) is inactive, thus reducing current

consumption to below 30

µA. The combination of

these functions makes the chip suitable for high

density low power memory applications.
